Installing solar panels is a great way to reduce your carbon footprint by harnessing the sun’s power for electricity. They’re one of the primary features of an eco-friendly home, but before you invest, several things must be considered.
If you are going to place the panels on top of your roof, you have to determine if it needs to be replaced first. The local roofing experts of MHI Roofing shed light on the matter.
The Need for Proper Planning
Solar panels are designed to last 25 to 30 years. Residential roofing systems can last just as long, though it will depend on the material and its expected life span. Generally, a roof can exceed the solar panel’s service life if it is well-maintained and can withstand constant exposure to the elements.
Installing the solar panels and removing them again to do roofing work is not just labor-intensive but also costly. Roof repair and replacement experts recommend that you check the roof’s expected life span first before you go solar. Replacing your current roof makes sense if it is nearing the end of its service life.
Solar Panel Installation on Various Roof Coverings
If asphalt shingles are your choice for your replacement roof, expect the solar panel installation to involve drilling into the roof covering and attaching mounting hardware to roof studs. These penetrations are then sealed off to stop water from seeping through the roof. Meanwhile, proper care must be observed for a tile roof to avoid damage. Pieces of tiles are removed to make way for brackets, which are installed with flashing to prevent leaks.
A standing seam metal roof, however, is the best for solar panel installations for many reasons. It is designed to last between 40 to 70 years, which exceeds solar panels. It is also easy to maintain, leading to long-term cost savings. There’s no need for penetrations—the seams of the roof can be used for mounting hardware for the solar panels.
At Meredith Home Improvements, we install the GF DecoTech® Solar Roofing System, a low-profile solar panel system that installs directly into your roof. Unlike rack-mounted solar panels, they won’t disturb the integrity of your roof and guard against moisture and leaks.
