Is your flat roof due for renovation?

A well-installed flat roof lasts an average of 25 to 50 years, depending on the system and maintenance. Some roofs I can help last years longer with a targeted repair. With major damage or aging, full replacement is ultimately cheaper than patching.

Unsure whether your roof needs renovation? Request a quote. We look at what is needed and you receive a clear, tailored quote. During a flat roof renovation you can directly include dakisolatie en een skylight.

Bitumen or EPDM: which suits your roof?

I give honest advice. Bitumen is proven and more cost-effective; EPDM lasts longer and requires less maintenance. Which choice works best depends mainly on the shape and use of the roof.

Bitumen

Proven classic

Two layers of modified bitumen, torch-applied or cold-bonded. The workhorse of flat roofs. Easily repairable and suitable for more complex shapes with many penetrations.

Guide price
€45–85/m²
Lifespan
25–30 jaar
  • Affordable to purchase
  • Easy to repair or patch locally
  • Works well around roof windows and penetrations
  • Decades of references in Northern Netherlands

Suitable for homes with complex roof shapes, dormers and extensions with many penetrations.

EPDM

Seamless rubber

Synthetic rubber membrane, often laid as a single sheet on the roof. No seams or bonded edges. Ideal for straight, larger roof surfaces that you want to leave alone for a long time.

Guide price
€90–140/m²
Lifespan
40–50 jaar
  • Very long lifespan, low maintenance
  • Seamless, fewer weak points
  • Resistant to UV, frost and temperature fluctuations
  • Excellent load-bearing for roof terrace or green roof

Suitable for homes, extensions, dormers, garages and commercial buildings.

Frequently asked questions

Question not listed? Feel free to contact us, I am happy to help.

A new bitumen roof costs an average of €45 to €85 per m² including labour and VAT. EPDM is typically between €90 and €140 per m². The total price depends on insulation, surface area, roof edges and accessibility. After a no-obligation roof visit, you receive a clear quote with no fine print.
Bitumen is proven, easily repairable and lasts 25 to 30 years. EPDM is a rubber membrane that lasts 40 to 50 years and is laid in a single piece. Ideal for larger, straight roof surfaces. For complex shapes and roof penetrations, bitumen often works better. I give honest advice on which system suits your roof.
An average flat roof of 30 to 60 m² is usually replaced in 1 to 3 working days, including insulation and new roof edges. Larger projects are planned in phases so your home or business remains accessible.
You receive a 10-year warranty on installation. In addition, the manufacturer warranty on the roofing material applies, often 10 to 20 years from reputable suppliers.
Yes, I actually recommend it. If the roof is being opened up anyway, insulating at the same time is by far the most cost-effective moment. With PIR insulation you immediately meet current Rc values and you often qualify for ISDE subsidy.
I schedule new projects typically within 4 to 8 weeks after approval of the quote. For urgent leaks or storm damage, we come the same day or the next working day for an emergency repair.
