Slate vs. Asphalt Shingles: A Lehigh Valley Guide

Driving through the historic districts of Easton or Bethlehem, you will see stunning slate roofs that are over 100 years old. But does that make them the right choice for your home replacement?

The Case for Slate

Pros: Longevity is king. A slate roof can last 75-150 years. It is fireproof, eco-friendly (natural stone), and increases resale value for historic homes.

Cons: It is incredibly heavy (requires structural reinforcement), expensive to install, and difficult to find qualified repair technicians.

The Case for Asphalt

Pros: Affordable, quick to install, and available in hundreds of colors. Modern architectural shingles mimic the look of slate or wood shake at a fraction of the cost.

Cons: Shorter lifespan (20-30 years) and vulnerable to moss and wind uplift.

The Verdict

If you own a historic property and plan to stay forever, restore the slate. For 95% of other homeowners, a high-quality architectural asphalt shingle is the best investment.
