"Overall, Certified Incorporated did an excellent job of removing and replacing three different parts of the roof, including some new gutters, of a very old row-house in Washington DC: the mansard, porch roof, and garage roof. For this work I give Certified an “A” overall. It took Certified about 5 work days to complete this work. Despite some setbacks and delays due to rain, very cold weather, and the Christmas holidays, Tom, Javier, and his crew scheduled these work days efficiently to complete the job as quickly as possible taking into consideration the impact of weather on the installation of the different roofs. (Apparently TPO roofs are recommended to be installed in weather above 40-50 degrees.) Given the winter weather conditions, Certified got the job done within about a week of its original scheduled completion date. In addition, I appreciated that Certified does not take any deposit or payment until they complete their job to the customer’s satisfaction, which demonstrates that Certified is dedicated to completing its work quickly and confident about the quality of service it provides. I highly recommend Certified for high quality professional roofing work. On the mansard roof, Certified’s Javier led the work (with Orlando), completely pulling out all of the old shingles down to the wood and replacing the rotted wood on the dormers and around the gutters. Javier was amazing—I now call him Superman: he worked in very difficult situations and extreme cold weather from 8:45am to about 5-6pm (after sundown) to get the job done meticulously in three days with short breaks for lunch. The mansard roof and dormers are better than what I expected. In addition to the high quality shingles, they carefully added a winter guard below the shingles and flashings on the dormers and along the outer walls. I feel very confident about the integrity of the mansard roof and all of the gutters of my row-house. When the work was completed each day, all of the roofing materials and debris were placed neatly in a pile, which Certified hauled away when it completed all of the work. On the garage and porch roof, Certified recommended the TPO roofing system. This work was delayed a few days due to cold weather, until we had weather that was in the 40s and 50s, which went into the holiday season—Certified’s crew worked on Christmas Eve to install the TPO roof and the day after Christmas to put in the gutters. One issue that arose was that during this period the main foreman for TPO roofing was on vacation, which was an issue since 9 members of the crew seemed to show up without any obvious manager and I had a hard time finding someone who would communicate the work they were doing and issues that may arise. This caused problems on my old porch roof since the TPO roof was installed on top of my old gutters, which were supposed to be replaced—I think it would have been easier to pull out the old gutters when the old roof was taken out and when the old gutters were exposed. On the next work day the crew that came in to put in the new gutters had some difficulty pulling out the old gutters around the porch roof that had probably been there for a 100 years and now also had to deal with the drip edge on top and the delicate rafters below. That said, this is an old house and probably a unique situation and I called Tom to raise these concerns and he did respond by sending over Javier to discuss the impact on the porch roof. Certified managed to do an excellent job putting in new gutters after a painstaking effort to remove the old gutters. I thought the gutter installers were very skilled in their craft. Ultimately, I was very satisfied with the professional work that Certified employees provided and I highly recommend Certified for shingles, roofing, and gutters."
