Best Fix for a little sealant delamination Front Cap

That metal strip appears to be lifting also. Something wrong there and needs to be addressed immediately. Remove the caulk, clean everything and examine why that strip is lifting up or the roof is flexing down. Most likely some rot in there. Use Sikaflex (follow the directions carefully) it's supposedly better than Dicor. Finish with Eternabond and seal the edges of the Eternabond with sealant.
