Flat roofing in Freehold addresses the back addition extensions of the Victorian conservation area terraces. These additions — typically single-storey rear extensions adding a kitchen or utility room to the original two-up two-down floor plan — have flat roofs that were added at various points in the post-war period, with the majority now between 40 and 70 years old. The conservation area context affects the visible external details of these flat roofs — the upstand height, flashing profile and gutter connection are all visible from the rear yards and should be specified consistently with the character of the surrounding Victorian fabric.
The specific challenge for flat roofing in Freehold's conservation area is the junction between the flat roof membrane and the surrounding sandstone masonry. The original Victorian sandstone is porous and lime-pointed — any flashing detail that traps water against the sandstone face creates the same moisture ingress and spalling risk that affects incorrectly pointed chimneys in the area. We specify the upstand and flashing details on Freehold flat roofs with specific attention to water shedding away from the sandstone face rather than toward it.
The upstand junction on a Freehold back addition flat roof involves the waterproof membrane turning up against the original Victorian sandstone of the main house rear wall. This junction must accommodate differential thermal movement between the flat roof structure and the sandstone masonry, must shed water outward rather than channelling it into the sandstone face, and must be specified in materials that are compatible with the lime mortar pointing of the surrounding masonry. We use lead flashing over GRP upstand for all Freehold conservation area flat roof upstand junctions — the lead accommodates movement and sheds water correctly.
GRP fibreglass is the appropriate primary specification for Freehold back addition flat roof replacements. The seamless application eliminates joints at the internal corners and plan changes that are common on the irregular plan shapes of Victorian terrace back additions. The cured GRP surface does not support moss growth in the way felt does, which is relevant in Freehold's north-facing rear yard context where moss establishes faster on shaded surfaces. The GRP system is covered by a 20-year manufacturer guarantee and a 10-year workmanship guarantee from us.
Flat roof replacement in the Freehold conservation area on a standard residential property does not generally require planning consent where the footprint, height and general appearance remain unchanged. The material change from felt to GRP or EPDM is considered a maintenance repair rather than an alteration. Where visible flashings or upstand details are changed in a way that affects the external appearance, we advise on whether notification to the local planning authority is appropriate. Listed buildings in Freehold require listed building consent for flat roof replacement regardless of the extent of work.

In Freehold, the primary flat roofing issue relates to the Victorian and Edwardian (1870–1914) housing stock: nail fatigue on original iron fixings — freehold shares the full victorian nail fatigue profile with bowerham and bulk, compounded by the conservation area requirement to maintain welsh slate specification on all re-roofing work. This is what we attend to most consistently in the area.
