Probably have different instructions for different models. All should come with good installation instructions. Basically, you need to go into the attic space and select the spot, between rafters, where you want to install it. Access to electrical power is a consideration unless you choose a solar model. Drive a long screw up through the roofing in the exact center between the rafters. Then go on the roof and locate the screw. You'll have to carefully remove enough roof shingles to cut the hole for the fan. After installing the fan with sealant, you'll have to replace the removed shingles. Be very careful that you follow all instructions with your fan to insure good seal. I would also recommend use of window flashing tape on the top and sides of the fan housing to get the best seal possible. Don't fall off the roof! Then hook up the required electrical wires AFTER insuring that the power to that circuit is OFF.

I have never removed the shingles. As was said above locate the center of the bay . Drive a screw out two feet from the peak. Find it on the roof. Most fans come with a template for marking the siz of the cut. Center the template and trace around it. Cut it out with a sawzall or jig saw. Pry up te shingles around the top half of the hole. Don't remove them just take out the nailsthat hold th m down. Test fit the vent. Slide it up under the shingles abovethe hole. Take it back out and run a bead of silicone around the hole(going under the shingles above the hole. Slide the vent back in and nail down. Drive a nail back in anywhere you took one out to ensure that the shingles don't fly off.

PS If you fall off the roof, try to bounce.

I am very amateurish in this homeowner thing, but I don't like anything on my roof that might leak 5-10 years down the road. Wouldn't it be safer to put a fan in the side of the house just under the peak?

I thought of that too Devildog, but my home is all brick and I didn't relish the thought of standing on a 20' ladder trying to cut through brick and block.Thank you all for your help!
