West Covina prices

Pricing a low-slope roof

Most flat sections on a house are small, which means the fixed costs of getting a crew there matter more than the area does.

What best describes your home?

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

No cost to you. Contractors pay us, you do not.

These are estimated ranges, not quotes. Compiled from public installed-cost data for California and adjusted for how West Covina is built. No contractor is bound by them, and nobody can price a roof they have not stood on.

What moves the price

  • How many old layers have to come off before the new one goes on
  • Permit and inspection fees, which vary more between towns than people expect
  • Pitch — anything over about 7:12 needs staging and slows a crew down
  • How much decking turns out to be soft once the covering is stripped
  • Whether the valleys, drip edge and step flashing are being replaced or reused

Locally

These winds are not constant, which is the problem. A roof gets nine quiet months and then one night at fifty miles an hour, and whatever was marginal goes.

Ask where the water goes and what happens when the drain blocks. On a flat roof that is not a detail, it is the design.

These are estimates, not quotes. They are compiled from national installed ranges adjusted for California costs and for how West Covina is built. No contractor is bound by them.

Questions about price

Do you handle commercial buildings?

We do. It is a different set of contractors — commercial and low-slope work is a separate trade from residential re-roofing — so answering the property question accurately matters.

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.

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.
