We bought a home that has an existing roof warranty with Collum Roofing, I called over a week ago to request someone to come out and look at the leak in our roof. The receptionist who answered the phone told me - over the phone - that our leak wouldn't be covered under warranty. SIGHT UNSEEN. Even if this is true we still need someone to fix the leak and might have hired this company to fix the roof on our home and our rental property, but as every other yelp review for Collum has assured, no one will return our phone call. I don't understand how they are still in business.
