Roof Waterproofing Auckland
Rain Shield provides roof waterproofing for Auckland homes, commercial buildings, additions, and remediation projects. We focus on membrane systems that suit the roof build-up, drainage design, substrate condition, and long-term exposure.
Flat roofs in Auckland need more than a coating
Auckland roof leaks are often caused by ponding water, failed laps, blocked outlets, low upstands, cracked substrates, or roof penetrations that were never detailed properly. We inspect the whole roof area rather than treating the visible leak as the only problem.
Flat roof leak detection
Review visible membrane defects, penetrations and drainage to identify areas requiring investigation.
Membrane roof replacement
Define the removal, substrate preparation and replacement membrane scope before installation.
TPO and torch-on systems
Compare project-suitable systems against the specified substrate, exposure and junction details.
Warm roof waterproofing
Coordinate the membrane with the specified insulation, substrate and roof edge details.
Parapet and outlet detailing
Address membrane transitions at parapets, drainage outlets and roof penetrations as part of the roof scope.
Commercial roof remediation
Plan repair areas and access with the building team, including any constraints on ongoing site operations.
Membrane systems matched to the job
Depending on the roof, we may recommend TPO, torch-on membrane, liquid-applied systems, or warm roof build-ups. The right answer depends on fall, movement, substrate, access, existing membrane condition, and how the roof connects to parapets, gutters, skylights, and cladding.
Repair, overlay, or full replacement
Small defects can sometimes be repaired, but aged membrane roofs often need a controlled replacement. We give practical advice on whether a patch is likely to last, whether an overlay is suitable, or whether full removal is the better long-term option.
