We got two estimates for a leak just above our bedroom. McNabb Roofer guy tells me the slope of the roof is the problem. Apparently not enough slope. Go figure! And the shingles in the section need to be replaced and and basically redone. Estimate of 950+ depending on whether the board underneath needed repair. I call another roofer. In 15 minutes, they had it fixed for 200 bucks!. Comes down and shows me a picture of where two golf balls had hit our roof and created holes. The golf ball holes were the cause. I find it amazing that the roofer did not find these holes right above the point of the leak.
