Flat roofing remains a popular choice for modern buildings, extensions, garages, and commercial premises across North Wales. But not all flat roofs are built the same. Choosing the right type can affect not only your budget but also the roof’s durability, weather resistance, and long-term maintenance.

In this guide, we’ll break down the most common flat roof types and where each one shines.

1. Felt Roofing

Felt is a traditional and cost-effective flat roofing system. It’s built up in layers and typically finished with a mineral top coat. Felt is still widely used on smaller domestic buildings and is relatively simple to repair. However, it tends to have a shorter lifespan than more modern systems.

2. EPDM Rubber Roofing

EPDM (Ethylene Propylene Diene Monomer) rubber roofing has become increasingly popular thanks to its strength, flexibility, and 25+ year lifespan. It’s installed in large sheets, meaning fewer seams and a lower risk of leaks.

Rubber systems are also ideal for fully boarded roofs, such as those you’ll find on new builds or property refurbishments.

If you’re unsure whether your current roof qualifies for this type of system, take a look at our post on how to tell if your flat roof needs replacing.

3. GRP Fibreglass Roofing

Glass Reinforced Plastic (GRP) offers a sleek, solid surface and excellent weather resistance. It’s popular for flat roof extensions and can be colour matched to trims or gutters for a tidy finish.

While GRP is strong, it can be less forgiving in colder temperatures and usually requires a completely dry surface for installation.

4. Torch-On Felt Roofing

Torch-on systems use modified bitumen sheets, heated during installation to seal the layers together. These roofs are extremely durable and well-suited to flat-roofed commercial or utility buildings.

5. Green or Sedum Roofs

Although less common, green roofs are growing in popularity. These involve a waterproof membrane topped with soil and vegetation. They offer excellent insulation, reduce water runoff, and are ideal for eco-conscious homeowners.

Choosing the Right Option

Each roofing type has different advantages depending on the project’s size, location, and intended use. Working with professionals experienced in installing flat roofs ensures you get the best advice and finish.
