Metal roofs last a long time, but they rely on fasteners, seams and sealants that need attention. A metal roof inspection catches backed-out screws and failed sealant before they become leaks.
What we check
- Exposed fasteners and washers: loose, backed-out or missing
- Standing seams and panel laps
- Sealant at ridge caps, penetrations and trim
- Scratches, corrosion and finish wear
- Flashing at walls, curbs and skylights
- Gutters and edge trim
Problems we find most often
- Washers that have dried and cracked under exposed fasteners
- Sealant that has shrunk away from trim
- Corrosion where dissimilar metals touch
- Panels damaged by foot traffic
How long does it last?
Metal roofs typically last 40–70 years, though exposed-fastener systems usually need fastener and sealant maintenance along the way.
Signs it is time for an inspection
- Rust spots or streaks
- Leaks at screws after rain
- Loose trim rattling in wind
Questions
Do metal roofs need maintenance?
Less than most roofs, but exposed fasteners and sealants should be checked periodically, especially after strong winds.
