Powered roof vents are a wonderful and underutilized tool for the homeowner. Attics can get incredibly hot and stuffy during the summer months. Most homeowners do not consider this to be much of a problem, but a few issues can crop up if your attic is not properly ventilated. Vents suck moisture from the home, so vents help prevent the proliferation of mold and mildew. Wood rot is a fungal infection that plagues homeowners everywhere, and these vents slow its growth. So even if you aren’t in your attic very often, powered roof vents greatly impede costly and negative situations in the future. Below are the three biggest mistakes homeowners make when installing powered roof vents.
Powered roof vents can be incredibly effective, but you need to put them in the right place. The guideline suggests that you need one powered roof vent for every 150 square feet of space. You need square feet, not cube feet, so all you need to measure is the floor. Multiply the length by the width to get your number. If you have an irregularly shaped attic, or your square footage is slightly off, don’t worry. An estimation of the floorspace or a number within a reasonable measure of 150 feet still mean that a powered roof vent is a good idea. Make sure that the vent is placed at least two feet below the ridge of the roof. Should your attic be larger than 300 square feet, ensure that your powered roof vents are spaced out evenly. Also, don’t place a roof vent above a rafter.
Just having the powered roof vent is not enough. You need to have a pencil, a utility knife, a pry bar, a saw, caulk, a hammer and nails, and a broom. The pencil’s use comes in marking where exactly you want to cut. Measure twice and cut once, as the old saying goes. The utility knife comes in when you need to cut the shingles loose so you can apply the powered roof vent. If any of the shingles are nailed to the roof, the pry bar comes in handy for removing them. A saw comes in handy when you are cutting the hole where the vent goes, especially as you need precise cuts. Caulk is useful when you are attaching the flange to the roof, as well as when you are nailing the vent down. No one likes a leaky roof. A hammer and some nails are necessary for firmly attaching the vent to the roof. Finally, you need to sweep the roof of all the debris once you are done.
You can always use an extra set of eyes or an extra pair of hands when doing handy work around the house. A fall from 15-20 feet up is not going to kill you, but it can break a bone, so having someone steady the ladder is vital. You are going to have to loosen a bunch of shingles to install these vents, so having another person there expedites the process.
