When properly installed and maintained, a metal roof can last 50 to 80 years. However, the fasteners used to attach the roof may have a shorter lifespan than the roof panels, so it’s a good idea to inspect your roof every few years to check for wear and replace any damaged components. Metal roofs installed over shingles don’t last as long as tear-offs since the underlying roofing components can deteriorate over time, and the added weight can stress roof supports.

Metal roofs don’t inherently leak more than shingles, and when properly installed, they can actually offer greater protection against leaks. However, poor installation, improperly sealed fasteners, or thermal expansion issues can lead to leaks over time, so professional installation and regular maintenance are crucial.

In many areas, chimney repair companies need to be licensed, but it depends on your state and local municipality. You can check with your local building department to see if companies need licenses, and then you can use Angi’s license lookup tool to confirm that the company you’re considering holds the proper license. It’s a good idea to confirm that the professional is fully insured, and you can ask about certification from organizations like the Chimney Safety Institute of America (CSIA). These certifications aren’t mandatory, but they help ensure a professional repair.

The lifespan of a roof patch depends on which materials you use and the severity of the damage. Temporary solutions like tarps or plastic sheets last a few weeks to a few months, while roofing tape or caulk may hold up for a year or two. Permanent patches using roofing cement, flashing, or replacement shingles can last several years as long as they're properly maintained. Regular inspections and touch-ups can extend the patch’s lifespan, but eventually, a full repair or replacement would be needed.
