Burst Seams on Tin Roof

I have a wrap-around porch on my house with a tin roof that has soldered flat seams. The seams in several places have split open, causing leaks. I am looking for a way to repair those seams without having to have them re-soldered. Some web research has suggested fiber mesh and Liquid Roof, but how will that RV product look on a house roof? I have the roof painted black so it might not be very noticeable. Any advice?
