In short, the guys came over, slapped on a bucket load of tar (some black sealant) around where my chimney and roof meet and left. That cost me $400! I called a few guys for some estimates prior to contacting Mr.RoofRepair and they recommended that I buy some tar from HomeDepot and slap it on myself. I wish I had listened to those guys, because MrRoofRepair did the same thing for $400.
But in contrast, the report they sent was very thorough and informative, and I'm wondering if they book $400 appointments just to take pictures and produce reports. The estimate for "doing it right" was high in comparison to other contractors as well. I wouldn't be so critical if they had actually fixed my problem. I could still hear drops of water on my gas fireplace, so obviously their "quick fix" did not work and I'm out 400 bucks, but the report sure is pretty!
Oh yeah, and they left a caulking-gun on my roof. What if that had fallen on someone?
Anyways, I definitely don't agree with their business model.
