GRP Flat Roofing FAQ's

Is GRP better than EPDM?

It depends on what your priorities are. EPDM may be more cost effective for larger areas, while GRP has better aesthetics and durability.

How long will a GRP roof last?

GRP roofing has been proven to have a long lifespan, typically in excess of 50 years.

Can you jet wash a GRP roof?

Yes, you can use a jet wash as long as it doesn't use hot water or steam, or you can equally use a garden hose to remove dirt and debris.

Can you install it over felt?

Not all systems are suitable for installation over felt, we would advise checking the individual systems or give us a call.
