Start by gathering your supplies: roofing caulk or sealant, a caulking gun, putty knife, and possibly roofing cement or patch material if you spot cracks. First, inspect the area around the vent for damage or loose shingles—these should be fixed before sealing. Clean the vent base and the surrounding roof surface so the sealant will adhere properly. Apply a thick bead of sealant along the vent’s edges, making sure to fill any visible gaps. Smooth the sealant with your putty knife for maximum coverage and a clean finish. Allow it to dry according to the product instructions, then check for any missed spots. For vents with flashing, seal beneath and along the upper edges for added protection.
