Flat roofs are a popular choice across South Wales, especially for extensions, garages, porches and commercial buildings. If you need a new flat roof or repairs to an existing one, our team can help. We install and maintain a wide range of modern flat roofing systems designed for durability, weather protection and long-term performance.
We work across Merthyr Tydfil, Caerphilly, Rhondda, Cardiff and the wider South Wales region, providing reliable, high-quality flat roof services for homeowners and businesses.
Flat Roof Installation and Replacement
A well-installed flat roof can last decades with the right materials and workmanship. Whether you’re building an extension or replacing an ageing roof, we can recommend a system that suits your property and budget.
We install several flat roofing options, each with different strengths.
Felt Flat Roofs
Torch-on felt is a reliable and cost-effective option. Modern felt systems have improved significantly and now offer strong waterproofing, good flexibility and a long service life.
GRP Fibreglass Flat Roofs
Fibreglass (GRP) is a seamless, highly durable system ideal for flat roofs that need a tough, hard-wearing finish. It’s resistant to cracking, UV damage and standing water, making it a popular choice for homes and commercial buildings across South Wales.
EPDM Rubber Roofs
EPDM is a flexible single-ply membrane that’s easy to maintain and designed to last for decades. It’s perfect for garages, extensions and dormers. You can read more about this on our dedicated Rubber Roofing page.
Warm Roof Systems
Warm flat roofs add insulation above the joists, helping improve your property’s energy efficiency. They’re often recommended for extensions and newer builds.
Flat Roof Repairs Across South Wales
Flat roofs often show signs of wear before they fail completely. If you’ve noticed leaks, pooling water, bubbling, cracks or loose edges, we can assess the roof and repair it before the issue spreads.
Common repair work includes:
- Fixing splits and cracks
- Re-sealing joints
- Repairing blisters and bubbles
- Patching damaged areas
- Improving drainage
- Replacing failing felt, GRP or EPDM sections
Our goal is to extend the life of your roof and protect your property from further damage.
Commercial Flat Roofing
We also work with small businesses, landlords and commercial property owners. From shop units to industrial buildings, we provide flat roof repairs, maintenance and replacements using systems suited to larger spaces.
