Longer service life

Bitumen is more susceptible to ageing. Exposure to UV radiation and temperature fluctuations causes the material to harden and become brittle over time. After approximately 20 years, problems such as loose seams, hairline cracks, moss and algae growth, drying out, loss of mineral granules and leaks can occur, making renovation or complete replacement necessary.

Why EPDM offers better long-term value

EPDM may have a slightly higher purchase price per m² than bitumen, but the difference is much smaller than many people think. This is due to its high-quality composition, UV and ozone resistance and exceptionally long service life. When you look at the total cost over the lifetime of the roof, EPDM is always the more economical solution.

A bitumen roof generally needs replacing after 20 to 25 years, while an EPDM roof will still perform for many years afterwards. This means lower long-term costs for materials, labour and maintenance.

Simple and safe installation

Another major difference lies in the installation method. Bitumen must be applied using an open flame torch. This is time-consuming, requires experience and is not permitted on every roof. It also involves fire risks, particularly on timber substrates and renovation projects.

Where bitumen requires craftsmanship and experience, EPDM has been developed for reliable, repeatable installation, making it ideal for serial production and prefabricated construction. EPDM is cold bonded or available in self-adhesive versions. This means:

  • no risk of fire damage (helping to avoid additional insurance costs)

  • fewer tools required

  • faster installation

Because EPDM is available in large, seamless sheets, there are far fewer overlap joints and vulnerable areas. This also makes it easier to use around dormers, roof lights, upstands and roof penetrations.

In practice, EPDM roofs can be installed up to 30–40% faster than bitumen roofs, mainly because torching, multiple layers and cooling times are eliminated.

A more sustainable and future-proof solution

Bitumen is a petroleum-based product that hardens over time and eventually has to be disposed of. EPDM is fully recyclable, remains flexible throughout its lifetime and contributes to energy-efficient and airtight buildings.

Our high-quality EPDM is Cradle to Cradle Certified® and helps contribute to meeting energy performance requirements for nearly zero-energy buildings.

For companies looking to build more sustainably or work in line with modern building regulations, EPDM is the logical choice.

Moisture and airtight construction

Combined with Pandser foils, tapes and accessories, EPDM forms one complete system for the entire building envelope.
