Head flashing repair on cement tile roof
Hi,
I have to replace an area of roofing felt that was damaged. Also, when removing the roof tiles the lead flashing cracked in a few places. What is the procedure for replacing the felt and flashing as shown below. I can get my hand between the stucco wall and osb but obviously I'm not going to be putting any nails in above the stucco edge. My vertical OSB does not extend down to the roof- I can see framing between stucco edge and roof line but of course I could install a strip of OSB as a nailer. The distanced between stucco edge and roof is about 6".
I don't have the optional flashing.
Thanks

Not sure about your statement regarding the fact that you can get your hand in between the stucco and the sheathing. This would imply the stucco reinforcement mesh was nailed on over furring strips .
Typically the combination of lead's weight and malleability are enough to keep it in place without nailing. You could spot adhere it with a polyurethane construction adhesive to the sheathing. I don't think doing a thin strip of osb as any type of nailer is a viable idea as the material does not lend itself to that type of use, it will snap.
If you want to seal the gap, use a foam sealant . The sheathing should, of course, have a covering of felt paper or a self adhering type membrane that is carried up the wall as far as you can reasonably work it.
