For this project in Zeewolde, we completely renovated a flat roof. The existing roof structure was due for replacement, after which the old roof was carefully removed. Subsequently, the roof was rebuilt with a modern insulation layer and finished with durable 2-ply bitumen roofing. The photos clearly show that the roof has been given a sleek, even finish, with the seams, upstands, and roof edges neatly finished for a long-lasting watertight result.
New roof extension with insulation
A good roof renovation starts with a solid foundation. After the old roofing was removed, the roof was fitted with new insulation. This not only improves living comfort but also limits energy loss through the roof. Subsequently, a two-layer bitumen system was applied, known for its high durability and excellent protection against rain, wind, and temperature fluctuations.
During the work, close attention was paid to the finishing of the upstands, the roof edges, and the connections around the rainwater drain. These details are crucial for the lifespan of a flat roof and significantly reduce the risk of future leaks.
Sleek and durable finish
After the installation of the new roofing, the entire roof was inspected for finish and watertightness. The photos show a sleekly finished roof surface with neat bitumen sheets and carefully executed connections. Thanks to the new insulation and the high-quality 2-layer bitumen roofing, the roof is once again fully prepared for the changing weather conditions in the Netherlands.
With this roof renovation in Zeewolde, the home once again features a reliable and durable roof structure. Thanks to the combination of a renewed roof structure, improved insulation, and a professional finish, the flat roof is ready for years of trouble-free use.
