Why Choose Us

Why choose GRP over traditional flat roofing

Many older flat roofs in Elmbridge and Walton-On-Thames suffer from pooling water or perishing seams. Our cold-applied GRP roofing removes the fire risks associated with torch-on bitumen alternatives. By using a liquid resin and glass fibre matting, we create a single, joint-free surface that is extremely durable and capable of handling light foot traffic. This method not only prevents water ingress but also provides a sleek, modern finish that enhances the look of your property.

Who We Are

Compliance and thermal performance in Elmbridge

When replacing your existing roof covering, we always consider Building Regulations Part L regarding thermal efficiency. If you are refurbishing more than 25 to 50 percent of your roof area, upgrading your insulation is often necessary to meet current U-values. Our team ensures that every GRP installation is compliant, helping to retain heat inside your home while protecting the structure from the volatile British climate.

What is involved in a professional flat roof survey?

Before we begin any work, we conduct a thorough site survey to assess the condition of your roof decking and edge details. Whether you have a post-war semi-detached property in Walton-On-Thames or a contemporary extension, we look for signs of rot, incorrect falls for drainage, or failing flashings around parapet walls. This initial assessment allows us to recommend the most cost-effective solution, whether that is a targeted repair or a complete replacement with a high-performance fibreglass system.
