Step Flashing Where a Salina Roof Meets a Wall

The dimensions a Salina roof to wall joint has to meet
This is one of the few roof details with numbers you can hold a quote to. Section R905.2.8.3 of the 2025 Residential Code of New York State requires base flashing against a vertical sidewall to be continuous or step flashing, not less than 4 inches high and 4 inches wide, directing water away from the wall onto the roof or into the gutter, with the vertical leg running continuously under the siding, and counterflashing as well where there is anchored masonry veneer. Salina is a town of these junctions: a 1960 median, 68.7 percent single-family detached and 5.6 percent single-family attached across 16,016 homes, which is a great many attached garages and rear additions running into the main house.
What flashing repair involves
Judging the joint before you accept a repair price
Sealant is the tell and you can see it from the driveway. A bead of roof cement or caulk along the line where a roof meets a wall is not maintenance, it is somebody covering a detail that was never built to the dimensions above, and it will reopen. The second tell is the siding itself: where the vertical leg of the flashing does not run up behind the cladding, water gets behind the boards rather than being turned out. A repair that puts it right involves releasing the siding at that junction and setting the pieces in with the courses, which is why the honest quote costs more than the caulking gun and lasts about thirty times longer.
Look for sealant along the junction
A caulked roof to wall line is a covered detail rather than a built one. It tells you what kind of repair was done last time.
Ask where the vertical leg goes
Under the siding, continuously. A flashing fixed over the cladding is outside the requirement and outside the water path it is meant to control.
Add counterflashing at masonry
Where the wall carries anchored masonry veneer the code wants counterflashing as well. On this stock that usually means the garage or the chimney side of the house.

Roof to wall questions from Salina homeowners
The garage roof meets the house wall and the ceiling inside is stained. Is that the roof?
It is far more likely to be that junction than the covering. A garage or addition roof dying into a wall is the classic place for this fault in this town, and the stain usually appears on the ceiling just inside that wall. The fix is at the joint, which is a fraction of the cost of a covering.
How long should a properly built step flashing last?
Longer than the covering around it in most cases, because it is metal weaving through the courses rather than a sealant joint exposed to the weather. That is the whole argument for doing it properly once. What does not last is a surface repair, and the give-away is that it needed doing again within a few winters.
