Titebond WeatherMaster Metal Roof Sealant 62431 Gray 9.5 Oz.

I purchased & used this Excellent leakproof Caulk on my 5 year old Metal Roofs. Exactly Same Caulking Roofing Contractor Used . So, after installation one year later, and then Once a year afterwards as to Inspect and re-seal( if necessary.)For all vents, seams, chimney flashing ,etc keeps my roof in good shape on both Buildings. One is a 2000 'sq. Hangar. & House is 3600'sq. Ordered 6 Tubes & Used only 4 Tubes with a bit left over in the last tube. I always keep a few tubes on hand living in South Florida. This product is a tough as they come and holds up very well. Preventative maint is the key which keeps us Happy and dry.

So I have older 24x48-ft building tin roof so it seals well helping prevent leaks. It's pretty sticky. I just went with a gray to match the tin roof. Seems to be pretty durable as we've been getting a lot of rain here lately

Just finished a 30x40 agricultural building using used and sometimes pitted metal roof. Sealed pin holes and seam leaks easily. Dries quickly and can be applied in any temperature above zero

So I used this to seal several vents and pass-throughs on a metal shop (not technically a roof, but essentially same material) and it worked pretty well. The color seems a bit darker than what is shown on the listing, it's a pretty dark gray. It's also a little hard to control. It's not runny, but for caulking the consistency is pretty thin. It makes controlling it a little more challenging than standard caulking. Hopefully that means that it will flow into gaps a little better than it would otherwise and seal even better. I can't confirm if that's the case or not though. It does have a screw on nozzle which I think is nice, but I can see why others might not be a fan of it. Overall though, nice product, works well for the intended use.

I used this on my shed when I put on a metal roof about a year ago. It is holding up well.

Just what my cargo trailer roof needed to reseal it against leaks. Couldn't find it easily locally so Amazon came through with quick delivery and reasonable price.
