How to Measure Gutters and Roofs from Satellite Images — Before You Roll a Truck
Every contractor knows the cost of a "quick measure trip." Fuel, an hour of windshield time, a ladder up and down — and half the time the job was never going to close. Satellite measuring flips that around: you trace the house from an aerial photo, get your gutter runs and roof lines, and price the job before anyone leaves the shop.
What a satellite takeoff gives you
Working from the aerial photo, you trace the edges of the roof and the tool turns your lines into measurements:
- Gutter runs — total eave footage, which becomes your gutter coil footage
- Downspouts — count and placement, with drops estimated from the runs
- Roof lines — ridges, hips, valleys, and rakes for roofing bids, with waste calculated in
- A clean diagram — the traced outline becomes the drawing on your bid sheet and roof report
The measuring isn't magic, and a good system shouldn't pretend it is. You place the corners; snapping and straightening tools help keep lines true, and the math — footage, pitch adjustments, waste — is done for you. The result goes straight into the bid: no re-typing numbers from a notebook into an estimate later.
Where satellite measuring fits (and where it doesn't)
Satellite takeoffs are strongest for:
- First quotes — get a real number to a homeowner the same day they call
- Screening — know whether a job is worth the drive before you make it
- Insurance and storm work — document the roof with a labeled report the adjuster can read
It doesn't replace eyes on a roof for final verification on complicated jobs — hidden damage, flashing condition, and rot still need a visit. The point is that the visit happens once, for a job you've already priced and likely already sold.
How it connects to the bid
In NCGS CRM, the satellite takeoff feeds the estimate directly: measured footage becomes the bid sheet, materials become a pick list for loading the truck, and the traced diagram prints on the customer-facing roof report under your own letterhead.

The bottom line
Measure twice, drive once. If your current process is "drive out, measure, drive back, type it up, then quote," a satellite takeoff cuts that to one screen and a few minutes — and your bid is in the customer's hands while your competitors are still scheduling the measure trip.
