Mark and his people do very poor quality work, they did a poor job on the roof of my house. I have been calling him to fix some issues. they are very unprofessional and do not show up when they say they will. I believe the issue with my roof is that they could not get the lay out right. It is obvious, because all of the cap tiles are short and do not reach under the rake tiles. the valleys look bad because little peace do not plane with the rest of the roof . the valley tiles are also cut at different angles and it looks horrible it looks like a giant "Roof Saw" . I wish I could upload a picture and let those speak for themselves. will end up taking better roofing systems to small claims to get my roof fixed.
