Roofing in London: flat and pitched roofs
GONT LTD is a London building company that builds, replaces and repairs flat roofs in GRP fibreglass, EPDM or felt, and pitched roofs in slate, clay or concrete tiles, on houses and extensions.
We start with the condition of the roof, its structure and the way water leaves it.
For rooflights and glass roofs, see No1 London, which shares our showroom in Fulham.
Scope
What’s included.
- New flat roofs and replacements in GRP, EPDM or felt
- Pitched roofs in slate, clay or concrete tiles
- Insulation and drainage
- Repairs to flat and pitched roofs
Flat or pitched
Two kinds of roof.
Flat roofs: GRP, EPDM and felt
GRP fibreglass sets into one continuous surface, good for awkward shapes and terraces. EPDM is a rubber membrane with few joints. Torch-on felt is a layered bitumen system.
Pitched roofs: slate and tiles
A timber structure with a breathable membrane, battens and natural slate, clay or concrete tiles. Work ranges from slipped tiles and flashing to re-covering the whole roof, with gutters, fascias and soffits.
Planning your project

- The state of the deck or timbers underneath
- Access and scaffolding

Rules in the UK
Permissions and regulations.
The Planning Portal says re-roofing needs building regulations approval in most situations, and a covering that adds 15 per cent or more to the roof's weight also needs its structure checked. A roof is a thermal element, so re-covering it normally means improving its insulation; see the Planning Portal guide to re-roofing. A roof on a new extension or loft conversion is planned with that work.
General guidance only, based on gov.uk and the Planning Portal. Your council or building control has the final say.
Things to watch
- Bats are protected: if there may be bats in the roof, a survey can be needed.

FAQ
Roofing: your questions.
Which is best for a flat roof: GRP, EPDM or felt?
There is no single best choice: GRP suits awkward shapes and terraces, EPDM simple roofs with few joints, felt a traditional layered finish.
Can a flat roof be repaired, or does it need replacing?
Often, yes: a small fault can be repaired, but a roof failing in several places is usually better replaced.
Does re-roofing need building regulations approval?
In most situations, yes, according to the Planning Portal, and re-covering a roof normally means improving its insulation.
Do I need planning permission to re-roof my house?
Usually not, if the new covering looks similar to the old one. Listed buildings and conservation areas have stricter rules.
Do you give a warranty?
Yes. GONT LTD offers a 6-month warranty on its construction services. If an issue appears in that time, we come back and put it right.
