We hired a roofer after getting two estimates. The first estimate was a little lower, but the representative from the second company pointed out that the first company was likely going to charge us extra as they went along, per the wording of their contract, for more material possibly needed. He assured us that would not happen with his company, that the price he quoted us was the price we would pay--half up front, and half at the end of the job when we were satisfied. We signed essentially a blank piece of paper, as did he, with the total dollar amount agreed upon on it, as well as the dollar amount we were giving him up front in credit card and check, and the other half still owed. We realized after he left he did not leave us any paperwork in the folder that he gave us. He then told us we would be getting on the schedule in a couple of weeks. After several weeks not hearing anything from them, with increasing nervous stomachs and sleepless nights thinking we'd been scammed, they finally put us on the schedule. And finally emailed us a generic contract when we asked for it. After they began work, the representative called to say it would be an additional $1,750 because replacing slate with asphalt shingles, they would need plywood to cover the entire roof. While we understand the need for the plywood, the fact of the matter is, he told us on day 1 we would not have to pay anything extra. That's the reason we went with them and not the first estimate! The job is now finished and we are wondering if we are truly on the hook for that $1750. We never signed anything to that effect, and in fact only told them to go ahead with the project because we thought if we cancelled we would probably never recoup our initial payment.
