One of the most common questions building owners ask is what silicone roof coating products are the best?

Silicone roof coatings have become extremely popular across Southern California because they allow property owners to extend the life of an existing roof without paying for a full replacement.

In areas like City of Industry, where large commercial warehouses and industrial buildings are common, silicone coatings are frequently used to stop leaks and restore aging roofs.

At All & One Construction & Restoration, we’ve installed silicone roof coatings on commercial buildings throughout the Industry Hills area, the Valley Boulevard warehouse corridor, Turnbull Canyon industrial properties, and the La Puente industrial district.

Based on our experience installing these systems, the best silicone roof coating products we commonly recommend include:

• Gaco Silicone Roof Coating
• Sherwin Williams Silicone Roof Coating
• GE Silicone Roof Coating

Each one can seal and waterproof a roof effectively, but some perform better depending on the condition of the roof and the client’s budget.

Why Silicone Roof Coatings Are Popular in Southern California

Silicone coatings are especially useful in California because they help buildings meet Title 24 cool roof energy requirements.

These coatings reflect sunlight and reduce roof temperatures, which helps lower cooling costs for commercial buildings.

According to the Cool Roof Rating Council (CRRC), reflective roof systems can significantly reduce heat absorption and improve building energy efficiency.

For large commercial roofs in City of Industry’s industrial zones, silicone coatings are one of the most cost-effective restoration methods available.

Best Silicone Roof Coating Products Contractors Recommend

Gaco Silicone Roof Coating

When clients ask us what the best silicone roof coating products are, Gaco is usually our top recommendation.

Gaco silicone tends to be thicker and more durable than many other coatings on the market. This makes it ideal for roofs that are aging but still structurally sound.

From our experience installing coatings across the Industry Hills and Hacienda Heights industrial areas, Gaco offers several advantages:

• Thicker coating application
• Excellent waterproofing
• Strong UV resistance
• Long lifespan

The only downside is that Gaco is typically the most expensive option.

However, if the roof is in rough condition but the substrate is still intact, Gaco is often worth the investment because it can extend the life of the roof significantly.

Sherwin Williams Silicone Roof Coating

Sherwin Williams is another product we install regularly, especially for commercial buildings looking for strong cool roof performance.

Sherwin Williams coatings have very high reflectivity ratings, which makes them a great option for buildings that need to meet Title 24 energy requirements.

In many commercial properties along the Valley Boulevard industrial corridor, we’ve used Sherwin Williams coatings to restore torch-down roofs that had developed small leaks.

Benefits include:

• High solar reflectance
• Strong waterproofing
• Title 24 compliance
• Long-term durability

GE Silicone Roof Coating

For property owners who want a more budget-friendly silicone coating, GE coatings can be a solid choice.

While GE coatings accomplish the same goal of sealing and protecting the roof, they are typically more affordable than premium coatings like Gaco.

In commercial properties near the La Puente industrial district and Turnbull Canyon business area, GE coatings are often used when the roof is still in good condition but the owner wants to control project costs.

Benefits include:

• Reliable waterproofing
• Cool roof compliance
• Lower cost installation
• Good durability

Real Silicone Roof Coating Case Study in City of Industry

A good example of how silicone coatings solve real roofing problems was a commercial building project in the City of Industry area.

The building had approximately 20,000 square feet of torch-down roofing.

Over time, the roof developed multiple small leaks, which is very common for older modified bitumen roofing systems.

However, during our inspection we found that the roof substrate was still intact, which meant the building owner did not need a full roof replacement.

Instead, we applied a Sherwin Williams silicone coating system.

The results were immediate:

• Leaks were sealed
• Roof life was extended
• The building gained a reflective cool roof surface

Instead of replacing the roof, the owner saved a significant amount of money while still fixing the problem.

When a Roof Is a Good Candidate for Silicone Coating

Not every roof should receive a silicone coating, so a proper inspection is critical.

Based on our experience working on commercial roofs throughout City of Industry and surrounding industrial neighborhoods, we typically look for several key factors.

The Roof Structure Is Still Sound

If the roof deck and insulation are still intact, a silicone coating can restore the waterproofing layer without needing full replacement.

The Roof Has Small Leaks

Silicone coatings are excellent for sealing minor leaks and cracks, especially on aging torch-down roofs.

The Roof Is Flat or Low Slope

Most silicone coatings perform best on flat or low-slope commercial roofs.

Steeper roofs can sometimes be coated as well, but this is typically limited to metal roofing systems.

Final Thoughts on the Best Silicone Roof Coating Products

So what silicone roof coating products are the best?

From our experience installing coatings on commercial roofs across the City of Industry area, the answer depends on the condition of the roof and the building owner’s budget.

• Gaco – best long-term durability and thicker application
• Sherwin Williams – excellent reflectivity and strong cool roof performance
• GE – reliable and more budget-friendly option

All three coatings can successfully seal and restore a roof when installed correctly.

If your roof is starting to leak but the structure is still intact, silicone coating may allow you to avoid a full roof replacement and extend the life of your roof for years.
