Services
Flat Roofs
Our flat roof installations combine modern materials with proven techniques to create durable, weatherproof solutions. We use OSB Smartply decking boards fixed with ring-shank nails, two layers of 2mm underlay felt, and 4mm green mineral capping felt for maximum protection. Every installation includes drip edges and perimeter upstands to prevent water ingress, with all work water-tested and site-cleaned post-completion. Ideal for both residential and commercial properties seeking cost-effective, long-lasting flat roof systems.
Lead Work
Specialist lead work services protect properties against water penetration at critical junctions. We install and repair code 4 and 5 lead flashings around chimneys, valleys, and roof edges using patination oil for durability. Our process includes precise cutting, welding, and dressing of lead sheets to create seamless waterproof barriers. Chimney lead aprons and box gutters are expertly fitted with mortar pointing or lead mate sealant, ensuring compliance with building regulations while maintaining aesthetic appeal.
New Roofs
Comprehensive new roof installations using premium materials including quarried slate, concrete slates, and fibre cement slates. We handle complete structural preparation, waste removal, and timber framework construction with waterproofing felt integration. Our team ensures proper tile alignment and secure fastening while maintaining roofline aesthetics. Services cover both traditional pitched roofs and contemporary designs, with options for bespoke tiling patterns to match property architecture and owner preferences.
Roof Repairs
Targeted repair solutions for leaking or deteriorating roofs, from minor tile replacements to extensive felt renewal. We assess damage extent, replace damaged decking boards where necessary, and install advanced waterproofing membranes. Original tiles are reused where possible, with damaged ones replaced to maintain roof integrity. Our process includes thorough inspections, cost-effective repairs, and post-completion testing to restore roof performance and prevent future issues.
Fascia Soffits & Gutters
Complete fascia, soffit, and gutter replacement using durable UPVC materials. We remove old components, install treated timber backing boards, and fit weather membranes to prevent water damage. UPVC fascias and soffits are secured with polytop ring-shank nails, while gutters are installed with proper falls for efficient drainage. All joints are sealed with silicone mastic, ensuring a watertight system that enhances property appearance while protecting against weather damage.
