How to Fix A Roof Vent
You might want to check for cracked housings on plastic roof vents and broken seams on metal ones. You might be alluded to throw caulk at issue, but that solution won’t last long. There is no fix for this other than replacing the broken vents. Also, look for pulled nails at the base’s bottom edge. Replace them with rubber washer screws.
Extract Nails Beneath the Shingles
You can extract nails beneath the shingles on both sides of the vent to pull it free in some cases. There will be nails into the top of the vent as well. Most of the time you can also work those loose without removing shingles. Screw the bottom in place with rubber-washer screws. Squeeze out a bead of caulk under the shingles on both sides of the vent to hold the shingles down and to attach a water barrier. That’s much effortless than re-nailing the shingles.
