If you own a flat roof, you know the importance of keeping it well-maintained to prevent water damage. Waterproofing your flat roof should be a top priority, especially during the rainy season. A leaky roof can cause significant damage to your property and cost you a lot of money in repairs. Hence, here are some tips and tricks to help you waterproof your flat roof effectively.

Before you begin waterproofing your flat roof, it is essential to clean the surface. A dirty roof can prevent adhesion of the waterproof coating and lead to an ineffective waterproofing job. Start by sweeping off any dirt and debris on the roof surface, and then use a power washer to remove any stubborn stains. Make sure all debris is removed before proceeding to the next step.

Inspect your flat roof for signs of damage such as cracks, holes or punctures. This is key in identifying the areas that will require immediate attention.
