>First:

still in

antenna.
>Will this cause me problems?


Only if one of the trees falls on a guy wire in a storm.


>Second question:
>My house has a metal roof; about 29 squares of it.  This will be
about 65 ft
>below the antenna.
>Any thoughts on how much this will impact the pattern?

It will not. I highly recommend ON4UN's new book, "Low Band DX'ing."
It tells how all this good stuff works. In a nut-shell, the RF from
Yagi at
85 feet will hit the ground a long way from your metal roof.

GL!
