Select your current roof type and slope. Contractors price different materials differently — that is why we need to know what you have now.
Enter address — get the area
The system retrieves your building footprint from the map and automatically calculates the estimated roof area.
Compare and book a site visit
You'll see price estimates from local contractors (price per m² × area). Choose one and book a free site visit — the contractor will contact you to arrange a time.
