Flashing replacement in Iowa County

Flashing is what seals every junction on a roof — walls, chimneys, valleys, penetrations — and it is where most leaks begin. It fails through corrosion, through movement opening the joint it was set into, and through having been installed as a surface detail rather than stepped properly into the courses. Replacing it means working into the surrounding material rather than sealing over the top, which is why it costs more than a patch and why it lasts.

What the job involves

  • Survey of all flashing runs — wall, chimney, valley, penetrations
  • Removal of failed flashing rather than overlaying it
  • Correct stepping into shingle courses and masonry joints
  • Replacement of corroded fixings and sealant at terminations

Signs you need it

  • Rust streaks or visible corrosion on flashing metal
  • Leaks confined to one junction rather than the open roof
  • Sealant visibly applied over flashing by a previous repair

Why roofs fail in Iowa County

Iowa County has a winter long enough and cold enough that ice damming, not storm damage, is the dominant cause of roof leaks. The mechanism is heat loss rather than weather: warm air escaping into the attic melts snow on the upper roof, the meltwater runs down and refreezes over the cold overhang, and the resulting ridge of ice backs water up beneath the shingle courses until it finds a way in. The roof itself is usually in perfect condition. Repeated through a Iowa County winter, freeze-thaw also works every flashing joint progressively looser, and spring brings hail and straight-line wind on top. The reason this matters is that fixing an ice dam leak by working on the shingles does not work — the problem is insulation and ventilation, and that is a different job.

Questions about flashing replacement in Iowa County

Why does flashing fail before the roof does?

It is thinner material in the most exposed position, and it sits across a joint between two things that move at different rates. On most roofs the flashing is the first component to need attention, often by a decade.

Can flashing be replaced without redoing the roof?

Yes. It means lifting and reinstating the surrounding courses, but it is a localised job on an otherwise sound roof and far cheaper than replacement.
