Expert Advice on Flat Roof Water Ingress Repair

Garage flat roofs are prone to water ingress if not maintained properly. Given that this roof in Frome is covered with corrugated concrete sheeting and has already been patched in places, it is likely that the existing repairs are failing, or there are new cracks allowing water to penetrate. Addressing the issue quickly is essential to prevent further damage to the structure and interior.

Common Causes of Water Ingress in Flat Roofs

Several factors may be contributing to the leaks in your flat roof:

Age and Wear: Over time, corrugated concrete and fibreglass coatings can crack or degrade.
Failed Patches: Temporary repairs may not have fully sealed the leaks.
Seam or Joint Failure: Water may be seeping in through gaps in overlapping sheets.
Poor Drainage: Standing water on a flat roof can lead to infiltration.

Steps to Repair a Leaking Flat Roof

Repairing a flat roof with corrugated concrete sheeting typically involves the following steps:

Inspection: Checking for cracks, gaps, and weak points where water is penetrating.
Surface Preparation: Cleaning and drying the affected area to ensure proper adhesion of repair materials.
Sealing Small Cracks: Applying a waterproof sealant or roofing compound over minor gaps.
Replacing Damaged Sheets: If sections of the corrugated concrete are too damaged, they may need to be replaced.
Applying a Protective Coating: A waterproof membrane or fibreglass overlay can be applied for long-term protection.

Repair vs. Full Roof Replacement

Since the roof has already been patched in places, it’s worth considering whether a full replacement is necessary. Options include:

Short-Term Repair: Applying more patches and sealant for a temporary fix.
Re-covering the Roof: Adding a new waterproof layer over the existing structure.
Full Replacement: Removing the old corrugated sheeting and installing a modern flat roofing system (e.g., EPDM rubber, GRP fibreglass, or bitumen felt).
