Attic Super Hot In The Summer

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 super hot in the summer.

Not the overabundance but the lack of insulation in the attic. 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. An unventilated attic can reach 150 degrees in the heat of summer 50 degrees higher than it should be. A thick insulation between 14 to 18 inches will help reduce heat from entering your home.

A hot attic is bad for several reasons. Another reason your attic is so hot is because of insulation. Not only will the attic heat up but if the floor of your attic isn t insulated properly that heat will come right into your home. During the summer heat a poorly insulated attic will allow heat into your home.

Your air conditioner will have to work harder to keep your home cool which means higher energy costs for you. And it can cause your air conditioner to work harder than it needs to and send your energy bills soaring with the temperature. High temperatures inside your attic shorten the life span of shingles. Excessive heat deteriorates items.

An overheated attic can bake asphalt shingles on the roof and cause them to deteriorate. When it s hot outdoors it s hotter in your attic. Summer attic air temperatures with reflective roof peak at or slightly above outdoor air ambient. Damaged insulation will allow hot air to leak into your home during summer causing inadequate temperatures even with ac working overtime.

Within the attic insulation is a must.
