Help Homeowners Understand the Quality Proposition of a Tile Roof

Buying a home is the largest purchase most people ever make. Buyers work intensely to identify their needs and wants, assess the individual benefits of various choices and evaluate the long-term financial return to ensure they make a quality decision. Once living in that new home, kitchen remodels and reroofing can be the largest expenses faced by homeowners.

 In addition to increasing curb appeal, modern tile roofing systems and accessories offer an opportunity to improve the energy efficiency of a home.

In addition to increasing curb appeal, modern tile roofing systems and accessories offer an opportunity to improve the energy efficiency of
a home.

We all have firsthand, daily experience with our kitchen. We know what we like and what we don’t. Advertisements showing features and benefits of new appliances, more spacious cabinets and better lighting are appealing. Learning and planning for a new kitchen is fun and exciting. We know we will use it every day and we can show it off to our friends. We choose to do a kitchen remodel.

Reroofing is different. The process usually starts with a surprise—a roof leak a repairman fails to resolve. Then a second attempt, maybe a third, followed by an explanation that the system has reached the end of its useful and serviceable life. Reroofing becomes necessary to preserve the integrity of the home. It’s not fun and it’s not by choice. Compared to new stainless-steel appliances, soft-close drawers and a built-in wine cooler, it’s not exciting.

With little understanding of modern roofing, the first (and often only) question asked is, “How much is it going to cost?” If lowest initial cost was the only criteria for a roof, we would all have blue tarps overhead.

The true cost of roofing is defined by the life-cycle cost, which includes consideration of the initial cost, life expectancy, potential energy savings and potential insurance discounts.

A quality tile roof installation will set a home apart from neighboring homes now and will be a great investment to help the home garner the best sale price later. This is where a knowledgeable contractor can help a homeowner identify his or her needs and wants, assess the benefits of various choices and calculate the value of the given system.


Residential roofing is a functional part of the building envelope. Its primary purpose is to protect the home and its contents from the elements. Residential roofing is also a largely visible part of a home’s curb appeal. A tile roof will increase the curb appeal of a house when compared to similar homes with less substantial roofing materials.

Concrete and clay roof tiles’ resistance to weathering, hail, high winds and UV means that look of quality will be consistent from the day the roof is installed until the day it helps the homeowner get the best return on his/her original investment by enhancing the home’s curb appeal when the house is sold. Without the excitement of center islands and granite counter- tops, the homeowner needs help to be informed about options and benefits a tile roof can provide.


In addition to increasing curb appeal, modern tile roofing systems and accessories offer an opportunity to improve the energy efficiency of a home. The inherent insulation properties created by tile’s high thermal mass can be enhanced with above-sheathing ventilation, or ASV. These raised batten systems can “… offer a significant 50 percent reduction in the heat penetrating the conditioned space compared to direct nailed roof systems that are in direct contact with the roof deck,” says Dr. William Miller, Ph.D., P.E., Oak Ridge National Laboratory, Oak Ridge, Tenn.

The energy savings of ASV is recognized by the California Energy Commission, Sacramento, and included in the Title 24 Energy Code revisions for reroofing and alterations. (Learn more about ASV in “Details”, March/April 2015 issue, page 79.)

Swing Tape and Layout Methods Make Tile Layout Easy

When I see a home with a tile roof, my first thought is, “Nice roof”. A roof goes from “nice” to “Wow, that roof is spectacular!” when the installer pays attention to the details. Some details that make a difference are appropriate flashings, or chimney, skylight and wall metal work that is consistent and does not detract from the aesthetic look of the roof. However, nothing conveys the knowledge and skill of a craftsman more than crisp, clean, straight lines of tile, row after row.

Consistent row spacing (exposure) is aesthetically more appealing. It requires dividing the space between the top and bottom of the roof by the number of rows while avoiding a short course at the ridge. Using long division and 1/8- inch increments from a tape measure is one way to achieve this goal. However, that’s a method that challenges my calculator, let alone eager installers who just want to start pounding nails. They may believe it’s easier to deal with the ridge when they get there! It’s no wonder new installers can be intimidated by the layout stage of a tile roof installation. Even experienced installers may miss opportunities to minimize cuts, increase efficiency and achieve that “perfect look” we all admire.


Unless precluded by a specific manufacturer’s design, proper clay and concrete tile installation requires a 3-inch minimum overlap. That means a typical 17-inch-long concrete tile has a “maximum exposure” of 14 inches. If the goal is to space the rows evenly, we must first determine the location of the eave course and ridge course. For example, if we find the space between the eave and ridge courses is 140 inches, we can have 10 rows set at the maximum exposure of 14 inches. Perfect!

But what if the distance is only 135 inches? Setting nine rows at 14 inches will require us to cut 5 inches off of our top row. Cutting the tile would remove the fastener holes and tile lugs and make the top course uniquely short, taking away from a precision aesthetic. Most tiles have an “adjustable headlap”, meaning the overlap can be increased. If we set each of the 10 rows at 13 1/2 inches, we would absorb the extra 5 inches evenly over the entire slope with an extra 1/2-inch overlap per row. Row spacing would be consistent; fastener holes and lugs intact; and we would not have to cut tile, drill new holes and throw away the scraps.

The math is not always as easy as an extra 5 inches divided by 10 rows. Eighths and sixteenths don’t work well in long division. The TRI/WSRCA Concrete and Clay Roof Tile Installation Manual, from the Edmonds, Wash.-based Tile Roofing Institute and Morgan Hill, Calif.-based Western States Roofing Contractors Association has a Quick Reference Chart on page 27. It shows proper row spacing for sample eave- to ridge-row measurements. You may find situations where the chart is helpful.




Craftsmen develop “tricks of the trade” that make complicated tasks simple, their work easier or the finished product better. The “Swing Tape Method” does all three.

To avoid the math and use the Swing Tape Method, installers mark their measuring tape at the maximum exposure of tile they are using. Continuing with the example of a 17-inch tile and a 14-inch maximum exposure, the tape will be marked at 14, 28, 42, 56 inches, etc. Using the 135-inch eave- to ridge-course distance in the previous scenario, the installer would place the tip of the tape at the eave-row chalk line and run upslope to find the top-row chalk line at 135 inches. Seeing his tape is marked at 140 inches, the installer would swing his tape in an arc to the left or right until the 140-inch mark aligns with the top-row chalk line. Although the tape is marked in 14-inch increments, the now diagonal lay of the tape has shortened the distance of each horizontal row to 13 1/2 inches. The Swing Tape Method arrived at the same conclusion as the previous arithmetic. The installer marks the underlayment with chalk or a crayon next to each 14-inch increment on the tape measure. He repeats the same process at the other end of the slope and then chalks horizontal lines along the new markings on the underlayment.

Using a tape measure with this method requires marking each row onto the underlayment. This only should be done with chalk or a crayon. Scarring the underlayment with a nail or screwdriver can lead to premature failure of the underlayment.

A modern advancement to the Swing Tape Method uses Layout Tape instead of a marked tape measure. Layout Tape is a paper roll marked with red arrows highlighting the maximum exposure for the tile being used. In this example, the arrows would be at 14-inch intervals. Using the same process as with a marked tape measure, the installer can secure the Layout Tape, placing a red arrow on the top of the eave-row chalk line, then unroll the tape upslope to the top-row chalk line. Using the same 135-inch eave- to ridge-course example, the installer will find a red arrow 5 inches above the top-row chalk line. He will swing the tape to the left or right until the red arrow lines up with the top-row chalk line. The red arrows become the targets for the horizontal chalk lines. Because the Layout Tape is left in place, the installer avoids the step of marking each and every row on the underlayment.


Of course not all roof slopes are simple rectangles. Some roof designs are quite complicated and as installers we have to play the hand we are dealt. The Swing Tape Method can help you make the best of challenging situations by allowing you to virtually try out different layout options. If a slope has multiple ridgelines, you can set the tape to the most beneficial location. This may reduce your cutwork or put a short course in the least visible location. On larger sections, you may choose to adjust the row spacing to better accommodate ridgelines, headwalls or dormers. Be aware that midslope adjustment of exposure can result in a change to the diagonal line of the tile sidelaps but does not affect function.

Using the Swing Tape Method with Layout Tape or a marked tape measure appropriate for the tile being used will ensure proper exposure. It will also reduce cutting and increase your efficiency while laying the foundation for a picture- perfect installation.


1 Determine eave-course placement (consider eave closure, gutter, desired overhang) and snap a line to place head of the tile or top of the battens if battens are to be used.
2 Determine top-row placement (consider ridge riser board, ventilation, etc.) and snap a line to place head of the tile or top of the battens if battens are to be used.
3 Using Layout Tape or a marked tape measure, place an arrow or mark at the eave-course line. Measure straight to the ridgeline. Swing the tape to the left or right until an arrow or mark aligns with the top-row chalk line.
4 If you are using Layout Tape, fasten the tape. If you are using a marked tape measure, you must mark the underlayment at each mark on the tape measure.
5 Repeat this process at the other end of the roof. Snap lines between the arrows or marks on the underlayment.

Asphalt Roofing Provides Comprehensive Weather Protection for a Luxury Condominium

Working with the unique variables of a region and its climate poses a significant challenge to roofing contractors. Installing a roof system that looks beautiful and can stand up to ice, snow and freezing temperatures takes an expertise that only comes with experience. This is the case in the snowy and picturesque mountains of Park City, Utah. The city is a winter haven for skiers who vacation there, but the extended snow and cold season can deliver a beating to a roof.

The concrete tile roof and poorly ventilated deck were causing major problems for the building owner, not to mention the residents who live and rent there. Heat was escaping through the roof, causing the snow to melt and refreeze at the eaves.

The concrete tile roof and poorly ventilated deck were causing major problems for the building owner, not to mention the residents who live and rent there. Heat was escaping through the roof, causing the snow to melt and refreeze at the eaves.

The Grand Lodge at Deer Valley Resort, a luxury condominium development at one of North America’s top-ranked ski resorts, sits at an elevation of 9,000 feet in the mountainous area. Along with the breathtaking views comes an average annual snowfall of 350 inches. As a result, the 40,000-square-foot concrete tile roof of the lodge had begun to fail after only six years of intense weather and needed to be replaced immediately.

The concrete tile roof and poorly ventilated deck were causing major problems for the building owner, not to mention the residents who live and rent there. Heat was escaping through the roof, causing the snow to melt and refreeze at the eaves. Dangerous icicles would form, and noisy chainsaws were frequently needed to cut through the ice on the 5-story building. In 2013, the owner of the condominium decided to completely redesign the roofing system. IronClad Exteriors Inc., a Sandy, Utah-based roofing company had successfully installed roofs for Deer Valley in the past and was contacted by Deer Valley Resort Management to consult on the new design.

“Due to insufficient insulation and poor ventilation on the existing roof, ice dams were forming, tiles were cracking and the roof was falling apart,” says Eric Kircher, owner of IronClad Exteriors. “There was an architect involved in redesigning the roof … . I was asked to take a look at the design, and I recommended an asphalt shingle roof instead.

Kircher advised that a full asphalt roofing system with proper insulation and moisture protection would be able to withstand the harsh weather of the ski resort.

“Asphalt was the ideal material for the reroof for reasons that involve aesthetics, safety, and the long-term health and viability of the roof,” he notes. “I recommended a shake style because it really fit the architecture and look of the roof while being able to protect the building and residents from the weather conditions.”

Over the span of six months, IronClad Exteriors tore off the tile roof and installed a system they had used many times to help homeowners in the area protect their homes from ice and snow.

Over the span of six months, IronClad Exteriors tore off the tile roof and installed a system they had used many times to help homeowners in the area protect their homes from ice and snow. FlintBoard ISO NB (Nail Base) Composite Polyisocyanurate/OSB Roof insulation was installed over the plywood deck, followed by a 3- by 10-inch fascia board. WinterGuard HT advanced waterproofing underlayment and DiamondDeck High Performance Synthetic Underlayment were then added to provide important moisture resistance. Finally, the Presidential Shake TL asphalt shingles provided a beautiful look that matched the lodge’s breathtaking surroundings. The project was completed in November 2014.

The Grand Lodge’s new asphalt roof also contains a unique feature that sets it apart in form and function. IronClad installed 11,000 copper snow guards that offer another layer of weather protection. Snow freezes around the copper pieces and keeps it from sliding down the roof to form dangerous ice dams at the eaves. Lodge residents no longer have to walk underneath potentially hazardous icicles or listen to the sounds of manlifts and chainsaws that are used to remove them.

“The roofing system we designed had the unique ability to withstand that type of cold environment,” Kircher notes. “There will be no heat loss contributing to ice and snow on the eaves, and the insulation protects the interior of the lodge. These are high-end condominiums with finished ceilings and no attic space at the top where you can put more insulation, so the insulation had to be installed on the existing roof deck to prevent ice dams.”

The installation process went smoothly despite the challenges brought on by Park City’s weather. Snow can begin to fall as early as September and lasts through the spring, providing little time for construction projects to take place. Fortunately, IronClad had extensive experience with the roofing systems needed in Park City.

Boral Roofing Supports Charitable Organizations

Boral Roofing LLC, a provider of clay and concrete roof tile, is proud to support three charitable organizations in the expansion of the William Fry Drop-in Center, which serves homeless and at-risk youth in Southern Nevada. Nevada Partnership for Homeless Youth (NPHY), HomeAid Southern Nevada (HASN) and Nevada Women’s Philanthropy (NWP) have joined forces to complete a 2,600-square-foot facility expansion that broke ground Aug. 13. Boral Roofing has donated concrete roof tile for the facility through the company’s participation in HomeAid Southern Nevada, whose mission is to help build new lives for Southern Nevada’s homeless through housing and community outreach.

The expansion of the William Fry Drop-in Center, which served 5,000 cases in 2013, will increase the Nevada Partnership for Homeless Youth’s capacity for annual visits by 40%. The organization seeks to eliminate homelessness among Nevada’s youth population and to provide those it serves with opportunities for a quality future. NPHY is the only youth service provider in the state with a continuum of care extending from street outreach and 24-hour crisis intervention services to a full-time drop-in center and independent living program.

“Boral Roofing is proud to participate in such an important community project with HomeAid Southern Nevada,” said Stephenie Ireland, Boral Roofing’s Nevada Area Sales Manager and Board Member of HomeAid Southern Nevada. “The Nevada Partnership for Homeless Youth provides a vital service for the betterment of this community and deserves the support of the building industry.”

The tile donated to the project is Saxony Split Shake tile, which recreates the aesthetic of hand-hewn shakes whose benefits include superb performance and durability, low maintenance, energy efficiency and fire resistance. Cooper Roofing & Solar, a HomeAid Southern Nevada building partner, will complete the roof tile installation. Construction of the facility expansion is anticipated to be complete in October.

“We have had the great fortune to have Boral Roofing not only as a national HomeAid America sponsor, but as a generous, active member of our local Board of Directors,” said Caitlin Shea, executive director of HomeAid Southern Nevada. “We are so grateful for the Boral Roofing donation to this project. Because of this generosity and support, we are able to help Nevada Partnership for Homeless Youth double their facility space and help 40% more homeless and at-risk youth in our community.”

The 2,600-square-foot expansion brings the facility to a total of 4,000 square feet and includes the conversion of the facility’s existing administrative offices into youth service areas and a new kitchen, designed not only to serve the daily nutritional needs of the youth, but also allowing room for group learning lessons. The expansion will more than double the size of the existing center, and will also include a computer lab and staff office space, basketball court, gym, art and music rooms, and additional private areas for in-taking clients and tutoring.

Tile Roofing: Closed Valleys with Low-profile Tile

Batten extensions are installed on standard tile W valley metal.

Photo 1: Batten extensions are installed on standard tile W valley metal.

A common failure point on steep-slope roof systems is at valleys. Often, aging material, improper fastening, lack of maintenance and ice dams make valleys vulnerable. A common cause of valley troubles with tile roofing occurs when flat tiles are used in areas where closed valleys are preferred and a simple installation requirement is missed.

The Tile Roof Institute (TRI) Concrete and Clay Tile Installation Manual for Moderate Climate Regions allows for open (flashing exposed) and closed (tiles meet over flashing) valley installations. Installers develop a preference based on their experience with the local climate. Contractors also consider job-specific environmental conditions, aesthetic preferences, pitch and maintenance needs when choosing from valley-installation options.

Although there are a wide variety of flashing and installation options for valleys, one important requirement is often overlooked and can cause leaks with low-profile tile. The specification is listed on pages 48 and 49 of the installation manual: “When a flat profiled tile is installed as a ‘closed valley’, a ribbed valley metal or single crown valley metal with batten extension shall be used.”

Batten extensions are installed on standard tile W valley metal.

Unobstructed water flow in the valley flashing is critical. A flat tile installed directly onto standard valley flashing in a closed method restricts water in the valley flashing during heavy rains and may cause it to overflow. This can speed degradation of the underlayment and may cause rot in the battens and decking. A closed-valley installation can be repaired by replacing the standard tile valley flashing with the correct ribbed metal or by adding a batten extension to each row (see photo 1).

Because medium- and high-profile tiles have a natural cavity between the flashing and tile, this requirement only applies to low-profile tile. According to the TRI installation manual, the definition of a low-profile tile is, “Tiles, such as flat tile, that have a top surface rise of 1/2 inch or less.” Most tiles with a wood grain, lined or brushed surface still fall into the low-profile category and will require batten extensions or ribbed valley flashing.

When using a counter-batten system, or raised batten, the battens themselves can be extended into the valley because they are elevated on a pad or shim. In photo 2, a ribbed valley flashing and an elevated batten are used. Fasteners are not installed in/through the valley flashing.

Tile installers are craftsmen and each develops his or her own approach to valley details. Depending on the length of the valley and the tributary area, installers may flare or gradually open the width of the valley tile cut. Experienced installers may make a cut (dog ear) to the point of the tile that is overlapped by the succeeding row. Before accessory products, like ribbed valleys and batten extensions, were commercially available and before manufacturers improved the lug design, installers often removed lugs with their hammers. They developed propping and gluing skills to avoid creating a dam with their installation. Now the accessories and flashing designs make this type of installation better and easier.

Despite the variety of tiles within the low-profile category—some are flat on the back side and fastened directly to the deck, some have lugs on the back that can also utilize battens for attachment— all low-profile tile installed in a closed-valley method requires ribbed flashing or batten extensions unless precluded by manufacturer design and/or approved by the local building inspector.
