Know your numbers before you get quotes
Roofers price a replacement by the square — 100 square feet of roof. When three contractors quote your roof at 28, 33 and 37 squares, it is hard to know who is right. A Horus report gives you an independent measurement so you can compare quotes on equal terms.
What the numbers mean
- Total area and squares — the size of the roof surface, including overhangs.
- Pitch — how steep it is. Steeper roofs cost more to install.
- Waste — the extra material every roofer orders for cuts. 10–15% is typical.
