Roofing in Hillsborough
Hillsborough is the largest township in Somerset County by land area, and for most of its history it was farmland — colonial-era farmsteads and orchards spread across the broad valley between the Raritan and the Millstone. That changed fast. The township went from fewer than eight thousand residents in 1960 to more than forty thousand today, and the fields around Belle Mead, Flagtown, and Neshanic filled in with subdivisions over a single generation. The result is a town where a hand-framed farmhouse from the 1800s can sit two lots down from a 1990s colonial, and both roofs land on our list for very different reasons.
The land itself sets up the roofing problems. From the low, wet ground near Royce Brook the township climbs toward the Sourland Mountain ridge on its southwestern edge — a hard band of diabase traprock that rises out of the farm fields and holds onto shade, wind, and snow longer than the flats do. Homes up against the wooded ridge sit under a steady drop of leaves and needles that pack into open valleys and slow the drainage off north-facing slopes. Down in the developments the trouble is shape: the large colonials that went up in the 1980s and 1990s carry attached garages, bump-outs, and front porticos, and each addition ties back into the main roof at a valley or roof-to-wall seam that has to be flashed right.
The older stock asks for a different eye. Farmhouses out here were rarely built all at once — a kitchen ell, a back porch, a dormered second floor got added across decades, so the roof is a patchwork of planes meeting at different pitches, with a low-slope porch or sunroom roof tucked under a steep main gable. Those junctions are where water finds its way in, usually long before the shingles themselves are worn out. Our approach is to pin down which part is actually failing — a cracked pipe boot, a rusted valley, a chimney with no cricket behind it — and fix that, rather than sell a whole new roof to solve a two-foot problem.
Why Hillsborough roofs vary so much block to block
The large colonials that define the newer developments tend to share a weak point: ventilation. Many were built with cathedral or tray ceilings and vaulted foyers that leave little room for a proper intake-to-ridge airflow, so heat and moisture stall in the deck. On a north-facing slope in the shade of the Sourland treeline, that trapped warmth is exactly what melts snow into an ice dam that builds along the eave, then refreezes and pushes water back under the shingles. We check that a continuous run of ice-and-water shield actually reaches past the interior wall line, and that the intake venting at the soffit hasn't been painted or insulated shut.
Chimneys are their own chapter here. The farmhouses and older colonials often carry wide masonry chimneys, and a broad chimney left without a cricket on its uphill side lets snowmelt and leaf litter pile against the brick until the flashing gives up. We look at whether the step flashing actually laps under each shingle course and ties into a counter-flashing set into the mortar joints; the failure we find most often is a gap bridged with a bead of caulk. On the newer homes the same logic covers the roof-to-wall runs where an attached garage or two-story bump-out meets the main roof, plus the kick-out flashing that keeps water moving into the gutter and off the siding.
Somerset County Weather & Wear
Somerset is hilly enough to get heavier wet snow than the coastal counties; high-pitch roofs here need full ice-and-water-shield coverage at eaves and valleys.

Common Hillsborough Roof Problems We Fix
Patterns we see again and again on Hillsborough roofs — most driven by the local housing stock and Somerset County climate. If any of these sound familiar, give us a call for a free on-site assessment.
- Homes along the Sourland Mountain edge sit under heavy tree cover and hold snow on their north slopes, so ice-and-water shield coverage at the eaves and a clear intake-to-ridge vent path matter more here than on the open flats.
- Wooded lots near Royce Brook and the ridge drop leaves and needles into open valleys year-round; a metal valley liner sheds that debris far better than a shingle-woven valley that traps it and rots the deck underneath.
- Older Belle Mead and Neshanic farmhouses grew by additions — ells, dormers, tacked-on porches — leaving a roof of mismatched pitches whose valleys and roof-to-wall seams leak long before the shingles wear out.
- The 1980s-and-later colonials in the subdivisions often trap heat under cathedral and tray ceilings, cooking the shingles from below and shortening the life of the roof unless the soffit intake and ridge exhaust are opened up.
- Wide brick chimneys on the older houses were frequently set without a cricket on the uphill side, so leaves and snowmelt dam behind them and the step and counter-flashing carry more water than they were built to handle.
