Although roofing technology has advanced in the past years to make roofing systems more durable, easier to install, and sustain lesser risk of damages, facility managers and industrial coating contractors agree that roof coatings play a very important role in the overall performance of any roofing system.
The essential function of roof coatings is nowhere more evident than during roof maintenance and repair projects. In cases of roof problems, the cost of replacing the roof is far too expensive when compared to the option of applying the correct roof coatings such as Elastomeric or Polyurea roof coatings. An elastomeric roof coating, in particular, enhances the roof by keeping it watertight for longer periods of time. Polyurea roof coatings, on the other hand, are rapid-setting and highly-reflective coatings that are useful as fire retardants.
Types of Roof Coatings
Many considerations like roof slope and surface affect the type of roof coatings that can be applied to roofing systems. Coating contractors commonly use Elastomeric or Polyurea roof coatings for many roof projects because of their unique ability to repair and protect the roof from damages.
The most commonly used roof coating is acrylic elastomeric coatings, which not only extends the lifespan of the roofing system, it is also an environment-friendly coating formulation.
Unlike acrylic elastomeric coatings that are appropriate for sloped roofs, butyl elastomeric coatings are more suitable for flat roofs and water ponding. Other elastomeric coating formulations are polyurethane coatings that are very effective in coating rubber and single-ply roofing systems, and silicone coatings which are useful in silicone-coated roofs.
Polyurea roof coatings, on the other hand, provide a strong and seamless coating layer for metal and concrete.
