Types of Roof Flashing Materials
Aluminum Flashing
Aluminum flashing is the most common type used in solar panel installations. It is lightweight and easy to handle, making it a popular choice. Aluminum flashing is installed by lifting the shingles and placing the flashing underneath. It helps redirect water away from roof penetrations. However, one downside is that it requires removing shingle nails, which can create additional holes in the roof.
Rubber Flashing
Rubber flashing, often made from EPDM, works alongside aluminum flashing. A rubber bushing is inserted into the aluminum flashing to create a watertight seal. This type of flashing is effective in preventing leaks but can be more expensive than aluminum. It is also installed under shingles and secured with nails.
Microflashing
Microflashing is a newer option that is much smaller than traditional flashing, typically measuring 3 to 4 inches in diameter. It uses a stainless-steel compression washer with EPDM to create a seal directly over the shingle. This method does not require lifting shingles, making it easier to install and handle.
| Type of Flashing | Weight | Cost | Installation Method |
|---|---|---|---|
| Aluminum | Lightweight | Low | Under shingles |
| Rubber | Moderate | High | Under shingles |
| Microflashing | Very Light | Moderate | No shingle removal |
Choosing the right flashing material is crucial for ensuring a watertight seal and preventing leaks in your solar panel installation.
Summary
Each type of flashing has its own advantages and disadvantages. Aluminum is cost-effective, rubber provides a strong seal, and microflashing offers ease of installation. When selecting flashing, consider factors like cost, weight, and installation method to find the best fit for your solar panel system.
