Silicone roof coatings are popular for their durability, waterproofing, and UV resistance, making them a great choice for flat or low-slope roofs. However, when it comes to compatibility with rooftop solar racking, the main concern is whether the coating can withstand the physical stresses that come with mounting racks and panels. Silicone coatings are generally flexible and resistant to cracking, which helps maintain the roof’s waterproof barrier even with some movement or pressure. But solar racks require penetrations or mounting systems that can affect this integrity if not installed carefully. Simple visual inspections for any signs of silicone layer damage, such as tears, punctures, or lifting, can indicate potential issues. Homeowners can gently check around existing mount points for any signs of water intrusion or coating degradation, but avoid any aggressive probing that might further damage the coating.
If you’re considering solar panels on a silicone-coated roof, it’s wise to contact a roofing professional and a solar installer early in the process. They can evaluate your specific roof condition, coating thickness, and the solar rack design to ensure compatibility without breaking the warranty. When discussing with a contractor, you might ask: “How will you ensure the roof coating remains sealed around mounting points, and what warranty coverage is available if the coating is compromised?” Also, inquire whether they have experience working with silicone coatings and solar installations together. This approach helps protect your roof investment while allowing for clean and reliable solar panel installation.
