Roof coating is to roofing what skincare is to the body; they protect, enhance, and maintain the surfaces underneath. But while the metaphor is lighthearted, the consequences of neglecting either one can be serious. Every homeowner wants their home to stand the test of time, and a well-maintained roof is a critical component of that longevity.

In this helpful article, we will walk you through the intricate world of roof coatings, highlighting why they are indispensable for any homeowner keen on protecting their most valuable asset.
What Roof Coatings Are and Why You Need Them
Think of roof coating as a flexible, seamless layer that shields your roof from the elements. It’s not just a cosmetic upgrade, but a proactive measure that can extend the life of your roofing system. Coatings can be applied to a wide variety of roof types, including metal, single-ply, built-up, modified bitumen, and more. The choice to coat is often considered a more sustainable and cost-effective solution than a full roof replacement, especially when the existing roof is still structurally sound.
An additional benefit is the increase in energy efficiency. Lighter-colored coatings can reflect a significant portion of the sun’s UV rays, reducing the ‘heat island effect’ in urban areas and contributing to cooler temperatures inside your home during the warmer months.
Comparing the 3 Types of Roof Coatings
The coatings industry isn’t one-size-fits-all, and the viability of a coating for a specific roof largely depends on the material the roof is made of, the local climate, and the homeowner’s goals. Here’s a brief look at the main contenders:
1. Acrylic Coating
Water-based and quick to dry, acrylic coatings are often the go-to choice for their affordability, versatility, and ease of application. They’re an excellent option for single-ply and metal roofs and provide good UV protection.
2. Silicone Coating
Sometimes known as “cool roof coatings,” silicone is a more sophisticated polymer that excels in water resistance and breathability. They are UV stable, meaning they can handle direct sunlight without degradation, and thus, recommended for flat roofs with prolonged sun exposure.
3. Polyurethane Coating
Offering the most in terms of impact resistance and flexibility, polyurethanes often come in a two-part system, which must be carefully mixed on-site. They bond exceptionally well to the roof substrate, making them a durable solution for roofs with regular foot traffic or high mechanical stress.
Considerations Before Applying Roof Coating
Before you break out the brushes, there are several factors to consider to ensure the coating meets your expectations and requirements. Climate is a significant influence on the effectiveness of coatings. In areas with high UV exposure, you’ll want a UV-resistant coating like silicone. For regions that experience dramatic temperature fluctuations, the roof’s expansion and contraction should be accounted for with a flexible coating like Polyurethane.
Your roof’s current state is important as well. Coatings should not be used to solve underlying issues, like leaks or structural integrity problems. Ensure that your roof is clean, dry, and free of any existing coating that might interfere with the new application. Lastly, consider if the nature of the roof, be it flat or sloped, necessitates a different application method or material.
A DIY Guide to Applying Roof Coatings
Applying a roof coating is a project best suited for clear skies and mild temperatures. It is best to apply coatings during the warmer seasons as they require ambient temperatures to set correctly. The process involves thorough cleaning, repairing existing damage, and the appropriate application technique to ensure even coverage and longevity.
Here’s a step-by-step guide:
- Prepare the Roof: This step is about cleanliness and inspection. Remove any debris and clean the surface. Check for any surface conditions that require repair, such as cracks or corrosion.
- Choose and Mix the Coating: Depending on the type, you might need to mix two parts together. Always follow the manufacturer’s guidance for the correct mixing ratios and procedures.
- Apply the Coating: Using a sprayer, brush, or roller, apply the coating evenly to the roof’s surface, working in manageable sections. Ensure there are no bubbles or skips in the application.
- Allow to Cure: Most coatings will require several hours to cure, which may mean applying a second coat the following day or allowing it to set overnight.
- Inspect the Finished Product: After the coating has cured, inspect your roof to make sure the application was successful, and you have a uniform layer across your entire roof.
While it’s helpful to know how to apply roof coating, nothing beats the exceptional work of an experienced roofer.
The Bigger Picture: Roof Coatings and Home Stability
While a roof coating can do wonders for your energy bills and the immediate health of your roof, it’s just one part of a holistic approach to home maintenance. Regular roof inspections and timely repairs play crucial roles in ensuring the long-term stability of your home. Investing in a professional to periodically assess your roof can catch minor issues before they become costly problems.
