If your house lacks proper attic ventilation, then your roof is more likely to decay, condense excess vapor, develop mildew. Installing vents and soffits on your attic will lower your electricity bill, prevent the formation of ice dams, and preserve overall health of your roof.
How can you improve the air circulation on your attic?
You are presented with two options: hire a professional technician or do it yourself. Either way, you have to make sure that it’s done correctly by either hiring a certified handyman or by sticking to the rules and plans if you’re doing it yourself. If you don’t do a proper job, you’re likely to achieve the opposite result. We’re going to focus on the DIY part since handymen don’t need much advice.
Determining whether you need attic ventilation
If you can’t find any vents or soffits on your roof, including the ridge vent on top – then your house needs ventilation. Next signs are a hot ceiling in the Summer, condensation and mold on rafters, and ice dams.
What you’re going to need
Square vents and soffits are the easiest to install, so we recommend using them. Soffits are installed in the eaves, whereas vents are recommended closer to the top. The general formula for quantity is one sq ft of vent per 150 sq ft of the roof. In addition, you’re going to need various matching screws and nails which you can find at your hardware store.
Installing attic vents
– The first thing you need to do is to draw a sketch and mark the places where you’re installing the vents.
– Next step is to cut the shingles or remove tiles. After that cut a hole in the roof sheathing with a jigsaw.
– The third part is removing any debris and sliding the vent it.
– The last thing you need to do is to apply roof cement, and secure everything in place with screws and hammers.
The same thing applies to soffits too except they are installed in the eaves, and you need to add baffles for the air to get past the insulation.
Remember, safety is the most important so never do roof maintenance on a wet or a hot day and secure your equipment tightly so that it doesn’t slide off the roof and possibly hit someone beneath.
