Replacing or repairing a flat roof requires precision, meticulous planning, and an understanding of modern roofing dynamics. When you contact NTL Roofing, we begin with a thorough assessment of your existing roof structure. We look for common signs of failure such as pooling water, sagging decking, or split felt.Next, we provide a clear, honest quote with zero hidden fees. Once approved, our fully insured team carefully strips away the old, compromised materials while maintaining a strict clean-site policy. We then inspect the underlying substrate, usually OSB3 timber boards, replacing any compromised sections to ensure a structurally sound foundation.Finally, we apply your chosen waterproofing system with seamless precision. Special attention is paid to crucial upstands, drip edges, and flashings where the roof meets the wall, as these are the areas most vulnerable to water ingress. For urgent issues, we also offer rapid emergency roof repairs to secure your property immediately.

Modern flat roofing has evolved significantly, offering incredible longevity and aesthetic appeal. At NTL Roofing, we specialise in three premium systems tailored to your specific needs and budget:EPDM Rubber Roofing: Ethylene Propylene Diene Monomer is exceptionally durable, boasting a life expectancy of up to 50 years. It is highly UV resistant, completely seamless for most domestic applications, and provides maintenance-free protection.GRP Fibreglass Roofing: Glass Reinforced Polyester delivers a tough, seamless, and highly attractive finish. Because it cures into a solid structural layer, it is incredibly resistant to foot traffic, making it the perfect bespoke solution for balconies and roof terraces.High-Performance Torch-On Felt: A highly cost-effective and traditional approach using modern multi-layer bituminous felt. Applied with a structural torch, it creates a highly resilient and weather-resistant barrier.Whichever system you choose, our meticulous installation guarantees lasting watertight integrity.

Upgrading a flat roof is not just about keeping the rain out; it is also about improving thermal efficiency. Under Part L of the UK Building Regulations, if you are replacing more than 25% of your flat roof, you must upgrade the insulation to meet modern thermal standards.Our expert team takes the hassle out of regulatory compliance. We specialise in converting outdated cold roofs into energy-efficient warm roof systems. By installing rigid insulation boards above the timber decking but below the waterproofing membrane, we prevent condensation build-up and significantly reduce your heating bills.For clients in conservation areas or heritage properties around Wiltshire and Bath, we carefully navigate local planning requirements, ensuring our flat roofing installations respect the architectural integrity of your historic building.
