Commercial roofing demands a different approach to residential work. The stakes are higher — a leak in a commercial building can damage stock, disrupt operations, invalidate insurance, and create health and safety liabilities. Speed, reliability, and minimal disruption are non-negotiable.
AC Roofing & Carpentry Ltd provides commercial roofing services for offices, retail units, restaurants, warehouses, schools, and multi-unit residential blocks across North London. We handle flat roofs, pitched roofs, cladding, and specialist systems on commercial buildings of all sizes.
We understand that commercial work often needs to happen outside business hours. We offer weekend and evening scheduling so your business can continue operating uninterrupted while we work. We also carry comprehensive public liability insurance and provide risk assessments and method statements as standard.
Whether you need an emergency repair to stop a leak affecting your stock, a planned re-roof on a retail unit, or an ongoing maintenance contract for a property portfolio — we deliver commercial roofing services that protect your business and your investment.
Real Work

A leaking commercial roof doesn't just cause property damage — it causes business damage. Water ingress can destroy stock, damage equipment, create slip hazards for staff and customers, and force areas of your premises to close. The financial impact extends far beyond the repair cost.
Commercial property owners face additional regulatory pressures. A failing roof can put you in breach of your lease obligations, invalidate your building insurance, or trigger enforcement action from environmental health. These aren't theoretical risks — they're compliance requirements that have real consequences.
Many commercial property owners rely on reactive maintenance — only calling a roofer when something goes wrong. This approach is more expensive over time because problems are always worse (and more urgent) by the time they're noticed. A proactive maintenance programme costs a fraction of emergency repairs.
The other common mistake is hiring a domestic roofer for commercial work. Commercial roofs — especially flat roofs — use different systems, require different safety protocols, and operate under different regulations. Using a roofer without commercial experience often leads to premature failures and compliance gaps.

We install manufacturer-backed systems with independently certified guarantees.
Most commercial buildings have flat or low-pitch roofs that require specialist membrane systems. We install single-ply membranes (TPO, PVC), EPDM rubber, GRP fibreglass, and built-up felt systems for commercial applications. System selection depends on roof size, traffic requirements, and budget. For larger roofs (100m²+), single-ply membranes offer the best balance of performance, speed of installation, and cost-effectiveness.
Industrial roofs often feature profiled metal sheet cladding, composite panels, or built-up systems over steel purlins. We repair and replace all types of industrial roofing including over-cladding, gutter lining, rooflight replacement, and fixing sheet corrosion. We also install walkway systems and fall protection for buildings that require regular roof access for plant maintenance.
Retail and office roofing needs to balance performance with aesthetics and minimal disruption. We often work outside trading hours to avoid impacting customers or staff. Retail units in converted buildings frequently have complex roof geometries with multiple levels, internal gutters, and party wall flashings — all of which require careful attention to prevent leaks.
We offer annual and bi-annual maintenance contracts for commercial property portfolios. Each visit includes a full inspection, minor repairs, gutter clearance, and a condition report with photographic evidence. Planned maintenance extends roof life, prevents emergency call-outs, and provides documentation for insurance and lease compliance.
All commercial roofing work is carried out in compliance with the Working at Height Regulations 2005, CDM Regulations 2015, and relevant British Standards. We provide full risk assessments, method statements, and COSHH assessments. Our team holds CSCS cards and relevant manufacturer training certifications. Public liability insurance and employer's liability insurance documentation is available on request.
