Standing water on a flat roof — The Hague, South Holland
If water is still pooling on your flat roof 48 hours after the last rain, you have a ponding problem. Flat roofs are designed with a slight slope to drain, but sagging decking, clogged internal drains, or shifted insulation can create low spots where water sits. Prolonged ponding accelerates membrane deterioration, adds hundreds of pounds of dead load to the structure, and eventually causes leaks. A roofer can identify the cause — whether it's a drainage issue, structural deflection, or membrane failure — and restore proper drainage with tapered insulation, additional drains, or membrane repair.
Why this is common in The Hague
The Hague's historic government buildings and palatial residences have complex rooflines requiring specialized expertise. Coastal wind-driven rain and salt spray accelerate roofing degradation. The Scheveningen seaside district has particularly aggressive weathering conditions.
