This is a good technique but you lapped your fold the wrong way. Go under with the fold next time so it sheds water correctly. Less chance of trapping water under your bend
Cancel that. I rewatched and seen its just a slight press not a cut. Yours is definitely a better way than mine. I always cut it and folded it but had to use 2 pieces to cover my cut
He did not cut the flashing there, only make an indent. If you see daylight through it after doing that, at a minimum, you must put some sealant in the corner. Better yet, start over.
Do the tin shingle run against the stucco. Chalk a line 3 1/2 or 5 1/2 above shingle surface depending on preference against stucco along tin run. Cut even groove into stucco at least a 1/2 inch deep. Install 1/2 5 or 3 counter flashing into groove. Caulk groove line.
The roofer doesn’t have the same options with stucco as there are with either vinyl or aluminum siding. If the kickout wasn’t in place before the stucco was installed, it’s hard to get it under the stucco.
Or cut 3'' or 4'' up the stucco, ice and water, step flash then put a trim pvc, hardee etc where you cut the stucco. Either that or install a throughwall flashing system then repair the stucco
plus, you didn't counter-flash over the kickout behind the siding. So any water that gets behind the siding, will get behind the kickout too, no? I get that it will pass the inspection, but what is the point on a re-roof with existing siding? I just finished a roof and the inspector wants to see one of these. Don't think the customer is gonna be too thrilled with me cutting into their siding and the look of the kickout either.
If you have to you can. You can also hide your nail with the next tin if you want. The main problem I see with tin runs is when shingles are butted to wall instead of leaving a slight water way along it.
You have to nail the step flashing down. Just not in the lower half. Put two nails in the top furthest corner from the wall and the pressure from the nails should hold it down tight to the shingle below it. Nailing in the top corner prevents a nail being exposed or even being able to come in contact with water if you're step flashing is in the right spot
