Many maintenance and engineering managers might only have to make a roof replacement-or-restoration decision once during their careers, and it can be the most complex project they will take on.The cost of tearing off and replacing a roof system can be staggering. Even restoring a roof at one-half the cost of a replacement can be more than enough to give managers major headaches.For managers not interested in absorbing that kind of financial commitment, roof coatings are a viable option to extend the roof’s life and also save money in the process.The Roof Coatings Manufacturers Association highlights seven myths about coatings that managers must consider to better understand important issues related to coating specification, installation and maintenance. For an expanded version of this article, click here. Myth 1: Coatings don’t work — When installed properly, some fluid-applied systems are as good or even better than the original roof.Myth 2: No maintenance required — Managers need to send someone onto the roof every year and possibly every six months, whether it occurs before the rainy season or in fall when leaves are blowing around to prevent them from clogging the drains.Myth 3: A new roof is disruptive — Fluid-applied roof systems typically are not disruptive at all, compared to a tear-off and replacement.Myth 4: Warranties do not matter — Read the fine print, and ask questions. The investment has to last as long as possible, so managers have to understand the process.Myth 5: Coatings hate ponding water — Some coatings actually perform well in ponding water, but still it is best practice to eliminate ponding water for many reasons.Myth 6: I can’t get an FM coating — Factory Mutual (FM) approvals for coatings are for complete systems, which include everything from the roof deck to the top of the coating system. Myth 7: Anyone can install a coating — Most manufacturers require that their contractors be approved to install their coating systems.
