Report
It was told they are not reputable but thought I would give them a chance.They suggested adding drip edge on flat roof after fascia is done. I later learned from reputable company Sanderson this should have been done when roof was being installed. Called Mongeon back and he said they would have to charge me to install it and reseal the edge. He had originally discounted $200 from invoice. I called him back to do the work and he told me that we were fine and hung up. Pay a little more and hire a reputable company
