"not that great. basically paid $99 to get an estimate. included cleaning roof and minimal repairs. took a while to get appointment, and then when they came, they didn't even do the work! gave a really big estimate and then re-seheduled to have someone else do the work. they wouldn't totally replace the roof, gave different estimates to repair, I went with a different company to do a full roof rplacement."
