If you're thinking about solar for your home or business, one of the most important things you need to understand is solar flashing. What are solar flashings? Why do you need them? And what are the different types? In this blog post, we'll answer all those questions and more. So read on to learn everything you need to know about solar flashing!
What is solar flashing?
Solar flashing is a waterproof barrier that is installed around solar panels to prevent water from leaking into the home or business. Solar flashings are essential in areas where there is a lot of rain, snow, or ice. Without solar flashings, water can leak into the home or business and cause damage to the structure, typically throughout areas such as edges, joints, or even gaps.
Flashing is typically installed after you implement the mounting system, and choosing the highest quality solar roof flashing is essential to ensure that you won't have any leak damage from materials that have deteriorated earlier than they should have. In addition, when you use the proper solar flashing, your roof will naturally expand and contract when exposed to various temperatures without impacting the quality of the seal while also ensuring your roof maintains a clean and finished look.
The 5 Most Common Types Of Solar Flashing
When it comes to choosing your solar flashing, there are a few different options to consider. Here are the five most common types of solar flashing:
Copper Solar Flashing

Copper Solar Flashing is one of the most popular options because it's durable and has a long lifespan. Copper is also a material that is easy to work with, so it's ideal for those who are doing a DIY solar installation. While copper is a more expensive option, it's worth the investment because it will last for many years.
The downside to copper is that it can develop a green patina over time. While this may not be a problem for some, others may prefer the look of Stainless Steel or Aluminum.
Aluminum Solar Flashing
The most used solar flashing option is aluminum because it doesn't rust and is cost-effective. Aluminum is also lightweight, so it's easy to work with during the installation process. However, while aluminum solar flashing is a great option, it's not as durable as copper and will need to be replaced more often.Aluminum flashing is installed by placing the flashing under the solar panel and then attaching it to the roof with nails or by using the weight of the roofing material.
Galvanized Solar Flashing
Galvanized Solar Flashing is typically more rigid than other solar flashing options, making it an excellent option for those looking for a strong material that will work well, especially when exposed to areas with high winds. The galvanized steel also gives it a clean look that some prefer over copper or aluminum.
While galvanized solar flashing is a great option, it can be more challenging to work with because of its rigidity and weight. And like aluminum, it's not as durable as copper or stainless steel.
Stainless Steel Solar Flashing
Last but not least is Stainless Steel Solar Flashing. This is an excellent option for those looking for durability and a clean look. Stainless steel won't corrode or rust and is easy to work with. However, it's important to note that stainless steel can be more challenging to cut than other materials.
When it comes down to it, each type of solar flashing has its own pros and cons. Therefore, it's essential to take the time to research each option and decide which one is right for you and your project.
Quick Solar Flashing Installation Tips
Now that you know the basics of solar roof flashing, here are a few quick tips to help make your installation go smoothly:
- Make sure you measure the area where you'll be installing the solar panels before you order your flashing. This will ensure you get the right size and avoid any problems during installation.
- If you're working with a contractor, make sure they are familiar with installing solar panels and understand the importance of proper solar flashing installation.
- Be sure to follow the manufacturer's instructions when installing your solar flashing. This will help ensure a proper seal and avoid any leaks.
- If you're doing a DIY installation, take your time and be careful. It's essential to get the flashing installed correctly to prevent leaks or damage to your property.
- Once your solar panels are installed, be sure to check the flashing and sealant around the panels regularly. This will help ensure your investment is protected for years to come.
