Roof Coatings

Roofs can be constructed from an amazingly broad variety of bulk materials, including metals, plastics, rubbers, fibers, glass, wood, rocks, ceramics and the list goes on. But as the world is progressing, many revolutions in the construction field have been observed as well. New technologies have been evolving to make the human living more secure and safe. It’s the need of time that the roofing contractors must also be familiar with roof coating. Roof coating is a monolithic, fully adhered, fluid applied over the roofs and has elastic properties that allows it to stretch and return to their original shape without damage.

Finding just a roof coating is not sufficient; the requirement is to find a good coating for your roof that will maximally protect your roof from the weakening factors whether they are the UV rays or extreme weather conditions. There are many types of roof coatings available and there are pros and cons of each of these types. Which type of coating you choose depends on your selection criterion that what is your primary purpose of using the roof coating, whether it is to provide maximum solar protection or roof leak repair etc.


Some of the most common roof coating product categories are:

• asphalt cutbacks and emulsions
• polymer-modified acrylic elastomers and polyureas
• silicones
• high-performance urethanes
• SPF

It is important to select the coating to be compatible with the roof, and the roofing contractor must follow the manufacturer’s preparation and application instructions exactly. If these guidelines are properly followed, the end results will definitely be fruitful.

Functions of Roof Coatings

Roof coating is a roofing membrane made of either elastomers (elastomeric roof coatings) or fully adhered monolithic fluid. The roof coating is the outermost layer of the entire roofing system, as it is 20-40 dry mils thick. Therefore, it is the most exposed layer of protection for a roof, and receives the strongest beating from the sun and UV rays, rain and hail, wind, debris, and all of Mother Nature’s most damaging effects.
Roof coatings work in several ways:
  1. Roof coating reflect the sun and weather, thereby reducing cooling costs and the need for extensive cooling systems.
  2. Roof coating’s elastic properties allow it to stretch and shrink without lasting damage (known as elastomeric roof coating).
  3. Roof coatings act as an additional form of waterproofing, while at the same time allowing trapped moisture to escape.
  4. Roof coatings can be applied in a range of colors to suit all roofing styles and designs.
  5. Some roof coatings are even designed to prevent the growth of moss and algae, and are environmentally friendly.
  6. Other roof coatings are capable of preventing corrosion, and are flame-resistant.
