Diagnosing a Leak on a Camillus Roof
Nobody can tell you how many years a shingle lasts here, because no publisher states a figure, so the age of your roof is not an answer.

What is and is not published about a roof's lifespan
In the Town of Camillus the median year of construction is 1966. Of 11,481 housing units, 6.1 percent were built in 1939 or earlier, 9.2 percent before 1950, 69.1 percent before 1980 and 30.9 percent in 1980 or later. 78.7 percent are single-family detached and 79.4 percent of occupied units are owner occupied.

No primary source was found for a local asphalt shingle service life figure. Neither NOAA, the Census, the Department of Energy Building America Solution Center, the Residential Code of New York State nor the Energy Conservation Construction Code of New York State publishes a shingle life expectancy for this climate, and the Residential Code sets performance and material standards without stating a service life anywhere in Chapter 9.

Why the age of a Camillus roof proves nothing on its own
The most common sentence in this trade has no source behind it. We went looking for a local service life figure for asphalt shingles and found none: not from NOAA, not from the Census, not from the Department of Energy's building guidance, and not in the Residential Code of New York State, which sets performance and material standards through its whole roofing chapter without stating a service life anywhere. So when somebody tells you a roof of a certain age is due, that is an opinion wearing a number. It matters in Camillus because the town's housing arrived together: 59.9 percent of its 11,481 homes were built between 1950 and 1979, which makes age the easiest thing to point at and the least informative.
What to ask instead of how old the roof is
Replace the age question with three better ones. Where exactly is the water arriving, which is answerable by looking rather than estimating. What is the condition of the deck under it, which decides how urgent anything is. And has this happened before in the same place, because a repeat in one spot is a detail that was misdiagnosed rather than a covering that has worn out. On a town's worth of houses built to a similar pattern in a similar decade, those three answers will differ from house to house even where the build year does not, and they are the ones that change what you should spend.
Ask for the entry point, not the age
A named location on the roof is checkable. A service life figure for shingles in this climate is not published by anyone and should not be driving your decision.
Get the deck condition described
What the sheathing is doing under the covering is the thing that decides urgency, and it is visible from inside on most houses in this town.
Treat a repeat leak as a misdiagnosis
Water coming back to the same spot after a repair usually means the wrong thing was fixed, not that the work was poor.
Tell us where the water actually shows
Which room, which corner, and how often. We arrange an insured contractor who names the entry point rather than the age.

Leak questions Camillus homeowners ask
Three neighbors have had roofs done. Does that mean mine is due?
It means the street was built at once, which is true of most of this town. It does not tell you what is happening on your roof. The houses went up together, and they have had different amounts of sun, different penetrations added, different attic conditions and different repairs since. Look at yours before drawing a conclusion from theirs.
If you cannot say how long shingles last, how do I plan?
By condition rather than by calendar. What we can tell you is what the covering looks like now, what the deck underneath is doing, whether the joints are sound and what is likely to need attention in the next couple of years. That is a plan built on your own roof rather than on a number nobody publishes.
Get a diagnosis instead of a date
Send the Camillus address and a photo of the stain. No obligation, and the covering may have years left in it.
