A metal roof is about as low-maintenance as roofing gets. There’s no annual scrubbing and no big to-do list. Still, a quick check once or twice a year helps it hit its full 40 to 70 year lifespan. Here’s the short version.

Your yearly metal roof checklist

• Rinse off leaves, needles, and dirt so debris doesn’t trap moisture.
• Clear the gutters and valleys so water drains freely.
• Look over the trim, ridge, and flashing for anything loose.
• On exposed fastener roofs, scan for screws that have backed out and re-seat them.
• Check for scratches in the paint and touch them up if needed.
• Trim back branches that rub or drop debris on the roof.

Exposed fastener vs standing seam upkeep

Exposed fastener panels use screws with gaskets that can wear over many years, so they get a quick fastener check. Standing seam hides its fasteners and needs even less attention. The difference is covered in standing seam vs exposed fastener.

What to avoid

Don’t use harsh abrasives or a pressure washer on full blast, since that can dull the finish. Mild soap and water handle almost everything. Avoid walking on panels more than you need to, and step on the flat, supported areas.

When to call a pro

If you spot a leak, damaged panel, or lifted seam, get it looked at. Small fixes are cheap. Our panels carry a Sherwin-Williams WeatherXL SMP finish with a 40-year paint warranty, so fading is rarely the issue.

FAQ

How often should I clean a metal roof?

Once or twice a year is plenty for most homes. Do it more often if you’re under heavy tree cover.

Do metal roofs rust?

Modern coated steel resists rust for decades. Cor-Ten is the one exception, and its patina is on purpose. See Cor-Ten weathering steel.

Bottom line: rinse it, clear the gutters, and glance at the fasteners once a year. That’s most of it. Questions about your panels? Give us a call.
