Emergency tarping in Janesville

Tarping is what happens when a roof cannot be made permanently watertight the same day — wrong weather, materials that need temperature to bond, or damage too extensive to repair before the next rain. A properly anchored tarp buys weeks. A weighted one blows off in the next storm and takes shingles with it. The difference is whether it is fastened into sound structure above the damage and run far enough up the slope that water cannot get behind it.

What the job involves

  • Tarp sized and positioned to run above the damage to the ridge
  • Mechanical anchoring into sound structure, not weights
  • Assessment of how long the temporary cover will hold
  • Scheduled return for the permanent repair

Signs you need it

  • Missing shingles over an area too large to patch immediately
  • Storm damage with more rain forecast
  • Structural damage that needs assessment before permanent repair

Why roofs fail in Janesville and Rock County

Janesville 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 Rock 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.

Janesville has a population of about 63,575, and the housing stock here sets the pattern for what fails first on a roof.

Questions about emergency tarping in Janesville

How long does a tarp last?

A properly anchored one holds for weeks to a few months depending on exposure and UV. It is a bridge to the repair, not a solution — the material degrades and the fixings work loose.

Will a tarp damage my roof?

Correctly installed, no. Badly installed, yes — weighted tarps shift and abrade shingles, and fixings driven into the field of the roof create the exact holes you are trying to cover. Anchoring goes into sound structure above the damaged area.
