Roof Penetration and Leak Diagnosis in Camillus
A Camillus roof that starts dripping beside a vent pipe has not worn out, it has one joint that failed while the covering all around it is still sound. 59.9 percent of the town's 11,481 homes were built between 1950 and 1979, the tightest single-generation concentration in the county, so whole streets here arrive at that point together and a finding on one house is worth checking on the next.

Section R905.2.8.4 of the 2025 Residential Code of New York State does not set dimensions for soil stack, vent pipe and chimney flashing. It requires instead that they be applied in accordance with the asphalt shingle manufacturer's printed instructions, and R905.2.8 makes the whole flashing section subject to those instructions.

No primary source was found for the service life of a plumbing vent pipe boot or its rubber collar. Section R905.2.8.4 of the 2025 Residential Code of New York State defers pipe flashing entirely to the shingle manufacturer's printed instructions and states no durability figure, and no federal or state publication reviewed gives one.

Section R903.2.1 of the 2025 Residential Code of New York State requires flashings at wall and roof intersections, wherever there is a change in roof slope or direction, and around roof openings, and requires a flashing to divert water away from the point where the eave of a sloped roof meets a vertical sidewall. Where the flashing is metal it must be corrosion resistant and not less than 0.019 inch thick, which is No. 26 galvanized sheet.

Why Camillus roofs let go at the pipes, not the field
At the penetrations the New York code does something unusual: it sets no dimensions at all for soil stack, vent pipe and chimney flashing, and requires instead that they be applied in accordance with the asphalt shingle manufacturer's printed instructions, with the whole flashing section made subject to those instructions. That has two consequences worth knowing before you accept a quote. The first is that you are entitled to ask which product is on your roof and what its instructions require, because that document is the standard the work is measured against. The second is that no rule of thumb about how long a boot lasts is a code rule, and we will not hand you one: there is no primary source anywhere for the service life of a pipe boot or its rubber collar, so the argument is made from what is visible on the roof and from the way the code is built, never from a number of years. Camillus is where this gets practical. 59.9 percent of the town's housing went up between 1950 and 1979 and 69.1 percent of it before 1980, with 78.7 percent single-family detached, which means near-identical roof geometry in long runs and details that were all done the same way at the same time. Camillus village inside the town is a different stock, a 1958 median with 32.2 percent built before 1940 and only 44.2 percent detached, so we say which of the two we mean.
