EPDM vs. GRP
EPDM vs. GRP: Which Flat Roof System is Right for You?
When choosing a new flat roof, homeowners often compare EPDM rubber and GRP fibreglass. Both systems offer excellent weatherproofing and long life, but they differ in cost, appearance, and installation method. Here’s how to decide which is right for your property.
What is the main difference between EPDM and GRP?
The main difference is that EPDM is a flexible rubber membrane installed in large sheets, while GRP (fibreglass) is a rigid, seamless coating created by layering resin and glass fibre matting.

Although both EPDM and GRP give long-lasting, watertight protection, they differ in how they’re installed and how they perform over time.
EPDM (rubber) is laid in large sheets and glued to the roof deck. With few joins, it’s quick to fit and very flexible, expanding and contracting with temperature changes. It’s ideal for larger or simple roofs where speed, cost and reliability matter.
GRP (fibreglass) is built up on site using layers of resin and glass fibre that harden into a rigid, seamless shell. It delivers a smooth, durable finish that looks smart and resists impact and weathering. Installation takes longer and must be done in dry conditions, but the result is a premium, maintenance-free surface.
In short, EPDM suits larger straightforward roofs, while GRP is best for smaller or detailed roofs needing a high-end finish.
GRP (Fibreglass) Roofing: Pros and Cons
The Advantages (Pros)
Seamless and Watertight: GRP is a liquid-applied system that cures to create a single, monolithic, seamless surface, eliminating the leak risk associated with joints and seams.
Exceptional Durability and Lifespan: Offers a high strength-to-weight ratio, is resistant to weathering, UV, and corrosion, often providing a lifespan of 30+ years when installed correctly.
More Pros
Superior Aesthetics: It provides a hard, clean, modern finish that can be coloured and is often favoured for visible roofs, balconies, and terraces.
Walkable Surface: Due to its rigid, hard composite nature, GRP is highly resistant to punctures and can withstand light foot traffic (for maintenance access) better than other flexible systems.
Easy to Repair: While durable, any isolated damage is localised and easy to patch with a GRP repair kit, without needing to replace the entire membrane.
The Disadvantages (Cons)
Higher Initial Cost: The specialised materials and the skilled nature of the application mean GRP generally has a higher upfront installation cost than EPDM.
Requires Expertise: Proper installation is highly dependent on the contractor’s skill to ensure the correct resin ratios and seamless finish; poor installation can lead to cracking.
More Cons
- Weather Dependent Installation: GRP is a cold-applied liquid that must be installed in completely dry conditions above a certain temperature, which can delay projects in cooler or wet UK weather.
Thermal Rigidity: The finished product is rigid and can be prone to thermal cracking over many years due to extreme temperature fluctuations (expansion and contraction) if not installed correctly.
EPDM Rubber Roofing: Pros and Cons
The Advantages (Pros)
Cost-Effective and Quick Installation: EPDM is a synthetic rubber membrane that is typically faster to install than liquid systems and often has a lower material cost, making it highly cost-effective for larger flat roofs.
Highly Flexible and Durable: The rubber material is extremely elastic and flexible, allowing it to easily handle the building’s movement and extreme temperature fluctuations without cracking, shrinking, or becoming brittle.
More Pros
Low Maintenance: EPDM requires very little ongoing care and has an excellent resistance to weathering, UV light, and thermal shock.
Easy to Repair: Repairs are straightforward; small punctures or tears can be easily patched with dedicated EPDM tape or liquid sealant, often a simple DIY fix for minor issues.
Eco-Friendly Option: EPDM is a sustainable and recyclable material with a long service life, appealing to environmentally conscious customers.
The Disadvantages (Cons)
Seams and Joints: EPDM is installed in large sheets, and larger roofs require seams where the sheets are joined. These seams are the most common point of failure if not prepared and sealed perfectly.
Aesthetic: The standard EPDM membrane has a dark, rubberised, industrial look that is often less appealing than GRP, particularly on visible roof areas or balconies.
More Cons
Not a Walkable Surface: While durable, EPDM is a flexible membrane and is susceptible to damage from sharp objects or frequent heavy foot traffic.
Requires Adhesion: The system relies on full adhesion to the substrate; poor preparation or cold spots can lead to bubbling or delamination over time.

FAQ
Ask us anything about flat roofs
What type of flat roof is best for my property?
EPDM rubber suits most homes, while fibreglass (GRP) offers a tougher, seamless finish for high-use areas.
The right flat roof depends on your property type, location, and budget. EPDM rubber is flexible and ideal for domestic roofs, while fibreglass (GRP) offers a seamless, rigid surface suited to high-traffic areas. We assess your roof during a free survey and recommend the best long-term option.
Can a flat roof be completely waterproof?
Yes — modern flat roof systems are fully watertight when installed correctly.
Unlike old felt roofs, today’s EPDM and GRP membranes are designed to resist standing water, frost, and UV damage. Our installations use sealed edges, welded joints, and professional drainage detailing to ensure no water can penetrate. With correct installation and maintenance, a flat roof remains 100% waterproof for decades.
Do flat roofs need planning permission?
Usually not — most flat roof replacements don’t require planning consent.
If you’re simply replacing or upgrading your existing flat roof, it’s classed as maintenance rather than development. However, if your project involves changing the building height, converting a garage, or adding a balcony, you might need permission. We’ll always advise during your quotation if any local approvals or building regulations apply.
Can you install skylights or lanterns in a flat roof?
Yes — flat roofs are perfect for skylights, roof lanterns, and sun tunnels.
These features add natural light and visual appeal, especially on extensions or kitchen conversions. We install rooflights with professional flashing and insulation details to maintain full waterproofing and prevent heat loss. Whether part of a new roof or an upgrade, skylights can completely transform a flat-roofed space.
How can I tell if my flat roof needs replacing?
Visible cracks, ponding water, or internal damp patches are clear warning signs.
As flat roofs age, weather exposure can lead to splitting, bubbling, and small leaks that worsen over time. If you notice ceiling stains or persistent pooling, it’s worth booking an inspection. Our team will check the condition and advise whether a simple repair, overlay, or full replacement offers the best long-term value.
Do you repair older felt flat roofs?
Yes — we can overlay or upgrade felt roofs using modern EPDM or GRP materials.
If your existing felt roof is leaking but the structure underneath is still sound, we can apply a new surface layer to seal and protect it. This approach avoids a full rebuild, reducing cost and disruption while providing far greater durability and weather resistance than traditional felt.
