Professional Roof Moss Removal & Biocide Treatments
Every roof is assessed before work begins so the cleaning method can be matched to its material, age, condition, access requirements and level of organic growth.
Depending on the assessment and quotation, the service may include controlled moss removal, appropriate cleaning and a professional biocide treatment to treat remaining organic growth and help slow future regrowth.
- Surface-Specific Cleaning: Every roof is individually assessed before work begins so we can select a suitable cleaning method based on its material, age, condition and access requirements.
- Specialist Moss Removal: Accessible moss is carefully removed using a controlled method suited to the roof, helping clear drainage paths and reduce moisture-holding organic build-up.
-
Advanced Biocide Treatment: Where suitable and included in your quotation, a professional biocide treatment is applied after moss removal to treat remaining organic growth and help slow future regrowth.
- Professional Working at Height: Access requirements are assessed for each property, with suitable equipment and safety controls selected according to the roof, working height and surrounding area.
Roof Types We Clean
Concrete Roof Tiles
Concrete tiles commonly hold moss and organic staining within their textured surface. Controlled cleaning restores their appearance while accounting for the age and existing surface coating.
Clay Roof Tiles
Clay tiles may have a delicate, weathered or glazed finish. Cleaning is carefully controlled to remove organic growth without being unnecessarily harsh on the surface.
Artificial Slate
Manufactured slate and fibre-cement coverings can be fragile and product-specific. The cleaning approach is adapted to the covering’s surface finish, condition and fixings.
Natural Slate Roof Tiles
Natural slate is long-lasting but can be brittle around its edges and fixings. We work carefully to remove organic growth while minimising unnecessary disturbance.
Other Tiled Roofs
From interlocking profiles to less common tiled coverings, we first identify the material before confirming whether it can be cleaned safely and effectively.
What Can Be Included in a Roof Clean?
Initial Roof Assessment
We assess the roof covering, visible condition, pitch, access and level of organic growth before confirming the proposed cleaning method.
Controlled Moss Removal
Accessible moss is carefully removed using a controlled method suited to the roof covering, condition and agreed cleaning process.
Appropriate Roof Cleaning
Where suitable, the roof is cleaned using controlled equipment and a method selected according to its covering, condition and agreed quotation.
Professional Biocide Treatment
Where suitable and included in your quotation, a professional biocide treatment is applied to treat remaining organic growth and help slow future regrowth.
Gutter and Debris Clearance
Loose moss and debris produced during the cleaning process are cleared from accessible gutters and the immediate working area.
Final Check and Clean-Up
We complete a final visual check and tidy the immediate working area before the roof-cleaning service is finished.
Frequently Asked Questions
Why should I have my roof professionally cleaned?
Professional roof cleaning removes moss, algae, lichen and organic build-up that can retain moisture, obstruct drainage and detract from your property’s appearance. The proposed cleaning method and any treatment are matched to the roof’s material and condition.
Can roof cleaning damage roof tiles?
Using an unsuitable method or excessive pressure can damage some roof coverings. We assess the roof’s material, age and visible condition before recommending a controlled cleaning method. Any existing defects or particularly fragile areas may require additional care or repairs before cleaning.
How do you clean a roof?
The cleaning method depends on the roof covering, age, condition, pitch, access and level of organic growth. Where suitable, the service may include controlled moss removal, appropriate cleaning and a professional biocide treatment.
Do you pressure wash roofs?
We do not use one cleaning method for every roof. Where suitable, controlled pressure cleaning may be used with appropriate equipment. The method is selected according to the roof covering, age, condition and access requirements.
Will moss grow back after the roof is cleaned?
Roof cleaning cannot permanently prevent moss and other organic growth from returning. Where suitable, a professional biocide treatment can treat remaining organic growth and help slow regrowth. Future results vary depending on shade, nearby trees, moisture and the roof’s surroundings.
How long does roof cleaning take?
The time required depends on the roof’s size, pitch, condition, access and level of moss or organic growth. Most residential roof-cleaning jobs take between one and two days, but we will provide a more accurate estimate after assessing your property.
What is a biocide treatment?
A biocide treatment is a professional solution applied to the roof, where suitable, to treat remaining algae, lichen and microscopic organic growth. It works gradually and helps slow future regrowth, although results vary depending on shade, moisture, nearby trees and the roof’s surroundings.

⭐⭐⭐⭐⭐ I couldn’t be happier with the service from Ace Exterior Co. They did an outstanding job jet washing our commercial courtyard and professionally cleaning the roof on our outdoor pergola. The difference is incredible – everything looks fresh, spotless, and almost brand new again. From the initial contact through to completion, the team was professional, reliable, and extremely hardworking. They arrived on time, took great care with the property, and paid attention to every detail to ensure a top-quality finish. The courtyard has been completely transformed, and the pergola roof is now crystal clean, making the whole outdoor area look far more welcoming and professional for our customers and visitors. If you’re looking for a company that delivers exceptional results and excellent customer service, I would highly recommend Ace Exterior Co. We’ll definitely be using them again in the future.Posted on Google![]()
