Flat roofing specialists in Waterlooville. Waterlooville's 1970s and 80s development boom produced a large stock of rear extension flat roofs now approaching or past their original design life. GRP, EPDM and felt specified correctly for Waterlooville's local conditions.
GRP fibreglass is specified on most Waterlooville 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 Waterlooville 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.
Waterlooville's 1970s and 80s development boom produced a large stock of rear extension flat roofs now approaching or past their original design life. We specify GRP fibreglass for most Waterlooville 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. Waterlooville's 1980s extension decks in Waterlooville are frequently showing edge softness — chalk downland frost cycles create wood movement that causes edge seal failure earlier than in more stable coastal climates. 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 Waterlooville's conditions. We give honest advice on which system is right for the specific location.
