Should I Insulate My Attic Roof

Radiant heat from the sun beats.

Should i insulate my attic roof. The technically correct approach depends on a number of factors. When you have warm insulation the attic space is kept warm in the winter as the heat from the furnace can reach it. If you d like to finish your attic you will need warm insulation. If your attic is often used or perhaps you plan to convert it in the future you will need to insulate the inner surfaces of the roof.

Insulation roofing there are various factors that affect how often a home s attic insulation should be replaced. For a correct approach an inner roof lining is required. Home ceilings are usually insulated in order to seal off the extreme temperatures in your attic. If you decide to insulate at the roof level then that is a decision to bring the attic into the conditioned space of the house so you re correct the gables would be sealed up and you keep a clear channel for air between the insulation and the roof deck.

You also may need to insulate at the roofline if you live in a hot and humid climate. If your attic is usable space but not lived in then you won t need to insulate the roof rafters as long as the ceiling floor that separates the roof from your living area below is insulated. Plan to pull up the flooring and layer new insulation on top of the old. After this amount of time insulation begins to peel away from the walls and degrade.

Warm insulation is installed on the underside of the roof deck at the top of the attic just below the roof decking. Whether or not there is an inner roof lining and the total thickness of the roof structure. But if the floor is covered in plywood you can t stuff enough insulation beneath it to do the job sufficiently not even in warm climates.
