Roofing materials flat (Real Talk Guide)

So, your flat roof’s looking tired — maybe the felt’s bubbling, or that little puddle in the corner just won’t go away.

Now you’re wondering what to replace it with.

Here’s the truth: not all flat roof materials are built equal.

Some will hold strong through twenty British winters.

Others… not so much.

Let’s break it down without the technical jargon.

1.EPDM Rubber- The Smart, Modern Choice

If you want something tough, clean, and low-maintenance, this is it.

EPDM (that black rubber-looking stuff) is what most modern flat roofs use.

It’s a single sheet, no joins, no leaks — basically the superhero of roofing membranes.

✅ Lasts 20–25 years

✅ Costs around £70 per m²

✅ Weatherproof and eco-friendly

✅ Ideal for extensions, dormers, and garages

It’s flexible too — literally. It expands and contracts with the weather, which means fewer cracks over time.

2.Fibreglass (GRP) — The Premium Look

Fibreglass, also called GRP roofing, gives a sleek, solid finish that looks amazing.

If you want your roof to double as a neat outdoor surface or just prefer a modern aesthetic — this one’s worth a look.

✅ Lasts up to 30 years

✅ Costs £80–£100 per m²

✅ Durable and weatherproof

⚠️ Needs proper installation — not a DIY job

Think of GRP as the “designer option” of flat roofs.

3. Felt Roofing — The Budget Option

We all know felt roofs — the old-school method.

Still used, still affordable, still fine for smaller buildings like sheds or garages.

✅ Cheap upfront (around £40–£50 per m²)

⚠️ Needs more maintenance

⚠️ Shorter lifespan — 10–15 years tops

If you just need a quick fix or a short-term solution, felt works.

But if you’re thinking long-term, EPDM or fibreglass will save you money over time

Quick Comparison

Material	Cost per 𝑚2	Lifespan	Maintenance	Verdict
EPDM Rubber	€70	20-25 Years	Very Low	Best Value
Fibreglass (GRP)	€80-€100	25-30 Years	Low	Sleek & Durable
Felt	€40-€50	10-15 Years	High	Cheapest Option

So, What's Right for YOU?

If you want value and durability, go EPDM.

If you want style and strength, go fibreglass.

If you just want cheap and quick, go felt.

No one-size-fits-all answer — it depends on your budget, how long you’ll stay in the house, and what you expect from the roof.
