Acrylic vs Silicone Roof Coating

Roof CoatingIf you are responsible for a commercial roof, you have probably reflected on the inevitability that you will need to invest in a roof replacement at some point during the life of the building. However, before you take steps to replace your commercial roof, there may be a cost-effective, eco-friendly alternative that you overlooked.

A roof restoration system can protect your building from water damage, UV light, and various other hazards. The proper roof coating can also repair the damage that already exists. That being said, not all roof coatings provide the same protection for your commercial roof. What is the difference between acrylic roof coating and silicone coating? Which one is better to use on a commercial building?

What Is Roof Restoration?

Roof restoration is defined as the process of using a highly engineered coating that repairs damage and prevents future damage related to the elements and human contact. A roof restoration system allows the property managers to cut costs, reduce their environmental impact, and extend the longevity of the existing roof.

Types of Roof Coating Systems

If you want to prolong the life of your roof, you should consider a roof coating. Roof coatings were designed as a preventive measure to protect roofs from UV damage and leaks. They are also invaluable assets for repairing a commercial roof that has already sustained damage. Roof coating technology is available in silicone, acrylic, and aluminum.

What Is Acrylic Roof Coating?

Acrylic roof coating is a polymer specifically designed to coat roofs. Often called an “acrylic elastomeric” coating, this name refers to a “liquid applied, monolithic (seamless), fully adhered, elastomeric membrane that formed in situ on the roof.”

The acrylic coating is 5 to 10 times thicker than house paint and not as brittle. This type of coating is usually white in color. While an acrylic coating may look similar to paint, its benefits are very different.

Safe to Use, Easy to Apply

An acrylic roof coating is waterborne. It is applied as a liquid that hardens as it dries. This type of coating is considered easy to use because it does not require mixing with any other components. Acrylic roof coatings do not contain volatile organic compounds (VOC) that are harmful to the user and the environment.

Since these coatings are not red labeled, they are easy to transport through normal shipping avenues, which is an additional cost-saving.

Acrylic roof coatings are also no more toxic than a can of house paint, making them easy to store in the home, garage, or warehouse.

Elastomeric Membrane

If you are not familiar with the roofing industry, you may not be familiar with the term “elastomeric membrane.” What is it? In short, an elastomeric membrane is an aesthetic, durable, weather-resistant, and easy-to-maintain coating that is capable of stretching at least twice its length. Elastomeric membranes are used in commercial roofing as a liquid that is applied on top of an existing roofing system.

Not Paint

While elastomeric coatings are applied like paint, they are not the same thing. Acrylic elastomeric roof coating is the same viscosity as paint. It can be sprayed or brushed onto the commercial roof. However, paint does not require resistance to ponding water, flexibility at cold temperatures, or highly reflective properties. Paint also does not need to expand or shrink depending on the elements or foot traffic.

Acrylic elastomeric coatings require all of these features. They need to tolerate a variety of external stressors and ponding water contact for an extended period.

Benefits of Acrylic Roofing Systems

Benefits of Acrylic Roofing Systems - UV ProtectionAcrylic coatings offer protection from UV light; pounding water; inclement weather like snow or wind; and much more! In addition to shielding roofing materials from elements that can decrease the roof’s lifespan, acrylic coatings can also repair damage.

The ability to prevent and repair damage is a cost-effective tool for anyone who does not want to work a roof replacement into their budget. However, the cost savings do not stop there.

An acrylic coatings’ ability to reflect UV light means a commercial building using an acrylic roofing system will experience a reduction in energy costs. In turn, these energy savings help protect the environment.

Make it WHITE

Acrylic roof coatings are often white in color. This color provides two noticeable benefits for a commercial roof. First, it reduces the heat of the roof membrane. Also, white acrylic roof coatings extend the roof’s life and represent measurable energy savings by using UV blocking properties.

According to experts, another benefit of white acrylic roof coatings is that they can reflect as much as 85% of sunlight, which significantly reduces the temperature in the building, lowering air conditioning costs.

Dynamic Environments

A commercial roof is under constant pressure to adapt. Throughout the year, a roof contends with thermal expansion; the weight of snow and rain; wind uplifts; seismic expansion; and much more. A commercial roof must be able to hold up under these conditions in both high and low temperatures. The commercial roof must also be able to endure foot traffic from maintenance crews.

Caulks and Sealants

It is important to note that acrylic roof coatings are not the same as caulks or sealants. Elastomeric coatings tolerate expanding and contrasting pressures like caulk or sealant, but acrylic roof coatings are designed to withstand standing water. They are also impact-resistant and highly reflective. Caulk or sealant does not have any of these properties.

The Durable Choice

UV radiation is very harmful to a standard asphalt commercial roof. Over time, the asphalt absorbs the UV light causing the asphalt to deteriorate. Acrylic roof coating contains UV pigment blockers that reflect the degrading UV radiation. This process is done without causing harm to the environment, and it prolongs the life of the roof.

What Is Silicone Roof Coating?

Silicone is a high-performance polymer that aids in protecting a roof from UV damage, leaking, and other weathering effects. A silicone elastomeric coating is a single layer of silicone rolled or sprayed on a roof to repair blisters, cracks, or seams. Silicone coatings are most often applied to a flat or low-sloped roof, making it an ideal roof coating for residential properties and commercial buildings.

This type of roofing system is called a high solids (HS) protective layer. This layer does not increase the roof’s installation or inbuilt system. However, if you want to protect your roof from the elements, a silicone roof coating is the ideal choice.

What Is High Solid Silicone?

High solid silicone (HS) means that the coating has more silicone per gallon left over on the roof after the coating cures. The thickness of silicone is important to a contractor because it directly relates to a roof’s longevity. The thickness of the cured layer also determines what type of warranty can be applied to the roof.

High solid silicone is also the best choice for a single-layer application process. If your roofing restoration includes fees associated with materials, a high solid silicone means that a contractor will use fewer materials because they only use one layer.

What Is Low Solid Silicone?

Low solid or standard silicone (SS) has less silicone per gallon. A contractor often uses more layers to reach the desired effect. Standard silicone is prone to pinholes and mug cracks. These imperfections may seem like minor issues when the roof is newly restored, but they can lead to more significant problems as time passes.

Before you invest in a silicone roof restoration system, ask your contractor which style of solid they intend to use for your roof.

Benefits of Silicone Roof Coating

Pros & Cons to Silicone Roof CoatingThere are several cost-saving benefits to a silicone roof coating. The coating creates a smooth, waterproof layer that reflects UV light and resists even the most forceful monsoon. Silicone roof systems also hold up in both high and cold temperatures. Another benefit to using a roof coating is that there is zero construction involved in the process. The coasting is placed over the existing roof.

Drawbacks of Silicone Roof Coating Systems

Usually, when people talk about the benefits of a silicone roof coating, they are quick to mention that a silicone roof is extremely UV stable. However, that doesn’t mean that there are is not a downside to these coatings.

These roof coatings are very slick when they are wet. Roofs coated with a silicone roof will have to install a “walk pad” in high traffic areas for safety. They also attracted dirt and other particles meaning it will need to be regularly maintained to protect its reflective potency.

Acrylic Roof Coating vs Silicone Roof Coating

With so many similar features between the two roof coatings, a contractor or property manager may wonder which roof coating system is best for their commercial roof. As stated earlier, coating a roof is an ideal way to experience energy savings and prolong the life of your commercial roof. These savings can be achieved with both an acrylic and silicone roof coating system.

While silicone coatings are known to protect structures from ponding water better, acrylic coatings are valuable to use on “many types of substrates; modified bitumen, metal, built-up, single-ply and spray polyurethane foam.”

The best way to determine if your commercial structure needs an acrylic or silicone roofing system is to contact a licensed roofing professional. They can help you understand the needs of your building, and walk you through the pros and cons of the coating systems available.

Definitive 2021 Guide: Silicone Roof Coating

Definitive 2021 Guide: Silicone Roof Coating

Silicone Roof Coating.

Every homeowner has to replace or repair his/her roof eventually. The restoration process is a major expense, even with all the technological developments.

Roof Coating Manufacturers Association (RCMA) reports that roofing material is the third-largest contributor to waste in landfills. The waste is from torn off roofs.

The solution for this can be an elastomeric coating system like silicone roof coating.

It helps extend the life of the existing roofs without tearing off and replacing the roof of any building.

The most common commercial roofs can be:

  • Built-up Industry Roofing
  • Metal
  • Modified Bitumen
  • Single-ply
  • Spray Polyurethane Foam


Silicone Roof Coating

Silicone roof coating is a singular layer applied over existing roof systems. It can be sprayed or rolled to fill in the seams, cracks, and bubbling.

It forms an extra layer to protect the commercial roof from the natural elements.

How Does Silicone Roof Coating Work?

The silicone roof coatings form a waterproof, seamless, uniform membrane that repels ponding water. Once it hardens, it prevents the leaks without losing its adhesion to the roof.

Its reflective properties help maintain optimum temperature, save energy, deflect UV rays, and keep the commercial roof cooler despite the temperature.

Application Of Silicone Roof Coating

  • Infrared inspection is performed to identify saturated areas. These are then replaced.
  • The surface should be contaminant free. Power wash the roof to remove accumulated dirt.
  • Apply the primer to reinforce the seams of the membrane.
  • Perform miscellaneous repair to the roofing system.
  • Spray or apply the silicone with a roller over the entire commercial roofing surface.
  • At last, a representative from the manufacturer will inspect the installed coating for flaws.

Benefits of Silicone Roof Coatings

Silicone roof coating is highly effective of all coating systems:

  • High solids content
  • No need for primer
  • Better performance
  • Highly reflective
  • Resists ponding water
  • Impervious to moisture damage
  • Extend the life of your roofing systems
  • Save Energy

Constraints of Silicone Coatings

The negative effects of coating systems can include:

  • Easily accumulate dirt and lose reflectivity.
  • Other materials would not adhere.
  • Slippery when wet
  • Application can be challenging
  • Energy usage can increase when the film tears.

Drying Time for Silicone Roof Coating

Drying time for the installed silicone roof coatings depend on the weather conditions:

  • Dry Climate = Faster drying time
  • Dew and high humidity = Longer drying time

In general, the drying time would be anywhere from 8-24 hours. Hence, it is better to do it on days when the humidity is low.

How Long Does Silicone Coating Last on a Roof?

A silicone roof coating can last a long time. It can last nearly 15 years – 20 years as long as you perform annual maintenance without fail.

Ensure that you inspect after any major weather events.

Can You Spray Silicone Roof Coating?

Roof coatings can be sprayed or rolled out. When sprayed, it offers:

  • More uniform application
  • Smooth look
  • No ponding water
  • Quick application

The constraints of spraying include the unavailability of labor and the absence of training for the same.

Cleaning Silicone Roof Coating

Silicone roof coatings attract dirt and contaminants easier than other roof coatings. They should be cleaned periodically with a pressure wash for a good performance.

Your roofer should offer it as a part of the annual maintenance package.

If you need any information, contact your roofing contractor.

Cost of Silicone Roof Coatings

The cost of the coating systems depends on many factors like:

  • Products
  • Roofing areas
  • Special accommodation

You may be asked to pay around $0.50 to $3 per square foot.

Coming to the product, it costs roughly $10/gallon or less.

How Much Does it Cost to Repair A Silicone Roof?

Repairs are typically less than 25% of the roof.

The repairs cost approximately $0.70 – $1.40 per sq. foot. This includes both labor and materials.

Can I Use Silicone on a Roof to fix a leak?

Any leaking surface can be fixed via:

  • Silicone sealants: A time-consuming process but effective.
  • Silicone membrane: Applied over any existing roofing systems. Creates a waterproof layer that seals leaks.

Stop Leaks with Silicone Coating

Fixing the leaks and preventing future ones are by far the greatest advantages of silicone roof coatings. When applied, the products seal up all the existing leaks, provided the roofing systems are in good shape.

With regular maintenance, the coating system can help prevent future leaks that may happen. Since it is water-resistant, it also prevents ponding water.

Silicone Caulk for Shingle Repairs

Silicone caulk is nothing but a roof sealant product that can be used via a caulk gun. Use it to fix leaks and bent shingles.

  • Place a bead of caulk below the bent shingle. Bend the shingle back into the right place and weigh it down.
  • Fill the cracks with the caulk from underneath and press the shingle back to fill the crack.
  • Seal the separation between the shingles and flashing with the silicone caulk.

Recoating with Silicone

Silicone can adhere to itself and other surfaces without a need for primer. Hence recoating should not be an issue. As long as it doesn’t need any major repair, you can recoat it as you would do with new roofing.

Reliable Sealant for Flat Roof Surface

Silicone is probably the most suited sealant for flat roofs. The benefits of silicone products range from:

  • Leak protection
  • Aesthetic appeal
  • Highly Sustainable
  • Doesn’t absorb moisture

Best Flat Roof Coating for Commercial Building

A 100% single component elastomeric roof coatings like silicone coatings work for commercial roofing. The new series of silicone products are not water-based and also solvent-free. Hence contain 95% solids, most of which stay on the roof.

You can also use urethane-silicone, which combines both worlds in adherence, UV protection, and moisture resistance.

Recoat Your Flat Roof

Though your silicone should last long, it is advised to recoat it once every 5 years for better performance. The frequency also depends on your local climate.

Recoat Polyurethane Foam Roofing with Silicone

Foam materials need a silicone topcoat to protect them from the sun. Even then, it should be renewed every few years.

It can be sprayed or rolled on the existing foam roof. The solution doesn’t require the existing one to be torn off or replaced.

Other Common Types of Elastomeric Roof Coating

Depending on aesthetics, roof type, weather, etc., the industry roof coatings can be:

  • Acrylic Roof Coatings
  • Asphalt Emulsion
  • Butyl Rubber
  • Urethane Roof Coatings

Silicone Vs. Acrylic

Silicon sealing material performs better than its counterpart and also goes on easily.

Many acrylic sealants on the other hand can be painted which is not the case with silicone. It also has much lesser VOC levels than others.

Best Roof Coating

There is no particular best coating system. The liquid-applied system depends on the building you are trying to restore.

  • Sloping Roof: Acrylic coating
  • Flat Roof: Solvent-based material


The silicone coating is much preferred among other roof coatings due to its ability to withstand all climatic conditions. It is applied via a spray or roll on.

While the roll-on takes time, it doesn’t need any technical expertise. But the spray needs experience before it goes on as smoothly.

Silicone coating adheres on all roofs without any issue. It is also highly efficient and also moisture resistant. It is also waterproof and prevents water damage. Hence best suited for flat roofs.

Annual maintenance and recoating every 5 years help the installed coating to last longer.
