What Does Roof Coating Do?

Roof Coatings Offer Protective Benefits to Commercial Roofs!

Roof coatings offer a variety of protective benefits to your commercial roof!

For many homes and businesses, a roof coating is a great cost-effective option in remedying the risk of minor damages or in protecting your roof from potential damages and repairs. Instead of being subjected to the high costs of a complete roof replacement or removal, roof coatings to an existing weathered roof can be as much as $0.50-$3 less in costs per square foot! Roof coatings are a great alternative as they can prevent leaks, offer protection from UV rays as well as a wide range of protection from other negative impacts depending on which type of coating you choose to employ! After taking into consideration some points and information regarding roof coatings, you’ll see if roof coating is any good for your commercial roof!

Firstly, it’s important to know when to apply a roof coating, an improper application may negate any benefits you were likely to get if applied incorrectly. Make sure to apply roof coatings before any rainfall, if the coating has not fully dried than it can be affected with surface defects or may even wash off. Heavy dew can also be a factor in improper drying. Therefore, it may be best to consider roof coatings during warmer and dry seasons. In cold weather, for example, dry and curing time is extended and can even lengthen the dry time to the point where rainfall is an eventuality. Additionally, freezing or frost can affect the adhesive properties of the roof coating so it’s important to read the instructions certain manufacturers have placed on their products regarding proper conditions of weather and temperature upon roof coating applications.

Don't Apply Roof Coatings Too Thick or Thin!

It’s essential that roof coatings be applied in the right thickness to ensure proper protective performance!

How much roof coating do I need?

Another condition to keep note of regarding roof coating application is how thickly or thin of a coating your roof requires. A roof coating that is too thick or heavy can cause bubbles, wrinkles, and blisters in the film. That is because the coating beneath each additional one hasn’t had the time to dry before the next one was layered onto it which traps the chemicals and water inside. As a counterpoint, when a roof coating is too thin than the water and solvents will evaporate when the coat dries and the roof won’t have the necessary strength it requires for roof protection. To ensure proper roof coating thickness, it is recommended to incorporate supplementary wet mils in order to compensate for initial mil evaporations during set up.

How much does roof coating cost?

Costs of roof coating vary depending on your roof’s slope, roofing material, the type of coating that is applied as well as the brand of the roof coating. All in all, prices can range from as little as 15 cents per square foot to $3 per square foot. If you are coating an already existing roof membrane, then one coat could be enough and thereby lower costs an average of $0.50-$1.50 per square foot!

Does roof coating stop leaks?

Roof coatings can stop and prevent minor leaks on your commercial roof. However, it is recommended to still address the issue of damages prior to application. Whether they are minor or more severe, damage repair and seals should be allowed to set in or dry before a new roof coating.

Elastomeric Roof Coatings Can Go On Any Roof Type!

Elastomeric roof coatings can be applied to any type of roofing material!

What is an elastomeric roof coating?

An elastomeric roof coating is a special type of roof coating that can be used to repair any type of roof leak and can be applied to any type of roofing material! It’s a long lasting product that is usually made of polymeric products, that are water soluble and water resistant when they dry, along with white pigments such as titanium dioxide which creates a reflexive and opaque final product. What’s special about elastomeric roof coatings are that they can be used any time of the year since they’re able to stretch and contract in adjustment to temperature changes. (This ability also contributes to resisting foot traffic.) They provide a seamless and even look to the roof and are also resistant to mildew, fungi and other common materials that can damage roofs over time. They don’t produce VOCs (volatile organic compound) and are nontoxic and have heat reflexive and anti-aging abilities that can reflect sun rays which can damage the roof in time. This ability ultimately cools down your building which in turn lowers cooling costs (Electric Furnace Service.) Depending on the roof type it can also offer UV protection and have great ozone.

Can elastomeric roof coating be painted?

Typically elastomeric roof coatings are difficult to paint over. That is because they are very slick when dry and don’t accept new paint as easily as oil or latex painted surfaces. They require specific protocol if you wish to paint over these surfaces.

What is the best elastomeric roof coating?

Commercial Roof Coatings Are Best With a Qualified Professional!

The four main types of elastomeric roof coatings are acrylic, butyl, silicone, and polyurethane. Depending on the type of roofing material and roof slope you have, there are different recommendations of the type elastomeric roof coating you should use. Acrylic is best for sloped roofs and is more environmentally friendly and longer lasting than butyl. Butyl is best used for flat or low sloping roofs. They are great as vapor barriers and have exceptional water pounding resistance. Silicone is best used for polyurethane foam roofs and is very effective at repairing weathering. Finally, polyurethane is best used for EPDM rubber roofs yet can also be used on single ply or modified bitumen roods. They are a great option as they don’t require a high PH rinse.

Ultimately, no matter the type or slope of roof you may have, there is a roof coating out there for your commercial roof coatings and repairs.
