Stephenson Roofing replaced the roof on my father's house with Certainteed fibreglass reinforced shingles. They explained various options in terms of quality and cost and did not try to oversell extras. They provided a detailed quote that was less than several other major companies contacted proposing similar work. They promised to attend the job promptly, weather permitting, in February, and they did. They estimated it would take 2 1/2 days to complete the job and they were actually done in two full days including a thorough yard clean-up. Disposal bin gone the next working day. The roof looks great. The neighbour even commented how courteous the crew were, apologizing when an errant shingle piece fell in his yard and promising to pick it up.
