There are many methods you can adopt to improve the energy efficiency of your home. Installing a roof vent
for attic ventilation is one such method. Having a roof vent up on your attic will allow air circulation inside the attic, help keep it cool and prevent the warm, muggy summer air from warping and damaging the roof.

You will require a sabre saw, electric drill with bit and white chalk for installing a roof vent
The first step involves selecting the locations where you want to install your roof vents. You have to space out the roof vents evenly, leaving equal gaps between all the vents. You are advised to install the roof vents on the rear roof slope. Keep them at a distance of two to three feet below the ridge line.
The next step involves centring these roof vents on your roof in between the rafters. Take a white chalk and earmark the area for each of the vents.
Now you have to drill a hole right in the middle of the area you had marked out in chalk. Position your electric drill properly on the chalk mark and start drilling your hole. Then you have to position the roof vent through this drilled hole on the roof.
Mark out the vent’s perimeter with a white chalk line. Use the sabre saw to cut out the hole of the vent. Again use your saw to cut out a hole following the chalk outline you just drew. Continue sawing till you attain a hole in the shape of the roof vent.
If there are any roof shingles lying inside that circle you had drawn earlier, saw them off. Use a pair of pliers to pluck out roofing nails embedded inside the shingles top row.
With the help of a trowel, cement the edge of the vent hole with roofing cement mixture. Then you have to push down and position the roof vent base underneath the shingles in the centre of the hole. The last part involves attaching the vent base to the roof using a hammer and two inch galvanized roofing nails. Ensure that the nail is hammered in deeply all the way through.
