Roof coatings are products that are designed to protect and conserve the structural stability of your underlying roofing material. Two of the most common types of roof coatings are made out of acrylic and polyurethane. Though they perform the same function, the material differences between these two types of roof coatings provide a distinctive set of benefits and drawbacks to your roof. Understanding the differences between the set of features that acrylic and polyurethane roof coatings provide can help you choose the one that best suits your roof's needs.

Acrylic Roof Coatings

Acrylic roof coatings are the most common type of roof coating on the market, mainly because of their high affordability. Acrylic roof coatings are applied to roofs in order to increase the reflective ability of the actual roofing material. By reflecting increased amounts of sunlight, acrylic roof coatings can reduce your long term energy bills, by reducing your heating bills in the summer months. Additionally, by reflecting the UV rays from the sun, acrylic roof coatings are able to extend the lifespan of your roof by reducing the amount of UV radiation that your roofing material is exposed to.

However, though acrylic roof coatings are able to withstand a great deal of sunlight, they are extremely susceptible to physical damage. This means that in coastal areas, or in areas that receive a great deal of hail or precipitation, acrylic roof coatings can wear away extremely quickly, increasing your long term costs and maintenance. 

Polyurethane Roof Coatings

Polyurethane roof coatings are a less common roofing coating option that are more physically durable than acrylic roof coatings. They can withstand a great deal of physical trauma, and even stand up to extended water exposure, without degrading over time. This makes them a much better fit for areas that receive more extensive weather exposure, and will last much longer than acrylic roof coatings, reducing your long run costs.

However, polyurethane roof coatings are not designed to stand up to extended periods of UV radiation, and will yellow or discolor over time. This means that in extremely sunny areas, polyurethane roof coatings may ruin the aesthetic of your home, and may need to be repaired or replaced. Additionally, it should be noted that polyurethane roof coatings are more expensive to purchase and have installed than acrylic roof coatings, which makes them the less ideal option for homeowners who are operating under a tight budget.
