How We Trace & Fix A Metal Roof Leak
On metal roofs, the leak you see inside is almost never where the water is entering — it is where the water ends up.
Water entering at a failed end lap travels along purlins and liner sheets, then drips through the nearest opening in a ceiling — metres from the true breach. That is why simply painting over a stain, or resealing the spot directly above the drip, only works until the next rain. Proper metal roof waterproofing begins with understanding the roof's water paths.
The Repair Process, Step By Step
- Stop active ingressWhere water is entering production or stock areas, temporary sealing or diversion is done on the first visit so business impact stops immediately.
- Trace the true entry pointReview of the roof plan, flow lines and joint history; moisture mapping and water testing where the entry isn't obvious.
- Diagnose the failureWhich detail failed and why — end laps, back-out screws, gutter joints, skylight calks, duct vibrations. Never assume the obvious answer.
- Seal with EPDMCured EPDM and German bonding adhesive on the failed details; fasteners replaced where their holes have widened; brittle skylight panels replaced.
- Verify with water testTargeted hose test on the repaired details during pre-rain season, or allow natural rain verification on a live roof.
- Document the resultRepairs recorded with before/after photos; warranty issued on treated zones; recommendations for the remaining roof system noted honestly.
Built For Live Industrial Sites
Repair visits inside Jebel Ali, JAFZA, DIP and Sharjah industrial areas often cannot interrupt production. We schedule noisy or crane-dependent work in line with your shift plan, keep safety lifelines installed, and deliver the repair in phases that keep at least one roof access fully safe. Emergency call-outs inside the UAE run under a documented escalation process — call +971 55 772 3750 at any hour.
When Repair Is Not Enough
Repeat leak — same failure point
The detail failed again because the root cause wasn't addressed (usually wrong system for the joint movement, or no preparation underneath). We re-open the zone, prep correctly and apply EPDM properly the second time — and tell you the story of the previous fix honestly.
Why end laps fail repeatedlySystemic failure — many joints failing
If survey shows a third or more failure rate across joints, the economical long-term answer is a full metal roof waterproofing system — one specification, one warranty, one visit schedule — instead of one emergency call-off after another.

Emergency calls are monitored 24/7. Within Dubai city — Al Quoz, Al Qusais, Dubai Investment Park and older industrial streets — technicians can typically attend the same day. The first visit stops active water ingress; full re-sealing is scheduled around your operations.
Because water travels. On a pitched metal roof, water enters at an end lap or gutter joint and runs along the purlins, liner sheets and insulation until it finds a low point to drip through — often metres away from the entry. Tracing uses the roof geometry, not just the stain, which is why our survey checks the fall lines first.
Localised repair is exactly what targeted EPDM work is for — end laps, gutter joints, skylight frames and duct boots can be sealed individually. If survey shows the roof is systemically failing (>30% of joints open), we will say so and quote a full system instead of selling spot repairs that fail next season.
EPDM repair works carry the same 5-year warranty basis as full installations, issued against the specification for the treated zones. Full-roof systems are extendable to 10 years with maintenance.
Yes. Pre-rain-season stabilisation is a common request in November–December: high-risk joints are sealed, drains cleared and a rollback plan set for the full system in the new year. It is documented as interim works, separate from the main warranty.
Red flags: water entering stock areas, electrical rooms or production floors; drips recurring within days of a previous repair; multiple ceiling stains in different bays; gutter joints actively overflowing. Any of these justify an urgent call — the survey will confirm the right class of work.
