Thanks, guys. I am curious what Kurt sees specifically to tell him this is a stinker in wind driven rain situations. For 10 years on original shingle install (old work not new) it did great, then after re-shingle if started this leaking business in big wind storms and as near as I can tell in only one spot, high left side. Now that is leak entry point not necessarily start location of course. But the fact is there is a whopping 20 lineal feet of curb to roof contact here (curb is about 4 x 6') and only one little trouble spot, so is the install really so junky???

Tried to get some photos this am, but it was 27 and the roof was a frosted skating rink. Will try again tomorrow after Thanksgiving. So much appreciate all of your input and wish you all a good Thanksgiving holiday.

I will try to get some photos done today or tomorrow and post. The original Velux flashing kits were used for the curb and the skylight itself. That was step flashing on the then shingle roof and the flashing clad kit on the skylight and curb. For 10 years perfect, then at re-roofing to shingle the wind driven issue started and now with the metal re-roof same deal. I will be quizzing the roofer as to exactly what he did. Of course it could be an issue in the skylight itself, something he did not touch in his work. Yes, the skylight crosses several metal sections. I see the point made by Marc, assume he means flashing in each standing seam section, not something over the seams...Roofing Mfg is Englert by the way, which I understand is reputable.

Thanks for your post. Please see first line of original post. This is a curb mounted Velux up on a velox curb that increases the skylight pitch, i.e. the curb looks like a cheese wedge. It never leaked for a decade....

Makes sense....Based on what you said before, I should probably ask the guy what he did when he ripped up the old shingle as regards the skylight flashing. He should have gone all the way down to the ply, or at least the I+W and the Velux original step flashing should be gone, new I+W and or Flashing tape, then a proper metal roof flashing job, right?

That makes a lot of sense. Given that it takes 3 years or so to get a wind driven rain from SE, once the work is done is it maybe sensible to hit it with a spray of hose water sideways (not highest pressure necessarily, just a nice spray.)? That way we have at least some sense that the fixes worked.

Point taken about the Velux. Still putting a new Velux up on a leaky curb is not smart, so probably fix the curb, i.e. get it flashed or properly sealed out (not just with some caulk) and then put a new curb mount Velux on it. Looks like a VCM 4646 will go up with just a small height difference. Cannot buy a new curb as they do not make the VPL-4 sizing which is 15" inches higher than the skylight....nothing is simple....nothing....

Done that. Just wondered if I now need to educate myself better to ask him the right questions...............so he gets it right this time. Don't like to micromanage a guy but he struck out here in his first at bat.

22 years ago I installed a Velux Skylight (V606) on a 2/12 roof using the VPL-4 curb mount on a 10 year old shingle roof. Built 6' deep beveled light shaft, etc. Went great, no runs no drips no errors even in driving rains. 10 years later the roof had to be replaced, stripped, ice and water shield by commercial roofer. No leaks in rains, UNTIL driving rains out of the southeast brought water into the room from the attic about 3-4" away from the light shaft, i.e. not directly down the shaft. The water then flowed along the ceiling parallel to the shaft. Had roofer come back, did some stuff, all ok.....until the next driving SE rain (fairly rare in my area). Finally I decided to have a standing seam roof done and this is just completed and what do we get but a driving SE rain and lots of water, maybe a quart in various locations, same areas as described above. So, at 2 AM I went in to the attic during the rain (should have done this years ago, I know.) and I see the roof entry point about 6" from the SE side peak, right over one of those Velux curb brackets. The water is running down the adjacent rafter until it hits a drip point then onto the ceiling insulation. Did the leak actually start at that location? Given wind driven, I would guess, but what is the proper way to deal with this? Pull the cladding off the curb completely, re-do the curb to roof join, seal up good with rubber flashing tape, replace cladding? Clearly the two roofers did not get a good join there if this is the originating leak location. Welcome you pro's thinking and appreciate!
