Google's Solar API uses high-resolution aerial and satellite imagery to measure roof area within ±5–8% of manual measurements. Combined with localized pricing data, estimates give a reliable cost range — not a binding quote, but close enough to plan your budget. ### What does the estimate include? Materials, labor, permit fees, and waste factor based on your roof's complexity. Accounts for roof pitch, number of facets (sections), and total area. Tearoff of existing material is included in the pricing range. ### Why do I see a range instead of one number? Roofing costs vary based on the contractor, material grade within a category, time of year, and local demand. The low end reflects competitive pricing; the high end accounts for premium materials and peak-season labor. ### Is my information shared with contractors? Only if you opt in. Getting an estimate is completely free and anonymous — no signup required. ### Does this work for any US address? Google's Solar API covers approximately 95% of US buildings. If satellite data isn't available for your address (common in very rural areas or new construction), you'll know immediately. ### How is this different from getting quotes from contractors? Traditional quotes require scheduling 2–3 in-person visits, waiting days for each estimate, and dealing with high-pressure sales.
