If you live in a sunny region with a Mediterranean or Spanish-style architecture, chances are you have a tile roof. Tile roofs are made of clay or concrete tiles that are durable, attractive, and eco-friendly. They can last for decades and withstand harsh weather conditions. But can you put solar panels on a tile roof?
The answer is yes, you can install solar panels on a tile roof, but it requires more care and expertise than other roof types. In this article, we will explain why tile roofs are challenging for solar installations, and what are the best ways to overcome these challenges.
Why Tile Roofs Are Popular and Problematic
Tile roofs are popular in areas with hot and dry climates, such as California, Arizona, Florida, and Texas. They have several benefits over other roofing materials, such as:
• They reflect heat and keep your home cooler in summer
• They resist fire, rot, insects, and mold
• They add aesthetic value and curb appeal to your home
• They are made of natural and recyclable materials
However, tile roofs also have some drawbacks, especially when it comes to installing solar panels. Some of these drawbacks are:
• They are heavy and may require additional structural support
• They are fragile and may break or crack during installation or maintenance
• They are expensive and may increase the cost of solar installation
• They create gaps between the tiles and the roof deck that may allow water to seep in
How to Install Solar Panels on a Tile Roof
Installing solar panels on a tile roof is not impossible, but it requires more skill and experience than other roof types. There are several methods and techniques that can be used to mount solar panels on a tile roof safely and securely. Some of these methods are:
• Tile cutting: This method involves cutting holes in the tiles where the solar mounts will be attached. This allows the mounts to go through the tiles and bolt directly to the roof deck. This method preserves the appearance of the tiles, but it may damage or weaken them.
• Tile hooks: This method involves using hooks that go under the tiles and attach to the roof deck. The hooks then support the rails and panels above the tiles. This method avoids cutting or breaking the tiles, but it may create gaps that need to be sealed properly.
• Tile replacement mounts: This method involves removing some tiles where the solar mounts will be placed. The mounts then replace the tiles and act as both mounting points and flashing. This method eliminates the need for cutting or drilling holes in the tiles, but it may reduce the aesthetic value of the roof.
• Double flashing: This method involves using two layers of flashing to seal the gaps between the tiles and the roof deck. The first layer is attached to the roof deck under the tiles, while the second layer is attached to the mount above the tiles. This method provides extra protection against water leakage, but it may increase the installation time and cost.
Which method is best for your tile roof depends on several factors, such as your budget, your preferences, your roof condition, and your local codes.
