Architectural shingles, also known as dimensional or laminate shingles, are generally compatible with rooftop solar racking systems. These shingles are thicker and more durable than basic 3-tab shingles, which makes them better suited to support the hardware needed for solar panels. The layered design provides a sturdy base that can typically withstand the installation of solar mounts without compromising the roof’s integrity. However, because solar racking requires penetrating the roof to secure the mounts, installers must carefully waterproof around the attachment points to avoid leaks. If your architectural shingles are in good condition, with no cracking, curling, or significant wear, they should be a solid foundation for the solar system. Always check the roof’s age and overall health beforehand, as installing solar panels on a near-end-of-life roof can lead to complications later.
To safely assess your roof’s readiness for solar racking without calling a roofer immediately, visually inspect the shingles for damage or deterioration. Look for any signs of aging, like granule loss, blistering, or loose shingles, since these issues can make the roof less able to hold mounting hardware securely. Check the attic for signs of leaks or water stains. If everything looks sound, reach out to a reputable roofing contractor who has experience working with solar installs. Good questions to ask include, “Have you installed mounts on architectural shingles before, and can you show examples?” and “Will the warranty on my shingles remain intact after the solar installation?” These help ensure the installer is knowledgeable about maintaining both the roof’s weatherproofing and warranty conditions while securing the solar panels safely.
