Roof Replacement Guide
Does a Roof Replacement in a Montclair, NJ Historic District Need Approval?
A roof replacement in a Montclair, NJ local historic district needs a Certificate of Appropriateness from the Historic Preservation Commission when the work alters the exterior appearance. Maintenance and repair of existing roofing with no change in design, scale or appearance doesn't need one. Changing the material or color usually puts you on the commission's agenda.
That last sentence is our reading of the township's rules, and the rest of this guide shows where it comes from. We are Four Seasons Roofing and Construction, a roofer at 38 Speer Ave in Clifton. Our page on roof replacement in Montclair covers the job itself, and the Montclair service area page covers everything else we do in town. This one is only about the historic review.
Is your house in a local historic district?
Check this first, because the Certificate of Appropriateness rules apply to a Local Historic Landmark or a property inside a Local Historic District. The township lists four locally landmarked districts: Town Center, Upper Montclair, Pine Street and Watchung Plaza. It also counts 64 individually designated landmarks.
The same township page also counts 6 National and State Registered Historic Districts, 100 State Register sites and 52 National Register sites. A house can sit on one of those registers without being a local landmark or inside one of the four local districts, and the certificate page is written for the local ones. If you aren't sure which you are, look your address up in the township's Historic Inventory Map, or call the township at 973-509-4955 before anyone orders shingles.
What the township says needs a certificate
Montclair Code section 347-136 is the rule the township cites. For a local landmark or a house in a local district, a Certificate of Appropriateness is required for demolition or construction by addition or alteration, for relocating a structure, for new construction, for new or changed signs and exterior lighting, and for "any change in the exterior elevation or any improvement by addition, alteration or replacement."
A new roof is a replacement. Whether it counts depends on the next list.
What doesn't need one
The same page lists the work that skips the certificate. Interior changes are out. So are changes the public can't see, unless it's relocation or demolition. Then there's "repair or exact replacement of any existing improvement, provided that the work does not alter the exterior appearance," and under it the line that matters for roofs: maintenance and repair of existing roofing materials involving no change in the design, scale or appearance of the structure. Exterior painting is on the exempt list too.
For a roof, then, the size of the job matters less than whether a person walking past would see a different roof afterward.
Where a reroof usually lands
This table is how we read the two lists against common roofing jobs. The township doesn't publish it this way, and the commission's staff has the final word on any address.
| The job | Changes the look? | Our reading |
|---|---|---|
| Patching leaks, replacing damaged shingles to match | No | Repair of existing roofing, on the exempt list |
| Full tear-off, same material and color back on | No, if it truly matches | Close to "exact replacement." Ask staff before you assume |
| Slate off, asphalt shingles on | Yes | A change in appearance, so expect a certificate |
| New color, new profile, or a different ridge or trim detail | Yes | Expect a certificate |
| Adding a dormer, skylight on a street-facing slope, or raising the roof | Yes | An alteration or addition, needs a certificate |
The second row is the gray one. "Exact replacement" is the township's phrase, and a modern architectural shingle in the same color still may not read as exact next to an older roof. If you want the same look, take photos of the old roof up close before tear-off and keep the product sheet for what is going back on.
What goes in the application
Applications are filed with the Department of Planning and Community Development, which staffs the commission. The township's list for every Certificate of Appropriateness application:
- property information, including the zone and the block and lot
- applicant and owner information
- the application fee, plus an escrow fee if one is required, paid to the Township of Montclair
- the applicant's signature and the owner's authorization signature
- photos of the existing condition of the entire building facade, and close-ups of the area of work
The owner signs either way, so even if a contractor fills the form out, you'll see it. Settle in the written estimate who prepares the application, who goes to the hearing, and whether the start date waits for the certificate.
How long to plan for
The commission holds its public hearings once a month, on the fourth Thursday, in the Council Chambers on the first floor of the Municipal Building at 205 Claremont Avenue. Agendas, pending application materials and minutes are posted on the commission's page. We didn't find a published filing deadline before each hearing, so ask the Planning Department how far ahead an application has to be in. With one hearing a month, a roof that needs a certificate has to be booked well ahead of the start date.
One exception from the township's page: if the work is part of an application for development already in front of the Planning Board or the Zoning Board of Adjustment, it doesn't need its own certificate. The commission advises that board instead under section 347-142. Most roof jobs won't be in that spot, but an addition with a new roofline might be.
The certificate is a separate question from the state construction permit. Our post on replacing the roof on a two-family house in North Jersey goes through the state's ordinary maintenance rule for reroofing.
