Georgetown Historic Home Roofing Guide

Roofing in Georgetown — Why It Is Different

Georgetown is one of Washington DC's oldest neighborhoods, with homes dating from the late 1700s to the mid-1900s. The Georgetown Historic District is protected by the DC Historic Preservation Review Board (HPRB) and the Old Georgetown Board (OGB), which is part of the US Commission of Fine Arts. These oversight bodies require that exterior changes — including roofing — maintain the neighborhood's historic character. This means Georgetown homeowners face additional requirements, longer timelines, and potentially higher costs compared to roofing projects in non-historic areas. However, these regulations also protect property values by maintaining the architectural integrity that makes Georgetown one of the most desirable neighborhoods in the country. Average property values exceed $1.5 million, making proper roof maintenance a critical investment.

Old Georgetown Board Requirements for Roofing

Any exterior alteration visible from a public way in Georgetown must be reviewed by the Old Georgetown Board. For roofing, this means material changes, color changes, and additions of visible features (skylights, dormers, satellite dishes, solar panels) require OGB review and approval. Replacement in kind — using the same material and color as the existing roof — is typically approved through a streamlined review process. If you want to change from one material to another (for example, replacing old slate with architectural shingles), you will need to present your case at a public hearing. The OGB meets twice monthly, and applications should be submitted at least three weeks before the desired hearing date. Your contractor should prepare the application package, which includes photographs, material samples, and a written description of the proposed work.

Approved Roofing Materials for Georgetown Homes

The most commonly approved roofing materials for Georgetown's historic homes include natural slate (the original and most historically appropriate material for many Georgetown homes), standing seam metal (traditional terne-coated or copper for visible roof areas), and architectural asphalt shingles (generally approved for non-visible roof areas or where the existing material is shingle). Synthetic slate products have gained some acceptance for properties where natural slate is cost-prohibitive, but approval varies case by case. Cedar shake may be approved for specific properties where it was the original material. TPO, EPDM, and other membrane systems are acceptable for flat roof sections that are not visible from public view. Color is important too — the OGB generally requires muted, historically appropriate colors. Bright or non-traditional colors will likely be denied.

Cost Considerations for Georgetown Roofing

Roofing a Georgetown historic home typically costs 20 to 50% more than a comparable project in a non-historic area. Natural slate installation runs $20 to $35 per square foot, compared to $5 to $9 for standard architectural shingles. Slate repair — replacing individual broken slates — costs $300 to $800 per repair depending on accessibility and material matching. Standing seam copper roofing, appropriate for many Georgetown homes, costs $25 to $40 per square foot. Beyond material costs, the additional expenses include OGB application and review fees, potential design professional fees for complex applications, the premium for contractors experienced in historic preservation, and longer project timelines due to the review process. Despite the higher costs, these investments protect both the home's historic integrity and its substantial market value.

Finding a Contractor for Georgetown Historic Homes

Not every roofing contractor is qualified to work on Georgetown's historic properties. The ideal contractor has specific experience with the OGB review process, demonstrated expertise in working with historic materials (particularly slate), familiarity with preservation standards, and the patience to navigate the approval process. They should be able to show you previous Georgetown projects with photos and references. Avoid contractors who seem unfamiliar with the OGB process or who dismiss the historic requirements as unnecessary bureaucracy — these regulations are the law, and violations can result in stop-work orders, fines, and required removal of non-compliant materials. Look for contractors who embrace the historic preservation aspect and take pride in maintaining Georgetown's character.
