Building, roofing and solar across Greater Manchester
One contractor for construction, roofing, renewable energy and fit-out across Greater Manchester, based around 30 miles up the M61 in Preston.
Cornerstone Group works for businesses, landlords and estates teams across Greater Manchester: Manchester, Salford, Trafford, Stockport, Tameside, Oldham, Rochdale, Bury, Bolton and Wigan. Our base at Walton Summit sits where the M6, M61 and M65 meet, so our own site teams are usually on a Manchester job within the hour.
We bring construction and civil engineering, roofing and cladding, renewable energy and fit-out together under one contract. You deal with one team and one point of accountability, not a chain of separate trades.
Our fit-out business delivered the full interior of Hotel Football, the 133-bedroom hotel beside Old Trafford, to a fixed opening date. The same group now re-roofs warehouses, installs commercial solar PV and builds extensions for industrial clients.
What we deliver in Greater Manchester
Roofing for Manchester’s industrial estates
From Trafford Park to Heywood, Bolton and Wigan, much of the region’s industrial space was built decades ago and many roofs are reaching the end of their life. We survey, repair, over-clad or fully replace them, including asbestos cement roofs. See commercial roofing in Manchester.
Solar that pays its way
Large, simple roofs and steady daytime demand make warehouses and factories ideal for solar. We design, install and maintain systems in-house and handle the grid application to Electricity North West. See commercial solar in Manchester.
One accountable team
Most projects mean stitching together a dozen contractors. We keep design, groundworks, structure, roof, power and interior in one programme with one site lead, which means fewer gaps and nobody passing the buck.

Greater Manchester questions answered.
Can't see your question here? Our team is happy to talk it through.
Do you cover the whole of Greater Manchester?
Yes. We work across all ten boroughs: Manchester, Salford, Trafford, Stockport, Tameside, Oldham, Rochdale, Bury, Bolton and Wigan. Our base at Walton Summit, Preston, is around 30 miles from central Manchester by the M61.
Are you a Manchester company?
We are based in Preston, Lancashire, close to the M6, M61 and M65. That puts most Greater Manchester sites within about an hour, so we survey, manage and attend with our own people.

That is what the group is built for. Groundworks, structure, roofing, solar, electrical work and interior fit-out can all sit under one contract with one point of accountability.
Which electricity network covers Greater Manchester?
Electricity North West operates the local network. For solar, battery storage and EV charging we prepare and submit the connection application on your behalf as part of the project.
What have you delivered in Greater Manchester?
Our fit-out business delivered the complete interior of Hotel Football beside Old Trafford: 133 bedrooms, bars, a restaurant and a rooftop pitch, finished for a fixed opening date.
