During a unusually intense downpour in the spring, we had a massive leak from a badly done roof replacement the previous fall. The charismatic young roofers who had given us such a great deal on the new roof were nowhere to be found - their number was out of service. My mother had hired MM Roofing in the past and recommended them highly, so I gave them a call. Doug of MM came out on short notice and identified the problem: the flashing where the lower roof met the house, and around the chimney was improperly done. His explanation of the problem and proposed solution was professional and knowledgeable, and allowed me to clearly understand the situation - as well as why and how the less experienced contractors had failed. Doug rebuilt all the flashing, redid part of the roof and added missing drip edges. The fee was reasonable considering the circumstances, and I was very impressed with his workmanship. The way he solved the unique problems in the roof's complex angles was a thing of beauty and worked perfectly. One of the most professional contractors I have ever dealt with. Highly recommended.
