The 8 Options for the Best Waterproofing in Singapore
Is your home suffering from a leak? If so, you better have it checked by waterproofing specialists as soon as possible instead of waiting for things to get worse.
So here, we came up with the list of companies that offer the best waterproofing in Singapore after combing through the entire island. We included those that are open to both residential and commercial spaces.
Before we proceed to our picks, we’ll look into the cost of waterproofing on the island. This will help you decide which waterproofing company from our list to go for.
The Cost of Waterproofing in Singapore
The estimated cost of roof waterproofing in Singapore is somewhere between $3 to $10 per square foot measure. It’s common for roofing services anywhere to be charged based on the size of your roof, so the larger it is, the more expensive it is to repair.
However, based on our research, it’s better to take this average with a grain of salt considering that there are multiple factors that dictate the actual cost.
Aside from the experience of the waterproofing company, the other two factors that play a huge role in determining the price are the type of roof and waterproofing materials.
Let’s take a closer look into how these two factors affect the cost of waterproofing services on the island.
Type of Roof
The three common types of roof found in Singapore are metal, RC, and pitched roofs. Since it’s a tropical country, these are the roofing materials that can protect our rooms during summer months.
Metal is the most common out of all three because it’s cheap, lightweight and easy to install. The only problem with it is that it’s more prone to corrosion and leaks because of its composition.
The extreme weather in Singapore can easily weaken the quality of a metal roof, so you’ll definitely end up spending money for its maintenance.
RC, which is commonly found on HDB flats, is also prone to leakage because of its flat structure, so it’s more likely to have puddles of water.
Its porous nature makes it even more prone to leaks because the concrete expands due to the heat and cold, which may lead to cracks.
Lastly, a pitched roof is less likely to have leaks because its overlapping structure allows water to slide down the drainage easily. When it gets damaged though, the cost is higher than repairing a metal or RC roof because of its structure.
Waterproofing Materials
There are multiple materials a technician can use to waterproof your roof. Some materials are more expensive than the others.
The cheapest material used in waterproofing is foil. It’s a specialised waterproof foil that can keep water from penetrating into the roof.
Other cheap waterproofing materials are joint sealant and waterproof paint. Joint sealant is an elastic material that’s plastered on a roof to seal gaps and cracks, while waterproof paint needs to be applied at least four times for durability
If you want more durable waterproofing materials, then go with waterproofing membranes. These are thin, water-tight roof layers that can completely prevent water from seeping through the roof.
The two most common types of waterproofing membranes are torch membrane and liquid membrane.
Torch membrane is a solid material made of modified bitumen and designed to withstand punctures. It’s flexible and resilient enough to go against the harsh weather in Singapore.
Meanwhile, liquid membrane is applied on the surface of the roof using either a brush or a spray equipment. It then solidifies upon drying, giving the roof extra protection from cracks and leaks.
What makes waterproofing membranes the perfect choice is that they can not only repair leaks and cracks but prevent them from appearing in the first place as well. However, they’re more expensive compared to the others.

Customer Reviews
With an average rating of 4.7, Prima Seal is one of the best-reviewed waterproofing services on the island. Here are some reviews:
“My master bathroom failed HDB’s water test. The 2 options I had was to accept the Home Improvement Program’s (HIP) upgrading for only $250 or get my own contractor to waterproof it. I decided on Prima Seal Waterproofing after googling because their website explained in detail the whole process of chemical infusion treatment without hacking existing tiles. Made an appointment for site inspection prior to the fixing date for treatment. The treatment and cleanup took 5 and a half hours. Most importantly, it passed the water re-test 2 weeks after treatment. And saves me the hassle and inconvenience of having to undergo hacking and dust for 10 days if I were to accept HDB’s HIP. Great job and service by the Prima Seal Waterproofing team!” -Errol Lim
“My water leakage problem was a bit challenging and it took three treatments to finally rectify it and help me pass the HDB HIP water test. Throughout the process, Jason and his team were patient, committed and provided professional advice and competent service. The workers who carried out the treatments were polite and efficient, and always kept the place clean after finishing their work. I would highly recommend Prima Seal if you need a reliable company to help you with your water leakage problem!”
