Portchester North's post-war estate carries garage flat roofs similar to other Portsmouth estate areas. Conservation area properties in the castle village may have flat roof sections requiring traditional materials. We specify GRP fibreglass for most Portchester flat roofs — particularly south and west-facing positions where UV and salt exposure are highest. EPDM rubber is our recommendation for larger areas where GRP costs become prohibitive. Standard felt is not recommended for exposed positions in this part of Hampshire.
Before specifying any system, we survey the deck. Portchester's harbour-proximity properties show accelerated deck edge deterioration from salt-laden air, similar to Gosport's exposure profile. We assess deck condition as part of every survey — any softness, rot or structural movement is identified and included in the quote upfront. No mid-job surprises.
GRP fibreglass costs from £95 to £135 per m2 with a 25-year guarantee. EPDM rubber costs from £75 to £100 per m2 with a 20 to 25-year life. Torch-on felt costs from £50 to £70 per m2 but has a 10 to 15-year life in Portchester's conditions. We give honest advice on which system is right for the specific location.
