It’s a Question People Wonder About: Do Metal Roofs Leak?

Metal roofing has gained a reputation for durability and resistance to the elements. Homeowners generally hear that a properly installed metal roof should last 40–70 years. Even with that impressive tenure, doubt persists. Why do metal roofs leak? The do metal roofs leak issue comes from experience with older or improperly installed roofs.

The reality is that a properly installed metal roof is one of the tightest roofing systems to water penetration. But even the strongest roof is not completely immune. While an error in installation or a lack of maintenance can cause problems even for metal, it does not mean that a metal roof is impervious to issues.

The Real Answer: How Well It Works Varies by How Well It’s Installed and Maintained

Yes, I’ll cut straight to the chase: metal roofs do, in fact, leak. But the longer answer is more complicated. Roofers constructed metal roofing panels by panel and keep them in place with fasteners and protective sealants, which together protect a house from rain, snow, wind, and extreme temperatures.

The leaks are mostly due to the way the system was constructed, not the metal itself. This is one reason why it is important to hire an experienced roofing contractor. At NextDoor Exterior Solutions, we get the science of metal roofing and make your project look great and last long.

Top Reasons For Leaks on Metal Roofs

Improper Installation of Fasteners

Poorly driven fasteners are one of the leading causes of leaks. If the screws are under-tightened, the water may get under the washer. The washer could crack and cease to provide its protective seal if it’s over-tightened.

Panel Overlaps and Seams

Metal roofing sheets interlock, but seams are sensitive and must be aligned.

Damaged or Failing Sealants

Sealants are applied to penetrations (vents, skylights, chimneys). Those sealants can have a lifespan that, when coming to an end, is difficult and/or too expensive to repair, changing areas from strong to weak points throughout the roof.

Expansion and Contraction

Metal tends to thermally grow and thermally shrink. And if the roof was not installed with such considerations, the movement can even pull fasteners and leave gaps.

Flashing Errors

Flashing is also necessary at the roof edge, valleys, and penetrations. Leaks are often due to the flashing that is installed wrong or not at all.

How You Can Tell If Water Is Leaking Through Your Metal Roof

It’s not always easy to know whether a metal roof is leaking. Homeowners should be on the lookout for:

  • Watermarks on ceilings or walls
  • Damp insulation in the attic
  • Downstream Hazard: Dripping Run-Off Puddling from heavy rains
  • Streaks of rust next to seams or screws
  • Mold or mildew growth indoors

Catching those early will prevent costly damage to the substructure below.
