To find your roof’s total square footage:
- Measure the length and width of each plane on the roof (including dormers), then multiply length times width.
- Add the square footage of each of the planes together.


Are satellite roofing estimates accurate?
Satellites are more accurate than the most experienced contractor’s hands. You’ll get EXACT measurements of your roof with no human error. We’ll even provide an estimate for costs based on the average roofing materials.
How do I measure my roof for metal roofing?
Determine the length of the metal panels needed for one side of your roof by measuring from the fascia board (the board attached to your roof joists) to the ridge (the peak) of the roof. For example, your roof could measure 12 feet to its peak. This number will tell you the total length of metal panels needed.

How much of my roof is flat?
From an insurance point of view, most companies consider a roof to be flat if it – or more than 25% of it – slopes less than 10 degrees. That’s why you’ll often be asked how much of your roof is flat when applying for a flat roof insurance policy.
How do you calculate rafter length?
If you are calculating rafter length from the center of the ridge beam, you will need to subtract half of the thickness of the ridge beam from the top end of the rafter. For example, if the ridge beam is 1.5 inches thick, subtract 3/4 of an inch from the overall rafter length.
