Doran's Roofing reshingled my house in 2007. They were the least expensive of the quotes that I had received, and the saying "You get what you pay for" holds true here. They did all the work in one day, with the last piece being the garage roof in the evening. The shingles on the garage are not in parallel rows, likely due to the low light conditions as they hurried to finish. The clean up was not satisfactory, especially when they did my neighbour's house the next month and a lot of debris ended up in my eavestroughs. They did not return as promised to clean that up. I should advise that I have not had any leaks, so the work is adequate. I just checked the attic (July 2014) and found that they dumped pieces of shingles plus lots of plastic wrapping from the shingle bundles through the vent holes into the attic. If you hire them, make sure to carefully monitor their work.
