Garage Roof Replacement: Felt, EPDM or GRP?

When it comes to replacing a garage roof, the biggest question most homeowners face is simple: which roofing material should I choose? With several options available – each with its own strengths and price point – it’s important to understand the differences before committing to a long-term solution.

In this guide, we’ll break down the three most popular garage roofing materials used across the UK: Felt, EPDM and GRP. Whether your roof is leaking, sagging, or simply past its best, this quick comparison will help you choose the right replacement for your home and budget.

Felt Roofing – The Traditional, Budget-Friendly Choice

Best for: Cost-effective replacements, landlords, older garages, short-term fixes
Typical lifespan: 10–15 years

Felt is the most traditional garage roofing material and is usually the cheapest to install. Modern felt roofs are far better than the old versions you may remember – heat-applied bitumen layers and mineral-finished surfaces help improve durability and weather resistance.

Pros of Felt Roofing

• Affordable – usually the lowest cost option.
• Fast installation – minimal disruption and quick turnaround.
• Flexible – works well on uneven or older garage structures.
• Easier repairs – small sections can be patched if needed.

Cons of Felt Roofing

• Shorter lifespan than EPDM or GRP.
• Vulnerable to wear from heat and UV over long periods.
• Not as modern-looking as rubber or fibreglass alternatives.

If budget is your key priority, felt is a solid and reliable option.

EPDM Rubber Roofing – Long-Lasting and Low Maintenance

Best for: Modern homes, long-term value, single-piece waterproofing
Typical lifespan: 20–30+ years

EPDM (Ethylene Propylene Diene Monomer) is a synthetic rubber membrane known for its durability and weather resistance. It’s incredibly popular for garages and flat roofs because it’s installed as one large sheet, meaning no joins and fewer potential leak points.

Pros of EPDM Roofing

• Very long lifespan – often decades with minimal issues.
• Excellent waterproofing thanks to its seamless design.
• Low maintenance – doesn’t crack, blister or split easily.
• UV and weather resistant – ideal for UK conditions.
• Environmentally friendly – recyclable and energy-efficient.

Cons of EPDM Roofing

• Higher initial cost than felt.
• Can puncture if walked on with sharp objects.
• Appearance is plain black, which some homeowners may not prefer.

If you want a reliable, long-term roof that requires almost no attention, EPDM is hard to beat.

GRP Fibreglass Roofing – The Premium, Toughest Option

Best for: A flawless finish, maximum durability, modern garages and workshops
Typical lifespan: 25–40+ years

GRP (Glass Reinforced Plastic), often called fibreglass roofing, is one of the toughest flat roofing systems available. Installed using layers of resin and fibreglass matting, it hardens into a single rigid shell with a smooth, seamless finish.

Pros of GRP Roofing

• Extremely durable – impact-resistant and built to last decades.
• Completely seamless – excellent waterproofing.
• Attractive finish – available in various colours and trims.
• Low maintenance – very little upkeep needed.
• Fire-resistant – ideal for garages or workshops.

Cons of GRP Roofing

• Usually the most expensive of the three.
• Installation must be perfect – only recommended from experienced installers.
• Can become slippery when wet unless a non-slip finish is added.

If you want the strongest and smartest-looking garage roof, GRP is the premium choice.

So… Which Garage Roof Material Should You Choose?

Here’s a quick comparison:

Our Recommendation

• Choose Felt if you want the cheapest, no-frills replacement.
• Choose EPDM if you want a long-lasting, low-maintenance, modern roof.
• Choose GRP if you want the strongest, most durable, premium finish that looks fantastic.

Every property is different, so the right material depends on your budget, the condition of your garage structure, and how long you plan to stay in your home.
