Commercial roofing for industrial units, retail premises, offices, schools and warehouses across Portsmouth and Hampshire — pitched and large-scale flat roofing.
Commercial roofing isn't residential roofing on a bigger scale — it's a different job. Larger membrane systems, different insurance requirements, formal documentation (RAMS, method statements, F10 notification on bigger sites), scheduling around tenants and trading hours, and contracts that often run alongside other trades. CJH Roofing has commercial experience including work on developments of 200+ houses and various commercial sites across the south, and we run commercial work as a distinct service line: site survey and risk assessment first, detailed written tender second, scheduled work third. We cover industrial and warehouse roofing, retail premises, offices and commercial buildings, schools and educational facilities, and large-scale flat roofing in single-ply membrane and EPDM. For multi-property developments and larger refurbishment programmes we provide project management, RAMS, and coordination with main contractors and tenants. Commercial pricing is by tender — there's no useful indicative range because every commercial brief is different. Send us the brief or invite us to tender and we'll come back with an itemised written response.
