Why "Modernizing" a Historic Roof is a Mistake
Quote from discountedroofingllc on January 13, 2026, 6:19 amThere is a prevalent trend in renovation to rip out the old and replace it with the "maintenance-free" new. DISCOUNTED ROOFING LLC is here to challenge that mindset, especially in our historic districts. Tearing off a 100-year-old slate roof to install asphalt shingles isn't an upgrade; it is a downgrade in value, aesthetics, and longevity. We believe that preservation is not just about nostalgia; it is about recognizing superior performance and engineering.
When approaching Roof Repair Philadelphia homeowners often hear from salesmen that slate is "too hard to maintain" or "too heavy." We challenge this. Slate is stone. It is literally the most durable roofing material on earth. A slate roof can last 150 years. An asphalt roof lasts 20. When you tear off slate, you are trading a permanent asset for a disposable liability that will end up in a landfill in two decades. The challenge is not the material; it is finding a craftsman who knows how to fix it. We advocate for surgical repairs—replacing only the broken tiles—rather than full replacement.
We also challenge the use of aluminum capping on historic cornices. Aluminum dents easily, fades quickly, and looks cheap against 19th-century brick.
We push for copper or terne-coated stainless steel. Yes, it costs more upfront. But copper has a lifespan measured in centuries, not decades. It develops a protective patina that self-heals and protects the metal. It honors the architectural intent of the building and raises the property value.
Furthermore, "modernizing" often breaks the ventilation of the home. Old homes were designed to "leak" air in a controlled way through the roof structure. Sealing them up with spray foam and non-breathable synthetic underlayments often leads to moisture rot in the roof deck because the house can no longer exhale. We challenge the industry to respect the original building science. Keep the skip sheathing. Use felt paper that breathes. Trust the methods that have kept the house standing for a century.
Don't downgrade your legacy for the sake of convenience. Restore it for the sake of the future.
