For this project in Alkmaar, we carried out work on the flat roof of an existing dormer. The dormer is situated directly next to the pitched roof of the house. The existing roof has been overlaid, meaning the roof surface has been provided with a new layer of roofing, without mentioning any additional work here that is not apparent from the project details. The renewed roof surface is clearly visible in the photos, including the raised finish along the outer edges.
New roofing over the existing roof
New grey roofing has been installed over the flat roof. The various strips and seams are visible across the entire roof surface. Along the edges, the roofing slopes upwards, ensuring that these sections are also included in the new finish.
Particular attention is visible at the connection between the flat roof of the dormer and the adjacent pitched roof. During work on existing flat roofs, overlaying can be part of a broader roof renovation, depending on the condition and structure of the roof in question.
Neatly finished roof surface and roof edges
After the overlay, the new roofing forms a single continuous surface across the flat roof. The strips join together, and a raised edge finish is visible along the outside. The roofing also continues around the corners.
The photos also provide a clear picture of the transition to the existing pitched roof. As a result, the renewed flat roof has been neatly fitted between the existing roof sections of the house. Periodic inspections can be carried out to check these types of connections and roof surfaces. roof inspection be carried out.
