If the roof on your home has failed prematurely, there is likely a problem that needs to be resolved to protect the new roof. One element that is overlooked and leads to roofing damage is the attic ventilation. If the attic space isn't ventilated properly, it will hold the heat in the attic which will lead to mold and wood-rot – attic ventilation is needed. Here, you'll learn how to install a turbine head attic vent on your roof.

Placement Location

The placement of the turbine will have a significant role in how well it ventilates your attic. The turbine should be roughly 16" from the ridgeline. Locate the rafters by using the stud finder. Mark the rafters. Measure the hole size that you'll need – typically 12-14" – depending on the turbine that you've selected – refer to the instructions sheet if you're unsure.

Installation

Now that you know where the turbine will be positioned, it's time to get to work installing it. Use the jigsaw to cut the hole that you've marked.

Roll up the shingles in the area around where the turbine will be installed. Be gentle with the shingles so that you don't tear them – you'll be able to lay them back into place if you're careful. Place the base of the turbine over the hole and make any adjustments that are needed to create a level seal between the base and the roofing.

Pull the base back out of the hole and coat the underside of it with roofing cement. Don't use too much cement or it'll blister once it's in place. Put the base back in place and press it firmly into position. Coat the underside of the shingles with the roofing cement and lay them back in place, trimming the excess as needed.

Secure the base to the roof with roofing nails and attach the shingles. Coat the roofing nails with roofing cement and seal the inside of the stack where it meets the flashing. Mount the turbine head to the stack and insert the screws that secure it. Coat between the turbine stack and the base with silicone caulk to create a tight seal to keep water out.

This job is simple enough, but if you're not comfortable taking it on yourself, talk with your local roofing contractor for assistance. For more information, contact a company like Advanced Roofing and Construction.
