I needed repair work for a roof "valley" and for flashing around a chimney on a '50s-style ranch house. Mr. Matlock was quick to respond through "Thumbtack" with an offer to come take a look and provide an estimate. He was punctual and kept in good touch with arrival time, etc. We took a look together and he identified and clearly explained what would need to be done. He promptly provided a detailed written estimate by email, and at my request, a similarly detailed estimate for a whole roof replacement.
After crunching numbers, I opted for just the repair, which was quickly scheduled. Mr. Matlock and his crew of two arrived before 8 AM and promptly got to work. The valley repairs were a little more extensive than initially anticipated, and he showed me where fascia and joist had rotted, etc. and how he would repair those as well. I was impressed especially with the chimney work, which included building a "cricket" -- a little doghouse-shaped bump behind the chimney that diverts snow and water. They finished a bit after 6 PM that day, and cleaned up thoroughly. The following evening we had a heavy rain and I was pleased not to have leaks anymore.
In summary: prompt, courteous, detail-oriented, great at communication; I recommend his firm.
