Choosing the right flat roofing in Arundel
Flat roofs are popular across Arundel for extensions, garages and dormers. With our mix of historic buildings and newer homes, choosing the right material matters for longevity, appearance and budget. Below we compare EPDM rubber, GRP fibreglass and felt, so you can decide what suits your property and plans. If you would like tailored advice, the team at Roofing Arundel is here to help.
EPDM rubber roofing
What is EPDM?
EPDM is a synthetic rubber membrane supplied in large sheets. It is bonded to a prepared deck to create a continuous waterproof layer.
Pros
- Long lifespan with good resistance to UV, frost and ponding
- Large sheets mean fewer seams and fewer potential leak points
- Flexible, so it copes well with building movement and temperature changes
- Low maintenance and easy to repair if damaged
- Lightweight, which is kind to older structures
Cons
- Vulnerable to punctures from sharp objects without walkway protection
- Typically a black finish, which some homeowners may not prefer
- Detailing around complex shapes needs an experienced installer
- Not ideal for heavy foot traffic without additional measures
Best for
Extensions, garages and dormers where reliability and value are key. EPDM suits Arundel’s changeable weather as it handles thermal movement well.
GRP fibreglass roofing
What is GRP?
GRP, often called fibreglass, is a liquid resin system reinforced with glass matting. It cures to form a rigid, seamless shell with preformed trims for clean edges.
Pros
- Seamless finish with excellent waterproofing
- Durable and resistant to regular foot traffic when specified correctly
- Neat appearance with colour options and non-slip finishes
- Great for complex details around skylights, parapets and upstands
- Good fire performance when installed to spec
Cons
- Installation is weather sensitive and best done in suitable temperatures
- Usually higher upfront cost than felt
- Requires a skilled installer for a long-lasting result
- Can be less forgiving if the deck moves excessively
Best for
Balconies, terraces and intricate roofs where a crisp look and strong surface are important. Ideal for homeowners who want a premium finish on visible areas.
Felt roofing
What is felt?
Modern felt roofs use bituminous membranes laid in multiple layers. Systems may be torch-on or self-adhesive depending on the project and safety needs.
Pros
- Budget friendly with a long track record
- Versatile for small roofs and simple shapes
- Repairs are straightforward
- Wide choice of capsheet colours and mineral finishes
Cons
- Shorter lifespan than EPDM or GRP
- Relies on seams, so workmanship is critical
- Torch-on methods require safe site conditions
- Can become brittle with age if not maintained
Best for
Sheds, porches and compact extensions where cost control is a priority and access for periodic maintenance is easy.
Cost, lifespan and maintenance at a glance
As a guide, felt typically offers around 10 to 20 years, EPDM 25 years or more, and GRP 20 to 30 years when installed and maintained correctly. Maintenance for all three is simple: keep gutters clear, remove debris, check flashings and inspect after storms. Prompt repairs prevent minor issues becoming bigger problems.
Planning a flat roof in Arundel
Arundel’s riverside setting and proximity to the coast mean roofs must cope with wind, rain and strong sun in summer. Good detailing at edges and penetrations is essential. In conservation areas or on period homes near landmarks like the Castle, appearance may be a factor, so GRP trims or coloured felts can help meet aesthetic aims.

Which should you choose?
- Pick EPDM for reliable performance at sensible cost on straightforward roofs
- Pick GRP for a smart, seamless finish on terraces or complex details
- Pick felt for tight budgets or small outbuildings that are easy to access
