Expert Polycarb Roofing Services in South Wales: Installation and Repair.
Looking for a reliable polycarb roof installer in South Wales? We deliver high-quality, durable polycarbonate roofing solutions perfect for conservatories, lean-tos, carports, and industrial walkways. Our local team specialises in modern, multi-wall systems built to handle the challenging Welsh climate, ensuring a bright, watertight environment for your property.
Polycarb Roofing Systems: Light & Durable for South Wales
We understand that polycarbonate roofing is the ideal solution for spaces where you want maximum natural light without sacrificing protection. In areas like Cardiff and the Valleys, these roofs must be tough enough to handle debris and temperature shifts. We offer only premium, multi-wall polycarbonate—ranging from 10mm to 35mm thickness—ensuring superior thermal insulation and impact resistance.
A polycarbonate roof is only as effective as its seals and structural support. Our team consists of specialists who ensure that all glazing bars, end caps, and flashings are perfectly fitted to prevent leaks and “sheet slippage.” This commitment to quality ensures your conservatory or carport remains a dry, usable space throughout the year, regardless of the weather.


Multi-Wall Polycarbonate
Superior Insulation. The “honeycomb” structure provides excellent thermal retention, keeping spaces warmer in winter and cooler in summer.

Solid Polycarbonate
Glass-like clarity. Offers the aesthetic of glass with 200 times the impact strength. It is virtually unbreakable and ideal for high-security or high-impact areas.

UV-Protective Coating
Longevity built-in. Our sheets feature an integrated UV-filter layer that prevents the yellowing and brittleness often seen in cheaper materials over time.
