When seeing Solar PV Systems, it’s probably most common that most people see it in its finished form, where the focus is the panel itself. Underneath those panels is one of the essential pieces is the PV System: the mounting attachments. For most roofs, it is vital to have appropriate flashing before solar panel installation. Without a type of flashing solar attachment, a roof isn’t airtight and is susceptible to water leakages that could lead to a trajectory of issues that can severely damage a home.
Flashing Vs. Flashing-Free
Flashing is done by carefully attaching a flexible yet sturdy metal meant to redirect water downward on the roof. It prevents water from seeping into a roof while ensuring the PV system is secured on the surface of its roof.
Things to consider when using Flashing:
Ensure you or your solar installer are careful and have thoroughly read and understood the manual before installation.
Double-check that you are using the equipment recommended by the manufacturer.
Research to make sure that the pieces you are purchasing are up to standard and later installed correctly according to industry standard.
Ensure that the product is of high quality from a trusted manufacturer that are experts in the industry. For example, we provide UNIRAC’s FlashKit Pro that is TAS-100 and UL-441 certified. The kit contains three parts, the only components needed for its installment ensuring installation is simple yet sturdy.

Although flashing is the most widely accepted method of mounting PV systems, Flashing-Free solar attachments are growing in popularity. Its ease of installation is a winning factor for this method. Even with increasing demand, some Authorities Having Jurisdiction (AJHs) may not be fully aware of this system, so further documentation may be necessary.
Things to consider for Flashing-Free:
If using a direct-to-deck mount, you may need more equipment compared to a Flashing mount. While the ease of installation saves time, you may have to compensate for having to purchase more mounts in addition to labor time.
Ensure that the product you are using isn’t requiring you to handle sticky material that could complicate the installation process directly.
It is crucial to make sure your purchase is certified to TAS-100 Wind-Driven Rain Test and UL-441 Rain Test and is using trustworthy material.
Like flashing, you should always ensure that a dependable and reputable solar manufacturer produces the Flashing-Free equipment you use. UNIRAC also has a Flashing-Free mounting option, FlashLoc. A simple three-step process to mounting solar modules.

During the process of Solar installation, it is essential not to deter attention away from the roof. Carefully attaching a Flashing or Flashing-free system can maintain its appearance, protect it from high wind and rain, and keep the PV array on the roof for as long as possible.
