Commercial Roofing & Guttering Services for NSW Businesses

Metal roof replacement, industrial guttering, leak detection, and preventative maintenance for commercial and industrial properties.

Commercial Roofing Services

Commercial and industrial roofing requires specialist expertise, equipment, and safety systems that differ significantly from residential work. Our commercial roofing services cover:

• Metal roof replacement and re-sheeting (Colorbond, Lysaght, Fielders) • Industrial box guttering installation and replacement • Roof leak detection and repair • Flashing replacement and waterproofing • Skylight installation and maintenance • Roof safety systems (anchor points, walkways, guardrails) • Stormwater drainage design and installation

We work across factories, warehouses, retail centres, schools, aged care facilities, and multi-storey commercial buildings.

Why Choose O'Brien for Commercial Roofing

Commercial roofing demands more than technical skill — it requires operational understanding:

• Licensed and fully insured: $20M public liability, workers compensation, professional indemnity • Premium materials: Genuine Colorbond, Lysaght, and BlueScope products with manufacturer warranties • Safety systems: Full SWMS, JSA, and site-specific safety plans for every job • Minimal disruption: We schedule work around your operations, including after-hours and weekend availability • 7-year workmanship warranty on all commercial roofing installations • 24/7 emergency response for storm damage and urgent leaks

Preventative Maintenance Programs

Reactive roof repairs cost 3–5x more than preventative maintenance. Our commercial maintenance programs include:

• Bi-annual roof inspections (pre-summer and pre-winter) • Gutter and downpipe clearing • Fixing integrity checks (screw tightness, washer condition) • Flashing and sealant inspection • Photographic condition reports with recommendations • Priority emergency response for maintenance clients

Maintenance contracts are tailored to your building's age, condition, and exposure. Most commercial clients find that a $2,000–$4,000 annual maintenance investment prevents $15,000–$50,000+ in emergency repairs over a 5-year period.

Frequently Asked Questions

How often should commercial roofs be inspected? At minimum, bi-annually — before summer storm season and before winter. Properties in exposed coastal or industrial areas benefit from quarterly inspections.

Do you offer maintenance contracts? Yes. Our contracts include scheduled inspections, priority emergency response, and discounted repair rates. Contact us for a tailored maintenance proposal.

Can you work while our business is operating? Yes. We implement noise management, dust control, and safety exclusion zones that allow your business to continue operating during roofing work. For noise-sensitive environments (offices, medical), we schedule high-impact work outside business hours.
