If you're seriously considering a DIY standing-seam roof installation, you'd best bone up on your general knowledge regarding what is undoubtedly a great roofing solution. While successful amateur installations are not unheard of, your surest bet is to seek the help of a professional. Standing-seam roofs are made of numerous interlocking panels, which run vertically from the ridge, or edge, of the roof to its apex at the eave. The seam where any two panels interlock is raised just above the surface of the roof, allowing water to run off the roof without it dripping in between the panels. This simple structure belies numerous details of installation that, if not properly attended to, can lessen the efficacy and lifespan of the roof.

Also, should you choose to hire a professional accomplished in the craft of roofing, you're probably not going to find yourself looking at roof installation costs that are anywhere near as expensive as those of ordinary clay or fiber-glass shingle installation. Metal roofs in general and standing-seam roofs in particular are lightweight (between 1 and 2 pounds apiece), making them very easy to move around. They can also be installed over the old roof, which eliminates the time and manpower it might have required to tear the whole previous layer of roof off.

Properly installed, standing seam roofs are watertight, immune to the forces of wind and hail, fire retardant and require virtually zero maintenance aside from the odd hose-down every year or so. Indeed, they so improve the safety of your home that many insurance companies are willing to cut large amounts of money off the cost of their policies for homes with metal roofs.

Now that that's all done, you're ready to start worrying about the shingles, or roof paneling. Ask around at the construction outlet or hardware store where you first procured your shingles and find someone that can demonstrate the manner in which the shingles need to be fitted together. If you haven't bought the materials yet, you should know that there are a bunch of companies that make panel solutions that are really easy to clip into place, designed for DIY standing-seam roof installation and requiring nothing but your hands and perhaps the most rudimentary assortment of tools.
