Upon arrival, we initially expected the job to be a straightforward task. However, upon closer inspection, it became clear that the original flat roof had been improperly installed. This poor installation had caused the roof to sweat, ultimately leading to significant structural failure.
To rectify the issue, we fully removed the existing ceiling, rafters, and roof boards. We then installed new rafters with furring strips to create a fall directing water towards the outlet, ensuring proper drainage.
Next, we fitted 18mm OSB followed by a vapour barrier. On top of this, we installed 25mm insulation and an additional layer of 18mm OSB boards, effectively constructing a warm roof system.
To complete the installation, we applied a CosmoFin roofing membrane, ensuring a durable and weather-resistant finish. Finally, we installed trims into the brickwork and sealed all edges with high-quality sealant to ensure a clean, watertight, and professional finish.
