My Attic Gets 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.

My attic gets hot in the summer.

My idea is to vent the build up of hot air that has risen to the ceiling in the hotspot rooms into the attic so that air from cooler parts of the house can move in. These powerful exhaust fans actually pull the conditioned air out of the house and into the attic. Dark roof shingles absorb sunlight and convert that energy into heat. Within the attic insulation is a must.

An unventilated attic can reach 150 degrees in the heat of summer 50 degrees higher than it should be. Get creative with your roof. The summer heat can seem pretty unavoidable but it shouldn t be invading your home. Many people think that the way is to add powered attic fans to draw more air through the attic.

In addition hot air in your attic could increase moisture levels which could result in wood rot and mold growth. 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. An attic in the afternoon in the summer can be 120 to 140 degrees and some even hotter. Unless your roofing system has insulation on the roofing deck and is designed without ventilation your furnace should not be heating your attic.

Hang pencil and paper next to the thermometer and record the outdoor and attic temperatures. And it can cause your air conditioner to work harder than it needs to and send your energy bills soaring with the temperature. Having a properly vented attic is the best way to keep attic cool because it allows the hot air to escape during the summer. The consensus seems to be that if you have the maximum amount of insulation in your attic floor for your area lowering the temperature of the attic by 10 or even 20 degrees will have a minimal if any impact of actual heating and cooling costs.

An overheated attic can bake asphalt shingles on the roof and cause them to deteriorate. Low cfm similar to a bathroom vent 300cfm and only in the hot spots basically by adding an inline ducting fan to the return ducts for the hotspot rooms. It s only natural that your attic will heat up as a result. In most cases this causes more problems than it helps.

Poor insulation is usually the culprit although if you enter the attic on sunny winter day your attic space can be warmed by the sun more than your furnace. Another reason your attic is so hot is because of insulation. 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. Not the overabundance but the lack of insulation in the attic.

If hot air is allowed to sit in your attic it could overheat the shingles on your roof and cause damage.
