What is elastomeric roof coating used for?

Elastomeric roof coatings can be applied over new roofs to provide an extra layer of weatherproofing, or they can be applied to older roofs to seal leaks, reinforce the roof’s integrity, and extend lifecycle expectancy.

Is elastomeric roof coating good?

A quick recap of what an elastomeric roof coating is Usually, these roofs are in good working order with minimal leaks, and their warranty is about to expire. A building owner installs an elastomeric roof coating for a few reasons: it’s more cost-effective than a complete tear-off.

What is an elastomeric coating?

Elastomeric coatings are protective barriers that are applied on interior and exterior walls as wall paints. Elastomeric coatings can be water-based coatings and paints or acrylic latex paints. They are applied as a thick coat on concrete structures.

Which is better silicone or elastomeric?

Longevity. Many factors can affect the longevity of an elastomeric coating, but mil for mil, silicones last longer than acrylics. This is mostly due to the inherently superior UV and moisture resistance of silicone materials.

Which roof coating is best?

Silicone roof coatings are the preferred choice when it comes to UV protection and resistance to ponding water. They erode much slower than other coatings without becoming brittle or hard. Modern silicone formulations have a high-solids content that typically exceeds 90 percent.

How is elastomeric applied?

An elastomeric coating is a coating that’s capable of being stretched at least twice its original length (100\% elongation) and recovering to its original dimensions. Elastomerics are used in commercial roofing as a liquid that gets applied on top of an existing roofing systems to form a membrane.

Are all elastomeric roof coatings the same?

Not all roof coatings are created equal! Both are good products, but as with many products, acrylic and silicone each have good and bad qualities. This means elastomeric can stretch about 300\% more than a standard acrylic. If the name elastomeric sounds like the term ‘elastic’, now you know why!

What are the different types of roof coatings?

The most common types of roof coatings are acrylic, asphalt, polyurethane, and silicone. Acrylic water-based coatings are suitable for high UV environments where a reflective roof is desired. They can be colored, but generally are sold in white, tan, and grey.

Is elastomeric roof coating waterproof?

Most kinds of elastomeric roof coatings are deemed as possessing both weatherproof and waterproof properties. A roof sealer of the elastomeric variety is typically a polymeric product. This means that they create a seal when they are applied to a roof.

Can you put elastomeric roof coating over shingles?

The only way to solve that issue with a coating is to apply an elastomeric type coating to encapsulate the shingles. When needed you simply apply another single coat that will bond to the original coating.

Are roof coatings any good?

Roof coatings do not prevent heat loss via the roof (a popular claim). They do not offer any long-term protection against moss and they can look awful when the paint/coating starts to peel off. One claim often touted by roof coating companies is that a roof coating will increase the value of the property.
