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.

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

- Understands Swarthmore’s zoning and permit processes
- Can recommend historically accurate materials
- Offers references from other local homeowners
- Works with preservation experts or architects
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
