Historic Roof Restoration in Mandeville, the Northshore & Baton Rouge
Slate, copper, ceramic tile, wood shake, terne metal — HDC-compliant restoration to NPS Preservation Brief 4 standards, photograph-documented for Federal 20% and Louisiana 25% Historic Tax Credit applications. Serving the greater South Louisiana area from our Mandeville HQ.
A historic roof restoration is not a roof replacement with old materials — it is a different category of work. The local historic district commission has approval authority over the material, the installation method, and sometimes the color and flashing spec. The Federal and Louisiana Historic Tax Credit programs require the work to meet the Secretary of the Interior's Standards for the Treatment of Historic Properties and the National Park Service's Preservation Brief 4 on roofing for historic buildings. Original material gets salvaged and reinstalled where possible, not thrown in the dumpster. Period-appropriate flashing — copper, lead, or lead-coated copper — replaces galvanized that has reached the end of life. And every step is photograph-documented because the homeowner's tax-credit application depends on it.

The Historic Preservation Framework
Three regulatory layers govern a historic roof restoration in South Louisiana. The work must satisfy each layer it falls under, and the homeowner's tax-credit eligibility depends on it.
Layer 1 — The local historic district commission
In Orleans Parish, the Historic District Landmarks Commission (HDLC) holds permit-approval authority over Vieux Carré, Garden District, Esplanade Ridge, Bywater, Faubourg Marigny, Holy Cross, Treme, Lower Garden District, Algiers Point, Central Business District, Warehouse District, and Lafayette Square historic districts. On the Northshore, the Old Mandeville Historic District and Old Covington Historic District operate under municipal preservation commissions with their own scope. Each district has slightly different rules regarding which materials are permitted, which installation methods are acceptable, and whether synthetic substitutes are approved on a property-by-property basis.
Layer 2 — The Secretary of the Interior's Standards
Ten standards govern the treatment of historic properties for federal and state tax-credit eligibility. The roofing-relevant standards are summarized in National Park Service Preservation Brief 4 — Roofing for Historic Buildings, which addresses material selection, flashing material, installation method, salvage discipline, and the documentation expected for credit applications. Work that satisfies the local HDC may still fail the Secretary's Standards due to a detail that disqualifies it from tax credits. Epic Roofing builds to the Standards regardless of whether the homeowner intends to claim credits.
Layer 3 — The tax-credit programs
The Federal Historic Tax Credit is 20 percent of qualified rehabilitation expenses on income-producing historic properties (rental, commercial, mixed-use). The Louisiana State Commercial Historic Tax Credit is 25 percent for qualifying commercial work in cultural districts. The Louisiana Owner-Occupied Historic Tax Credit program provides 25 percent for owner-occupied historic homes in qualifying districts. Each program has its own application package, deadlines, and documentation standards — Epic Roofing produces the work package; the homeowner or their tax-credit consultant files the application.
Historic Roof Materials We Restore
Epic Roofing restores the materials historically installed on South Louisiana residential and small-commercial buildings. The discipline differs by material, but the salvage-first, period-appropriate-flashing, photograph-documented framework runs consistently across all of them.
- Natural slate — Vermont, Pennsylvania, Spanish, and Welsh slate. On a historic contributing property, we layer the preservation framework discipline on top. See slate roofing.
- Ceramic and clay tile — Spanish, Mission, and French Quarter pan tile are common on NOLA historic stock. Salvage-and-reinstall capability where the original tile is largely sound; matched-source replacement tile for failed pieces.
- Copper, copper terne, and lead-coated copper — used historically for low-slope cottage roofs, valleys, dormer cheeks, and accent details. Restoration includes soldering and lock-seam reconstruction rather than mechanical replacement where the original material is recoverable.
- Standing-seam tin and historic metal — common on NOLA Creole cottages and shotgun houses. We coordinate historic-metal restoration with the standing seam metal page's product depth for a new contemporary metal scope.
- Wood shake and wood shingle — cedar and historic cypress shake on select contributing properties. Restoration scope coordinated case-by-case; some projects route through a wood-shake specialist partner where the original material grade requires it.
- Historic asphalt — early-period asphalt shingles on contributing properties that post-date the district's period of significance but predate modern shingle warranties. Restoration scope only where the local HDC permits.
Salvage-and-Reinstall: The Discipline Test
In a historic restoration, the original material on the roof is part of what makes the property historic. Throwing it in the dumpster and installing a new roof replaces a historic roof, which fails the Secretary's Standards on Standard 6 (deteriorated historic features shall be repaired rather than replaced), disqualifies tax credits, and may trigger HDC enforcement action, depending on the district. Epic's salvage discipline runs in four steps:
Assessment
We grade the existing material piece by piece — sound, salvageable with conservation, or beyond salvage. On a 100-year-old Vermont slate roof, 60 to 80 percent of the pieces are typically still sound; only 5 to 15 percent are beyond salvage.
Careful removal
Sound and salvageable pieces come off the roof intact, by hand, course by course. Course positions are photo-documented before removal, so reinstalling returns each piece to close to its original location.
Conservation
Salvageable pieces get treatment before reinstall — minor crack stabilization and hole patching for slate, soldering and seam reconstruction for copper, cleaning and stabilization for clay tile.
Matched-source replacement
The 5 to 15 percent beyond salvage gets replaced with matched-source material: same quarry for slate, where possible, era-matched architectural-salvage tile for ceramic, matched alloy for copper. Most restorations end at 80 to 95 percent original material, restored, with matched replacement filling the gaps.
Period-Appropriate Flashing + Photo Documentation
Two details routinely disqualify otherwise good historic restoration work from tax-credit eligibility: wrong flashing material and missing documentation.
Flashing
- On a 100-year-life slate, tile, or copper roof, the flashing must outlive the primary material. Galvanized steel fails in 25 to 40 years. Copper, lead, and lead-coated copper run 75 to 150 years and match the historic specification.
- Period-appropriate flashing is what the Secretary's Standards require on a contributing property and what tax-credit reviewers verify on the application.
- Epic Roofing specifies copper or lead on every historic restoration — the alternative is losing tax-credit eligibility on a 25 percent or 20 percent line item that dwarfs the flashing upcharge.
Documentation
- The tax-credit application requires before-work photographs, in-progress photographs at each work phase, after-work photographs, and a written narrative of the work performed, mapped to the Secretary's Standards.
- Epic Roofing produces the full photograph package as part of every historic restoration project — over 100 photographs on a typical residential restoration, indexed and captioned to the work phases.
- The homeowner hands this package to their accountant or historic-preservation tax-credit consultant; we do not file the application itself.
When a Synthetic Substitute Is (or Isn't) Acceptable
DaVinci composite slate and similar synthetic substitutes occasionally come up in restoration conversations. Whether a synthetic is acceptable depends on three factors: the local HDC's published policy, the property's status (contributing vs. non-contributing), and the homeowner's tax credit goals.
- Contributing property in a designated district with tax-credit pursuit: natural material is almost always required. Synthetics generally disqualify tax credits and may fail HDC review.
- Non-contributing property inside a district overlay: HDCs frequently approve synthetics with documentation showing the property is non-contributing. Tax-credit eligibility usually does not apply to non-contributing properties, so the synthetic decision is purely a cost vs. aesthetic one.
- Property outside any historic district overlay but in a historic-style neighborhood: synthetics are widely used, and the composite slate roofing page covers DaVinci scope. The preservation framework does not apply because there is no regulatory overlay.
- Secondary structures (garage, carriage house, dependency) on contributing-property lots: HDC treatment varies; some approve synthetics on secondary structures even when requiring natural on the primary structure.
We do the synthetic-vs-natural walkthrough at the on-site consultation, with the specific district overlay and contributing-status check pulled from the HDC's published records.
Old Mandeville Historic District — Vermont slate restoration on 1898 contributing property We bought a contributing home in Old Mandeville with original Vermont slate that had been patched poorly by the prior owner. Three roofers told us the only option was tear-off and full reroof — at six figures. Epic walked the roof, graded every slate piece by hand, and showed us 78 percent of the original Vermont slate was still sound. Joey's crew removed it course by course, conserved the salvageable pieces, sourced matched Vermont slate from an active quarry for the 22 percent that was beyond salvage, and reinstalled with new copper flashing and a sealed deck per Preservation Brief 4. The photo-documentation package he handed us went straight to our historic-preservation tax-credit consultant; we cleared the State 25 percent credit on the qualifying expenses. The roof looks like it has been there since 1898 — because most of it has. — Verified Google review, Old Mandeville Historic District
Historic Roof Restoration FAQs
Does Epic Roofing file the tax-credit application for me?
No. Epic Roofing produces the work package and the photo-documentation package that the application requires. The application is filed by the homeowner, the homeowner's accountant, or a historic-preservation tax-credit consultant. We can recommend qualified consultants who routinely file Louisiana and Federal credit applications and know the current state program scope and deadlines.
How much more does a historic restoration cost than a standard reroof?
Typically, 30 to 80 percent more than a standard reroof of comparable size. The cost is driven by salvage discipline (hand removal and conservation rather than tear-off), period-appropriate flashing material (copper or lead vs galvanized), matched-source replacement material, and the photo-documentation labor. The State 25 percent tax credit on qualifying expenses typically offsets most of the differential for owner-occupied homes in qualifying districts.
Can the HDC actually reject my roof permit?
Yes, and it happens regularly when homeowners or unfamiliar contractors submit non-conforming material or an installation method. The NOLA HDLC and the Old Mandeville HDC publish review schedules and material standards. We pull the current district standards before specifying materials and, where possible, pre-vet the spec with the permit office to avoid surprises at the review meeting.
What if my home is in a historic district but is a non-contributing property?
Non-contributing properties within an HDC overlay are subject to district review, but with relaxed standards for materials and methods. Tax credits typically do not apply (credits are tied to contributing status). The composite slate roofing page covers DaVinci synthetic as a non-contributing-property option that delivers a slate aesthetic without the contributing-property material restrictions.
Do you do wood shake restoration?
Some wood-shake restoration scopes we handle directly; some projects route through a wood-shake specialist contractor who works to the same Preservation Brief 4 standards we use. The on-site consultation determines which path fits — driven by the original material grade, the salvage condition, and the district's published material standards.
How long does a historic restoration take vs a standard reroof?
Standard reroof on a 2,000 to 3,000 sq ft home runs 2 to 4 days. Historic restoration of comparable size typically runs 2 to 4 weeks. The hand removal, conservation, and matched-source replacement workflow takes time. Plan the schedule accordingly — historic restoration is not a fast project, and forcing a fast schedule degrades the salvage discipline that the tax credit and HDC review depend on.
Will the restored roof last as long as the original?
Often longer. The original Vermont slate, Spanish tile, or copper specification is typically a 75 to 150-year material. The conservation discipline, new copper flashing, and modern underlayment under the salvaged material usually extend the roof another 75 to 100 years from the restoration date. The roof on a 1898 home restored in 2026 is realistically a roof for the home's next century.
Schedule a Restoration Consultation
Historic restoration starts with the on-site consultation — we walk the roof, grade the existing material, pull the district overlay and contributing-status records, and lay out the salvage scope, flashing spec, documentation plan, and tax-credit pathway in writing. No tear-off commitment, no permit submission, no contract signed at the consultation visit.
