What is the Best Type of Roofing Material in California?

California’s climate is unique in the United States, ranging from Mediterranean weather on the coast to arid desert in the east and alpine tundra in the north. Choosing the right roofing material for your home or business in California primarily depends on your local climate; a material that works well in one part of the state may not be a good option if you live in another.

Breaking down the different California roof styles can help you understand their benefits and drawbacks and find the best roofing materials for your property.

The Best Types of Roofing Material in California

California homes and business properties feature a wide range of different roofing styles, meaning there is no such thing as a California-style roof. Each roof type features different materials, from Mediterranean roof styles to more modern flat roof designs.

If you’re trying to find the best roof replacement materials, understanding how each material performs and which climates they are best suited for is crucial. Here’s a breakdown of the best types of roof materials for California homes:

Clay Tiles

Clay is a traditional choice of roofing material with over 10,000 years of history. They are traditionally associated with Mediterranean roof styles, such as homes with Italian or Spanish architecture.

Clay tiles are available in many types, forms, and colors, from standard unglazed terracotta to factory-fired glazes. Shapes include S-shaped mission tiles, pantiles, flat, curved Roman, and Double Roman.

Advantages of
Clay Tiles

Drawbacks of
Clay Tiles

Durable and resistant to rot; can last more than 100 years Higher upfront cost; prices range between $12 and $25 per square foot


Minimal maintenance needed; debris removal and regular inspections Not suitable for flat or low-angle roofs
Thermally efficient, natural home insulation; reduces reliance on HVAC Requires a strong roof structure to manage the weight of the clay


  • Durability and long lifespan. Clay is a hard and durable material that cannot rot, catch fire, or sustain damage from pests like rodents. It also doesn’t retain moisture, making it resistant to mold and mildew. A properly maintained clay tile roof can last 100 years or more.
  • Low maintenance. The natural durability of clay tiles means they require very little maintenance after installation. The most common maintenance tasks are cleaning debris and periodic inspections to check for broken or missing tiles.
  • Thermally efficient. Clay is a natural insulation material, stabilizing your home’s indoor temperature and helping you meet California’s cool roof standards.
    The outside of a clay tile, especially with a light-colored glaze, reflects sunlight efficiently, keeping excess heat out of your home in the summer. During the winter, clay tiles trap heat inside the roof, ensuring it doesn’t escape. These properties help ensure you spend less on heating and air conditioning.


  • Higher upfront cost. The average cost of a square foot of clay tile ranges between $12 and $25. While this makes clay tiles pricier than other materials like asphalt or concrete, their lifespan can make them an excellent investment.
  • Unsuitable for flat or low-angle roofs. Clay tiles work best when installed on high or medium-slope roofs due to their weight and shape. Lower slope angles make it more challenging to prevent water from pooling on the clay tiles, adding weight. This issue can stress your roofing structure and accelerate wear and tear.
  • Requires a strong roof structure. Clay tiles are comparable in weight to concrete and heavier than most other tile and shingle materials. They require a well-designed roofing structure with appropriate reinforcements to support the load. Contact a roofing professional to check whether your roof can support clay tiles.

Concrete Tiles

Concrete tiles are durable, cost-effective, and popular in homes of all sizes and smaller commercial buildings. They are also among the most adaptable of roofing materials due to the large number of sizes, colors, and styles available. With the right colors and design, you can use concrete tiles to complement virtually any architecture or home design.

Advantages of
Concrete Tiles

Drawbacks of
Concrete Tiles

Cost-effective at around $2 to $4 per square foot on average, which can last 50 years Heavy tiles need a reinforced roof structure


Highly durable, resists impacts, fire, and harsh weather  Prone to fading from intense UV radiation
Eco-friendly materials and can be recycled


Not well-suited for cold climates; concrete can absorb water 


  • Cost-effective. One of the biggest benefits of choosing concrete tiles for your roof is price. On average, you can expect to pay $2 to $4 per square foot, making it one of the least expensive roofing materials. Despite the low price, concrete tile roofs last 50 years on average with proper maintenance, making them highly cost-effective.
  • Highly durable. Concrete tiles are among the most durable roofing materials available. They are impervious to rot or fire, resist impacts well, withstand the harshest weather conditions, and do not provide a suitable environment for mold and mildew to spread.
  • Eco-friendly material. The materials used to produce concrete tiles are often recycled. Additionally, concrete roofs reaching the end of their life can be recycled again, such as new tiles. These properties make concrete tiles a sustainable material choice.


  • Heavy tiles. Like clay tiles, concrete is heavy and requires a sufficiently strong roof structure with proper reinforcing. A roofing professional can inspect your roof and help determine its suitability for concrete.
  • Colors can fade under intense sunlight. While modern concrete tiles are made with fade-resistant paints and finishes, harsh sunlight can cause them to wear out more quickly. If your home or commercial building is in a warmer part of California, these factors can affect its value and curb appeal.
  • Less suited for cold climates. Concrete is a porous material, meaning it can absorb some water. In colder climates, the water inside concrete tiling can freeze and thaw, causing the tiles to crack. This phenomenon can increase your roof maintenance costs, as you may need to replace broken tiles more often.

Flat Roofing with Membranes

Buildings featuring flat roofs, such as apartment blocks, modern homes, and commercial buildings, typically feature a protective membrane on the roof’s surface. This membrane helps protect the roof from the elements, seals gaps, and seams, and enhances its durability.

Common membrane materials include PVC, TPO, and EPDM. The cost per square foot varies between $3.50 and $14, depending on the material selected.

Advantages of Membranes

Drawbacks of Membranes

All membrane materials are waterproof and prevent pooling Shorter lifespan than many other roofing materials; between 10 and 50 years


Durable and weather-resistant, including snow and strong winds


Dark-colored membranes can reduce the roof’s thermal efficiency
Flexible membranes are resistant to temperature changes to prevent cracking  Vulnerable to punctures from branches, building equipment and foot traffic 


  • Waterproof. All membrane materials are designed to protect the building from water infiltration. They are impervious to water or snow and can help prevent the formation of water pools.
  • Durable and weather-resistant. Besides water and rain, membrane materials are designed to withstand harsh weather, such as strong winds, snow, or UV rays from harsh sunlight. These properties make membranes weather-resistant in nearly every climate in California.
  • Resistant to temperature changes. Membranes are naturally flexible, accommodating the building’s structural movements as temperature fluctuates. They do not crack or tear under intense cold or heat.


  • Shorter lifespan. Although the lifespan of a membrane roof depends on the exact material used, it is typically shorter than classic tiles and shingle roofs. On average, EPDM membranes last 10 to 15 years, TPO membranes last up to 30, and PVC can last up to 50 with proper maintenance.
  • Thermal efficiency considerations. While you can order membranes in virtually any color to fit branding or architectural needs, darker-colored membranes absorb heat more easily than lighter-colored ones. This can be a disadvantage in the summer and in hotter regions of California.
  • Vulnerable to punctures. Foot traffic, tree debris, or maintenance equipment can puncture or damage flat roof membranes, rendering the home more vulnerable to water infiltration. Even the most resistant materials, like EPDM, are not fully impervious to damage from sharp objects and impacts.
