Good attic ventilation is extremely important in maintaining the conditions of your home. Attic temperatures generally approach the extremes during both summer and winter. During summer, they can get extremely hot while during winter, they can extremely cold. The bad news is that this has very serious implications for the structural integrity of your attic and the roofing in general. If this temperature is not adequately regulated through proper ventilation, these extremes in temperatures will create conditions that will lead to a rapid deterioration of your roofing material. It mostly damages the asphalt shingles of your roof and this will in turn cause leaks and other water-related damages on the roofing. The best way to achieve this is by installing Roswell GA powered attic ventilation fans.
These Roswell GA powered attic ventilators act as the passive ventilation system in the home in expelling hot air or very cold air from the attic. During summer, it will keep the attic cool while in the winter, it will keep it dry thus preventing the formation of the ice dams. The best thing is that they add very little to the home’s energy costs and in fact help you in reducing the costs of cooling as it prevents the over-tasking of the home’s air conditioning system. The procedure for the installation of Roswell GA powered attic ventilation fans is as follows:
- Start by marking the location of the fan. You do this by standing the fan in your attic and then driving a nail through the roof. The nail should be centred between two rafters. Roswell GA powered attic ventilation fans should be placed a third of the way from the peak of your roof in the attic’s centre.
- Take measurements of the diameter of the intake fan that you will install. This will be the opening on the bottom edge which will allow air to be pushed out of the attic by the fan.
- Draw a circle on your roof matching the diameter of the attic fan. Centre it over the nail you drove through the roof in step 1 above. You can draw the circle with a piece of chalk.
- Using a utility knife, cut shingles along the circle you have drawn above. Make use of a prying bar to pry these off the roof.
- On the inner edge of the area where the shingles were removed, drill a hole. You can do this using a reciprocating saw. For protection, wear goggles when cutting a hole in the roof.
- Get rid of the roofing nails around the shingles immediately. Use a pry bar to lift the shingles and loosen the nails. You can then use a hammer to pull out the nails.
- To prevent leaks, you can apply roofing cement around the hole. You may then insert the attic fan into the hole. The bottom of the fan should be lowered to the roof and pressed against it. The flashing or the thin metal surrounding the fan should be slid under the shingles above the hole you had cut earlier. Screw into place the bottom edge of the flashing. After this, apply caulk on the screws as well as the joints between the flashing and the shingles.
