What you Need to Know About Minneapolis Residential Roof Ventilation Systems

What is a roof vent and why is it necessary?

Roof vents allow moisture to escape while preventing the growth of mildew and mold. In Minneapolis, MN, the weather through the year can change drastically. These vents help in keeping the wood rot from developing in the household. Roof vents are made of metal or plastic. We’re going to talk today about the steps that roof installers take to ensure correct roofing vent systems run smoothly.

Ventilation is necessary for every household, as a risk of the household being filled with harmful gases and irritating smells is high. Here are some steps that you have to follow when installing a ventilation system in your house or apartment:

Step 1

Work out the number of vents that will be required. Start by measuring the square feet of your attic floor. 1 square foot should be installed for a single section that measures 150 square feet.

Step 2

Decide the place where the vents will be placed. Avoid placing them over a rafter, as that may cause them to slip. Make sure that the roof vents are spaced evenly and try to position them at least 2 feet below the ridge.

Step 3

Mark the specific place where you will install your roof vents. Poke a nail on the backside of the roof and use the nails poking out as a center point to measure the dimensions.

Step 4

Take off the shingles lying in the place of the roof vent. A pry bar is used to pull anything that remains.

Step 5

Use a reciprocating saw to cut away the area that is marked. The size of the hole should be similar to the aperture in the roof that will be used.

Step 6

Lose the surrounding shingles. Take out the tops and sides of the shingles that are lying around the cut hole.

Step 7

Place the caulk on the flange of the roof vent. Flanges usually extend outwards, towards the lower side of the roof vent. They provide protection for any leaks that may occur between the surface of the roof and the vent. Make sure the caulk is placed on the roof vents flange.

Step 8

Inserting the flange is a tricky step. Start by slipping the side and back parts of the flange of the roof vent below the loosened shingles. The front part of the flange should be allowed to lie over the shingles.

Step 9

Make the roof vent secure by hammering nails in the roof vent’s flange. Place the caulk around and on the nails.

Step 10

Apply roofing cement on the sides and back of the flange of the roof vent and the underside of the detached shingles. Be careful not to apply so much pressure on the shingles or there is a risk that you will damage or bend the flange.

Step 11

Continue, by installing the remaining roof vents. The same process will be repeated for any other roof vents that you may want to install.

Step 12

Now that you have successfully installed the roof vents, clean your roof by disposing of the leftover materials. A brush or a broom can be used to clear out any dirt off the roof.
