Then, use a circular saw to cut into the area you marked, and squeeze out a line of caulk around the edges of the hole to help the vent stick to the roof. Finally, position your exhaust vent on top of the hole, and nail down the corners to ensure that it stays in place. To learn more, like how to blend the vent into the rest of your roof, read on!

Go into your attic and look at the area where you plan to install your soffits. Move any insulation around the outer edges and make sure the area is clear of any electrical components or wiring so you can work safely outside with your power tools.

If there are wires, find a different spot to install your soffits. Look for nail lines or seams in the paint since these indicate where a rafter would be in your attic. Use a pencil and a straightedge to draw the rectangle directly onto the bottom of your overhang. This will be where you put the soffit vent. Have a partner hold the ladder steady so you can work safely. This way, you can easily trace around it and your vents will be straight. Drill holes outside in the corners of the rectangle.

Use a drill bit large enough so that you can fit your saw blade loosely inside the holes it makes. Drill the holes in all 4 corners of the rectangle to relieve some of the pressure from your saw. Cut out the rectangle using a jigsaw. Put the blade of the saw through one of the holes you just drilled.

Turn on your saw to a medium speed and slowly follow the outline you drew on your overhang. Use wood screws to hold the vents in place. Hold the soffit vent over the opening with your non-dominant hand and use a drill with a screwdriver bit to secure it. Start with the corner screws before adding the others. Place soffits every 4 ft 1. Measure out the distance between from the soffit vent you just installed to add more.

You should have 1 square foot 0. Repeat the process for each vent you want to install. Place a layer of window screen inside your vents to keep out rodents or insects. Method 2 of Drive a nail through your attic to mark where you want your vent.

Go into your attic and find a spot at least 2 feet 0. Use a hammer to pound a nail through to the roof. The nail will either visibly stick out from the roof or raise shingles so you know where it is. Clear the shingles in the area to make room for the vent. Get on your roof using a ladder and locate the nail.

Use a claw hammer to loosen and remove the shingles around the nail to clear a space equal to the opening on the bottom of the vent. Otherwise, cut out the shingles using a utility knife. Otherwise, hire a professional roofing service to come install the vents for you. Use a circular or reciprocating saw to cut through your roof. Set the saw depth so it only cuts through the top of your roof and not any rafters.

Turn the saw on and follow along with your outline until the square is completely cut out. Lift the boards out or push them into your attic to throw away later. You can saw through your shingles and roofing at the same time if you have a roofing cutting blade for your saw.

The flanges on your vent should slide underneath the surrounding shingles easily. Place a layer of roofing tar or caulk around the hole and press the vent down. Use a caulk gun to squeeze out an even layer of the adhesive around the edges of the hole. Set your vent on top of the hole so it lines up and press it down so it adheres completely. Secure the vent in place with nails. Nail down the corners of the vent first to keep it in place. Glue down shingles to cover the bottom of the vent.

Press new shingles onto the caulk and use nails at the top of each shingle to fully secure them to the roof. Cover the entire flange with shingles to integrate it better into the roof. Method 3 of Remove the cap shingles from the peak of your roof. Get onto your roof using a tall ladder and climb to the top. Pry up the shingles along the top of your roof using a claw hammer. Set them aside so you can use them later instead of throwing them away.

Push the circular saw in a straight line across the entire peak of your roof to make a slot for your ridge vent. Cut the slots according to how you want the vent. Set the ridge vents on top of the slot. Use enough vent pieces to fill the length of the slot you cut. Center the vents on the peak of your roof so the sides of the vent lay flat on the roof.

If you need to cut the vent to fit at the end of your roof, use a utility knife to make it flush with your home. Hold the vent piece in place until you can nail it down. Use ridge vents meant for the pitch of your roof. Nail the vents to secure them in place. Use the pre-drilled holes in the vents for your nails.

Make sure the nails are long enough to go through the vent and into your roof. Drive them in with a hammer so the vents are tight against the roof. Replace the cap shingles on top of the ridge vent. Layer the cap shingles on top of the vent and nail them through your vent to keep them in place. Did you know you can read expert answers for this article?
