Low slope porch roof

Can anyone provide some guidelines for deciding on metal roof for a low slope roof application. Pros and Cons kind of thing, or some guide that would help to decide whether the two porch roofs that will require roofing after renovation is appropriate. Have heard numerous opinions but no definitive answers.

If it is under 3:12 pitch I would suggest a mechanically seamed standing seam. Also, sometimes ventilation can be an issue on these roofs. I'd be happy to discuss your situation in detail. Please feel free to call me at 1-800-543-8938 ext 201

Mechanical seam panels can be applied as low as 1/4":12 with commercial height of the seam (1,5 or 2"). Its always the flashing details and also valley connection you need to take into biggest account on low slope roofs and roof to wall detail.... There is way to tie valley to all panels with double lock mechanical seam rather than Z flashing and butyl tape, or hook method. With proper design: valley can be dropped-recessed few inches to work as deep troft and the double lock mechanical seam can be lay down:) There is issue of condensation on underside of the panel resulting in pre mature rusting.... This is fairly new topic in US and drainage mats in combination with underlayment and proper ventilation should be taken into account. All tile products in general are most comfortable at 4:12 and greater. Some are ok at 3:12.
