Improper installation along rake

I have a fairly simple single pitched roof, however the rake jogs in at a few locations. Instead of creating 2 custom panels to accommodate the jog, the roofers simply cut into the panel. I see water come out from under the facia trim piece and am sure that this means I could potentially have water getting under the roof here.

Is there a way (without peeling back the rest of the roof) to either replace or lay on to of this single panel with two narrower panels so that there is a panel edge along this portion of the rake?

Alternatively, is there a way to simply put an upside down u piece to prevent water from entering into that panel altogether and prevent the potential leak?

Thank you both for taking the time to try to help and for your replies.

Robin, thank goodness you recommended removing the trim cap. Such a simple suggestion but not something I had physically done myself. I have been trusting professionals and had multiple roofing companies look at this roof since it went up because there are very apparent workmanship issues (over/under/mis-driven fasteners) that anyone who sees mentions immediately. 2 of the roofing companies said this particular issue was unrepairable and would require a complete re-roof. The third vendor originally said the same thing, then recommended coating the roof while offering no warranty and after I suggested diverting the water from that channel was at least willing to work with me. They wanted $20k+ to fix the issue and I was very close to signing.

Today, when I removed the trim cap I found a situation that was much better than what was described to me and I am quite happy I took your advice.

Apparently, the original roofer had bent up a new leg to keep the water in the channel.

Upstream where the channel was cut in, at the corner, they had created a dam that is highly reliant on some sealant (I believe Sika). The sealant runs down the trim along the top of roof panel about a foot and then the gap gets sizable. I found there was a small pile of leaves that was stuck under the trim and I think the water I saw sneaking out from under the trim piece was due to those leaves.

I think the task of resolving this should be much simpler now that it is known there is a vertical leg bent up on the side of that panel where the roofer cut in.

For information sake, The roof does not have peel and stick under it (a bait and switch in the contract) so I would like to do whatever possible to keep water from getting under the aluminum.

I am curious if you would recommend the addition of anything to this rake edge? Would an additional piece of flashing make sense in this scenario to keep any potential water from sneaking under the AL?

Also, the use of Sika for the damn is clearly not working at the top and is allowing water to sneak out the corner of the facia behind the gutter. Everywhere they used Sika (including trim caps) it cracked within 2 years, most likely from the strong UV component here in Hawaii. Are there tapes or sealants with embedded mesh that can be used to stop water there? Roof is Durapon 70. What about running some the length of trim where it touches top of panel to stop the leaves from sneaking under and causing a log jam?

Thank you again for any and all recommendations. I really need a strong game plan for this as all the local contractors I’ve dealt with are either taking me for a ride or not aware of how to solve.

Alternatively to trying to seal things off from getting under the trim cap, perhaps it would be better to open things up more to allow debris to not get caught in the first place and not severely reduce flow of the panel.

What about having a new piece of trim cap made that isn’t so wide and more importantly doesn’t come down so closely to the panel?

Top sketch is of the current cap and the lower sketch would be of the proposed trim.

Thanks so much for the responses Robin. Really, it’s great to get your input.

I’m going to see if I can get a piece made like what I drew. In the meantime I am thinking of mounting a length of AL screen to the back of the current trim with some butyl tape and letting it extend onto the roof panel.

That way it should allow water to continue to pass onto that portion of panel (which should be fine) while eliminating the concern of leaves causing a log jam.

Agreed, I’m trying to keep sealant use to a minimum. I think the only place I may require it is at the corner (uphill) where they cut in to the panel. Currently the portion of the panel that is over the gutter has a leg bent up and then they used sika to bridge to the trim cap. I’m assuming this was to keep water from sneaking around into the very corner where the vertical bend starts. Unfortunately I can’t think of a trim detail that would resolve that location, so it sounds like the Wakaflex product you referenced would at least be a better match for that application.

Thank you so much! You seriously made a huge positive impact for my family by keeping me from spending an exorbitant amount of money on something that just didn’t need it.
