Roof coatings are a cost-effective way to improve an existing roof’s service life. In order to benefit from its features, it has to be installed properly. In today’s post, local roofing company WaynCo Roofing, LLC discusses the critical errors an installer must avoid when applying roof coatings.
How Do Roof Coatings Work?
Roof coatings are applied as a viscous fluid that creates a durable barrier on the roofing surface after curing. It can be applied to virtually any roofing surface, but works best on nonporous surfaces like metal and single-ply membrane. Properly-applied roof coatings provide three key benefits:
It helps extend the life of an existing roof — Roof coatings help protect the roof from exposure to rainwater and improves its resilience against impact, punctures and foot traffic.
It helps protect the roof against ponding water — Ponding water is one of the most common problems inherent to low-slope roofing. Roof coatings create a secondary barrier that protects seams and joints. It also helps slow down the effects of ponding water, allowing ample time for your roofer to address underlying issues that lead to ponding water.
It helps improve the roof’s energy efficiency — Roof coatings come in white or light colors that make the roof more reflective. This helps the heat absorbed through the roof, which would otherwise raise indoor cooling requirements and result in higher utility bills.
Critical Installation Errors
A roofer who applies roof coatings has to have the training to make sure the following critical installation errors are avoided:
Coating too thinly or too thickly — A roof coating needs to be at a certain thickness to achieve full efficacy. Evaporation must be taken into account, as the resulting roof coating is thinner when dry than it is when wet. There is also the other extreme, where roof coating is applied too thick, which can result in blisters, bubbles and wrinkles.
Improper mixing — Roof coating needs to be mixed thoroughly to prevent heavier ingredients from settling at the bottom of the container, which could result in uneven areas after application.
Applying before rain storms or during cold weather — Roof coatings need to cure in certain conditions such as temperature and humidity levels. Not meeting these conditions can result in less-than-optimal performance.
