FLASHLOC DUO offers a versatile solution for attaching to both composition shingle and rolled roofs, directly connecting to the deck and rafter. Its design eliminates the need to kneel on potentially hot roofs, bypassing tasks like installing flashing, manipulating shingles, or extracting nails. Installation is straightforward: anchor the mount using screws and apply sealant to the base. The FLASHLOC incorporates the innovative TRIPLE SEAL technology, ensuring the roof's longevity while establishing a steadfast, pressure-resistant seal around the penetration. Each kit comes complete with two rafter screws, sealant, and necessary hardware for ease of use (note: deck screws are not included). With FLASHLOC, it's more than just redirecting water—it's about effectively sealing it out.
