I did not have prior experience with Royal Roofing, other than a small emergency job they did on the bay windows, where the rooflet was damaged by a storm, but I did remember the name and the reviews were essentially all positive, so I decided to contract them for roof replacement. Home is appr. 3,000 sq ft with attached garage, and we also re-roofed our small shed and asked them to add insulation in a small area, not accessible through attic.
Samples of shingles were provided ahead of time, so that we could see how they looked in bright sunlight or in lower light. The estimate was detailed and complete, except for front flushing, which I knew would need replacement, but was not included in the original calculation.. Since, I was out of home, but Royal Roofing sent me updates, including about 30 photos, to demonstrate for example that GAF Timberline lining was put in place and that insulation was added. All work was finished in one day (weather was good), with just small tin skirt around bathroom exhaust vents added the next day. They did a thorough magnet sweep around the house, and cleaned the grass to a presentable state. We did find maybe 6 nails later, and small thumb-size pieces of thin transparent wrapping were also common, but I'd say it is the manufacturer's issue that it breaks so easily.
In general, I am very happy about Royal Roofing and the way they treat their customers. Thank you Mykola Maksymchuk, and thank you Lubomyr Seniv.
I only write this review about a month and a half after the job. We are now in heavy rains again and the roof holds just fine and looks just great.
