Metal roofing takes center stage in this episode as we examine both metal shingles and metal panels. Learn the key distinction between metal shingles (less than 3 square feet) and metal panels (3 square feet or more). We explore naturally weathering metals like aluminum, copper, and stainless steel, as well as metals requiring protective coatings such as galvanized steel and painted finishes. Discover the impressive service life of metal roofing (50+ years) and understand the three main installation methods for metal panels: standing seam, sealed seam, and non-sealed lapped seam roofs. We'll cover proper installation techniques, fastener compatibility issues, valley flashing requirements, and the pros and cons of installing metal roofing over existing roof coverings. This episode also addresses typical repairs, common defects, and important safety considerations when working with metal roofing systems. Essential listening for anyone involved in metal roof installation or inspection.
