Gentle Roof Cleaning Using the Marshall Air Pro System
At Alfresco Exterior Cleaning, we provide specialist roof cleaning using the Marshall Air Pro compressed air system. This method is particularly suited to delicate roof coverings such as natural slate, Cotswold stone tiles, and older roofs where a gentler approach is required.
Over time, moss, algae and lichen can build up on your roof. As a result, your property can begin to look tired and neglected. Furthermore, moss holds moisture against the roof surface which can accelerate the ageing process of roofing materials.
Rather than using aggressive cleaning methods, the Marshall Air Pro uses controlled compressed air to safely remove moss and debris. Consequently, we can achieve excellent results while significantly reducing the risk of damage to fragile roof coverings.
Once the moss has been removed, we then apply a professional roof treatment designed to suppress the regrowth of moss, algae and lichen. In addition, the treatment continues to work long after we have left your property, helping to keep your roof cleaner for longer.
Unlike some roof cleaning methods that promise instant results, our treatment works gradually. Therefore, the full effect is typically seen within 6 to 9 months as rainfall and natural weathering remove any remaining organic staining. As a result, your roof will continue to improve in appearance over time.
Ultimately, the result is a cleaner, healthier-looking roof that can remain free from significant moss growth for up to 5 years.
