Wm, Client with ancient barrel tile wanted to keep the precious and didn't want us breaking a single one (we cracked three or four just investigating with a 195lb person up there (me). Roofer was called in. Tile was removed under the array all the way to eave. Comp shingle was laid under top row of tile and all the way to eave. PV array was installed and framed (centered) nicely. Two rows of barrel tile were replaced below bottom edge of array to eave. One could not see posts or flashings under the array, and gave the array a floating look over the regular tile roof common to the rest of the rooftop. Water drained into rain gutter at edge of eave underneath array. Water drained over AND under last two rows of barrel tile into gutter solving aesthetic issue. Cooling air flow was still sufficient under array.

There was no good way to divert water from under the lower tiles. The roofer first tried using some roll roof that cracked and then used lead flashing. There was still a mosquito pond where the water pooled. Also, the "built in" look creates cooling flow restrictions. We eventually gave up on the built in look.
