These days there are several ways for waterproofing work. People use different types of sealant, paint coats and other ways to waterproof their roof.
Why waterproofing work is important?
The reason why everyone should consider waterproofing work for their roof is because it can have a long-term benefit. Having liquid applied membranes have proved to be a feasible, economical and more environmentally friendly solution and that’s why it’s getting popular. In layman’s words, these waterproofing work for roofs are referred to as coatings for roofs. We may think that they are all the same and offer waterproofing for roofs but only a roofing contractor knows that each coating has its own pros and cons.
Components of waterproof roofing
The categories of liquid roofing sealants include elastomeric, polyurethane, silicone, urethane, and PMMA. Most of the time, roof coatings come in white color. It is kind of reflective of UV rays on the roof that redirect away some of the UV rays and lower the temperature of the roof during direct sun exposure. This is eventually cool off the roof.
Having a new roof is beneficial as compared to fixing an old roof. It could be hazardous to health and the environment. Replacement is kind of expensive, but it is worth it. Roofs can last many years before they are damaged enough to be replaced but they do require maintenance.
Here we will be discussing some concerning things for waterproofing roofs.
What preparations are needed before waterproofing a roof?
First, you have to consider the condition of the roof. Is it worth replacing or minor fixes would do the job? You have to decide for yourself. Now, you need to know which material is compatible with the roof. A roof could be made of ply, cement, or concrete. Once they make a roof, they usually apply some sort of waterproofing sealant. It could be silicone, urethane, or acrylic. You need to use exactly the same roof sealant or something that works well with the previous coating. The idea is to use sealants that have adhesive properties with the previous one. If you try different coating, they may not sit well, and you will end up with the same problem within weeks.
Another important thing is to clean the roof surface. You need to take out any old, damaged pieces of roof, leaves, debris, dust, and anything else on the roof. In the presence of debris and dust, there is a chance that the new coating won’t stick. There has to be a clean bare surface for the best results. For cleaning flat roofs, experts suggest pressure washing using detergents. The pressure washing will eliminate the bond breakers that are typically not visible at first glance.
Then comes the step of priming the surface for waterproofing treatment. This process is done to enhance the adhesion of the surface. Primers also aid to block leakage of the bituminous oils from the existing roof. For best results, the surface has to be dry. For this, many roof contractors such as R&D roofing use air blowers or torches.
After the necessary preparation, sealants are applied.
