A terrace home in Sendayan, Negeri Sembilan had a long metal roof section where the perimeter lines needed better sealing. The repair focused on the roof edges and end joints so the exposed surface could be protected more effectively.
The Challenge: Metal Roof Edges Were the Main Leak Concern
Rather than the whole roof needing replacement, the issue was concentrated around the outer lines of the metal roof. The side edges and connecting sections were the parts that needed attention, especially where rainwater would pass through during wet weather.
Because this was a long roof span within a row of houses, the work had to stay focused on the affected sections without disturbing the overall roof structure.
Our Solution: Torch On Membrane Along the Roof Perimeter
Before starting the repair, we checked the metal roof layout and prepared the edge sections that needed treatment. This helped create a more even base for the waterproofing layer around the perimeter.
Torch on membrane was then applied along the side edges and end joint areas as part of our roof repair service. The work centred on the roof lines where better sealing was needed around the exposed metal roof section.

The Result: Better Sealing Around the Repaired Roof Section
The repaired roof now has a cleaner membrane finish around the outer edges and connection points. The treated sections have more complete coverage, which helps support better protection across the metal roof area.
