Metal roof leaks in Lookout Mountain

Metal almost never fails in the middle of a panel. It fails at the fasteners, where thermal movement backs screws out and flattens the neoprene washers underneath, and at seams where sealant has gone brittle. A screw standing proud by a couple of millimetres is an open hole, and there may be hundreds of them on a roof. Both failure modes are invisible from the ground and both are straightforward to fix — which is why a leaking metal roof rarely needs replacing.

What the job involves

  • Survey of every fastener for backout and washer condition
  • Replacement of failed fasteners with oversized screws where needed
  • Seam and ridge inspection with resealing where sealant has failed
  • Check of penetrations, curbs and any transition to another material

Signs you need it

  • Screws standing proud of the panel surface
  • Rust streaks running down from fastener heads
  • A leak that worsens on hot days as panels expand

Why roofs fail in Lookout Mountain and Walker County

Lookout Mountain sits in the Blue Ridge foothills, which puts it in a different roofing climate from most of Georgia. The mountains get real freeze-thaw cycling: water works into a hairline gap in flashing during the day, freezes overnight, expands, and opens the gap a little wider. Repeat that through a Walker County winter and a joint that was watertight in October is leaking by March. Ice at the eaves is the other one — meltwater running down a warm roof refreezes over the cold overhang and backs up under the shingle course, which is how water ends up inside a roof with no visible damage at all. Steep pitches shed snow well but make access harder, and older stock here runs to standing-seam and pressed metal, which fails at the fastener rather than the panel.

Lookout Mountain has a population of about 1,641, and the housing stock here sets the pattern for what fails first on a roof.

Questions about metal roof leaks in Lookout Mountain

Do all the fasteners need replacing?

Not always, but they went in on the same day and have had identical weather, so if a number have backed out the rest are on the same trajectory. Doing the whole roof at once usually costs less than returning twice.

My metal roof leaks but there is no visible damage. Why?

That is the normal presentation. Fastener and seam failures are not visible from the ground and often not obvious from the roof either without checking each one. The panel itself is almost never the problem.
