Moss, Mould & Lichen Treatments

North Shore House Wash uses a chemical 5% Benzalkonium Chloride with slow acting formulation, designed for the efficient killing of Moss, Mould & Lichen. When applied the chemical penetrates spores over a period of 3 to 4 hours. This penetration results in the gradual withering and dying of the Moss or Lichen, and provides long acting protection from re-growth. Time will vary depending on pitch of roof, roofing material and amount of rainfall. North Shore House Wash is among the best mould removal company in Auckland.

Treating Roofs from Moss, Mould & Lichens

Along with Roof-Washing which achieves instant results, North Shore House Wash offers a moss, mould & lichen roof treatment, which over time cleans your roof’s surface and prevents regrowth . Our roof treatments are environmentally friendly and biodegradable so the treatment won’t harm your gardens or cause damage to the environment.Lichen can eat away at the existing coating on the roof and lift off the paint, leaving lichen scarring on the roof surface. If left untreated can result in lichen can penetrate the roof surface which can cause costly repairs. Our mould cleaning method is safe, eco-friendly, and effective.

Roof Treatment Cleaning Auckland

North Shore House Wash takes care

When traditional roof cleaning methods can’t be implemented, where access proves difficult or too costly to use traditional pressure washing methods, a roof treatment service is required to ensure your roof surface stays in good condition.

We use a low-pressure technique to apply a roof treatment solution, which gradually and safely removes moss, mould & lichen from your roof. This way, we ensure that no damage is done to your roof’s surface.

A roof treatment is usually the best option when your roof has moss growth. This is where I apply a moss killing chemical to your roof which takes about 3 hours to penetrate the moss and its roots. The treatment is left on the roof and over a period of a few months, the moss will naturally come off the roof leaving it moss free for up to 2 years or sometimes longer. This is the best option for removal of moss as a roof clean will not remove the moss permanently.
