Roof Treatment
(Mould & Lichen Removal)

Mould and lichen don’t just sit on the surface, they embed into your roof and continue to spread if not properly treated.

Our roof treatment targets these issues at the source, helping to eliminate growth and slow its return. This not only improves the appearance of your roof but also supports its long-term condition and durability.

Algae Attack

Algae attack is a treatment designed to kill and inhibit future regrowth of organic contaminants such as:

Algae

Mould

Lichen

Moss

Mildew

Bacteria

Algae attack is an exterior cleaning agent that is applied with low-pressure (soft wash) equipment. Algae attack kills growth at the root and sanitises the surface.

What you can expect from a Professional Roof Treatment?

When you book a professional algae attack service, you are paying for the right solution and the experience needed to handle and apply algae attack safely. Here’s what you can reasonably expect:

Thorough Inspection & Honest Advice

A proper assessment of the property before starting. Identifying where organic growth (mould, algae, lichen, moss) is present. Explaining whether algae attack alone will do the job, or whether it should be paired with soft wash or pressure wash for best results.

Correct Solution Handling

Use of professional-grade algae attack formulated for exterior cleaning. Accurate mixing to ensure the treatment is strong enough to kill spores but safe for surfaces. Application with low-pressure equipment for even coverage and minimal risk of damage.

Care for Surroundings

Pre-wetting and rinsing gardens and lawns to protect plants. Covering sensitive landscaping, ponds and outdoor furniture. Managing runoff responsibly.

Gentle but Effective Cleaning

No blasting or gouging – treatment is applied gently. Algae attack works into the surface, killing growth at the root. Surfaces continue to improve over time (lichen, moss and algae break down gradually).

Long Lasting Results

Algae attack prevents regrowth, keeping surfaces cleaner for months even years. Extends the life of paint, roofing and timber by reducing organic decay. Customers save money on repainting, re-roofing or frequent cleans.

Safety & Professional Standards

Proper PPE work (gloves, goggles, respirators if needed). Roof harnesses or extension equipment used for high areas. Fully insured and compliant with environmental and workplace safety standards.

Clear Customer Communication

Explanation of how algae attack works-not instantly like pressure washing but longer lasting. Honest timeframes-some surfaces take days or even weeks to fully clear. Advice on aftercare and maintenance schedules.
