How does roof waterproofing work?

Roof waterproofing works by applying a protective layer or membrane over the roof surface to prevent water penetration and damage. Polyurethane liquid membranes or bituminous membrane waterproofing are commonly used to create a seamless, durable barrier that protects the roof and its structure from the elements.
Roof waterproofing is generally covered under insurance if the damage is caused by external factors, such as a storm. However, it’s important to confirm with your insurance provider whether the waterproofing service itself or any maintenance repairs are included in your policy.
Bituminous membranes, polyurethane liquid membranes, cementitious waterproofing, and acrylic waterproofing coatings are the different types of roof waterproofing materials. These materials offer various benefits such as flexibility, durability, and resistance to UV rays, ensuring your roof remains protected from water damage and leaks.

Yes, roof waterproofing can be applied during Singapore’s rainy season, but the application requires careful timing. Waterproofing membranes, such as polyurethane liquid membrane or bituminous membrane waterproofing, need dry weather for optimal adhesion, so applying during short dry spells is best for ensuring proper curing and longevity.
BCA Registration, CoreTrade Certification, and ISO Certification should you look for in a roof waterproofing contractor. These certifications indicate that the contractor is licensed, qualified, and follows industry standards, ensuring your roof waterproofing is handled professionally and to the highest standards.

No, you do not need to replace your roof before applying waterproofing unless there is extensive roof damage. Roof waterproofing can be applied over existing structures, including damaged roof membranes, as long as repairs are made to address cracks or weaknesses before the waterproofing membrane is applied.
The dry months are the best times of year to schedule roof waterproofing services in Singapore. Ideally, aim for the drier periods between March and October to ensure proper curing and effective application of waterproofing membranes, such as bituminous membranes or polyurethane liquid membranes.
Roof waterproofing typically lasts between 10 to 20 years, depending on the type of waterproofing material used. High-quality materials like bituminous membranes or polyurethane liquid membranes provide durable protection, extending the life of your roof and minimizing the need for frequent repairs or replacements.
