Repair, overlay or replacement?
We inspect the existing covering, substrate, drainage and roof edges. An overlay is suitable only when the underlying roof is technically sound; trapped moisture or damaged layers may require a different approach.

Bitumen flat roofs in Haarlem
New bitumen roofing and targeted repairs for flat roofs, extensions and garages in Haarlem and surrounding towns.
Details that keep water out
Roof edges, upstands, skylights, outlets and wall connections are part of the assessment. Your quote explains which details and layers will be renewed.
Indicative cost
A bitumen overlay starts from €62.92 per m² including 21% VAT. This assumes a suitable existing covering. Removal, insulation, drainage and difficult access can change the total.
Can you cover the old bitumen?
Sometimes. We first check its condition, adhesion, moisture and the roof structure.
Can a flat roof be insulated?
Insulation can often be combined with renewal. The available height, drainage and condensation risk need to be considered.
How soon can a leak be assessed?
Call Johnny to discuss the urgency and availability. We agree an appointment; we cannot promise a fixed arrival time without checking the situation.
