Roof Waterproofing in Singapore

In Singapore, where the cost of housing is incredibly high, roof waterproofing is not only an excellent way to prevent leaks in the home, but is also an essential process.

In terms of house prices, Singapore is currently ranked 2nd in the world, behind Hong Kong. The average price of residential private property in Singapore is about *1,185,740 SGD (874,372 USD). As real estate is so expensive in Singapore, it makes sense to have roof waterproofing installed in order to protect the strength, integrity, and value of your property.

The rain in Singapore is light to heavy all year round since it is a tropical country. A roof can be seriously damaged by rain, strong heat, and wind. During the rainy season, roof cracks can develop into leaks, which can cause a multitude of problems, such as damaged furniture and electrical appliances, weakening of the walls and overall structure of your house, as well as health problems caused by the formation of mold and mildew, which cause respiratory problems.

A roof waterproofing system can help mitigate all of these problems, and protect not only your home, but everything and everyone inside it as well. Singapore Waterproofing offers many options and procedures for roof waterproofing solutions. Before making decisions on your roof waterproofing needs, it is important to understand the options and procedures involved.

Different kinds of Roofs for Waterproofing in Singapore

Before we get into the different methods of waterproofing, it is important to know the different types of roofs and why the need for waterproofing in the first place, to get a better understanding of the right methods used.

Metal Roof

Metal roofs are fairly common because they are fairly cheap, lightweight, easy to install and replace. However, because they are made out metal, these roofs are prone to corrosion or rusting, due to the presence of water and oxygen, which may then lead to holes, resulting in an overall weakening of the roof.

RC Roof

The RC roof is basically a flat surface of reinforced concrete, most commonly found on HDB flats, prone to leaks due to its porous nature, and because concrete expands and contracts due to heat and cold, which may lead to cracks where water can seep through. Also, because RC roofs are commonly flat, they are more prone to having puddles of water, which makes it more prone to leakage.

Pitched Roof

Pitch roofs are designed to let water slide down to the gutter due to their overlapping structure, preventing it from accumulating on the surface. However, the unforgiving forces of nature will eventually cause wear and tear on pitched roofs, creating cracks and damage that can lead to leaks.

Roof Waterproofing Methods

• Waterproofing Membrane
  A waterproofing membrane is a thin layer of material that is water-tight, preventing water from seeping through. A waterproofing membrane is laid over the surface area in order to make it waterproof. Two common waterproofing membranes are the:
  • Torch Membrane – a pre-formed waterproofing membrane made of modified bitumen, designed to be flexible, resilient, and resistant to punctures. When installing the membrane, heat is applied to the overlapped edges using the torching method, thus creating a uniform waterproof layer on the surface of the roof.
  • Liquid Membrane – a waterproofing membrane, that is applied in liquid form on the surface of the roof in multiple layers, using rollers, brush, or spray equipment, which then solidifies when dry, creating a waterproof surface.

• Joint Sealant
  Joint sealant is an elastic, flexible moisture-curing material that is used to seal gaps and cracks on the surface of the roof, preventing water from seeping in.
• Roof Waterproofing Foil
  This is the cheapest form of roof waterproofing, making use of a specialized waterproof foil to keep water from seeping into the roof.
• Paint Waterproofing
  Waterproof paint can be applied on the surface of the roof either by hand or by spraying. Waterproof paint is very thin so it must be applied in 2 – 4 layers to make it durable.
