How to Repair a Leaking Seam?

Return to I Have An Existing Metal Roof and Have A Question

Return to Forum

I have a seam across the metal vertical panel roof on the house I just purchased that leaks. During heavy rains, water backs up into the seam and drips out the ceiling in our sunroom below. The seam is from an addition installed a few years after the main house was constructed. Should I raise some metal roof panels, determine if the sheathing underneath is rotted and then reseal the seam the correct way? What would be the proper method and materials to use to seal the seam properly? I've attached some photos. These is also a messed up valley and vertical roof intersection that looks sketchy. Thanks for any advice. Rick

At least it is an exposed fastened system in this case and it can be uninstalled and reinstalled. Can't tell much that is wrong with it from that picture. I am guess they got the lap and that valley incorrect. That is clearly not the first layer of sealant so all that needs to get cleaned off and pulled up anyway. Do you have a contractor in mind?

I'd like to do it myself. I've reroofed my other houses with the traditional asphalt / fiberglass shingles, felt, sheathing and ice barrier products. This is my first experience with a metal roof and am not familiar with how a proper seam / joining of existing and newer addition roof should be worked for a leak-free seam. Thanks for any advice on forming a new seam! Rick
