Premium Butyl Sealant for Solar Mounting Applications
AlphaSeal™, also known as RT-Butyl, is Roof Tech’s proprietary sealing tape designed specifically for waterproofing solar mounting bases like the Mini Base 2. This high-performance butyl tape is engineered to form a durable, weather-resistant barrier between the mounting base and roof surface—ensuring leak-free, flashing-free installations.
✅ Watertight Seal Without Metal FlashingAlphaSeal™ eliminates the need for traditional metal flashings by providing compression-sealing when used under mounting bases. Once fastened, it forms a long-lasting bond to roof surfaces and prevents water intrusion—even in extreme Canadian weather conditions.
✅ Installer-Friendly FormatSupplied in easy-to-cut rolls, AlphaSeal™ is quick to apply, clean, and efficient—saving labor time on-site while maintaining compliance with Roof Tech's tested installation methods.
✅ Ideal for Repairs, Extensions, or Custom LayoutsUse AlphaSeal™ as an add-on when additional material is needed for extended installations, repairs, or extra protection on complex roof layouts.
