Do You Have a Leaking Flat Roof?
A leaking flat roof needs attention quickly. Left alone, water finds its way into the roof deck, then into the structure below. What starts as a damp patch on a ceiling can become rotten timbers and damaged plasterwork within a season.
The most common signs of a failing flat roof are water stains on the ceiling below, bubbling or blistering on the roof surface, pooling water that doesn’t drain away and visible cracks or splits in the membrane. If you notice any of these, call us and we’ll come out to assess it. Catching problems early keeps repair costs low. You can also read more about our general roof repair service if you think the issue is wider than the flat roof alone.
Flat Roof Repair in Stoke-on-Trent
Not every flat roof needs replacing. Many can be repaired at a fraction of the cost of a full installation. We carry out repairs on all types of flat roof systems, including felt, EPDM rubber and GRP fibreglass.
When we visit, we inspect the full roof surface, not just the obvious problem area. We check for underlying damage to the deck boards and insulation before recommending a course of action. We’ll tell you honestly whether a repair will hold or whether replacement makes more sense at this stage. We never push for a full replacement if a repair is the right answer.

New Flat Roof Installation in Stoke-on-Trent
If your flat roof is beyond repair, or you’re building a new extension and need a flat roof specified from scratch, we can help. We install three main systems.
GRP fibreglass roofing is the most popular choice for domestic properties in Stoke-on-Trent. It’s hard-wearing, fully seamless and carries a 25-year product guarantee from most manufacturers. It suits extensions, garages and bay windows well.
EPDM rubber roofing is a single-ply membrane system. It’s flexible, lightweight and excellent on larger flat roof areas. EPDM handles temperature changes well, which makes it a reliable option through Staffordshire winters.
Felt roofing is a more traditional system. It costs less upfront but has a shorter lifespan than GRP or EPDM. We fit felt roofs where budget is the priority, using high-performance torched-on felt rather than the older bonded systems.
We’ll explain the pros and cons of each option when we visit and recommend what suits your property and budget best. If you’re planning a full extension at the same time, take a look at our new roof installation service too.
What the Installation Process Involves
We strip the old roof covering back to the deck. We inspect and replace any rotten or damaged deck boards at this stage. New insulation goes down where needed, then the chosen system is installed on top.
GRP roofs are laminated in place and cure to form a solid, seamless surface. EPDM membranes are bonded down and sealed at all edges and penetrations. We fit new drip trim and edge details to all perimeters and make sure all outlets and downpipes run clear before we leave.
We clear all waste from site on the same day. Most single-garage or small-extension roofs are finished in a day. Larger jobs take two days. We always give you a realistic timeframe before starting.

Flat Roofs on Garages and Extensions Across Stoke-on-Trent
Flat roofs are common across the Potteries. Older terraced and semi-detached properties often have flat-roofed rear extensions, bay window roofs and garage roofs that are decades old and overdue for replacement. We work across Stoke-on-Trent, Newcastle-under-Lyme, Kidsgrove, Biddulph, Leek and the surrounding villages.
While we’re on site, we’re happy to check the condition of your fascias and soffits, guttering and roof soffits at the same time. Combining work in a single visit saves you time and keeps costs down.

How much does a new flat roof cost in Stoke-on-Trent?
The cost depends on the size of the roof, the system chosen and the condition of the existing deck. A standard single-garage flat roof in GRP fibreglass will cost less than a larger extension roof. We provide free written quotes for all flat roof work across Stoke-on-Trent — call 07351 639478 to arrange a visit.
-
Which flat roof system is best — GRP, EPDM or felt?
GRP fibreglass is the most popular choice for domestic properties. It’s seamless, hard-wearing and carries a long guarantee. EPDM rubber suits larger roofs well. Felt is a lower-cost option with a shorter lifespan. We’ll recommend the right system for your property and budget when we visit.
-
How long does a GRP fibreglass flat roof last?
A properly installed GRP fibreglass flat roof should last 25 years or more. Most manufacturers offer a 25-year product guarantee. EPDM rubber roofs have a similar lifespan. Traditional felt roofs typically last 10 to 15 years depending on the specification and how well they are maintained.
-
Can you repair a flat roof rather than replace it?
Yes, in many cases. If the roof deck is sound and the damage is localised, a repair is often the right option. We assess the full roof before recommending anything. If a repair will hold for several more years, we’ll say so. If the roof is at the end of its life, we’ll tell you that too.
-
How long does flat roof installation take?
Most single-garage or small-extension flat roofs take one day to complete. Larger roofs or those needing deck repairs may take two days. We give you a clear timeframe before we start so you know exactly what to expect.
-
Do flat roofs need planning permission?
Replacing an existing flat roof like-for-like does not need planning permission. If you’re adding a new flat-roofed extension, permitted development rules usually apply for most domestic properties. If you’re unsure, Stoke-on-Trent City Council’s planning portal is the best place to check for your specific property.
