There are many reasons for a leaky roof, but poor or inadequate waterproofing tops the list. And if the city or area you live in is prone to heavy rainfalls, waterproofing the roof is imperative to prevent long-term structural damage. This guide will cover everything from the importance of waterproofing to the materials required and the step-by-step process involved.
Roof waterproofing adds that extra layer of protection to ensure no water enters your walls through the roof, thus protecting your structure from water damage and rot. Waterproofing is one of the most critical steps in the roof installation process.
Before we look at the technical aspects, let’s understand why waterproofing is integral to roof maintenance.
Waterproofing your roof will ensure that, in the long run, you save a lot on the costs of repair and maintenance. Any roof or roofing material will eventually outlive its life span, but protecting it from the harsh elements of nature will prolong the roof’s life.
If you have a leaky roof, water will eventually seep into the walls of your home and gradually erode the beams and structures supporting your home. Roof waterproofing is essential to maintain the structural durability of your home.
Waterproofing, when combined with a coating of UV membrane, will act as a protective layer against the sun’s harsh rays, thereby maintaining the temperature in your home, which leads to a lower electricity bill.
A damp roof can cause mold and moss to grow not just on the roof but also on the wet walls of the interior of your home. Stained roofs and interiors do not just indicate neglect, but long-term dampness in the home can lead to potential health issues for you and your family.
Water stains on the walls and ceilings are an eyesore, and if you are in the market to sell your property, it can substantially bring down the property cost. Waterproofing will ensure that your home or property remains beautiful inside and outside.
There are many types of waterproofing materials in the market. Selecting the suitable material for your roof will depend on the external temperatures, the level of precipitation in your area, etc. Contact your local contractors for advice on the best type of waterproofing materials.
Once you have selected the material for waterproofing, it is essential to follow a step-by-step process to ensure that the waterproofing membrane sticks securely to your roof and stays durable. Knowing the basic step involved in waterproofing will help you quickly identify any faults during installation and ensure you are getting your money’s worth.
It is crucial to thoroughly clean the substrate or the roof deck and ensure it is free of debris or dust. A clean substrate will ensure that the applied liquid membrane will stick firmly to the substrate. A high-pressure washer can be used to eliminate any contaminants that can interfere with the adhesion of the membrane. Once the substrate has been cleaned, it must dry thoroughly before applying the membrane.
The next step after cleaning the roof is to prime the surface. Ensuring the primer covers the entire roof surface as it fills all the cracks is important. A primer also acts as a sealant for the roof’s surface, and it’s important to ensure that the waterproofing membrane sticks properly to the roof. If the primer is not applied correctly, it can lead to leaks in the roof, and you might have to do the process again. Again, ensure the roof’s surface is clean and dry before applying the primer.
Once you have applied the primer and the base coat, the next step is to check and seal all the nooks and corners of the roof. All the vents, skylights, and chimneys must be treated with sealants, and the edges, corners, pipes, vents, and drains. Flashing should be checked for damages and gaps, and gutters must be free from debris and waste.
The next step is to apply the waterproofing membrane of your choice. As discussed above, many types of materials are available in the market. A minimum of two membrane layers is often applied to ensure a leakproof surface. It is imperative to allow the first layer to dry before applying the next one.
The last step is to apply a final layer of primer or sealant. This locks in the waterproofing membrane onto your roof and acts as a shield protecting your roof from external elements. Allow the sealant to dry completely before exposing your roof to rain or snow.
Now that you have an understanding of the different roof waterproofing materials available in the market and the steps involved in waterproofing, you will be able to make an informed decision.
