Understanding Roof Coating Systems: How They Work and Why They're Used


Roof coating systems have become an increasingly common solution for extending the lifespan of both residential and commercial roofs. In climates like San Diego, where sun exposure, heat, and occasional rain can wear down roofing materials over time, roof coatings offer a practical way to restore and protect existing roofing without needing a full replacement.

What Is a Roof Coating System?

A roof coating system is a fluid-applied layer of protective material that’s installed directly on top of an existing roof surface. It forms a seamless, waterproof membrane that helps improve the performance of the original roofing system.

These coatings are typically used on low-slope or flat roofs and are made to withstand UV rays, ponding water, temperature changes, and general weathering. Once cured, the coating acts as a barrier that resists moisture and reflects heat — both of which are especially beneficial in Southern California’s climate.

Types of Roof Coating Materials

Several different types of coatings are used, depending on the type of roof and the performance goals:

Silicone Coatings – Known for their durability and resistance to ponding water. Commonly used in areas where water tends to collect.

Acrylic Coatings – Popular for their reflectivity and cost-effectiveness. Best suited for dry climates.

Polyurethane Coatings – Durable and abrasion-resistant, often used in high-traffic areas or industrial settings.

Asphalt-Based Coatings – Typically used on modified bitumen and built-up roofs (BUR).

Some coatings are also labeled as “cool roof” products due to their high reflectivity, which can help reduce heat absorption on the roof’s surface.

When Are Roof Coatings Used?

Roof coatings are generally used in situations where the existing roof is still in good structural condition but may be nearing the end of its service life. Common reasons property owners or facility managers opt for coatings include:

Minor surface degradation without major structural damage

Small cracks or early-stage leaks

Energy efficiency improvements

Extending the life of an aging roof

Preventing moisture intrusion in flat roof areas

They are also sometimes used after roof repairs to reinforce and protect vulnerable areas.

Advantages of Roof Coatings

There are several functional advantages to using roof coating systems:

Leak Prevention – Coatings create a seamless surface that helps prevent leaks from cracks, seams, or penetrations.

UV Protection – Coatings reflect harmful ultraviolet rays, which slows the aging of the roof underneath.

Energy Efficiency – Reflective coatings reduce roof surface temperatures, which can ease the load on HVAC systems in hot weather.

Reduced Tear-Off Waste – Because coatings are applied over the existing roof, there is often less waste generated than during a full replacement.

Minimal Disruption – Installation is usually faster and less disruptive than a full reroof, which can be important for commercial properties.

Common Roofing Systems and Considerations

Limitations and Considerations


While roof coatings provide many benefits, they aren’t suitable for every situation. If a roof has major structural damage, large leaks, or significant deterioration, coating may not be enough. In those cases, partial or full replacement may be required.

Additionally, not all roofing materials are compatible with every type of coating, so it’s important to assess the existing roof and choose the appropriate product.

Common Roofing Systems That Use Coatings

Roof coating systems are commonly applied over:

Modified bitumen roofs

Built-up roofs (BUR)EPDM and TPO single-ply roofs

Metal roofing systems

Spray polyurethane foam (SPF)

Each system requires specific surface preparation, and in some cases, a primer may be needed to ensure proper adhesion.

Summary

Roof coating systems offer a practical way to maintain and protect low-slope or flat roofing systems, especially in sunny regions like San Diego. While not a replacement for every roofing issue, coatings can significantly extend the life of an existing roof, improve reflectivity, and provide added waterproofing in the right conditions.

Regular inspections and maintenance can help determine when a coating is appropriate and which type is best suited for a specific building or roofing material.

I recently had an urgent roofing issue brought to my attention by the heavy rain we recently experienced. Near our chimney there was water somehow leaking inside and reaching the drywall. We called Titan Roofing and were blown away by their prompt response and professionalism.

Their team arrived on time and worked efficiently to remove all the roof tiles in the area, strip the underlayment, and found the wood rot issues with the plywood. They then replaced the plywood, used a sealer, replaced the underlayment, and added the roof tiles back in place. My wife is a bit picky when it comes to the home aesthetics, but Titan Roofing even made sure we were completely satisfied before they left.

The team was knowledgeable, courteous, and provided a fair and transparent estimate. I was also impressed with the care they took to protect my property and clean up debris after the job was done. I highly recommended Titan Roofing for any roofing needs, big or small.

If you are reading this, that means you are looking for a great roofer! Titan Roofing owned by Andrez Lopez is incredible! We've done quite a bit of remodeling at our home and contractors were all over the map with bids and credibility.

I researched six large and small companies from Angis list and Home advisor. One company came out and said "I'll look at your roof from a satellite view and give you bid in a few days! Huh?!

Andrez, the owner of Titan Roofing was the ONLY owner who walked up ON THE ROOF himself, told us what was needed, and then said that we needed to replace our bathroom vents and fireplace spark arrestors! And that was in the first 20 minutes! We paid him to come back and replace those items!

We cannot be happier! I'm kind of a hard ass, but when I realized how great Andrez' Titan Roofing was, we hired them. They are far above the other roofers we interviewed! His bid was $5000 less that three other bids, and get this: He also replaced all of the bad facia, and installed new rain gutters!

So, what will you get with Titan Roofing?

We have had Titan Roofing complete two roofs for our family. Andres has a wonderful attitude and a commitment to doing a great job. He and his crew reroofed my daughter's two story peak roof in 3 days in the very hot September weather.

They replaced a 30 year old roof with new cooler materials and added flashings and drain pipes.

In March 2022, he quickly responded to my emergency situation of a leaking roof by doing a temporary spot repair, getting materials ordered, and starting reroofing only 2 days later. Andres and his crew worked overtime and on the weekend to try to finish the roof before the next rainstorm. He even sent a worker up on my roof with a flashlight on Sunday night to make sure drain bolts were tightened and everything was okay before predicted rain. Then the next morning he came extra early to finish the job and check all the work ahead of the rainstorm. Not only did they do job quickly but older torch down roof was replaced with insulation, new cooler TPO material, better drain system and additional attic vents.
