Professional GRP Fibreglass Roofing Services in Amersham
High class roofing provides expert GRP fibreglass roofing installation and repair across Amersham and the surrounding 15-mile radius. Led by Jimmy Frankham, our team specialises in delivering high-performance Glass Reinforced Polyester systems that create a completely seamless, waterproof membrane. This modern approach is ideal for residential extensions, dormers, and balconies where traditional materials often struggle to maintain a watertight seal over time.
Why Choose Us
Why choose GRP for your flat roof?
Unlike traditional multi-layer mineral felt, GRP is a cold-applied system that eliminates fire risks during installation. Because it is applied as a liquid and cures into a solid, glass-reinforced sheet, there are no seams or joints that can peel or split under thermal expansion. This makes it an incredibly durable choice for flat roofs in Amersham that need to withstand heavy rain and UV exposure without degradation. GRP is also resilient enough to handle light foot traffic, making it a practical option if you have a balcony or a roof terrace.

Who We Are
Addressing common flat roof issues in Buckinghamshire
Many homeowners in Amersham experience problems such as pooling water, sagging decks, or failing joints on older roof extensions. We diagnose these issues by inspecting the underlying timber structures and ensuring the drainage falls are sufficient to shed water away from the property. When we install a new GRP system, we ensure the perimeter upstands and flashings are correctly dressed, preventing water ingress at the wall abutments which is a common failure point in older roofing designs.

01256 639416Building regulations and thermal efficiency
When we undertake a full flat roof replacement, we strictly adhere to Building Regulations Part L regarding thermal performance. If we are replacing the roof deck, it is often the ideal time to upgrade your roof insulation to modern U-value standards. By combining a GRP fibreglass finish with compliant thermal insulation, you can significantly reduce heat loss through your extension while enjoying a roof that requires virtually no ongoing maintenance compared to aging bituminous products.
