Homeowners often seek to remove heavy snow from their roofs. We designed our home to handle a substantial snow load and selected a low roof pitch, hoping to keep fallen snow in place on top of the house. This is because snow, on average, has an R-value of 1 per inch of snow. That means that our recent 15″ snowfall added R-15 to our R-50 insulated roof, helping to further reduce energy loss from the house. Pictured above is the right side of the garage roof with an entire slab of snow and icicles inching their way off. By design, neither rain nor snow falls over an entrance to the house.
