Hello - I recently had to cut out and replace a badly corroded section of my metal ribbed roof panel up under the ridge of an old pole barn. Unfortunately, I was unable to find a similar profiled panel as the already existing roof, and therefore the new "patch" does not overlay perfectly. As you can in the pictures, the is a gap on the end of the patched piece in the spots where the contours don't match.
So far I haven't noticed any leaks, but I am afraid that when we get a strong wind driven rain storm that it will push water up under this gap (between the new and old sections) and leak down from the ridge area. Is there anything I could use to fill in these voids? It's too big of an area to caulk so I'm looking for other suggestions. Again ideally I would have rather purchased a panel with the same profile but I haven't been able to find one.
