Rooftop Contractor
Most roofs in Singapore are constructed using reinforced concrete which is known to have pores or capillary tracts. Concrete is known to be inherently weak in tension; cracks and voids can form due to thermal expansion, contraction, and shrinkage. As a result, water will seep through these voids. Therefore, waterproofing is required to keep the roof water-tight since they are exposed to the weather.
Roof waterproofing is the layer of extra protection added to your roof that ensures no water gets inside your home and causes the walls or support beams to rot. Roof leakage in Singapore is common, there are many causes of roof leaks, with inadequate roof waterproofing at the top of the roof.
Rooftop Solution Effectiveness
To be effective it is essential to clear surface water as rapidly as possible from the roof to avoid ponding or stagnation of water on the roof. Water ponding on a roof is a main cause of deterioration because variation in temperature between the wet and dry areas of the roof can cause different temperatures movement. Any trapped moisture will exert itself directly beneath the waterproofing membrane. If this vapor pressure is not released or vented sufficiently, the build-up pressure will begin to form a blister on the membrane itself and residual dampness on the underside of the roof. When the waterproofing membrane has suffered an irreversible stretch and a dry surface cannot be achieved within a reasonable period, an alternative method of waterproofing membrane should be considered.
The waterproofing membrane is the most important component of the roof as it serves the main function of keeping water out of the building. Waterproofing not only provides an effective treatment for leaking roofs but also gives good insulation. It is UV resistant.
Untreated water seepage through the roof reaches your building structure and can lead to the growth of mould and mildew, which can impact the quality of the indoor air. Consequently, it will lead to severe health concerns for family members, especially the elderly and children such as wheezing, eye infection, respiratory infection, skin irritation, and asthma.
Rooftop waterproofing contractors have several roof waterproofing methods for application on the rooftop.
Different Rooftop Membranes
Liquid-applied membranes are commonly applied on rooftops which allowed them to set and form into a water-impermeable membrane. This membrane is seamless, semi-flexible, and easy to apply, maintain and repair. Disadvantages of this membrane are required uniform and consistent thickness application and ensuring proper curing of concrete.
Bituminous membrane waterproofing is made from asphalt with a mixture of sticky liquid to apply with a touch-on method therefore safety and fire prevention must be considered during installation. This method is used in waterproofing as it has high flexibility, breathability, and UV heat resistance for the rooftop.
Polyurethane Liquid membrane waterproofing uses coating or primer and top coating using the trowel, roller, or spray. Its stretchability and durability can last a couple of decades. The application process is fast and easy. It is more flexible than any other membrane, it fills all capillary gaps and seamless waterproofing membrane.
It is important to select the appropriate waterproofing membrane and reliable waterproofing contractor to fix the rooftop leakage. As the roof is constantly exposed to direct sun and rain, especially in Singapore’s climate.
