In some parts of the country roofing materials experience very harsh weather with extreme temperature change. The high country in the Rockies or Sierras is very indicative of this. In these mountain areas daily temperature swings of 30 to 40 degrees are common and 50 degrees or more are not unheard of. The ambient temperature can be 75 degrees with a roof temperature of 120 degrees or more during the day and then the temperature can fall considerably below freezing overnight. This change in temperature, especially if moisture is added to the mix, can be very troublesome. If a roof covering absorbs moisture and goes through-freeze thaw cycles there can be damage that results in crazing, cracking, splitting, etc. Over time these freeze-thaw cycles can destroy a roofing product.
At DaVinci Roofscapes we have designed our tiles to be impervious to freeze-thaw. DaVinci tiles don’t absorb water so there are no issues with the tremendous force of freezing water. In addition, DaVinci tiles are very thermally stable, in fact the coefficient of thermal expansion is 10-3in/in °F. What this means is that the DaVinci 12” slate tiles expands 1/12” with a 100 degree temperature swing. Because of this you don’t get the buckling or movement that puts strain on fasteners as some products do.
DaVinci Roofscapes is a very popular roofing product for the resort areas of the Rockies and Sierras for a reason; it works. Well, also because it looks great!
