How to measure a property

1 · Find the property
Search the address, then zoom until the roof fills a good part of the screen.
2 · Identify the subject
Finds the mapped building at the address you searched, outlines it in amber and marks it SUBJECT. Everything else you measure stays a normal colour, so the bid sheet and site map always show which property they are about. Wrong building? Press the ★ on any area in the list to move the subject to it.
3 · Wand W
Click a clean, evenly-lit part of a roof or lawn — it grows to the edges of that colour and squares up the corners. Treat it as a first guess and correct it; shadow, trees and same-coloured pavement all throw it off.
4 · Fix it up
Click a shape to select, then drag the white corner handles. Click a hollow handle to add a corner, right-click one to remove it.
5 · Set the pitch
Aerials only ever show the flat footprint. Pick the pitch on each roof and the surface area and squares update.
If the address won't come up
Address data is incomplete in places, and the lookup service is occasionally unreachable. Pan to the street and use the Pin tool to click the property — it sets the subject directly and never touches the address lookup.

Auto Area Size

Which property are you measuring?

Enter an address or place name and the aerial opens right there. You can also paste coordinates like 35.2936, -120.6711.

Address not coming up? Skip, pan to the street, then use the Pin tool to click the property itself — that never needs the address lookup.

Reading roof pitch from a photo

Aerial imagery only ever shows the flat footprint — the rise is invisible from straight above, so pitch has to come from a side view. Open Street View on the roof and click the card that matches — that sets the pitch. The multiplier is what turns footprint into actual surface area.

Quick checks. A roofer can walk anything up to about 6/12, so "they walked it" puts you at 6/12 or below. Sight along the gable end and compare the slope to a 45° line: noticeably shallower is 4-6/12, right at it is 12/12. When you truly cannot tell, 4/12 is the most common residential pitch and costs you about 3% if you are one step off — but confirm before ordering.

Your price book

Your rates, stored in this browser and saved inside project files. Leave a line blank if you do not want it costed — blank means not priced and is reported as such on the bid sheet, never counted as zero. Roofing rates are per square (100 sq ft of roof surface), with material and labour separate because tile and metal cost more to lay, not just more to buy.
