Roof leak nightmare..... it won't stop


The windows (2) on the dormer) have also been caulked all around them. We had windows replaced also within the last year (leak started over a year ago). Should the window people have done something there? We sprayed around windows with hose and that leaks too!!!! I'm going to scream.
The only thing we haven't had done is the siding - that is from before we moved in. Definitely not in our budget, we are trying to get rid of this house now! ugh

The leak could actually be the fault of the flat roofers who
didn't ensure that their product was properly sealed at that point.
Thank you!! Ok so when Roofer comes tomorrow should I tell him he needs to remove the siding?? What if he says no? The flat roof was done over a year ago (Roofer #1)- and that guy was a complete jerk - stopped returning our calls, etc... he also almost set our attic on fire with his stupid torch.

I'm positive the siding needs to be pulled. Flash the corner and the windows as outlined in my link. See if there is step flashing along that wall. If the wall is OK, remove the caulk so the flashing can work. A real question also, is whether or not, the flashing shoots the water past that corner, or into it.

The first pic is of a leaking corner.
The second pic shows the flashing coming through the corner to keep water out. I had to install a small termination flashing, then the step flashing. That's a downspout to the left cut into the roof line.

The pictures are real close-ups covering about a 5" area, exactly at the corner.

thank you! I will show this to my husband. This seems like something a professional should do though, correct? Would the roofer be responsible or will we need to hire someone else (who does siding?)
I really appreciate everyone's help! So glad I posted here.

It's really the roofer's job, but nearly anybody could follow my tutorial IF there are no serious obstracles such as a lack of step flashing, need of special tools that MAY be required, depending on what is underneath the siding.
Even I find myself needing unforseen things when I open one up.

Like I said earlier, it should have been taken care of properly when that section of roofing was replaced. Although not easy, it is possible to install new step there when installing the roof, especially since the old roof was torn off.

There is no need to remove all the siding to fix it. But the roofing along the wall needs to be removed to do things properly.

Now that the hose test on the window produced the same leak, the siding needs to be stripped.

You have both roofing and siding issues. Your hose test confirmed that. With the type of siding you have water will and does get behind the siding where meets the channel. If the prep work for the siding is done properly that water will run down the moister barrier, over the roof flashing and escape onto the roofing.

If the roof flashing is in place and the barrier behind the siding is done correctly that alone should be water tight and not leak even before the first piece of siding is installed.

It’s been mentioned that “Roofers aren’t Siders”. Unfortunately that works both ways and is the truth to often. You need more than a just a roofer with a siding tutorial though . There are people good at both and that’s who you need. It’s not rocket science we’re both fighting the same rain drop.

I will say this as I mentioned before, post here with your newest roofers recommendations before you write a check.

Good luck.

You missed an important part. With the proper flashing in place, the water will never reach the moisture barrier. It should be kept from it at all costs. That's like depending on the roof felt to keep the water out.

I really feel for you here and its nice to see you trying to correct
these leaks properly before selling the house.

It's really hard to say exactly what is causing either leak without a
physical inspection and some history as to when the leaks developed
under the window.

If there was no leaking at the window area till after the window
installation,you need to have the details of that install looked over
closely.
It may have been leaking before the new window was installed but
could have run out over the top of the old flashing onto that lower
roof.All this means is that there was some kind of moisture barrier
under the siding doing its job.

From the looks of the age of that siding.I'd guess it was either just
a fan fold leveling board or plain old rolled foil.
Both of these could be well past their usefulness or are compromised.

Another possibility,if the leak under the window developed after
the lower roof was done,is that the top of that new roofing is now
over the top of any existing moisture barrier/leveling board ,and
allowing water that gets in around the window to get under the new
roofing.

If you knew when this leak started,it may narrow the problem down
some,but without seeing it personally,I'm just trying to give you a
few things to be aware of once you start talking to your roofer.

Edit:Detail of the window trim and sill areas would help a lot finding
any potential leaks.

No, I completely get the important part and couldnít agree with you more that water should never reach the moister barrier but how do you keep water from getting behind the vinyl/aluminum siding where it meets the j-channel? Where does that water go? It hitís the mb (hopefully) and runs down the wall and over the flashing.

And yes if the roofing fails or is damaged Iíd hope your felt/flashing job would keep the water out. At least long enough to correct the issue.

Oh ron, don't get tinner and I started on our opinion of underlayments and myths about them.

Well then I will respectfully retract paragraph B but stand firm on A.

I’m no roofer (as you well know) and would never even think of debating the products of your trade.

Oh I wasn't trying to start anything Ron, no worries. We are just of the opinion that underlayments are overrated. They have their place but too many people nowadays actually depend on them to keep the weather out. But that's a subject for a different thread.

Roof leak nightmare..... it won't stop


Ok, so the roofer came tonight and was very helpful - I do give him credit for coming out here at 8pm, we are out of town for him. Yes he did replace all the step flashing when he did the roof. We showed him where the problem was as we determined with hose and he concluded that the problem was the corner piece (sorry I don't know the proper terms) of the siding was supposed to have 1/2" clearance above the roof, but it was right on the roof. He said this was preventing the water running down the J-channel to escape. He cut off a piece at the bottom right there, and behind it was loads of gunk (tree seeds, etc.) and big hunks of caulk - not from us). After he did this, he took a big cup of water and poured it at the top of the J-channel up by the peak. Some was diverted by the caulk lower down (which my husband added to yesterday, we see now why this was a bad idea), and the rest of the water ran behind the caulk and flowed out of the hole he cut onto the roof below. Nothing dripped into the closet.

He is coming back this week to insert a piece of metal (flashing?) into this spot at the corner, I think he said it will go under the step-flashing to ensure that the water will run out of the J-channel freely and not be dammed up anymore.

Does this sound right? It made sense when he explained it, and he seemed pretty certain this was the problem we have had all along.
