Roof Coating

WHICH FLAT ROOF COATING WILL WORK BEST FOR YOUR COMMERCIAL ROOF SYSTEM

The threat of roof damage and roof leaks are a major concerns for property managers, facility managers, and consultants. A roof coating is a monolithic, fully adhered, fluid applied roofing membrane. It has elastic properties that allows it to stretch and return to their original shape without damage. These roof coatings can help protect and prolong the life of your roofing system. Roof coatings can help lower costs by avoiding full roof replacements and more intensive roof repair. With advancements in technology, the options for roof coatings have greatly increased. Some of the most popular roof coating options include:

Acrylic- Acrylic coatings are water based materials. Acrylic coatings are low risk because of their low toxicity and flammability. Unlike other options, acrylic roof coatings come in a multitude of colors to match the color scheme of your building. Temperature is a limiting factor in the application of acrylic roof coatings. If it is too cold it will freeze. If it is too hot it will not set properly. The right temperture is required for the coating layers to properly cure. If ponding water is present for more than 48 hours, it is possible for the coating to lose adhesion and return to its liquid state. .

Silicone- Silicone roof coatings have been around for a long time. They are used on a variety of roof types from single-ply to metal roof systems. It is most commonly used on spray polyurethane foam roofs because of the materials permeability. Silicone roof coatings perform well in areas with very high temperatures and areas that get a lot of UV exposure. Silicone creates a slick roof surface, and another layer can applied to recoat the roof. These coatings are not ideal in highly visible areas, as they tend to pick up a lot of dirt. Silicone roof coatings are not very resistant to trauma, so avoid using this coating in high traffic areas.

SEBS- SEBS rubber coatings were specifically designed for metal roofing systems, they can also be used on concrete, urethane foam, modified bitumen, and single ply membranes. It has superior adhesion and low permeability which helps protect against fungi and algae growth. SEBS coatings provide seamless coverage and superior resiliency.   

The color of the chosen coating can also play an important role in the decision making process, especially in warmer climates.  Pigmentation options are often limited which leave the most common colors of white, black and gray because of the superior UV resistance. White can typically reflect over 80% of the UV rays in keeping with the nation’s Energy Star program. Please keep in mind that over time roofs collect dirt, and a white, reflective roof will lose some solar reflectance over time. It’s important to have an annual maintenance program in place with a professional, certified roofer to clean and maintain your roof coating and identify any small issues before they become large and costly ones.

The color of the roof coating you choose does not only matter for the color scheme of the your building. White, black, and gray are common colors because of their UV resistance. White roof coatings usually reflect about 80% of UV rays. It is important to remember that roofs collect dirt and debris over time, so the roof will lose some of its reflective properties as it ages. It is important to make sure that you have a preventative maintenance plan in place to maintain your roof coating. If you are interested in a roof coating contact Peck Brothers today.
