Fix Plumbing Vent Boots

Plumbing vent boots can be all plastic, plastic and metal, or even two-piece metal units. Check plastic bases for cracks and metal bases for broken seams. Then examine the rubber boot surrounding the pipe. That can be rotted away or torn, allowing water to work its way into the house along the pipe. With any of these problems, you should buy a new vent boot to replace the old one. But if the nails at the base are missing or pulled free and the boot is in good shape, replace them with the rubber-washered screws used for metal roofing systems. You’ll find them at any home center with the rest of the screws. You’ll have to work neighboring shingles free on both sides. If you don’t have extra shingles, be careful when you remove shingles so they can be reused. Use a flat bar to separate the sealant between the layers. Then you’ll be able to drive the flat bar under the nail heads to pop out the nails.

Fix The Leak In A Metal Roof

  • Once you find the leak, youll need to clean the area. Remove any loose sealant, caulk, dirt, paint or whatever else you find. To eliminate stubborn materials, use a putty knife or a metal brush. Its a good idea to burnish it with a brass brush on a drill.

  • Use soap and water to get the area as clean as possible. Let it dry completely before doing anything else to it. A full day of drying is a good idea. Make sure to check your local weather forecast before starting this part of the project.

  • At this point youll want to use a sealant. The terms sealant and caulk are often used interchangeably. However, there are differences. “Sealants are designed to seal an interface that is subject to movement,” according to Best Materials.com. “Caulks are designed to fill a gap. Sealants are designed to create a long-term seal that stays intact and prevents moisture ingress and UV resistant. Sealants deal with greater joint movement, extreme temperatures and have very low shrinkage.

  • Cut the width of the sealant tube opening so that it is about the size of the seam. Often this means that youll need to cut the tube near the top. Have a roll of paper towels ready. Get as much sealant into the seam and onto and into the screw holes as possible. Use the paper towels to remove any excess sealant.
