Vermont Historic Home Types & Their Roofs
Vermont's housing stock reflects over 200 years of New England building tradition. Each architectural style has distinctive roofing characteristics that inform material selection and preservation approach. Understanding your home's style helps you make roofing decisions that honor its heritage while meeting modern performance requirements.
Vermont Farmhouse (1780–1900)
The quintessential Vermont building. Characterized by connected farm buildings (“big house, little house, back house, barn”), gable roofs at moderate pitch (8:12 to 10:12), and often multiple roof sections at different heights. Original roofing was typically wood shingles, later replaced with standing seam metal in the mid-1800s.
Appropriate materials: Standing seam metal (painted steel or terne), Vermont slate, architectural shingles that approximate metal or slate profiles
Federal/Colonial (1780–1830)
Symmetrical facades, hip or gable roofs, and restrained ornamentation. Vermont colonials feature moderate to steep pitches (8:12 to 12:12) and are found in village centers throughout the state. Original roofing was wood shingles or early Vermont slate.
Appropriate materials: Vermont slate (preferred), standing seam metal, high-quality architectural shingles with slate-like profile
Greek Revival (1830–1860)
Vermont's most common historic style. Features low-pitched gable roofs (4:12 to 6:12), wide cornices with returns, and temple-front designs. The lower pitch creates challenges for water management and ice dam formation. Originally roofed with tin or early standing seam metal.
Appropriate materials: Standing seam metal (historically accurate), low-profile slate, membrane systems hidden behind cornices
Victorian/Queen Anne (1870–1910)
Complex roof forms with steep pitches, multiple gables, turrets, and decorative elements. Vermont Victorians often feature patterned slate in multiple colors as a design element. The complex geometry creates many valleys, intersections, and flashing challenges.
Appropriate materials: Patterned Vermont slate (highest preservation value), solid-color slate, standing seam metal accents
Vermont Division for Historic Preservation
The Vermont Division for Historic Preservation (VDHP) is the state agency responsible for identifying, evaluating, and protecting Vermont's historic resources. If your home is listed on the National Register or within a designated local historic district, the VDHP plays a role in your roofing project.
When VDHP Review Is Required
- Seeking state or federal historic tax credits: All work must be reviewed and approved by VDHP before construction begins to qualify for credits
- Using state or federal grant funding: Projects funded by Vermont Community Development grants, USDA rural development, or other public sources require VDHP review under Section 106
- Local historic district review: Some municipalities (Burlington, Woodstock, Bennington, Stowe) have local historic districts with design review boards
Even when formal review is not required, VDHP provides free technical assistance to homeowners of historic properties. Their staff can advise on appropriate materials and connect you with experienced preservation contractors.
Secretary of the Interior's Standards for Rehabilitation
All historic tax credit projects must comply with these Standards. For roofing, the key standards are:
- Standard 2: The historic character of a property shall be retained and preserved. Replacement roofing materials should match the original in material, design, color, and texture.
- Standard 5: Distinctive features and construction techniques shall be preserved. Original slate patterns, metal profiles, and decorative elements should be replicated.
- Standard 6: Deteriorated historic features shall be repaired rather than replaced. Where replacement is necessary, the new feature shall match the old in design, color, texture, and materials.
- Standard 9: New additions or alterations shall not destroy historic materials. Modern components (ice barrier, synthetic underlayment, ridge vents) must not alter the historic appearance.

Approved Roofing Materials for Historic Homes
Material selection is the most critical decision when roofing a Vermont historic home. The right choice honors the building's heritage, meets modern code requirements, and withstands Vermont's demanding climate.
Vermont Slate
Vermont has produced some of the world's finest roofing slate since the 1840s. Quarries in the Slate Valley (Fair Haven, Poultney, Castleton) and the Green Mountain region produce unfading green, unfading gray, unfading purple, and variegated colors. Vermont slate lasts 100 to 200 years when properly installed, making it the most historically appropriate and longest-lasting option for formal Vermont homes.
Standing Seam Metal
Standing seam metal has been used on Vermont buildings since the early 1800s, particularly on farmhouses, agricultural buildings, and Greek Revivals. Vertical seams and smooth surfaces shed snow effectively. Historic profiles feature 1-inch to 1.5-inch seams at 16 to 20 inch panel widths. Modern standing seam in painted Galvalume, copper, or zinc provides authentic appearance with improved longevity.
Architectural Shingles
While not historically authentic, high-quality architectural shingles are sometimes permitted on contributing structures in historic districts when cost makes slate or metal prohibitive. The best options for historic applications feature thick, heavyweight profiles that approximate the shadow lines of slate. Colors like Weathered Wood, Slate Gray, and Colonial Slate complement historic architecture.
State & Federal Historic Tax Credits
Vermont offers generous tax incentives for historic building rehabilitation that can significantly offset the cost of a historically appropriate roof replacement.
Vermont State Credit (10%)
Available for qualified rehabilitation expenses on National Register properties. Applies to the owner's Vermont income tax liability. Both residential and commercial properties qualify. Minimum expenditure must exceed $5,000. Work must comply with Secretary of the Interior Standards and be reviewed by VDHP.
Example: $30,000 slate roof = $3,000 state tax credit
Federal Credit (20%)
Available for certified rehabilitations of certified historic structures used for income-producing purposes (rental properties, businesses, mixed-use). The 20% credit applies to qualified rehabilitation expenditures and must be taken over five years. Work must be certified by the National Park Service through VDHP.
Example: $30,000 slate roof on rental = $6,000 federal tax credit
Snow Load & Structural Considerations
Many Vermont historic homes were built before modern structural engineering. When replacing the roof, evaluate whether the existing structure handles current code requirements and the weight of new roofing material.
Critical Structural Factors
- Material weight: Vermont slate weighs 7 to 10 lbs/sqft, far more than shingles (2-3 lbs/sqft) or metal (1-2 lbs/sqft). Converting to slate requires structural verification.
- Rafter sizing: Pre-1900 homes often used hand-hewn rafters that may be undersized by modern standards. Common historic rafter sizes (2x6 at 24-inch spacing) may not meet current snow load requirements above 60 psf.
- Ice dam history: Chronic ice dams may have caused hidden structural damage including rotted rafter tails and weakened connections. Thorough inspection during tear-off is essential.
- Modern code requirements: New roofing must meet current code for ice barrier, ventilation, and structural load, even on historic structures. The challenge is meeting these requirements without visibly altering historic character.
Repair vs. Full Replacement
From a preservation standpoint, repairing an existing historic roof is always preferable. The Secretary of the Interior's Standards explicitly prioritize repair over replacement. However, there are situations where full replacement is the better choice.
Repair Is Best When:
- Less than 20% of slates or metal panels need replacement
- Flashing failures are localized and repairable
- The underlayment is still serviceable
- Structural framing is sound
- The roof is within its expected lifespan
Full Replacement Is Best When:
- More than 30-40% of slates or panels have failed
- Widespread underlayment failure allows water penetration
- Structural damage requires deck or rafter work
- Multiple patch repairs have compromised integrity
- Insurance or code requirements mandate full replacement
Choosing a Contractor for Historic Work
Historic roofing requires specialized skills beyond standard residential roofing. Choosing the wrong contractor can damage irreplaceable historic materials, forfeit tax credit eligibility, and require costly corrections.
What to Look For
- Documented experience with Vermont historic homes (portfolio of completed projects)
- Knowledge of VDHP review process and Secretary of the Interior Standards
- Specific experience with the material you need (slate installation is specialized)
- References from VDHP, local historical societies, or preservation organizations
- Understanding of Vermont snow load and ice dam requirements
- Willingness to work with VDHP staff during project review

Do I need approval to replace the roof on a Vermont historic home?
If your property is listed on the National Register or is within a local historic district, you may need approval from the Vermont Division for Historic Preservation or your local review board. Even if not legally required, seeking guidance ensures you maintain eligibility for historic tax credits and preserve your home's character.
What roofing materials are approved for Vermont historic homes?
Approved materials depend on the building's historic character. Slate is preferred for formal homes. Standing seam metal (terne, copper, painted steel) suits farmhouses and agricultural buildings. Wood shingles may be acceptable for certain periods. Architectural shingles may be permitted if they replicate the original appearance.
Are there tax credits for restoring a Vermont historic home roof?
Vermont offers a 10 percent state historic tax credit for qualified rehabilitation expenses on National Register properties. The federal government offers a 20 percent credit for certified rehabilitations of income-producing certified historic structures. Roof replacement typically qualifies when done per Secretary of the Interior Standards.
How much does it cost to replace a slate roof on a Vermont farmhouse?
A full Vermont slate roof replacement typically costs $15 to $30 per square foot installed, or $22,500 to $45,000 for a 1,500 square foot roof. Costs vary by slate quality, roof complexity, accessibility, and structural needs. Salvaging existing slates can reduce costs.
Can I use architectural shingles on a Vermont historic home?
It depends on your property's historic status. National Register properties seeking tax credits generally need materials matching the original. Some local districts allow high-quality architectural shingles that approximate slate shadow lines. Properties without historic designation can use any code-compliant material.
What is the Vermont Division for Historic Preservation?
The VDHP is part of the Agency of Commerce and Community Development. It administers the National Register program, reviews historic tax credit projects, provides preservation technical assistance, and maintains the Vermont Historic Sites Survey. Contact: (802) 828-3211 or accd.vermont.gov/historic-preservation.
How do Vermont snow loads affect historic home roofing?
Vermont ground snow loads range from 50 to 80 psf. Many historic homes predate modern snow load codes and may have undersized rafters. A structural assessment is critical when replacing the roof. Sister rafters or collar ties may be needed, and modern ice barrier is required by code even on historic structures.
Should I repair or replace my Vermont historic home slate roof?
If less than 20 percent of slates are damaged, selective repair is usually best financially and for preservation. If more than 30 to 40 percent have failed, full replacement is likely more cost-effective. The condition of the underlayment and deck is often the deciding factor.
