Sussex County roofs
What we see on Sussex County roofs
Sussex County is mostly single-family homes owned by the people who live in them. Census data puts 79% of homes as single-family detached houses, the highest share of the 11 counties we serve, and 82% as owner-occupied. The median home was built in 1975. The county is also the highest ground in the state: the U.S. Geological Survey lists High Point, in Sussex County, at 1,803 feet, New Jersey’s highest elevation. Height, snow and trees shape almost every roof job here, and so does the distance from our office, which is why we plan Sussex jobs further ahead than jobs closer to home.
Snow, ice dams and a shorter working season
Rutgers’ Office of the New Jersey State Climatologist describes the state’s northern climate zone, the highlands and valleys of the north, as colder than the rest of New Jersey, with annual snowfall averaging 40 to 50 inches and the shortest growing season in the state. Snow that sits on a roof for weeks, melts over a warm attic and refreezes at the colder eaves builds ice dams, and the water backing up behind them is a classic cause of winter leaks.
Every roof we replace gets ice & water shield along the eaves and in the valleys, and on the snowiest houses we carry it further up the roof. We balance intake vents at the eaves with ridge venting so the deck stays cold. Shingles also need warm days to seal down properly, so full replacements are best planned from spring to fall. A winter repair is still possible, but we tell you when a patch is temporary until the weather allows a permanent fix.
- Thick icicles hanging from the gutters or the edge of the roof
- A ridge of ice built up behind the gutters after a few cold days
- Water stains on ceilings or walls near the outside walls after a thaw
- Frost or damp spots on the underside of the roof deck in the attic
Wooded lots: branches, moss and gutters
Many Sussex homes sit among tall trees. Shade keeps a roof damp, and on the north side that dampness grows moss and lichen that lift shingle edges and hold water against the roof. Branches rubbing on a roof wear the granules off, and falling limbs crack shingles and dent gutters. Leaves and needles fill valleys and gutters, and a gutter packed with debris in December is where an ice dam starts. If the house is heated with a wood stove or fireplace, the chimney sees heavy use all winter, and its flashing, crown and mortar take more wear than a chimney that is rarely lit.
Before a replacement, we point out branches that should be cut back, and we recommend shingles with algae resistance for shaded roofs. On a repair, we clear the valleys and check for soft spots under any moss before we decide whether the area can be patched or needs new decking. On a new roof we install drip edge and a gutter apron so water coming off the shingles lands in the gutter instead of running behind it and rotting the fascia board.
Lake homes, long driveways and access
Lake Hopatcong, New Jersey’s largest lake, sits on the border of Sussex and Morris counties, with Hopatcong and Byram on the Sussex side. The state’s Division of Fish and Wildlife notes that it was once a summer vacation destination and now serves as a year-round home for thousands of residents. Lake houses that started as seasonal cottages often have shallow roofs, porch roofs and additions from different decades, and the low-slope sections need a membrane such as EPDM rather than shingles. Those cottages also tend to have little attic space, so we choose vents that fit the framing and tell you plainly how much ventilation the house can take.
Steep gravel driveways, narrow lake roads and homes set far back from the street are common across the county. We look at access during the estimate and decide where the dumpster and materials can go without damaging the driveway or the lawn. On a hard-to-reach house that planning matters as much as the roof itself. We tarp the house and the landscaping during the tear-off and run a magnet sweep for nails across the driveway and lawn before we leave.
A roof for the long run, and how we schedule Sussex jobs
With most Sussex homes owner-occupied, many owners will live under a new roof for decades. That is a reason to do the roof once and do it fully: a tear-off to the deck instead of a second layer, new flashing at the chimney and sidewalls instead of reused metal, and ventilation sized for the attic. New Jersey building rules also limit how many layers a roof can carry, and a second layer hides rot in the deck. For the shingles themselves, we install architectural shingles from GAF or Owens Corning, which are heavier than older three-tab shingles and hold up better to wind. The written estimate lists every layer we install, from the underlayment and ice & water shield to the ridge cap, so you can compare quotes line by line.
Our crew drives about 34 miles from Elmwood Park to Newton, so Sussex jobs are scheduled ahead rather than squeezed in. Our line is answered 24/7 at (201) 397-0232 for active leaks. Each Sussex town’s construction office decides what needs a permit; when your job needs one, we file it and arrange the inspection. If water is coming in while you wait for us, catch it in a bucket, move belongings away from the leak and stay off a snowy or icy roof.
