Waterproofing Northern Beaches

Waterproofing in Northern Beaches

From Manly through Dee Why, Collaroy, Narrabeen, Mona Vale, Newport and up to Palm Beach, the Northern Beaches put buildings a street, sometimes metres, from breaking surf. Salt spray reaches roofs kilometres inland. East-coast lows arrive off the ocean at full strength. And half the peninsula's apartment stock is ocean-facing strata built decades before modern membrane specs existed.

Coastal work changes the spec, not just the effort. We run mineral-finished cap sheets rated for marine UV, detail every termination against wind-driven rain, and choose fixings and cappings that don't sacrifice themselves to salt inside five years. On beachfront strata buildings we handle full roof systems, balcony programmes and planter rebuilds, staged around residents and documented for committees.

For homeowners, the peninsula's rooftop terraces and ocean-view decks are our bread and butter: strip back, torch-on, flood test, reinstate, then a warranty that outlasts most of the mortgages behind them.

Whatever the building, the process is the same: an inspection with photos, a fixed itemised quote, two-layer torch-on installed to manufacturer spec, flood testing where it counts, and a warranty in writing.
