This project addressed a complex leaking issue caused by structural sagging and water retention on an aging lead roof. Rather than a temporary patch, we implemented a structural over-boarding solution designed to permanently correct the roof’s fall and drainage.
Technical Scope of Work:
Structural Framing: We engineered and installed a bespoke internal timber framework over the existing lead surface. This frame was precision-leveled to create a consistent pitch, resolving the structural “dips” found in the original roof.
Over-Boarding: The new frame was topped with high-grade roofing boards, creating a solid, uniform substrate. This elevated surface provides a clean platform for the final waterproof layer while reinforcing the overall area.
Drainage Correction: By altering the roof’s geometry, we successfully eliminated water pooling—the primary cause of the previous leaks.
Internal Gutter Integration: We fitted a dedicated internal gutter system specifically to manage the new runoff. This ensures that rainwater is channeled efficiently away from the property, providing a long-term, leak-free solution.
Project Outcomes:
Zero Pooling: The new pitch ensures that water cannot sit on the surface, preventing the degradation of materials.
Enhanced Integrity: The internal frame adds significant strength to the roof structure without the need for a full, invasive tear-down.
Optimized Water Management: The custom guttering provides a controlled path for heavy rainfall, protecting the interior of the property.
