Extension Roofs in Stockport

A new home extension deserves a watertight, perfectly insulated roof that stands up to Northern England weather. We specialize in flat and low-pitch extension roofing using EPDM rubber, high-performance felts, and GRP fibreglass across Stockport and South Manchester.

When You Need Extension Roofing Services

You are building a new kitchen, living room, or single-storey home extension. Your existing extension roof is leaking around the joins or skylights. Your extension room feels cold in winter and overheated in summer due to poor insulation. You want to convert an old felt extension roof into a modern, long-lasting rubber or green roof system.

How We Do It

We work alongside builders or directly with homeowners to design the ideal drainage and waterproofing layout. We install high-grade timber decking, vapour barriers, and rigid insulation boards. We apply your chosen premium membrane system—such as EPDM rubber or GRP fibreglass. We install lead flashings against brickwork and check all water runoff channels.

What to Expect

Extension roofing installation typically takes 2 to 4 days depending on square footage and complexity.
