How we measure
Your roof is measured from aerial imagery of your address — every facet, pitch and edge — then confirmed on site before you sign. That’s how you get an honest planning range in about 90 seconds, instead of waiting on a sales visit for a guess.
The method
Every step keeps its source and status visible, so the number you see is traceable back to your actual roof — not a rule of thumb or a round guess.
From your address we pull recent aerial and orthophoto imagery and isolate your roof — the main house plus the garage. Attached homes (townhouse, semi) are handled per unit, because imagery can’t see the party walls.
Every facet, ridge, hip, valley and edge is outlined, so the roof area reflects the real, three-dimensional surface — not the flat footprint you’d get from a map or a tape across the driveway.
Slope, facet count and access are what actually move the number. A steep, cut-up roof has far more surface and labour than a simple bungalow of the same footprint — which is why two homes on the same street can price differently.
The measured quantities are multiplied by deterministic, published per-square rates — the same math every time. That produces an honest planning range from your address, with no salesperson deciding your number on the spot.
Why it’s a range
A measurement from the sky is powerful, but it has limits — and pretending it doesn’t is how homeowners get surprise change orders. Here’s exactly what the roof read can and can’t tell us.
Accuracy, honestly
The planning range is measured from your roof, not guessed — but it stays a range until the roof is checked.
We never claim survey-grade precision from imagery alone; the read shows its source, date and confidence.
Townhouses and semis are measured per unit — aerial can’t see the shared walls, so we split conservatively rather than over-promise.
Concealed conditions like rotted decking or an extra layer are priced per unit and only charged when found, with a photo you approve.
Questions
For roof size, shape, slope and facet count, aerial measurement from recent imagery is accurate enough to build an honest planning range — it reads the real three-dimensional surface, not just the footprint. What imagery can’t see is what’s underneath: layers, decking condition and access. That’s why the aerial read gives you a range, and a firm price is confirmed with photos or an on-site look before you sign.
We measure the roof from aerial imagery of your address, then multiply the measured quantities by published per-square rates. The math is deterministic, so the same roof always produces the same range. A visit or photo check is still needed before a firm, signed price — but you don’t need one to get a realistic planning range.
Because two things stay unknown until the roof is checked: how many shingle layers have to come off, and the condition of the decking underneath. Both change the price. An honest range plans for that; a fake “exact” quote from a photo either pads the number or hides a change order for later.
Yes. Aerial imagery can’t see the party walls between attached units, so we measure your unit’s roof area per unit and split shared runs conservatively. You get an honest estimate for your section rather than a whole-block number divided by guesswork.
Yes. You get the measured roof read and planning range from your address first. Contact details are only needed if you want a person to review the roof, save the file, book a look, or issue a firm proposal.
Type your address and watch the roof get read — size, pitch and complexity — then get an honest planning range. No sales call, no one at your door.
