Roof leak at a low slope Valley in West Knoxville. These roofs are about 10 years old and were installed after a hailstorm. The area of concern is a 1.8 to the 12-pitch roof. This section of the roof is lower than the recommended slope for shingles. So one of the solutions that we were advised to resolve this roof leak is a membrane roof over the downward slope area. Membrane roofing is traditionally thought of as a commercial-style roof or a rubber roof. This roofing material will go underneath the shingles on the surrounding slope and cover the flat portions of this roof.

The next solution that we mention will be much cheaper and easier but will not have the same level of confidence for resolving this roof leak issue, that is to caulk all of the shingle unions, caulk the facia returns, and caulk any penetrations seal up everything where the water can spread or leak anywhere on this low slope roofing material. Several people have attempted to resolve this roof leak, and their repairs have not worked yet, but these are two very viable solutions that have a good chance of fixing this problem.

This solution made it very easy to have a roof it stopped leaking.

This project added cost to every unit so that the shingle unions would not leak. This will be a straightforward solution. Hopefully, this resolves this roof leak on this low slope roof after 7 inches of rain. We’re fairly confident that this resolves the problem.

The rest of this project was completed by lightspeed construction installers. We did a great job and stopped the roof leak. It was a terrific project, and the customers were extremely happy because we resolved the problems.
