What to Look for in Quality Roofer?
If you like what you see, it’s time to verify that the roofer carries workers’ compensation coverage and at least $1 million of liability insurance. Get his agent’s name and proof-of-insurance certificates. Then get an estimate, which should be free. Because roofing is a short-term job, break up the total due into two payments: one-third up front for materials, and the remainder when the roofing and cleanup are done to your satisfaction.
Also insist on a warranty that covers leaks, flashing failure and other labor-related defects. A one-year warranty is the minimum, though two or three years is preferable. These same stipulations should go into the contract, which should also include what type of shingles will be used. Request the highest-rated, longest-lasting shingles you can afford.
Shingle manufacturers generally back their products for 20 to 30 years. Some warranties are void if shingles are put on over existing shingles, so tearing off the existing layer could be required, at an additional cost. Asphalt roofs last 13 years on average, so a 20-year warranty should be fine. Just be sure you get the paperwork and proof of purchase needed to pursue any problems down the road.
