Roof Coating Education
Acrylic roof coatings
Strengths: Acrylic coatings can be beneficial to you in many ways. They are extremely reflective and provide great resistance to UV rays. It’s a great choice for a wide range of different roofs, and it is also generally an affordable option.
Weaknesses: Acrylic coatings do have some potential weaknesses. For instance, they may wear down in response to weathering, and they should not be used in situations where there may be ponding water. They should always be applied at 50°F or above.
Polyurethane roof coatings
Strengths: Polyurethane roof coatings stand up well to traffic and impacts of all types, and they are also highly resistant to ponding water. They tend to stay clean, so they are a good option if you are looking for a cool roof.
Weaknesses: On the other hand, polyurethane roof coatings tend to have a strong odor that other coatings may not have. They are generally more costly than acrylic coatings.
Silicone roof coatings
Strengths: Silicone coatings stand up very well to weathering, water, and other common hazards. They are moisture-cured, and they can be used in humid climates.
Weaknesses: These coatings will become less reflective over time. They are also much less resistant to tearing than some other coatings. If you decide to recoat your roof, you will need to remove or recoat your silicone coating.
