Lebanon Borough is one of Hunterdon County's smallest municipalities — a compact community near the Route 22 corridor, entirely distinct from the much larger Lebanon Township to its northwest.
Its scale means the borough's housing is relatively consistent in age and type, and roofing issues here tend to be the straightforward ones: coverings reaching the end of their life, flashing details that were never quite right, and ventilation that was never balanced.
Lebanon Borough covers a very small area of eastern Hunterdon County beside the Route 22 corridor, surrounded by Clinton and Readington townships. It is a compact residential community rather than a dispersed rural municipality.

Local Building Stock
The borough's housing is a mix of older village houses on small lots with steep plank-decked roofs, and twentieth-century construction with more conventional framing and plywood decking. Lot sizes are modest throughout, and roof footprints are generally simple, with detached garages common.
Lebanon Borough work is mostly replacement on ageing coverings, flashing and eave repairs, and inspections for homeowners planning ahead.
Seasonal Conditions
The borough sits on relatively level ground away from the county's exposed ridges, so wind loading is moderate. The region's freeze-thaw cycling is the main winter factor, and ice at the eaves is most pronounced on houses where attic heat loss keeps the upper roof warmer than the overhang.
Across the region, winter cycles repeatedly above and below freezing rather than staying frozen. Water works into small gaps, freezes, expands and enlarges them — which is what wears at flashing joints and builds ice at the eaves.
Services
The full range is available here. These are the ones most often needed on local properties.
Targeted repairs for leaks, wind-lifted shingles, failed flashing and damaged roof penetrations.
Full tear-off and rebuild of the roofing system, from decking and underlayment through to ridge ventilation.
Urgent response for active leaks, storm-opened roofs and exposed decking, starting with stopping water entry.
Roofing for houses across Hunterdon County, from mid-century colonials to farmhouses and newer developments.
Low-slope and steep-slope roofing for commercial, retail, light industrial and multi-unit properties.
If your roof is open or actively leaking in Lebanon, call (914) 906-5748 rather than waiting on a form, so we can treat it as urgent.
Our Process
The same sequence on every property, whatever the municipality.
Tell us what you are seeing — a stain, a missing shingle, a roof you know is old. Photographs help if you have them.
We assess the roof surface and, where access allows, the attic side, so the diagnosis is based on where water is actually travelling.
A plain explanation of what we found and why it matters, including an honest view on whether repair or replacement is the better use of your money.
Scope, materials and price in writing before any work begins, so you know exactly what is included.
Carried out with the property protected. Failed components are removed and rebuilt rather than covered over, and we talk to you before any scope changes.
Debris cleared, a magnetic sweep for nails, and a review of what was done and what the work revealed.

Questions
No — they are separate municipalities. Lebanon Borough is a small community near Route 22; Lebanon Township is a much larger, hilly and wooded municipality to the northwest. We serve both, but the roofing conditions in each are quite different.
Check whether air can enter as well as leave. A ridge vent does very little if the soffit intake is blocked by insulation. Signs of a problem include frost on the underside of the sheathing in winter, a very hot attic in summer, and recurring ice at the eaves.
Architectural asphalt shingles commonly give somewhere around twenty to thirty years in this climate, but ventilation, slope orientation and installation quality shift that considerably. An inspection will tell you where yours actually stands rather than relying on the age alone.
Yes. We work across all 26 municipalities in Hunterdon County, from the Delaware River boroughs through the central farmland to the northern uplands.
