Correctly installing ridge vents is an essential step for promoting healthy air circulation in the roof space and preventing serious problems like mold, ice dams, and excessive attic heat. Start with checking that your attic has properly sized soffit airflow openings to facilitate continuous airflow. When there’s no proper air supply, ridge vents cannot perform as intended.
Once you’ve confirmed that the intake is sufficient, outline the ridge’s midpoint of the roof ridge with chalk. With a reciprocating saw, precisely follow this line, excavating the sheathing to establish a seamless vent channel along the full length of the roof peak. Make sure to cut just the outer layer and stay clear of the rafters. Maintain a minimum of one inch of roof decking on the ridge’s perimeter to protect the roof structure.
Once the opening is made, install a ridge vent cap that aligns with your roofing system. Position the vent across the opening and attach via Mundell Roofing Albion Park nails, consulting the installation guide. Make certain the vent is level with the surrounding shingles and aligned straight. Fill edge seams around the sides with roofing cement that is suitable for your shingle type to prevent water intrusion.
Finally, install shingles on top of the ridge vent, laying them in standard pattern to disguise effectively with the rest of the roof. Always check local building codes before starting, and seek expert help if you’re not experienced with roofing. Well-executed ridge vent systems will help your roof last longer and significantly improve your home’s thermal performance.
