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.

Before you let anybody on the roof

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

  • Which underlayment, and whether ice-and-water goes on the eaves and valleys
  • Tear-off or overlay, and what the local code allows
  • Ventilation: what is there now, what it should be
  • A written per-sheet price for replacing bad decking
  • How the site is protected, and who cleans up the nails

Warranties come in two halves that get deliberately confused. The manufacturer covers the material, and only if it was installed to specification. The contractor covers the workmanship, and only for as long as they stay in business.

Two quotes at the same price can be very different roofs. Compare the layers, not the brand name on the shingle.

Insist on knowing what happens to decking that turns out to be rotten. The good answer is a per-sheet price agreed in writing before the job starts.

Locally

Behind it: wind-blown embers landing in the valleys. Class A assemblies and closed-off vents matter more here than the colour of the shingle.

About replacement here

Do you cover the whole Los Angeles County area?

We match across West Covina and the neighbouring communities in Los Angeles County. Put the ZIP of the property in and it will route to whoever actually covers it.

Why three quotes and not one?

Because one price tells you nothing. Three tells you where the middle is, and the outliers are informative in both directions — the very cheapest is usually leaving something out, and the most expensive should be able to say what you are getting for it.

What does a new roof cost in West Covina?

Most quotes here for a standard asphalt replacement come in around $12,500 to $31,000. That assumes one layer to remove and sound decking. Every quote you get should say in writing what happens if the decking is not sound.

Do I have to hire anyone?

No. Take the quotes, sit on them, use them to argue with your insurer, or throw them away. There is nothing to cancel and nothing owed.
