Choosing the Right Roofing Materials for Pennsylvania’s Climate
Pennsylvania’s diverse climate creates unique challenges for roofing materials. From the mountains in the north to the southeastern plains, homeowners face everything from heavy snow loads to severe summer storms. At Greenawalt Roofing Company, our 21+ years of experience across Pennsylvania, New Jersey, and Delaware has taught us which materials truly perform in our regional conditions. We want to share this knowledge to help you choose roofing materials that will protect your home for decades to come.
Understanding Pennsylvania’s Climate Challenges
Regional Weather Variations
Pennsylvania’s geography creates distinct climate zones that affect roofing material performance:
Northern Mountains (Pocono, Northern Tier):
- Heavy snow loads (100+ pounds per square foot)
- Extended freezing periods
- Extreme temperature swings (-20°F to 85°F)
- Ice dam formation potential
Central Valleys (Harrisburg, State College):
- Moderate snow loads with occasional heavy storms
- Freeze-thaw cycling throughout winter
- Summer temperatures reaching 95°F+
- Severe thunderstorms with hail and high winds
Southeastern Plains (Philadelphia suburbs):
- Moderate winter conditions with ice storms
- Hot, humid summers
- Hurricane and tropical storm potential
- Higher UV exposure
Common Weather-Related Roofing Problems
- Ice dam formation leading to water backup
- Thermal expansion and contraction stress
- UV degradation during long summer days
- Wind uplift during severe storms
- Moss and algae growth in humid conditions
Top Roofing Material Options for Pennsylvania
Asphalt Shingles: The Pennsylvania Standard
Asphalt shingles represent over 80% of Pennsylvania roofs for good reason. They offer the best combination of performance, cost, and local availability.
Why Asphalt Shingles Excel in Pennsylvania:
- Excellent thermal cycling performance
- Wide range of wind resistance options (60-150+ mph)
- Good snow load capacity
- Cost-effective for most budgets
- Easy repair and replacement
- Extensive contractor expertise available
Best Asphalt Options for Pennsylvania:
CertainTeed Landmark Series: Our most popular choice offers excellent performance in Pennsylvania conditions. The enhanced granule formulation resists algae growth and UV damage, while the strong adhesive system handles thermal cycling exceptionally well.
CertainTeed Grand Manor: For homeowners wanting premium aesthetics, Grand Manor provides authentic slate appearance with 50-year warranty protection. The heavy weight and enhanced wind resistance make it ideal for exposed locations.
CertainTeed Presidential Solaris: The ultimate in asphalt shingle technology, featuring solar reflective granules that reduce cooling costs and advanced weathering protection.
Metal Roofing: Superior Longevity
Metal roofing has gained popularity in Pennsylvania due to its exceptional lifespan and performance in extreme weather.
Advantages for Pennsylvania Homes:
- 50-70 year lifespan
- Excellent snow shedding properties
- Superior wind resistance (up to 180+ mph)
- Energy efficiency through reflectivity
- Fire resistance
- Lightweight reduces structural stress
Pennsylvania-Specific Benefits:
- Snow slides off easily, preventing ice dam formation
- Handles thermal expansion well
- Resists hail damage better than most materials
- Low maintenance requirements
Considerations:
- Higher upfront cost (2-3x asphalt shingles)
- Noise during heavy rain or hail
- Limited color options compared to shingles
- Specialized installation requirements
Best Metal Options:
- Standing Seam Steel: Premium choice with excellent weather resistance
- Metal Shingles: Combine metal durability with traditional appearance
- Copper: Ultimate luxury with 100+ year lifespan but very high cost
Slate: The Pennsylvania Heritage Choice
Natural slate has protected Pennsylvania homes for over 200 years. Many original slate roofs from the 1800s still perform today.
Why Slate Works in Pennsylvania:
- 75-100+ year lifespan
- Excellent freeze-thaw resistance
- Superior fire resistance
- Authentic historical appearance
- Minimal maintenance requirements
- Increases home value significantly
Pennsylvania Slate Advantages:
Pennsylvania actually produces some of the world’s finest slate in regions like Bangor and Pen Argyl. Local slate often outperforms imported options and supports regional economy.
Considerations:
- Very high upfront cost ($10-20+ per square foot)
- Requires structural evaluation for weight capacity
- Specialized installation expertise needed
- Individual tile replacement can be challenging
- Limited contractor availability
Clay and Concrete Tiles: Limited Regional Use
While popular in warmer climates, clay and concrete tiles face challenges in Pennsylvania’s freeze-thaw conditions.
Potential Benefits:
- 50-100 year lifespan
- Excellent fire resistance
- Energy efficiency through thermal mass
- Distinctive architectural appeal
Pennsylvania Challenges:
- Freeze-thaw damage potential
- Heavy weight requires structural reinforcement
- Higher installation costs
- Limited local contractor expertise
- Snow retention can cause ice dam issues
We generally recommend tiles only for specific architectural styles in protected locations with adequate structural support.
Wood Shakes and Shingles: Traditional Beauty with Limitations
Wood roofing offers authentic rustic appeal but requires careful consideration in Pennsylvania.
Advantages:
- Natural insulation properties
- Beautiful, authentic appearance
- Good performance in dry climates
- Renewable resource when sustainably sourced
Pennsylvania Challenges:
- Fire risk (often prohibited by local codes)
- Moss and algae growth in humid conditions
- Requires regular maintenance and treatment
- Shorter lifespan (15-30 years) in our climate
- Higher insurance costs
Wood shakes work best in rural areas with relaxed fire codes and homeowners committed to regular maintenance.
