Metal Retrofit Systems
The most effective way to roof a pre-engineered steel building with standing seam or corrugated panel roofing is through the installation of a metal retrofit membrane system. Typically, within 20 to 30 years of construction, roofing details relying on sealants and screws on corrugated buildings tend to deteriorate, leading to leaks. While many companies attempt to address this issue with coating systems (essentially white paint), no product can form a lasting bond with weathered metal, often lasting no more than 5 to 10 years.
For a comparable price per square foot to a high-end coating, HKS offers the installation of a metal retrofit membrane system, providing a No-Dollar-Limit membrane warranty, increased R-value, and enhanced aesthetics with new metal edge trim and gutters. Essentially, the existing metal roof is transformed into a new steel roof deck. The process involves fitting a base layer of insulation to match the existing metal roof's profile and enhancing edges with wood blocking. A top layer of insulation or recovery board is then installed with a membrane system, similar to other layover systems. Unlike coatings, metal retrofits can be installed year-round, regardless of temperature.
