Copper or stainless steel flashings are recommended if you live within a mile of the ocean. The salt air will corrode galvanized metal in as few as five years.

Roofs with rusted flashings will fail at the perimeter and at each roof penetration around pipes, vents, chimneys and skylights.

Although copper is around five times more expensive than standard galvanized flashing, it is a great value when compared to the cost of a complete roof replacement. Copper and stainless steel can last 50 or 60 years.

Over the years, I believe I have seen it all. A homeowner from Redondo Beach called in distress over a brand new roof that continually leaked despite a lack of rain.

The roofer who did the job refused to repair anything because he knew the roof was properly installed and not leaking. Regardless, the homeowner resorted to catching raindrops in pots.

To find the problem I removed the tiles and roofing material from the ridge above the leak. I found saturated plywood and rotting wood. The humid beach air, after rising up a high interior wall and being blocked by the waterproof roof, condensed and later dripped down.

To alleviate the problem, I replaced the wet wood and vented the roof ridge to allow the warm, moist beach air to escape freely.

Update: We ran into the same problem inland in Pasadena. A vaulted ceiling was stained at the peak of the ceiling revealing the same problem of improper ventilation.
