Rain is constant; leaks rarely are.
Seattle averages around 37 inches of rain spread across roughly 150 wet days a year. That long, gentle soak is harder on a roof than one big storm: water finds the slow failures first—lifted flashing at a chimney, a cracked pipe boot, a valley packed with fir needles. Most leaks we investigate are not a “bad roof,” they are one detail that gave up. A good inspection tells you which it is before anyone talks about replacement.
