Composite Shake Shingles Offered in New Colors

DaVinci Roofscapes launches the Nature Crafted Collection 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 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.”

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

The new Aged Cedar color reflects a burnt reddish cedar tone. This color is generally found when there’s a transition from a new cedar shake roof into the weathered deeper tone. Mossy Cedar features a damp, greenish character. While in real cedar this is achieved by moss and lichen that are not good for the longevity of the roof, the color is one that people desire for their natural-looking shake roofs. The Mossy Cedar color captures that tone while taking away worries about the durability of the roof.

Finally, the new Black Oak color reminds people of natural cedar shingles that have been saturated with moisture and mold for many years. The color tells the story of dark, aged cedar on a home. Some people love this color, but the decaying natural cedar truly is not practical for a roof. Now, by recreating the mature, almost black bark coloring, homeowners have the mature-looking cedar color they want but with the durability of a composite shake.

“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,” said Rosewall. “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.”

The Nature Crafted Collection is available on all DaVinci Multi-Width and Single-Width Shake composite roofing tiles.

Adhesive Application Designed to Allow for Venting of LWIC

COLPLY EF for ribbon applicationSoprema Inc. announces the launch of COLPLY EF for ribbon application. The moisture-cured, solvent-free, polymeric adhesive is applied in ribbons as a solution to allow for the venting of vapor pressure and the migration of trapped moisture from lightweight insulating concrete.

COLPLY EF for ribbon application is packaged in cartridges, which will allow for the product to easily be applied in ribbons. The new application process will allow for the partial attachment of the SBS membrane or vapor retarder to address any concerns of blistering or issues caused by trapped moisture.  COLPLY EF is low odor and requires no hot torching, making it ideal for many applications with odor and heat restrictions, such as schools, hospitals and apartments.

“The ability to apply COLPLY EF in ribbons is just another way Soprema has created solutions that are needed within the industry,” said Matt Davis, product manager, Soprema. “The unique process will easily allow for venting to avoid trapped moisture and the structural damage that accompanies it resulting in an easier-to-use product and alleviating problems many contractors typically see in these applications.”

According to the company, COLPLY EF can be applied by loading 5-gallon pails into a gravity fed applicator, or by using the new cartridge packaging for use in the same battery powered applicator or multi-bead applicator commonly used for its DUOTACK products.

COLPLY EF Meets FM, UL, FBC, Miami-Dade and South Coast Air Quality Management District regulations.
