Locate the leak: If possible, find the source of the leak by observing it when it rains or using a water hose. Check the roof surface, seals around vents and skylights, and any penetrations for cracks or damage.
Clean the surface: Thoroughly clean the leaking area and the surrounding areas to remove any dirt or debris that could hinder proper adhesion of the repair materials.
Apply sealant: Use a high-quality sealant or caulk specifically designed for fibreglass repair, which is waterproof, flexible, and resistant to UV damage. Apply the sealant around the leak and any seams or joints in the roof.
Reinforce the area: To reinforce the repair, use a piece of fibreglass mesh or cloth over the sealant. Make sure the mesh or cloth is completely saturated with the sealant. This will add strength to the repair and prevent future leaks.
Smooth the surface: Once the sealant has slightly set, use a putty knife or similar tool to smooth out the surface and ensure it is level with the surrounding roof.
Let it cure: Allow the sealant to cure according to the manufacturer's instructions. This is usually at least 24 hours, but it can vary depending on the specific product used.
Test the repair: Once the repair is fully cured, test it by simulating rain conditions or using a water hose. Ensure there are no more leaks before moving on.
Regular maintenance: To prevent future leaks, regularly inspect the fibreglass roof for any signs of cracks, damage, or wear and tear. Perform necessary maintenance and repairs as needed to ensure the roof's longevity and prevent leaks.
