Although your new GRP roof is designed to be maintenance free, you may decide to wash it occasionally to maintain that ‘as new’ appearance.
If it is safe to do so, the most feasible way to clean your GRP Fibreglass Flat Roof is by using a mop and bucket with warm soapy water, or cold water mixed with bleach.
Alternatively, you can use a long handled brush combined with your garden hose if the roof has not been cleaned for a long period and has accumulated some hard to move stains.
If you have one, another method is to use a pressure washer, but we would recommend that you do not use a hot steam pressure washer, because at certain high temperatures this can cause the plastic polymers to warp or deform slightly.
If you’ve had any fibreglass steps, balconies or walkways installed, again a stiff brush with a garden hose, or a pressure washer, are both ideal ways for removing algae, mould, mud and dirt from the textured non-slip finish.
