What Type of Roof Material Is Best for Solar Panels?
If you’re thinking about going solar, your roof plays a big role. Not all roofs are created equal when it comes to solar panel installation. The type of material, slope, and even the age of your roof can impact how well solar panels work. In this guide, we’ll break down the best roof materials for solar panels, what to consider before installation, and how to make your roof solar-ready.
Why Roof Type Matters for Solar Panels
The roof is the foundation for your solar panel system. It needs to be strong enough to support the weight of the panels and durable enough to last for the 25-30 year lifespan of most solar installations.
How Roofing Material Impacts Solar Efficiency
The material of your roof affects how solar panels are installed and how much energy they produce. Some provide better weight support, while others affect panel efficiency due to their reflectivity and heat absorption. Homeowners considering solar roofing panels should evaluate how their roof material influences:
- Installation ease
- Panel longevity
- Structural integrity
- Energy production
Roof Strength and Durability Considerations
Solar panels add weight to your roof, about 2-4 pounds per square foot. Your roof needs to handle this extra load without compromising its structure.
Tip: At RAR Energy, we always check your roof’s weight capacity before installation. Learn more about our process.
Best Roof Materials for Solar Panels
Asphalt Shingles: Affordable and Popular
Asphalt shingles are the most common roofing material in the U.S. and one of the easiest surfaces for solar panel installation. They are:
- Affordable
- Easy to install solar panels on
- Compatible with most mounting systems
Stat: Over 75% of U.S. homes have asphalt shingle roofs, making them the most popular choice for solar (SEIA).
Metal Roofs: Durable and Energy Efficient
Metal roofs, especially standing seam metal roofs, are one of the best choices for solar panels. They are:
- Long-lasting (40-70 years lifespan)
- Highly reflective, reducing cooling costs
- Compatible with solar panel mounting systems without drilling
Fact: Metal roofs shed snow easily, making them ideal for our winters.
Tile Roofs: Clay, Concrete, and Their Benefits
Clay and concrete tile roofs provide excellent durability, but they require specialized mounting brackets. Benefits include:
- Long lifespan (50+ years)
- High resistance to heat
- Aesthetic appeal
Stat: Tile roofs can last 50+ years, but installation costs are higher (DOE).
Flat Roofs: Pros and Cons for Solar Installations
Flat roofs are common for commercial buildings and allow for flexibility in solar panel placement using tilt racks. Considerations include:
- Requires a racking system for optimal sun exposure
- Easy to maintain and access
- May need additional waterproofing
Wood Shingles: Why They Aren’t Ideal
Wood shingles are rarely recommended for solar panel installation due to:
- Fire hazard concerns
- Low durability and weight-bearing capacity
- Compatibility issues with mounting brackets
Our Advice: If you have wood shingles, consider a roof upgrade before going solar.
What Is the Best Roofing Material for Solar Panels?
The best roofing material for solar panels depends on various factors, including your home’s location, budget, and energy goals. However, composite shingles (asphalt) and metal roofs consistently rank as top choices due to their durability, cost-effectiveness, and compatibility with solar panel systems
Comparing Materials: Cost, Lifespan, and Efficiency
When choosing the best roof for solar panels, consider these factors:
- Cost: Asphalt shingles are typically the most affordable option.
- Lifespan: Metal roofs last the longest, often 60-80 years.
- Efficiency: Metal and tile roofs can enhance solar panel efficiency due to their reflective properties.
- Installation ease: Asphalt shingles are the easiest for solar panel installation.
| Roofing Material | Installation Ease | Lifespan | Best Features |
| Asphalt Shingles | Easy | 20-30 years | Affordable, widely available |
| Metal Roof | Easy | 40-70 years | Durable, energy-efficient |
| Clay/Concrete Tile | Moderate | 50+ years | Heat-resistant, long lifespan |
| Flat Roof | Moderate | 25-50 years | Flexible solar panel placement |
| Wood Shingles | Difficult | 15-25 years | Aesthetic appeal but not solar-friendly |
What Type of Roof Is Best for Solar Panel Installation?
The best roof types for solar panels are metal and asphalt shingle roofs due to their ease of installation, durability, and compatibility with mounting systems.
Roof Slope and Solar Panel Performance
The angle of your roof affects how much sunlight your panels receive. In Minnesota, an optimal tilt angle for solar panels is around 30-45 degrees for year-round energy production.
Roof Age and Condition: Key Factors
If your roof is over 10-15 years old, consider replacing it before installing solar panels. Panels last 25+ years, and you don’t want to remove them for roof repairs.

Weight Capacity and Solar Panel Installation
Most residential roofs can support the weight of solar panels. However, it’s essential to have a professional assessment to ensure your roof meets the structural requirements for solar panels. At RAR Energy, we conduct thorough evaluations to ensure your roof can safely support a solar panel system
Can Solar Panels Be Installed on Any Roof?
Solar panels can be installed on most roof types, some are more suitable than others. Factors like roof material, age, slope, and structural integrity all play a role in determining if your roof is solar-ready.
How to Know if Your Roof Is Solar-Ready
To determine if your roof is solar-ready, consider:
- Check Age: Is your roof less than 10 years old?
- Assess Condition: Are there leaks or damage?
- Evaluate Weight Capacity: Can it handle the extra load?
Stat: Over 90% of homes can support solar panels with minor upgrades (SEIA).
Roof Upgrades for Better Solar Compatibility
If your current roof isn’t ideal for solar panels, consider these upgrades:
- Reinforcing the roof structure to support the weight of panels
- Replacing old or damaged roofing materials
- Installing a solar-ready roof when it’s time for a replacement
