A historic roof is more than just a functional part of a building—it tells a story, represents craftsmanship from another era, and preserves the integrity of a property’s original design. For business owners in The Triangle, maintaining a historic structure isn’t just about aesthetics; it’s an investment in longevity and value.
Restoring a historic roof comes with unique challenges, and missteps can lead to expensive repairs, regulatory issues, and even irreversible damage. Before starting your project, here are five common mistakes to avoid.
1. Using Modern Materials That Don’t Match the Original
One of the biggest mistakes in historic roof restoration is replacing original materials with modern alternatives. While newer roofing materials may seem more affordable or convenient, they often lack the durability and aesthetic compatibility of traditional options. Many historic buildings in Raleigh, Durham, and Chapel Hill have roofs made of slate, clay tiles, or wood shakes, materials chosen for their longevity and distinct character. Swapping these for asphalt shingles or metal panels can diminish the property’s historic value.
Why it’s a problem:
- Modern materials may not be compatible with the building’s structure.
- Using the wrong materials can change the look of the building, reducing its historical significance.
- Many historic districts have strict material requirements, and using the wrong one can lead to expensive rework.
How to avoid it:
- Work with suppliers that specialize in historic roofing materials to ensure an accurate match.
- Review historic records or old photographs to determine the original roofing material.
- Check local preservation requirements before purchasing materials. Many districts, including Downtown Durham and Chapel Hill, have regulations that specify permitted materials.
The Durham Historic Preservation Commission and the Raleigh Historic Development Commission provide clear guidelines for business owners restoring historic properties.
2. Skipping a Professional Roof Assessment
Some business owners assume that if a historic roof looks intact, it doesn’t need an inspection before restoration. But historic buildings often hide structural issues that aren’t visible from the outside.
Why it’s a problem:
- Hidden damage like rotting wood, deteriorated flashing, or compromised drainage systems can go unnoticed until restoration is underway, leading to unexpected costs.
- If underlying issues aren’t addressed first, even a newly restored roof can fail prematurely.
How to avoid it:
- Hire a roofer with experience in historic restorations to conduct a detailed evaluation before work begins.
- Ensure the assessment includes structural integrity, flashing, ventilation, and drainage.
- Budget for potential surprises—older buildings often require additional work once layers are removed.

3. Overlooking Local Preservation Guidelines
Restoring a historic roof isn’t just about craftsmanship—it’s also about compliance. Many business owners underestimate the importance of following local historic preservation regulations, which can result in fines, forced modifications, or legal issues.
Why it’s a problem:
- Many historic districts in Durham, Raleigh, and Chapel Hill have specific roofing guidelines. If work doesn’t meet these standards, you could be required to redo the project.
- Some materials and installation techniques may be prohibited.
- Not following local codes can affect a building’s historic designation and eligibility for preservation grants or tax credits.
How to avoid it:
- Research historic preservation office regulations before starting the project.
- Work with a contractor familiar with historic district rules who can guide you through the approval process.
- Obtain permits and approvals before beginning any modifications.
The City of Raleigh Historic Preservation Office and the Chapel Hill Historic District Guidelines outline specific requirements for businesses in historic areas.
4. Attempting a DIY Restoration or Hiring the Wrong Contractor
Historic roofs require specialized skills and materials. While modern roofing can be a straightforward job for general contractors, historic properties demand expertise in traditional building techniques.
Why it’s a problem:
- Delicate materials like slate and clay require careful handling. Improper installation can cause cracking or leaks.
- Incorrect repairs can compromise the structure, leading to premature failure.
- Historic roofs often have unique support structures, drainage systems, and fasteners that must be preserved.
How to avoid it:
- Work with a contractor experienced in historic roofing and ask for references.
- Review the contractor’s portfolio to ensure they have completed similar restoration projects.
- Make sure the contractor understands local preservation rules to avoid compliance issues.

5. Neglecting Long-Term Maintenance Needs
A well-restored historic roof is an investment, but without routine maintenance, its lifespan can be drastically shortened. Business owners often focus on the restoration itself while overlooking the ongoing care that these roofs require.
Why it’s a problem:
- Small issues like cracked tiles, loose flashing, or clogged gutters can escalate into major damage if ignored.
- Using incorrect cleaning methods can erode or discolor historic materials.
- Improper water drainage can lead to structural deterioration over time.
How to avoid it:
- Schedule regular inspections with a professional who understands historic materials.
- Keep gutters clear to prevent moisture buildup that accelerates decay.
- Use preservation-friendly cleaning techniques. Avoid power washing or harsh chemicals that could damage delicate roofing materials.
