Metal roof leaks in Starr County

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
  • Check of penetrations, curbs and any transition to another material
  • Assessment of panel condition and any corrosion at cut edges

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 Starr County

Starr County is close enough to the Gulf to take the full force of tropical systems, and that is the storm profile that sets everything else. Hurricane wind is sustained for hours rather than gusting, which does something different to a roof — it works shingle tabs loose over an extended period and drives rain horizontally under courses that would shed any normal downpour. Then the heat and humidity do the slow damage. Roofs across Starr County run hot for most of the year, which ages the shingle and hardens every rubber and sealant component on it, and the humidity means that anything which gets wet inside the roof structure stays wet. A small leak here does considerably more damage over the same period than the same leak would further north, and mould becomes a problem much sooner.

Questions about metal roof leaks in Starr County

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.
