Most flat roofs in the capital fail because they were installed with outdated materials or poor falls. When water sits (ponds) on a roof for more than 48 hours, it begins to degrade the surface, eventually finding its way into your joists.
We Diagnose and Fix:
"Ponding" Water: Correcting the "fall" of the roof so rainwater flows directly into the gutters.
Thermal Cracking: Repairing solar-damaged felt that has become brittle and split.
Blistering & Bubbling: Identifying trapped moisture within the roof's layers.
Failing Perimeter Edges: Resealing the junctions where the roof meets the brickwork or fascia.
Internal Condensation: Improving ventilation to prevent timber rot from the inside out.

Standing water is the #1 enemy of a flat roof. While a small amount of evaporation is normal, deep pools indicate that the "falls" (the slope) have subsided or were never correct. We can often fix this by installing "tapered insulation" or "firring strips" to redirect water without needing to rebuild the entire structure.
Yes, but we assess the "substrate" (the wood underneath) first. If the previous leaks have rotted the decking, a new patch will eventually fail. We use moisture probes to ensure the timber is dry before we apply any new high-performance membranes.
It depends on usage. GRP is "hard" and better for balconies with foot traffic or where aesthetics matter. EPDM is "flexible" and better for large extensions where the building might move slightly over time. During our free survey, we’ll recommend the best fit for your specific property.
This usually means the membrane has "delaminated" or pulled away from the insulation or decking. In London’s windier months, this can lead to the roof acting like a sail and eventually tearing. We can mechanically fix or re-bond these sections to silence the roof and secure it.
Londoners love outdoor space! If your structure is strong enough, we can install "root-resistant" membranes specifically designed for green roofs or heavy-duty GRP for roof terraces. We can advise on the structural requirements during our inspection.
