My company put a roof on for one of their customers. Luckily the home owner paid me what the company's estimate was due to the house being sold so the lender cut me a check. The home owner is still fighting with them along with my help to get the depreciation back. They also shorted the estimate by 800 sq feet of roof. Upon putting in for a supplement I was told to get a eagleview. That measures the roof by satellite. I did that and now like everyone else has said they only talk to home owners and it's gonna be a couple weeks..it's been a couple weeks a couple times. They are extremely rude and it's obvious they have no concern for their customers or the contractors that do the work.
