Why Roof Coating Is Essential
Roof coatings play a vital role in safeguarding your building against the elements. As commercial roofs are constantly exposed to the sun, rain, wind, and extreme temperatures, roof coatings act as a barrier that reduces wear and tear. Additionally, roof coatings enhance the structural integrity of your roof, offering resistance to UV rays, water damage, and physical damage from storms or falling debris. In regions with extreme weather conditions, having a reliable roof coating is more critical than ever.
For example, silicone coatings are excellent for areas that experience heavy rainfall because they provide superior resistance to ponding water. On the other hand, elastomeric coatings are ideal in areas with significant temperature fluctuations due to their flexibility.

Types of Roof Coatings for Commercial Buildings
Choosing the right roof coating depends on various factors including the climate, roof type, and your building’s budget. Here’s a breakdown of the most common types of roof coatings for commercial buildings:
1. Acrylic Roof Coatings: Reflective and Budget-Friendly
Acrylic coatings are one of the most popular and cost-effective options for commercial roofs. These coatings are highly reflective, which helps reduce cooling costs by reflecting sunlight away from the building. They are especially beneficial for buildings located in warm, sunny climates, where keeping the building cool is a priority.
- Best For:
- Metal roofs
- Single-ply roofs (e.g., TPO, EPDM)
- Spray polyurethane foam (SPF) roofs
- Benefits:
- UV-resistant, preventing damage from the sun.
- Flexible, allowing for expansion and contraction with temperature changes.
- Budget-friendly and one of the more affordable roof coating options.
- Considerations:
- Acrylic coatings are not the best choice for areas that experience heavy rainfall or standing water, as moisture exposure can degrade the coating over time.
- Example Products:
- Generic Acrylic Roof Coating: Available at most hardware or roofing supply stores, these coatings are typically sold in large quantities and can be used on a variety of roofing materials.
- Reflective White Acrylic Coating: This type of acrylic coating is a common choice for its energy efficiency and reflective properties.
2. Silicone Roof Coatings: Ideal for Wet Conditions
Silicone coatings are an excellent choice for roofs that are exposed to frequent or standing water. Their exceptional waterproofing capabilities make them ideal for flat roofs or roofs in areas with high humidity or heavy rainfall. Silicone coatings also offer impressive UV stability and resist cracking or chalking under sun exposure.
- Best For:
- Flat or low-slope roofs
- Roofs in humid or rainy climates
- Benefits:
- Excellent waterproofing, ideal for managing ponding water.
- Highly UV-stable, which prevents deterioration from sunlight.
- Requires less maintenance than other coatings due to their ability to shed dirt and debris.
- Considerations:
- Silicone coatings tend to attract dirt, which may reduce their reflective properties over time. Periodic cleaning is required to maintain their effectiveness.
- Example Products:
- Generic Silicone Roof Coating: Available from a variety of suppliers, these coatings are known for their superior waterproofing and durability. They are typically available in white or clear versions to maintain reflective properties.
- Polymeric Silicone Coating: A common choice for commercial buildings, providing excellent ponding water resistance and UV protection.
3. Polyurethane Roof Coatings: Durable and Impact-Resistant
Polyurethane coatings are well-regarded for their toughness and impact resistance. These coatings are ideal for commercial buildings with high-traffic areas or those exposed to physical damage, such as roofs with HVAC equipment or areas where foot traffic is frequent. They are highly durable and can withstand the wear and tear of everyday use.
- Best For:
- Modified bitumen roofs
- Single-ply roofs
- Concrete roofs
- High-traffic areas
- Benefits:
- Impact-resistant, making them perfect for roofs subject to physical damage.
- Bond well to a variety of roofing materials.
- Can be combined with reflective topcoats to provide enhanced UV protection.
- Considerations:
- Polyurethane coatings generally require a topcoat for UV protection, which adds an additional layer to the application process.
- Example Products:
- Generic Polyurethane Roof Coating: These coatings are widely available in hardware stores and come in both clear and tinted formulas to suit various roof types.
- Durable Urethane Coating: A highly durable product often used in industrial settings to ensure long-lasting roof protection.
Common Questions About Roof Coatings
1. How long does a roof coating last?
Roof coatings typically last between 10 and 20 years, depending on factors such as the coating type, climate conditions, and how well the roof is maintained. Regular inspections and maintenance can help extend the life of your roof coating.
2. Can roof coatings help reduce energy costs?
Yes! Roof coatings like acrylic and elastomeric coatings are highly reflective, helping to reduce heat absorption and lower cooling costs during the warmer months. Reflective coatings are especially beneficial for commercial buildings in sunny climates, where cooling energy bills can be high.
3. Do I need to recoat my roof over time?
Yes, roof coatings may need to be reapplied periodically to maintain optimal performance. The frequency of recoating depends on the type of coating used and the climate in which the building is located. For example, acrylic coatings in regions with heavy rainfall may need reapplication every 10–15 years.
4. Are roof coatings only for flat roofs?
No, roof coatings can be applied to a variety of roof types, including sloped and metal roofs. While silicone coatings are often used on flat roofs due to their waterproofing properties, other coatings like acrylic and polyurethane can be used on sloped roofs as well.
5. How long does it take to apply a roof coating?
The time it takes to apply a roof coating depends on the roof size, the type of coating, and the weather conditions. Generally, coatings dry within a day or two, but it’s a good idea to allow a few days for proper application and curing to ensure optimal results.
Quick Facts and Tips for Choosing a Roof Coating
- Consider Climate: In regions with heavy rainfall or high humidity, silicone coatings are ideal for their waterproofing qualities. For dry, sunny climates, opt for acrylic or elastomeric coatings for their reflective benefits.
- Match Roof Material: Not all coatings work well with all roof types. For example, asphalt-based coatings bond better to metal roofs, while acrylic works well with single-ply materials. Always check for compatibility with your roof’s material.
- Plan for Maintenance: Some coatings, such as silicone, require regular cleaning to prevent dirt buildup. Maintaining the reflectivity of the coating can help improve energy efficiency and prolong its lifespan.
- Set a Budget: Acrylic coatings are generally the most budget-friendly option, while silicone and polyurethane coatings offer enhanced durability and protection but can come at a higher cost.
- Consult a Professional: It’s essential to consult with a professional roofer, such as those at Acker Roofing, who can assess your roof’s condition and recommend the best coating for your needs. A professional roofer will also ensure the proper application and maintenance of the coating to ensure maximum effectiveness.
