Seepage is typically caused by poor waterproofing, cracks in walls or roofs, inadequate drainage systems, or damaged plumbing, and can also occur from water accumulation during heavy rain finding its way through weak points.

Torch applied membrane is a bituminous sheet that is heat-welded to the substrate using a torch, creating a fully bonded waterproofing layer ideal for flat roofs.

Waterproofing your roof involves applying a protective coating or membrane that prevents water from seeping through. Common methods include liquid waterproofing membranes, bituminous coatings, or polyurethane-based systems. The surface must be cleaned and cracks repaired before the waterproofing material is applied evenly to create a watertight seal.
