<p>The new roof was installed efficiently, but no one from the company actually went on the roof to make sure the roof was installed properly when the workers were done (I had to do that, and found incomplete work), AND, more importantly, I incurred significant costs and some damage to my home because a simple, industry-standard step was not done in the set-up operation. The incomplete work was that some of the vent covers were not completed as agreed to ? I found this out when I climbed up on the roof after the work was done to inspect everything. The company returned quickly to take care of this. I found the bigger problem many months later. To make a long story short, Collins Roofing did not cover the downspout openings (where the downspouts connect to the gutters) before removing the old roof, so lots of roofing debris (nails and washers, pieces of old shingles, the plastic sheets from the backs of shingles) fell into the downspouts. The heavy roofing debris accumulated at the bottoms of the downspouts in the elbows that connect to the exterior drainage lines, and stayed there. These piles of metal, shingle, plastic, etc then acted like beaver dams, catching debris that normally would have flushed out the drainage lines, and the entire drainage system around the exterior of my house became clogged. Eventually, I had overflowing drainage lines around my entire house, causing water seepage in the crawlspace and basement. It took me months, and several expensive plumbing and carpentry bills, to figure out. </p> <p>The saga: After the roof was completed, no one from the company checked to make sure that all was done properly, so I climbed on the roof to check everything, and found several vent covers had not been completed, and so I called to have the work done. The missing work was taken care of quickly, and I thought all was okay. Then, several months later, I noticed that some of my downspouts were overflowing at their bases (at ground level), and several gutters too, every time it rained. (I sweep the roof and gutter screens about six times a year, and remove the screens and clean out the gutters once a year, so this was perplexing). It never occurred to me that the problem had anything to do with the new roof, and I spent many months and over $1000 working with various plumbers and carpenters to try to figure out and fix the problem. The plumbers, who focused on the drainage lines, but could not clear them, suggested I replace all my drainage lines, which would have cost several thousand dollars. The problem got worse. Eventually, a smart carpenter took down a downspout, and found it full of roofing debris. After an unpleasant meeting with Mr Collins, who insisted that a little roofing debris always gets in the downspouts (I showed him the two fistfuls of debris from the one downspout, which he insisted is normal) and that the reason for the overflows was me not cleaning out the gutters. Mr Collins finally agreed to send his plumber over. I spent an entire day working with the plumber, taking down all the downspouts (which the plumber did not want to do, but I insisted), and cleaning out the downspouts and the drainage lines. All of the elbows where the downspouts connect to the drainage lines were completely clogged, and I was the one with a bloody arm up to my shoulder at the end of the day since the plumber would not stick his arm in the drainage lines. (I pulled fistfuls of roofing debris from each elbow). I have asked Collins Roofing to reimburse me for my out-of-pocket costs (for my plumbers and the carpenter, including sanding and repainting the basement wall that was damaged by water intrusion), but he has refused. I have not asked for compensation for the 80 hours or so of labor I expended on this unpleasant project. I checked with several reputable Triangle roofers, and all said that it is a no-brainer industry practice to cover the downspout openings before working on a roof to avoid the damages I incurred. There clearly was insufficient oversight on my roofing project.</p> <br />
