Replacing your roof: what it really costs

What drives the price, typical installed costs by material, and how to compare bids on equal terms.

What actually drives the price

A roof quote is mostly three things: the size of the roof, how steep and complicated it is, and the material you pick. Two houses on the same street can be thousands apart because one has a simple gable and the other has valleys, dormers, and skylights that all need flashing.

The number you should compare bids against is price per square — roofers measure in “squares” of 100 square feet. If one bid works out to a wildly different per-square price than the others, that is your signal to ask why: better shingles, or missing work?

Rough cost by material

Planning ranges for a typical single-family home, fully installed (tear-off included). Your real number depends on size, pitch, and region.

Roof material Typical installed range
Asphalt shingles (3-tab) $6,000 – $12,000
Architectural / dimensional shingles $9,000 – $18,000
Standing-seam metal $15,000 – $40,000
Tile (concrete or clay) $12,000 – $45,000
Cedar shake $18,000 – $35,000

These are planning estimates, not quotes. Steep roofs, multiple layers to tear off, and hard-to-reach homes push costs toward the high end.

Three ways to pay less without cutting corners

Ask about a roof-over (sometimes)

If you have only one existing layer and the deck is sound, installing over the old shingles can save on tear-off. It is not always allowed or wise — but it is worth asking about.

Check insurance and storm discounts

If a storm damaged your roof, part of the cost may be a covered claim. Impact-resistant shingles can also earn a standing discount on your premium in many states.

Time it, and get three real bids

Roofers are cheaper and more available in the off-season. Always get three itemized bids — not to grind the price, but to see what a fair scope actually includes.

Red flags in a roofing quote

Most roofers are honest. Slow down if you see any of these:

  • A single lump-sum price with no breakdown of tear-off, materials, flashing, and disposal.
  • No mention of what happens if they find rotten decking underneath (this is the classic surprise upcharge).
  • Pressure to sign today, a “storm chaser” who knocked on your door after bad weather, or an offer to “cover your deductible” (that one is insurance fraud).
  • A deposit well outside the normal 10–30% range before any materials arrive — and never pay in full up front.
  • No written workmanship warranty, or a company with no local track record.

Not sure whether to repair or replace?

If the roof is under ~15 years old and the damage is localized, a repair may buy you years. Run the comparison first.

Common questions

How long should a new roof last?

Architectural asphalt shingles typically last 20–30 years; metal roofs typically last 40–70 years, and tile can last 50 years or more. Lifespan depends heavily on ventilation, installation quality, and climate.

Will insurance pay for a new roof?

Insurance covers sudden damage from a covered event like a storm or fallen tree — not wear-and-tear or age. One important catch: on older roofs, some policies pay only the depreciated value (ACV) rather than full replacement cost — check which kind you have. If a storm is involved, document it and ask your insurer before you sign anything.

Is the cheapest bid a bad idea?

Not automatically — but understand why it is cheaper. A low bid often excludes tear-off, new flashing, permits, or decking repair. Compare what is included, line by line, not just the total.

Do I need to be home during the work?

Usually not, but it helps to be reachable. The one moment that matters is if they open the roof and find rotten decking — you want to approve that change order, not discover it on the invoice.
