Pressure washing a roof might seem like a quick fix for moss and algae growth, but it causes serious damage that shortens your roof's lifespan dramatically. High-pressure water strips the protective granular surface from concrete tiles, lifts and cracks slates, erodes mortar from ridge tiles and chimney joints, and drives water through overlapping joints into your roof space. In Cumbria, where moss growth is particularly heavy due to the damp, humid climate, many homeowners are tempted by the instant visual results of pressure washing without realising the hidden damage being caused. We have attended numerous properties across Barrow, Ulverston, Kendal, Windermere, and throughout the Lake District where pressure washing has necessitated early roof replacement or expensive repair work that could have been avoided entirely.
Our Hypo Clean soft wash system takes a fundamentally different approach. Instead of blasting organic growth off the surface mechanically, we apply a biocidal cleaning solution at low pressure that kills moss, algae, lichen, and fungal growth at a cellular level. The solution is applied evenly across the roof surface using professional spray equipment at pressures no higher than a garden hose, ensuring zero damage to tiles, slates, mortar, or roof structure. Once treated, the dead organic matter naturally washes away with rainfall over the following weeks, revealing the clean roof surface beneath without anyone having to walk on or scrub the roof covering. The biocidal treatment also leaves a residual protective effect that inhibits regrowth for years afterwards.
While roof cleaning is our most requested soft wash service, the Hypo Clean system is equally effective on rendered walls, pebbledash, brick, stone, timber cladding, gutters and fascias, driveways, patios, and garden walls. Cumbria's damp climate means virtually every external surface eventually develops green algae, black mould, or orange lichen that detracts from your property's appearance and can cause material degradation over time. Our soft wash treatment addresses all of these organisms safely and effectively, restoring your property's kerb appeal without the risk of damage. As members of the Roofing Trade Association and verified through the Lancashire County Council Safe Trader Scheme, we apply all treatments responsibly with full consideration for surrounding vegetation, drainage systems, and the environment.
