Roofing systems are designed so the water flows downward from high point to high point until it runs into a gutter or off an edge. Most roof leaks are caused by a flaw in this progression—water pools up in one spot and begins to damage the material beneath. The resulting moisture penetration can gradually impact the integrity of your house, including your electrical wiring, insulation, drywall, and wooden supports. The key to a complete repair is properly identifying where the leak is occurring and making sure the patch is comprehensive.
