I had used an old established company who readily extended a warranty
of 30 years. My neighbors weren't so lucky since the roofing company they had chosen, seemed to be a fly by night operation, and two years down the road, their roof was leaking badly and the roofer was out of business.
Really look at that warranty. The materials are guaranteed by the manufacturer (usually 20, 25 or 30 years), but you want a workmanship warranty -- one that covers the quality of the installation, separate from the material.
I'd also ask to see their insurance. (In fact, I asked for a copy of their insurance!) If anyone or anything gets hurt during the construction, their insurance should cover it, not yours. And if your area requires roofers to have a licence, ask to see that as well. There's a lot of fly-by-nighters in the roofing biz, with no insurance, no licence and slipshod methods.
I'm a little ambivalent on asking for references -- it's too easy for them to give a friend's name who will, of course, give a glowing reference.
I agree completely that the cheapest isn't necessarily the best. Follow standard bid acceptance practices -- get 4 or 5 quotes, discard the lowest and the highest, look carefully at the ones in between. And make sure you're comparing apples to apples, i.e. each quote is for exactly the same products and amounts. If you want to add anything after the selection, adjustments can be made before signing the contract.
As for dust -- yeah, I got some. Probably due to my lax housekeeping -- the vibrations knocked it all down from the ceiling.
My roof took several days, only because it rained unexpectedly. But having a dumpster on my driveway was very handy! (I was cleaning out the basement at the time and some old drywall bits and studs ends magically found their way into it.)
It's amazing how fast these guys can work.
