Revealing the Less-than-lustrous Side of Metal
Satisfaction with a metal roof can be short lived. The once-alluring benefits of low installation cost and fire resistance can dull in comparison to the necessary upkeep. In just a few years, fastener back-out and rust can lead to leaks that require costly maintenance.
Coatings and spray-on foams are one possible solution; however, coatings will need to be reapplied every three to five years while poorly applied spray-on foams can result in unnecessary and excessive pounding water.
Starting over may seem like the surest means to restore water tightness, but beware, as replacing the metal roof comes with added risks. Installation of a new metal roof can disrupt operations and expose the interior of the building to the possibility of roof leaks.
