How Solar Panels Are Installed On Your Roof
Being concerned about roof damage with a solar panels installation certainly isnt unreasonable. Putting racking and solar panels on your roof alter one of the core parts of your homes structural makeup, and there are parts to the installation process that put your roof at risk if done incorrectly.
One of the biggest concerns for property owners is the holes needed in your roof to secure your solar panels. During installation, workers will drill holes in your roof to secure the racking which will hold your panels. These holes are for lag bolts, which secure your panels to your roof, and are designed to withstand extreme weather. These holes and bolts are necessary for almost every solar installation, and their size and depth will vary based on what your roof is made of .
Holes in your roof never sounds great, but there are several safety measures used by solar installers to make sure your roof remains structurally sound and wont leak at all. To prevent water from getting through the new hole, the bolt fixture will be surrounded by flashing, which is a metal or plastic shield that fits under existing roof tiles. This flashing is then further sealed with tar or similar material. Lastly, the hole where the lag bolt is also filled with a sealant to protect against water seepage in your roof.
Can Any Potential Leaks Cause Damage
It is rare that you will experience any leaks due to solar panel installation. In case any leaks do arise contact your installer to check whether the repair will be covered under warranty. The best way to prevent any post-installation leaks is to have a professional evaluation by an installer beforehand.
Will Solar Panels Damage A Metal Roof
While they last several decades, metal roofs are a substantial investment. You dont want to do anything to cut the life of your roof short. Even if doing so will bring you decades of free electricity, like with solar panels.
However, as long as your solar panels are installed on par with industry standards, you wont be causing any short- or long-term damage to your roof. In fact, solar panels can actually protect your roof.
While theyre not indestructible, solar panels are designed and installed to withstand a pretty good beating from mother nature. Theyll act as a buffer, shielding your roof from the typical wear and tear over time.
When it comes to securing your solar panels to your metal roof, you can rest assured you wont be exposing your building to any leaks. Solar panels installed on standing seam roofs can typically be installed with no penetrations. Ribbed metal roofs will require penetrations. However, the bolting system is specifically designed to prevent leaks for the lifespan of your solar panel system.
