Through the years we have been called to repair cracked and broken clay tiles that were properly installed but improperly walked upon by painters, termite companies and other workers.
A smart solution is to install the roof using foam instead of nails. The foam creates a cushion under the tiles allowing painters, workers to walk on the tiles as if it were a floor. This benefits painters painting the second story, fumigators dragging heavy tarps over the roof, satellite and solar panel installers and anyone who needs to access the roof.
Further, these tiles will not move or fly off in high winds.
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.
The most common issue that causes torch down roofs to fail is improper sealing around the edge metal flashing or pipe and vent flashings. Water often penetrates the roof due to a lack of adhesion of the torch down material to the edge metal. Water can leak through the ceiling and walls and migrate into the house.
If the roof is new, you can patch it without problem. If it is already 15 years old, the roof should be replaced.
Proper patches must be thoroughly cleaned and prepared. If improperly patched, a weak spot develops at the seam.
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.
