I found Sideline Construction's Tom Smith at a Rochester, NY home show, about 15 years ago. He had the lowest bid regarding re-roofing a low pitched roof over my bedroom wing. Other roofers stated that they would use roll roofing, but Tom insisted traditional shingles were OK and would look better. (It's so low pitched you can't see the roof unless from uphill or in a tree.)
Well, 2 years later, the roof was leaking into my son's room. The job was "guaranteed" and a crew was sent out to repair or replace the roof. HOWEVER, Tom must have tried to get his insurance company to cover the cost, and found out they would not because even on the original paper wrapping on the shingles, it specifies the lowest pitch that was safe to use them for, and mine was lower. SO he actually ordered his crew to leave after taking off half the shingles and covering it with an old tarp!
I didn't have the money to pay for this all over again, and though I took him to Small Claims Court, it took 2 tries to get any monetary reward. I fortunately qualified for a city grant to get another contractor to replace my roof, but not after a whole summer of running home from work whenever it rained to move the buckets around to catch the leaks.
Tom Smith & Sideline Construction are surprisingly still in business. AVOID!!!
