Roofing in Wairau Valley: Warehouse & Commercial Roofs
Commercial roof repairs, long-run re-roofs and internal gutter replacement for Wairau Valley businesses.
Roofing in Wairau Valley
- Mainly commercial and industrial
- Commercial buildings
- Flat and low-pitch roofs
Wairau Valley is the North Shore's main commercial and light industrial area, stretched along Wairau Road and the low ground between Glenfield, Milford and Takapuna. Big-box retailers, trade suppliers, car yards, warehouses, workshops and offices fill the valley. Wairau Creek winds through it toward Milford. For a roofer this is a different world from the surrounding suburbs: big spans, internal gutters, skylights and clients who need the business to keep trading.
Homes in Wairau Valley
There is very little housing in the valley itself. The building stock is mainly warehouses, factory units, showrooms and office blocks, with the earliest dating from the 1960s and 70s and plenty of newer commercial development since. Many older buildings have been subdivided into smaller units, re-clad or extended, so a single roof can carry several generations of repairs, add-ons and plant.
The roofs we work on here
Large-span long-run steel is the norm, typically low pitch, with clear skylight sheets, internal or box gutters and parapets. Some older buildings have asbestos-cement roofing, which must be tested before anyone works on it. Common failures include corroded fixings and laps, brittle or cracked skylights, internal gutters rusting through at joints, undersized outlets and water ponding on very low pitches. Plant, ducting and solar added over the years also leave penetrations to keep sealed. Re-roofing, gutter replacement, skylight renewal and leak tracing are the core jobs.
Weather and exposure
The valley floor is low-lying and was hit hard by the January 2023 floods. On big roofs, intense rain arrives faster than undersized internal gutters and downpipes can clear it, and overflow goes straight into the building. Wind is usually moderate, but worn fixings on wide spans are vulnerable to uplift at edges and corners.
