Flat and Membrane Roofs in Lower Hutt

Lower Hutt has its share of flat-roofed extensions and garages from the 1970s onwards. Most of the membrane leaks we see are at the junction with the original house, where water ponds against an upstand.

Flat and Membrane Roofs on Lower Hutt roofs

On Lower Hutt roofs we often trace leaks to original flashings on 1950s and 1960s homes, where the sealant and fixings have simply reached the end of their life. On the eastern bays, salt sitting under laps and at the edges adds rust to the mix.

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.

That split matters on a roof. A valley home in Naenae or Taita usually needs fixings, flashings and coatings that will cope with age and rain. A bayside home in Eastbourne needs materials chosen for salt as well.

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.
