Signs You May Need A Flat Roof Repair
Pooling or Standing Water After Rain
Water that sits on your flat roof indicates improper drainage and puts stress on the membrane.
Blistering, Cracking or Splitting
Visible blisters, cracks, or splits in the membrane are signs the surface is failing.
Leaks or Damp Patches Indoors
Stains on the ceiling below a flat roof are often the first sign of a problem.
Loose or Lifting Edges
Edges and trims that have lifted let wind and water get behind the membrane.
Roof Over 15-20 Years Old
Older felt systems typically reach the end of their life around this age and become more cost-effective to replace.

The true cost of cheap work.
A low quote for a flat roof can be tempting, but poor workmanship isn't just cosmetic; it can lead to serious, expensive problems. We'll beat any genuine quote without cutting corners.
Incorrect Sloping
Without the correct falls, water pools on the roof, stressing the membrane and causing leaks.
Weak Joints
Joints and seams that aren't bonded correctly open up and let water straight in.
Improper Materials
Cheap, thin materials won't stand up to the weather and fail far sooner than they should.
No Ventilation
Skipped ventilation traps condensation, rotting the decking from the inside out.

Things people ask about our flat roofing.

Yes. Flat roof repairs are a big part of what our flat roofers do across Surrey, from garage roofs in Molesey to kitchen extensions in Walton-on-Thames. Most leaks come from a specific weak point, such as a blister or split in the membrane, a failed joint, a lifted edge trim or water pooling where the roof doesn't drain properly.
We locate the source of the leak first, rather than covering the whole roof in sealant and hoping for the best. Depending on what we find, a lasting repair might mean patching a felt roof, re-bonding a seam on an EPDM rubber roof, repairing a GRP fibreglass surface or replacing a damaged section of decking.
Sometimes a repair isn't the best value. If the roof has reached the end of its life, the decking underneath is soft or saturated, or the same roof keeps leaking in new places, a full flat roof replacement will usually cost you less in the long run. We'll show you photos and explain the options honestly during your free inspection.
Every flat roof repair is backed by a My Local Roofer workmanship warranty, and there's never a deposit to pay. As a local roofing company, we'd rather give you an honest answer than sell you work you don't need.
It depends mainly on the material and how well it was installed. A professionally fitted EPDM rubber roof typically lasts around 25 to 30 years, and a well-laid GRP fibreglass roof offers a similar lifespan. Traditional felt flat roofs usually last 10 to 15 years, although modern multi-layer torch-on felt can do better.
Installation quality makes a huge difference. A flat roof laid without the right falls will hold standing water, poorly bonded joints open up, and missing ventilation lets condensation rot the decking from the inside. Many of the failed flat roofs our roofers replace across Surrey had decent materials let down by poor workmanship.
Maintenance helps too. Keeping the roof clear of leaves and moss, making sure outlets drain freely and checking the edges after storms can add years to any flat roofing system. Small problems, like a lifted trim, are cheap to fix early and expensive to ignore.
If your flat roof is getting on in years, our roofers in Surrey can inspect it for free and tell you honestly how much life it has left. When it's time for a replacement, we'll recommend the system that suits your property and budget, backed by our workmanship warranty.
There isn't one best flat roofing material for every home, but EPDM rubber roofing and GRP fibreglass roofing are the two leading modern systems, and both outperform traditional felt on lifespan and maintenance. Which is right for you depends on the size and shape of the roof, how it's used and your budget.
EPDM is a synthetic rubber membrane, usually laid as a single seamless sheet on smaller roofs. It's flexible, copes well with UV and temperature changes, and is quick to install, which makes it a popular choice for garages, extensions and dormers. It's also relatively easy to repair if it's ever damaged.
GRP, or glass reinforced plastic, is laid as a liquid resin with fibreglass matting that cures to a hard, seamless surface. It handles light foot traffic well and copes with awkward shapes and upstands. Felt remains a cost-effective option where budget matters most, and modern torch-on felt is far better than the older systems many homeowners remember.
Our flat roofers will look at your roof, explain the pros and cons of each system in plain English and recommend the one that gives you the best value. Whatever you choose, it's fitted by our own team and backed by a My Local Roofer workmanship warranty.
Yes. We inspect flat roofs for free, with no call-out fee and no obligation to go ahead. Whether it's a leaking garage roof in Hersham or a tired extension roof in Thames Ditton, one of our flat roofers will come out and assess it properly.
A thorough flat roof inspection looks at more than the surface. We check for blisters, splits and cracks, test the joints and edge trims, look for standing water and signs of poor drainage, and where possible check the decking and ventilation underneath. We photograph what we find so you can see it for yourself.
You'll then get a clear written quote explaining whether a repair will do or whether a replacement is the better investment, with the materials, timescale and price set out in plain English. We name the system and products we'll use, so you can compare quotes like for like.
There's never a deposit to pay. If you choose us, you only pay once the work is finished and you're happy with it, which is how we believe a good roofing company in Surrey should operate.
The cost of a flat roof in Surrey depends on the size of the roof, the system you choose and the condition of what's underneath. A small EPDM garage roof is a very different job from a large GRP extension roof with new insulation and decking, so we don't publish fixed prices that wouldn't reflect your property.
The main cost factors are roof area, the flat roofing system (felt, EPDM rubber or GRP fibreglass), whether the old roof needs stripping, the state of the decking, insulation requirements, detailing such as upstands, outlets and edge trims, and access. Upgrading insulation can be required when a flat roof is replaced, and it also helps cut heating bills.
We give every customer a free inspection and a detailed written quote before any work begins, so you know exactly what you're paying for. There's no deposit, and we'll beat any genuine like-for-like quote from other flat roofers without cutting corners.
The cheapest flat roof is rarely the best value. A properly installed EPDM or GRP flat roof can last decades, while a poorly laid one can fail within a few years. Our flat roofing is backed by a My Local Roofer workmanship warranty, so you're covered either way.
Yes. Extensions, garages, dormers, porches and outbuildings make up most of the flat roofing we install across Surrey. Each one needs a slightly different approach, depending on how the space below is used and how the roof meets the rest of the house.
For a heated extension or dormer, we usually recommend a warm roof build-up, with insulation laid above the deck and the waterproof membrane on top. This keeps the structure warm, reduces the risk of condensation and helps the room meet current insulation standards. For an unheated garage or shed, a simpler cold roof can be perfectly adequate.
Getting the details right is what stops a flat roof leaking. That means correct falls so water runs off rather than pooling, properly sealed upstands where the roof meets walls and windows, neat edge trims, and outlets that carry rainwater away. Our flat roofers take care over every one of those details.
We'll recommend the right system for your project, usually EPDM rubber or GRP fibreglass, and give you a clear written quote. All of our flat roofing work is carried out by our own team and backed by a My Local Roofer workmanship warranty.
