Metal roofs have been used in construction for a long time. Typically the roof will be a standing seam or through-fastened system. Metal roofs are often bare (galvanized) or have a factory-applied paint system. Although they have expected service lives of 30 - 75 years, these systems can be affected by several issues: subject to seams popping open as well as backing out fasteners; factory paint systems can fade greatly over time depending on the color and resin type; and bare (galvanized finish) roofs can actually start to rust over time and corrosion can be a major issue due to roof AC condensates that contain copper (dissimilar metal). These issues can greatly reduce the expected service life by as much as 50%.
Thermo Manufacturing can provide long-term, sustainable solutions for difficult roofing conditions. The links below cover our standard recommended systems for bare (galvanized) metal roof types.
If actual project conditions are such as to be outside the scope of the normal waterproofing practices that are referenced in the documents below, steps should be taken to ensure the restoration remains in compliance with nationally recognized waterproofing practices such as those found in the National Roofing Contractors Association Manual. If the system is applied according to our published specification and guideline, and after successfully passing a final inspection, and then accepted by Thermo Manufacturing Systems, LLC, the system would qualify for the specified warranty.
