Roofing Services
Flat Roofing
Across Peterborough, Spalding & Lincolnshire, and Bath, with a 20-year guarantee on every job.
Old-style felt flat roofs fail, usually at the worst time. We replace tired garage, extension and dormer roofs with modern single-membrane EPDM rubber or GRP fibreglass systems that are seamless, UV-stable and built to outlast the building regulations' expectations by decades.
Every flat roof includes proper falls so water actually drains, insulation upgrades where regulations require them, and trims and edges finished neatly, not just dressed over the old mess.

Frequently asked questions
EPDM or GRP, which is better?
Both outperform felt by miles. EPDM suits larger, simpler roofs and goes down fast; GRP gives a hard, walkable finish ideal for complex shapes and balconies. We will recommend the right one for your roof, not the one with the biggest margin.
How long does a flat roof replacement take?
Most garage and extension roofs are stripped and finished in one to two days, weather permitting.
Are flat roofs included in the 20-year guarantee?
Yes, workmanship on our flat roofing systems carries the same 20-year guarantee as our pitched roofs.
