Insulating The Underside Of Your Roof

But the best solution is actually to insulate both the attic floor and the underside of the roof.

Insulating the underside of your roof.

If you re insulating the roof directly to insulate the roof itself you either use spray foam or retrofit with it with rigid foam board. An advantage of spray foam is it s quick whereas foam board needs to be cut and measured which can be a chore. Use these questions to decide which. In this way you prevent the heat from the rooms below escaping to the attic rooms above.

If so fix that first. You can then install. At the same time the areas below the roof benefit from increased comfort both during the winter and the summer. An unvented attic differs from a conventional vented attic in that there is no direct venting of the attic.

Then you could simply insulate the pitched roof. In the winter your warm indoor air rises and will leave through the attic if it s not properly insulated. Don t use spray foam to fix a roof leak. In addition to installing the foam board on the underside of the roof deck you can attach it to the bottom edges of the rafters in the same manner you would hang drywall.

Is this a great room with a cathedral ceiling or an attic space with a floor. These circumstances cause your heater and air conditioner to work overtime and your utility bills will spike. Do you already have a roof leak. In some cases you won t be able to insulate the underside of the roof itself but rather the attic floor.
