Palo Alto contains some of the Peninsula’s most architecturally significant homes—from Victorian-era Professorville residences to Craftsman bungalows in Old Palo Alto to mid-century moderns throughout the city. Roofing these properties requires more than technical skill. It demands understanding of historic preservation principles, Architectural Review Board (ARB) processes, and materials that honor the original architecture.
For homeowners in Palo Alto’s historic neighborhoods, this guide explains what you need to know before starting a roofing project.
Historic Neighborhoods and Their Requirements
Professorville
The Professorville neighborhood, roughly bounded by Kingsley, Addison, Ramona, and Cowper, contains Palo Alto’s highest concentration of historic homes. Named for the Stanford professors who built homes here in the late 1800s and early 1900s, the neighborhood features Victorian, Colonial Revival, Craftsman, and various early 20th-century styles.
ARB Status: Individual homes may have historic designation requiring ARB review for exterior changes.
Common Roofing Types:
- Wood shake (now typically replaced with fire-safe alternatives)
- Composition shingles in period-appropriate profiles
- Some original slate or tile
Key Considerations:
- Color must complement original architecture
- Profile should match period character
- Wood shake aesthetic can be achieved with Class A synthetic alternatives
- Any visible changes may require ARB approval
Old Palo Alto
The Old Palo Alto neighborhood between Embarcadero, El Camino, and Oregon Expressway features primarily 1920s-1940s homes in various styles.
ARB Status: Most homes don’t have individual historic designation, but the neighborhood’s character influences city review.
Common Roofing Types:
- Spanish tile on Mediterranean homes
- Composition shingles on Tudor and Colonial styles
- Shake appearance on Craftsman homes
Key Considerations:
- Less restrictive than Professorville but still character-sensitive
- Tile-to-tile replacement straightforward
- Material changes may require design review
Crescent Park
Crescent Park, with its curving streets designed by Thomas Church, features larger lots and diverse architectural styles from the 1920s through 1960s.
Common Roofing Types:
- Mix of tile, shake-style, and composition
- Some flat sections on mid-century designs
- Estate-quality materials on larger homes
Key Considerations:
- Lot visibility affects review requirements
- Large roof areas make material selection visually significant
- Mid-century sections may require flat roof specialists
Eichler Neighborhoods
Palo Alto contains significant Eichler developments, particularly in the Charleston Meadows and Greenmeadow areas.
Roofing Type: Original tar-and-gravel converted to foam systems
Key Considerations:
- Flat roof specialists required
- White coatings meet Title 24 and maintain mid-century aesthetic
- Skylights common and require careful flashing
- No ARB concerns for routine recoating

Architectural Review Board Process
When ARB Review Is Required
Not every Palo Alto roof project requires ARB approval, but many do:
ARB Review Likely Required:
- Properties with individual historic designation
- Material changes visible from the street
- Color changes significantly different from existing
- Alterations to distinctive architectural features
ARB Review Usually Not Required:
- In-kind replacement (same material and color)
- Routine maintenance and repair
- Eichler flat roof recoating
Uncertain Cases: The Planning Department can provide determination letters clarifying whether your project requires review.
The Review Process
For projects requiring ARB review:
-
Pre-Application Meeting: Optional but recommended. Staff provides preliminary feedback before formal submission.
-
Application Submission: Complete application with:
- Site photos showing existing roof
- Material samples or specifications
- Color selections
- Drawings if roof lines are changing
-
Staff Review: Planning staff reviews for compliance and prepares staff report.
-
ARB Hearing: Board reviews application at public meeting. Straightforward material replacements often receive staff-level approval without full hearing.
-
Approval and Conditions: If approved, conditions may specify exact materials, colors, or installation details.
Timeline Expectations
- Staff-level approval: 2-4 weeks
- ARB hearing required: 6-8 weeks
- Complex or contested projects: 2-3 months
Start the process early. ARB schedules fill quickly, and holiday periods create gaps.
Improving Approval Chances
Do:
- Research your home’s architectural style and period
- Choose materials appropriate to that style and era
- Provide photo examples of similar historic homes with the proposed material
- Attend the pre-application meeting
Avoid:
- Materials clearly inappropriate to the period (modern metal on a Victorian)
- Colors that clash with neighborhood character
- Proposals that alter distinctive features without justification
Material Options for Historic Homes
Synthetic Slate and Shake
For homes originally roofed with wood shake or slate, synthetic alternatives provide historic appearance with modern performance:
DaVinci Roofscapes: Premium synthetic slate and shake in multiple profiles. Excellent for Professorville Victorians needing shake replacement.
Brava Roof Tile: Composite tiles mimicking slate, shake, or Spanish tile. Good for Old Palo Alto Mediterranean homes.
CertainTeed Grand Manor: Highest-profile composition shingle approximating shake appearance. Appropriate for Craftsman homes.
Benefits:
- Class A fire rating (required for shake replacement)
- Period-appropriate appearance
- 50-year warranties common
- Lower maintenance than natural materials
Clay and Concrete Tile
For Mediterranean, Spanish Colonial, and Mission-style homes:
Clay Tile: Authentic to the period and highly durable. Ludowici, MCA, and US Tile offer historically accurate profiles.
Concrete Tile: More affordable with similar appearance. Eagle and Boral provide excellent options for Spanish-style homes.
Restoration Approach: Existing tile often lasts 75+ years. Tile lift-and-relay preserves original tiles while replacing failed underlayment.
Architectural Shingles
For homes where composition shingles are appropriate:
Premium Profiles: GAF Grand Canyon, Owens Corning Berkshire, and CertainTeed Grand Manor offer dimensional appearance suitable for historic neighborhoods.
Color Selection: Earth tones (browns, grays, weathered wood) typically gain easier approval than blacks or unusual colors.
Copper Accents
Historic homes often featured copper:
Applications: Valleys, flashings, bay window roofs, turret caps, decorative elements
Approach: Preserve original copper where possible. Match patina on new sections. Use proper techniques to prevent galvanic corrosion.
Working with the City
Building Permits
All roof replacements in Palo Alto require building permits, separate from any ARB approval:
Application: Online through the city’s portal
Requirements: Material specifications, contractor licensing, Title 24 compliance documentation
Timeline: 1-2 weeks for standard residential roofing
Coordination with ARB
If ARB approval is required, you’ll need ARB approval before the building permit is issued. The planning and building departments coordinate, but allow time for both processes.
Tree Protection
Palo Alto has strict tree protection ordinances. If your roofing project requires equipment or staging near protected trees:
- Tree protection plan may be required
- Arborist consultation recommended
- Root zone protection during work
- No pruning without separate approval
Cost Considerations
Historic home roofing typically costs more than standard residential projects:
Material Premiums:
- Synthetic slate/shake: 50-100% more than standard shingles
- Clay tile: 100-200% more than concrete tile
- Custom copper work: Premium varies widely
Labor Factors:
- Complex roof geometries common on historic homes
- Careful preservation techniques required
- Some original materials need special handling
ARB Costs:
- Application fees: $500-$2,000 depending on project
- Design professional assistance if needed: $1,000-$5,000
Budget Ranges for Palo Alto historic home roofing:
| Project Type | Typical Range |
|---|---|
| Standard composition | $25,000-$45,000 |
| Synthetic slate/shake | $40,000-$75,000 |
| Tile restoration | $30,000-$60,000 |
| Full tile replacement | $50,000-$100,000 |
