Flat roof repairs

We repair flat and low-slope roofs in Perth. We inspect the roof material, joints and drainage before recommending a suitable repair.

Standing water and leaks on a flat roof

Flat roofs can use metal sheets, membranes or other existing finishes, so there is no single repair method for every roof. Standing water can point to a drainage issue but does not establish where a leak starts. We also check roof openings, edges and wall junctions. Tell us whether water remains after rain; a photo alone cannot confirm the cause.

Flat roof repairs suited to the material and drainage

Identify the roofing material and previous treatments and inspect the leak area, outlets and nearby roof connections.
Agree the repair area and suitable materials. List outlet clearing, drainage changes and repairs to the roofing separately.
Check the repairs and explain what has been retained, what is not included and whether more extensive work is needed.

Finding the leak and checking drainage

The existing roof material

We identify the roof covering, previous treatments and connections first. The repair materials and method must suit what is already on the roof.

Ponding and the source of a leak

Standing water alone does not show where rain gets in. We inspect the surface, drainage, wall junctions and roof openings before recommending repairs.

Drainage and roof-to-wall connections

These Perth photos show internal drainage and adjoining roof and wall connections. On a flat roof, we assess those junctions alongside the roof surface and outlet before recommending repairs. The repair material must suit the existing roof covering. The photos illustrate these details, rather than a whole flat-roof replacement.

Tell us your suburb, what needs attention and the roof material, if known. We assess the roof on site. Existing photos are optional; do not climb onto the roof or enter an unsafe roof space to take them.
