Michael and Zach came exactly on time. Before starting the work, Michael explained to me what they are going to do. As explained they got on the roof, inspected the roof, fixed loose nails, caulked joints where necessary, cleaned gutters. He emailed me pictures of his work. There was a leak in the garage. Michael found the source of the leak and fixed it. He also promised to come back and extend the downspout, Both these gentlemen were very polite, knowledgable and hardworking. I recommend them for any roof work.
