Location: Purmerend. Executed by DB Dakwerken.
For this residential roof in Purmerend, the renovation challenge lay in the bitumen covering. Wear, cracks, and minor leakage made replacement necessary. Because the supporting structure was still in good condition, it could be retained when applying a new layer.
Preparation and processing of the bitumen
DB Dakwerken started by inspecting and cleaning the roof. Subsequently, the surface was overlaid with bitumen. The edges and seams were joined to the new covering, and vulnerable connections were additionally reinforced.
The roof was renewed in this way without removing the entire existing structure. The sound base remained usable, while the surface and connections received a new waterproof finish.
Completion of the renovation
Since March 2026, the house has featured a renewed outer layer covering the worn roofing. This approach extends the lifespan of the existing roof. DB Dakwerken provides a 10-year warranty on materials and labor for this project.
