RoofingHeavy Snow Loads On Roofs Can Be Dangerous!
2/02/11
I Had seen this in the news earlier today. PLEASE
NOTE: Roofs are designed to carry a certain maximum load per square foot (PSF). And even if the
load (snow) is close to it's maximum the length of time a snow load sits on a roof matters also. (Especially
when more snow or moisture/rain is added)
Moral of the story: If you have a building with a flat roof (or flat roof section or a low pitched roof) check it often in the winter. Snow can drift up putting an unbalanced load on portions of the roof which can easily exceed the maximum . Clean the roof off periodically over the winter. And be safe while doing so!
