Materials, prices and the pitfalls of an estimate — with numbers and without advertising. If something can be calculated, we calculate it rather than speculate.
Shape, area, waste, accessories, installation and what the estimate leaves out. Every question has a price in tenge — we show it on a 180 m² roof.
Tiles that cost twice as much per metre make the roof only 1.6 times more expensive. And if you divide by the warranty term, the order changes.
Soft shingles are held by adhesive, which needs +5 °C or more. Composite tiles are nailed down. What the Almaty climate means and what to ask the contractor.
Metal is 6 dB louder than soft shingles, but what decides it is not the material but what is under the sheet. Which layers dampen the sound and what to ask before installation.
Weight, air under the sheet and rafters. When a new roof can go over old slate, when the slate has to come off, and what to do about asbestos.
The price difference is three to four times. We look at what you overpay for, when it is justified, and when metal tiles are the more honest choice.
Six shapes with top-view diagrams. And one house calculated three ways: the difference between a simple and a complex roof is about a quarter of the estimate.
An itemised estimate for a 120 m² house. What “turnkey” includes, which part can be calculated in a minute, and why contractors’ offers differ twofold.
Imported brands cost twice as much. We look at what you overpay for, and why local support matters more than the name on the box.
The area formula via the pitch, a ready table of multipliers, and why a four-slope roof costs 11% more than a gable roof of the same area.
