Metal Roof Waterproofing in Dubai & Across the UAE
Metal roof waterproofing is used on metal roofs, which are lightweight, durable, and common in warehouses, factories, and site offices. But without proper waterproofing, they’re vulnerable to rain intrusion, corrosion, and noise issues.
At Salman Syed Technical Services, we use GRP lining, PU coatings, and specialized sealants to protect metal roofs from the UAE’s harsh climate, ensuring weather-tight performance and a longer lifespan.
Why Metal Roof Waterproofing Is Essential in the UAE
Metal roofs expand and contract with temperature swings, which causes sealant joints and fasteners to loosen over time, leading to leaks, rust, and corrosion. Effective waterproofing stops water ingress, reduces maintenance needs, lowers noise from rain, and improves thermal comfort under the roof.
If you’re looking for solutions beyond metal, explore our complete roof waterproofing services.
Waterproofing Methods for Metal Roofs
We select the best method based on roof profile, exposure, and access:
GRP Lining Systems
Tough, seamless lining ideal for metal decks and gutters, offers high corrosion resistance.
PU Coating Systems
Flexible liquid-applied membranes that adhere well to metal sheets, seal seams, and resist UV.
Sealant & Flashing Solutions
High-grade sealants and metal-specific flashing installed around fasteners and roof transitions.
