reducing shingle exposure

"Maybey i can just put a 1inch slot in the vertical leg of the 1 pc head flashing inbetween the units to let it drain without having to wrap it around the heads?"
You could, BUT, you will be creating a 'potential' weak link in the system.

My technique? I take 1-3 pieces of 12" metal and mock up 1-10 senarios before making a final decision. And a 6' piece never quite fits like that 12" mock-up!
I can't go back from this answer box, but I think thye were 2' skylights. That's only about 60" of back pan, with less than 4' of roof above it. Shouldn't be a problem.

After going back, I'm more confused. Are they 4' across? One view looks like 2'ers. other looks like 3-4'ers???
Only 38" to the wall. I'd still go full lenght.
Reason? They're not like a chimney between them where water can run around a back-pan. You join 2 pans there, no caulk in the world will work long-term, even with hemmed ends.
This is one of the very few that I might end consider a 1"-1-1/2" tall water diverter above the pan, about 6" longer on each end, come to think of it. You would sleep at night knowing that no amount of rain would ever back up enough to 'over-run' the top of the back-pan, which looks like it could be 4" tall for 6-8'.

Overkill, but bullet-proof.

they are 42'' wide and i see what your saying ,do you think i should make the diverter 2 pc pulling it up in the center to get some pitch to the outside of the skylites?

tomstruble

because of the roof pitch velux wants a raised curb

tinner666

I know they want a raised curb. I' haven't seen any problems with 3/12 roofs yet.

I would pitch a diverter about an 1" or 1-1/2" each way. It's only a 3' run, but that is a lot of snow above them. Put the diverter 8" to 1' higher and a monsoon won't casue it to leak.

u shingled that 2/12 section of roof??? are u crazy shingles are not made for that low of pitch. I would of used a peal and stick or single-ply system. Things that are made for low slope.

I was sure of that Ed. I was wondering if he had noticed any on the inside. I'm not much of a wordsmith, am I? Good thing I roof better than I talk or type, eh?
