In a cold climate, your quote should explicitly include ice and water shield at all eaves and valleys, a balanced ridge-and-soffit ventilation plan, and decking inspection — ice-dam damage is hidden until the next thaw. Push back if a Janesville contractor's quote skips any of these — missing line items in the bid usually surface as change orders during the job.
