Our house is pretty old, built in the late 1800's. Over time, the back
of the house (as well as our neighbors') has subsided a bit. Hasn't
caused any foundation problems, but it does mean that in places water
doesn't flow off the roof quite like it's supposed to anymore.

One problem is as shown in the photos linked to above. The built-in
gutter doesn't work anymore, and the water pools in a corner of the
roof (above the porch), flows over the side onto our deck, causing a
bit of damage including allowing mold and moss to grow where it
shouldn't.

How would you fix this?

I can see at least two ways:

1. Build a kind of dam using a plank of pressure-treated wood along
the side of the roof, so that water is forced to once again run down
the original gutter spout. I'd install the wood, cover it with tar
paper and roofing compound, and we'd be good to go. Maybe instead of
wood I'd use some sort of large vinyl drip edge or whatever, if I
could find it. I'd try to install the wood in a way as to not pierce
the roofing material already there, so leaks can't develop.

2. Install a new gutter alongside the edge of the porch overhang. I'd
have to connect it to the main downspout (shown in the pics) or else
install a new downspout somewhere close.

Advice and opinions? Much appreciated! Thank you!


Really hard to tell but it looks to me like some demolition and rebuilding
is in order. If it's as old as you say you probably have a log of rot damage
that needs to be removed. From what I can see I'd start over completely.

If you're trying to just get by until you can afford to do the job right
maybe add some drain spouts.

I've got gutter problems too. We have very large live oaks that drop crap
almost year round and I don't have any guards. I was thinking of using this
but it's kind of expensive and I'm not sure if it's the answer.
