Step 2: Drill a pilot hole wherever you want the attic fan installed
That way, when you do go up to the roof, later on, you’ll know exactly where to install. Make sure that the pilot hole is at the center of two rafters. With this technique, you can guarantee stability. Also, remember to make sure that your chosen attic fan will fit your area. You can check the manufacturer’s specs or use a tape measure to determine how big your fan is. This is similar to how you would ensure you have a level floor.
Wear protective gear.
Before going up the roof, it can be helpful to use protective clothing like a hard hat, well-fitting gloves, and boots with good traction. Also, it can be constructive on your part if you can get someone to assist you in the process for when you move up to the roof.
Step 4: Mark the diameter of your fan
The middle of the circle should have a pilot hole bored into it. Then climb up to the roof and use a piece of chalk to produce a marker around the pilot hole.
Step 5: Cut out the circle
In this part of the process, you can use a reciprocating saw to do the cutting.
A reciprocating saw is a portable electric saw that includes a blade that can cut into and out of a surface. To start, use the pilot hole you drilled before. Then, cut out the hole by following the line you drew with the saw. Finally, you can remove the cut-out of the wall or the roofing piece from the hole and discard it.
Step 6: Remove the shingles
To move the flattened edge that protrudes off the construction of the attic fan. Check between these shingles and the roof below them to loosen the shingles. It is also essential to remember to remove any nails or staples with the pry bar while loosening the shingles.
When this is done, you can slide the body of the attic fan right over the hole and fit the flange under the shingles.
Step 7: Fasten the attic fan
One effective way to do it is to screw the corners of the flange into the roofing surface. You can start with the bottom two corners in this regard.
You can find two screw holes at the bottom edges of the fan’s flange, one on each side of the blade. The attic fan will be secured to your roof by screwing the flange into place. But before screwing them into place, check if the edges of the flange are appropriately aligned with the shingles.
Step 8: Apply adhesive
Building materials such as roofing adhesives are strong enough to hold objects in place. To reinstall the unfastened shingles, lift them up and spread enough roofing glue between them and the fan’s flange. To reconnect these shingles again to the roof, push them firmly into the adhesive with your fingers.
You can find roofing adhesives in almost any hardware store.
Step 9: Mount the thermostat
The attic fan’s thermostat regulates power use. Locate a rafter that is near to your fan. Then you can screw the thermostat into it. Once you’ve returned to your attic, you have finally installed your attic fan.
In conclusion, while installing a fan isn’t exactly a walk in the park, it’s a pretty achievable thing to get done. At this point, all that’s left to do is to do the wiring for your attic fan. We recommend you hire the service of a professional electrician near you to do it for you.
