Standing-seams roofs are made up of many shingles or panels that interlock on the vertical axis, running from the roof's edge to its eaves. The point where two panels interlock (the seam) is raised a little off the flat roof surface, which allows water to run off the roof without any seeping between panels. Based on seemingly simple structural principles, the complexities of installing a standing-seam roof are not to be underestimated, the reason that DIY standing-seam roof installation will seem like a risky proposition to anyone in the know.

And indeed, while getting hold of the roof components might be a bit expensive, the installation is the exact opposite. Indeed, metal roofing panels of the standing seam variety are very light - often no more than a pound - and as such your contractor's not going to charge you anything near the rates he would installing heavy traditional materials. If he does, well, he's trying to stiff you, and you need to shop around for a new contractor. When you don't even need to remove the old roofing materials to install a new layer, there can be no cause for amplified up costs beyond the belief that you're dealing with affluent, gullible customers.

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.

If you're intent on going through with your DIY standing-seam roof installation, however, here's a few tips. You'll probably want to lay down some kind of waterproof plastic membrane over the existing roof structure, followed by a good layer of roofing paper which will ensure that water stands no chance of making it through and into your home. Don't neglect to fill in the roof's valleys (the spaces between roof surfaces). Then you'll need to cover the roof's peak with a preformed ridge-cap, which you'll need to get made to order unless you really intend to go into the roofing business professionally.

Now, all this is well and good until you realize that your roof isn't regularly shaped. And I'll tell you, most peoples' roofs fall into the category of irregular. Just about everyone's roof has some kinky little feature, like a skylight or a chimney or a dormer, that needs to have pre-made shingles cut in accordance with its shape. Should you attempt to use your regular shingles without consideration for the unique requirements of these areas, you're going to end up with a roof that is either ugly or practically ineffectual. The fact is, the tool for this job is not a saw or a hammer, it's a hydraulic powered shear with teeth sharper than razor blades that trained professionals use to quickly cut standing seam roofing panels to size on site. It's called a brake, and it's the reason you want a pro doing this kind of a job.

That said, there are going to be certain circumstances under which pre-made shingles just won't be enough, and that's when you need to swallow your pride and call in the pros. On roofs with irregularities - things like sidewalls, chimneys, dormers and skylights - standing seam panels will need to be cut to size on-site, which requires the use of a sophisticated piece of machinery called a brake - a hydraulic shear with teeth sharp enough to cut panels to just the right length without damaging their ends. That's one feat it's very difficult for a human saw-wielder to replicate.

If under such circumstances you persist in your DIY efforts, the odds are that patch jobs around irregular areas are either going to look bad or result in your standing-seam roof being compromised, leading to leaking and other forms of weather damage, such as the negative effects that swelling ice can cause when caught between panels. Properly installed standing-seam roofs are subject to warranties of up to fifty years, given the nigh-on invulnerable hardiness of the materials. So don't skimp now - a once-off investment could leave you with a roof that lasts a lifetime.
