It's the Install, Not the Roof
Flat roofs get a bad reputation — usually because they were installed badly. A poorly fitted felt roof from the 1980s will leak within a few years. A properly installed EPDM or GRP system, done right, will last 30 to 50 years with minimal maintenance.
Pitch Perfect Norfolk install and repair flat roofs across Norfolk on extensions, garages, outbuildings, dormer cheeks, and single-storey additions. We work with EPDM rubber, GRP fibreglass, and felt flat roofing systems — and we'll give you an honest recommendation on which one suits your project, your budget, and how long you want it to last.

Flat Roofing Systems We Install Across Norfolk
We install new roofs on all residential property types across Norfolk — from terraced houses and semis to detached properties, bungalows, extensions, garages, and outbuildings.
What We Install
EPDM Rubber Roofing
EPDM (ethylene propylene diene monomer) is the most popular flat roofing system we install — and for good reason. It's a single-ply rubber membrane that goes on in one piece, which means no seams and no weak points where water can get in.
Why homeowners choose EPDM:
- Lifespan of 40–50 years with proper installation
- Single-piece membrane — no joins, no seams, no weak points
- Fully waterproof from day one
- Handles Norfolk's temperature extremes well — flexible in cold, stable in heat
- Low maintenance once installed
- Lighter than GRP — suitable for most roof structures without additional support
- Cost-effective over its lifespan compared to felt systems that need replacing every 10–15 years
Best suited to: Extensions, garage roofs, outbuildings, and larger flat roof areas where a seamless finish is important.
GRP Fibreglass Roofing
GRP (glass reinforced plastic) flat roofing is a rigid, seamless system that bonds directly to the roof deck. It looks similar to EPDM once finished but has a harder surface and a slightly different finish — some homeowners prefer it aesthetically, particularly where the roof is visible from above.
Why homeowners choose GRP:
- Extremely durable and rigid surface — handles foot traffic better than EPDM
- Seamless finish — no joins or seams
- Fire resistant
- Can be finished in a range of colours
- Lifespan of 25–40 years with proper installation
- Suitable for roof terraces and walkable surfaces
Best suited to: Roof terraces, flat roofs where foot access is required, and properties where a harder-wearing surface is preferred.
One thing to be aware of: GRP is more sensitive to movement in the roof deck than EPDM. On older properties with more flex in the structure, EPDM is often the safer choice. We'll flag this at the survey stage.
Felt Flat Roofing
Traditional built-up felt roofing has been used for decades and remains a cost-effective option for straightforward flat roof projects. Modern torch-on felt systems are significantly better than the old mineral felt that was common in the 1970s and 80s — but felt still has a shorter lifespan than EPDM or GRP.
Why homeowners choose felt:
- Lower upfront cost than EPDM or GRP
- Widely understood and straightforward to repair
- Suitable for most standard flat roof applications
- Modern torch-on systems are more durable than older felt systems
Be aware: Felt flat roofs typically last 10–20 years before they need replacing. Over the full lifespan of a property, EPDM or GRP will almost always work out cheaper. We'll give you the full picture at quote stage so you can make an informed decision.
Best suited to: Budget-conscious projects, garages, outbuildings, or situations where a lower upfront cost is the priority.
Flat Roof Repairs Across Norfolk
Whether it's a garage roof, a dormer, an extension, or an ageing flat roof that's started to blister, crack, or hold water, a flat roof needs the right system and proper installation — not a quick patch that fails again within a year.
A flat roof repair means identifying the actual cause first — often a split membrane, a failed joint, or standing water sitting where the falls aren't right — then fixing it properly rather than just sealing over the surface. Depending on what we find, that might mean patching the affected area, replacing a section of the membrane, or in some cases a full recover using EPDM, GRP, or felt.
We handle everything from the initial inspection through to the finished repair. No project management headaches, no coordinating multiple trades. One team, start to finish.

Common flat roof problems we fix:
Choosing the right material is one of the most important decisions in a new roof project. Here's a straightforward guide to the main options we work with:
Blistering and bubbling
Usually caused by moisture trapped beneath the membrane during installation or by age. Can lead to cracking and water ingress if left. We assess whether a repair or full replacement is the right call.
Ponding water
Flat roofs should drain within 48 hours of rainfall. If water is sitting on your roof for longer, there's a drainage problem that needs addressing. Left untreated, standing water accelerates membrane deterioration significantly.
Cracking and splitting
Particularly common on older felt systems. Once a membrane starts cracking, water will find a way in. We'll assess the extent of the damage and advise on repair vs replacement.
Leaks and water ingress
The most common reason people call us. We'll find the actual source of the leak — which isn't always where the water is coming through inside — and fix it properly.
Failing upstands and edges
The edges and upstands where the flat roof meets walls and parapets are the most vulnerable points on any flat roof system. We repair and replace edge trims, upstands, and drip edges on all system types.
We'll talk through the options at the survey stage and give you a clear recommendation based on your roof size, how it's used, your budget, and how long you want it to last. There's no one-size-fits-all answer — EPDM, GRP, and felt each suit different situations, and the right choice depends on your specific property.
EPDM, GRP, or Felt
Which Should You Choose?
Here's a quick comparison to help you understand the options before we come out.
In most cases we recommend EPDM for standard domestic flat roofs — it's the best balance of cost, lifespan, and performance. If you need a walkable surface or have a specific aesthetic requirement, GRP may be the better choice. We'll give you a clear recommendation after we've seen the job.

Common Flat Roofing Questions, Answered
A standard garage or extension flat roof typically takes one to two days to install. Larger or more complex roofs may take longer. We'll confirm the timescale at the quote stage.
Yes — all our flat roof installations come with a five-year warranty as standard.
Replacing a flat roof with the same system usually doesn't require planning permission. Changing the roof type or height might. If you're in a conservation area or have a listed building, different rules apply. We'll flag anything relevant at the survey stage.
Signs your flat roof may need replacing rather than repairing: widespread cracking or blistering across the membrane, persistent leaks in multiple areas, pooling water that doesn't drain within 48 hours, visible sagging, or a felt system that's over 15 years old. We'll assess it properly when we come out.
Yes — if the existing system is repairable, we'll tell you that and fix it. A repair is always cheaper than a replacement. We'll give you an honest assessment at the survey stage on whether repair or replacement is the right call for your roof.
A new flat roof on a typical single-storey extension or garage in Norfolk costs between £1,500 and £5,000 depending on size and the system chosen. EPDM and GRP cost more upfront than felt but last significantly longer. We'll give you a fixed written quote after a free survey.
For most domestic garages and extensions, we recommend EPDM rubber. It's the best balance of cost, lifespan, and performance — and the single-piece membrane means no seams to fail. For walkable surfaces or roof terraces, GRP is usually the better choice.
It depends on the system. EPDM rubber roofs last 40–50 years with proper installation. GRP fibreglass roofs last 25–40 years. Traditional felt roofs last 10–20 years. We'll recommend the right system for your project at the survey stage.
