Within the attic insulation is a must. And it can cause your air conditioner to work harder than it needs to and send your energy bills soaring with the temperature. A hot attic is bad for several reasons. The attic is a huge determinant in keeping your entire home cool so the first place to start cooling your home should be the attic.

Summer attic air temperatures with reflective roof peak at or slightly above outdoor air ambient. During the summer heat a poorly insulated attic will allow heat into your home. If the joints in your ductwork are not properly sealed your forced air system can suck attic air into the ducts air that s either really hot in the summer or really cold in the winter. Attic insulation is crucial to home s energy efficiency both in winter and in summer when the temperatures peak so it is very important to know the signs of poor attic insulation.

An overheated attic can bake asphalt shingles on the roof and cause them to deteriorate. Summer attic air temperatures with old terra cotta colored asphalt shingles peaked at 140 to 145 at 18 above the blown in fiberglass insulation layer at the attic floor. If the ducts aren t insulated the ductwork will be at the same temperature as the attic warming your cool air supply during the summer and cooling your heated air in the winter. Excessive heat deteriorates items.

High temperatures inside your attic shorten the life span of shingles. Another reason your attic is so hot is because of insulation. When it s hot outdoors it s hotter in your attic. Your air conditioner will have to work harder to keep your home cool which means higher energy costs for you.

An unventilated attic can reach 150 degrees in the heat of summer 50 degrees higher than it should be.
