62611 WeatherMaster Metal Roof Advanced Polymer Sealant, Silver

Product works great on sealing electrical j-boxes on a canopy roof. Seals dirty metal as long as it is not wet. Seals drill screws through the canopy by inserting the end of the caulking tube over the screws and adding a dab of caulk. Looks like a gray Hershey Kiss on top of the screws and easily seals to the aluminum decking. Great elastomeric sealant for aluminum & steel decking, screws, & gutters. Went through 20 tubes on one large job alone- and worked fantastically. No leaks after a week-long heavy rain!

Titebond WeatherMaster lives up to its name. I’ve used this sealant on multiple standing seam metal roofing jobs, and it performs exceptionally well. It adheres strongly to coated and uncoated metal, aluminum, steel, and even synthetic underlayments with zero issues. It skins over quickly, but you still have enough working time to tool it cleanly. Once cured, it remains flexible and completely weatherproof—even under full sun, heavy rain, and sub-zero temps. No shrinking, no cracking, no chalking. It also matches most standard gray metal roof trims nicely. Pros: Sticks to just about anything Paintable and low odor Remains flexible, won’t dry out or shrink Excellent color match for gray flashing and panels Whether you're sealing seams, fastener heads, or flashing details, this is a contractor-grade product that won't let you down. Highly recommended for pro use or demanding DIYers.
