Installing a turbine roof vent provides one of the most effective ways possible of keeping an attic or loft cool. In the summer months, the loft area of a house can heat up a lot making the rest of the house unpleasantly warm. This will also make any air conditioning installations work harder, costing you more money to run. They do need to be strategically placed to be as effective as possible and installing them can be difficult. For those who are quite familiar with DIY, however, it is a job that does not necessarily require the help of a professional tradesman.

Step 1 - Preparing for Installation

The optimal location of a turbine roof vent depends on your house. Generally, they are placed on the side of the roof which is not exposed to the traffic. They can be unsightly, so for this reason, you may want to put them in an area of the roof which is not seen so often. To begin, you will need to measure the length and width of the sides of the roof where you are going to install the turbine. If you are going to install multiple vents, you need to divide the lengths that you have measured by the number of turbines which you are going to install. If you are going to install two vents, they should ideally be equidistant from the edges of the roof. A third vent should be between the two. It is also very important to avoid cutting into any rafters as this can damage the stability of the roof.

Step 2 - Cutting the Holes in the Roof

When you have figured out precisely where the vents should be installed, place the neck of the turbine up against the roof inside the attic. Using your marker pen, trace around the edges of the vent on the underside of the roof. Continue by drilling a hole in the center of the marking through the decking, felt and tiles. You will then need to take the vent up to the top of the roof, placing it centrally over the hole you have drilled and cutting around it. You will need to cut the shingles individually after removing them using a hammer to remove the nails. You will need to use the reciprocating saw to cut into the decking.

Step 3 - Installing the Turbine Vent

When you have prepared the surface, installing the vent is perhaps the easiest part of the job. Providing you have done your measurements correctly and prepared carefully for the installation, you should be able to slip the vent through the hole in the roof. Continue assembling the vent as per the instructions in the manual that comes with it. When finished, you will need to make sure that the roofing around the vent is insulated adequately. To do this, simply apply more tar paper around the edges and seal it.
