Your roof is constantly exposed to the harsh elements of the weather—especially in the South West UK—making it vulnerable to the build-up of moss, algae, lichen, and general grime. Not only does this affect your property’s appearance, but it can also lead to long-term damage if left untreated.
At Fortress Roof and Exterior Cleaning, we provide professional roof cleaning and coating services across the South West. Our expert team specialises in safe and effective moss removal, biocide treatments, and durable protective coatings to restore your roof’s aesthetic appeal and extend its lifespan.
In addition to roof care, we also offer a complete range of exterior cleaning solutions, including:

Our Cleaning Packages
We understand that every property is different, which is why all our jobs are quoted based on the size and condition of your roof, gutters, driveway, or patio. To make things simple, we’ve put together three clear packages to suit your needs and budget:
Why Professional Roof Cleaning & Coating is Essential
While often overlooked, maintaining a clean and protected roof is crucial for several reasons:
-
Prevents Damage: Moss and lichen retain moisture, which can lead to timber rot, cracked tiles (especially during frost cycles), and degradation of roofing materials. Algae can create slippery surfaces and contribute to water channeling issues.
-
Extends Roof Lifespan: By removing damaging organic growth and applying protective coatings, you reduce wear and tear, significantly extending the life of your existing roof.
-
Enhances Curb Appeal: A clean, vibrant roof instantly boosts your home’s aesthetic appeal and can increase its market value. Dirty, moss-covered roofs can make a property look neglected.
-
Improves Drainage: Heavy moss can impede proper water flow into your gutters, leading to overflows, damp walls, and foundation issues.
-
Saves Money Long-Term: Proactive cleaning and coating are far less expensive than extensive roof repairs or a full roof replacement necessitated by neglect.
Our Cleaning & Coating Services
Professional Roof Cleaning
We assess your roof type and the extent of contamination to determine the most suitable cleaning method:
Manual Moss & Debris Removal:
For roofs with significant organic growth, our skilled technicians meticulously scrape away thick layers of moss, lichen, and other debris by hand. This careful, non-abrasive method prevents damage to your roof tiles and underlying structures, ensuring that large deposits are removed safely before any further treatment.

Targeted Soft Washing:
After manual removal, we utilise advanced soft washing techniques. This involves applying a specialist, low-pressure cleaning solution that effectively breaks down and gently lifts away ingrained dirt, algae, lichen, and remaining moss spores. Unlike harsh pressure washing, soft washing cleans without eroding or damaging your roof’s surface, preserving its integrity and appearance.

Thorough Gutter Clearing
As part of our comprehensive service, we ensure all gutters are completely cleared of any dislodged moss or debris from the cleaning process. This crucial step guarantees proper water flow and prevents future drainage issues, protecting your property’s foundations and fascias.

Targeted Moss & Algae Treatments
Once your roof is impeccably clean, we apply professional-grade moss and algae inhibitors.
Protective Roof Coatings
For ultimate protection, enhanced durability, and a refreshed aesthetic, we offer the application of high-quality, long-lasting roof coatings. These advanced coatings provide multiple benefits:
1) Superior Weatherproofing:
Our coatings create a robust, impermeable barrier that significantly improves your roof’s resistance to heavy rain, harsh UV radiation, and environmental pollutants. This helps to prevent water absorption and prolong the life of your roofing materials.
2) Revitalised Appearance:
Over time, roof tiles can fade and become dull. Our protective coatings can restore your roof’s original vibrant colour or provide a fresh, uniform finish, dramatically enhancing your home’s curb appeal and market value.
