Why Is It Important To Use Flashing When Installing Solar?

What is flashing? Flashing refers to the strips of metal that are used to secure your solar panel system to the surface of your roof. Installing flashing when you install your solar panel system can act as additional protection for your roof and shingles, leaving them better protected from weather elements, corrosion and structural damage. Flashing is a good tool to prolong the life of your solar panel system for as long as possible.

The benefits of flashing are often misunderstood, however, they are vital for homeowners who wish to ensure that their solar panel systems are not a detriment to the lifespan of the roof itself. When flashing is installed correctly, it acts as a water barrier for added protection during seasonal precipitation. It is recommended that flashing be installed in an orientation that matches the surface of the roof in order to prevent rain or snow from soaking inwards.

Corrosion Protection

A typical solar panel system is usually made of up several metals including copper and steel, among others. The use of flashing during solar panel installation can prevent the occurrence of corrosion or rust on the surface of the panels or roof. In the long run, rust or corrosion prevention will result in the reduction of excess maintenance fees or serving that may be needed from time to time. The flashing doubles as an additional barrier between the solar panels and the roofing material–ensuring that your roof’s lifespan will not be burdened by the solar panel system.

Structural Integrity

For these reasons, it is critical that the structure can support the solar panel system properly. The use of flashing can assist in stabilizing the solar panels and ensuring that they are securely fastened to your rooftop. Flashing can provide the surface of your roof with additional support and prevent any damage from occurring. For optimal results, it is recommended that flashing be installed before solar panels and not afterwards as adding flashing after solar panels can compromise the structural integrity of your home.

Although they’re common in many parts of the world, solar panels have gained popularity in Canada over the past decade. The use of solar panels are a green alterative to the emission-ridden ways of the past, however, homeowners must be diligent to ensure that they get maximum use of out the system while incurring minimal costs.  The of flashing during installation has proven to protect the surface of the roof, preventing any damage to the panels or to the rooftop.
