Estimating is where jobs are won and margins are lost. Rooftops AI builds the estimate directly from the measured roof — squares, pitch, complexity, and waste — then applies material and labor costs to produce a defensible range with a confidence score. No more guessing from the truck, and no more losing a week to the back office before the homeowner sees a number.

Roof replacement cost estimator
A planning range from roof size, material, and pitch. National 2026 ballparks.
Planning estimate from national installed ranges; local labor, tear-off layers, decking, and code items move real bids. A Rooftops AI report prices the exact roof with its measured size and complexity.
How it works
Measure automatically
Satellite measurement captures area, pitch, facets, and complexity — the inputs that actually drive cost.
AI prices the job
Material takeoffs and labor are computed for the measured roof, with waste factors matched to how cut-up it is.
Present a range you can defend
Deliver an estimate range with confidence scoring, then convert it into a branded proposal in one click.
What you get
Estimates from real measurements
The estimate inherits the measured squares, pitch multipliers, and waste factor — not a homeowner's guess about their own roof.
Materials and labor broken out
Tear-off, underlayment, shingles, ventilation, flashing, and labor appear as line items you can adjust before sending.
Ask the AI to sanity-check it
Roofy, the built-in roofing assistant, can walk through the estimating math — squares, pitch factors, waste — and flag anything that looks off.
Solar upsell built in
Every property includes solar potential analysis, so you can present a second option without a second tool.
What actually drives a roof replacement price
Five inputs set most of a residential replacement price: surface area, material, pitch, tear-off complexity, and locality. Area and material dominate. Architectural asphalt installs nationally in the mid hundreds per square; standing seam metal runs two to three times that; tile more. Pitch adds labor: past 7/12, crews slow down, harness up, and stage differently, which shows up as a steep charge. Second-layer tear-offs, bad decking, and code items (ice barrier, drip edge, ventilation upgrades) are the honest variance that separates a real bid from an internet average.
This is why a useful estimator starts from the actual roof rather than the house's square footage. Ground footprint understates a steep roof badly, and national averages carry a plus-or-minus that can swallow your margin. Measure first, then price.
Ballparks are for homeowners; bids are for measured roofs
The calculator above is a planning range, and that is exactly how to present ballparks to homeowners: a bracket that sets expectations before the real number. Where contractors get hurt is bidding from the bracket. A 40-square roof priced 8 percent under cost is a four-figure mistake, and the causes are almost always measurable up front: unmeasured pitch, unnoticed cut-up driving waste, or forgotten linear items.
A Rooftops AI report prices from the measured roof: its actual squares with a complexity-based waste factor, its ridge, valley, and eave footage for the linear items, and a labor profile that knows whether this is a walkable ranch or a cut-up two-story. The output is a defensible range you can hand a homeowner on the spot, with the measurements behind it when they ask why.
Presenting price without losing the job
Price objections are usually trust objections in disguise. The bid that wins at a higher number is the one the homeowner can see into: here is your roof's measured size, here is the material going on it, here is what the code requires, here is the range and why. Showing the satellite measurement does more for close rate than shaving three points of margin, because it converts your number from an opinion into a documented calculation.
The same documentation compounds on insurance work. When the carrier's estimate arrives short, your measured scope is the supplement's backbone: the missing drip edge has a measured footage, the waste factor has a stated basis, and the steep charge has a measured pitch behind it.

Frequently asked questions
How does the roofing cost estimator work?
It starts from satellite roof measurements — true facet area, pitch, and complexity — then applies material and labor pricing with an appropriate waste factor to produce an estimate range with a confidence score.
Can I adjust the numbers to my pricing?
Yes. The estimate is a starting point: line items can be edited before the proposal goes out, and the AI assistant can help you re-run the math with your own rates.
Is it accurate enough to quote from?
For most residential roofs, yes — and each estimate carries a confidence score so you know when to verify on site before committing to a number.
