Top Unirac FAQs with Jim White
What is the difference between FlashLoc Comp and Duo?
Comp anchors into a rafter with one 4 inch stainless lag. Duo screws straight into the roof deck, six fasteners into standard sheathing, so placement is not tied to rafter lines.
Does FlashLoc really seal without flashing?
Yes. Triple Seal Technology combines a conforming gasket, a pressurized sealant chamber, and an injected sealant port for a waterproof connection, with no shingle lifting and no metal flashing.
How long is the Unirac warranty?
FlashLoc attachments carry Unirac's 25 year system warranty covering materials and workmanship, with 5 years on the finish. Install per the published guides to keep coverage intact.
