Need a flat roof installed or maintained?

Koning Dakwerk BV is happy to advise you about the options

A flat roof requires more attention than a sloped roof. Because of its horizontal position, water remains longer and dirt can accumulate more quickly. Regular roof maintenance prevents leaks, cracks, and premature wear. We recommend inspecting a flat roof at least twice a year, for example, in the spring and after fall. This prevents clogged drains and ensures a longer roof life.

Do you want to be sure about the condition of your flat roof? King Roofing BV is happy to perform a professional roof inspection. This will prevent unexpected costs and extend the lifespan of your roof.

Roofing for a flat roof

There are several types of flat roofing, each with its own advantages and disadvantages. But which roofing is best suited for a flat roof? When should you replace a flat roof? Proper maintenance significantly extends the lifespan of a flat roof.

King Roofing BV is happy to advise you on the options available, so that your investment immediately yields a higher return.

✅ Bitumen roofing for a flat roof

Bitumen remains the classic choice for flat roofs, thanks to its excellent waterproofing and relatively low cost. APP bitumen is UV-resistant and ideal without an additional protective layer. SBS bitumen requires a protective layer, like gravel, but offers greater elasticity and is less sensitive to temperature fluctuations.

✅ Flat roof maintenance

Good maintenance significantly extends the lifespan of a flat roof. 

✅ Replace flat roof

If we notice any blisters, cracks, loose seams, or leaks, it's time to replace the roof. If you're insulating your roof, this is also the perfect time to install new roofing.

✅ Roof insulation

While you're busy with maintenance or replacement, consider roof insulation. Good flat roof insulation significantly reduces your energy bill and increases living comfort.

The lifespan of a flat roof depends on the type of roofing and its maintenance. Bitumen lasts an average of 25-30 years, EPDM rubber even 40 years, and a well-maintained green roof can last up to 50 years.

The cost depends on the material. Bitumen is the most affordable option, while EPDM and green roofs are more expensive but last longer.

You should replace your flat roof if you discover cracks, blisters, leaks, or loose seams. Even if the roof has reached its maximum lifespan, replacement is recommended to prevent damage and costs.

Bitumen is an excellent and affordable choice for a flat roof. Looking for an extra-long lifespan and less maintenance? Then EPDM is a very suitable option. For added insulation and sustainability, you can opt for a green roof.

Check your flat roof at least twice a year, preferably in spring and autumn. This prevents blockages and wear and tear, and extends the lifespan of the roof covering.

Yes, it's wise to invest in roof insulation immediately when maintaining or replacing your roof. This increases comfort in your home and significantly reduces your energy costs.

Koning Dakwerk repaired the fascia boards and gutters at our home in Maassluis. It looks great again, and everything was explained clearly. Communication was pleasant and clear.

During the roof cleaning and coating process, Fatih took the time to explain everything step by step. The difference between before and after is striking. We also received tips for keeping the roof cleaner longer. It's great that they really think along with you.
