A ridge vent is essential to roof ventilation. Roof ridge vents allow circulation of fresh air within the attic. The presence of ridge vents is useful for extending the durability of roofing materials and elevated rafters, which tend to be damaged by the internal heat. Adding a ridge vent may seem daunting to many people, but with some basic guidelines and useful tips ridge vents can be installed without any concerns.

Step 1—Remove Shingles

Peel away the shingles from the ridge cap of the roof with a flat bar, saving as many shingles as possible for later use. If the ridge ends at a chimney or a wall, it is advised to leave about 10 inches of shingles.

Step 2—Make Hole

With a chalk line, make a 7/8-inch long line, extending downward from the ridge board. Use a tape measure to set your saw’s depth. Cut the roof sheeting using the circular saw until the edge of the roof-sheeting boards is visible.

Use a utility knife to remove the shingles and tarpaper. Along the chalk line, saw away both sides of the roof peak. Use a chisel to sever the wood that hangs from the saw-cut edges. Use a pry bar to remove the sheeting that has been sawed.

Step 3—Install Vent

Place the new ridge vents in the space created due to the removed sheet. Using roofing nails, secure the new ridge vent and replace the old shingles. If necessary, use new shingles.
