Flat roofing in Southwold
EPDM rubber, GRP fibreglass and felt flat roofs for extensions, garages, dormers and outbuildings, with proper falls, trims and outlets. In Southwold that usually means working on conservation-area period roofs and pantile and slate cottages, alongside commercial jobs around High Street retail. East Suffolk Council is the local authority, and we'll flag anything that may need consent before we start.

Typical jobs on conservation-area period roofs
Period seaside cottages and conservation-area roofs.
Driven rain at abutments
Rain arriving horizontally finds gaps that vertical rain never would. On conservation-area period roofs it is chimneys, dormer cheeks and side abutments we check first.
Split and blistered felt
Old bitumen felt splits at movement joints and blisters where trapped moisture expands. Overlaying rarely fixes either.
Matching historic coverings
Period and listed buildings near Southwold need like-for-like coverings and correct detailing; we'll flag where East Suffolk Council consent may be required.
Failed upstands and trims
Most flat-roof leaks start at the edges — upstands, drip trims and the junction with the main wall — not in the middle of the roof.
Coverings suited to Southwold
- Torch-on felt systems
- Multi-layer bitumen for larger or awkward flats where a robust, easily repairable finish is the practical choice.
- Trims, upstands and outlets
- Edge trims, correctly formed upstands and adequate outlets — where nearly all flat roof failures actually begin.
- Falls and firrings
- Firring pieces set the fall so water leaves the roof rather than sitting on it.
- GRP fibreglass
- Laid in situ over a ply deck for balconies and anything walked on, finished with a hard topcoat.

Practical answers before you book
- Can you overlay the existing felt?
- Only if the deck below is dry and sound, and we'll lift a section to check. Overlaying a soft deck buys a year or two and costs the whole job again.
- Do you insulate at the same time?
- We can build a warm deck with insulation above the structure, which usually makes sense if the roof is coming off anyway and the room below is cold or prone to condensation.
- Is the roof walkable?
- GRP takes foot traffic and suits balconies and terraces. EPDM is fine for maintenance access but isn't intended as a walking surface — if you need a usable deck, say so and we'll specify accordingly.
- Does the coastal weather change what you'd specify?
- Yes. Near the coast we lean towards stainless or non-ferrous fixings, dry-fix ridge and verge systems and heavier flashing details, because salt and wind shorten the life of standard mortar-bedded work.
- Do we need permission from East Suffolk Council?
- Most like-for-like roof work doesn't need consent, but listed buildings and conservation areas can. If your property looks like it falls into that, we'll say so at inspection so it's dealt with before work starts.
