The coast sets our checklist in Island Bay.
We assess roofs the length of Island Bay, from the beachfront and The Parade back up the hillside streets that run toward Berhampore. We look the roof over at close range, bring in a drone where it is safe and permitted to reach the steep, high or fragile sections a ground view cannot, and follow it with a written assessment letter on what the roof is actually doing.
Island Bay's defining feature for roofing is the coast. Salt-laden air drifts inland from the south coast and works on metal roofs, fixings and flashings every day. The closer the property is to the beach, the more pronounced this gets. None of that means an Island Bay roof is automatically a problem, plenty of them are in great condition, but the wear pattern is different from the inner suburbs and that's what we look for.
Between us we have handled the full spread of Wellington roofing, long-run steel, concrete and terracotta tile, decramastic and membrane, and a good share of that work has been near the water. By the sea that experience is what counts: it is what lets us separate salt staining that is only skin deep from corrosion that has started eating into the sheet, and a membrane that is genuinely spent from one that has merely tanned in the UV.
What we typically find on Island Bay roofs
- Coastal corrosion on coated metal roofs, particularly on weather-facing southern slopes and at cut edges, laps, and fastener heads.
- Rusting fixings and fasteners, especially where galvanised rather than stainless was used on a coastal property.
- Salt-driven edge wear on long-run metal where the coating thins at folds and laps.
- Decramastic stone-chip loss on the 70s-90s homes, accelerated by salt and wind on weather-facing slopes.
- Aged ridge cap pointing on the older tile and concrete tile homes in the suburb.
- Flashing fatigue around chimneys, dormers and roof penetrations, particularly the metal flashings that take the salt-air hit hardest.
- Membrane condition on small flat-roof sections over rear extensions and decks, which can suffer UV plus salt exposure on south-facing additions.
Where Island Bay building reports stop short: On the south coast the metal is often salt-worn and brittle, and the most exposed houses sit where a ladder cannot safely reach the roofline. So the report comes back with "the roof was not accessed" or "we recommend a roofer assess the roof". That separate roofer's assessment, done at close range from the air, is exactly what we do.
