Factors to Consider Before Using Protecting Coatings on Your Roof

Posted on: 15 November 2017


A building's roofing system is a costly investment and an integral part if the structure, and it is essential to protect it and optimize its functionality. One of the best ways to achieve this is by applying protective roof coatings to it. Roof coatings are membranes that are applied to a roof's surface and the surrounding fixtures to seal, waterproof, and protect them from inclement weather. Before applying these coatings, it is essential to consider the following factors which will help in maximizing the performance of the coatings.

Assess the condition of the roof

It is pointless to apply a protective coating to a faulty, leaking, or damaged roof. Before using the coating, ask a roofing contractor to inspect the roof and ensure that it is in excellent condition. Check the surface and gutters for leaks and look out for damaged shingles. If the roof is defective, the coatings may not deliver the expected performance. For instance, a coated roof should be energy efficient; however, if it has holes, they will act as points of heat loss, and this will affect the roof's energy efficiency. Repair the damaged parts of the roof before hiring a contractor to apply roof coatings.

Know what you need

Various types of roof coatings such as acrylic, foam, silicone, and thermoplastic are available on the market today, and they have diverse functions. Identify your needs so that you can choose the best coatings for the roof. Acrylic coats are suitable if you want to maintain a cool roof and reduce your energy costs. Silicone helps protect the roof against UV radiation while foam is used to maximize a roof's energy efficiency. Thermoplastic coatings are mostly applied on metal roofs to strengthen their resistance to harsh weather. Have these things in mind so that you can get a coating that meets your requirements.

Consider the climatic conditions

The roof is always exposed to the environment; therefore, there is a need to ensure that you have your area's climate in mind when choosing coatings. For a location with extreme temperatures during the summer and winter, you should go for coatings that offer maximum protection. In this case, acrylic and silicone can be suitable options. On the other hand, if your area has more months of rainy weather and you have a flat roof, invest in thermoplastic coats. This is because they protect the roof from pooling water. Get a product that provides maximum protection based on the climatic conditions of your area.

Finally, the performance of roof coating will depend on how they are applied. The roof's surface should be properly cleaned and prepared. Hire a qualified contractor to ensure correct application so that you can maximize the functionality and durability of the coatings.
