While metal roofs require significantly less maintenance than other roofing types, they still benefit from regular attention to ensure their 40+ year potential lifespan. Annual inspections should check for loose fasteners that may develop from thermal expansion and contraction, particularly around flashings and trim pieces. Clear away debris accumulation in valleys and behind chimneys where moisture retention can potentially cause problems. Examine sealants around penetrations and replace as needed—typically every 10-15 years depending on exposure conditions. Watch for any surface scratches that might need touch-up paint to prevent potential corrosion. Clean periodically to remove airborne contaminants and biological growth, particularly in shaded areas. This minimal maintenance regimen protects your investment while maintaining your metal roof’s performance and appearance.
