Metal Roof Leak Repair, Rust Treatment & Flashing Fix

Why Metal Roofs Fail Quietly Before You See A Stain

RLR Roofer is a Kuala Lumpur metal roofing specialist with over 10 years of experience and 500+ completed jobs across the Klang Valley. We focus on metal roof leak repair for zinc, metal deck, and industrial panels, treating rust at the source instead of painting over it.

Unlike tile roofs, which tend to announce their failure with a dramatic drip, metal roofs fail slowly and silently. A single rust spot, a degraded screw washer, or a lifted ridge cap can let water track underneath for months before it shows on your ceiling. By then, corrosion has already started working on the panels and purlins.

The team at RLR Roofer handles everything from small residential zinc roofs on terrace and link houses in Kepong, Cheras, and Petaling Jaya, through to shop lots in Damansara and full factory and warehouse roofs in industrial Shah Alam, Klang, and Rawang. We treat rust early, replace the right components, and extend your roof’s life by years instead of recommending a premature full replacement.

Common Roof Failures We Fix Across the Klang Valley

• Rust spots and streaks on zinc-aluminium, NS BlueScope, and Lysaght-style metal deck panels, treated with rust conversion, anti-corrosive primer, and a protective topcoat.
• Leaking around screws, where degraded EPDM washers are replaced and fasteners upgraded where needed.
• Lifted or torn ridge cap flashing, re-sealed or replaced with the appropriate overlap.
• Corroded valley and wall flashing, a frequent source of Malaysian monsoon leaks on double-storey link houses and semi-D properties.
• Loose or missing self-drilling screws, often caused by thermal movement and vibration on long factory and warehouse spans.
• Dented or punctured panels, with localised replacement where the structural panels are still sound.

How Our Metal Roof Leak Repair Approach Is Different

Too many metal roof repairs are just a tube of cheap silicone squeezed over the symptom. That does not last in Malaysian UV and heat. RLR Roofer’s metal roof crews work to a higher standard:

• Material-matched fasteners and sealants rated for tropical conditions and for the metal systems we commonly see in Malaysia (NS BlueScope, Ajiya, Lysaght, and generic zinc panels).
• Rust treated at the source, not painted over.
• Flashing detailed properly, not just sealed on top.
• Full inspection of purlins and structural members wherever we can see them.

Transparent Pricing From RM500 Per Repair Zone

Metal roof leak repair starts from RM500 per repair zone for residential jobs in 2026. Larger industrial and factory projects in Shah Alam, Klang, and Rawang are quoted by phase. As with every RLR Roofer job, the RM30 onsite inspection fee is fully waived when you approve the repair, so you always get a real diagnosis before committing.
