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.

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.

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.

Welcome to part two of our three-part series on 3 Tips for Mounting Anything to Your Exposed-Fastened Metal Roof. Our goal is to help you preserve your metal roof’s service life as you attach solar panels, snow guards, HVAC equipment or other accessories.
We hope you gained some new insights from our first blog in this series on the importance of materials compatibility.
In the near future, we’ll round out these valuable tips with an explanation of how load testing the brackets of your rooftop-mounted ancillaries is key to protecting your exposed-fastened (EF) metal roof.
Today, we are taking a deep dive into another vital topic to preserve your roof’s integrity: the world of proper sealants.

Part One -
Are you mounting solar panels, snow guards, HVAC equipment or other accessories to your exposed-fastened (EF) metal roof?
If so, we’ve put together a three-part series on our top tips for successful installation to preserve your roof’s service life.
Over the course of the next three blog installments, we’ll cover:
- The importance of materials’ compatibility between the mounting attachments and your metal roof.
- The right time and place for you to use EPDM and butyl sealants.
- Why load testing is key to protecting your metal roof.

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.

Micro rails are a relatively common way of attaching a solar array to exposed-fastened metal roofs. This method uses small rail sections in specific areas as needed along the roof – reducing the total length of rails. They have benefits which make them desirable to contractors and installers alike. They provide material and shipping cost savings to the customer when compared to rail systems. In addition, they are small, which allows them to be handled easily onto roofs. They are forgiving with spacing allowing for minimal or customizable walk spaces. Additionally, micro rails can be installed with just a couple of fasteners - potentially cutting installation times compared to rails.

Massive snow accumulation on a roof creates the potential for an unpredictable avalanche-like effect. Metal is a great choice for your rooftop. It has a long life expectancy and can stand up to the harshest conditions. It does have a low coefficient of friction though–meaning things (including snow) don’t stick to it very well. But the notion that snow is intended to slide off a metal roof is misguided and can be dangerous.
