Early last year I found a shingle in my garden and believed it came from a specific section of my roof as it appeared from the ground that one was missing. In the summer a roofer came out and said that I was correct and there should new a shingle there. ( they were quoting the job) today my property manager sent out Ontario roofers and they said there's nothing wrong with my roof and I'm not missing any shingles. He even showed me photos to ease my mind. These guys are honest unlike the other company that came out previously. I'd call them in the future if I have any roofing needs.
