What flat roof work do we do in Dunoon?
Extension and kitchen roofs
Ponding against the house wall is a common reason for replacing an extension roof in Dunoon. When the deck dips near the wall or the fall runs the wrong way, water sits against the abutment and eventually gets in. A new roof with corrected falls moves the water to the gutter.
Single-ply membrane roofing
On exposed sites in Dunoon and elsewhere, mechanically fixed single-ply is specified with a fixing pattern based on wind uplift, with extra fasteners at corners and edges. That makes it a strong option for commercial roofs where wind loads are a concern.
Torch-on felt roofing
Torch-on felt is widely specified for blocks of flats and HMOs, in Dunoon as elsewhere, because the system is well understood, widely repairable and governed by a British Standard code of practice. Three-layer builds with insulation are common on larger, multi-occupied roofs.

Approximate 1991–2020 regional averages based on Met Office data.
