Identifying and Fixing Flat Roof Leaks

When a flat roof begins to fail, the source of the leak is often disguised by pooling water or deteriorating seams. Our diagnostic process involves tracing moisture back to its origin, whether that is a puncture in an EPDM rubber membrane, a stress crack in a GRP fibreglass surface, or degraded joints in an older mineral felt system. We do not just apply temporary patches; we assess the condition of the underlying deck and insulation to ensure our repairs provide a long-lasting, watertight seal.

Who We Are

Choosing Between EPDM and GRP Systems

For property owners in Addlestone looking to upgrade their flat roof, we primarily install seamless EPDM rubber membranes and GRP fibreglass systems. EPDM is an excellent choice for its flexibility and resistance to UV light, making it highly durable against extreme temperature fluctuations. Alternatively, GRP fibreglass offers a hard-wearing, joint-free finish that is ideal for surfaces subjected to occasional foot traffic or complex architectural shapes. We advise on the best material based on your specific roof structure and drainage requirements.

Why Do Flat Roofs Require Thermal Upgrades?

When undertaking a partial or full flat roof replacement, homeowners must be aware of Building Regulations Part L regarding thermal performance. If the works involve replacing more than 25 to 50 percent of the roof covering, it is often necessary to upgrade the insulation to meet current U-value standards. Our team ensures that every project we undertake complies with these regulations, effectively reducing heat loss and preventing condensation buildup within your ceiling voids.

Weatherproofing and Chimney Flashing Repairs

A flat roof is only as reliable as its weakest point, which is often where the membrane meets an upright surface. We take pride in our precision leadwork, using Code 4 milled lead for upstands, step flashings, and aprons to ensure a secure bond against brickwork. By reinforcing these critical junctions, we protect your property from wind-driven rain and moisture ingress that can lead to rot in your roof timbers. Whether you need a simple guttering repair or a complex valley detail addressed, our craftsmanship is focused on structural integrity.
