Step 1 of 6

What best describes your home?

Different buildings need different crews, so this is the first thing a roofer asks.

Free. You are not committing to anything.

Be careful with the deposit

Never pay in full up front, and never in cash without a receipt that names the company. Progress payments tied to milestones protect both sides.

Get everything in writing, including the unknowns

Anything agreed verbally will be remembered differently on day two. In particular, pin down the decking rate, the start date and the clean-up before you sign.

Prefer somebody you could drive to

Ask where their yard is. Companies that follow storms across state lines do competent work and then vanish, which is fine right up until something needs putting right.

Compare scope, not totals

Lay the quotes side by side line by line. Underlayment type, ice-and-water coverage, drip edge, valley treatment, ventilation, flashing replacement, decking allowance and warranty. Large gaps in the total are almost always gaps in the scope.

Ask for current certificates of insurance

You want general liability and workers compensation, both current, and ideally sent directly from the insurer rather than as a photocopy. If an uninsured worker is hurt on your roof, the exposure can land on your homeowner policy.

Check the licence yourself

A licence number on a business card is not a licence. Look it up, confirm the name on the licence matches the name on the contract, and check the status is active today.

In short

Three quotes, three licence checks, three certificates of insurance. It is a dull hour that routinely saves five figures.

Related questions

Are gutters included in a re-roof?

Usually not, unless the quote says so. If they are near the end of their life, replacing them during the re-roof is meaningfully cheaper than doing it later, because the crew and the staging are already there.

It is leaking right now. What do I do?

Move what you can out of the way, put a bucket under it, and if there is a bulge in the ceiling put a small hole at its lowest point to let the water out in one place rather than bringing the whole panel down. Then mark your request as an emergency — those go out first.

Why does ventilation keep coming up?

Because a badly ventilated attic cooks the roof from underneath and takes years off it. Intake at the eaves and exhaust at the ridge, in balance. It is cheap during a re-roof and awkward afterwards.
