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.

Before you let anybody on the roof

The things worth pinning down on a repair job. A contractor who has not raised them has not looked properly.

  • Whether matching material is still available in your colour
  • Whether the surrounding material has enough life left to be worth tying into
  • What it would cost to replace instead, so you can compare like for like
  • Where the water is actually getting in, not just where it is showing up
  • What the repair does to any remaining manufacturer warranty

A good repair visit starts in the attic, not on the roof. Daylight through the deck, wet insulation, and rust tracks down a nail shank all say more than a walk on the shingles.

Leaks rarely start where the stain is. Water travels along the underside of the deck and down a rafter before it drops, which is why a repair that goes straight to the discoloured patch usually fails twice.

Ask directly: how much life is left in the covering? A contractor who will give you a straight number, and say why, is worth more than one who is cheapest.

Locally

The second problem is ember intrusion through vents and open eaves. Most houses lost to wildfire are lost to embers arriving ahead of the fire, not to the fire itself.

What happens to my information?

It goes to a maximum of three roofing contractors working in Montclair, and to nobody else. We do not sell it as a mailing list and we do not post it anywhere public. Our privacy policy sets out exactly what is shared.

What time of year is best to re-roof in Montclair?

Practically, the long dry run from May to October. Crews are busiest right after the weather turns — November through March — so booking outside that stretch usually buys you a better date and a keener number.

Can I stay in the house while it is done?

Yes, though it is loud, and things will fall off shelves in the garage. Move cars out of the driveway and take anything fragile off the walls of the top floor.

How many contractors will contact me?

No more than three. We picked that number because two quotes is not enough to spot an outlier and five is an ordeal.
