Solar Attic Fan

Our house gets so crazy hot in the summer and a big part of it is that the attic heats up during the day and remains hot in to the evening. In order to solve at the least one part of our problem. I installed a solar attic fan.

To start with I had to get all my gear up on the roof, which seemed like a simple step, but with a sawzall and the actual fan being pretty heavy, it took some doing. Next I mark the hole on the roof with sharpie. I start the cut by drilling a couple holes on the edge and then using the sawzall to cut out the hole.

 Next I pull up some of the singles so I can slide the unit up under. I finish by using heavy duty roofing adhesive to put back the lifted shingles over the flashing of the unit. Up in the attic I cut free the wire that senses temperature and kicks on when the attic gets warm enough and if there is direct sunlight.

It seems to be doing a pretty good job overall. The attic never gets particularly hot, but the house still gets hot just not quite as hot as before.
