Roof cost calculator

People search this phrase wanting a dollar number. The honest version is: you bring $/square (materials, or a local ballpark), we multiply by squares from area × waste. We do not scrape market prices, book crews, or write insurance estimates. Use the roofing calculator for squares first, then plug a $/sq you trust — store materials receipt, neighbor’s invoice, or a published regional ballpark you accept as fuzzy.

How it calculates
materials ≈ squares × materials $/sq; optional total ≈ squares × all-in $/sq + fixed fee. Rates are yours — we do not scrape prices.

Estimate only — not a bid. Not a contractor quote or insurance estimate. You enter $/square.

When to use

Sanity-checking whether a verbal “about $X per square” lands near your square count; materials-only budget before you call anyone.

When not to

Filing an insurance claim. Choosing a contractor from this page (there is no directory). Metal vs tile lifecycle cost studies. Anything that needs a site visit.

Assumptions

Cost ≈ squares × $/square (+ optional flat fee you enter). Defaults are placeholders — replace them. No automatic city price index. Labor vs materials split only if you enter two rates. Strong disclaimer on page and ticket.

Worked examples

Example 1

15 squares, materials $120/sq
→ ≈ $1,800 materials

Your shingle SKU may be $90 or $200 — the field is yours.

Example 2

15 squares, all-in ballpark $450/sq
→ ≈ $6,750 fuzzy total

Steepness, stories, tear-off, and region swing this wildly — treat as conversation starter, not a bid.

How it calculates

Squares × your $/sq rates — nothing scraped.

  1. Enter squares (from the roofing calculator).
  2. Enter materials $/sq and/or all-in $/sq you trust.
  3. Optional fixed fee; read materials and total ballpark.
squares from surface/waste (or entered)
materials ≈ squares × materials_$/sq
optional total ≈ squares × all-in_$/sq + fixed costs

Common traps

  1. Placeholder $/sq lies if you leave it untouched.
  2. Tear-off, plywood, permits, dumpsters often sit outside neat $/sq ads.
  3. We will not collect your phone for “free local quotes.”
  4. Insurance ACV/RCV is a different universe.

FAQ

Roughly squares × local $/square — you must supply the rate; we do not invent your city’s price.
