Metal roofs experience thermal expansion and contraction alongside other factors that create susceptibility to seam and fastener problems, cracks and leaks around penetrations, and rust and corrosion. If your facility has a metal roof, your building's watertight integrity faces compromise.
Several solutions exist. Sealing and coating represents an inexpensive option that re-seals exposed seams and applies waterproof coating. However, this method only protects against rain temporarily, since the roof continues expanding and contracting, eventually rupturing new seals and coating.
Spray-on foam and sealant covers the metal roof with urethane foam, then seals it. While this protects against rain and interior drips, irregular foam surfaces typically collect water, and most spray-on foam warranties exclude damages from ponding water.
Complete roof replacement with new insulation and steel addresses all problems temporarily—until vulnerabilities resurface because new metal roofs share the same weaknesses. This approach proves costly, requires heavy equipment, and disrupts normal operations while potentially exposing building contents to elements.
Single-ply membrane retrofit solutions offer a superior alternative. These cost-effective solutions typically install directly over existing metal roofs.
