Find your house on real aerial imagery and trace it - roof area for restorations and repairs, or gutter length for replacement and gutter guard. Pick your profile, tell us the storeys, and send it straight into a quote. No ladder required.
Tap a length to type the exact number · drag dots to move · dots between corners add a corner · right-click deletes · ⌘Z undoes · marks downpipes.

How it works
Measure once, from the couch.
It auto-traces your building outline from OpenStreetMap footprint data over real aerial imagery. Every edge shows its length live; drag any corner to match your actual roofline, tap a length to type the exact number, and add extra sections for the garage, patio or shed.
In gutter mode, tap the sides that have no gutter and they drop out of the total - because almost no house has gutter on every wall. Mark your downpipes, pick your gutter profile and storeys, and the whole spec - section by section - lands in your booking so we arrive already knowing the job.
It's free, with no sign-up. Roofers, painters and solar installers are welcome to use it too.
