The Basics of Roof Coating

What is Roof Coating?

Roof coating is a monolithic, fully adhered, fluid-applied roofing membrane that is applied on top of the existing roof surface. Unlike traditional roofing materials such as shingles or tiles, roof coatings are designed to be flexible and elastic, allowing them to expand and contract with the roof as it experiences temperature changes. This flexibility prevents cracks and leaks, providing a seamless and watertight barrier.

Types of Roof Coatings

There are several types of roof coatings available on the market, each with its own unique properties and benefits. The most common types include:

  • Acrylic Coatings: Acrylic coatings are known for their excellent UV resistance and ability to reduce surface temperature. They are economical and easy to work with, making them a popular choice for residential and commercial roofs.
  • Silicone Coatings: Silicone coatings offer superior water resistance and UV protection. They are highly elastic and can withstand extreme weather conditions, making them suitable for roofs that are frequently exposed to moisture or ponding water.
  • Polyurethane Coatings: Polyurethane coatings are known for their impact resistance and durability. They provide a tough, wear-resistant surface that can withstand foot traffic and hail damage. They are often used on roofs with high traffic areas or in regions prone to severe weather.
  • Asphalt-Based Coatings: Asphalt-based coatings, also known as asphalt emulsion coatings, provide excellent waterproofing properties. They are commonly used on built-up roofs and can extend the lifespan of the roof by sealing cracks and preventing water infiltration.

Each type of coating has its own advantages and considerations, which we will explore in more detail later in this guide.
