Looking to install solar panels in Los Angeles? Choosing the right roof material is critical. LA’s intense sun, occasional heavy rain, and wind demand durable, weather-resistant options that can support solar panels effectively. Here’s a quick guide to the top five roofing materials perfect for solar panel installations:
- Asphalt Shingles: Affordable and widely used, with a lifespan of 20–30 years. Ideal for high temperatures but may need reinforcement for windy areas.
- Metal Roofs: Long-lasting and easy for mounting solar panels without drilling. Standing seam designs are especially suitable.
- Clay and Concrete Tiles: Durable against heat and strong winds but require specialized installation techniques for solar panels.
- TPO and EPDM Flat Roofs: Smooth, flat surfaces are perfect for even weight distribution and easy panel mounting. Lifespans range from 20–30 years.
- Solar Roof Tiles: Dual-purpose tiles with built-in photovoltaic cells, combining roofing and solar power in one.
Quick Tip: Always get a professional roof inspection before installation to ensure structural strength and compatibility with solar panels.
What Type Of Roof Is Best For Solar Panels? – CountyOffice.org
1. Asphalt Shingles
Asphalt shingles are a practical and budget-friendly choice for supporting solar panels in Los Angeles. Built with a fiberglass mat coated in asphalt and mineral granules, they offer protection from UV rays and can withstand Southern California’s tough weather conditions.
Life Expectancy
With proper care, architectural asphalt shingles can last 20–30 years. In Los Angeles, where summer temperatures often climb above 90°F, good attic ventilation can help them last longer. Installing solar panels can also help by shading the roof and reducing heat-related wear. Factors like proper ventilation, professional installation with even weight distribution, and regular upkeep are crucial to maintaining their durability under solar panels.
Benefits and Limitations
Asphalt shingles come with several advantages for solar panel setups in Los Angeles. They provide solid structural support, handle the region’s high temperatures well, and typically require minimal adjustments for mounting hardware. They’re also simple and affordable to install. However, in high-wind areas, such as hillside properties, additional reinforcement may be necessary to ensure both the roof and solar panels remain secure.
For the best results, experts recommend using architectural shingles with a Class A fire-resistance rating – an important feature in Los Angeles’s fire-prone areas. Next, we’ll take a look at metal roofs as another strong option for solar panel installations in LA.
2. Metal Roofs
Metal roofs are a solid choice for installing solar panels in Los Angeles. Their durable construction ensures they outlast solar panels while providing the strength needed to handle the added weight. Plus, they make mounting solar panels much easier.
Lifespan
Metal roofs can support solar panels for decades without losing their structural strength or reliability.
Solar Panel Mounting
Metal roofs are particularly well-suited for mounting solar panels. The standing seam design, commonly used in these roofs, allows for clamp-on mounting systems. This method eliminates the need to drill into the roof, reducing the risk of leaks and safeguarding the roof’s warranty.
Getting a professional evaluation is crucial.

3. Clay and Concrete Tiles
Clay and concrete tiles are a popular roofing option in LA, known for their ability to handle intense sunlight, heavy rain, and the powerful Santa Ana winds.
Weather Protection
These tiles are built to endure extreme heat, wet weather, and strong winds. Their sturdy design makes them a reliable base for solar panels, offering consistent protection against LA’s challenging weather conditions. However, installing solar panels on these tiles requires specific techniques.
Installation Requirements
Installing solar panels on tile roofs demands careful attention. Professionals evaluate the condition of the tiles, use mounting systems designed specifically for clay and concrete, and seal all mounting points to maintain the roof’s structure and prevent damage.
4. TPO and EPDM Flat Roofs
TPO and EPDM flat roofs are a common choice in Los Angeles for solar panel installations. Their smooth, uninterrupted surfaces not only look sleek but also provide the strength needed to support solar arrays.
Expected Lifespan
When installed correctly and maintained regularly, TPO roofs typically last 20–25 years in Los Angeles, while EPDM systems often reach up to 30 years. These roofs are built to handle the region’s intense sunlight and occasional heavy rain, making them a reliable option for long-term use.
This durability makes them a strong match for supporting solar panels.
Solar Panel Support
The flat design of TPO and EPDM roofs makes them ideal for solar panel setups. They allow for secure mounting and distribute weight evenly. Key factors to keep in mind during installation include:
- Using penetration-free, ballasted racking systems
- Spacing panels to ensure even weight distribution
- Designing layouts that maintain proper drainage and allow for easy inspections
Leaving enough space between solar panel rows ensures access for repairs and helps prevent water pooling, which is crucial for protecting the roof’s condition.

5. Solar Roof Tiles
Solar roof tiles combine the functionality of roofing with the benefits of solar power. Each tile is equipped with photovoltaic cells, making them ideal for Los Angeles’ intense heat, strong UV rays, and occasional rain. This all-in-one option provides a streamlined way for homeowners to address both roofing and energy needs.
Combined Roofing and Solar Power
What sets solar roof tiles apart is their dual-purpose design. The photovoltaic cells are integrated directly into the roofing material itself. Prime American Roofing offers expert guidance to help homeowners determine if these tiles are a good fit based on their roof’s orientation and the local climate.
Conclusion
Choose roofing materials that suit Los Angeles’ climate, durability needs, and long-term performance goals. Options like asphalt shingles and solar roof tiles cater to the city’s specific weather patterns and energy considerations.
Getting a professional evaluation, including a detailed roof inspection, is key to finding the right solution for your property. This process assesses structural strength, material compatibility, and the best placement for solar panels, ensuring a smooth and effective installation.
