Rooftop Waterproofing: How to Choose the Right Product and Prevent Recurring Leaks
Causes of Roof Leaks You Might Overlook
1. Leaks from Cracks in the Roof Surface
Roof leaks often occur because of cracks caused by temperature changes from sunlight, cold, and rain. These factors make the concrete roof surface expand and contract, leading to cracks. If left unchecked, water can seep through these cracks and penetrate deep into the structure, potentially causing rust over time.
2. Cracks at the Roof’s Floor and Wall Corners That Haven’t Been Fixed
The joints between the floor and walls, especially at the corners, are another risk area for leaks. Without proper treatment or waterproofing, these cracks will expand over time, allowing water to accumulate, leading to mold, algae, and leaks into the structure.
3. Leaks Caused by Installing Items on the Roof
Adding items like water tanks or other structures to the roof can create cracks that lead to leaks. Using a highly flexible waterproofing system helps prevent surface tears and reduces the risk of water entering the cracks.
4. Leaks Due to Clogged Drainage
Clogged drains are one of the easiest causes of leaks to prevent, but they’re often overlooked. Regularly check your roof to ensure leaves and debris are not blocking the drains, which could lead to water pooling and leaks.
5. Leaks Despite the Roof Being Waterproofed
Many people assume that a concrete roof is waterproof by default. However, unless a proper waterproofing system has been applied, the roof is still vulnerable to cracks and leaks, especially after prolonged exposure to sunlight and rain.
6. The deck leaks because of the use of unsuitable products.
The selection of unsuitable products for the work is a popular topic; for example, the use of cement to cover the cracks on the rooftop or filling the cracks with acrylic sealant. As time goes by, the rooftop leaks again because the plastered cement is not flexible. When exposed to the sun and rain for a long time, it is broken as before. The use of acrylic sealant to fill cracks on the deck is considered inappropriate as the acrylic sealant is suitable for filling cracks in the house or indoor cracks, which are not subject to direct sunlight.
