Flat roofing in Skerton primarily addresses the back addition extensions of the Victorian riverside terraces and, on the post-war estate streets, the garage and outbuilding flat roofs that were added during the 1970s and 1980s. The riverside location creates a specific challenge for flat roofing: the elevated humidity of the Lune north bank means that flat roof surfaces take longer to dry between rain events, moss establishes faster on the drainage outlets and upstand edges, and any drainage deficiency that causes ponding water creates conditions where the membrane is never fully dry from October through April.
The most consistent flat roofing failure we attend in Skerton is outlet blockage on back addition roofs whose outlets have not been maintained. A blocked outlet on a flat roof in Skerton's rainfall can fill the available ponding depth — typically 50 to 100mm between the deck surface and the upstand top — within a single sustained rain event. When water reaches the upstand top it overflows onto the wall face below and in the most severe cases flows back through the wall junction and down the internal face. Regular outlet clearing — twice yearly at minimum — is the single most important maintenance activity for any Skerton flat roof.
GRP fibreglass is the correct primary specification for flat roof replacement on Skerton's riverside terraces. The seamless application and the non-organic nature of the cured resin surface means GRP does not support moss growth in the way that felt does — the organic binders in traditional felt bitumen provide a nutrient base for moss and algae that GRP lacks. In Skerton's elevated riverside humidity, the difference in moss accumulation rate between a felt flat roof and a GRP flat roof over a 10-year period is visible.
The back additions of Skerton's Victorian terraces were typically built with a single central outlet connecting to a vertical downpipe through the addition wall. This design is adequate for a roof in good repair with a cleared outlet. When the outlet becomes partially blocked with debris, the single-outlet arrangement has no overflow provision — water simply rises to the upstand level and overflows into the wall junctions. We specify overflow provision as a standard addition to all single-outlet Skerton flat roof replacements: a secondary overflow at upstand height that discharges visibly and provides early warning of outlet blockage.
Where Skerton flat roof replacement involves a larger area than a standard back addition — a full-width rear extension or a large outbuilding roof — EPDM rubber membrane is an appropriate alternative to GRP. EPDM is a single sheet applied across the full surface without seams on areas up to approximately 20m², which eliminates the lap joints that are the primary failure points on multi-piece felt systems. We advise on the relative merits of GRP versus EPDM for each Skerton flat roof application based on the specific size, geometry and access conditions.

In Skerton, the primary flat roofing issue relates to the Victorian terraces near the river, post-war estates further north housing stock: elevated valley blockage rates from moss growth on riverside victorian terraces, generating more internal leak calls per property than equivalent sheltered city streets. This is what we attend to most consistently in the area.
