New roof timbers going on a stone barn at Fober Farm in the Forest of Bowland

Much of Lancashire’s industrial and agricultural building stock went up decades ago, and many of its roofs are now leaking, fragile or made from asbestos cement. Our roofing team surveys, repairs, over-clads or fully replaces them, from our base at Walton Summit near Preston.

We work on live sites, so production, storage and trading can carry on underneath. Every job starts with a proper survey, and many roofs can be refurbished or overlaid rather than stripped, which saves time and money.

Because our roofing and solar teams are part of one group, we can replace a roof and install solar in one programme. When we fit the roof and install the solar, both are covered by one combined 30-year warranty.

Solar panels on the new packing house roof at Lovania Nurseries

Lovania Nurseries, Tarleton

The packing-house roof was fragile cement fibre over live machinery. We replaced it so the building could carry a 50 kW solar array, with roofing and solar delivered as one project. Read the case study.

From our team

“On a lot of our roofing jobs the client asks about solar once the new roof is going on. Because roofing and solar sit in the same group, we can bring the solar team in early, design the roof fixings around the panels and install both in one programme. The client gets one point of contact, one programme and, when we do both, one combined 30-year warranty. It’s the approach I’d recommend to anyone replacing a commercial roof.”

FAQs

Your questions, answered.

Can't see your question here? Our team is happy to talk it through.

How much does a commercial roof survey cost?

We offer free initial roof surveys for commercial and industrial buildings in Lancashire. We inspect the roof, explain what we find and recommend repair, refurbishment or replacement, with a clear price.

Can you replace an asbestos cement roof?

Yes. We can over-clad an asbestos roof or remove it under the right controls and replace it with an insulated metal roof, with disposal handled properly and paperwork provided.

Can my building stay in use while you work?

Usually, yes. We plan access, safety and weather protection so production, storage or trading can carry on underneath, and phase the work where needed.

Can you add solar at the same time?

Yes. Replacing a roof is the ideal time to add solar. Our roofing and energy teams deliver both together, and when we do both they share one combined 30-year warranty.

Roof due for attention?

Book a free survey and we will tell you whether you need a repair, a refurbishment or a full re-roof, and what it will cost.
