Why accurate roof measurements matter
When you’re comparing contractor quotes, you need to know what you’re paying for. If one contractor quotes 2,200 sq ft and another quotes 2,800 sq ft, who’s right? Your free roof report gives you the answer.
How homeowners use their roof report
Compare quotes fairly: Know if a contractor is overestimating your roof size
Budget accurately: Estimate costs before calling anyone
Insurance claims: Have documentation ready for adjusters
Negotiate confidently: Armed with real data, you’re in control
What you get with every report
- Total roof area: Combined square footage of all roof surfaces
- Section breakdown: Individual measurements for each roof facet
- Pitch data: Slope measurements that affect material costs
- Orientation: Compass direction for each section (useful for solar)
- Imagery date: Know how recent the satellite data is
What to check in contractor quotes
Your roof report shows your actual size. Any reputable contractor should be within 5% of that number. If a quote is way higher or lower, ask questions—it could be a red flag.
Is this a free roof estimate?
Yes — and you don’t have to wait for a contractor to visit. Enter your address above and you’ll get an instant, free roof estimate built from satellite data: your exact roof size plus a national cost range for a replacement. It’s the fastest way to get a free roof estimate online before you ever pick up the phone.
Free roof estimate by address — what you’ll see
Your roof size: total square footage and a section-by-section breakdown from satellite imagery
A cost range: a national price range for a new roof, so you can budget before any quotes
No sales calls: no waiting for an in-person estimate, no signup, no obligation
Use your free roof estimate to sanity-check contractor quotes: a fair roof quote should line up with your roof’s real size and the typical cost range for your area. If a quote comes in well above that, it’s worth asking why.
Frequently asked questions
How accurate are these measurements?
Satellite-based roof measurements are typically accurate within 2-5% for standard residential roofs. Complex roofs, trees, or recent construction may affect accuracy. We recommend on-site verification for final quotes.
What addresses are covered?
We have coverage for most residential and commercial properties in the United States. Rural or newly constructed properties may have limited or no data available.
How recent is the satellite imagery?
Imagery dates vary by location but are typically within the last 1-2 years. The report shows the exact imagery date so you know what you’re working with.
Can I use this to compare contractor quotes?
Absolutely! That’s one of the main reasons homeowners use this tool. When you know your actual roof size, you can spot if a contractor is overestimating (which means higher costs for you).
How does this tool get roof measurements?
We use satellite imagery and advanced mapping technology to calculate your roof’s size, pitch, and sections. It’s the same technology used by insurance companies and roofing professionals.
