White Roof Coatings: The Roofing System Suits To Most Roofing Membranes

Do you plan to white coat your roof, but aren’t sure if your roofing membranes are suitable for this? You’re in the right place. Here, we’ll give you all the information you need about white roof coatings and roofing membranes. When considering a white coating, you should know what type of roof membranes you have. The type of white coating you choose depends on the roofing membrane material. Read on, and see if white coatings cover your roof membranes.

White Roof Coating

White roof coatings are becoming increasingly popular for flat roofs. They offer several benefits that we will discuss later in this post. As the name suggests, white roof coatings are white. They are usually made of acrylic, polyurethane, or silicone. If you have heard about cool roofs, white roof coatings are one of them. A cool roof is an energy-efficient roofing system that reflects more sunlight and absorbs less heat than a standard roof. This helps keep your building cooler, leading to lower air conditioning costs. Tucson Rubberized Coating can offer you a solution, no matter what kind of roof your building has. We have a wide range of white roof coatings that can suit any roofing membrane.

Types of Roofing Membranes

To ensure that your white coating will adhere properly to your roofing membrane, choosing the right type of white coating for your roof is important. White coatings are not a one-size-fits-all solution. The type of white coating you choose depends on the roofing membrane material. There are three main types of roofing membranes: thermoplastic, thermoset, and metal. Let’s take a closer look at each one.

Thermoplastic Membranes

A thermoplastic membrane is a synthetic substance that softens when heated and rehardens when cooled, like polyethylene. It is used as a single-ply roofing material known for being the most challenging roofing membrane to adhere to due to how they physically break down and the residue that remains. Luckily, Tucson Rubberized Coating has a quick and easy solution for single-ply. The acrylic base coat is a white roof coating that allows for direct adhesion to single-ply membranes without needing a primer or etching rinse.

Thermoset Membranes

Thermoset membranes are made of vulcanized rubber or cured with heat and pressure. They are often black or gray. EPDM is a common type of thermoset membrane. It is a type of elastomeric roof membrane known for its durability and resistance to weathering, UV rays, and ozone. If you have a thermoset roofing membrane, you can use any type of white coating except silicone.

Metal Membranes

Metal membranes are one of the most popular types of roofing materials, and for good reason. They’re durable, energy-efficient, and can be customized to fit the specific needs of your home or business. Metal membranes come in various colors and styles, so you can find one that perfectly complements the look of your property. However, adding white roof coatings can make it more durable and energy-efficient. If you have a metal roof, you can use any white elastomeric roof coating.

Types of Elastomeric Roof Coatings

As mentioned above, white elastomeric coatings are suitable for all types of roofing membranes. Elastomeric roof coatings are classified into two main types: acrylic and silicone. Acrylic Roof Coatings Acrylic roof coatings are white, water-based latex emulsions that provide exceptional reflectivity and durability. They are also very flexible, which allows them to expand and contract with the temperature changes. This makes them ideal for use in climates with extreme temperatures. Acrylic roof coatings are also very easy to apply and can be used on all types of roofing membranes. Silicone Roof Coatings Silicone roof coatings are white, solvent-based liquids that provide superior reflectivity and durability. They are also highly resistant to UV rays, weathering, and ponding water. However, they are not as flexible as acrylic roof coatings. They should only be used on thermoset roofing membranes because they can cause the thermoset membrane to swell and delaminate.

Benefits of White Roof Coating

More and more property owners are switching to white roofs because of the many benefits they offer. Here are just a few of the benefits you can enjoy when you choose white roof coatings for your property: Reduced energy costs: One of the main benefits of white roof coatings is energy savings. White roof coatings reflect sunlight, which helps keep your building cooler and reduces the amount of air conditioning needed to maintain a comfortable temperature. Increased lifespan: White roof coatings can also help extend the lifespan of your roof by protecting it from UV rays, weathering, and other elements that can cause damage. Enhanced aesthetics: In addition to the functional benefits, white roof coatings can also improve the appearance of your property.
