I typically find that the depth of the structural framing required to support snow loads on flat roofs in my area coincides nicely with the amount of insulation I’m required to provide anyhow. So a 12-inch framing depth allows room for the right amount of insulation in the cavity. And whenever it snows, the flat roof supports an additional insulating blanket. The R-value, or resistance to heat flow, for snow is about R-1 per inch. That means 12 inches of snow on a flat roof creates an additional R-12 of insulation that arrives at a time of year when you most need it. This image depicts another benefit of flat roofs: They can be extremely low. Combined with the snow-catching ability, low and flat roofs are able to blend in with their natural surroundings quite seamlessly.

The higher the R-value, the better the thermal resistance. You may have heard the term “R-value” when discussing thermal insulation. Here in Europe, we more often talk about the U-value (the inverse of the R-value) or the lambda value of a material. Lambda and U-values work the opposite way, with lower values representing higher performance. All of these values are meant to help you understand the thermal resistance of a certain material or combination of materials to conductive heat flow. In the U.S., it’s actually legally required to provide the R-value of certain building materials at the point of sale (and sometimes in the advertisement).The intention of this law is to increase consumer awareness and prevent false claims about the potential of insulation components. However, the R-value itself can be tricky to understand.

Call in the pros. Don’t hesitate to call in a plumber, especially if you cannot access the frozen pipes. But if it’s 6 a.m., no one is taking your call and you want to get working on the problem right away yourself, here’s what to do.Find a plumber on Houzz
