New Zealand's leaders in commercial roof overlays.

Our roof overlay systems provide a smarter non-disruptive alternative to reroofing. They extend the life of your building with proven durability, improved weathertightness and thermal efficiency.

What is a Roof Overlay?

A roof overlay is a specialist roofing system where we install a new warm roof directly over an existing one without removing the current system. It suits weathered roofs nearing the end of their life or experiencing constant leaks.

Key Benefits:

• Zero business downtime: A new roof, with no disruptions. We install overlay systems while your business operates unaffected, protecting your staff, stock, and equipment. We shorten project timelines by communicating directly with the client.
• Improved building performance: Made with premium membranes and insulation, our overlay systems enhance thermal and acoustic performance, increase energy efficiency, and reduce energy costs.
• Cost-effective: While the initial cost of an Overlay is similar to a full re-roof, capex savings become significant when closure of the building is considered. Productivity remains unaffected while our systems cut operating costs and reduce long-term maintenance needs.
• Built to last: Our overlay systems outperform traditional reroof systems by decades.
• Safety-driven installation

Specialists in trafficable membrane coatings.

SWP Commercial is a trusted name in car park deck waterproofing systems.
​
SWP is one of New Zealand’s largest installers of liquid and concrete parking deck coatings.  In the last two years we have installed over 30,000 square metres of coating for car parks. Car Park waterproofing is undertaken for two key reasons; to protect tenanted or habited areas below from water ingress, and to protect the integrity of the reinforcing steel within the concrete slab.

Key Benefits:

• Advanced waterproofing: We install chemically engineered systems directly from Europe, designed to withstand extreme weather conditions and building movement.
• End-to-end service: We work directly with clients, managing full system design, project management, and installation.
• Remove and replace: We coat new buildings and remove existing failed systems, installing new high-performing, lightweight, fully bonded, UV-stable, waterproof systems.
• Structural protection: Water ingress can cause steel reinforcement to rust and weaken. Our systems guarantee complete waterproofing protection.
