Daylight that waterproof stays

By Smienk Dakwerken

Where do things go wrong most often with a skylight or roof dome? At the connection to the roof covering. A window is quickly installed, but without proper leadwork and flashing, it starts to leak after a few years.

Therefore, we not only install the window, but also finish the connection to the roof tiles or bitumen roofing professionally finished. On a flat roof, we install skylights and rooflights with an upstand that neatly drains the water. This way, you get light inside without the risk of moisture.

skylight or beam of light on a flat roof

Flat roof

On a flat roof, a skylight or roof lantern brings in a surprising amount of daylight. We install them on a sturdy curb, with a watertight connection to the bitumen roofing. This way, you prevent leakage around the dome, precisely the place where things go wrong with faulty workmanship.

due for replacement

We replace an old skylight that leaks, lets in drafts, or no longer closes properly with a new, well-insulated model. This can often be done within a day, after which your roof is fully sealed again.

Excellent roofing work and craftsmanship. The collaboration went well; often things don't go according to plan on projects, but we resolved it perfectly. Thanks also for the extra service; we got the unblocking of another gutter included, which saves us some climbing around. I look forward to having them back for my next roofing project.
