Titebond 62611A WeatherMaster Metal Roof Advanced Polymer Sealant, Silver

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 anythingPaintable and low odorRemains flexible, won’t dry out or shrinkExcellent color match for gray flashing and panelsWhether 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.

Very very sticky. Not silicone based. You can't smooth it once it's applied. That was okay with me since I was using it outdoors. Seems to be very strong once dried. I"m happy.

Great sealant

Works really good color is as advertised seems to be holding great time will tell!

used on gutter ends

Just what we needed for sealing on a metal roof.

My husband has me order this brand from Amazon, even though he could buy other brand around home. He calls it the "Good one"

This was recommended to me by a roofer, and I am so happy with the result. It perfectly sealed the cracks in my roof, going from failed hose test, to passed in no time.
