The Power of Vacations

My dad keeps telling me that kids today don’t work very hard. By kids he means me — and I’m 57. It seems every time I turn around, though, I see an article that offers the opposite conclusion: Americans work too hard. They work longer hours and take less vacation time than their counterparts in other countries. By some accounts, the majority of American workers don’t even use all of the time off they are entitled to take. The sad part is, most workers do so because they want to be more productive. But working too long and too hard makes us less productive, not more. Vacation time is not only beneficial for personal health and well-being. Vacations also increase productivity.

Human bodies and brains have their limitations. We need some downtime to stay healthy and focused. It’s also during periods of rest and relaxation that some of the greatest discoveries have been made.

Whether it’s Newton resting by an apple tree or Watson and Crick taking a break by the seaside, it seems every scientific breakthrough I read about in high school came about when someone was goofing off. The notion of an epiphany — a flash of insight that solves a troubling problem — often seems to coincide with a break from work.

The “eureka” moment is said to derive its name from the story of the ancient Greek mathematician Archimedes, who came up with a method of solving a tricky problem after he slid into a nice hot bath. The story goes that he was trying to figure out how to measure the volume of irregularly shaped objects. Stumped, he took a break at the local bath house, where he suddenly realized that he could make the determination by the amount of water an object displaced. He then ran through the streets screaming “eureka,” which apparently means either “I found it!” or “I forgot my clothes!”

As I worked on this issue of the magazine, which focuses on education projects, I thought of the long summer breaks we had as students, which I now know are frenzied periods of construction for the roofing industry. I also spent a week in northern Michigan, where I hiked some beautiful trails with my wife, Patti, and Josie the Wonder Dog.

I can’t claim that I had any great insights into the nature of physics or science — or even better ways to produce Roofing magazine — but I did manage to locate some dog-friendly craft breweries and take in some glorious views of lake Michigan. Here’s hoping it makes me more productive.

Three Shingle Installation Mistakes That Cause Major Problems

By following installation guidelines, contractors can produce a more professional-looking roof that will be far less likely to experience problems a year, two years, or even 10 years down the road.

A roof that isn’t installed precisely the way it was intended can be both unattractive and incapable of standing up to extreme weather conditions. On a laminate shingle roof, overlooking seemingly small details, such as shingle alignment and nailing, can lead to serious problems. Here are some of the most common details that, when improperly executed, can have negative consequences later in the installation or after completion of the roof:

  1. No Starter Shingles/Improper Alignment of Shingles at Eave and Rake

CORRECT: This photo shows the starter shingle being installed correctly. Proper alignment is crucial when installing the starter shingles. Photos: Atlas Roofing

The starter shingle’s two purposes are water protection and wind protection at the eave and rake. A starter shingle is used to seal with the field shingle at the first course along the eave and rake. This helps prevent wind and water from getting beneath the shingle in this critical location. The underlayment is a secondary water barrier if any moisture gets beneath the shingles.

Starter shingles are installed so they overhang the edge of the eaves slightly to allow for water runoff. Then a course of shingles is installed on top of the starter shingles, forming a front line of defense for blow-offs and water damage.

INCORRECT: When starter shingles are not installed, water channels can form where the shingles align across the first course. Photos: Atlas Roofing

When roofers don’t use starter shingles and install the first course of shingles directly onto the eave or rake, water channels can form where the shingles align across the first course. Moisture can then come into direct contact with the roof deck. Shingles farther up the roof are protected by the courses beneath them, which catch and divert any water that happens to drip between the edges. The first course of shingles needs the same defense from the elements.

Tip: Proper alignment is important when installing both the starter shingles and the first course of shingles. If the starter shingles are not secured correctly at the eave or rake, and the first course of shingles is not nailed down evenly across the top of the starter shingles, the roof may be at risk for wind and/or water damage.

Manufacturer’s guidelines for the proper overhang spacing at the drip edge or rake should be followed precisely. If the starter shingle overhangs the eave too much, a gust of strong wind may lift the shingles and cause a blow-off.

  1. Improper Nailing

The obvious purpose of proper nailing is to ensure that shingles stay in place and don’t cause leaks. Local building

INCORRECT: Nail heads should be flush with the top of the shingle. All three of the nails in this photo are incorrectly installed. The nail on the left is over-driven, the middle nail is at the wrong angle, and the one on the right is under-driven. Photos: Atlas Roofing

codes and manufacturers’ instructions give roofing contractors the directions they need to fasten the shingles properly to the roof deck. Guidelines specify the number of nails per shingle and where the nails should be placed.

In laminate shingles, the nailing zone is referred to as the “common bond” area of the shingle. The “common bond” area includes the double-layer portion of the shingle down to the exposure and constitutes the proper nailing area as identified in laminate shingle installation instructions. The “common bond” nailing area must be targeted correctly in order to obtain the proper wind performance as advertised by the shingle manufacturer. Properly

INCORRECT: The nailing area must be targeted correctly in order to obtain the proper wind performance. In this photo, nails are improperly placed both above and below the common bond area. Photos: Atlas Roofing

placed nails go through two layers of shingles – penetrating through the previous shingle course underneath – attaching them securely to the roof deck. Nails placed outside the common bond area can void the roof’s warranty and prevent asphalt shingles from performing as intended during extreme weather.

Tip: Pneumatic nail guns are popular among many roofers. The pressure on the gun should be set correctly before use. Nail heads should be flush with the top of the shingle. If the pressure is set too high, the gun will overdrive the shingle, causing it to sink into the mat. Too low, and nails will be under-driven, meaning they will stick out above the top of the shingle. Incorrect pressure can also cause nails to be driven in diagonally.

Wind and wind-driven rain can lift improperly nailed shingles and cause water damage to the roof and possibly blow-offs. Using either too many or not enough nails can weaken the shingle’s performance, which can also result in blow-offs.

Finally, roofers who prefer hammers should be skilled enough to drive nails consistently into shingles at the right angle, not over- or under-drive them.

  1. Improper Shingle Alignment

Roof shingles are intended to be precisely aligned, both vertically and horizontally. Roofers lay out each course of

INCORRECT: Proper alignment of the shingles is crucial. In this photo, the top shingle has been placed too high. Photos: Atlas Roofing

shingles in a staggered, stepped pattern (think of a brick wall). The shingle edges of one course must be offset from the shingles below. Edges lined up with each other would allow water to seep through to the roof deck.

INCORRECT: The shingle at the top of this photo has been placed too low. Photos: Atlas Roofing

Installing shingles too high or too low compared to the previous course can affect the exposure, which in turn would affect the aesthetics, wind performance and seal strength of the roof. An improperly aligned shingle course would be very noticeable and have a wavy appearance that is unattractive and amateurish.

Tip: Manufacturer’s instructions for proper shingle alignment are printed on the shingle wrapper.

Eliminating Problems Pays Big Dividends

Roofers who are careful to avoid these mistakes can avoid unintended problems after installation. Using a starter shingle at the eaves and rakes can ensure that the installation is off to a good start. Paying attention to proper nailing and nail placement within the common bond area on all courses all the way up to the ridge can optimize the roof’s performance against wind and rain. Finally, carefully aligning each course of shingles both vertically and horizontally will give the finished roof a professional appearance and help to improve the homeowner’s curb appeal.

Replacing a Roof Drain on a Structurally Sloped Steel Roof Deck

Figure 1. Roof drain detail. Photos: Hutchinson Design Group Ltd.

What is the number one goal of any building owner when it comes to the roof? They don’t want water pouring through their ceilings damaging the interior of the building. How do you keep water out of the building? By keeping the water on the exterior of the building and directing it to the roof drains or other drain locations, such as scupper or gutters. The roof drain is, on a basic level, one of the simplest details on the roof, and yet it is flashed incorrectly time and time again. This paper will walk you through the process of replacing a roof drain on a structurally sloped steel roof deck and installing the new roof system and flashing.

Photo 1. The sump pan and drain body have been installed. Photos: Hutchinson Design Group Ltd.

First off, we are going to assume that the current drainpipe is adequate to handle the existing water volume and drain its portion of the roof, and that the drain pipe is in good condition. Our new roof system will meet the current R-30 requirements for continuous insulation above the roof deck in a roof near Chicago. So, our roof system will be composed of a mechanically fastened substrate board on the steel roof deck, a self-adhering vapor retarder, two layers of 2.6-inch insulation mechanically fastened, a 1/2-inch modified gypsum cover board set in bead foam adhesive, and fully adhered EPDM membrane. (See Figure 1.) We will also assume that the roofing contractor is acting as the general contractor for our scenario.

Now that we have our parameters out of the way, what’s first? I have never met a building owner that likes construction debris inside of their conference room or classroom, so the interior needs to be protected prior to the removal of the existing roof drain. This can be as simple as some Visqueen, but the interior protection needs to be installed prior to the removal of the existing roof drain. The one question that seems to come up is, who is installing this protection? The owner? The plumber? The roofing contractor? I like to put this on the plumber. He knows when he is removing the drain and installing the new one.

Once the interior protection is installed, we need to coordinate the removal of the existing roof system and installation of the vapor retarder with the removal of the existing roof drain, as well as the installation of the new metal sump pan, drain body and lead and oakum joint to the existing drain pipe. (See Photo 1.) This all needs to be done on the same day so that the roof can drain properly and that the vapor retarder can be terminated onto the roof drain flange. This part is critical, as with experience this designer has learned that the vapor retarder can be used as the seal between the extension ring and the roof drain flange and that the O-ring can be eliminated. The sump needs to be fastened to the roof deck around the perimeter at 8 inches on center and be centered on the drainpipe. The drain body then needs to be set over the drainpipe and lead and oakum installed between the drain body and drain pipe.

Installing the New Roof

So, now we have the roof drain body and the vapor retarder installed. Now comes the new roof system. To meet our R-30 requirements, we are going to need a base layer of 2.6-inch polyisocyanurate insulation and 4-foot-wide, 1/2-inch-per-foot tapered insulation sump around the roof drain. This sump will get us to the R-30 requirements of 4 feet from the roof drain as required by the current codes. If my math is correct, that will leave 3.1 inches of insulation at the roof drain. We will need a reversible collar and threaded extension ring to accommodate this height. When setting the reversible collar onto the drain bowl, set it in water cut-off mastic. If the drain ever becomes clogged, this will help to keep water from seeping under the reversible collar and into the roof system. Next the threaded extension ring is installed. First, install some water cut-off mastic onto the treads prior to engagement with the reversible collar. Once again, this will help to prevent water from entering the roof system if the drain becomes clogged and backs up.

Photo 2. The extension ring has been set lower than the cover board (yellow) and water cut off mastic has been installed on the extension ring flange. Photos: Hutchinson Design Group Ltd.

One of the main questions that I receive from the roofing and plumbing contractors is, “How high should I set the extension ring?” Well, it varies per roof system, but for our scenario it needs to be set flush with the top of the tapered insulation. We set it here because we have our cover board that has yet to be installed, and when the clamping ring is installed it will be lower than the cover board. Now back to the insulation; the 2.6-inch insulation should be installed as close to the extension ring as possible, chamfered as required to fit under the flange. Next the tapered insulation sump is installed. This should be installed as close as possible to the extension ring flange and chamfered as required to fit beneath the flange. All voids between the extension ring and the insulation should be filled with spray polyurethane foam insulation.

Once we have our insulation installed, next comes the cover board. The number one thing with the cover board and roof drain is having the cover board cut perpendicularly to the roof drain flange. (See Photo 2.) Do notchamfer the cover board. Chamfering the cover board may ease the transition of the membrane onto the extension ring flange, but it creates an unsuitable substrate surface for the bonding adhesive. And in my experience, water seems to end up ponding around the roof drain and not dropping into the roof drain. This will also allow the roof’s drain clamping ring to sit flat and below the roof surface of the roof.

Photo 3. The membrane has been correctly cut in a cloverleaf pattern. Photos: Hutchinson Design Group Ltd.

Now that our cover board is installed, we have the membrane and its transition into the roof drain. Water cut-off mastic is to be installed on the extension ring flange. How much you ask? One tube. Load that flange up. Make two thick beads with it. I have never heard a contractor say, “Man, using all of that water cut-off mastic on the job really set me back.” It’s a small item, but it is worth it.

After the membrane has been installed and the clamping ring is set, it’s time to cut a hole in the membrane to allow the water to get to the drain and off the roof. How big should the hole be? As small as possible is what some contractors might say. I ask a question to you now: what is the goal of the roof drain? If you answered to get the water off the roof as quickly as possible, you would be correct. Then why would the contractor want to cut a small hole in the roof membrane that would restrict the flow of water into the roof drain piping and off of the roof? I am dumbfounded as well. When we detail the roof drain, we call for the membrane to be cut back to within a 1/2 inch of the extension ring in a cloverleaf pattern around the clamping ring bolts. (See Photo 3.) This way there is no confusion on how far back the membrane is to be cut. Set the drain dome and the roof drain detail is complete.

So, there you have it. Now the roof can drain properly with a brand-new roof drain with no problem (fingers crossed).

Fact or Fiction? Mixing Exhaust Vent Types Is Problematic

Too often, attic exhaust vent types are mixed, which can short-circuit the airflow pattern in the attic space. Photo: Jerry Becker

Airflow dynamics dictates avoiding it. The manufacturers’ Installation Instructions caution against it. Building Code cites it as a violation. And yet it remains one of the most questioned, challenged and, unfortunately, ignored tips offered during our best practices in residential attic ventilation seminars.

Is it really a problem to mix or combine different types of attic exhaust ventilation (ridge vents, wind turbines, gable louvers, box vents and power fans) on the same roof above a common attic? And if it is, why will you see it so often driving through any city in North America?

Lack of information, misunderstanding the science, and resistance to breaking old habits all contribute to the persistence of mixed exhaust vents on today’s roofs. We asked roofing contractors to share their experiences to help explain what could go wrong.

Problem No. 1: Inefficient Airflow

The main reason combining different types of exhaust vents is problematic is that it disturbs the proper flow of the attic air. To best help fight heat buildup, moisture buildup and ice dams, attic ventilation must be a balanced system of intake vents (placed low on the roof in the soffit or at the roof’s edge) and exhaust vents (placed at or near the roof’s peak). This allows the incoming cooler, drier air to enter the attic at the lowest possible location, flush out any built-up heat and moisture from inside the attic all along the entire underside of the roof deck, and push it out through the exhaust vents high on the roof.

Power fans are a good exhaust vent option. So are ridge vents. But not when they are mixed together on the same roof above a common attic. Doing so could lead to inefficient airflow and weather infiltration. Photo: Sean Toms

But, if two or more different types of exhaust vents are in place, it short-circuits the system. Instead of the primary path of air being into the intake vents and out of the exhaust vents, the path is mostly between the two styles of exhaust vents. One of the types of exhaust vents becomes an intake vent because air will always follow the path of least resistance. Air will always look for the easiest, closest path to take. That path happens to be between the two types of exhaust vents. And that limits the distribution of the air to the upper region of the roof; or worse, it keeps the air circulating between the distances of the two vents closest to the peak. That is not the best way to remove heat and moisture buildup inside an attic.

“About five years ago, I had a seasoned roofer with me that just started working for our company,” recalls roofing consultant Jerry Becker, Roof Life of Oregon, Tigard, Oregon. “We walked up to this apartment complex and I noticed that there was a power fan alongside can vents (box vents) and very little intake ventilation. I placed a friendly bet with him stating that I know what the plywood already looks like underneath without looking at it. He argued with me and said, ‘This roof has plenty of ventilation; look at all the vents up top and it even has a fan!’ So, I told him that the plywood next to the fan and the closest can vents and up to the ridge is going to be perfect, but as soon as you drop down about a foot from the power fan the plywood will be as black as night.

“We go inside the attic and what do you think we found? Black microbial growth on the lower section of the roof. It was so black that it was wet. It is important not to mix exhaust vent types. It’s bad enough when you do it on a single dwelling home, but that same mistake in a multi-family home is deadly. Think of all the moisture that is created by all the families — the washer/dryer, dishwasher, sinks, showers and ourselves.”

Inefficient airflow not only can damage the roof deck but it can also prematurely age the asphalt shingles. “I see examples of this all the time,” says Trevor Atwell, owner, Atwell Exterior Services LLC, Greenville, North Carolina. “Premature aging of roofing materials, buckled sheathing and signs of rotten wood all due to the moisture and heat being trapped.”

Ironically, sometimes the desire to mix types of attic exhaust vents seems reasonable on the surface. The homeowner or the roofing contractor wants to improve the flow of air. Thus, adding more vents — even if they are different types — seems logical. But more is only better in this case if it’s more of the same type. If improved airflow is the goal, double-check if the correct type of exhaust vent is being used to match the size and design of the roof/attic and if it’s being supplied with a balanced amount of intake ventilation. Mixing exhaust is not the solution.

Box vents or power vents installed near a ridge vent can lead to inefficient airflow, which can damage the roof deck and prematurely age asphalt shingles. Photo: Trevor Atwell

“I have seen this in action and until it was explained to me why I should avoid it, the concept of mixed exhaust was a mystery I had to punt to a colleague or competitor” says Tim Chapin, owner, Your Safe and Healthy Home, Akron, Ohio. “I had a condo project with a very complex roof made even worse by the presence of ridge vents, gable vents, soffit vents, and box vents. I was amazed there was a problem because it seemed to be ventilated to the max. But now I know it was short-circuited.”

“We see it often with ridge vents and a power fan just below the ridge vent, or with box vents combined with ridge vents; sometimes all three. We call it the Ventilation Trifecta,” says Tom Picha, steep slope consultant, Affordable Roofing Inc., Aurora, Illinois. “More is good in some cases. Not all.”

“I had a house I was asked to inspect. The house had a ridge vent, box vents and vented drip edge on it,” says Jeffrey Heitzenrater, owner, Triple Peaks Roofing & Construction Inc., Westlake, Ohio. “The first thing wrong was two different types of exhaust vents. Upon a complete attic inspection, we found mold and mildew. The insulation was also packed tight at the bottom, blocking off the intake system the previous company installed. This particular roof was only eight years old and all the plywood is now bad. This was caused from the trifecta — no intake, box vents turning into intake and venting out of the ridge vent.”

Problem No. 2: Weather Infiltration

When you ask a vent to perform a task it has not been designed to tackle, you’re rolling the dice against Mother Nature. An exhaust vent mixed with another type of exhaust vent that suddenly is pulled into intake airflow duties as a result of short-circuiting is not only pulling in air, but whatever the air is carrying that very moment: rain, snow, debris. Exhaust vents are not designed to ingest anything.

One of the consequences of mixing attic exhaust vent types can be weather infiltration, such as the snow in this photo. Photo: Ron Bastian

“In the winter when freezing rain turns into fine ice particles, I observed several times the lower exhaust vents on the roof becoming intake vents instead of exhaust as designed and drawing in ice particles and snow,” says Steve DuCharme, owner, Innovative Builders Roofing & Construction, Edmond, Oklahoma.

“I have witnessed snow ingestion into the attic due to mixed exhaust vents,” says Corey Ballweg, owner and president, Mid Towne Construction Inc., Cross Plains, Wisconsin.

“I recall an attic several years ago that had ridge vent and two power fans. They installed two because they were told one wouldn’t pull enough heat out,” says Paul Vosen, president, Degenhardt Home Improvement, Madison, Wisconsin. “The house had no overhangs and the attic floor was insulated with a good vapor barrier. I was there in the rain and both power fans were running. The attic was so tight that the power fans were actually pulling rain in through the ridge vent. Never have I seen that before — nor have I seen it since, but I never forgot it.”

The weather infiltration problems that can result from mixing exhaust vent types may not catch a homeowner’s attention right away. Not many homeowners regularly check their attic.

“I worked on a roof that did not have any intake vents at the soffit but did have two gable vents in addition, a power fan, and four box vents,” says Scott Dennison, president, Dennison Exterior Solutions & Gutter Topper, Saint Joseph, Michigan. “Over the brief 15-year life of the roof, when the power vent would turn on it turned the four box vents into intake vents which sucked water into the attic and destroyed the roof deck adjacent and below the vent.”

The most common exhaust mixture our seminar attendees tell us they see: gable end louvers combined with something else. Often the homeowner demands that the roofing contractor leave the gable end vent in place despite the fact a ridge vent is being installed as an exhaust vent improvement. The homeowner’s reasoning: The gable louver adds a decorative touch to the home’s exterior. Solution: Do what Ron Bastian does.

“I’ve noticed snow and wind-driven rain coming in a gable end vent which was combined with a ridge vent,” says Bastian, owner and president, Bastian Roofing Inc., Richfield, Wisconsin. “We closed up the gable end vent from inside the attic and this cured the problem I was called out for.” By closing up the gable vent from inside, the attic short-circuiting is eliminated and the homeowner can still enjoy the cosmetics from the exterior.

“We have witnessed numerous issues related to short-circuiting,” says Shawn Bellis, owner, EPIC Exteriors, Overland Park, Kansas. “We’ve seen fine wind-driven Midwest snow sucked into the exhaust vents — gable vents mixed with ridge vents, for example.”

There’s a Much Better Way

Inefficient airflow, mold, rotted decking, prematurely aging shingles, and weather infiltration into the attic does not have to be the final outcome. There’s a better way, but it may take a commitment to educating the homeowner and fellow roofing contractors. I believe that’s one of the reasons our best practices seminars are so well received.

“I had mixed attic ventilation on my own home,” says Sean Toms, quality control inspector, S & K Roofing, Eldersburg, Maryland. “After attending the seminar a few years ago, I looked in my attic. I had condensation on the roof nails. I had a ridge vent, fully vented soffit and gable vents. I closed the gable vents and added insulation to my attic floor. Problem solved.”

“I seem to run into mixed exhaust vents every week. Homeowners think that the more types of ventilation on the roof the better they are,” says Richard Turner, owner, RJ Turner Remodeling, LLC, High Point, North Carolina. “After explaining the things I have learned in the Air Vent Inc. seminars, they quickly understand the correct way things should be done.”

Tough Questions

I spent Father’s Day in a less than optimal spot — visiting my dad in the local hospital.

My father is 87, and a fall down the stairs resulted in life-threatening injuries. As I headed to the intensive care unit that first night, I didn’t know what to expect. However, I did know what my father’s wishes were regarding his care.

My dad is an attorney, and he prides himself on his estate planning, which is guided by two principles: taking care of his family and not paying a penny more in taxes than he has to. My brother, my sister and I know the details and who to contact when he passes away. But when my mom passed away unexpectedly more than a decade ago, we realized we didn’t know what her wishes were regarding critical care or even her funeral.

We learned from those mistakes. Our family discussed not only dad’s estate plan but his preferences for a funeral service (less funeral home, more Irish wake) and his thoughts about being kept alive by artificial means (no). I have a durable power of attorney in my briefcase and a form designating me as his patient advocate.

I was able to concentrate on the most important thing: making sure my dad got the care he needed. With the help of some talented and dedicated health care professionals, he’s doing much better now; he’s in a rehab unit and back on his feet. Hopefully we won’t need to look at his estate plans for a long time to come.

I can’t imagine going through the experience without that preparation. I thought back on the article about exit and succession planning in our last issue by Angie Lewis titled “Leaving Your Business Legacy.” In it, she details the advice of business planning experts Kevin Kennedy and Joe Bazzano of Beacon Exit Planning, who spell out retirement strategies. They also stress the importance of contingency planning — preparing for an unexpected illness or death.

If you haven’t read that article yet, I strongly urge you to do so. You can also log on to view an on-demand webinar on the same subject sponsored by Atlas Roofing.

Contact your attorney and get advice specifically tailored for your situation. Then talk to your family members and ask some tough questions. Take it from me, these conversations are not easy, but asking tough questions now can make difficult times a lot easier.

Composite Shake Shingles Offered in New Colors

Aged Cedar

DaVinci Roofscapes launches the Nature Crafted Collection of composite shake shingles, which includes three realistic, nature-inspired colors: Aged Cedar, Mossy Cedar and Black Oak. According to the manufacturer, each new color reflects different progressive aging processes found on real shake shingles. The Nature Crafted Collection is designed to capture the look of a moment and retain it for decades. The Nature Crafted Collection is available on all DaVinci Multi-Width and Single-Width Shake composite roofing tiles.

“The DaVinci Nature Crafted Collection is our most ambitious foray into color development in our company’s history,” said Ray Rosewall, president and CEO of DaVinci Roofscapes. “Our proprietary process technology enables us to recreate the natural warmth and softness of a patina previously only created by time and exposure to the elements.”

Black Oak

The realistic-looking colors on the composite shake tiles provide homeowners with the ability to gain the specific natural color

they desire for roofing tiles without the hassles of dealing with real wood. The DaVinci shake products have a lifetime limited warranty and will not split, crack, curl or fade, according to the company. Each tile has been crafted to resist fire and impact, along with high winds, mold, algae, fungus and insects. The composite tiles come in both wavy and straight grains throughout each shake tile to achieve an authentic wood look.

Research, time and attention have been dedicated to the development of the Nature Crafted Collection to assure a unique variety of colors appealing to homeowners nationwide. “We had our teams scanning the country to identify any colors that may be missing from our current selections,” said Rosewall. “This allowed us to identify three distinct ‘aged’ cedar palettes with different tones. In most cases when real wood has aged to the point where these beautiful patinas appear, the cedar itself begins to deteriorate as a roofing material. We have captured those

Mossy Cedar

natural colors and married them up with our composite shakes to offer long-term performance without the worry of failing roof materials.”

“People who truly appreciate the natural aesthetic that comes with the aging of a cedar shake tile will find the new colors in the Nature Crafted Collection very realistic,” Rosewall said. “The hues and tones replicated on these tiles are ‘consistently inconsistent’ … much like Mother Nature makes them. The colors in the collection allow people to have the look and character of naturally aged cedar roofs but with the performance features that are missing in the real cedar product.”

Three Polyiso Roof Insulation Options to Simplify Your Next Job

Pre-fabricated roof sumps direct water to a center drain point, helping to ensure proper drainage and minimizing installation time. Photos: Hunter Panels

As a roofing professional, you undoubtedly are familiar with polyiso insulation, as it is used in 70 percent or more of the commercial roofs in North America. Polyiso is popular with roofing professionals because it offers a high R-value per inch, is affordable, readily available, compatible with many roofing systems and meets both FM 4450 and UL 1256.

While you likely have specified or installed flat stock polyiso products, you might be less familiar with specialized product make-ups, which can help you simplify roof insulation jobs. Three options to be aware of are:

  1. Tapered systems
  2. Pre-cut hips and valleys
  3. Pre-fabricated sumps

Tapered Systems

As roofing professionals know, water is the enemy of the roof assembly. To prevent ponding and provide a positive slope to drain, polyiso insulation manufacturers offer sloped panels. Tapered polyiso typically comes in 4-foot-by-4-foot or 4-foot-by- 8-foot panel sizes, and in various compressive strengths. Commonly available slopes (per foot) include 1⁄16 inch, 1⁄8 inch, 3⁄16 inch, 1⁄4 inch, 3⁄8 inch and 1⁄2 inch. Tapered systems range from two-panel to eight-panel repeats, with such systems including varying thicknesses of flat polyiso insulation to complete the taper profile.

Photos: Hunter Panels

Tapered polyiso insulation installs similar to flat stock polyiso insulation, using adhesives or fasteners. As with multi-layer flat stock installations, when installing tapered products, crews should stagger the joints between layers to reduce potential pathways for airflow and condensation within the insulation layers.

Full-service polyiso manufacturers can design a tapered insulation layout based on the roof plan and specified R-value. They then will provide shop drawings showing where to place each tapered and flat stock panel to ensure positive slope and effective drainage across the entire roof.

Pre-Cut Hips and Valleys

In addition to the one-way sloped tapered panels discussed above, roofing professionals have access to pre-cut hips and valleys made of polyiso insulation. The hips and valleys help direct water on more complex roof designs. Well-equipped manufacturers will custom design and fabricate pre-cut, one-piece polyiso hips and valleys to meet your jobsite requirements including slope, and minimum and maximum thicknesses.

While crews can form hips and valleys by field-cutting tapered panels, ordering the pre-cut, one-piece panels reduces labor time and costs, as well as dumpster fees. It also prevents material waste caused by cutting errors.

Pre-Fabricated Sumps

Going a step farther in slope complexity, and further reducing ponding water, some polyiso insulation manufacturers offer pre-fabricated roof sumps. Commonly available as 4-foot-by-4 foot panels that ship flat, pre-fabricated sumps direct water from four directions to a center drain point. Some manufacturers also offer 8-foot-by-8-foot hinged sumps for greater design flexibility. All of these sumps offer a variety of starting thicknesses at the drain from 1/2 inch to 2 inches.

Choosing a Polyiso Supplier

Roofing professionals can obtain polyiso roof insulation from several suppliers. Which one is right for you? Following are a few factors to consider to help simplify your next roofing job.

  • Access to technical support: Some polyiso manufacturers provide customers with a variety of technical services. Having access to designers and estimators who work every day with specialized polyiso products takes the guesswork out of the process for you, saving time and money while helping ensure a high-quality roof.
  • Ready availability: Choosing a supplier with facilities throughout the country helps ensure timely access to specialty polyiso insulations when you need them.
  • Training support: To help your crews get up to speed faster on working with specialized polyiso roof insulation systems, look for a manufacturer that offers training support — whether via online videos, in person or on the jobsite.

Spring Forward, Fall Protect

Spring arrived late here in Michigan, and before the weather — and construction — began to heat up, I saw a press release from MIOSHA indicating the second year of its “Stop Falls. Save Lives.” safety awareness campaign would focus on the roofing industry. I called Nella Davis-Ray, Director of MIOSHA Consultation Education and Training (CET) Division in Lansing, to ask her why.

“Nationally and at the state level, we are pleased to see that overall, when you look at general industry and construction, there is a downward trend in work-related fatalities and injuries, and we like to think we play a part in that downward trend,” she said. “Even though we are seeing this downward trend, when you look at roofers’ fall-related incidents, and particularly when you look at roof-related fatalities, their rate is 10 times higher than the rate for construction workers as a whole. So, if there is any trade we can talk to about falls, the data shows the one group we should be focusing on is the roofers.”

The statistics were sobering, but the overall message was hopeful. “Our message is that all falls are preventable,” Davis-Ray said. “We really do believe that in MIOSHA.”

The key is making sure every employee is properly trained, has the proper safety equipment — and knows how to use it — and follows the jobsite-specific safety plan. According to Davis-Ray, the MIOSHA can help with all of those things — and the services are free.

The CET Division works independently of the Enforcement Division. It provides guidance to employers and employees through a variety of methods, including classroom training and educational materials including literature, videos, and a fall protection website, www.michigan.gov/stopfalls. The greatest tool of all, noted Davis-Ray, is a staff of consultants who can provide individualized training.

“I’m surprised how many employers, particularly contractors, are not aware that all they have to do is pick up the phone and call us,” she said. “At their request, we can schedule a time and location for one of our construction safety consultants to come out and work with them directly on safety and health issues.”

Consultants can review written requirements, explain interpretations of the standard, and answer specific questions about a project and whether or not a contractor might be in compliance. They can also help in crafting a comprehensive safety program. “We always try to look at the big picture,” Davis-Ray says. “The overarching issue is to have an effective system in place so that you ensure that safety is considered as a part of every contract.”

Davis urges contractors in every state to explore the free educational resources OSHA can provide. Michigan contractors can call 800-866-4674 or visit www.michigan.gov/miosha to learn more.

 

National Women in Roofing Taps Into a Powerful Force

In 2014, an organization devoted to helping advance the careers of women in the roofing industry was just an idea. Since then, the idea has become a movement. National Women in Roofing (NWIR) was officially launched at the International Roofing Expo (IRE) in 2016. The volunteer-based organization focuses on connecting and empowering women, and it has the support of more than 1,000 members — many of them men — and nearly two dozen sponsors. They all share the goal of working together to raise the professionalism of the roofing industry, bring more people into the field, and provide the education and training necessary to ensure its future success.

This February, Heidi Ellsworth handed over the position of NWIR chair to Shari Carlozzi. The two women shared their insights on the founding of NWIR with Roofing, detailing its current initiatives and plans for the future.

A Movement Is Born

Carlozzi and Ellsworth first discussed the idea of an organization to support women during a break at a meeting of the Midwest Roofing Contractors Association in 2014. As they shared their thoughts about working in a male-dominated industry,

a light bulb went on. “We started talking, and we realized there are a lot more women in this industry than people give it credit for,” Carlozzi says. “There’s a lot of women! And we said, ‘We should start an organization where women can gather to network, to learn from each other, to mentor one another, and to help empower each other’ — because we are in an industry that we love.”

Ellsworth and Carlozzi shared the concept with Steve Little of Dallas-based KPost, who was then MRCA president. “He said, ‘That’s a great idea! We’ll help incubate you.’ And that’s how we got started,” Carlozzi remembers. “It went viral.”

As they traveled the country in their respective work roles — Ellsworth as a partner in RoofersCoffeeShop.com and Carlozzi as national sales manager for HAPCO Inc. — they soon realized that a lot of other women had the same needs. Many were even exploring the same idea. “At every trade show we went to, both of us would hear this from so many women,” Ellsworth says. “They would say, ‘We need to spend time together. We need to network.’ And networking is a big one because it’s sometimes a lot easier for guys to get together to network and women are left out. It was something that a lot of women truly believed in.”

After talking to others in the industry, it became clear the organization had to have a national presence. “We looked ahead to the IRE in New Orleans in 2015 and decided to have a little get-together and see if people are truly interested,” Ellsworth recalls. “We had 75 women show up. It just grew from there.”

The group formed a leadership committee and held meetings at industry trade shows throughout 2015. “It was at IRE in 2016 that we officially launched National Women in Roofing,” Ellsworth says. “We realized very quickly that there was a tidal wave — a tsunami — of women behind us who really needed this. We realized we had to take this to a national level, and we did.”

The Four Pillars

Overarching goals of the organization are exemplified by its four pillars: networking, mentoring, education and recruitment.

“Our four pillars we started with — networking, mentoring, education and recruitment — have been the focus of what we’ve wanted to do from the start,” Carlozzi says. “Some people are a little bit more involved in education, some people are a little bit more involved in networking — it all depends on what works for you. We’ve stayed true to our four pillars, and that has been extremely helpful in giving women opportunities to engage in what’s most important to them.”

Ellsworth agrees, pointing out that networking events and mentoring initiatives developed hand in hand. “Our first events were networking events,” she says. “One of our themes is ‘from the rooftop to the boardroom,’ and we had top leaders at companies including GAF, ABC, Owens Corning, Johns Manville — all of these ladies showed up early and then stayed on and helped to drive this. We partnered with 28 founding sponsors that first year.”

Mentoring relationships seemed to blossom. “I wish we could all take credit for it, but it just happened so naturally,” Ellsworth says.

NWIR is launching a mentoring program this year, under the leadership of Mallory Payne and Melissa Walker, who head up the mentoring committee. “Mentoring has always been a big part of what we do,” Carlozzi says. “Men have more mentors than women do, and we want to change that.”

The education committee, led by Shelly Duhaime and Jennifer Keegan, is working on a full slate of educational sessions at industry events, as well as a series of webinars on topics such as networking, safety and business management. “Our education committee is on fire this year,” says Carlozzi. “People crave information. The only way we can excel in what we do is to keep learning.”

Carlozzi points to the NRCA’s ProCertification program as a model for educating the industry’s workforce and boosting professionalism. “We have to elevate the perception of the roofing industry,” she says. “We share the same values as the NRCA, and we want to speak with one voice to get the message across to people that this is a viable career option for you, whether you are a man or a woman in the trade, or whether you are looking for a career as a chemist, or an engineer, or a salesperson, or in data entry. It is a solid, reputable industry.”

It’s also an industry facing a worker shortage, so recruiting a new generation of workers is essential. The recruitment committee, led by Michelle Boykin and Chelsea Welsh, is active at employment fairs and career days, and NWIR is reaching out to other trade groups across the country to increase the visibility of the industry.

Part of the recruitment effort includes a commitment to helping women in crisis find employment and pursue a true career path.

Memberships and Sponsorships

The organization might be national, but it is also active at the local level. NWIR is developing councils across the country to cater to local educational needs and reach out to area community service opportunities. There are 29 local councils now, with a goal of reaching 50 by the end of 2018.

“It’s the best of both worlds for everybody because they get that national input through our epicenter — our newsletter and our website — and they can apply the information to what they are doing locally,” Carlozzi says. “We give local councils a lot of latitude to put together what works for them as long as they stay true to our four pillars and our national outreach program with women in crisis.”

Carlozzi and Ellsworth encourage all women and men to join the association. The membership fee is $60 per year. Half of the membership fee goes to develop and support local councils. “We made a very conscious decision to keep our membership dues very reasonable, and they are owned by the member,” Ellsworth notes. “If your career path takes you to another company, the membership goes along with you.”

Companies can help NWIR as sponsors. There are four levels of sponsorships. “We are also in the middle of our sponsorship drive, and that is a great way to get involved as a company,” Ellsworth says. “The value to the company — and its employees — is incredible.”

A Bright Future

Looking back at her tenure as the first chair of the organization, Ellsworth is proud of the group’s achievements and thankful for the friendships she’s made along the way. “It’s one of the greatest experiences I’ve had in my life,” she says. “The women I have met and the experiences we’ve had have been so empowering.”

As Carlozzi takes the helm, she plans to lean on the talented team of women ready to take the organization into the future. “It’s a little overwhelming when you look at it at first because we came so far, so fast, and we have to keep that momentum going,” says Carlozzi. “In the process, we’ve had some exceptional, outstanding women who have stepped up and taken on the leadership roles that are needed to develop and maintain a national organization like this.”

When the industry taps into everyone’s talents, everyone wins. Carlozzi sees that spirit every day at NWIR. “Everyone comes up with new ideas of how to make things better,” she says. “Everyone is open to new ideas and assistance, and everyone is freely offering it. No one feels threatened — we’re all empowered. That’s the beauty of it.”
