Flat roofs for extensions and garages
A flat roof can suit a garage, extension or other building where a compact roof profile is useful. Its form may allow an approach that fits the adjoining building without introducing a large pitched structure. Whether it is suitable depends on the building design, permissions and the construction proposed. It should be treated as a designed roof system, with the same attention to weatherproofing as any pitched roof.
Choosing flat roof materials
Felt, EPDM and GRP offer different installation methods and detailing requirements. Material choice can be considered alongside roof shape, access and the condition of the substrate. Rooflights may also be possible, but their position and kerb details need planning from the start. The benefit is the ability to choose a coherent specification for the project, rather than simply covering the existing deck.
Flat roof drainage and weatherproofing
A flat roof still needs a reliable route for rainwater. Falls, outlets, perimeter upstands and wall junctions all affect performance. Replacement work also creates an opportunity to consider insulation and condensation control. Those elements should be discussed together because changes in the roof build-up may affect thresholds, edges and connections to the existing building.
Flat roof maintenance requirements
Flat roofs are not maintenance-free. Debris can obstruct drainage, and damage to the covering needs attention. Inspecting from a safe position and arranging suitable access for maintenance can help problems be identified earlier. Do not assume a roof is safe to walk on simply because it appears flat; coverings and the structure beneath them may be fragile.
Planning a flat roof installation
For flat roofing on the Isle of Wight, tell us the building type, approximate size and whether you are planning a new roof or replacing an existing one. The useful comparison is the complete proposed system, installation detail and maintenance needs. A material name alone is not enough to judge the finished roof.
