Roof leaks are the biggest problem of architects and building owners. Extreme roof temperature changes require durable and flexible flashings. The National Roofing Contractors Association states: "Pitch pockets or pans by their design, are not intended to be continuously watertight. Their use should not be encouraged since better methods are available to accomplish the same end. Pitch pans or pockets require frequent inspection and maintenance, and usually a great deal of damage can occur before the leak around a pitch pan or pocket is evident."
