Choosing the right roofing material is pivotal when installing solar panels, as it influences not only the installation process but also the efficiency and longevity of the solar system. At Cloud Roofing, we specialize in providing informed guidance to homeowners and businesses looking to optimize their rooftops for solar panels. This blog post will dive into the most popular roofing materials, and uncover which offers the best support for solar panels.
Metal Roofing
Metal roofing stands out as an ideal candidate for those considering solar panels for their commercial or residential buildings. Known for its durability and long lifespan, metal roofing aligns well with the typical 25 to 30-year lifespan of solar panels, ensuring that both the roof and the solar installation can age together without the need for significant adjustments. Moreover, the ease with which solar panels can be installed on metal roofs—often without needing to penetrate the roof's surface—makes this combination a preferred choice for many environmentally conscious property owners.
Advantages
Durability and Longevity
Metal roofs can last 40-70 years, matching or exceeding the lifespan of solar panels, which means less worry about roof replacements.
Lightweight
Metal's lightweight nature puts less strain on building structures, an important consideration when adding solar panels.
Easy Installation
The raised seams on standing seam metal roofs allow for easy and secure attachment of solar panel mounts without drilling holes, preserving the integrity of the roof.
Reflectivity
Metal roofs reflect solar radiant heat, which helps keep buildings cooler in summer, reducing air conditioning costs and increasing the efficiency of solar panels.
Considerations
Cost
Metal roofing can be more expensive initially compared to other materials, but the long-term benefits often justify the investment.
Noise
Without proper insulation, metal roofs can be noisy during rainstorms, though this can be mitigated with additional insulation layers.
Asphalt Shingles
Asphalt shingles are the most commonly used roofing material in many regions due to their cost-effectiveness and wide availability. This popularity also extends to their use under solar panels. While not as durable as some other options, the ease of installation and the straightforward nature of integrating solar mounts with asphalt shingle roofing make it a viable option for many homeowners. The flexibility and repair simplicity of asphalt shingles offer additional appeal, allowing for easy maintenance and adjustments as needed throughout the lifespan of the solar panels.
Advantages
Popularity and Familiarity
Asphalt shingles are widely used, making it easy to find contractors skilled in both roofing and solar panel installations.
Cost-effective
They are one of the most affordable roofing materials on the market, making them accessible for a wide range of budgets.
Ease of Repair
Shingle roofs are relatively easy to repair, and finding matching shingles for replacement is straightforward.
Considerations
Shorter Lifespan
Typically, asphalt shingles last about 15-30 years, which might require a roof replacement during the lifetime of the solar panels.
Weight
While generally not an issue, the cumulative weight of shingles and solar panels might require assessing the structural support of older buildings.
Tile Roofing
Tile roofs, which include materials such as clay, concrete, and slate, provide a robust and aesthetically pleasing base for solar panels. These materials are celebrated for their classic beauty and exceptional longevity, often outlasting the solar panels themselves. However, tile roofing presents unique challenges in solar installation, primarily due to the delicate nature of the tiles, which requires specialized handling to prevent damage during installation. The weight of tile roofs also necessitates careful consideration regarding the structural support of the building.
Advantages
Aesthetic Appeal
Tile roofs are prized for their aesthetic look and can increase a property's curb appeal and value.
Durability
Both clay and concrete tiles are known for their durability, often lasting 50 years or more.
Considerations
Complex Installation
Installing solar panels on tile roofing requires specialized skills to avoid damaging the tiles, which can add to the installation costs.
Weight
Tile roofs are heavy, and adding solar panels increases the load. Structural assessments may be necessary to ensure the building can support this weight.
Cost
Tile roofing can be on the higher end of the cost spectrum, particularly for slate tiles.
Rubber (EPDM) Roofing for Flat Roofs
Advantages
Seamless Surface
Rubber roofs provide a smooth, seamless surface that is ideal for installing solar panels, especially on flat or low-slope roofs.
Weather Resistance
EPDM roofing is resistant to weathering, UV rays, and temperature fluctuations, providing a stable base for solar installations.
Considerations
Professional Installation Required
The installation of both EPDM roofing and solar panels on such surfaces should be handled by professionals to avoid punctures or leaks.
Periodic Maintenance
To maintain its integrity, a rubber roof may require periodic recoating or sealing, especially prior to solar panel installation.
