How Hot Does An Attic Get

Ideal attic temperatures shouldn t be more than 10 to 20 degrees hotter than outside temperatures.

How hot does an attic get. The thermostat will usually start at 95 degrees fahrenheit which is the temperature that the attic fan usually starts at. Depending on the humidity. But by adding powered attic fans you will draw more air into the attic. Having a properly vented attic is the best way to keep attic cool because it allows the hot air to escape during the summer.

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. The heat temp is one thing but the heat factor would be another. 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.

I have large attic with ridge vents and screened vents at either end of the attic to maintain air flow. I recommend you put a digital thermometer in yours and get an exact reading. Not the overabundance but the lack of insulation in the attic. In addition hot air in your attic could increase moisture levels which could result in wood rot and mold growth.

Another reason your attic is so hot is because of insulation. Using insulation only keeps the attic s heat from traveling through your home. 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. Within the attic insulation is a must.

If hot air is allowed to sit in your attic it could overheat the shingles on your roof and cause damage. Hang pencil and paper next to the thermometer and record the outdoor and attic temperatures. I have a shop in my attic for some of my hobbies and it get s very hot in the summer.
