This house was built in 1914 and it had some structural issues with the roof among other things. From the exterior it dipped in the middle, so there was an obvious problem. The customer wanted to find a company to handle the structural part of the roofing project and take care of the roof, so he chose us.
First, we stripped the left side of the roof; the shingles, flashings, backing paper, and decking. Our guys had the house open to the attic, so we had to be very conscientious of the weather.
The rafters were 24 on center, which does not exactly pass code now, so we had to fix it. We did this by sistering what was there and installed new rafters, so it was more like 16 on center, or 16 inches from one rafter to the next one. This was a good foundation to support the roof. At this time, the flashings on the chimney were grinded out, so we could replace it.
Next, we installed all new sheathing on the left side of the roof and covered it quickly with the roofing materials. We used 8 inch flashing, 6 feet of ice and water shield (Certainteed's Winterguard), and 30 lb. felt paper (Roofer's Select) for the underlayment. For roofing shingles we used Landmark Premium shingles in a Harvard Slate color. These carry a 50 year warrantee because they are very thick and durable. The customer had no ventilation at all, and no soffits on the house. With no soffit, it makes it hard to get lower ventilation, but we solved the problem with the Edge Vent system. The Edge Vent allows air to go into the attic from the lower part of the roof. It works great in combination with a ridge vent, which we also installed on the top of the roof. We used the ShingleVent II® by AIRVENT for this.
The last part of the project was to replace all the gutters. We used white, seamless aluminum gutters and downspouts. There were a few angles on the house, which made things tricky, but we were able to get the water flowing in a good direction for the house. Overall the customer was very pleased with the outcome of his project. He commented on how straight the roof line was after we supported it properly. He has recommended us for other projects to his friends because he thought our overall service was professional and we got the job done properly.
