Roof Cleaning - Soft Wash Moss, Lichen & Black Stain Removal

Sydney's coastal humidity, leaf litter from gum trees and prevailing southerly winds make local roofs a breeding ground for moss, lichen and black gloeocapsa staining. Left unchecked, these organisms hold moisture against tiles and Colorbond sheets, accelerating cracking, rusting and porous tile failure - often years before the roof should genuinely need replacement.

Tradetek Solutions cleans tile, terracotta, concrete and Colorbond roofs across Sydney, the Central Coast and Newcastle using the soft wash method preferred by leading roof manufacturers. We apply a low-pressure biocide solution that kills moss and lichen at the spore, then gently rinse - never blasting the surface with high-pressure water that can crack tiles, dislodge ridge capping or strip factory coatings.

Every clean begins with a height-safe inspection. Our technicians check for cracked tiles, lifted ridge caps, deteriorated pointing and blocked valleys, and photograph anything that needs attention before we start. You get a written report with before-and-after images so you can see exactly what was treated and what condition the roof was left in.

We work to AS/NZS 1891 height safety standards, carry $20M public liability insurance, and use bunded equipment to keep cleaning runoff out of your gardens, pool and stormwater. Most single-storey homes are cleaned in 3-5 hours with no disruption to your day - we ask you to close windows and we handle the rest.

Professional roof cleaning typically costs $385-$880 depending on roof size, pitch and access. It pays for itself by deferring restoration (which runs $4,000-$15,000+), improving solar panel efficiency, reducing roof cavity temperatures by up to 8°C, and protecting the manufacturer's warranty on Colorbond and modern concrete tiles. Booked clean every 3-5 years keeps the roof at its design lifespan.
