What is the difference between click profiles and classic rolled roofing?

Click profiles are a modern alternative to rolled profiles – they can be installed quickly without special tools. The panels simply "click" together, forming a tight connection. Classic rolled profiles are connected mechanically and are more commonly used for more complex roof structures.

Is a metal roof suitable for the Latvian climate?

Yes, a metal roof is ideal for Latvia's changing climate – it can withstand rain, snow, frost and temperature fluctuations.

What is the warranty period for roofing?

Lebens metal roofs come with a warranty of up to 50 years, depending on the material used and the quality of the surface coating.

What are the advantages of a metal roof compared to other materials?
