Professional repair and waterproofing of corrugated metal roofs across Dubai. We fix leaks, rust, screw holes and corrosion with a permanent EPDM system — not a temporary patch. Free site inspection within 24–48 hours.
Corrugated metal roof problems in Dubai start small and rapidly escalate. Don't wait until stock, equipment or interiors are damaged.
Water dripping through screw holes or sheet overlaps during rain
Rust and orange staining spreading across corrugated sheets
Old silicone cracking from Dubai's extreme heat cycles
Unbearable heat inside — metal absorbing solar radiation
Repeated patches that fail again within weeks
Lifted or loose sheets around ridge caps and gutters
Corrugated metal roofs are the most leak-prone roof type in Dubai. Silicone patches can't keep up with the relentless heat expansion and contraction. EPDM rubber membrane is the only system that solves this permanently — flexible enough to move with the metal, UV-stable enough to last 20+ years.
It fills every corrugation, covers all screw holes and laps, and is engineered for 120°C+ surface temperatures. No other system comes close.
EPDM is pressed into each corrugation and fully bonded, eliminating every void that water could track through.
Every fastener and overlap is encapsulated. This is where 90% of corrugated roof leaks originate.
Engineered for extreme UAE conditions — won't crack, bubble or delaminate regardless of temperature.
Light-coloured EPDM reflects solar radiation, cutting heat transmission and AC costs significantly.
From first call to final warranty certificate
Every screw, overlap, ridge and gutter inspected and documented with photos.
All corroded areas treated with rust converter, degreased and mechanically cleaned.
Bonding primer applied across the full surface for permanent EPDM adhesion.
Full EPDM rubber sheet pressed into every corrugation. All ridges, gutters and penetrations sealed.
Full water test, before/after photo report, and 5-year warranty certificate on completion day.
Covers materials and workmanship. We return and fix at zero cost if anything fails.
Understanding why your roof is leaking is the first step to fixing it properly.
Rubber washers degrade under Dubai's UV and heat within 3–5 years. A 1,000 sqm roof can have over 2,000 screws — each one a potential leak.
Coastal humidity and industrial pollutants accelerate rusting. Once rust perforates a sheet, water ingress is guaranteed. Early treatment saves the sheet.
Dubai roof temperatures swing 60°C+ daily. This constant movement opens gaps at overlaps and ridges — any rigid sealant cracks within 1–2 seasons.
Overlaps separate as fixings loosen. Water tracks horizontally along corrugations and appears inside the building far from the actual entry point.
Ridge caps face maximum wind uplift, thermal movement and UV. Failed ridge seals cause leaks that appear to come from everywhere along the ridge line.
When gutters block, water backs up against the sheeting. Combined with failed screws, light rain turns into a flood inside the building.
A professional step-by-step walkthrough of the correct process for GI sheet and corrugated metal roof waterproofing in UAE conditions.
Walk the entire corrugated roof surface and mark all screw head failures, end lap separations, side lap gaps, ridge cap cracks, and any rust perforation. In Dubai, never skip this — a leak inside the building can originate up to 10 metres away from where water first enters the sheet.
Apply rust converter to all corroded GI sheet areas and allow full cure. Mechanically clean any loose scale. Skipping rust treatment is the #1 reason corrugated roof waterproofing fails prematurely — water vapour trapped beneath the membrane causes delamination from the inside out.
Corrugated roof end lap sealing is the most critical joint on the entire roof. Clean the lap, apply seam reinforcement tape under pressure across the full width, and prime for EPDM adhesion. End laps and side laps account for approximately 35% of all corrugated roof leaks in UAE warehouses.
Apply a bonding primer formulated for metal substrates across the full corrugated surface. Allow the correct flash-off time before EPDM application — this varies with ambient temperature and is especially important in Dubai's summer months when metal surface temperatures can exceed 80°C.
Roll out EPDM membrane and press firmly into every corrugation profile using a roller. This is the step that requires specialist skill — every trough must be fully bonded with no air pockets. Poor corrugation fill causes bridging, which leads to standing water and eventual membrane failure.
Flood test all repaired areas and inspect under the roof while water is pooled above. Issue a written warranty certificate with before-and-after photo documentation. A professional corrugated roof waterproofing contractor should always provide physical evidence of the completed standard.
Not all waterproofing systems work on corrugated metal roofs. Here's how the three most common options compare in UAE conditions.
| Factor | EPDM Membrane | Silicone Sealant | Modified Bitumen |
|---|---|---|---|
| Lifespan in UAE climate | 20–25 years | 2–5 years | 8–12 years |
| Heat resistance (surface temp) | 120°C+ | 70°C | 80°C |
| Corrugation profile coverage | Full — every trough | Spot only | Not suitable |
| End lap & screw head sealing | Complete encapsulation | Partial only | Not effective |
| Thermal expansion tolerance | 300%+ elongation | Cracks <1 season | Cracks in 2–4 years |
| Suitable for occupied warehouse | Yes — no fumes | Yes | No — torch-applied |
| Written warranty available | 5–10 years | Rarely offered | 2–5 years |
