Flat roofing in West London: which system, and when to repair or replace
For most home extensions in West London, an EPDM rubber membrane over a warm-deck insulated build is the most durable, lowest-maintenance flat roof. GRP fibreglass suits roofs you walk on, such as balconies and terraces. Torch-on felt remains a sound budget choice for garages and outbuildings. We survey first, then recommend the system that fits your roof and budget.
Which flat roof system is right for your property?
The right system depends on how you use the roof, its shape and your budget. So here is how the three main options compare:
| System | Typical lifespan* | Best for | Things to know |
|---|---|---|---|
| EPDM rubber | 30+ years | Rear extensions, dormers, garage roofs | Usually laid as one seamless sheet on domestic roofs. It also stays flexible in frost and sun. However, it is not meant for regular foot traffic. |
| GRP fibreglass | 25+ years | Balconies, terraces, roofs with lots of detailing | Hard, walkable finish. However, we can only lay it in dry weather, and it cures best above about 5°C. |
| Torch-on felt (3-layer) | 15–25 years | Garages, sheds, outbuildings, tight budgets | Lowest upfront cost. Also, a proper three-layer system with a mineral cap sheet lasts far longer than cheap single-layer felt. |
*Industry-typical ranges for a correctly installed system. Actual life depends on the product, installation quality, drainage and maintenance.
Signs your flat roof needs repair or replacement
- Ponding water that is still sitting on the roof 48 hours after rain.
- Blisters, splits or cracks in felt, or seams lifting on a rubber membrane.
- Damp patches or mould on the ceiling under the flat roof.
- A soft or spongy feel underfoot, because the timber deck beneath has usually got wet.
- Lifted edge trims or failed flashing where the roof meets a wall.
Repair or replace?
If the damage is local and the deck underneath is dry and solid, a repair is usually the right call. If the deck is rotten, the covering has failed in several places, or the roof is near the end of its life, replacing it is normally better value than paying for repeated repairs. Either way, we will tell you which applies after the survey. Also, for leaks and one-off faults, see our roof repair service.
Warm roofs, insulation and Building Regulations
Under the Building Regulations in England, replacing 50% or more of a flat roof counts as renovating a "thermal element". This applies even if you like-for-like replace the covering, and it normally means bringing the insulation up to current standards. For this reason, we usually build a warm deck: rigid insulation boards go on top of the timber deck, under the waterproof layer. As a result, the structure stays warm and condensation is far less likely. For more detail, see the LABC guidance on roofs and Building Regulations.
Planning permission: replacing an existing flat roof like-for-like does not normally need planning permission. However, listed buildings, conservation areas and changes to the roof's height or shape can be different. Either way, we will flag anything that needs checking at the survey.
What affects the cost of a flat roof?
- The size of the roof in square metres, and which system you choose.
- Whether the old layers can stay or need stripping, and whether any of the deck needs replacing.
- Insulation upgrades, if needed to meet Building Regulations.
- Access: a ground-floor extension is simpler than a second-floor dormer that needs scaffolding.
- Details such as rooflights, upstands, outlets, edge trims and lead or wall flashings.
For this reason, we price every flat roof after a free survey and put the full cost in writing.
How long does a flat roof replacement take?
We usually strip and re-roof a typical single-storey rear extension in one to three days, depending on the system and the weather. EPDM is the quickest to lay, while GRP needs a dry spell to cure. Larger or more complex roofs take longer, so we will give you a timeline with your quote.

Flat roofing in West London: FAQs
How long does an EPDM rubber flat roof last?
A correctly installed EPDM roof typically lasts 30 years or more. However, its lifespan depends on the quality of the membrane, how well we detail the edges and outlets, and whether water drains off the roof properly.
Is GRP or EPDM better for a flat roof?
In short, neither is better for every roof. EPDM is usually the best choice for extensions and dormers that people rarely walk on. GRP is better for balconies, terraces and roofs with complex shapes because it gives a hard, walkable surface.
Do I need planning permission to replace a flat roof?
Like-for-like replacement of a flat roof does not normally need planning permission. Listed buildings, conservation areas and changes to the height or shape of the roof may need approval. Replacing 50% or more of the roof does bring Building Regulations into play, including insulation.
Can you fix a leaking flat roof in the rain?
We can make a leaking flat roof temporarily watertight in wet weather, and our emergency line runs 24/7. Permanent repairs to felt and GRP need dry conditions, so we come back to complete them when the weather allows.
How much does a new flat roof cost?
The price depends on the roof size, the system you choose, the condition of the deck, insulation requirements and access. That is why we give a free survey and a written, itemised quote so you know the full cost before any work starts.
