Corrugated Metal Roof vs. Standing Seam

Could you please elaborate on the pros and cons of corrugated metal roofing that one can purchase at a hardware store or lumberyard and have installed by any skilled carpenter, and the standing seam and ?"seamless" products available. We live in Maine and have a 45 degree pitch on our residence. We are concerned mostly about durability and longevity, and less about appearance. We also want to avoid ice dams as much as possible. Also, I have recently read that a TV antenna should extend 10 feet above a "flat" metal roof; does this apply to one with a 45 degree pitch as well? Will the metal roof interfere with TV reception? We live in a rural area and rely completely on a large antenna for our reception. Thank you for your time and consideration. Jon Bailly

The comparison of various vertical seam roofs is amazingly complex and, ultimately, I suggest gathering as much information as you can about the products you're considering by actually talking to their manufacturers. When choosing a metal roof, paint finish is a big factor. Be certain that you're comfortable with the finish on the product you choose -- check out its durability and warranty. The corrugated "sheet" style of roofs typically have not only horizontal seams but also exposed "through" fasteners. Standing seam products typically have no horizontal seams, as well as concealed fasteners and fasteners which go through clips rather than the panels themselves, in order to allow for expansion and contraction of the metal. I have never heard of complaints regarding television recption except when the antenna was actually in the attic. All best.

Are stand and seam more reliable? It seems that screwing to your roof with the corrugated is just giving water a path into your house. Please inform me. The best you can.

I suppose some folks may take me to task on this but I believe it is safe to say that standing seam systems with hidden fasteners and allowance for the metal's thermal expansion have more reliable track records than do through-fastened products.
