Hunterdon County is younger than the state. Its median house dates to 1981, and Raritan Township's to 1986. Houses built in the late 1980s or 1990s can still have the roof they were built with, and shingles that old are often close to worn out. On a first roof there may be only one layer to strip, and the deck under it has not been looked at since it went down.
Most of these houses stand on their own. About three homes in four across the county are detached, and in Alexandria, Bethlehem and Franklin Township the share is 97 percent or more. A detached roof often has dormers, valleys and a chimney breaking it up, and each one is a place the new roof has to be tied in tight.
The northern half of the county is in the Highlands, where the State Climatologist puts average snowfall at 40 to 50 inches a year. Snow sits on those roofs longer, and ice can back up at the eaves. Lambertville sits at the other end of the scale: a median house from 1938, and 45 percent of homes attached to the one next door.
A 1986 roof in Raritan Township and a 1938 roof in Lambertville are two different jobs. We get up on yours, look in the attic, and price it after that.
