No, modern Eternit is 100% asbestos-free and safe.
Advantages over metal?
It’s silent during rain, non-corrosive, and prevents condensation.

Lifespan?
50+ years. The material typically comes with a 30-year warranty.
Fire safety?

How to calculate usage?
Total roof area + overlap + cutting waste (15–20%).

Ridge length, eaves, rafter length, and the pitch angle.
Can I walk on it?
