Roof-on-roof methods of leak remediation leave in place existing roof membrane material and saturated material (e.g., insulation). An example leak-remediated roof includes a layer of saturated insulation over a roof deck. A membrane over the insulation has one or more failures that have permitted the insulation to become saturated. A grid of cuts is made through the membrane and the insulation down to the roof deck. A mechanical vent is placed over a cut of the grid A strip of mesh vent is installed over a cut of the grid.
