Install Aluminum Roof Vents in 3 Steps
Aluminium roof vents can be installed in roofs of any age, and they help to prevent moisture from being trapped in the attic. Moisture in the roof area can cause damage to the house’s structure. Roof vents also allow hot air to escape through the roof without it needing to create air vents in the rest of the house—saving you energy in the long run.
Varieties of Roof Vent
There are different types of aluminium roof vent, all of which provide different levels of roof ventilation. Gable vents are the traditional style of vent: triangle shaped vents that can be put into the gable areas right under the peak of the roof. Air does not circulate very well with this kind of vent, and they have been replaced by more modern options.
Ridge vents are installed directly at the peak of the roof; they replace ridge shingles, and allow air to escape from the very top of the roof; these type of vents are considered very effective.
Aluminium roof vents include a screened panel which keeps pests out, and an aluminium panel which has holes punched in the face; this creates a more efficient air flow. Aluminium roof vents are recommended, as they don’t rust, and can be relied upon even during the wetter months.
Installing Aluminium Roof Vents
First, remove any old vent covers from the attic, as a good will create air flow.
Cut holes of a rectangular shape into the soffit of the roof. For every 300 square foot of roof, you will need 1 square foot of vents, so more vents might be in order. Measure the size of the vent, and then cut a hole in the attic wall for the same size, using a jigsaw drill. Crisp corners are vital if you don’t want it to appear as an amateur job.
Screw the vent into the hole which was cut, and then secure the vent in the hole by screwing it down. Ensure that the wood quality is good enough to hold the screws.
Install baffles in the rafter cavities in order to keep the air space clear.
Cover the entire area in caulking and insulation such as weather stripping in order to prevent leaks.
Using Aluminium Roof Vents
An urban myth suggests that it is necessary to put insulation inside air vents during the winter to prevent them from sucking out hot air. In fact, it is more necessary to allow ventilation in the roof during winter, when water vapour can drift up into the loft space, and condense upon rafters and the underside of the roof. Moisture needs to be allowed to escape, even during the coldest of winters, otherwise it can encourage mold, and also lead to wood rot.
In addition, aluminium roof vents do not extract warm air from the roof during winter; in fact, if there is inadequate ventilation, the heat in the attic can be significantly higher than either outdoors or downstairs.
