My mother hired a licensed, bonded, and insured roofing contractor to clean the gutters on her flat roof in NY. She was told that she needed a new roof, so the company removed the old roof and installed a new one with SBS black modified bitumen membrane in February 2009. My mom never had any problems with this roof until this roofing company (who has been around since 1921) worked on her roof. Ponded water remains on her roof for more than 48 hours, and this has resulted in paint peeling, cracking, & chipping on the walls, ceilings, and beams to the second floor. There is no attic on this house, and it is approximately 100 years old. My mother still has 7 years left on her warranty, but the roofing company is saying that this damage occurred before they fixed her roof. They insist that the house is very old and out of level, and that they have provided my mother with a water tight roofing system that does not leak, and ponded water is nothing to be concerned about. If the house isn't leaking why would there be dark stains which look like mold/mildew and why would there be damages present now that didn't exist prior to 2009. I am being told by another roofing company that 2 beams on the roof have collapsed. Would a roofing contractor rip off an old roof down to the plywood and install a new roof over it if? I live in Florida, and am trying my best to help my mom with this problem. The BBB has not been of much help. My mom is 84 yrs old, disabled, and lives alone and I feel that she has been taken advantage of not to mention is this house safe for her to live in? Any help will be greatly appreciated. Have loads more photos if needed.
