Roof insulation is a vital part in insulating your home and is the number one most helpful space to insulate in terms of reducing your energy bill. Since hot air rises, roofing insulation will capture the heat from inside your house during the cold months and keep your home feeling snug. But it’s also helpful when you have your AC on. When the heat is beating down from the sun onto your roof, your roof absorbs some of the heat. This can then be transferred into your home, making the AC work harder in order to cool your house. Roof insulation keeps that heat out of your attic and the rest of your home. Roofing insulation can help keep both heating and cooling and expenses down.
The great thing about roofing insulation is that it keeps your attic warm as well as the rest of your home underneath. One way to install attic insulation is with rigid foam insulation boards. These are installed on the *bottom side* of the rafters and offer a thorough enclosement of the attic while also allowing for extra room in the attic. Spray foam insulation is another popular choice and a great option. It is a much easier option when you have a complicated roof since it will form into whatever shape the roof is. Spray foam is sprayed directly onto the rafters of the roof and it then expands to fill the space, sticking the ceiling. It then hardens and becomes a barrier with a high R-value.
