We plan to replace the roof on our mid-century modern home in the SF
Bay Area (East Bay). We are considering the same type of roof (tar &
gravel), as well as modified bitumen and foam.

We need to also improve the roof drainage. There's currently no
gutters, downspouts, fascia board, etc., just flashing around the
edges. When it rains, water just spills over the edges in certain
places.

Any suggestions on what to do? Our preference would be to put up
fascia boards and coordinate some type of drainage solution with the
new roof. We're not sure how to go about this, or if we need a
carpenter or roofer for this. Also, any contractor recommendations in
our area are welcome.

Thanks for any help.
