EPDM vs Felt vs GRP – What’s the Best Flat Roofing Choice for Bishopsworth?

If you’re planning a new flat roof in Bishopsworth, choosing the right material is key to long-term performance and peace of mind. At Brunel Roofing Bristol, we specialise in EPDM rubber roofing in Bishopsworth, and many of our customers ask how it compares to felt and GRP.

1. EPDM Rubber Roofing

EPDM (Ethylene Propylene Diene Monomer) is a synthetic rubber membrane designed for durability and flexibility.

• Pros: Long lifespan (30–50 years), highly weather resistant, low maintenance
• Best for: Residential flat roofs, garages, dormers, and commercial buildings

2. Felt Roofing

Traditional felt is still widely used, especially for smaller structures.

• Pros: Low upfront cost, quick installation
• Cons: Shorter lifespan (10–15 years), prone to cracking and blistering over time

3. GRP Roofing (Fibreglass)

Glass Reinforced Plastic (GRP) is a modern, hard-shell roofing option.

• Pros: Very strong and visually appealing
• Cons: Requires dry weather to install, can be brittle if not applied correctly

Why EPDM Is the Better Long-Term Option

While felt and GRP have their uses, EPDM stands out for its weather resistance, cost-effectiveness, and long-term durability. It’s ideal for Bishopsworth homeowners who want a worry-free roof that won’t need constant attention.
