Flat and Membrane Roofs in Porirua

Low-slope roofs and decks on exposed Porirua sites take wind-driven rain at the edges and upstands. Those junctions get our closest attention.

Flat and Membrane Roofs on Porirua roofs

Wind does a lot of the damage on Porirua roofs. Fixings work loose at the edges and ridges, lifted sheets let driven rain straight in, and coastal salt rusts the laps. We refix and reseal with the exposure in mind, not just the leak.

Flat and low-slope roofs do not shed water the way a pitched roof does, so small faults matter more. Ponding water, blocked outlets and failed seams are the usual causes of leaks.

The housing ranges from older long-run and tile roofs in the established suburbs to newer homes in Whitby and Aotea, so the right answer for a roof here depends very much on the street.

Building Code clause E2 requires roofs, including low-slope roofs, to keep external moisture out of the building. (MBIE, Building Code clause E2 External moisture)

What to look for

• Water ponding after rain
• Blisters, splits or lifted seams in the membrane
• Blocked or undersized outlets and scuppers

Every job follows the same steps: we look at the roof, photograph what we find, send a written quote, then send photos of the finished work. More about flat and Membrane Roofs.
