A landed home in Ampang had metal roof and slab sections that needed waterproofing repair. The roof sheets connected to open slab areas, so the main concern was treating the edges, laps and wall junctions where water could enter during heavy rain.
The Challenge: Metal Roof and Slab Areas Needed Better Protection
The metal roof sat beside slab sections and different roof materials, creating several connection points that needed proper treatment. If these areas were not sealed well, water could collect around the edges or move into weaker parts of the roof structure.
The homeowner needed the repair to cover the metal roof edges and the adjoining slab area without leaving gaps between one treated section and another.
Our Solution: Torch On Membrane Applied Across Connected Roof Areas
Our team reviewed the roof layout, checked the affected joints and prepared the metal roof and slab surfaces before membrane installation. The working areas were cleaned and arranged so the membrane could bond properly across the connected sections.
Our team prepared the metal roof edges, nearby slab sections and wall junctions before applying the membrane. The work was carried out under our roof repair service, using torch on membrane to create better coverage across the affected roof areas.
The Result: Cleaner Roof Coverage Around Treated Areas
After the membrane work, the metal roof edges and nearby slab areas were properly covered. The finishing looked cleaner around the wall side, roof joints and connecting areas where water usually finds its way in.
