Below are a few arguments in favour of choosing a bitumen roof. Bitumen roofs, also known as felt roofs, have several benefits:

• durable – rubber bitumen roofs installed in the 1970s are still in use
• quiet – you cannot hear the rain indoors
• elastic – suitable for roofs with a complex form
• thanks to the rough surface, snow stays on the roof and does not fall on passers-by
• the appearance of the roofing lasts as the years pass: the surface does not rust, become loose or fade
• there are plenty of options – there is a technically and aesthetically suitable option available for any roof
• there are products available up to a pitch ratio of 1:20 that do-it-yourself builders can install on their own (easy to work with a blade hook utility knife)
• durable and compact: a solid wood underlay increases tightness and stabilises the structure of the whole house
• economic as a whole (whole structure + installation + maintenance).
