Expert Commercial Roofing That Keeps You Trading
Commercial roofing is roofing work on business premises: shops, offices, industrial units, warehouses and rental properties, rather than homes. If you need commercial roofing in Cornwall, the difference isn't just scale: it's the flat-roof systems many commercial buildings use, the need to keep the premises trading while the work's done, and the written reports landlords and managing agents need for their records.
That's where the right roofer earns their place. Steve looks at the building properly, gives a straight answer on what it genuinely needs, and plans the work around your hours so you stay open. He's NVQ-qualified in roofing and leadwork and hot-works insured, so the flat-roof systems and the lead detailing that commercial roofs depend on are both done to last, and you get a clear written quote and a paper trail you can hand straight to your landlord or agent.

Why choose us
Why Choose Us for Commercial Roofing

Steve is NVQ-qualified specifically in leadwork and hot-works insured, so torch-on work and lead detailing are done safely and built to last.

How Our Commercial Quotes Work
Every commercial building is different, so an accurate price starts with a proper look. What shapes a commercial roofing quote is the size and type of roof, the system needed (GRP, EPDM, slate or tile), how the roof is accessed safely, how much leadwork and detailing is involved, and whether the work needs phasing around your opening hours.
What you can always count on: a free inspection, a clear written quote with the work and materials set out, written reports for landlords or managing agents where you need them, and an expert recommendation on whether to repair, recover or maintain, so you know exactly what's being done, why, and what it costs before any work starts.
