"My home was built in 2004 with an asphalt roof. The area was always subjected to high winds and pieces of my asphalt roof were always breaking off after a few years. I live in a two story single home and frankly was getting tired and old of having to go on my roof and repair shingle panels. I looked at both asphalt and metal choices. The quotes on the asphalt would guarantee the product 25 years. This always sounds good but it would not guarantee minor shingle damage do to wind and weather. I started to investigate metal roofs and although I knew they were more expensive I also knew that it would last my lifetime and beyond. I did extensive research and made a lot of conclusions. My first piece of advice is DON'T go to your local Home Improvement store and seek out local contractors in your area that say they can do a metal roof installation but in reality never did one. There is a certain skill set involved. Secondly look at the quality of the product itself. In my case I wanted the thickest gauge and I wanted what was referred to as Standing Seam. I did not want exposed fasteners with rubber grommets that crack and could break loose in time. The company "Custom Construction Systems" gave me a honest quote which included a complete tear off and new underlayment installed. I definitely wanted that. Some of my neighbors that had lower end metal roofs installed it directly over their old asphalt roof. The product I got was true 24 gauge which is often used in industrial settings. Some of the products at the Home Improvement stores would actually add the paint thickness with the metal thickness. Keep this in mind! The advantages of metal over asphalt are hands down better. If you are environmentally concerned, metal roofing is 98% recyclable and is probably already being used from recycled metal. I was able to see homes and businesses that were done and the company and workers were very professional. My roof turned out beautiful. It was very affordable too for a high quality product and a team of workers that knew how to do metal roof installations. "Custom Construction Systems" also delt directly with the manufacturer of the product. This was a huge advantage in the cost of the project. If you do your own investigating like me you will soon find out that the manufacturers product cost is highly inflated by the distributer. Thanks for reading and good luck."
