How to choose a roofer without getting burned
Most homeowners hire the first contractor who answers the phone, which is roughly the same strategy as picking a surgeon from a billboard. A roof is the single most expensive thing on your house, and the difference between a good install and a bad one does not show up for six years.
Start with the paperwork nobody wants to read. Ask for the licence number and check it yourself with the state board — it takes ninety seconds. Ask for proof of liability insurance and workers' compensation, then call the insurer to confirm the policy is current.
Then ask the question that separates the professionals from the rest: what happens when the deck underneath is rotten? A good roofer already has a written per-sheet price for that, because it happens on roughly one job in three.
