Snow load
How do Passaic County winters change the roof design?
They raise the snow numbers. DCA Bulletin 19-1 lists a 40 psf fallback ground snow load for Passaic, second only to Sussex among the values it gives.
That fallback applies only when an ASCE 7 hazard tool returns a case-study result for the address. Otherwise the designer uses the tool’s site-specific value, which can climb with elevation in the northern towns.
Passaic falls inside the State Climatologist’s northern zone, where snowfall averages 40 to 50 inches a year, against 10 to 15 inches in the state’s extreme south (Office of the New Jersey State Climatologist). Energy code places the county in zone 5A (DCA Bulletin 22-1).
Snow guards and ice at the eaves
Snow can leave a metal roof in one sheet, so we place snow guards above entries, walks and driveways. S-5!, a maker of seam clamps, says its clamps hold snow guards on standing seams without piercing the roof.
DCA Bulletin 07-3 makes the ice barrier a code requirement only in Sussex County. Even so, every metal roof we install in Passaic gets a self-adhered membrane at the eaves as standard practice.
Roof systems
Which metal roof fits a Passaic County house?
Standing seam for most main roofs, metal shingles where a traditional look matters, and a mechanically seamed panel for low-slope sections.
Some older city houses have a shallow rear roof or porch roof. The model residential code allows standing seam down to 1/4 inch per foot, but many panel makers set higher minimums (model code text).
Sheffield Metals, for example, rates its snap-lock profiles to 2/12. Its 1.5-inch mechanical seam is rated to 2/12, or 1/12 for steel with inseam sealant, depending on project conditions (Sheffield Metals). The installation instructions for the chosen panel are the final word on slope.
- Standing seam for main roofs and, with the right seam, shallow rear sections
- Metal shingles for houses on streets of slate and shake
- Roof repair when a leak needs fixing before a full replacement makes sense
- Asphalt shingles for owners who want to stay with shingles
Two-family and rental homes
What changes when the house has two or more units?
Permits, mainly. A detached two-family house is treated like a single-family one, but a three-family house or larger building generally needs a permit for a new roof.
New Jersey’s Uniform Construction Code counts re-roofing a detached one- or two-family home, and re-siding a one- or two-family home, as ordinary maintenance (N.J.A.C. 5:23-2.7). Multifamily and attached buildings are not on that list. For them, like-for-like siding is ordinary maintenance only until it reaches a quarter of the total exterior wall area.
Your town’s construction office, not the county, issues any permit and decides what needs one.
The state’s home improvement law covers single- and multi-unit residential buildings alike. Any job over $500 needs a written contract signed by all parties, and the homeowner can cancel until midnight of the third business day after receiving a copy (P.L.2023, c.237). Our guide to home improvement contract rights covers the details.

A 53.1 percent owner-occupied rate means nearly half of the county’s occupied homes are rented. If you own one and live elsewhere, we can schedule the measuring visit around your tenants.
Lead-safe work and windows
What do older Passaic County homes need for windows and trim?
Lead-safe practices on any house built before 1978, and windows rated for ENERGY STAR’s Northern zone.
EPA’s RRP rule covers window replacement in pre-1978 homes regardless of how many windows are involved. Other paint work counts as exempt minor repair only when it stays within six square feet per room indoors or 20 square feet on the exterior.
New Jersey’s Rehabilitation Subcode adds limits of its own on those older homes, such as no power sanding without a HEPA vacuum attachment and no heat guns above 1,100 degrees F (N.J.A.C. 5:23-6.4). Testing that finds the paint lead-free lifts those limits.
Windows for the Northern zone
ENERGY STAR’s Northern zone covers Passaic and asks for a U-factor of 0.22 or lower (ENERGY STAR). Our pages on window replacement and triple-pane windows compare the options.
If new windows fog on the room side in January, the cause is usually indoor humidity, not the glass. Andersen suggests keeping winter humidity at 30 to 35 percent or less. Fog between the panes is different: Natural Resources Canada says it means the seal has failed and the sealed unit needs replacing.
Gutters and siding
Which gutters and guards hold up in a Passaic County winter?
Seamless gutters with a guard that sheds snow well. This Old House does not recommend reverse-curve helmets where snow and ice build up.
In its review, This Old House rates micro-mesh guards highly effective against debris of every size but hard to fit well. It also found that no guard type is maintenance-free, which matters under heavy tree cover in the northern towns.
HomeGuide’s 2026 guide puts professionally installed gutters at $12 to $25 per linear foot nationally, or about $2,200 to $5,000 for an average home (HomeGuide). Your exact price comes from a free measurement of the gutter runs. Compare seamless gutters and gutter guards.
For the walls, our siding page compares vinyl, fiber cement and seamless steel siding. Rotted fascia or tired soffit can be handled in the same visit through our soffit and fascia service.

Passaic County roofing questions
Does re-roofing a two-family house in Passaic County need a permit?
Not if the house is detached. New Jersey treats a new roof covering on a detached one- or two-family home as ordinary maintenance. Three-family and larger buildings, and attached homes, generally need a permit from your municipal construction office.
What snow load is used for a Passaic County metal roof?
Passaic’s fallback in NJ DCA Bulletin 19-1 is 40 psf, second only to Sussex. That number is a backstop: the designer first looks up your address in an ASCE 7 hazard tool, and higher ground in towns like West Milford can raise the result.
Can standing seam go on the low-slope rear roof of my Passaic County house?
Often, if the slope meets the panel maker’s minimum. Code allows standing seam down to 1/4 inch per foot, but manufacturers set their own limits; Sheffield Metals rates one mechanical seam profile to 1/12 for steel with inseam sealant.
I rent out an older Passaic County house. Do lead rules apply to new windows?
Yes, if it was built before 1978. EPA’s RRP rule covers window replacement in those homes no matter how small the job, and the work must follow lead-safe practices.
Which gutter guards suit Passaic County winters?
Guards that do not trap snow and ice. This Old House does not recommend reverse-curve helmets where snow and ice build up, and it rates micro-mesh highly for debris; every type still needs some upkeep.
