Roof Cleaning Sydney
Roof cleaning in Sydney is maintenance work that pays for itself. Moss and lichen trap moisture against tiles and Colorbond, accelerating cracking, rust and membrane failure. Soft-wash treatment kills growth at the root, clears debris from valleys and ridges, and flushes gutters so water moves freely. Blox Maintenance Worx handles commercial roof cleaning across The Hills, Norwest, Parramatta, North Shore, and Northern Beaches for strata managers, building owners, and property managers who need documented results, not a quick spray and invoice.
What We Clean
- Concrete and terracotta tile roofs: soft-wash treatment with post-clean rinse
- Colorbond and metal roofing: low-pressure wash safe for paint and coatings
- Moss and lichen removal from valleys, ridges and around penetrations
- Leaf litter, debris and built-up grime cleared from all roof surfaces
- Gutters flushed as part of every roof clean to ensure drainage runs freely
- Pre-sale and pre-lease cleans to presentation standard
- Annual and biannual maintenance programs for strata and commercial buildings
- Before-and-after photo documentation sent the same day

Frequently Asked Questions
Do you clean tile and metal roofs?
Yes, both concrete/terracotta tile and Colorbond/metal. We adjust pressure and chemicals to suit the surface so no coating or paint is damaged.
Will high pressure damage my roof?
We use soft wash (low pressure plus chemical treatment), not high pressure. Safe for tiles, paint and coatings. High pressure strips surface coatings and forces water under tiles.
How often should a commercial roof be cleaned?
Every 12 to 24 months depending on tree cover and exposure. Buildings in heavily treed areas or near the coast benefit from annual cleaning to prevent moss and lichen taking hold.
Do you clean gutters at the same time?
Yes. Gutters are flushed as part of every roof clean. Debris cleared from the roof ends up at the gutter line, so we clear it in the same visit.
Can you work on multi-storey buildings?
Yes. We work on commercial and strata buildings up to mid-rise with proper access equipment. Confirm the building height when you book and we will have the right gear on site.
Do you provide documentation for strata records?
Yes. Before-and-after photos are standard on every job, emailed to you the same day. Use them for owners corporation reports, maintenance records, or insurance documentation.
Can you combine roof cleaning with gutter cleaning or maintenance?
Yes, and most building managers book it this way. We handle the roof clean, gutter flush and any minor maintenance items in one visit under one invoice.
