Flat Roof Repairs & Leak Stopping | GRP Roofing Specialists
Flat roofs are one of the most common sources of leaks in commercial and managed properties. Kilmal specialises in flat roof repairs using GRP (Glass Reinforced Plastic) — a durable, seamless solution that stops leaks permanently and protects your building long term.
We diagnose the root cause, apply the right solution, and restore watertight integrity — first time.
Why Professional Flat Roof Repair Matters
A leaking flat roof rarely resolves itself. What starts as a small defect — a failed membrane joint, cracked felt, or deteriorating flashing — can quickly allow water ingress that damages ceilings, walls, insulation and electrical installations.
Kilmal provides structured flat roof repair solutions including:
-
Detailed flat roof inspections
-
Thermal imaging surveys to locate hidden moisture
-
Leak tracing and root cause identification
-
GRP flat roof repairs and full overlays
-
Emergency leak stopping and temporary weatherproofing
-
Preventative maintenance strategies
Our engineers work safely and efficiently across live commercial environments, minimising disruption while permanently resolving the problem.
Our Roofing Repair Process
-
Inspection & Condition Assessment We carry out a thorough inspection of your flat roof covering, flashings, upstands, drainage outlets and penetrations to assess the extent of any damage or deterioration.
-
Thermal Imaging Leak Detection Using thermal imaging technology, we locate trapped moisture and hidden defects beneath the roof surface — identifying exactly where water is entering without unnecessary intrusive investigation.
-
Root Cause Identification We determine whether the issue stems from membrane failure, cracked or perished felt, flashing defects, failed upstands, blocked outlets or structural movement — so we fix the actual problem, not just the visible symptom.
-
GRP Repair or Overlay Where appropriate, we apply a GRP repair or full GRP overlay to deliver a seamless, watertight finish. For isolated defects we can carry out targeted GRP patch repairs; for roofs with widespread deterioration we recommend a full GRP overlay for a permanent solution.
-
Validation & Reporting We provide clear documentation of work completed, including before and after records, to confirm restored watertight integrity and support your maintenance records.
Thermal Imaging for Roofing Repairs
Thermal imaging plays a critical role in modern roof diagnostics.
It allows us to:
• Detect moisture beneath membranes
• Identify insulation saturation
• Pinpoint heat loss areas
• Reduce unnecessary strip-out works
This technology improves accuracy, reduces disruption and ensures repairs are focused precisely where needed.
