How Much Does EPDM, GRP or Felt? Choosing the Best Flat Roofing System for Your Caerphilly Property Cost?
The cost of a new flat roof in Caerphilly will depend on the material chosen, the size of the roof area, ease of access, and any additional preparation work required. Here is a general guide to help you budget:
- Felt flat roof (small garage or extension, up to 20m²): Typically £800 – £1,500, making it the most affordable entry-level option for straightforward projects.
- EPDM rubber flat roof (medium extension, 20–40m²): Usually between £1,500 – £3,000, offering excellent value for money given its 20–25 year expected lifespan and low maintenance requirements.
- GRP fibreglass flat roof (medium to large, 20–50m²): Generally £1,800 – £4,000+, reflecting the premium durability and near-zero maintenance demands of fibreglass over its lifetime.
- Flat roof repair (patch or section): Minor repairs typically start from £150 – £500 depending on the extent of damage and the material already in place.
- Full flat roof replacement (large commercial or residential, 50m²+): Costs can range from £4,000 – £10,000+ depending on the system chosen, access requirements, and any structural work needed beneath the membrane.

Frequently Asked Questions — EPDM, GRP or Felt? Choosing the Best Flat Roofing System for Your Caerphilly Property
Which flat roofing system lasts the longest — EPDM, GRP, or felt?
GRP fibreglass generally offers the longest lifespan, often exceeding 25–30 years with minimal maintenance. EPDM rubber closely follows at 20–25 years. Traditional felt is the shortest-lived option, typically lasting 10–15 years, though modern torch-on felt systems can perform better than older alternatives.
Is EPDM rubber roofing suitable for the wet Welsh climate in Caerphilly?
Absolutely. EPDM is highly resistant to UV radiation, extreme temperatures, and heavy rainfall — making it an excellent choice for properties in Caerphilly and across South Wales. Its flexibility means it handles thermal expansion and contraction well, reducing the risk of cracking or splitting over time.
Can I walk on a GRP fibreglass flat roof?
Yes, a correctly installed GRP flat roof can withstand foot traffic, which is why it is popular for roof terraces and walkways as well as standard flat roofs. However, you should avoid dragging sharp objects or heavy equipment across the surface to prevent accidental damage to the membrane.
How do I know if my existing flat roof needs replacing rather than repairing?
Key signs include persistent leaks after repairs, widespread blistering or cracking, sagging sections, or a felt roof that is more than 15 years old. Dragon Shield Roofing offers free surveys to assess your roof honestly and advise whether a repair or full replacement represents better long-term value.
Do I need planning permission to replace a flat roof in Caerphilly?
In most cases, like-for-like flat roof replacements are covered under permitted development rights and do not require planning permission. However, if you are altering the roof height, adding a roof terrace, or the property is listed or in a conservation area, you should check with Caerphilly County Borough Council beforehand.
How long does it take to install a new flat roof?
Most standard domestic flat roof installations — such as a garage or single-storey extension — are completed within one to three days. Larger or more complex projects may take longer. Dragon Shield Roofing will give you a realistic timeframe as part of your free quotation so you can plan accordingly.
Does Dragon Shield Roofing offer a guarantee on flat roof installations?
Yes. We stand behind the quality of our workmanship and offer guarantees on our flat roofing installations. The specific terms will depend on the system installed — GRP and EPDM roofs typically carry longer guarantees than felt. Full details will be provided in writing before any
