Nevada's dramatic temperature swings and seasonal weather patterns can take a serious toll on commercial roof penetrations, especially around downspout systems that channel water away from large buildings. We responded to a Minden commercial property where leaking downspouts were allowing moisture infiltration through compromised roof penetrations. After checking things out, our team found corroded metal piping and deteriorating flashing where the downspouts passed through the roof deck, with water seeping into the warehouse space below and threatening the interior structure and stored inventory. Working from a scissor lift provided by the property manager, our licensed plumbers carefully looked over each penetration point, replaced the failing boot seals and flashing materials, and secured all connections to prevent future leaks. The vulnerable areas got reinforced against Nevada's freeze-thaw cycles that speed up metal corrosion and seal deterioration. The building's high-ceiling warehouse environment is now protected from water damage. The property owner has peace of mind knowing their downspout system can handle heavy Sierra runoff without compromising the building envelope.
