Comparing roofing materials by price per square meter is like comparing cars by purchase price and ignoring fuel, maintenance, and resale. The number that matters is total cost of ownership over the building's service life.

The Components of Total Roofing Cost

A complete cost comparison includes: material cost (tiles + accessories + fasteners), structural cost (heavier roofing needs stronger structure), installation cost, freight cost, maintenance cost over the service life, and replacement or major repair cost. When you add these up, "cheap" materials often become expensive, and "premium" materials often deliver lower total cost.

Material-by-Material Breakdown

Where the Hidden Costs Hide

Metal: the big hidden cost is maintenance. Repainting a large metal roof costs more than the original material. Ceramic: the hidden cost is in the structure — 4–6* heavier than resin tiles, driving up truss and foundation cost. Synthetic resin: the cost to watch is specification downgrading — insufficient UV protection means the tile ages faster.

How to Present This to Your Customers

Distributors who sell on total cost rather than price per square meter win larger projects. Prepare a simple comparison sheet: material + structure + installation + 10-year maintenance estimate. When your customer sees the "cheaper" metal roof costs more after the first repaint cycle, the decision becomes clearer.
