FAQ

What is a GRP flat roof?

A GRP flat roof (Glass Reinforced Plastic), also known as a fibreglass roof, is a durable, seamless, and fully waterproof roofing system. It’s highly resistant to leaks, weather damage, and requires minimal maintenance compared to felt or asphalt roofs.

How long does a GRP roof last?

When installed correctly, a GRP roof can last 25-30 years or more. It’s one of the longest-lasting flat roof solutions available and often outperforms traditional materials.

Is a GRP roof better than felt roofing?

Yes. GRP roofs are seamless, UV-resistant, and far more durable than felt. Felt roofs often develop cracks and require patch repairs, while GRP provides a smooth, watertight finish with no joints or weak points. It is also usually cheaper. 

Can GRP roofing be walked on?

Yes. GRP roofs are strong enough to be walked on once cured, making them ideal for balconies, terraces, or areas that require occasional access.

How much does a GRP roof cost?

The cost depends on the size and complexity of your roof. On average, GRP roofing in the UK starts from £80–£120 per m² including materials and labour. For an exact quote, we offer free consultations.

Does GRP roofing need maintenance?

Not much. Unlike felt or asphalt, GRP doesn’t crack or blister. An occasional clean and inspection is usually all that’s required.

Can GRP roofing be used on balconies and custom projects?

Absolutely. GRP is perfect for balconies, walkways, extensions, and even custom waterproofing projects like ponds or wet rooms.

Do you offer a guarantee on GRP roofs?

Yes, we provide a guarantee of 25 years on our GRP installations for peace of mind.

Is GRP roofing suitable for large commercial buildings?

Yes. GRP can be used on both residential and commercial properties. It’s lightweight, durable, and ideal for warehouses, offices, and industrial units.

Is GRP environmentally friendly?

GRP roofing is long-lasting and requires fewer replacements than traditional materials, reducing waste. It’s also free from harmful chemicals like bitumen.
