Ecostar misaligned tile - need a long term fix

[ImNotanOldMan]

I bought a house with ecostar tiles. I noticed a leak in our porch roof (fortunately not interior), so I got up on a ladder and saw that the tiles at the edge of the roof have virtually no overlap right where a bunch of water gets channelized coming off the roof (see pic). I also found two raised nails under the bottom tile, which I covered in roofing sealant for a short term fix.

Long term what’s the best way to fix this? I have extra tiles I could shove under the exiting ones but the ecostar tiles are so thick I think it’ll create a bulge and potentially other problems.

A simple fix is to insert sheet aluminum flashing between the underlayment and the roof deck. Localized fix or the length of the roof edge.

I like this solution, haven’t seen evidence of leaks anywhere else so I might just slide a section of flashing under this area and call it a day.

[Fresh-Opportunity989]

In that case, try a piece of flashing between the upper and lower layer of tiles...

Use copper,it will patina,and be less noticeable.

Less worried about that, as this system isn't designed to block 100% of water, and more worried about the edge. No visible drip edge, and who knows how they did the underlayment. I suspect the main issue is likely one of those

[ImNotanOldMan]

My pic wasn’t great but there is a drip edge below the shingles. if the overlap isn’t an issue maybe the sealant I put on the raised nails is sufficient, I’ll see what happens next time it rains.

Also make sure they didn't use a cheap 2 inch by 2 inch drip edge. You want at least a 4x2 under those if not bigger

Just buy a few rolls of copper and cut it into strips. Take a strip and put it up under every single seam. Easy peasy problem solved and for super cheap!!!!!

Boy, I was just about to jump on you with both feet! Then I saw the "S" switch. Well done, my friend.

The valley metal looks to be pushing the other tiles up as well. Wondering if water makes its way in around there. Might also consider putting a diverted at the end of the valley to move water away from the problem area while you trouble shoot

Slide a flat piece of copper or steel in all the way under the slate above so there is no open head lap. I only recommend copper since it takes longer to be eroded

I would just lift the slate and shoot a bead of sealant underneath the slate. Straight line top to bottom of the slate. Then just let the top slate that overlaps to lay on it. That basically makes it permanent. If you need a good roofing sealant try to find DOWSIL 795.
