I've got a small patio with a chimney wall at its back and a sloped roof on either side. I need to install a gutter system and I'd prefer to not have the water flowing across the patio. Should I attenpt to bring the water down the slopped roofs? I know my question is a little vague, so I'm including a couple of photos to add a visual. Any assistance you can offer is greatly appreciated.

Hi Cnsdirect. I should start by saying I don't see a cricket extending past the chimney walls which is a best practice at this problem location. Next time you do roof work you might want to consider adding this detail.

Are you sure need gutters there? Half the sloped roof area is protected by the overhang so you would be going through a lot of trouble for not much runoff. I think gutters would look pretty awkward there as well. I can't think of any good solution other than cutting through your concrete patio (assuming) to put in a drain for the downspout in the corner.

Often seen on homes without gutters is a device to divert rain water off the roof away from doors. Don't know what it is called but it amounts to a piece of angle aluminum at an angle on the roof to divert water away from the door. Seen here in red it would divert water from that part of the roof to the roof over the extended area to the left.

I like the idea of the flashing along the roof to divert the water on the left side of the chimney to the longer slope where you would have eaves. Definitely no small pieces of trough on the little sloped roofs of the chimney if that is what you were thinking. Also If you run your trough from the left side of the chimney towards the little gable end that protrudes down further you can put a mitre there and run trough down that slope to another mitre at the bottom and along the lower side like you would have any ways.

If I understand the layout correctly, another idea is to put your eavestrough on the roof between the chimney and brick wall where you want it... and then bring the downspout from the left corner down about a foot and then mount it on the brick wall under the soffit. i.e. the downspout runs parallel to the soffit near the top of the brick wall, and then turns vertical once you reach the end of the brick wall on the left.
