Installing a ridge vent is a popular way to let air flow in the attic without ruining the roof’s appearance. It sits along the roof’s ridge and is not much visible.
When installing a ridge vent on a shingle roof, you will need tools like a hammer, a pry bar, and a circular saw. You will also need roofing nails, shingle caps, and caulk. The process involves removing old shingles, cutting the ridge to make an opening, and attaching the vent. After cutting the roof deck, new shingles are installed, followed by the ridge vent. The installation may vary slightly depending on the type of vent you choose. If you’re not comfortable working at heights or with power tools, it’s best to consider professional roofing contractors help.
Step-By-Step Guide on Installing a Ridge Vent On a Shingle Roof
Here is a detailed guide to help you with the process.
Step 1: Remove the Shingle Caps
Start by removing the shingle caps along the ridge of the roof. These are held down by nails, usually two per cap. Use a flat pry bar to lift both the shingle and the nail. Remove the nails and shingle caps carefully. Once they are off, use a utility knife with a hook blade to cut the shingles back about 3 inches from the ridge. Remove any underlayment or felt paper to expose the wood decking beneath the shingles.
Step 2: Cut the Ventilation Opening
Now, you need to cut an opening in the wood decking for proper airflow. You want to create at least a 1-inch gap on both sides of the ridge board (the beam running along the peak of your roof). If there is no ridge board, like in some truss-framed roofs, the gap should still be at least 1 inch from the ridge on both sides. Use a chalk line to mark where you need to cut. Be sure to remove any nails above the cutting lines. Secure the roof decking below with new nails, and use a circular saw to cut along the chalk lines. Remove the strips of wood along the ridge.
Step 3: Install New Shingles
Once the opening is made, you may need to install new field shingles over any exposed decking. Reattach any existing shingles that were cut back earlier with roofing nails. Make sure the shingles are secured along the top edges to avoid any leaks.
Step 4: Install the Ridge Vent (Shingle-Over Style)
If you’re installing a shingle-over ridge vent, measure down from the ridge and mark the recommended distance on both sides. Use a chalk line as a guide, then place the vent along the line. Nail it down according to the manufacturer’s instructions. Once the vent is secure, install asphalt shingle caps over the ridge vent using the specified nails.
What is the best Way to Vent a Shingle Roof?
The best way to let air flow in a shingle roof is by using ridge vents or soffit vents. Ridge vents go at the top of the roof to let hot air out, and soffit vents bring cool air in. This helps keep the attic cooler and stops moisture from building up, which can harm the roof.
How do You Install Shingle Vents?
To install shingle vents, you first cut a gap along the roof’s ridge for the vent to fit. Then, place the ridge vent over the gap and nail it down securely. After that, cover the vent with ridge cap shingles to protect it and blend it with the rest of the roof.
How to Cut Shingles for Ridge Vents?
To cut shingles for a ridge vent, use a utility knife to trim them along the ridge of the roof. Start by cutting a gap where the ridge vent will go, then cut individual shingles to fit around the vent. Make sure the cuts are clean and even for a neat finish.
Conclusion
Installing a ridge vent on a shingle roof can be a bit challenging since it requires working on a roof with power tools. If you’re not confident with heights or handling tools, you may want to consider hiring a professional for shingle roof installation. Keep in mind that a ridge vent works best when combined with other attic ventilation like soffit or gable vents for proper airflow, and it is one of the best roofing materials to allow air circulation in the attic.
