Why is rooftop waterproofing Important?
Rooftop waterproofing is crucial because it protects your building from water damage and leakage, which can result in costly repairs and structural damage. Here are some reasons why rooftop waterproofing is important:
Prevents water damage: A roof waterproofing singapore prevents water from seeping into your building, which can cause significant water damage to walls, ceilings, and floors. Water damage can weaken the structure of your building and cause mold growth, which can have a negative impact on the health of those living or working inside.
Improves energy efficiency: A waterproof roof can also improve the energy efficiency of your building by preventing air leaks and reducing the amount of energy needed to heat or cool your space.
Saves money on repairs: Rooftop waterproofing is a preventative measure that can save you money in the long run. If your roof is not waterproofed, you may have to deal with costly repairs to fix water damage and leaks.
Increases lifespan of your roof: A waterproof roof can last much longer than a non-waterproof one. Waterproofing protects your roof from damage caused by water, UV rays, and other environmental factors, increasing its lifespan.
Overall, rooftop waterproofing is an important investment for any building owner, as it can protect your property, save you money, and improve the longevity of your roof.
Common waterproofing issues
Here are some common waterproofing issues that can occur:
- Poor drainage: Water can accumulate on rooftops and in other areas due to poor drainage systems. This can cause water to seep into the building, leading to water damage and mold growth.
- Cracks: Cracks can develop in concrete, masonry, and other materials used in construction. These cracks can allow water to seep through and cause damage to the underlying structure.
- Incorrect application: Waterproofing materials must be applied correctly to be effective. If the application is not done correctly, water can still seep through and cause damage.
Wear and tear: Waterproofing materials can wear out over time due to exposure to the elements, UV rays, and other factors. This can lead to water damage and leaks.
Design flaws: Poor design can lead to water infiltration. For example, if the slope of the roof is not steep enough, water can pool and seep through.

It is important to regularly inspect your building for signs of water damage and to address any issues promptly to prevent further damage.
Our rooftop waterproofing methods
Bituminous roof torch-on waterproofing membrane
- Prepare the roof surface: Clean and dry the top of your roof before applying the membrane.
- Connect the torch equipment: The house of the blowtorch should be in good condition.
- Align bituminous rolls: We avoid wrinkling the material, and align them properly.
- Install the membrane: Apply the torch fire uniformly and slowly over the roll as we lay it
- Inspect the joints between the sheets: Ensure the joints properly adhere to the end laps of the membrane to prevent air gaps.
Polyurethane liquid membrane waterproofing
We’ve compiled a list of steps for applying a waterproofing membrane to your rooftop. We provide commercial waterproofing services to make the process easier.
- Clean out the substrate: Cleaning the surface allows a liquid applied membrane to adhere well. Pressure-wash the substrate to clean it and remove debris, dust or grease that could compromis
- Prime the surface: Apply a primer to the surface to enhance the membrane’s adhesion. Primers can also prevent the bituminous oils from bleeding through to the membrane. Before we apply the primer, we make sure the surface is dry.
- Treat the roof’s details: These details include the interior and exterior corners, wall-to-floor corners, metal flashing terminations and penetrations — such as pipes, vents and drains. Embed reinforcing fabric into the liquid membrane, or use a flashing-grade sealant.
- Apply the liquid membrane: Some liquid roof waterproofing membrane need fabric reinforcing mats underneath before installation. The application, substrate porosity, temperature and waste affect the liquid membrane’s consumption rate.
- Inspect the roof: In most projects, we need to inspect the application at each phase. We’ll check the primer’s coverage, the pull-out and mock-up, the detail treatments and the applied coating millage.

Green Roof in Singapore
It is clear that a roof can have far more value than just being used as a place for air conditioning units and others. When a homeowner includes plans for a vegetated roof can extend the roof life and can provide a patio for recreation or an improved view. On commercial structures such as offices, apartments, or hotel buildings, a green roof can provide a host of benefits:
Energy savings on heating and cooling: cooler air feed into your HVAC systems, meaning you’re going to save energy in that regard as well.
Improved stormwater management: Green roofs can help reduce stormwater, which protects the environment in many ways.
Reduced heat island effect, improved air quality: Green roofs act as natural filters, absorbing pollutants from the air and trapping them in the soil. This helps to improve air quality by reducing the amount of pollutants that are released into the atmosphere.
Reduced greenhouse gas emissions: Provide an increase in biodiversity in an area, extend the life of roofing membranes, and more.
Usable amenity space: A pleasing view.
Green roofs are an important component of keeping a building cool and helping cool the environment by reducing the heat island effect. The biggest reason roof membranes wear out is due to UV exposure and heat fluctuation. So if you cover that with a cooling thing, like a green roof, then you’re going to increase the longevity of your roof membrane.
