Roof Repair in Franklin Township, NJ: Somerset, Franklin Park and the Canal Villages

Wrong, and it is the most expensive misunderstanding in Franklin. Even though detached one- and two-family homes no longer need a construction permit to re-roof, the township says all siding and roof replacements in a historic district still require Historic Commission review and approval before the work starts. Franklin’s local districts are bigger than people expect. Every property within 1,000 feet of the D&R Canal is included, along with East Millstone Village, Franklin Park Village, Kingston Village and Middlebush Village. If you live along Canal Road in Griggstown or Blackwells Mills, you are very likely inside one.

How it works: you apply through the Department of Planning and Zoning, which forwards your materials to the Historic Preservation Advisory Commission, a volunteer board, and your project goes on the next open meeting agenda. You generally do not have to contact the commission directly. Bring clear photos of the existing roof, the product you want, and details of any changes to gutters, trim or sheathing.

What the commission cares about shows up in its minutes. On April 7, 2015 it approved replacing a roughly 30-year-old cedar roof on South Middlebush Road with architectural asphalt shingles by a 5-4 vote, but only with the built-in gutters repaired, relined and reused and the original spaced sheathing kept under the new plywood. The same night it unanimously approved an in-kind three-tab replacement on Canal Road in Griggstown, and approved dimensional shingles on the Rutgers Prep Elm Farmhouse over one member’s objection that dimensional shingles are not truly in-kind.

The lesson: in-kind work moves quickly, material changes get debated, and original details like built-in gutters matter. Start early, ask the township whether your property is in a district, and do not let anyone tear off a roof there before approval. We help you assemble photos and product sheets for the application.

Not anymore. If your Franklin Park colonial or southern-subdivision home was built in the 1980s, 1990s or early 2000s and still has its first roof, that roof is at or near the end of its life, whatever the house’s age suggests. Somerset County has the newest housing stock in New Jersey, with a median build year of 1982, and Franklin grew enormously in those decades. That makes it easy to think of these houses as new. Their roofs are not.

Many of the original roofs on homes from that era were three-tab or early architectural shingles installed by production builders, with builder-grade pipe boots, basic ridge vents and sometimes thin ice protection at the eaves. After 20 to 30 summers on a south-facing slope, the asphalt dries out, granules wash into the gutters, tabs curl and the seal strips stop holding in wind.

Here is how to tell. Look for granules piling up at downspout outlets, shingles that look lighter or patchy on the sunny side, tabs lifting along the rakes and ridge, cracked rubber collars around plumbing vents, and dark streaks on the attic sheathing near the eaves. One leak around a boot can be repaired for a few hundred dollars. Several symptoms together mean you are paying for repairs on a roof that is finished.

The good news: a detached house outside the historic districts needs no permit to re-roof, unless we find sheathing to replace. A replacement is also the right moment to fix ventilation and add ice and water shield at the eaves, valleys and around skylights. Our free inspection tells you plainly whether you are in repair territory or replacement territory, with photos, so you can plan instead of reacting to the next storm.

Sometimes it does, often it does not, and in some Franklin communities it depends on whether the problem is the shingles, the flashing or the deck. Franklin has many townhome communities along the Route 27 corridor and elsewhere, plus age-restricted communities such as Canal Walk and Somerset Run with attached homes. Roofs on those rows run continuously from unit to unit, which means one unit’s repair affects the neighbours on both sides.

Start with your governing documents: the master deed, bylaws and any maintenance chart. They define whether the roof is a common element maintained by the association, a limited common element you pay for, or part of your unit. Many associations also require written approval and their own approved contractors, and some require the work to match a community-wide shingle colour.

Then the permit. Townhomes are attached dwellings, so they fall outside the ordinary-maintenance exemption. Replacing roofing on a townhome in Franklin generally needs a construction permit from the township’s Construction Code Department, in addition to association approval. Do not let anyone tell you otherwise because a single-family neighbour re-roofed without one.

Finally, the technical part. When only one section of a row is repaired or replaced, the joints at the party walls are where the next leak starts. New shingles must be woven or stepped properly into the neighbours’ roofs, and fire separation details at the party wall must be respected. We document the condition of adjacent sections with photos before we start, so no one is blamed for damage that was already there, and we give the association a written scope it can approve. Repairs carry our 2-year written workmanship warranty.

Gutters do not cause ice dams and bigger gutters do not cure them. On Franklin’s postwar capes, ranches and split-levels, ice dams come from warm attics melting snow that then refreezes at the cold eave. The Somerset and East Franklin sections around Hamilton Street and Easton Avenue are full of these houses, and many have finished upper rooms or kneewall attics with little insulation and poor airflow.

Here is the mechanism. Heat from the living space leaks into the roof deck. Snow on the upper roof melts, runs down to the overhang, which is outside and cold, and freezes. The ridge of ice grows, and new meltwater pools behind it and works under the shingles. That water shows up as stains along exterior walls, peeling paint at the top of the wall or wet insulation in the kneewall.

Heat cables can keep a channel open, but they treat the symptom and use electricity all winter. Gutter guards and larger gutters do nothing, since the ice forms on the roof itself.

The real fixes, in order of impact: air seal the attic floor and kneewall areas so warm air stops reaching the deck; make sure insulation covers the ceiling evenly; open up soffit vents and pair them with a ridge vent so cold air flows under the deck; and when the roof is replaced, install ice and water shield at least two feet inside the warm wall line. Central Jersey’s freeze-thaw winters, where snow turns to sleet and back, make this more important, not less. We inspect the attic as well as the roof, so the quote addresses the cause instead of just the stained ceiling.

Not on Franklin’s wooded west side, and not on older houses with board sheathing. A falling limb can crack rafters or decking while the shingles above look scuffed at most, and wind can break seal strips without removing a single shingle. Griggstown, Blackwells Mills, the canal and Six Mile Run areas, and much of the Middlebush countryside have mature hardwoods leaning over roofs, and summer thunderstorms and the remnants of tropical storms bring them down.

After a limb strike, look for a dip or wave in the roofline, cracked or sagging boards seen from the attic, nail points pushed through the deck, or light coming through. Inside, watch for new cracks in ceiling drywall or plaster. On older farmhouses with spaced plank sheathing, a cracked board can let the roofing above sag and leak months later.

Wind is subtler. Architectural shingles are held by nails and a factory seal strip. Strong gusts can lift tabs enough to break that seal and drop them back flat. From the ground the roof looks perfect, but those tabs now flap in moderate wind and let water under. Creased shingles show a faint horizontal line across the tab. Insurers generally treat this as sudden wind damage if it is documented soon after the storm.

What to do: after a significant storm, take your own photos from the ground and note the date, then book an inspection. Ours is free and covers the roof surface and the attic side, with dated photos for your adjuster. If there is an opening, request emergency help through our contact page and we will tarp it. Do not climb onto a damaged roof yourself, especially a steep one under wet leaves.
