The more protection a roof has, the less often it will need to be repaired or replaced. If you’re a roofing contractor, then you have a variety of roof coatings to choose from. Polyurethane is one of the most powerful coatings, so it’s suitable for many different situations. If you select the right coating for a roof, you’ll help to ensure that it gets the strong, lasting protection it needs. Here’s what you need to know about these types of roof coatings.
What is polyurethane?
Polyurethane is a type of plastic which comes in both rigid and flexible forms. It’s also highly environmentally friendly. Thus, it’s a good roof coating for homeowners and business owners who want to reduce their carbon footprint.
What are the different types of polyurethane?
There are two primary types of polyurethane: aliphatic and aromatic. Aliphatic offers a greater degree of UV protection. Thus, it’s preferred for areas that see a lot of sun. Aromatic is generally used as a base coat, while aliphatic is usually used as a top coat because it retains color for a long time. However, both types offer the same high value in terms of protecting roofs.
What are the benefits of using polyurethane roof coatings?
Polyurethane roof coatings can provide any building with reliable performance and excellent value. Unlike some roof coatings, they are versatile enough to work well for nearly any roof, whether flat or sloped. They also work well on most roof surfaces, whether smooth or textured. They are adhesive to most surfaces, including metal, concrete, and plastic. Many roofing contractors use them to provide a base coat for silicone roof coatings, so they’ve become especially useful.
How elastic are polyurethane roof coatings?
Roof coatings should be strong enough to last but also elastic enough to adjust to changes in the shape of the roof. Polyurethane roof coatings are highly flexible, so they can stretch to conform as the roof expands or contracts in response to outside temperatures. If a client is concerned about abrupt changes in the weather harming their roof, then this type of roof coating may be the best possible choice for them.
How durable are polyurethane roof coatings?
One of the main advantages of polyurethane roof coatings is their durability. Compared to other roof coatings, these coatings are more likely to hold up well against impacts. They also hold their shape well over time. Thus, these coatings are good for clients who may be concerned about pooling water damaging their roofs.
How UV-resistant are polyurethane roof coatings?
Sun damage is a concern for many homeowners, and rightly so. UV radiation can easily damage a roof and lead to the need for repairs. In some cases, the damage may even require roof replacement. A polyurethane roof coating with an aromatic base coat and an aliphatic top coat can provide a high level of UV protection, thus ensuring that the roof stays safe from damage. This will also help to keep the inside of the building cool.
