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.”

GreenSlope’s New and Improved Formula Provides an Environmentally Friendly Solution to Ponding Water

GreenSlope is a roof leveling compound that helps eliminate ponding water on flat rooftops by filling in low areas, returning the roof to its original slope to achieve positive water flow to desired drainage areas. Following advanced in-house innovation and successful market testing, GreenSlope has been re-engineered for 2018 and now ships with a new and improved formula.

GreenSlope’s new formula features an improved adhesive, dramatically shortening the curation period from 24 hours to 2 hours, which allows for same-day topcoating. GreenSlope has also upgraded to finer-grade EPDM granules, which are less porous, easier to work with, and offer superior UV resistance and longevity. GreenSlope’s robust adhesive forms an exceptional bond with a wide variety of roof systems including single-ply, modified bitumen/BUR, metal and foam roof systems. The cured material is similar to a professional running track or premium playground surface, able to withstand extreme climates and as well as foot traffic.

At 20 percent the weight of concrete alternatives and half the weight of ponding water, GreenSlope reduces stress on the roof system by facilitating proper water drainage to extend the lifespan of the roof at a fraction of the time and cost it takes to install a new drain or tapered insulation. GreenSlope’s UV-stable compound can endure frequent freeze/thaw cycles and resists wear and tear while remaining flexible to absorb surface stresses. Highly malleable, GreenSlope can be used in a wide variety of practical scenarios including around low drains and scuppers, as walk pads and pitch-pan filler, for protection around curbs, HVAC units and more.

The product can be easily applied over low areas using a trowel and straightedge to smooth and level. For best results, additional topcoat application is recommended to achieve reliable waterproofing and match the aesthetics of the existing roof. GreenSlope is compatible with most topcoats including white acrylic, aluminum mastic, modified mastic, elastomerics, emulsions, and membranes.

The problem of ponding water offers service divisions an opportunity to open new doors with prospective clients. Ponding water can be found on eight out of 10 flat roofs and is one of the most commonly reported concerns of contractors and building owners as it can cause leaks, structural damage, membrane damage, algae and mold growth, slip hazards, insect problems, voided warranties, and premature failure of roof systems. Conventional options to deal with ponding include installing a new inner drain or adding tapered insulation, but these options are often expensive for building owners and not always necessary. GreenSlope’s preventative approach helps building owners maintain their roof asset while maximizing rooftop ROI. Additionally, going green offers potential LEED credits.

GreenSlope is manufactured and distributed by United Asphalt.

Kemper System Features Cost-Effective ‘Cool Roof’ Solutions

Kemper System America Inc. now offers two cost-effective ‘cool roof’ solutions for prolonging the life of metal, BUR, modified bitumen and aged single-ply roof systems.

Roof Guardian RG-170 is an elastomer-based coating system ideal for extending the life of many types of roofing assemblies. Formulated using a 100 percent acrylic polymer base for enhanced adhesion and durability, the coating features a high Solar Reflectance Index (SRI) rating of 109 and is Class A fire rated. Roof Guardian RG-180 is a fiber-reinforced elastomeric coating with an acrylic polymer base, ideal for metal, concrete, single ply, modified bitumen, and granular cap sheets. It offers an SRI rating of 108.

“Kemper System has been at the vanguard of liquid-applied roof waterproofing solutions for decades. These two new white Roof Guardian coating systems offer a quick and cost-effective approach for transforming many kinds of existing low-slope roofs into a cool roof that can help building owners cut cooling costs,” says Jim Arnold, Director of Product Development for Kemper System.

Part of the company’s Roof Guardian Technologies line, the roof coatings can be quickly applied with a commercial-grade sprayer or roller.

Innovative Roofing Insulation Appeals to Owners, Architects

Because Rich-E-Board roofing insulation is light and easy to install, it lowers the cost of delivery and handling and can reduce labor costs by more than half.

Because Rich-E-Board roofing insulation is light and easy to install, it lowers the cost of delivery and handling and can reduce labor costs by more than half.

It’s exceptionally thin and easy to install. It delivers an R-value of 50 to commercial, industrial and government buildings. Now, Rich-E-Board, the innovative new roofing insulation, is enjoying a groundswell of interest from building
owners, contractors and architects seeking to drive down construction costs and boost energy efficiency.

Rich-E-Board recently received a patent for its proprietary Vacuum Insulated Panel—two polymeric foam cover boards that sandwich the panel—and the adhesive ribbons that bind the boards and panel together. This ultra-thin insulation offers a certified alternative to a huge commercial roofing market—billions of square feet in construction every year—challenged with
meeting stringent standards for energy efficiency.

While conventional insulation requires a thickness of 15 inches to reach an R-value of 50, Rich-E-Board achieves the same result at just 1.5 inches thick. Rich-E-Board can be installed on most roof deck types, including ballasted roof systems, and can support all conventional low-slope roof systems.

Rich-E-Board’s design delivers significant advantages:

  • Lower energy bills: Achieving an R-value of 50 can cut a building’s heating and cooling costs by 8 to 10 percent, according to the GSA.
  • Simpler retrofits: Rich-E-Board enables retrofitted structures to achieve required R-values in less time, with fewer materials, and without costly and destructive building modifications.
  • Reduced construction costs: Because Rich-E-Board is light and easy to install, it lowers the cost of delivery and handling and can reduce labor costs by more than half.
  • Design flexibility: With its slim profile— especially compared with multi-layer insulation— Rich-E-Board saves space, expanding the design options for architects.

Rich-E-Board is also fireproof and water and mold resistant, notes Joanne Collins, president and CEO of R-50 Systems, maker of Rich-EBoard. “Our team focused on creating a game-changing alternative,” Collins says. “Rich-E-Board fills a significant
void in the marketplace by providing an insulation system capable of meeting today’s tougher energy standards.”

Success in the Field

Rich-E-Board has made a successful transition from the drawing board to the marketplace. Owners and architects have taken advantage of the insulation’s slim profile and high R-value on several building projects.

At a government building in Chicago, for example, owners chose to install 3,600 square-feet of Rich-E-Board as part of a roof retrofit aimed at lowering lifetime energy costs. Rich-E-Board’s slim profile also cut construction costs by more than $20,000 by streamlining design and installation.

At the Cohen Courthouse in Camden, N.J., Rich-E-Board was selected for the roof retrofit, eliminating the need for expensive building modifications that would have been required for conventional insulation. The decision lowered the project cost by $200,000.

Earlier this year, Rich-E-Board was awarded a patent for its design. More recently, the insulation earned its first LEED 4 designation.

“We’re seeing a huge increase in Rich-E-Board as the roofing market learns more about the benefits it brings to the commercial roofing,” Collins says. “This product fills a significant void by providing an insulation system capable
of meeting today’s tougher energy standards.”

Collins notes that, in addition to the $5 billion annual market for commercial roofing, Rich-E-Board can be used in walls and other building applications. Rich-E-Board is 99 percent recyclable and made entirely in the U.S.

According to the manufacturer, Lucas #8660 creates a non-hardening, weathertight seal. Designed as a non-skinning, non-sag sealant, the product exhibits high moisture resistance, with an exceptional ability to absorb sound and movement. Lucas #8660 comes in a neutral color, guns easily in cold or hot weather, and is packaged in 10-ounce fiber cartridges, 12 per case.

“Lucas #8660 won’t stain substrates and exhibits primerless adhesion to most roofing and building materials, including Kynar,” says Jason Morris, technical sales representative for Lucas. “The product is easy to gun and tool, even in cold weather, and is also self-healing.”

The butyl sealant can be used in a variety of metal roof applications where a low modulus sealant is desired, including metal roof panels, ribs, standing seams, and ridge cap flashing, as well as metal wall panels. Lucas #8660 is also recommended for OEM trailer and RV application, installation of walk-in coolers and freezers, and as a vapor barrier sealant. In addition, Lucas #8660 can be used as a sound-deadening sealant in installation of acoustical ceilings as well as both gypsum and metal wall panels. It is not designed for use as a single-ply roofing adhesive or lap adhesive.

When applying the sealant, the surface to be sealed must be dry and free of dirt or loose corrosion particles. A primer is not needed. Simply apply the sealant to the area as desired. Tooling is not normally necessary. The product can be cleaned with Lucas #125 Safe Solve. It also has a long shelf life, remaining active two years from the date of manufacture.

“We feel that this will be an excellent addition to our product line whether you are restoring, renovating or maintaining building structures,” states Morris.
