Is metal worth the premium here?

Metal costs roughly double asphalt and lasts roughly three times as long. Whether that is a good trade depends entirely on how long you intend to stay.

Step 1 of 6

What best describes your home?

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

Free either way, and never more than three contractors.

What moves the price

  • How many old layers have to come off before the new one goes on
  • Access — a truck that cannot get near the house adds hours to every load
  • Where you land in the season; crews discount when the phone is quiet
  • Permit and inspection fees, which vary more between towns than people expect
  • Warranty tier, which is really a question about who honours it in fifteen years

Locally

Salt carries further inland than people assume. It shows up first as rust tracks on the vents and staining below the valley metal.

Ask any contractor quoting metal to show you a standing-seam job they finished several years ago. The edges will tell you what you need to know.

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

Questions about price

I rent. Can I use this?

Only the owner can approve roofing work. If you are renting, the fastest route is to send this to your landlord or property manager rather than gathering quotes nobody can act on.

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.

Should I repair or replace?

Rough rule: if the covering has more than about five years left and the damage is confined to one area, repair. If it is at the end of its life or you are patching the third leak in two years, you are paying instalments on a replacement.

What is it going to cost?

No cost, no obligation, and never more than three contractors.
