Preparation is the first step in the process of the roof waterproofing system. This step is critical because the wrong materials can cause the system to fail or re-emulsify. If your roof is silicone, don’t try to apply urethane to it because it will re-emulsify. This step is also important for flat roofs because silicone doesn’t accept other coatings.
Preparation
Surface preparation is crucial for roof waterproofing. There are three main steps to surface preparation, and each one should be carried out carefully. Identify any problems on the surface. This may include stains, contamination, loose/flaking material, and moisture. In addition, check for a strong and even finish. This step is vital in ensuring the waterproofing membrane’s long-term effectiveness. In some cases, surface preparation will require additional work, such as adding a waterproofing membrane to an existing roof.
Materials
One of the main purposes of roofing materials is to protect the house from the ingress of water. Several types of roof waterproofing are available in the market. One type of waterproofing is the diffusion membrane used on flat roofs to prevent water from penetrating the building. Differing from the traditional waterproofing methods, diffusion membranes can be installed on sloped or unsloped roofs. The main difference between these two types of waterproofing is that the former is cheaper and applies to the entire roof.
Installation
The Installation of Roof Waterproofing requires several fundamental checks to ensure quality. Each stage of the waterproofing procedure needs to be coordinated with the other MEP works, such as pipe penetration and pads. The contractor should use approved shop drawings to guide the procedure. After completing the preliminary checks, the waterproofing contractor will install the membrane and other components of the waterproofing system. The installation procedure will also include a quality control inspection of the roof waterproofing materials.
Maintenance
To make sure that your roof waterproofing remains in top condition, you need to perform preventative maintenance. Inspecting your roof and gutters should be performed at least three times a year. If you see water stains, these might indicate that the waterproofing needs repair. The problem could be the flashing or membrane, whether the stain is caused by the water draining from the roof or the gutters. Moreover, you can look for moss growth on the walls, indicating a problem with the roof waterproofing. Another indication is a higher utility bill.
