Commercial roof wash & cleaning, Waikato
Programmed roof wash and moss, mould and lichen treatment for warehouses, distribution centres, retail centres, schools and multi-tenant commercial roofs.
- Soft wash and low-pressure cleaning for coated and painted metal roofs.
- Moss, mould and lichen treatment with pH-appropriate solutions.
- Abseil and rope access for multi-storey and hard-to-reach roof areas.
- Programmed cycles with clear reporting after each visit.
Commercial water blasting, Waikato
Commercial pressure washing and water blasting for concrete, tilt-slab, block work, car parks, loading bays, canopies, cladding and hard exterior surfaces. Where a surface tolerates pressure, water blasting is faster and more thorough than soft wash; where it does not, we swap to soft wash instead of forcing the tool.
Car parks & loading bays
Programmed cleans of concrete and asphalt car parks, loading bays, service yards and outdoor plaza areas.
Cladding & hard surfaces
Water blasting of tilt-slab, block work, canopies and durable cladding where high-pressure cleaning is appropriate for the surface.

Common questions
Do you clean roofs as well as walls and windows?
Yes. Programmed commercial roof wash, roof-treatment for moss, mould and lichen, gutter clearing and full exterior building wash are all handled by the same exterior team, so nothing falls between contractors.
Do you handle abseil and hard-to-reach exterior wash?
Yes. Access has an in-house abseil and access team, so multi-storey commercial buildings, canopies, atriums and hard-to-reach roof areas are covered without contracting a separate access provider.
What is soft washing and when do you use it?
Soft wash uses low pressure and pH-appropriate cleaning solutions to clean surfaces without damaging coatings, render or heritage fabric. We use soft wash where high-pressure cleaning would risk damage; we use commercial water blasting where the surface needs it.
Can you run programmed wash cycles on multi-site portfolios?
Yes. We build programmed wash schedules for portfolios and multi-site retail, industrial and commercial estates, with clear reporting after each visit and one accountable point of contact.
Which parts of the Waikato do you cover?
For multi-site portfolios we coordinate Waikato work under one point of contact together with our Auckland, Bay of Plenty and Christchurch teams. For a specific building or site, send it through and we will confirm the practical next step.
