Many people believe that a roof vent’s sole purpose is to release sewer gases outside the house. However, its primary function is to facilitate proper drainage and sewer system operation by allowing air to flow into the sewage system and balancing pipe pressure.
Despite their importance, roof vents can often lead to issues like roof leaks, commonly occurring at the roof vent pipe collar. Fortunately, resolving this issue is relatively straightforward.

While working on the roof, make sure to have a sense of safety precautions. Trim the rubber boot with a cutter until it perfectly fits over the previous rubber boot. Make sure everything is aligned and looks great.
- Get the Rubber Boot Sealed in Place

- Clean the Excessive Silicone Sealer
Since you put in many sealers, it will squeeze out while you apply the new rubber boot. Use a cloth to clean up the excessive silicone sealer and smooth it out. Now, the roof vent repair process is done. The seal is perfectly tight. Either rainwater or debris will not be able to get through it.
