Why Choose Us

Identifying Common Flat Roof Failure Points

Flat roofs, particularly those covered in traditional multi-layer mineral felt, are susceptible to cracking, bubbling, and seam failure as they age. In Sunbury-On-Thames, we frequently encounter issues with ponding water that compromises the roof structure and leads to internal damp. Our diagnostic approach involves a thorough inspection of your roof surface, upstands, and flashings to trace the exact point of entry. Whether it is a minor puncture in an EPDM membrane or deteriorating mortar around a chimney stack, we pinpoint the source before recommending the most effective repair.

Who We Are

Modern Solutions: EPDM Rubber and GRP Fibreglass

When simple patches are insufficient, we offer modern, robust alternatives for your flat roof. For many residential projects, we recommend EPDM rubber roofing due to its exceptional elasticity and long lifespan in the UK climate. Alternatively, GRP fibreglass provides a seamless, joint-free finish that is ideal for balconies or areas subject to occasional foot traffic. Both systems offer superior durability compared to older felt systems and are designed to withstand the high wind gusts often experienced near the Thames Valley.

Building Regulations and Thermal Upgrades

Property owners planning a significant roof replacement should be aware of Building Regulations Part L. When replacing more than 50 percent of a roof covering, current standards require an upgrade to your insulation to meet modern thermal efficiency requirements. We ensure all our works comply with these regulations, helping you keep your home warmer and reducing energy costs. We also use high-quality, code-compliant materials, including Code 4 milled lead for all essential flashing, to ensure your roof is properly weather-sealed against the elements.
