Roof Installation for Historic Homes in Swarthmore PA: What Every Homeowner Needs to Know

Swarthmore is known for its charm. The tree-lined streets, century-old architecture, and well-preserved homes give it a timeless appeal that stands out in Delaware County. But when it comes to something as essential as a new roof, that charm can come with a fair share of restrictions.

Roof installation for historic homes in Swarthmore PA isn’t as simple as picking a shingle and scheduling a crew. Between local preservation codes, material limitations, and the need to protect the original aesthetic of the house, the process requires careful planning and expert guidance.

Whether you’re dealing with a slate roof that’s seen better days or you’re navigating zoning approvals for an upcoming replacement, this guide will walk you through what to expect, what to avoid, and how to do it the right way.

 

Why Historic Homes Require a Different Approach to Roofing

Historic homes aren’t like modern builds. They were constructed with different materials, framing techniques, and roof pitches. Many use slate, wood shakes, or copper flashing, which aren’t always readily available today. Swapping those out for modern asphalt shingles might be cheaper and faster, but it can damage both the value and character of the home—not to mention possibly violate local regulations.

In a place like Swarthmore, where historic districts are tightly regulated, that’s a risk you don’t want to take.

 

Understanding Local Preservation Guidelines in Swarthmore

Before a nail ever hits your roof, you’ll want to get familiar with Swarthmore’s local preservation rules. These guidelines are in place to maintain the visual integrity of homes in designated historic areas.

Some common requirements include:

• Using like-for-like materials: If your home originally had slate, the borough may require that you replace it with slate or a similar high-end composite.

• Maintaining original rooflines: Raising the roof, altering the pitch, or adding dormers may not be allowed without approval.

• Color limitations: You might be restricted to historically accurate colors.

• Getting permits: In many cases, you’ll need approval from the Historical Architectural Review Board (HARB) before starting any roofing project.

Failing to comply can result in fines or forced removal of unapproved work. Always double-check with the local zoning office before signing any contracts.

 

Roofing Materials That Preserve Character (and Comply with Code)

Finding the right material is a balancing act between authenticity, durability, and budget. Here are some materials Swarthmore homeowners should consider:

1. Natural Slate

• Pros: Long lifespan (up to 100 years), unmatched historic accuracy, fireproof

• Cons: Expensive, heavy, requires expert installation

Slate is common on many of Swarthmore’s older homes and is often required in designated historic zones.

2. Synthetic Slate

• Pros: Lighter, more affordable, visually similar to real slate

• Cons: May not last as long as natural slate

Some historic commissions approve this as a viable alternative if natural slate is cost-prohibitive.

3. Cedar Shake/Shingles

• Pros: Period-appropriate, rustic appearance, good insulator

• Cons: Requires regular maintenance, susceptible to rot in humid conditions

Wood shakes are often used on colonial or farmhouse-style homes in the region.

4. Standing Seam Copper Roofing

• Pros: Durable, elegant, naturally patinas over time

• Cons: Very expensive, may only be used on porches or accent areas

Copper roofs or accents are historically accurate for many Victorian homes in the borough.

5. Architectural Asphalt Shingles (Historic Colors)

• Pros: Affordable, available in historic profiles and colors

• Cons: May not be allowed on certain homes

When allowed, these can mimic wood or slate at a fraction of the price—but they must be chosen carefully.

 

Challenges Homeowners Face During Roof Installation in Swarthmore

Installing a roof on a historic home can be an uphill battle. Here are the most common problems homeowners run into:

1. Approval Delays

Waiting on historic commission approval can push timelines back by weeks. Always budget for the extra time.

2. Limited Contractor Options

Not every roofer knows how to handle historic structures. You’ll want a roofing contractor near you who has experience with preservation standards.

3. Higher Material Costs

Premium materials like slate or copper don’t come cheap—and sometimes you don’t have a choice.

4. Structural Concerns

Older homes may need reinforcement to handle modern roofing systems. Rotted decking, outdated framing, and insufficient ventilation are common issues.

5. Matching Aesthetics

If your home has partial roof repairs or additions, matching the look perfectly can be tricky.

 

Choosing the Right Contractor for Historic Roof Installation

You need more than just someone who knows how to swing a hammer. Look for a licensed roofing contractor in Delaware County PA who:

• Has experience with roof restoration for historic homes

• Understands Swarthmore’s zoning and permit processes

• Can recommend historically accurate materials

• Offers references from other local homeowners

• Works with preservation experts or architects

A true professional will help you balance performance, appearance, and code compliance.

 

What to Expect During the Roof Installation Process

Here’s how a typical project plays out when dealing with a historic home:

Step 1: Inspection and Evaluation

A reputable roofer will thoroughly inspect the current roof, attic, and framing. They’ll look for signs of water damage, old ventilation issues, or structural concerns.

Step 2: Material Selection

You’ll work with the contractor and possibly a historical consultant to choose appropriate materials.

Step 3: Permit Approval

Before anything starts, expect paperwork. You may need to submit material samples, architectural drawings, or photos of nearby homes.

Step 4: Installation

Once approved, the crew will carefully remove the old roof and begin installation. Expect the process to take a little longer than usual to protect historic features.

Step 5: Final Inspection

In historic districts, a post-project inspection may be required to ensure compliance.

 

Tips to Preserve Your Home’s History While Modernizing Its Protection

• Don’t skimp on ventilation: Many old roofs are poorly vented, which shortens their lifespan. Add ridge vents or soffit vents where allowed.

• Upgrade underlayments: Modern synthetic underlayments offer better moisture protection without changing the roof’s appearance.

• Keep original trim and flashing: Whenever possible, preserve or replicate original details around dormers, chimneys, and eaves.

• Take photos before work begins: This helps with permitting and ensures details are recreated accurately.

 

Common Mistakes to Avoid

• Choosing a low-bid roofer without experience in historic homes

• Skipping the permit process

• Using off-the-shelf materials from big box stores

• Assuming synthetic materials are always allowed

• Neglecting structural assessments

 

Roof Maintenance Tips for Historic Homes

Once your roof is installed, keeping it in shape is key to protecting your investment:

• Schedule annual inspections (especially after storms)

• Keep gutters clean to avoid water backup

• Trim nearby trees to prevent branch damage

• Address minor leaks or loose slates immediately

• Document repairs for future resale or historical compliance
