Liquid Membrane Roof Coating

Restore, Seal and Protect with Zenith’s Liquid Membrane Roofing System

Why simply repaint your roof when you can professionally seal it for long-term protection?

At Zenith, we specialise in roof coatings across Auckland, using high-performance liquid membrane roofing systems that give your roof a brand-new lease of life — all without the cost and disruption of full replacement. Our high-build elastomeric roof coatings are designed to waterproof, protect, and revitalise your roof, no matter the surface or condition.

Waterproof Roof Restoration – The Smarter Alternative

Our roof restoration coating system goes far beyond paint. We apply a multi-layer liquid-applied membrane that bonds to your existing roof surface, forming a durable, UV-stable and crack-resistant barrier. This is not a quick cosmetic fix — it’s a long-term weathertight roofing solution, built for New Zealand’s harsh conditions.

With full application by our licensed applicators, your roof is protected by a 10-year waterproofing warranty. This warranty is also transferable to a new property owner — a valuable selling point that adds confidence and peace of mind.

Our Roof Coating Process

Every Zenith roof coating project begins with thorough preparation to ensure adhesion and longevity:

  • Chemical treatment to eliminate moss, mould, and lichen
  • Water blasting or soft washing to deep-clean the surface
  • Rust treatment and roof repairs to halt corrosion and fix minor damage
  • Detail masking and protection to ensure neat, professional application
  • Two coats of high-build elastomeric membrane — self-priming and seamless

We apply a Class 3, flexible polyurethane waterproofing membrane that is designed to flex, bridge cracks, and expand/contract with thermal movement. This ensures watertight performance even in exposed coastal or high-UV environments.

Made for New Zealand Roofs

Our proprietary liquid membrane coating is crack-resistant, UV-stable, and certified for potable (drinking) water contact — ideal for homes with water collection systems. With up to 500% elongation, it resists peeling, cracking, and leaks over time. It’s also low in VOCs, making it safe for your home and the environment.

We offer roof coating solutions for:

  • Metal roofing (corrugated, trapezoidal, Zincalume and Colorsteel)
  • Decramastic roofs
  • Torch-on and bitumen roofs
  • Membrane flat roofs
  • Concrete roofs and parapets
  • Asbestos or fibre-cement roofing (sealed-in)
