I though I had saved $400.00, but Guildwood roofing failed to notify me of rotten decking and went ahead and placed tiles without repairing the decking. I found this out when I decided to go on the roof after completion. My roof is currently leaking around the chimney due to poor work. I took some pictures before the company owner came to see what the problem was. He denied it was because of poor work. Recommendation go with a reputable company pay the extra money. Did not realize this service was available so that I could warn potential customers.
