Liquid Membrane Roofing Auckland
Fibreglass liquid membrane provides seamless waterproofing for flat roofs and butynol roof repairs throughout Auckland. We specialize in applying fibreglass and similar liquid membranes on plywood substrates.
At Membrane Applicators, we use liquid membrane primarily for butynol roof repairs - applying fibreglass coating over existing butynol to extend roof life without full replacement.

Fibreglass Liquid Membrane Specialists
We apply fibreglass and similar liquid membranes only on plywood substrates. This includes flat roofs, decks, and butynol roof overlays where the substrate is plywood.
Important: We do NOT apply liquid membrane on conventional tiled roofs or metal roofing. Our liquid membrane services are specifically for plywood-based flat roofs.
Our most common application is liquid membrane over butynol - we apply fibreglass coating over your existing aging butynol roof to repair and extend its life. This is a cost-effective alternative to full roof replacement.

Liquid Membrane FAQs
What substrates do you apply liquid membrane to?
We apply fibreglass liquid membrane on plywood substrates only. This includes new plywood installations and existing plywood under butynol roofs. We do NOT apply liquid membrane on conventional tiled roofs or metal roofing.
Can liquid membrane be applied over existing Butynol?
Yes! Liquid fibreglass membrane is an excellent solution for butynol roof repairs. We apply it directly over your existing butynol roof (on plywood substrate) to seal cracks and add a new waterproof layer. This extends your roof's life by 10-15 years.
How long does fibreglass liquid membrane last?
Quality fibreglass liquid membrane systems typically last 15-25 years depending on the product used and environmental exposure. We use premium-grade fibreglass products to ensure maximum lifespan.
What preparation is needed before application?
Proper preparation is crucial. This includes cleaning, repairing damaged areas, applying appropriate primers, and ensuring the plywood surface is dry. Our team handles all preparation as part of our service.
