If you’re looking for white roof coatings, you’ll want to choose the right type of membrane. There are several types of membranes that white roof coatings can cover, each with its own benefits.
In this blog post, we’ll discuss the most common types of membranes. We’ll also talk about some of the factors that affect the adhesion of white roof coatings. If you want to consider white roof coating but are unsure if your roof is suitable, read on!
Why Use White Roof Coatings?
White roof coatings are becoming increasingly popular, especially in hot and sunny climates. That’s because white roof coatings reflect sunlight, which helps to keep your building cooler.
This can lead to lower energy bills and a more comfortable environment for your employees or tenants.
In addition, white roof coatings can extend the life of your roof by protecting it from UV damage. However, to get the most out of your white roof coating, it’s essential to check if your roof membranes are compatible with white roof coatings. This is to ensure that the white roof coating adheres properly and lasts many years.
A white roof coating system can adhere to any roofing substrate. They can adhere to newly constructed roofs, aged and deteriorating roofs, and roofs in-between. Because of its elastic properties, white roof coatings can also fill in any cracks or gaps in your roof, providing an extra layer of protection and extending your roof’s service life.
At Everlast Coatings, we have a wide variety of white roof coatings. We have a suitable white coating for the following roofing membranes:
Asphalt or Bitumen Membranes
One of the most common types of membranes is bitumen. Modified bitumen is a black, sticky substance made from petroleum products. It’s often used in roofing because it’s waterproof and can be applied to various thicknesses.
Bitumen is available in two different types: asphalt-based and coal-tar-based. Asphalt-based bitumen is the most common type used in roofing membranes, while coal-tar-based bitumen is typically used for industrial applications.
PVC Membranes
Another type of membrane is PVC, or polyvinyl chloride. PVC is a synthetic plastic that’s made from petroleum products. It’s often used in piping and electrical applications because it’s strong and durable. PVC is available in two different types: rigid and flexible. Rigid PVC is used in pipes and tubing, while flexible PVC is used in electrical applications.
TPO Membranes
TPO or thermoplastic polyolefin is a synthetic rubber made from petroleum products. It’s often used in roofing because it’s flexible and can be applied to various thicknesses.
Spray Polyurethane Foam (SPF) Membranes
SPF, or spray polyurethane foam, is a type of plastic made from petroleum products. It’s often used in insulation and roofing because it expands to fill gaps and cracks. SPF is available in two different types: closed-cell and open-cell. Closed-cell SPF is denser and more water-resistant, while open-cell SPF is more porous and air-filled.
Metal Membranes
Metal membranes are made from various metals, including steel, aluminum, and copper. Metal membranes are often used in roofing because they’re durable and long-lasting. However, you can make it more durable by applying white roof coatings.
Types of White Roof Coatings
No matter which of the roof membranes you have, there is a white roof coating that can be applied. Here are some of the most popular types of white roof coatings:
Acrylic White Roof Coatings
One of the most popular roof coatings in the roofing industry is acrylic-based white roof coatings. They are a type of elastomeric roof coating made from acrylic resin, a synthetic plastic. Acrylic-based white roof coatings are popular because they’re durable and long-lasting.
Silicone-based White Roof Coatings
Another type of white roof coating is silicone-based. Silicone coatings are made from silicone and are often referred to as “cool roofs” due to their high reflectivity. Silicone-based white roof coatings are popular because they can reduce energy costs. They can be applied to most roof surfaces, including asphalt, metal, TPO, and PVC.
Polyurethane-based White Roof Coatings
Another type of white roof coating is polyurethane-based. Polyurethane-based white roof coatings are made from polyurethane, a synthetic rubber. Polyurethane-based white roof coatings are popular because they’re flexible and can be applied to most roofing membranes.
Factors That Affect Proper Adhesion
Now that you know some of the most popular types of white roof coatings, it’s important to know the factors that can affect proper adhesion. This is to ensure that your white roof coating will last many years.
Even if your roof membranes are white coating compatible, there are still a few things that can go wrong during the application process. The three most common factors are surface preparation, application method, and cure time.
Surface Preparation: One factor that can affect proper adhesion is surface preparation. For white roof coatings to adhere properly, the surface must be clean and free of debris. The best way to prepare a surface for white roof coatings is to pressure wash it with a detergent solution.
Application Method: Another factor that can affect proper adhesion is the application method. White roof coatings can be applied with a brush, roller, or sprayer. When choosing an application method, it’s important to consider the type of white roof coating you’re using. For example, silicone-based white roof coatings are best applied with a sprayer because they’re thin and can easily be spread evenly.
Cure Time: The last factor that can affect proper adhesion is the cure time. Cure time is the amount of time it takes for white roof coatings to dry and set. Depending on the type of white roof coating, the cure time can range from 24 to 72 hours.
Conclusion
White roof coatings are a great way to protect your roof from the sun’s rays. But before you choose a white roof coating, you must know which type of membrane you have and what factors can affect proper adhesion. By doing your research, you can be sure that your white roof coating will last for many years to come.
