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.

Full replacement, typical home$13,000 to $34,000Estimated installed range in Montclair for a single-family roof.
Per square, architectural asphalt shingle$650 – $950One square is 100 square feet of roof surface.
Emergency tarp-over$400 – $1,300Stops the water tonight. It is not a repair.

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

What a roof looks like as a monthly payment

Straight amortisation on the amount and rate you type in. Nobody is offering you these terms, us least of all — this is the arithmetic so you can check whatever a lender or a contractor does offer.

Prefilled with the middle of the typical Montclair replacement range. Change it to whatever you have been quoted.

Roofing paper commonly lands somewhere between about 7% and 18% depending on credit and on the programme. Put in the number you have actually been given.

The assumptions, in full

  • A fixed rate, equal payments, and interest compounded monthly. Nothing is deferred and nothing balloons at the end.
  • No down payment, no dealer or origination fee, no prepayment penalty, and no insurance product added on. Real roofing finance often carries a dealer fee, and it is usually already inside the price you were quoted.
  • Promotional "same as cash" and zero-interest offers work differently: the interest is typically owed retroactively if the balance is not clear by the deadline. This table does not model that.
  • The prefilled amount is the middle of the typical replacement range for Montclair from public cost data. It is not a quote for your roof.

Installed cost ranges, Montclair, CA. One square = 100 square feet.
CoveringPer squareTypical whole roofExpected life
Architectural asphalt shingleThe default choice on most American homes, and usually the right one.$650 – $950$13,000 – $27,50025 to 30 years
3-tab asphalt shingleThe cheapest thing that still counts as a roof. Fewer and fewer crews will install it.$525 – $725$10,500 – $21,00015 to 20 years
Impact-rated asphalt shingleClass 4 rated. Often earns an insurance discount where hail is a factor.$825 – $1,300$16,500 – $37,50025 to 35 years
Concrete tileThe tile lasts far longer than the underlayment beneath it, which is the catch.$1,200 – $2,000$24,000 – $58,00040 to 60 years
Clay barrel tileOften salvaged and re-laid over new underlayment rather than replaced.$1,600 – $3,300$32,000 – $95,50050 to 80 years

What moves the number

  • Warranty tier, which is really a question about who honours it in fifteen years
  • Pitch — anything over about 7:12 needs staging and slows a crew down
  • Permit and inspection fees, which vary more between towns than people expect
  • Ventilation work, if the old roof was cooking itself from underneath
  • Access — a truck that cannot get near the house adds hours to every load

Common repairs

Emergency tarp-over$400 – $1,300
Small leak, flashing or a few shingles$500 – $1,300
Valley, chimney or skylight reflash$950 – $3,000
Section replacement, one slope$1,500 – $5,200

Where these numbers come from. National installed ranges, adjusted for California labour and material costs and for how Montclair is actually built. They are a sanity check on the quotes you receive, nothing more. No contractor is bound by them.

Extras that turn up on quotes

ItemTypical rangeNotes
Roof inspectionFree – $493Frequently free when it is tied to an estimate. Paid inspections buy you a written report you can hold somebody to.
Tear-off, per layer per square$151 – $282Two old layers costs roughly twice what one does to remove and tip.
Seamless aluminium gutter, per foot$12 – $27Most homes run 160 to 220 feet.
Ridge and intake ventilation upgrade$626 – $2,549The cheapest thing you can do to make the next roof last its full life.
Tile lift-and-relay, per square$661 – $1,261Existing tile comes off, new underlayment goes down, the same tile goes back.
Skylight replacement, each$1,188 – $3,677Cheaper done during a re-roof than on its own afterwards.

Cost questions

Are you a roofing company?

No, and it matters that we say so. We are a referral service, not a contractor. The roofing work, the licence, the insurance and the warranty all sit with the independent company you choose.

Should I repair or replace?

It depends almost entirely on how much life is left in the material. Ask any contractor who inspects it to give you a number of years and a reason. If two of them independently say the same thing, believe it.

Is this really free?

It is free to you. Contractors pay to receive homeowner requests in their area. That is the entire business model, and we would rather say so plainly than pretend otherwise.

What should I do to prepare?

Clear the driveway, protect attic storage from falling dust, and plan for two loud days. Agree in advance where the dumpster goes and who sweeps for nails.

How long does a re-roof take?

A straightforward asphalt roof on an average house is one to three days. Tile, slate and complex rooflines take longer, and weather stops work more often than anything else.
