Flat Roofing
We specialise in advanced flat roofing systems for commercial and residential properties. Our solutions include single-ply membranes, hot melt asphalt, and liquid waterproofing. Each installation combines durability with compliance to ensure long-term protection against weathering and structural damage.
Single Ply Roofing
Our single-ply roofing services utilise high-performance materials like Sika Trocal and PVC systems. These lightweight, flexible membranes provide excellent waterproofing and energy efficiency. Ideal for both new builds and refurbishments, they offer rapid installation with minimal disruption.
Green Roofing
We design and install sustainable green roofing systems that enhance biodiversity and improve thermal performance. Our solutions include sedum roofs and biodiverse systems tailored to project requirements. These installations contribute to environmental goals while extending roof lifespan.
Roof Surveys
Our comprehensive roof surveys identify issues and recommend maintenance strategies. Using technical expertise, we assess waterproofing integrity, insulation performance, and structural condition. Reports provide actionable insights to prolong roof longevity and prevent costly failures.
Gutter Systems
We supply and install durable gutter and downpipe systems to manage rainwater effectively. Our solutions prevent water ingress and structural damage, incorporating modern materials and designs suited to both traditional and contemporary buildings.
