Roofing in Rotterdam
A flat roof is only as good as its detailing. We use two-layer bitumen roofing and pay extra attention to upstands, penetrations and connections, because that is where almost all leaks start.

Good to know
Replacing a flat roof is the perfect moment to insulate as well. A well-insulated roof makes a noticeable difference to your energy bill and keeps the upper floor cooler in summer. We build the roof up with insulation to current requirements and roofing that stands up to Dutch weather.
A dormer instantly gives your attic more headroom, light and usable space. We install dormers with a clean finish in uPVC or panel material and connect them watertight to the existing roof.

Frequently asked questions
How long does a bitumen roof last?
A well-laid two-layer bitumen roof lasts 20 to 25 years on average with normal maintenance. Keeping outlets clear and checking connections regularly helps.
Is a dormer permit-free?
A dormer on the rear roof slope is permit-free under certain conditions. At the front or on a listed building a permit is usually required. We look at this with you during the survey.
My roof is leaking. What should I do?
Call or WhatsApp us, ideally with a few photos of the spot. We come and inspect, trace the cause and repair it. The problem is often at an upstand, penetration or outlet.
