FLASHLOC DUO offers a flexible solution for attaching to composition shingle and rolled roofs. Designed for direct attachment to the deck and rafter, it eliminates the complexities of flashing, prying, cutting shingles, or removing nails. Installation is straightforward: secure the mount using screws and apply sealant to the base. The FLASHLOC incorporates patented TRIPLE SEAL technology, ensuring a durable pressure seal around the penetration. Each set includes two rafter screws, sealant, and necessary hardware for ease of use (deck screws not included). With FLASHLOC, it's not just about redirecting water; it's about securely sealing it out!
