Our 10 year warranty expires next month and we noticed new staining on a ceiling tile. One phone call to Bob and the problem was addressed. Workers were on site the next day, exactly on time and assessed the problem and repaired it within an hour. They were polite and respectful and explained the issues with cell phone photos so everything was clear and easily understood. This is clearly a firm that stands behind their work. There was no charge even though the leak did not originate from the roof which was intact, but the cement blocks of the adjoining wall.
