Roof Problems · For owners & managers
Rust and Backed-Out Fasteners on Metal Roofs
Metal roofs move with heat every day. Over time screws loosen and rust spreads at laps.
Signs
Drips along panel lines, rust streaks, and screws that turn freely.
Repairs
Oversized fastener replacement, lap sealing, and rust treatment.
Long-term
Coatings or a retrofit roof when panels are widely rusted.
Common questions
- Is rust a structural problem?
- Rust-through panels need attention. Surface rust can be treated.
- Can I paint it?
- Use a roofing coating system, not house paint.
