OK, here is my question, hope you can help... I am redoing a 100 year old porch roof and have taken off the old crimped tin. The new metal roof looks like below.. ____________^^^__________^^^____________ etc. My problem comes in here. Where two sides meet as the porch curves around it looks kind of like where two sides of a very flat pyramid meet and I am wondering how to seal/butt/crimp the seam where they meet? The old crimp style roofing just had the ends turned up and it was a straight crimp down the seam, but with the design of the new metal, this does not seem possible. I have a porch that is stripped clean of old tin and ready to be re-roofed as I write, and am perplexed about how to solve this problem. Thanks in advance for any help. Matt

Ok, I guess it is called a hip joint (newbie to roof terms). I read something about some sealer tape? or caulking? but it seems like it will take a lot to seal the area where the cap doesnt touch the metal roof in the low flat areas. I am sure that there is some easy answer, but I haven't done any metal roofing before. Thanks. Matt

It is called a hip. You need a 5V Crimp Hip base Flashing and also then a hip cover. The base flashing must be installed prior to the adjacent roof panels. Yes, butyl tape will be used as well. Please do not proceed with your installation without first having complete installation instructions from the roofing manufacturer. If such instructions are not available, then you're not working with a manufacturer who cares about installation. They might also not care about making a quality product. Find another manufacturer -- please -- or else you might be later writing in here with a roof that is not performing as you expected it to. Thanks so much for choosing metal.

Thanks for the advice. I purchased it from Lowes special order so I am not sure of the manufacturer. Would you have any idea who supplies Lowes with their metal roofing? Thanks. Matt

I suspect that they have several suppliers. However, there is a chance that this material is from Union Corrugating. Union is not a member of the Metal Roofing Alliance.
