Valleys are not supposed to be level?

[RickSab]

Here's another I could use your opinions on. This house has two interesting valleys. One on the front, and another in the middle. The middle one has several squares of roof dumping in it. Oh, the gutters on the dormer are open at the back at the bottom of that valley. I included a long shot of the house from the rear to give you an idea how much roof there is.

Thanks for your ideas on this one.

The gutters shedding water onto the main roof plane is a common practice around here. The gutter should have a half moon cut in it so debris can not plug up the drainage point of the gutter.

The valleys should not be completely flat and should be detailed as a flat roof system...... at least around my area.

Just an opinion-- that is a crappy roof design.

The pictures you posted don't show it for sure but it looks like you may have what is called "dead" valleys. Look at the third picture down in the link below. It shows a way of dealing with dead valleys.

Definitely a really crappy roof plan.

Putting a saddle in the middle of the mess might help, but it's hard to tell without seeing it up close and personal.

At this point, about all anyone could do to "improve" the situation would be to install WR Grace everywhere in and around the "valley". Personally, I call them pans, as in, a place that collects stuff.

My dang computer won't open any of the link's in this site for some reason. I have never had this problem before and have not changed any settings, etc. Any ideas? I click on the link, and the screen starts to open, but never does open completely.

Did you try clearing cookies and rebooting?

Hard to tell much from those pics.

Those valleys might have plenty of pitch to them and be roofed with a modified bitumin/flat roof material.

I don't see a problem.

I think if you caulk up the valley it'll be ok.

Deadend gutters - bad news.
