CUSTOMER REVIEWS
Homeowners across Central Pennsylvania know that winter isn’t just about cold temperatures; it’s about heavy snow, ice buildup, and long stretches of freeze-and-thaw cycles that put severe pressure on your roof. Choosing the right roofing material isn’t just a design decision; it’s a performance and protection decision that can affect your home for decades. When comparing metal vs asphalt roofing, especially in terms of snow load roofing and long-term durability, there are clear differences worth understanding.
At Bull Run Roofing, we help homeowners make confident, informed choices by breaking down how each roofing system truly performs in Central PA’s winter climate.
How Snow and Ice Affect Roofing Systems
Snow may look harmless, but once it accumulates, it becomes extremely heavy. Wet snow typically weighs around 20 pounds per cubic foot or more, creating ongoing stress on your roof structure. Ice dams add another layer of risk, trapping moisture and forcing water beneath shingles or panels.
That’s why snow load roofing performance is so important in Central Pennsylvania. Your roof must be able to support weight, manage melting snow safely, and resist moisture intrusion throughout the winter season.
Metal Roofing Performance in Snowy Conditions
Metal roofing is still one of the sturdiest options for snow-heavy regions, and for good reason.
Snow Shedding Advantage
Metal panels have smooth surfaces that allow snow and ice to slide off a lot more easily than textured shingles. This reduces the amount of weight sitting on your roof at any given time and lowers the risk of structural strain.
Strength and Durability
Metal roofing systems are engineered to handle heavy snow loads and harsh weather. Properly installed metal roofs resist cracking, warping, and moisture absorption — all common winter-related issues.
Ice and Moisture Resistance
Because metal panels interlock and shed water efficiently, they are less vulnerable to ice dam damage. Snow melts faster on metal, minimizing freeze-back at roof edges.
Energy-Efficient Roof Benefits
Metal roofs reflect sunlight and regulate attic temperatures more effectively year-round. In winter, this helps reduce uneven heat loss that leads to ice dams, while also improving overall energy efficiency.
For residents planning to stay in their homes long-term or those prioritizing performance over initial cost, metal roofing offers exceptional winter reliability.
Asphalt Shingle Performance in Snowy Conditions
Asphalt shingles are still one of the most common residential roofing material in Central PA, and they can perform well in snow when properly installed and maintained.
Weight-Bearing Capability
Modern architectural asphalt shingles are designed to withstand snow loads common to Pennsylvania winters. However, snow tends to stay on asphalt roofs longer due to their textured surface.
Ice Dam Risk
Asphalt roofs are more susceptible to ice dams if attic ventilation or insulation is inadequate. Water can back up beneath shingles, leading to leaks and interior damage.
Cost and Repair Flexibility
Asphalt roofing is more affordable upfront and easier to repair if localized damage occurs. For homeowners on a tighter budget, it remains a practical and reliable option.
Energy Efficiency Considerations
While not as reflective as metal, asphalt shingles can still contribute to an energy-efficient roof when paired with proper ventilation, insulation, and quality underlayment.
Metal vs Asphalt Roofing: A Side-by-Side Winter Comparison
When evaluating metal vs asphalt roofing for snowy climates, here’s how they typically compare:
- Snow shedding: Metal performs better
- Snow load resistance: Both perform well when properly installed
- Ice dam prevention: Metal has a clear advantage
- Upfront cost: Asphalt is more affordable
- Long-term lifespan: Metal lasts significantly longer
- Energy efficiency: Metal offers stronger year-round efficiency
The “better” choice depends on your priorities, budget, longevity, and how much winter performance matters to you.
Gutters Matter More Than You Think
No matter which roofing material you choose, proper gutter systems are critical in snowy regions. Seamless gutters and gutter guards help control melting snow and ice runoff, preventing water from refreezing at roof edges or damaging your siding and foundation.
Bull Run Roofing installs seamless and K-style gutters designed to work in harmony with both metal and asphalt roofing systems, ensuring complete protection during the winter months.
Choosing the Right Roof for Your Central PA Home
Both metal and asphalt roofs can perform well in snowy conditions when installed correctly. Metal roofing excels in snow shedding, durability, and long-term efficiency, while asphalt shingles offer affordability and proven performance when paired with good ventilation and maintenance.
