Below are things to help you understand the roof waterproofing process.
Before you even begin waterproofing a roof, it is important to know what type of material your roof is made of. In Singapore, majority of buildings are characterized by flat concrete roofs which are lined with a layer of bitumen. The bitumen helps to prevent rain water from finding its way into the house. Overtime, the bitumen material cracks up and during the rainy season, water will find its way into the home.
Once you have determined the type of roofing you have, you can simply contact an expert such as CATS and request for a quotation. This will allow you to know how much the project will cost giving your time to prepare the funds. During this time, we will also advice you if your roof really needs waterproofing, and how it should be done if needed.
Have your roof inspected
As the home owner, it is advisable not to engage in DIY inspection when it comes to your roof. Before any work is done, it is wise to let the contractor inspect your roof. This will require the use of safety equipment like a ladder. The first thing the contractor will look out for is to check for damaged caulking or any unevenly applied concrete. If the contractor finds out that there are cracks on the roofs and they are more than 0.6 cm, they will be filled with caulk.
If they are wider than that, the contractor will have to conduct concrete patching in order to fill up the cracks. The area will be inspected for dryness before any coating is applied. Industrial sandpaper will be used to smoothen the surface which improves the rate of bonding.
Before any repairs are made, the roof will have to be prepared. After sanding has been done to smoothen the surface and ensure better adherence, the contractor will have to clean the roof. This will remove any dirt that will contaminate with the waterproofing material to be applied. A good scrub should do it leaving your roof dirt free and ready for waterproofing.
There are different materials used to waterproof a roof. You have a liquid membrane which is known to be inexpensive and produces fast results. It is sprayed on your roof however it can be difficult to achieve even coverage which means sections of your roof will more thickly coated. If you opt for self adhering sheet membrane, which is a form of rubberized asphalt membrane. It is expensive than the liquid membrane and requires a lot of skill to apply.
