I have plastic panels on a roof over a large deck, and the roof
leaks where it is in contact with the top of the wall of my house. (The
gutters were torn out where the roof was attached to the house.) In
particular there are leaks where the wooden beams that supported the
corrugated materials are attached to the house. (which has traditonal
shingle type roofing) A handyman plastered the leaks with silicone and
that didn't solve the problem. Then he put flashing on the shingles,
and it still leaked in the same places. Following that I visited the
home of a friend who had a similar corrugated roof, and his roof had
flashing (and not much silicone), and it didn't leak. Does anyone have
any ideas as to how I can stop the leaks. Any help would be
appreciated because there is a nice deck under the roof.

Thanks,

Take it apart, and put it back together correctly, with a continuous
flashing going from fully under a shingle layer, to well out over the
corrugated. Water should have no where to go, but downhill where you want
it. Use gasketed nails and/or a daub of sealant wherever you penetrate the
flashing. If corrugated roof isn't well sloped, some of the purpose-built
corrugated gasket stuff may be called for, to avoid a backwards water path
under the flashing. From your description, I suspect the ledger board for
the deck roof, and probably the old gutter board, are probably rotted by now
and need replacing. There are supposed to be standoffs between ledger board
and house, so water doesn't get trapped, and air can dry it out. One of the
DIY books about roofing/decks/sheds etc, probably has pictures that explain
it better than I can.

Flashing should go under the shingles.
