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.
This is why, if you’ve already got your roofing materials, that trying to do a DIY standing-seam roof installation is going to be so much more trouble than it’s really worth. If this sounds like a load of codswallop to you, and you intend to forge on no matter what the challenges, then here’s a couple of metal roof installation tips. First off, after everything’s been covered with a protective plastic membrane to prevent unexpected water seepage from entering the house, you should put down some roofing paper. Scratch that - lots of roofing paper. In fact, it needs to fill just about every bit of roofscape you can find, including the roof valleys (these are the spaces in between roof surfaces, which often resemble gutters). On top of that you’ll need to lay a ridge cap, a preformed cover that fits over the roof’s peak. The edges of this will be covered by your shingle, but it rounded apex will still peak out from the shingles, giving the roof it its essential character.
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.
When it comes to shingles, there are a few companies, such as Permanent Roofing Systems, that design shingles specifically made for DIY metal roof installation. There are four-way systems of shingles that can be made to interlock with each other by hand or with minimal use of tools. Get someone from the manufacturer, or a qualified person at your local construction outlet, to show you how to fit the pieces together, which should be in a staggered pattern for the best visual effect. The same company circulates a PDF choc-full of useful DIY metal roof installation tips available for download at www.permanentroofing.com. It’s possible to buy their shingles pre-assembled in sheets, making for the easiest possible solution to your roofing needs.
Should you attempt to do the job yourself, the most likely result will be a standing seam roof that either looks slapped together or else is easily damaged by leaking or swelling ice caught between panels. This is when the cost of DIY standing-seam roof installation can actually outstrip that of professionals - because you’ll probably need to redo the entire job at some point.
So maybe, on just this one occasion, it’s the time to loosen those fists and hand over the cash for a skilled roofer’s work. Indeed, if your worker as recommended by the manufacturer, or at least is recognized as qualified to install standing seam roof panels, it’ll mean that your roof is subject to warranty - and that you can look forward to fifty or more years of being secure in the knowledge that you’ve a strong roof over your head.
