How to care for a fibreglass caravan roof

Ensuring your caravan roof stays in tip top condition will not only increase the longevity of the roof but keep it looking great. A caravan roof is normally constructed from fibreglass, a lightweight and durable material. This will deteriorate over time, due to unpreventable things, such as sunshine, rain, snow and debris. All these elements will erode the protective coat from the fiberglass and penetrate into the roof. Therefore regular maintenance is imperative for a long lasting, good looking, sound and weatherproof roof.

Place a sturdy ladder or pair of steps up against the caravan. make sure the steps are secure and stable and that the caravan roof can withstand your weight. The roof will be slippery when wet, so non-slip shoes are a good idea. Using a soft broom, brush off all loose dirt and debris from the roof, making sure any air vents or roof lights are closed. This will prevent dirt and debris from being brushed into the caravan.

Using a jet washer or garden hose pipe, wash the roof with clean water to remove any remaining dust or loose dirt. Using a solution of washing up liquid in a bucket of warm water, wash the entire roof. Use a soft cloth or a soft broom; small circular motions will give the best results. Use care when going around any air vent or roof lights.

Rinse the roof with the jet wash or hose pipe. Wash off the caravan sides at the same time to prevent the dirty water from sticking. Stubborn stains such as tree sap or bird droppings may need some additional cleaning. This is best done with a soft cloth and a cream cleaner. Once again, it is best to use small circular movements. If the stains persist, increase the pressure you are using until they have been removed, then rinse off the entire roof once more. Allow the roof to dry completely in the air.

Apply an approved fiberglass wax polish (to manufacturer’s instruction) with a soft cloth, then buff it off. At this point it is advisable to inspect all seals on air vents or roof lights, look for any cracking of the rubber. Check the hinges or any moving parts and replace them if required. Check all the seams of the roof for signs of deterioration. Pay particular attention to all seams and edges.


If possible spread your weight when working on the caravan roof, using spreader boards or similar. Alternatively, an aluminium scaffold tower would be ideal. Always have someone hold the ladder for you, and if possible hand your cleaning equipment up and down for you.


Beware when working at height and on a slippery surface. Take care when sweeping debris from the roof; make sure there is no one standing below.
