Location: Purmerend. Executed by DB Dakwerken.
The condition of the substructure partly determines how a worn roof is addressed. At this home in Purmerend, the base was still usable, while the outer covering had several weak spots. Therefore, the roof was renewed by applying an extra layer of bitumen.
Utilizing the existing base
Prior to the overlaying, DB Dakwerken inspected and prepared the roof. Subsequently, the new bitumen covering was applied to the existing roof. Removing the entire old roof structure was not necessary with this approach.
The finishing was not limited to the roof surface. Seams, edges, and penetrations have been carefully connected and additionally reinforced. In this way, the new waterproofing layer also connects to the vulnerable transition points.
A new outer layer
The renovation will be completed in February 2026. The house features renewed roofing, while the sound underlying structure has been preserved. DB Dakwerken supplies this version with a 10-year warranty on materials and workmanship.
