Roofing & Fibreglass Roofing in South London and Westminster

What is Fibreglass (GRP) Roofing?

Fibreglass roofing, also known as GRP (glass reinforced plastic), is laid as a single seamless layer with no joins for water to get through. It's lightweight, hard-wearing and well suited to flat roofs on extensions, garages, dormers and outbuildings.

Our Roofing Services

• Fibreglass (GRP) flat roofs: new and replacement flat roofs with a seamless, durable finish

Do I Need Planning Permission?

Most roof repairs and like-for-like replacements don't need planning permission. Listed buildings and homes in conservation areas may need consent, and replacing a large part of a roof can require building regulations approval, including improved insulation. We'll tell you what applies to your property.

Roofing FAQs

How long does a fibreglass roof last?
A well-installed fibreglass roof typically lasts 20 years or more, with very little or no maintenance needed.

Can my roof be repaired rather than replaced?
Often, yes. We'll inspect the roof and tell you honestly whether a repair will do the job or whether replacement is better value.

Can you fit a fibreglass roof in wet weather?
Fibreglass needs dry conditions to cure properly, so we plan the work around the weather.

Do you need scaffolding?
For most roofing work, yes. We'll include access and scaffolding in your estimate.

Can you do the roof as part of an extension or loft conversion?
Yes. We regularly build roofs as part of larger projects, so the whole job is managed by one team.
