How Hot Does An Attic Get

Not the overabundance but the lack of insulation in the attic.

How hot does an attic get. Using insulation only keeps the attic s heat from traveling through your home. But by adding powered attic fans you will draw more air into the attic. The thermostat will usually start at 95 degrees fahrenheit which is the temperature that the attic fan usually starts at. It will help to keep the attic much cooler in the summertime.

Hang an outdoor thermometer in your attic making sure its range reaches at least 130 degrees fahrenheit. Roofing panels can get wet when design or construction flaws allow moisture in when ice dams damage shingles or when strong winds and storms damage the roofing. Having a properly vented attic is the best way to keep attic cool because it allows the hot air to escape during the summer. I recommend you put a digital thermometer in yours and get an exact reading.

Ideal attic temperatures shouldn t be more than 10 to 20 degrees hotter than outside temperatures. Depending on the humidity. If hot air is allowed to sit in your attic it could overheat the shingles on your roof and cause damage. 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.

Hang pencil and paper next to the thermometer and record the outdoor and attic temperatures. I have large attic with ridge vents and screened vents at either end of the attic to maintain air flow. If your attic soars above 100 degrees and reaches the 150 mark its time to consult professionals. In addition hot air in your attic could increase moisture levels which could result in wood rot and mold growth.

The heat temp is one thing but the heat factor would be another. Another reason your attic is so hot is because of insulation. Wet roofing panels have even less of a chance of drying in an unventilated attic when insulation has been applied directly to the underside of the roofing panels.
