Squirrel Hill in ZIP 15217 features some of Pittsburgh’s most striking historic architecture, with 1920s Stone Tudors and Colonial Revivals retaining original Pennsylvania Bangor slate roofs.
Maintaining slate requires specialized knowledge from a trusted Pittsburgh roofing contractor.
Why Historic Slate Survives Decades
Natural slate stone tiles can last over 100 years. However, individual tiles can slip when original iron fasteners corrode, or when tree branches fall on roof slopes.
Common Slate Maintenance Issues
- Rusted Nail Syndrome: Original iron nails rust away, allowing intact slate tiles to slide down roof valleys.
- Flashings & Valleys Wearing Out: While slate stone lasts over a century, original copper or valley metal wears thin after 60 to 80 years.
