What Is Satellite Roof Estimate?
The estimator takes a street address and returns five things: a range of roofing squares, a range of dollars across that same range, the roof’s predominant pitch, the date of the satellite imagery it read, and the city, state, and ZIP code it matched. One square is 100 square feet, the unit the rest of a roofing estimate is written in. The dollar range is the square range multiplied by a single retail rate per square, and that rate is returned alongside the range, so the arithmetic is visible rather than asserted: the same roof read twice prices the same way twice. The width of the range is a stated band, not an accuracy claim. In the estimator’s own words: “An estimate from satellite imagery; not a measurement. The range is a stated band around the satellite figure, not a measured error. The exact figure requires an on-site measurement.” No accuracy figure is published, because none has been measured: the disagreement between what imagery reports and what a tape measure finds on a real roof is an open question here, and a band that was chosen is described as chosen. Four checks run before any number is returned, and each of them can stop it. The address must resolve to a rooftop or an interpolated street position. The building the imagery returns must sit within a bounded distance of that address and in the same ZIP code. A canopy check compares the city’s own building footprint against the imagery’s roof mask, to answer whether the picture showed the whole roof or only the part the tree cover left visible. And where lot records are available, a parcel check asks whether that building falls inside this address’s lot. When a check does not pass, the estimator declines and names which one: trees cover too much of this roof for a satellite estimate; there is not a clear enough satellite picture of this roof; which roof on the lot is yours could not be confirmed; this roof could not be checked against the city’s property records; that address could not be placed on a roof. Every one of those answers ends the same way — call, and we will measure it on site. The refusal is a designed output rather than a failure. A number produced from a picture that did not show the roof is worse than no number at all, because it looks like an answer. What a satellite estimate is not is a quote. Pitch, the number of layers to be removed, the condition of the decking underneath them, and the flashing details at every interruption all move a real price, and none of them is legible from above. The written, itemized estimate — the document the work is actually bought from — comes after someone has been on the roof. The satellite range is where the conversation starts, not where it lands. The imagery and building data underneath the estimate come from Google, and the estimator carries Google’s required attribution for them: “Includes solar data from Google.”
Important Distinction
Note: A satellite estimate is neither a quote nor a measurement. The range it returns is a stated band around a figure read from imagery — not a measured error — and it prices at a published rate rather than at the cost of one specific roof. A written, itemized estimate follows an on-roof inspection. The two documents answer different questions and should not be compared as though they were the same number.
What Zilker Roofing Will Not Do Here
4 refusals returned instead of a number — each a hash-verified commitment you can check.
A roof that tree cover hides from satellite imagery is measured on site. When the canopy check finds that the imagery showed only the part of the roof the trees left visible, the satellite estimator returns no number for that address and asks the homeowner to call so the roof can be measured in person.

A roof the satellite imagery does not cover clearly is measured on site. When Google holds no building at that point at the quality the satellite estimator requires, the estimator returns no number for that address rather than a guess, and the same address will get the same answer until a person has been on the roof.

A roof that cannot be confirmed as the roof at the typed address is measured on site. The satellite estimator prices a building only when it sits within a bounded distance of that address, in the same ZIP code, and, where lot records exist, inside that address's lot; when any of those checks fails, it returns no number and asks the homeowner to call.

A roof length the satellite geometry cannot settle is held rather than estimated. The homeowner's satellite estimate shows a range of squares, a range of dollars across that range, the predominant pitch, the imagery date, and the city, state, and ZIP code; it shows no length, no facet, and no coordinate, and a figure the geometry holds is withheld rather than shown as zero.

The retail rate for a satellite roof estimate from Zilker Roofing is $425 per square, where a square is 100 square feet of roof, as of September 18, 2026. It is the one published rate the estimator multiplies its square range by; it is a rate, not the price of any particular roof, which is written only after an on-site measurement.

How Satellite Roof Estimate Relates to Other Topics
A satellite estimate is read from imagery and priced at a published rate; a written, itemized estimate prices one specific roof after someone has inspected it. The first orients a homeowner on scale; the second is the document the work is bought from.
Typical Austin project bands, and the factors that move a roof within them, are stated on the roof replacement cost page. The estimator does something narrower: it returns a range for one address, not a band for the market.
The estimator measures and prices in squares — one square is 100 square feet — which is the same unit the rest of a roofing estimate is written in, and the reason a range of squares can be compared against a written scope line by line.
Predominant pitch is one of the few things imagery does report, and it is also one of the larger drivers of what the work costs: above roughly 7/12 a crew needs harnesses and staging, and the labor per square moves with it.
A satellite range is where a roof conversation starts. The on-site inspection is what turns it into a number someone will put in writing and stand behind.
The dollar range the estimator returns is its square range multiplied by one published retail rate per square, stated on this page as a governed claim with its own hash rather than restated in prose.
