From my humble opinion, the roofer should really supply you with all of the pertinant information that you would need to make an educated decision without you even asking for it. If they don't have something that they can show you and give to you, how reputable are they.

Minimum 5 years in business

An actual office, not working out of their truck or home.

Fully insured.

Dump trailers not Dumpsters to protect your home and driveway.

How many roofs did they install last year and the year previous? 100+

Length of shingle warranty and labor warranty from their company. Minimum 25 years and 5 years on labor.

How long will job take and how long will my home be unprotected. For Asphalt shingles, Unless you have a really large home the job should be able to be torn off and re-roofed in 1 or 2 days. Most homes 1 day. Your home should not be unprotected EVER over night.

I hope this helps. Good luck with your project.

Below are a couple of possibly pertinent prior questions with answers on the skylight issue -

and one on questions to ask -

In addition to what other comment listed - don't forget the type of watershield (called underlayment by some but be careful because some people call the roof sheathing (plywood//OSB/particle board) the underlayment. Also, discuss:

1) if ALL flashing is being replaced (around story changes or dormers, upright walls or curbs, chimneys etc as well as valleys,

2) drip edging and its tie-in with the gutters so the water properly drips INTO rather than behind the gutters,

3) ice and water shield around chimneys and cupolas and higher story walls and along the lower edge of the roof,

4) whether roof jacks (penetrating pipe seals) and fan vents are being replaced, etc.

5) Also - provisions and pricing in the contract in case some of the sheathing needs replacement due to decay - best to have that contingency in the contract if needed, so you are not torn off and THEN arguing about pricing.

6) if they are working around the gutters or removing and replacing them or require that YOU have that done separately

7) cleanup, including stray debris pickup and running a nail sweep around to pick up scrap nails/staples, and whether they are hosing down and sweeping to pcik up the granules from the roofing from walks, decks, drives, etc.

8) on the overnight protection - as other comment said you have no guarantees on weather or that the contractor will actually be back on a multi-day job, so should be tarped. Your call on whether just having the water barrier down is enough - exposure to weather for a few days does not harm it, though high wind can cause it to tear, and tarpaper (roofing felt) should not be left exposed to rain or snow because it will wrinkle and bulge, which can make for uneven roofing under shingles or shakes or single-layer membrane or such products. Not a major issue under tile or sheet metal roofing or built-up roofing as long as not torn or badly wrinkled.

You can find other previous questions with responses in the Home > Roofing link in Browse Projects, if you wish to read up on roofing issues, some thoughts on roof life and brands, etc.
