The answer is yes! Insulation is a vital element to your home’s energy efficiency. The sole purpose of insulating your roof is to help maintain a warm environment during the winter and a nice cool temperature when the heat rises in summer. Roof insulation is installed on the roof slope itself, above and below the rafters.
In the United States, insulation became a requirement in home building codes in 1965. Here’s a little history to why insulation has always been thought of and the reason why now it is something that you must have at home.
Always remember to make sure to ask your roofing contractor about the insulation conditions and whether you need to make any changes to it.
