For this home in Amersfoort, we renovated an existing flat roof using a roof overlay. Instead of completely removing the existing roofing, a new bitumen top layer was applied over the existing structure. This method significantly extends the lifespan of the roof and avoids unnecessary demolition work. The photos clearly show that the roof has been given a neat and uniform finish, with the roof edges also being completely renewed.
New bitumen top layer and zinc capping strips
After a thorough inspection of the existing roofing, the roof was prepared for the new finish. Subsequently, we applied a high-quality bitumen top layer, which provides watertight and durable protection against various weather conditions. All seams and connections were carefully finished to achieve a reliable end result.
In addition to the new roofing, new zinc flashing has been installed around the perimeter of the roof. These not only provide a neat and modern appearance but also protect the roof edges against moisture and wear. The neatly installed flashing is clearly visible in the photos, giving the entire roof a tidy and high-quality finish.
Sustainable renovation with attention to detail
With a roof overlay, the details are at least as important as the roofing itself. Therefore, extra attention has been paid to the finishing of the upstands, corners, and transitions to the roof edges. By carefully executing these components, the roof remains watertight for a long time and the risk of future leaks is significantly reduced.
The combination of a new bitumen top layer and zinc flashing makes this renovation a sustainable solution that ensures the roof will last for many years to come without problems. Moreover, the existing roof structure was preserved, allowing the work to be carried out efficiently without compromising on quality.
With this roof lowering in Amersfoort, the home once again features a sleekly finished and well-protected flat roof. Thanks to the new bitumen roofing and the durable finish with zinc flashing, the roof is ready for many years of reliable use.
