5 Reasons Rail-less Is the Future of Metal Rooftop Solar Mounting

Posted by Kelli Fields on Jul 21, 2021 11:48:21 AM

When it comes to attaching solar modules to metal rooftops, traditional rails have been a conventional choice. But familiar concepts don’t necessarily deliver the best outcomes, and the advantages of rail-less solutions are moving the industry in a new direction.

Decades ago – when interest in mounting solar PV on rooftops began – the introduction of using continuous aluminum rails as a solar racking system to mount PV modules in place was a practical application for all roof types. Eventually, innovation opened new doors and rail-less solutions were developed specifically for metal roofing. Using discrete hardware to directly secure each module to a metal roof, the new strategy completely bypassed the need for rails and brought some clear improvements.

Today, we’re breaking down the top rail-less benefits leading to a growth in popularity and positioning rail-less to be the new metal rooftop solar mounting standard for the future.

Rail vs. Rail-less: Which Is the Best Solar Mounting Platform for Your Roof?

Posted by Kelli Fields on Jul 7, 2021 1:30:38 PM

If you’re thinking of putting solar PV on your metal roof to generate renewable energy and save money over time, you’ve made a great choice. Metal roofs are an ideal platform for mounting solar modules thanks to their long service life and durability. Solar arrays have a service life of 35+ years, and metal roofing has a demonstrated service life of 60 years. Aside from metal, there are no other roof types that measure up to that without requiring replacement. Both standing seam and exposed-fastened metal roofs support solar arrays very effectively.

Part Three -

Your exposed-fastened (EF) metal roof offers a great opportunity to mount solar panels, snow guards, HVAC equipment or other accessories. But you need to protect your roof’s service life and the performance of whatever you’re installing. To help you make the best decisions upfront, we’ve created a series on 3 Tips for Mounting Anything to Your Exposed-Fastened Metal Roof.

In earlier posts of this three-part series, we covered:

Can You Mount to a Standing Seam Metal Roof Without Voiding the Warranty?

Posted by Kimberly Reichert on May 8, 2020 10:40:43 AM

Non-penetrating rooftop mounting refers to the ability to mechanically attach a clamp to a standing seam roof by gripping the seam in such a way that there is no penetration to the panel material. The best method for standing seam clamp attachment is via round-point setscrews.

How to Install Solar Panels on a Metal Roof: 5 Things to Consider

Posted by Kimberly Reichert on Nov 15, 2019 8:54:50 PM

Did you know that your roof already comes with free rails? You can mount PV directly to the roof panels themselves - using the “direct-attach” method. Whether you are dealing with standing seam or ribbed, face-fastened panels, these metal roofs have one thing in common: They all have built-in rails.

What is the Difference Between Metal Roofs and Asphalt Shingles?

Posted by Kimberly Reichert on Mar 18, 2019 11:59:16 AM

Pop quiz. Should you install a metal roof or asphalt shingles? Which is a better choice? Asphalt shingle roofs are everywhere. But metal roofs have been in use for almost three thousand years. They have come a long way from the simple, yet functional corrugated or standing seam metal roof design usually associated with barns or sheds. So, which is the best choice for you? To answer this, let’s take a deeper look under the hood, or the roof, as it may be.

Top 5 Reasons for Installing Snow Guards on Your Metal Roof

Posted by Kimberly Reichert on Feb 25, 2019 2:17:15 PM

Have you been carefully (or not so carefully) monitoring that gravity-defying overhang of migrating snow that sits atop your roof? Glistening beautifully in the sun, it has stayed up there for days; it will surely stay up a bit longer, right? Sorry, no guarantee. Avalanches are unpredictable and catastrophic events. The snow will fall wherever and whenever it wants to – on you, a loved one, your car or sidewalk.

What is the Best Way to Mount Solar on Exposed-Fastener Metal Roofs?

Posted by Rob Haddock on Mar 8, 2018 1:48:02 PM


Upon reading the Solar Power World article Metal Roofs are No Problem for Solar Installations, my reaction was, "Well, I suppose that is true—if (and only if) it is done 'the right way.'" There are so many materials, profiles, gauges, metallurgies and corrosion behaviors to consider; not to mention effective waterproofing methods, sealant chemistries, thermal cycling characteristics, weathering behaviors, strength of materials, structural engineering principals and relevant test methods. It is anything but a simple science!
