Standing Seam Copper – Intersecting Valleys
Looking for opinions on this roofing situation.
Existing open porch with 1:3 slope roof. Has been under “temporary” cover for 5 years and now permanant roof with inlaid gutters is going on.
Valleys are in green. Slopes of adjacent surfaces in red.
This corner has demonstrated a desire to accumulate large amounts of snow and twice has generated a huge wedge of falling ice created by the melting snow pack. Huge defined as a triangle 7 feet on a side.
So – before I get the solder out and go to town I’m scratching my head to see if a different or better solution comes to mind. Snow guards?
At the top of the image from left to right is a “hip” at the end of the shed portion of the roof. At the bottom of the image is the intersecting turret roof with tapered roof panels.
Suggestions appreciated.
Thanks.

You need to get the attention of SeeYou.
Ithink I'd need a photo to make heads or tails out of this
or an elevation or three

You were able to post a sketch, take a picture or two and post that-it'd be much easier to explain once the thing has been seen.
thanks.
nice

Safety in numbers.
Confusing?
Come on guys - it seems pretty clear to me! :)
Epic thunderstorms today so pics won't be available until sunny Sunday.
Thanks for looking and the replies and I'll get more info posted ASAP.
In addition to the sliding ice concern I'm worried about keeping the water going the right direction with all the intersecting planes.This is (as my local coppersmith called it) a "cheaters" standing seam roof. Gutters and valleys etc are all soldered but the standing seams are simply a single fold, crimped and dimpled - not double lock.

epic?
Where the heck do you live that it rains all day...................epic-lee
And what better way to show the fall of those converging roof planes?
Get under some overhang, use an umbrella............whatever-post the pics.
thanks.
I printed your diagram, cut it out, and attempted to fold it as best I could to match the slope lines. Based on that, and without knowing what's "uphill" from this roof, I'd say that the upper right roof segment should be extended down and to the left to "subsume" the triangular section, leaving you with only one valley, roughly where the bottom valley is now.
What you've got is what you've got. I don't see any way to change anything that will reduce the output from the roof. Snow guards will help hold the snow on the roof if that's your only objective. With all the hips and valleys, snow guards are going to be tough to place for maximum effectiveness.

Still raining here in WI (no longer epicly) but I remembered I had some older pics that would work.
Thanks for the thoughts folks. Here are some pictures that might help. The aerial may be the easiest to look at. The area in question is the inside corner above the front door.
The install shot is from the back porch a couple of years ago but rest is similar.
As you say seeyou I'm probably stuck with what I have but before I put the pedal to the metal so to speak wanted to give it one last shot. I have the gutters just about in and am about to start on the valleys this weekend.
My other valleys are W style with overlays along the sides to catch the roof panels. I'm thinking for here I'll bend up V valleys and make the one out of a full sheet so it wraps up on that narrow odd shaped slope and eliminate some of those tiny roof panels entirely. I also think two intersecting W valleys is asking for trouble at that bottom point - a 1 inch high trap for water. Also thinking I should bend in an integral flange on these instead of the overlay piece to minimize opportunities for water to back up under the metal when all that snow is sitting there melting.
Hoping a few snowguards will be enough given the low slope.
Thought about extending that shed roof line over as was suggested and creating some sort of pediment above the door but haven't given that much thought to be honest.
Any other thoughts appreciated.

Thanks!
I for one would have never gotten that porch from the original drawing.
Now I'll defer to someone who knows copper and roofing.
See you,
later.
But, if you want to show some of the woodworking, I'll be the first to sit down and have a look.
thanks, and best of luck.
As is too often the case, the structure has been designed without regard to how the roof would work out. It's an attractive design, just seriously impractical.
My "last gasp" solution would be a flat (I don't mean level) section in the trapezoid between the stair opening header and the house, bounded by the left valley and the right ridge, letting the top end go "wild".
Looks like this is too far along to make it right. The stairs are in the worst place they could be and the one far-back triangled section could have had a bit less pitch to change the way this all iontersects, but with what you have, maKing that smallest triangle and the valley it drains to all of one piece is the best idea I can see

As Dan Houlihan would say...
Thanks for taking a look all - if the guy that designed this was available I'd bring him on to have a chat but he died in 1899 and probably wouldn't have been familiar with how to use the web anyway.
I am going to take a look today at changing that double sloping polygon into a pediment with a ridge and valley That may or may not help but might simplify my roofing and eliminate some flat seam soldering.
Enjoy the holiday weekend!
