Protect your home from structural damage and restore its original kerb appeal with our specialized, non-destructive roof cleaning services. Operating across Somerset, Dorset, and Devon, we combine advanced safety protocols with proven soft-wash treatments to eliminate heavy moss and organic growth without risking the integrity of your tiles.
Many homeowners do not realise that using aggressive, high-pressure jet washing on a roof can permanently fracture delicate tiles, strip away protective factory coatings, and force water straight into the roof space. At Cleanflow Exteriors, we completely reject high-pressure roof washing. Instead, we utilise a highly effective, low-impact method that begins with regulated pressurised air to gently but thoroughly clear away heavy moss, lichen, and environmental debris from your roof surface.
Once the physical debris is cleared, we apply a premium, soft-wash biocide treatment across the entire surface. This specialized chemical solution goes to work immediately, killing off microscopic organic spores deep within the tile pores. Not only does this treatment brighten the natural appearance of your roof tiles, but it also leaves a residual shield that dramatically slows down organic regrowth for years to come, giving you long-lasting protection and peace of mind.
Leaving moss to grow unchecked on your roof is more than just a visual issue; it poses a direct threat to your property’s structure. Our firefighter-led, certified cleaning process tackles these hidden dangers, delivering key benefits that safeguard your investment, lower your long-term repair bills, and keep your home looking immaculate.
Heavy moss acts like a sponge, absorbing rainwater and keeping constant moisture pinned directly against your roof tiles. Over time, this moisture rots the underlying wooden battens and structural timbers. By completely clearing the moss, we ensure rainwater drains away properly, preventing costly internal leaks and dampness.
During winter, water-soaked moss freezes and expands directly on and between your roof tiles. This expansion causes tiles to crack, delaminate, or break away entirely. Removing the moss breaks this destructive freeze-thaw cycle, preserving the physical integrity of your tiles and extending the overall lifespan of your roof.
As moss grows and weathers, large clumps break loose and slide down the roof pitch, landing directly in your gutters. This leads to severe downpipe blockages, sagging gutter brackets, and water overflowing down your exterior walls. Cleaning the roof at the source permanently stops this debris from choking your drainage system.
A roof covered in thick, dark moss and green algae heavily dates a property and drags down its market value. Our combination of manual air clearing and biocide soft washing strips away years of stubborn environmental grime, restoring the original colour of your tiles and making the entire property look instantly refreshed and well-maintained.

Yes, high-pressure jet washing can easily crack or dislodge older tiles and strip away their protective layers. That is why we never use high-pressure washing on roofs. Our process relies entirely on regulated pressurised air and gentle soft-washing chemicals to clear moss completely without causing any physical stress or structural damage to your property.
A biocide is an industry-approved, professional-grade soft-wash treatment that we apply to your roof after removing the bulk moss. It targets and kills the invisible, underlying root systems of moss, algae, and lichen. The treatment continues to work over the following months, gradually self-cleaning the tiles with the weather and leaving a protective barrier that prevents rapid regrowth.
Because our soft-wash biocide treatment destroys the organic growth at the root level rather than just washing away the surface, your roof will stay clean for significantly longer than standard cleaning methods. Generally, our treatments keep roofs clear of heavy moss for several years, and we offer simple follow-up maintenance treatments to extend that protection indefinitely.
Absolutely. Working at height requires strict safety standards, which is our primary focus.

We are completely insured and use specialized safety rigging and access equipment to ensure the entire job is completed safely without risking your home or our team.
You do not need to worry about booking a separate service. Because clearing moss naturally causes loose debris to drop, a full gutter clearance is completely included as standard with our Ultimate Roof Care package. We make sure your gutters and downpipes are left 100% clear and free-flowing before we leave your site.
