Gutter Waterproofing & Repair Auckland
Membrane lining and waterproofing for box gutters, internal gutters and parapets across Auckland — stop leaks and overflow at the source.
Internal and box gutters are one of the most common sources of hidden leaks in Auckland buildings. Because they sit within the roof structure, a small failure can send water straight into the ceiling, walls and interior without any obvious sign on the outside.
Membrane Roofing Applicators waterproofs and repairs gutters across Auckland with durable membrane linings that seal joints, corners and outlets — the exact points where gutters usually fail.

Signs Your Gutter Needs Waterproofing
Gutter leaks often show up inside the building first:
- Water stains on ceilings or the top of walls after rain
- Rust, holes or splitting seams in the gutter
- Water overflowing the back edge of the gutter
- Ponding water that sits and doesn't drain
- Peeling paint or damp near the roofline
A Continuous, Seamless Seal
A membrane lining bridges the joints and corners where rigid gutters crack and rust, creating one continuous waterproof surface. We prepare the substrate, treat corrosion and detail the outlets so water goes where it should — away from your building.
Frequently Asked Questions
Can you fix a leaking box gutter without replacing it?
In most cases yes. We treat any corrosion and install a membrane lining over the existing gutter, creating a seamless waterproof surface — usually faster and more cost-effective than a full gutter replacement.
Why does my internal gutter leak into the ceiling?
Internal and box gutters sit within the roof structure, so when a joint, corner or outlet fails the water has nowhere to go but into the building. Membrane lining seals those failure points.
Do you service commercial buildings?
Yes. We waterproof and reline gutters on both residential and commercial buildings throughout Auckland.
