Improperly sealed vents can lead to water damage, insulation issues, and even mold growth. To caulk roof vents for maximum protection, start by thoroughly cleaning the area around the vent and removing any old, cracked caulk with a putty knife. Choose a high-quality, exterior-grade silicone or polyurethane caulk that remains flexible in extreme weather. Apply the new caulk in a continuous bead along the vent’s edges and any overlapping seams, ensuring there are no gaps or bubbles. Use a caulking tool or your finger to smooth the bead, pressing it firmly into the crevices for a watertight seal. Allow the caulk to cure as per the manufacturer's instructions before exposing it to rain. Regularly inspect your roof vents and reapply caulk as needed to maintain effective protection.Tips 1:As a designer, I always recommend considering how your roof’s details interact with your overall home aesthetics.
