Siding estimating software: a wall-area takeoff from satellite imagery in seconds
How siding estimating software gets a wall-area takeoff without a site visit: perimeter from the building footprint, times storeys, less openings. Vinyl, engineered wood and fibre cement priced per square foot on your own website.
A siding takeoff needs one number: the square footage of exterior wall. Everything else — the vinyl, fibre cement or wood, the trim, the house wrap — is priced from it. Siding estimating software that works from satellite imagery gets that number in seconds, without a site visit, from two facts: the building footprint and how many storeys the house has.
The wall-area takeoff
The formula is short:
- Perimeter — from the building footprint traced on the satellite view.
- × storeys × 9 ft — the homeowner picks one, two or three storeys.
- − 15% — the usual share of wall taken up by windows and doors.
- + waste — the starter catalogue uses 10% for siding.
A 40 × 30 ft two-storey colonial: 140 ft perimeter × 2 × 9 = 2,520 sq ft gross, 2,142 sq ft net, about 2,356 sq ft with waste. That is the quantity your per-square-foot rate multiplies. Watch it happen on the siding demo.
What the footprint cannot see
Gable ends above the eave line, dormers, a walk-out basement, and a wraparound porch that is inside the footprint but has no siding. On a simple two-storey house the takeoff is typically within 10%; on a house with three gables it under-counts. Present the number as a range, confirm on site, and use the site visit to sell — the homeowner already knows the ballpark and asked for the visit.

Three starter tiers, each with a real product photo and an info card: vinyl, engineered wood and fibre cement, priced per square foot installed. Replace them with the lines you actually carry and your own rates; add house wrap, trim and old-siding removal as add-ons. Homeowner-facing cost ranges are in siding cost per square foot and quotes.
Siding estimating software compared
Takeoff tools built from drone or photo capture produce a detailed elevation-by-elevation measurement, and charge per report for it. That is the right tool for the final material order. It is the wrong tool for a website visitor who wants to know whether new siding is a $12,000 job or a $30,000 job before they talk to anyone. SatelliteQuotes is for that moment: instant range, lead captured, $49.99 a month flat. Details on the siding solution page and the alternatives comparison.
Common questions
How is wall area estimated from a satellite image?
Perimeter × storeys × 9 ft, less 15% for openings, plus waste.
How accurate is a satellite siding takeoff?
Within about 10% on a simple two-storey house; gables and dormers add area it cannot see.
Can I quote exterior painting the same way?
Yes, from the same wall area, per square foot per coat.
