When considering flat roof insulation, it is essential to understand the two main methods of construction. At Lancashire Roofing Specialist, we generally recommend a Warm Roof system for its superior performance, but we assess every project on its own merits.Warm Roof Construction: In this system, the insulation is placed on top of the roof deck. This keeps the entire structure at a temperature similar to the interior of the house, effectively eliminating the risk of condensation. It is the most efficient method and is the gold standard for modern extensions.Cold Roof Insulation: This involves placing insulation between the joists, leaving a gap for ventilation. While often cheaper to install, it requires precision-engineered ventilation to prevent moisture build-up, which can be challenging in the humid Lancashire climate.We provide comprehensive advice to homeowners in Preston, Burnley, and Clitheroe, ensuring you choose the system that fits your budget and the structural requirements of your home. We handle everything from vapour control layers (VCL) to the final waterproofing membrane, ensuring a seamless finish.
