Replacing a Roof in the Annapolis Historic District: Permits & HPC Approval

Replacing a roof inside the Annapolis Historic District involves two separate approvals from two different bodies, and homeowners routinely discover the second one after they’ve signed a contract. Written by roofers in Annapolis, MD, this guide sets out who issues what, when the fast administrative route is available, and what the Historic Preservation Commission actually reviews. Including the cases where it has said no.

Every regulatory statement below was checked against the City of Annapolis and Anne Arundel County’s own published material in August 2026. Rules change, and this is a page whose only value is being correct, so verify anything decision-critical with the Historic Preservation Division before you commit money. Their standing advice is worth repeating: ask first, apply early: before signing a contract or starting work.

Do I need a permit to replace my roof in Annapolis?

Yes. The City Code’s requirement is broad: any owner intending to construct, enlarge, alter, repair, move, or demolish a building must apply for the permits the Code requires. A re-roof is an alteration and repair of the structure, so it falls inside that.

There is a narrow permit exemption in the Code, and it’s worth knowing precisely because it does not help you here: the exemption covers non-structural replacement or repair of windows, doors and siding, on residential projects outside the Historic District. Roofing is not on that list, and neither is anything inside the district.

City or county, who issues it?

This is the single most common point of confusion, and getting it wrong costs a week minimum.

The City of Annapolis is separately incorporated and runs its own permitting. The City’s Department of Planning and Zoning is a full-service municipal agency handling development review, permitting, inspections and licensing under the City Code, including construction and Critical Area compliance. If your property is inside city limits, you apply to the City. Anne Arundel County does not process it.

Outside city limits, the county handles it. Anne Arundel County’s Inspections and Permits department issues permits for unincorporated areas (Edgewater, Crofton, Davidsonville, Arnold, Severna Park and the rest) through its Land Use Navigator portal.

The trap is postal addresses. Plenty of properties carry an Annapolis mailing address while sitting outside the municipal boundary, in county jurisdiction. Your mailing address does not determine which authority reviews your permit; the city limit does. If you’re not certain which side of the line you’re on, establish that before anything else, because it changes the application, the fee schedule and the inspection process.

City applications go through the Citizen Self Service portal. The Department of Planning and Zoning can be reached at (410) 263-7961 or permitting@annapolis.gov.

The second approval: a Certificate of Approval

Inside the Historic District, the building permit is only half of it. Exterior work requires a Certificate of Approval from the Historic Preservation Commission, under Chapter 21.56 of the City Code.

The scope is wider than most people expect. Per the Code, all exterior projects in the Historic District require a Certificate of Approval whether or not the work is exempt from a building permit. So the fact that a job is minor, or wouldn’t need a permit elsewhere in the city, doesn’t remove the HPC step.

The Historic Preservation Division sits within Planning and Zoning at 145 Gorman Street, 3rd Floor, and can be reached at (410) 260-2200 or HistPres@annapolis.gov.

What if the work isn’t visible from the street?

This is asked constantly, usually hopefully, and the honest answer is more nuanced than either version you’ll hear from contractors.

Visibility does not exempt you from needing approval. We could not find any provision in the City’s material exempting roof work that isn’t visible from the public way, and the Code’s language covers all exterior projects in the district. Anyone telling you a rear slope needs no approval at all is guessing.

What visibility does change is the intensity of review and the flexibility on materials. The Commission and its staff focus on what is visible from the public way. In practice that means a street-facing slope gets scrutinised on material, profile and finish in a way a concealed rear slope may not, and a material that would not be accepted on a visible elevation can be acceptable behind a parapet or on a hidden plane.

The recent terne-coated metal case below shows exactly this split in action: replacement of the visible historic roof was refused, while a TPO treatment on the back roof was deemed approvable in the same review.

When approval is administrative rather than a hearing

Not every job goes to a public hearing. Straightforward work can be handled by staff, and this is the difference between weeks and months.

Staff may issue an administrative Certificate of Approval for work that meets the published guidelines, typically genuine like-for-like replacement matching the existing materials and appearance. Where it applies, the certificate is issued immediately following staff review.

Two qualifications matter:

• “Replacement in kind” has a specific meaning.

  It applies where materials are extensively deteriorated or damaged and cannot be repaired, and the deteriorated material is replaced with the same material. Swapping slate for asphalt is not replacement in kind, however similar the colour.

• Staff can refer it up.

  If there’s uncertainty about whether an application meets the criteria, staff may refer it to the full Commission, so the administrative route is available, not guaranteed.

What the administrative application needs

Per the City’s administrative application guidelines, submissions include a description of the work, drawings or acceptable substitutes, specifications, and photographs, plus a letter of concurrence from an easement holder where one exists.

A site plan is not required for the replacement or repair of roofs, siding, windows and doors, or miscellaneous repairs. That’s a genuine simplification and it’s written into the guidelines.

Photographs are not optional, and they’re where applications most often fall short. A usable set covers the full front elevation for context, all roof planes, close-ups of the deteriorated areas that justify replacement, and street-level views showing the building in its setting. If your argument is that the existing material has failed, the photographs have to show it.

In practice a complete package also carries product data (the profile, thickness, fastener type and underlayment for the proposed material) and colour confirmation by physical sample or chip for roofing, flashing, gutters and downspouts. Where a change of material would add significant weight, expect to be asked for a structural engineer’s letter.

Your building permit application separately requires contractor licensing details, including the MHIC licence number, and proof of current insurance.

What the Commission reviews against

Applications are assessed against two documents: Building in the Fourth Century: Annapolis Historic District Design Manual, the City’s own guidelines, and the Secretary of the Interior’s Standards for the Rehabilitation of Historic Properties.

The principle running through both, and the one that decides most roof cases, is that the historic character of a property should be retained and preserved, and that removal of historic material or alteration of the features that characterise a property should be avoided. Repair is preferred to replacement. Replacement is justified by demonstrated failure, not by age, inconvenience or a preference for something newer.

One useful and frequently misreported detail: the Commission does not review paint colour. The City’s design manual says so directly. You’ll find contractor pages claiming otherwise. Note the common exception worth confirming for your own property. Painting previously unpainted masonry is generally treated as a material alteration rather than a colour choice, which is a different question entirely.

Can I replace a metal roof with shingles?

Frequently not, and there’s a documented case that shows how seriously this is taken.

In a recent application, staff denied the replacement of an existing standing seam terne-coated metal roof. Following onsite inspection, and drone analysis of the roof surface, the determination was that the roof was not beyond its serviceable life and could be maintained with rust treatment and an elastomeric coating rather than replaced. A TPO treatment proposed for the rear roof was deemed approvable in the same review.

Three things are worth drawing out of that decision:

1. Serviceability is assessed, not asserted.

   “It’s old” is not a case for replacement. The Commission had the roof inspected and concluded it could be maintained.

2. Maintenance is a real alternative, and it will be proposed.

   Coating and rust treatment on historic metal is a recognised outcome, not a stalling tactic.

3. Historic materials are often irreplaceable in practice.

   Terne-coated metal cannot be accurately replicated with modern equivalents, which raises the bar for removing it substantially.

If your Historic District property has a slate, terne-coated metal, standing seam or cedar roof, plan on the starting assumption being repair. Budget for the possibility that you’ll be asked to maintain rather than replace, and get the condition properly documented if you believe genuine failure has occurred.

What materials are approved?

There is no simple approved list, because the answer depends on what’s there now, what the building is, and what’s visible.

The workable framing is:

• Matching the existing historic material is the strongest position, and the one most likely to go administrative.
• Slate, cedar and historic metals are expected to be retained and repaired where they survive and remain serviceable.
• Modern substitutes face more scrutiny the more visible the plane, and are considered more readily where they aren’t.
• Finish and profile are reviewable, not just material type. Including on gutters, downspouts and flashing, which are exterior elements like any other. Metal finishes that suit the building and match the roof or trim are generally preferred; the design manual disfavours aluminium in historic work. We’ve seen it widely asserted that bare mill-finish aluminium is flatly prohibited, and we could not confirm that wording in the manual itself, treat it as a strong steer rather than a settled rule, and ask the Division about your specific property.

Does the Critical Area affect this?

Possibly, depending where you are. Properties within 1,000 feet of tidal water or tidal wetlands fall inside the Chesapeake Bay Critical Area, and Critical Area compliance is among the City’s review responsibilities inside city limits.

For most re-roofs it changes nothing, because mitigation attaches to new lot coverage and a like-for-like replacement on the existing footprint creates none. What does implicate it is a change to the roof footprint, and, less obviously, adding gutters and downspouts where none existed.

The full picture, including how this runs outside the city line where the county rather than the City administers it, is in roofing in the Chesapeake Bay Critical Area.

How long does approval take?

The honest answer is that it depends on which route you’re on, and that nobody should quote you a fixed number.

Administrative approval, where the work qualifies and the application is complete, is issued immediately following staff review. A referral to the full Commission puts you on the hearing calendar, which is a materially longer timeline and the part of the schedule most likely to slip.

Two things reliably cost the most time, and both are avoidable: an incomplete photograph set, and material selections made before approval. Ordering non-returnable special-order material before the certificate is issued is how a project ends up choosing between a change of material and an argument about money.

The practical sequence

1. Establish jurisdiction

   city limits or county, before anything else

2. Confirm Historic District status and talk to the Historic Preservation Division early

3. Document the existing roof

   condition, material, and evidence of failure if replacement is proposed

4. Apply for the Certificate of Approval, administrative where it qualifies

5. Apply for the building permit through the City’s portal, with licence and insurance details

6. Order materials

   only now

7. Do the work, and complete inspections

Where this leaves you

The Historic District process is more forgiving than its reputation for genuine like-for-like repair work, and considerably less forgiving than people expect when they want to change materials on a visible elevation. The determining question is almost never “what would I prefer?”. It’s “can the existing material be repaired?”

For what a replacement involves once approvals are in hand, see roof replacement in Annapolis. Gutters and downspouts carry their own finish considerations in the district. See gutters. And if you’re outside the city line, roofing in Edgewater covers county permitting and the waterfront exposure issues that come with it.
