Finding the actual source of a leak
Water rarely enters a roof where it shows up on your ceiling. It travels along decking, rafters and insulation before it finds a place to drip, so chasing the stain almost never solves the problem. We trace leaks back to the real entry point, which is usually failed flashing at a chimney, wall or skylight, a nail pop, a cracked boot around a vent pipe, a valley that has worn through, or ice-dam damage from a previous winter. Diagnosing it correctly the first time is the difference between a repair that lasts and one that reappears with the next storm.
