Flat roofing specialists in Southsea. Loft conversion flat roofs on Southsea terraces face the most aggressive UV and salt exposure on Portsea Island. GRP is the only specification we use on Southsea flat roofs — EPDM is acceptable on sheltered rear positions only. GRP, EPDM and felt specified correctly for Southsea's local conditions.
GRP fibreglass is specified on most Southsea flat roofs particularly south and west-facing positions with direct sun and salt exposure. EPDM for larger areas. Standard felt not recommended for exposed positions.
We survey the deck as part of every Southsea flat roof survey. Any softness, rot or structural movement is identified and included in the quote upfront. No mid-job surprises.
GRP from 95 pounds per m2 with a 25-year guarantee. EPDM from 75 pounds per m2 with a 20 to 25-year life. Standard felt from 50 pounds per m2 with a shorter coastal life. System must be correct for position.
Loft conversion flat roofs on Southsea terraces face the most aggressive UV and salt exposure on Portsea Island. GRP is the only specification we use on Southsea flat roofs — EPDM is acceptable on sheltered rear positions only. We specify GRP fibreglass for most Southsea 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. Southsea's seafront properties show accelerated deck degradation from the combination of UV, salt and moisture. Deck replacement is more common here than in any other area we work. 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 Southsea's conditions. We give honest advice on which system is right for the specific location.
