Freeze/Thaw No Trouble for DaVinci Polymer Roofing
5 degrees in Nashville. -2 degrees in Atlanta. This past winter's deep freeze stretched far deeper into the South than usual. The good news is that, when these temperatures "heated up" to the 20's and 30's, roofers were back out installing DaVinci Roofscapes polymer roofing materials.

What those southern roofers might not know — because they don't always experience extreme temperature conditions — is that DaVinci composite roofing materials are designed to be installed in areas where freeze-thaw conditions are common. These hard-working imitation slate and synthetic shake products don't absorb water so there aren’t the same freeze thaw issues that some roofing materials have.That means that even if a DaVinci roof has moisture on it, there will be no damage during freeze-thaw cycles like cracking or splitting of tiles.
Made of 100% virgin polymer resin, simulated shake roofing and composite slate tiles from DaVinci don't react the same to colder weather conditions as natural roof products. For example, a wood shake roof goes through freeze/thaw cycles constantly in some weather environments. This means that it is common to see cracking and splitting on some cedar roofs. In some areas of the country, the daylight to nightfall temperature swings alone can cause damage to cedar shake roofing. (See DaVinci Shake is the Best Fake Cedar Shake on the Market)
In addition, DaVinci plastic roofing materials are very thermally stable. A 12" synthetic slate roof tile expands just 1/12" with a 100 degree temperature swing. Thanks to this engineering feat, you don't get the buckling or movement with a DaVinci tile that can put strain on fasteners as with some other products.
