Wind-driven rain is penetrating through the sill during construction
Our windows have been installed with sills wrapped in tar paper and peel and stick, flange caulked and corners sealed and entire flange tuck taped. Exterior building wrap not yet installed as our sheathing inspection has been delayed. Over the past couple of days of strong wind/rain storms, water is penetrating through to the interior sills. Before we go any further, is this likely an issue with how the windows have been installed or will proper exterior rain screen solve this issue???
