Asphalt vs. Metal Roofs: Which is Best for Your Pennsylvania Home?
Compare materials, budget, and climate performance for your next exterior investment.

Pennsylvania weather demands a lot from your home’s exterior. Between freezing winter ice storms in the Perkiomen Valley and intense summer humidity, choosing the right roofing material is the most critical decision in your replacement project.
For most homeowners in Montgomery County, the decision comes down to the two industry leaders: modern architectural asphalt shingles and standing seam metal roofing. Here is a complete breakdown of how they compare, how they handle the local climate, and which one is the right investment for your home.
Architectural Asphalt Shingles: The Reliable Standard
Asphalt shingles are the most popular roofing material in North America, and for good reason. They offer an exceptional balance of affordability, versatility, and proven protection.
It is important to note that modern architectural shingles are vastly superior to the flat, 3-tab shingles of the past. Built with multiple layers of fiberglass and asphalt, they create a dimensional look that mimics wood shake while offering heavy-duty weather resistance.
- Wind Resistance: Premium architectural shingles are engineered to withstand severe weather, offering wind warranties up to 130 mph—more than enough to handle harsh Pennsylvania summer thunderstorms.
- Aesthetic Versatility: Available in dozens of color palettes, from classic warm tones to bold designer blends, making it easy to match your home’s unique curb appeal.
- Cost-Effective: Asphalt provides the lowest barrier to entry for a full roof replacement, offering excellent value for a 20 to 30-year lifespan.
- The Drawback: Asphalt absorbs heat during the summer and is more susceptible to the friction of ice and snow compared to smoother materials.
Standing Seam Metal Roofing: The “Lifetime” Upgrade
If you are looking for a “one-and-done” roofing solution, standing seam metal is the ultimate premium upgrade. Unlike exposed-fastener corrugated metal (which is better suited for barns), standing seam roofs feature interlocking panels with hidden fasteners, creating a sleek, impenetrable barrier.
- Unmatched Lifespan: A properly installed metal roof will last 40 to 70+ years. For many homeowners, this is the last roof they will ever need to buy.
- Winter Weather Performance: Metal roofs excel in PA winters. Their smooth surface allows heavy snow to slide right off, drastically reducing the risk of ice dams building up along your eaves.
- Summer Cooling: Instead of absorbing the summer sun, metal reflects UV rays, which can help keep your attic cooler and lower your seasonal HVAC costs.
- The Drawback: The initial investment is significantly higher than asphalt—often two to three times the cost. However, the lifespan and energy efficiency often offset this over the decades.

A Note on Flat Roofs: Low-Slope Membranes
If your home has a flat addition, a low-pitch porch, or a garage, neither asphalt nor metal is the right choice. Water moves too slowly off flat surfaces, which will cause standard shingles to leak.
For these specific areas, we utilize Low-Slope Membranes, specifically specialized TPO (Thermoplastic Polyolefin) or EPDM (rubber) systems. These materials are heat-welded or chemically adhered to create a single, monolithic, leak-proof barrier specifically designed to handle pooling water.
Choosing the right material ultimately comes down to your budget, your aesthetic preferences, and how long you plan to stay in your home.
