GRP fibreglass and EPDM flat roofing for Long Stratton extensions, garages and outbuildings. Correct falls, proper drainage, 10-year guarantee. Free quotes.
Flat-roofed extensions and garages are common across Long Stratton's Period High Street properties with clay pantile and plain tile, 1930s–1960s housing on Church Road and Swan Lane, modern concrete tile estates on Windmill Way and Applegate. Most of the flat roofs on Long Stratton's post-war and 1970s–80s housing are now reaching or past the end of their original felt covering's serviceable life — and many have been re-covered once already with materials that are themselves now ageing.
We install GRP fibreglass (our recommended system for most Norfolk residential applications), EPDM rubber and high-performance felt. GRP performs best in Long Stratton's conditions — Exposed South Norfolk farmland with no valley shelter. Prevailing westerly and southerly gales track unimpeded across the Tas valley, generating significant ridge and hip uplift stress on all property types. — because it tolerates freeze-thaw cycling and wind-driven rain better than felt, and requires minimal maintenance over its 25+ year design life.
Correct falls are non-negotiable on Long Stratton flat roofs. The Exposed South Norfolk farmland with no valley shelter. Prevailing westerly and southerly gales track unimpeded across the Tas valley, generating significant ridge and hip uplift stress on all property types. conditions here mean that standing water degrades flat roof membranes faster than in sheltered locations. We design all installations with minimum 1:80 falls to outlets, and specify outlet sizing appropriate to the roof area and local rainfall intensity.
The most common finding on Long Stratton flat roof replacement jobs is wet or rotten decking beneath the existing covering. On the 1970s and 1980s chipboard decks common across Long Stratton's post-war housing, failed felt allows water to sit on the deck for months before the leak becomes visible inside. We survey deck condition as part of every flat roof quote — this is not an optional extra.
GRP and EPDM flat roofs require minimal maintenance — an annual outlet check is sufficient on most Long Stratton properties. The main risk in Long Stratton is leaf and debris accumulation in outlets, particularly on properties close to hedges and trees. We recommend annual October clearing on all Long Stratton flat roofs before the main rainfall season.

Call 0160 339 6191Long Stratton is a ribbon village strung along the old A140 south of Norwich. The first thing to establish is whether you are looking at an isolated repair or the early signs of a roof past its serviceable life.
When it is not the answer: If a sound GRP or EPDM roof has a single failed detail, a targeted repair beats a full re-cover — and if the "leak" is condensation, a new covering alone will not fix it. Read the full guide.
On a Long Stratton flat roof we check the deck, falls and ventilation first, because the roadside period stock brings lead and heritage matching close to a busy frontage; the modern estates behind show standard concrete-tile wear. — and the “leak” is often condensation, not a hole.

GRP fibreglass is our recommended choice for most Long Stratton residential flat roofs. It performs well in Norfolk's climate conditions — particularly the freeze-thaw cycles and wind-driven rain — with a 25+ year design life and minimal maintenance.
Most garage and extension flat roofs in Long Stratton are completed in a single day. Roofs requiring deck replacement typically take 2–3 days. The old coaching-road frontages along The Street are tight to the carriageway.
We always strip back to inspect the deck. On Long Stratton's older housing stock — much of it with chipboard decks — trapped moisture frequently causes deck deterioration that must be addressed before the new covering goes down.
Re-roofing an existing flat roof is permitted development in most cases. New flat roof extensions may require planning. We advise on this as part of every Long Stratton flat roofing survey. Open South Norfolk farmland either side of the village exposes roofs to prevailing wind and driving rain.
GRP fibreglass has a design life of 25+ years and carries a 20-year material guarantee when installed by an approved applicator. In Long Stratton's climate GRP outperforms felt because it does not crack from thermal movement within its design parameters.
Isolated blisters or cracks on a felt roof can sometimes be repaired if the deck beneath is sound. If the covering is cracked throughout, the deck is wet, or the roof has been repaired multiple times already, replacement is more cost-effective. We assess this at survey. The old coaching-road frontages along The Street are tight to the carriageway.
Re-roofing an existing flat roof is permitted development in most cases. Converting a pitched roof to flat, or adding a new flat-roofed extension, may require planning permission depending on size. We confirm the planning position as part of every survey.
The condition of the deck beneath the existing covering determines the cost and specification of any flat roof replacement. Original 1970s and 1980s chipboard decks on Norwich rear extensions are frequently wet or structurally compromised by the time the covering visibly fails — water has been entering slowly for years before the ceiling stain appears. We inspect every deck before quoting and include deck replacement in the quote where needed, priced per square metre. A flat roof replacement that goes over a compromised deck will fail early regardless of the quality of the new covering.
Flat roof drainage is the most commonly underspecified element on residential installations. A flat roof needs a minimum 1:80 fall to drain completely — any lower and water pools, which accelerates covering degradation regardless of system type. Outlets must be sized for the catchment area and local rainfall intensity. Norwich receives approximately 600mm of rainfall per year, predominantly October–March. We design falls and size outlets on every installation as part of the specification, not as an afterthought.
