We have an issue with a moat forming around this garage. It does have a french drain all around it but the rain here is overwhelming most of the time. I know the lack of gutters is the reason and I plan to fix that. I was wondering if I can just toss some gutters on this or is there something I should do with the facia board to improve it beforehand? It seems like it is 3/4 x 4" which doesn't seem like much but it's a small garage so I wasn't sure.
