Full Strip & Re-Roof

  • A full strip and re-roof is the most thorough way to restore your property’s roof to as-new condition. We remove all existing tiles, battens, and underlay down to the rafters, inspect the structure, and replace any damaged timbers before installing a completely new roofing system. This includes high-performance breathable felt, treated battens, and your choice of new roof covering—slate, clay, or concrete tiles. Every detail, from ridge and verge work to valleys and lead flashing, is finished to modern building standards. A full re-roof not only eliminates leaks and rot but also enhances insulation, energy efficiency, and the appearance of your home. It’s a long-term investment that adds significant value and protection, with manufacturer warranties and a professional workmanship guarantee for complete peace of mind.

Overlay (Re-Cover)

An overlay re-roof—sometimes called a “roof-over”—is a cost-effective alternative where the existing roof structure is sound and watertight. Instead of a full strip, we install a new layer of tiles, shingles, or roofing sheets directly over the existing surface, securing it with precision fixings and ensuring proper ventilation. This method quickly improves the roof’s look, durability, and weather resistance without the disruption of a full removal. It’s ideal for modern tiled or sheeted roofs where insulation and battens are still in good condition. We check for weak spots, ridge issues, and damaged tiles before overlaying to guarantee lasting performance. The result is a refreshed roof with improved protection and visual appeal—completed faster and more affordably than a full replacement, but still delivering years of reliable service.

Pitched Roof to Pitched Roof

    Replacing an old pitched roof covering with a new one is one of the most common and effective ways to upgrade your home. Whether you’re changing from natural slate to lightweight tiles, clay to concrete, or simply renewing your existing system, we carry out every project with precision. After removing the old covering, we inspect and strengthen the rafters if needed, fit new breathable underlay and battens, and install the chosen roof covering in line with manufacturer specifications. We also replace ridge tiles, verges, and leadwork to ensure the roof is fully watertight and ventilated. A new pitched roof not only transforms the property’s appearance but also improves insulation, weatherproofing, and energy efficiency. Perfect for residential homes, cottages, and period buildings, this type of re-roof delivers long-lasting protection with a clean, professional finish.

Flat Roof Re-Roof

Flat roofs require durable, watertight systems that can withstand years of exposure. Our flat roof re-roofing service involves stripping the old felt or membrane, inspecting and repairing the decking, and fitting a new, high-performance covering such as torch-on felt, EPDM rubber, or GRP fibreglass. Each system offers different benefits—felt is tried-and-tested, EPDM provides single-sheet flexibility, and GRP creates a seamless finish ideal for complex shapes. We ensure all upstands, trims, and outlets are correctly detailed for complete waterproofing. Flat re-roofs are suitable for garages, extensions, dormers, or commercial units, offering low maintenance and long service life. The result is a tough, leak-free surface that looks neat, performs brilliantly in all weather conditions, and adds long-term value to your property.

Warm Roof Conversion (Insulated Re-Roof)

    A warm roof conversion adds insulation above the rafters during a re-roof, creating an energy-efficient system that keeps your home warmer in winter and cooler in summer. We remove the old covering, fit rigid insulation boards, apply a breathable underlay, and install the new tiles, slates, or membrane over the top. This approach eliminates cold bridging and meets current building regulations for thermal performance—making it ideal for loft conversions or energy upgrades. A warm roof not only improves comfort and reduces heating costs but also extends the life of your roof by reducing condensation and damp. Finished with new ridge, verge, and ventilation systems, your property gains a fresh, modern roof that performs exceptionally in all seasons.

Roof Structure Conversion

    For homeowners looking to transform their property, a roof structure conversion offers a complete redesign—turning flat roofs into pitched ones, or replacing thatched or outdated coverings with modern alternatives. This type of re-roof improves drainage, insulation, and kerb appeal while adding potential loft space or structural efficiency. We handle the full process, from design and planning to timber construction, weatherproofing, and finishing. All work is carried out to structural engineering and building-regulation standards using premium materials for long-term performance. Converting to a pitched roof can significantly improve your property’s value, appearance, and energy efficiency. Whether it’s a modern redesign or restoring a traditional aesthetic, we deliver professional craftsmanship and lasting protection with a finish that complements your home’s architecture.
