Composite shake, tiles gain more space on roofs

DaVinci Roofscapes has introduced a 12-inch-wide polyethylene composite slate roofing tile called Province Slate that it said offers a timeless beauty for both historic and modern projects.

The tile, which has a fixed 8-inch exposure, evokes a historic nature with nonrepeating beauty at a competitive price point compared with other composite roofing products, according to Mark Pagel, general manager for DaVinci Roofscapes.

Province Slate also has a Class A fire rating and Class 4 impact rating so it can be used for commercial projects.

"Province Slate opens the door to people having traditional slate single-width exposure on a home at a price that is competitive with architectural asphalt and other high-end roofing options," Pagel said.

Manufactured in Kansas, Province Slate has a backside rib structure and self-aligning ledge for fast installation.

"The tiles are 5/8-inch deep and have a true, historical look to the slates, giving them a deep shadow line and authentic look," DaVinci spokeswoman Wendy Bruch said in an email.

The 8-inch profile of Province Slate is a solid addition to the DaVinci product line, Bruch added, pointing to the roofing trend to have a variety of exposures.

The tile has seen fast acceptance everywhere from California to New England, where it can withstand freezing temperatures without expanding or contracting, Bruch said.

DaVinci products like Province Slate tiles are made of virgin resins, ultraviolet and thermal stabilizers, and a highly specialized fire retardant, Pagel noted.

"The result is a roofing tile that is ideal for any climate," he said. "Whether used at a seaside location with constant salty air conditions or in the snowy mountains of Colorado, Province Slate is right at home."

The tile received a silver award from Products magazine, a companion of Pro Builder, in the exteriors category recognizing innovative and impactful products of 2022. The tile was described as historically authentic with an attractive price tag.

CertainTeed LLC expanded its line of Landmark-brand asphalt roofing shingles with a product called ClimateFlex that combines the beauty and dimensions of wood shake with the performance of rubberized polymer to withstand extreme weather.

The shingles are composed of a fiberglass mat base and ceramic-coated mineral granules tightly embedded in a water-resistant asphalt. A dual-layer design emulates the dimensionality of true wood shake and guards against the elements. ClimateFlex received a Class 4 rating for protection against hail damage.

The rubberizing aspects of the shingle make it pliable in cold weather, which allows contractors to install it in low temperatures that make standard shingles stiff and brittle.

CertainTeed also is introducing Grace Select, a smooth surface roofing underlayment made up of two waterproofing materials — a rubberized asphalt adhesive backed by a layer of high density cross-laminated polyethylene.

The underlayment is 25 mils (0.64 millimeters) thick, making it lightweight and easy to handle and apply. The company said the rubberized asphalt formulation allows the membrane to meet industry standards for fastener sealability compared with products that are thicker and heavier.
