Very good company with in-depth knowledge of what they're doing. I am a building engineer for a major corporation and we had several leaks in a building that five other roofers could not solve. I contacted Alliance and they recommended a solution that no one else prescribed. After a full winter and several hard rains, for the first time in years, we are not having leaks. I would highly recommend Alliance.

They applied a roof coating system for our church and were remarkably reasonable with their price. They started the project on time and were very professional. After they finished, we had a problem with the gutter and they fixed it for free. Excellent company.
