How your estimate is calculated
Four steps, every coefficient is open. You can repeat the same calculation on paper and get the same result.
1. Roof area
Enter it directly or via the house dimensions: the footprint is multiplied by 1.5 — a correction for pitch and overhangs.
2. Cutting waste
Gable — 7%, hip — 10%, complex — 13%. The coefficients come from a KAZROOF engineer, not padded “just in case”.
3. Accessories
Ridges, eave and verge flashings, fasteners: 18% / 28% / 38% of the tile cost depending on the roof shape.
4. Installation, optional
The rate depends on the shape: from 5,500 ₸/m² for a gable roof to 8,000 ₸/m² for a complex one. You can switch it off and count materials only.
What you get within 24 hours
- a materials estimate with a line-by-line comparison

- an engineer’s comment on your roof shape
The calculator gives an estimate: the engineer confirms the exact bill of materials from your drawing. We say this upfront so the total is no surprise.
