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.

What moves the price

  • The number of penetrations: chimneys, skylights, vents, solar mounts
  • 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
  • Access — a truck that cannot get near the house adds hours to every load
  • How much decking turns out to be soft once the covering is stripped

Locally

They also drive ember risk, which is why vent screening and Class A assemblies matter more here than the colour of the covering.

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 Corona is built. No contractor is bound by them.

Questions about price

Is this really free?

Yes. You pay nothing, now or later. Roofing contractors pay us for the introduction, which is why the service costs you nothing and why we are upfront that it is how we make money.

How long should a roof last here?

An architectural asphalt roof is rated for twenty-five to thirty years and, in this climate, tends to land at the lower end of that. Tile and metal go much further, provided what is underneath them is maintained.

How much deposit is normal?

A third at most, and never the full amount. Pay the balance when the job is finished and you have walked it. Some states cap the deposit by law.
