ARGGGGG, the back porch transition is leaking when it's raining...AGAIN!...and it's doing it in two places. Looks like I will be removing the entire porch roof this spring.........grrrrrrrr

Sorry to hear that....After your experience with the heater, I noticed my son`s house to be particularly damp when he ran his gas heater (natural gas) It also had a dampish smell in the house Tony

Sorry to hear that Rick. Y'all have a HAPPY NEW YEAR anyway.
hugs, Brandi

Dang.

Maybe the best thing to do is to eliminate the transition. Build up the porch roof side of the transition and run roofing continuous over that out to the porch eave.

Yeah Tony, I will be getting rid of the propane fireplace & mantle....not crazy about it and the moisture it puts out.

Same to you Brandi!

Dave, definitely some kind of a re-design is in order because if I don't fix this it's going to make me loose the rest of my marbles. I think I am going to call in some back-up and get another pair of eyes up there to inspect everything, because I am missing something & it might be something obvious.....or not.

Rick,
Is your transition still the way you pictured it in the attached?

We discussed potential problems of a roof merged that way up here when you first built/photographed it, and your reply was: "that's the way we do it down here."
As I recall your front porch transition was the same. Did it develop any leaks? I don't remember which compass direction your back porch faces.

Sorry for your roof leaking again. I can't begin to imagine the frustration.

I had a porch with a similar looking transition leak on me once. The existing house didn't have a porch, and they wanted it to go out as far as possible. I think I went 12 feet. The house was a 6:12 pitch that was about ten years old, and I built the porch roof with a 1:12 pitch. After a heavy rain, there would be several leaks right at the transition where the flashing was that leaked into the porch area. I went over it inch by inch and couldn't find anything. I ran the hose over each panel right above the flashing and it never leaked. I spent hours out there over several days and could never get it to leak with the hose, but after a heavy rain, it leaked again.

Then I got the idea that maybe it wasn't anything that I had done, and maybe the existing metal roof was leaking. I put the hose at the peak of the roof and let it run. Sure enough, water started coming out at the flashing. What I realized was happening was the rubber gaskets on the existing roof where leaking and had always leaked. The builder put the metal over felt paper, over OSB decking. The water went past the gaskets in the screws, and then under the metal, on top of the felt paper. They had gutters there, so nobody ever knew it was doing anything unusual because the gutters caught all the water.

I replaced the screws in the roof and the problem was solved.

Yes the front developed one leak about half way across & to the right of the front door.

Ron, you may have missed it, but a few months ago I went back and shoved a 50x10" roll flashing under the bottom transition metal on both front and back porches. So this added another 5" to the lower half of the transition, and a no seam one 44' long. After that it rained several times and I had no leaks.....then two weeks ago {poof} two leaks re-appeared on the back(north) porch in the same area of previous leaks.

I went back and re-read the old posts, I saw the above reference, but can't find if or where you illustrated my transition metal is incorrect or the correct way if indeed mine is wrong. My metal guy & the gutter guy even came out and looked at it & said I did it properly.

The whole thing is baffling since I had all leaks stopped only to have some reappear.....



Eddie, you know I have been pondering that very question of a loose screw or two(on the roof not the established one's in my head), or screws that did not have a washer/gasket on them for whatever reason. Assuming that is the problem, why did it go away??...oohhh ohh, pick me pick me{hand raised}.....Warmer temps, roof steel atoms are all fat, lazy & spread out, winter comes and they are freezing their butt's off and huddling together for warmth...opening up a gap that Mr Water exploits???? Hmmmmmmmm................

If there was enough moisture trapped below the metal roofing, freezing weather would cause expansion--perhaps lifting the metal and creating a dimple around the screw head? Then it thaws and the roof metal sinks back down leaving the dimple as a little unsealed trough around the screw head?

I dunno, just thinking about why it stopped then began again.
