New Roof Construction
A new flat roof requires precise construction to prevent standing water and thermal loss over decades of British weather. We install high-performance warm and cold GRP roof systems using 18mm OSB3 decking and continuous fibreglass matting.
When You Need New Roof Construction
You are building a home extension, garage, or dormer that requires a modern flat roof. Your existing timber roof deck is rotting and beyond simple repair. You want to upgrade from traditional felt to a seamless, long-lasting fibreglass membrane. You need a thermally efficient warm roof build-up to meet current building regulations.
How We Do It
We install new 18mm OSB3 decking and edge trims securely fastened to your timber rafters. We apply a base layer of resin and roll out 450csm fibreglass matting to form a joint-free membrane. Once cured, we sand the surface smooth and apply your chosen coloured topcoat. We issue your official product guarantee and final inspection handover documentation.
What to Expect
Most standard new roof installations take between 1 to 3 days depending on size and weather conditions, with minimal disruption to your daily routine.
