Caravans, motorhomes and buses face the same moss, mould and grime issues as house roofs — often worse, given the time these vehicles spend parked under trees or tucked away in storage between trips. Without regular sun exposure and movement to keep growth in check, vehicle roofs can build up moss and grime faster than a stationary home ever would.
Our treatment removes this growth and protects vulnerable roof seals and materials, helping prevent leaks and extending the life of your vehicle’s roof between trips. It’s a straightforward way to protect a vehicle that represents a serious investment, whether it’s used every weekend or stored for months at a time.
Vehicle roofs face a different set of conditions to house roofs, and those conditions work against them.
vehicles parked under trees or in storage for months give moss and mould extended time to establish.
roof seals and seams on caravans and buses are more exposed to moisture damage than solid house roofing.
build-up often goes unnoticed until the vehicle is brought out for a trip, by which point it's had months to take hold.
Left untreated, this build-up doesn’t just affect appearance — it puts roof seals and seams at risk of leaks right when you need the vehicle most.
Rather than treating a vehicle roof the same as a house roof, we adapt our approach around the materials and seals involved.
We check the vehicle’s roof material and seal condition, identifying any areas that need extra care before treatment begins.
