Commercial Roof Types We Work With
Commercial and industrial roofing is a different world from domestic. The budgets, timescales, materials, access requirements and regulatory framework are all distinct. Our commercial capacity covers:
- Industrial profiled sheet — insulated composite and double-skin systems, Tata Steel Colorcoat HPS200 or equivalent, 40-year manufacturer warranty.
- Single-ply membrane — Sika Sarnafil, IKO Armourplan, Protan. PVC and TPO options. Fully-adhered, mechanically fixed, or ballasted systems.
- Liquid roofing — Kemperol, Flexitec, Polyroof. Cold-applied seamless waterproofing for complex roofs with many penetrations.
- Built-up felt — SBS modified bitumen on existing asphalt or felt roofs. IKO Armourplan as flagship system.
- Green and brown roofs — extensive sedum systems, substrate roofs for biodiversity compliance on new developments.
The right system depends on the building: an industrial unit with a 15°-pitched profiled sheet roof needs very different intervention from a flat-roofed office block or a retail warehouse with parapet walls all round.
Planned Maintenance Programmes
For commercial clients with multiple sites, we run planned maintenance programmes — annual or twice-yearly roof inspections across your estate, written reports with prioritised recommendations, and pre-agreed rates for routine remedial work. This approach shifts roof maintenance from unplanned emergency expenditure (with all the associated business disruption) to a predictable annual cost. The economics are usually strongly in favour of planned maintenance once you factor in avoided emergency repairs, extended roof lifespans, and reduced insurance claims.
Health & Safety
Commercial roofing sits squarely within the Construction (Design and Management) Regulations 2015, and we operate under CDM as Principal Contractor on the work we do. All our operatives are CSCS-carded, IPAF-trained for MEWP access, and certified for work at height. Fall protection is either passive (scaffold, edge protection) or active (harnesses with inertia reels to properly engineered anchor points). We provide the Construction Phase Plan, RAMS and accident records required under CDM for every commercial job.
For client premises where our work affects the public (retail parks, schools during term time, occupied offices), we tailor working hours, access routes and exclusion zones to minimise impact. We've worked evenings, weekends and shutdowns on projects where business continuity required it.
Typical Commercial Timescales
A 1,000m² industrial unit re-roof in profiled sheet takes 3 to 6 weeks depending on whether we strip first or overlay, and the complexity of gutters, rooflights and plant penetrations. A 500m² single-ply flat roof replacement on an office or retail building runs 2 to 4 weeks. A full school roof refurbishment is usually planned for summer holidays and takes the full 6-week break. Every project gets a detailed programme at quotation stage, with cash-flow-friendly milestone billing for larger works.
