Why Choose Us

Is your flat roof suffering from water pooling?

Pooling water is a common issue for many older flat roofs in the Hart area, often caused by poor drainage or the gradual settling of the roof deck. When water sits on the surface, it eventually finds its way through the slightest crack in the membrane or a failing seal. Our diagnostic approach involves tracing these leaks to their true source, ensuring that we resolve the root cause rather than just applying a temporary patch. By assessing the fall and drainage of your existing structure, we can recommend a repair that encourages efficient runoff and prevents future saturation of your roof timbers.

Who We Are

Modern roofing solutions: EPDM and GRP fibreglass

Many older properties in the region still rely on traditional multi-layer mineral felt, which can become brittle and prone to cracking under seasonal thermal stress. We offer modern, durable alternatives such as single-ply EPDM rubber membranes and cold-applied GRP fibreglass systems. EPDM provides excellent elasticity and resistance to UV damage, making it a reliable choice for long-term weatherproofing. For complex details or areas requiring high foot traffic, GRP fibreglass creates a seamless, rigid finish that is entirely joint-free. These materials represent a significant upgrade in durability over traditional felt systems.

Compliance and thermal upgrades for your extension

When undertaking significant roof repairs or full replacements, we ensure all work aligns with current Building Regulations. If your project involves replacing a substantial portion of the roof covering, we address Part L requirements regarding thermal insulation. Upgrading your roof insulation not only improves your home's energy efficiency but also helps regulate internal temperatures, preventing condensation and reducing heat loss. Our team is well-versed in the building standards required to keep your property compliant and comfortable throughout the year.

High quality finish and traditional leadwork

A flat roof is only as good as its junctions and flashings. To ensure a complete, watertight finish, we incorporate professional-grade Code 4 lead flashings at all abutments and chimney stacks. This traditional approach prevents moisture from creeping behind the edges of your roofing material. By combining modern membrane technology with expert lead dressing, we deliver a robust repair that is designed to last. We focus on the craftsmanship that prevents future leaks, ensuring every detail is secured correctly.
