What flat roof work do we do in Folkestone?
Single-ply membrane roofing
If a flat roof in Folkestone has poor falls and ponding, a single-ply re-roof with tapered insulation can correct both problems at once. The tapered boards build the fall into the insulation, and the membrane is laid over the top, with outlets set at the new low points.
GRP fibreglass roofing
For a garage or extension in Folkestone that doubles as a step-out space for window cleaning, GRP gives a firmer footing than a rubber membrane. With an anti-slip topcoat it handles light, occasional use, though a full terrace needs its own specification and, in many cases, planning permission.
Balconies and roof terraces
A roof terrace in Folkestone may be re-waterproofed when the owners want to change the finish, swapping old tiles for decking or porcelain on pedestals. Lifting the surface exposes the membrane, and replacing it then avoids having to lift the new finish again later.

What flat roofs are typical in and around Folkestone?
In a large town like Folkestone flat roofs are mostly on lock-up garage blocks on estates and low-rise post-war blocks of flats. The climate is part of the brief. Much of the South East sits in the drier Thames catchment at roughly 730 mm of rain a year, so the usual failures are at joints, upstands and outlets rather than from sheer volume of rain. Approximate 1991–2020 regional averages based on Met Office data.
Who approves flat roof work in Folkestone?
Where approval is needed it goes to Folkestone and Hythe District Council building control, or a registered building control approver. Replacing more than half of a roof over a heated room usually counts as renovating a thermal element, so it is insulated to current standards and notified to building control. How the rules work.
