Cost factors to check first

Roofing square

One roofing square equals 100 square feet of roof surface.

Material system

Asphalt, metal, tile, and membrane systems should not be compared with one blended per-square number.

Labor and access

Pitch, stories, safety setup, and staging can move labor cost per square.

Included scope

Per-square pricing may or may not include tear-off, disposal, underlayment, flashing, and permits.

Use the matching calculator

Use the unit conversion calculator to move between square-foot pricing, roofing squares, included scope, and total estimate.

Quote checklist

Convert roof square footage to roofing squares by dividing by 100.

Ask what each per-square quote includes before comparing totals.

Keep material and labor lines separate when possible.

Use the same tear-off and underlayment assumptions across all bids.

Roofing square conversion

A roofing square is a contractor unit equal to 100 square feet of roof surface. A 1,850 sq ft roof is 18.5 roofing squares before waste. This page is useful when one estimate is quoted per square foot and another is quoted per roofing square. Convert the unit first, then compare the included scope.

Input	Conversion	Result
1,800 sq ft roof	1,800 / 100	18 roofing squares
$7.50 per sq ft	$7.50 x 100	$750 per roofing square
$950 per square	$950 / 100	$9.50 per sq ft

Material-only, installed, and full-scope pricing

Per-square pricing is only meaningful when the scope is named. Material-only pricing may cover shingles, membrane, tile, or accessories without labor. Installed pricing normally includes labor for the new roof system. Full-scope pricing may also include tear-off, disposal, underlayment, flashing, permits, cleanup, and warranty requirements.

Scope	Usually includes	Do not compare against
Material only	Roof covering and sometimes accessories	Installed quotes with labor and disposal
Installed	Material plus installation labor	Full replacement bids that include tear-off and deck allowances
Full scope	Installation, tear-off, disposal, flashing, cleanup, and allowances	A simple material quote
