Flat roofs have evolved significantly in recent years. We move beyond outdated methods to offer modern, high-tech systems that are engineered to withstand the British climate, offering superior protection against leaks, pooling water, and UV damage.
We install a variety of premium flat roof systems, helping you choose the best material for your property’s specific needs and budget.
EPDM (Ethylene Propylene Diene Monomer) is a high-performance synthetic rubber membrane. It is installed in a single seamless sheet, eliminating joints where leaks commonly occur.
Lifespan: 50+ years expectancy.
Benefits: extremely flexible, UV resistant, and eco-friendly.
Best for: Large flat roofs, extensions, and commercial buildings.
GRP (Glass Reinforced Plastic) creates a seamless, hard-wearing, and aesthetically pleasing finish. It is essentially a “wet” system applied in layers that cures to form a solid, watertight shell.
Durability: incredibly tough and cannot be cut with a knife.
Finish: Available in various colours (typically grey) with a non-slip finish available.
Best for: Balconies, terraces, and roofs with complex shapes or skylights.
Modern high-performance felt is a far cry from the old “pour and roll” systems. We use a three-layer built-up system that is melted onto the roof deck for a solid bond.
Cost-Effective: One of the most affordable options for a new flat roof.
Reliability: Proven technology that is reinforced with polyester for strength.
Best for: Garages, sheds, and budget-conscious roof replacements.
