What Is Historic Roof Restoration?
Historic roof restoration repairs deteriorated original roofing on a period building rather than replacing it, and matches any necessary replacement to the old roof in design, color, texture, and, where possible, material. It covers slate, clay tile, wood shingle, and historic metal roofs.
What Historic Roof Restoration Do We Provide?
Newark Quality Roofing restores 4 historic roof materials across Essex County: natural slate, clay and terra-cotta tile, wood and cedar shingle, and historic metal — standing-seam and flat-seam terne and copper — on residential and commercial landmarks. Historic roof restoration repairs deteriorated original roofing rather than replacing it, and matches any necessary replacement to the old roof in design, color, texture, and, where possible, material, per the Secretary of the Interior's Standards for Rehabilitation, Standard 6.
A Newark Quality Roofing historic restoration retains the roof shape and the character-defining features — dormers, decorative cresting, finials, and snow guards — because the roof shape and detailing are essential elements of a historic building's character, per NPS Preservation Brief 4. Newark Quality Roofing documents the existing roof first, photographing, measuring, and recording the patterning, coursing, and material dimensions, then matches in-kind samples before full installation, per NPS Preservation Briefs 4, 19, 29, and 30. Newark Quality Roofing works within the Secretary of the Interior's Standards and coordinates with the owner's architect, the municipal Historic Preservation Commission, and the NJ DEP Historic Preservation Office, rather than determining historic status.
- Historic slate roof restoration — Historic slate roof restoration repairs and replaces individual slates with non-ferrous fasteners — solid copper or stainless steel — and slate hooks, never plain or galvanized steel, because plain and galvanized nails rust out long before the slate, per NPS Preservation Brief 29; natural slate lasts 60 to 150 years, per the InterNACHI life-expectancy chart, with premium slate commonly 100-plus years, per the National Slate Association.
- Historic clay tile roof restoration — Historic clay tile roof restoration matches replacement tile by profile, color, glaze, and texture and fastens with copper, because clay tile carries one of the longest life expectancies among historic roofing materials at about 100 years and most failures stem from fasteners, flashing, or sheathing rather than the tile, per NPS Preservation Brief 30.
- Historic wood and cedar shingle restoration — Historic wood and cedar shingle restoration matches the original handsplit or sawn shingle in size, shape, texture, and exposure and fastens red cedar with hot-dipped zinc-coated, aluminum, or stainless steel nails, never copper, because a chemical reaction between cedar and copper shortens the roof life, per NPS Preservation Brief 19; a wood shingle roof lasts about 25 years, per the InterNACHI life-expectancy chart.
- Historic metal and copper roof restoration — Historic metal and copper roof restoration repairs standing-seam and flat-seam terne and copper roofs, because a properly designed and installed copper roof carries a service life in excess of 100 years, per the Copper Development Association, and a copper roof lasts 70-plus years, per the InterNACHI life-expectancy chart.
How Do You Know If You Need Historic Roof Restoration?
- A slate roof with 20% or more of the slates broken, cracked, missing, or sliding out of position crosses the threshold where full slate replacement costs less than individual repairs, per NPS Preservation Brief 29, while a slate roof below 20% damage favors selective in-kind repair.
- Slates sliding or hanging loose with rust staining at the nail line indicates plain or galvanized steel fasteners corroding before the slate, the most common slate-roof failure mode, because non-ferrous copper or stainless steel nails outlast plain steel, per NPS Preservation Brief 29.
- Clay tiles slipping out of course with corroded iron fasteners indicates a fastener, flashing, or sheathing failure rather than tile failure, because clay tile outlasts its fasteners at about 100 years, per NPS Preservation Brief 30.
- Wood shingles cupped, split, or replaced with an asphalt patch on a building that originally carried slate or tile departs from the historic material, because Standard 6 directs that deteriorated historic features be repaired rather than replaced and any replacement match the old in material, per the Secretary of the Interior's Standards.
- A copper or terne metal roof with open flat-lock seams, lifted standing seams, or bare un-patinated terne signals seam and coating deterioration, because terne required periodic painting to last and a properly installed copper roof reaches a service life in excess of 100 years, per NPS Preservation Brief 4 and the Copper Development Association.
- A notice from the municipal Historic Preservation Commission regarding exterior roof work indicates the property sits in a designated local historic district or is a designated landmark, where a Certificate of Appropriateness is typically required before roofing work begins, per N.J.S.A. 40:55D-107 and the municipal Historic Preservation Commission.
- Water intrusion staining ornamental plaster, decorative woodwork, or historic finishes below a failing roof indicates active roof failure threatening character-defining interior fabric, the condition that prioritizes restoration to retain the historic character, per the Secretary of the Interior's Standards, Standard 2.

How Do Our Roofing Contractors Perform Historic Roof Restoration?
Newark Quality Roofing documents the historic roof and repairs deteriorated original material in kind before considering replacement, because the Secretary of the Interior's Standards, Standard 6, directs that deteriorated historic features be repaired rather than replaced. A Newark Quality Roofing restoration photographs, measures, and records the existing roof — the patterning, coursing, color variation, and material dimensions — and retains physical samples from unweathered areas, per NPS Preservation Brief 4. Where the severity of deterioration requires replacement, the new feature matches the old in design, color, texture, and, where possible, material, per the Secretary of the Interior's Standards, Standard 6, and salvageable slates and tiles are sounded and reused rather than discarded.
Newark Quality Roofing matches fasteners, flashing, and repair method to each historic material, because the fastener metal differs by material and a compatible fastener outlasts an incompatible one, per NPS Preservation Briefs 19, 29, and 30. Historic slate and clay tile take non-ferrous fasteners — solid copper or stainless steel — and historic slate is repaired with a ripper and a copper strip or slate hook and is never coated, sealed, or painted, per NPS Preservation Brief 29. Red cedar takes hot-dipped zinc-coated, aluminum, or stainless steel nails, never copper, because a chemical reaction between cedar and copper shortens the roof life, per NPS Preservation Brief 19. Flashing on a historic slate roof uses a durable metal with a life comparable to the slate — copper, lead-coated copper, or terne-coated stainless steel — per NPS Preservation Brief 29, and a Newark Quality Roofing crew does not walk directly on slate or high-profile clay tile, per NPS Preservation Briefs 29 and 30.
Newark Quality Roofing coordinates the restoration with the local historic-district approval, because a Certificate of Appropriateness is typically required before exterior roof work on a designated landmark or a contributing property in a local historic district, per N.J.S.A. 40:55D-107. A Certificate of Appropriateness is issued by the municipal Historic Preservation Commission. Listing in the National or New Jersey Register alone places no restriction on a private owner using private funds, per the National Park Service and the NJ DEP Historic Preservation Office, so the binding gate for a private reroof is the local ordinance and the Certificate of Appropriateness, not the Register listing. A Certificate of Appropriateness from the Historic Preservation Commission is a separate approval from a construction permit under the NJ Uniform Construction Code, and a reroof in a local district commonly requires both, per N.J.S.A. 40:55D-107 and the NJ Uniform Construction Code.
What Residential Historic Roof Restoration Do We Provide?
Newark Quality Roofing restores historic residential roofs across Essex County — the Victorians, colonials, and slate, tile, and cedar homes of Newark, Montclair, and Glen Ridge — matching the original material in kind beneath an upgraded underlayment. Newark Quality Roofing upgrades the flashing and underlayment beneath the restored historic surface for water protection. A repair or in-kind re-roof of the roof covering on a detached one- and two-family dwelling counts as ordinary maintenance under N.J.A.C. 5:23-2.7 and requires no construction permit, per the NJ Uniform Construction Code, while a designated landmark or a contributing property in a local historic district still requires a Certificate of Appropriateness from the municipal Historic Preservation Commission, per N.J.S.A. 40:55D-107.
A Newark Quality Roofing residential restoration matches natural slate, clay tile, wood shingle, or historic metal in profile, color, and texture and fastens each material to its own specification — copper or stainless steel for slate and tile, zinc-coated or stainless steel for red cedar — per NPS Preservation Briefs 19, 29, and 30. Glen Ridge established its Historic Preservation Commission by ordinance in 1987, and the Glen Ridge Historic District covers over 90% of the Borough under a local ordinance, per the Borough of Glen Ridge Historic Preservation Commission, so a Newark Quality Roofing restoration in such a district coordinates the Certificate of Appropriateness before work begins. A homeowner pursuing tax incentives is routed to a tax professional, the National Park Service, and the NJEDA, because the federal 20% Historic Rehabilitation Tax Credit applies to income-producing certified historic structures only, and owner-occupied residences do not qualify, per the NPS and the IRS.
What Commercial Historic Roof Restoration Do We Provide?
Newark Quality Roofing restores historic commercial and institutional roofs across Essex County — churches, civic and landmark buildings, and contributing commercial structures — repairing slate, clay tile, and copper in kind under the Secretary of the Interior's Standards. A copper roof on a historic civic or religious building carries a service life in excess of 100 years when properly designed and installed, per the Copper Development Association, and standing-seam, batten-seam, and flat-seam copper are the standard historic sheet-copper systems.
A Newark Quality Roofing commercial historic restoration coordinates with the municipal Historic Preservation Commission, the owner's architect, and the NJ DEP Historic Preservation Office, because a Certificate of Appropriateness is typically required before exterior roof work on a designated landmark or a contributing property in a local historic district, per N.J.S.A. 40:55D-107. The federal 20% Historic Rehabilitation Tax Credit, IRC §47, applies to certified rehabilitation of income-producing certified historic structures and remains in effect in 2026, per the IRS and the NPS, and the NJ Historic Property Reinvestment Program administered by the NJEDA applies to income-producing historic properties; a tax professional, the NPS, and the NJEDA determine eligibility, and Newark Quality Roofing does not assess credit eligibility.
What Are the Steps in Our Historic Roof Restoration Process?
- Documentation and Condition Assessment
A Newark Quality Roofing crew photographs, measures, and records the existing historic roof — the patterning, coursing, color variation, and material dimensions — and identifies salvageable original material, per NPS Preservation Brief 4 and general preservation practice across NPS Preservation Briefs 4, 19, 29, and 30.
- Historic Preservation Commission Coordination
A Newark Quality Roofing crew confirms whether the property is a designated landmark or sits in a local historic district and coordinates the Certificate of Appropriateness with the municipal Historic Preservation Commission, because a Certificate of Appropriateness is typically required before exterior roof work, per N.J.S.A. 40:55D-107, separate from a construction permit under the NJ Uniform Construction Code.
- In-Kind Sample Matching
A Newark Quality Roofing crew sources and approves matching in-kind samples — slate matched in color and texture, clay tile matched in profile and glaze, wood shingle matched in size and exposure, metal matched in profile — before full installation, because Standard 6 directs that any replacement match the old in design, color, texture, and, where possible, material, per the Secretary of the Interior's Standards.
- Repair of Original Material
A Newark Quality Roofing crew repairs deteriorated original roofing rather than replacing it where possible, replacing individual slates with a ripper and a copper strip or slate hook and reusing sounded, salvageable slates and tiles, per NPS Preservation Brief 29 and the Secretary of the Interior's Standards, Standard 6.
- Material-Specific Fastening and Flashing
A Newark Quality Roofing crew fastens each material to its own specification — copper or stainless steel for slate and clay tile, zinc-coated, aluminum, or stainless steel for red cedar — and installs flashing in a metal with a life comparable to the roof, per NPS Preservation Briefs 19, 29, and 30.
- Underlayment Upgrade and Verification
A Newark Quality Roofing crew upgrades the underlayment and flashing beneath the restored historic surface for water protection, verifies the restoration against the matching in-kind samples, and records the completed work, per NPS Preservation Brief 4 and general preservation practice.
