We just got a leak and have had some folks come out to quote - so far I can only say who I would never recommend and that's Mark Nejmeh at Real Roofers. He showed up 90 minutes late with no call - and no apology. Took a 3 second look and declared it was the pipe. I told him I'd had another roofer and the fire department over (the leak caused all my alarms to go off) and they both thought it was from another location and what did he think. Suffice it to say he insulted me, implied everyone else was an idiot and refused to give me a quote (I'm the tenant, not the homeowner) and said he would speak only to the homeowner. I called the homeowner after (who are my good friends) and while his price is lower you apparently pay extra for warranty, aka he doesn't guarantee his work. The calls not mine since I don't own the place but I can certainly say I wouldn't recommend him...
