At Wizard Wash Exterior Cleans, we provide safe, effective roof cleaning and moss removal services designed to protect your roof, extend its lifespan, and prevent costly long-term damage.

Moss growth on roofs is extremely common in the UK — particularly on shaded or north-facing properties — but if left untreated, it can cause serious issues both inside and outside your home.

 

Why Roof Moss Is a Problem

Moss may look harmless, but it holds moisture against your roof tiles year-round. Over time, this leads to:

• Tiles retaining water and weakening

• Frost damage during colder months

• Tiles lifting, cracking, or slipping

• Blocked gutters caused by falling moss

• Water ingress beneath tiles

• Damp and mould forming inside the property

In many cases, persistent damp or mould indoors can be traced back to moisture entering through the roof or overflowing into walls via blocked gutters caused by roof moss.

 

Our Roof Cleaning Packages

We offer two clear, proven packages depending on the condition of your roof and the finish you want.

​

The Roof Protect Package

Moss Removal + Biocide Treatment (Includes FREE Gutter Clearing)

Our most popular preventative option, designed to protect your roof and slow future moss growth.

What’s included:

• Manual moss removal using specialist tools

• FREE gutter clearing to remove fallen moss and debris

• Professional biocide treatment to kill remaining spores

What to expect:
Moss is removed immediately, but the biocide works gradually. Over the following weeks, dead growth naturally weathers away, and the roof continues to improve over time.

Best for:
Homeowners who want a cost-effective, preventative solution focused on roof health and long-term protection.

 

The Roof Restore Package

Full Softwash Roof Cleaning (Includes FREE Gutter Clearing)

Our premium option for roofs with heavier moss, staining, algae, or lichen — delivering immediate visual results.

Our softwash process includes:

1. Manual moss removal

2. Full gutter clearing and downpipe checks

3. HS treatment to break down organic staining

4. Controlled rinse (no high-pressure blasting)

5. Final biocide treatment for long-term protection

What to expect:
By the end of the day, the roof looks visibly cleaner, brighter, and more uniform — often close to a “like-new” finish — while still benefiting from ongoing biocide protection.

Best for:
Homeowners / Landlords who want maximum visual impact alongside long-term moss prevention. 

 

Why We Don’t Pressure Wash Roofs

High-pressure washing can:

• Damage protective tile coatings

• Crack or loosen tiles

• Force water beneath the roof

• Reduce the lifespan of your roof

Our approach is safer, manufacturer-recommended, and designed for longevity — not short-term cosmetic results.

​
