What is Standing Seam Metal Roofing?
Standing seam metal roofing panels are attached with concealed fasteners. Originally, clips engaged with the vertical legs and were used to attach the panel to the roofing substructure. As panel options have grown, however, it is common to see clipless panels included in this product family.
McElroy Metal offers five distinct standing seam systems that can be curved on the job site, lowering transportation costs and ensuring a proper fit.
Standing Seam Roofing Systems
Standing seam systems are used for a wide range of applications and projects. These systems feature interlocking seams that connect panels, giving the roof a distinct, and attractive, appearance. Furthermore, standing seam systems are manufactured from high-end steel or aluminum offering years of low-maintenance service life.
McElroy Metal standing seam systems are durable and weathertight, making them ideal for most any application.

Standing Seam Retrofit Systems
McElroy Metal is the industry leader when it comes to retrofit systems. McElroy’s retrofit offerings include flat-to-steep slope, Metal-over-Metal and Metal-over-Shingle solutions. We'll ensure you can find a cost-effective and viable metal retrofit system to fit individual needs.
Our retrofit system offerings include:
- 138T Shingle Recover – Can be installed directly over existing shingles and delivers energy-saving Above Sheathing Ventilation (ASV), making the system a terrific choice for both commercial and residential projects.
- 238T Metal-Over-Metal Recover – As the name implies, the existing roof panels remain in place for metal over metal recover systems. Skipping the tear off step not only saves building owners time and money but perhaps more importantly, their daily business operations aren't impacted. These systems feature a symmetrical 238T standing seam panel and are proven to last two to four times longer than single-ply recover.
- Low Slope to Steep Slope – We offer retrofit assemblies that are easy to erect and are a great way to convert worn out flat roofs into functional and highly attractive steep slope roofs.
Our retrofit systems offer customers and building owners viable and cost effective solutions for worn out existing roofs. McElroy Metal’s experience technical staff is available to help customize retrofit solutions, so give us a call. We are always happy to help develop creative and functional solutions with metal!
Advantages of Standing Seam Metal Roofing
Concealed Fasteners
Standing seam systems attach to the substructure with concealed fasteners. Since there are no exposed screws with washers than can shrink or crack over time, they are considered a more weather-tight system than exposed fastener systems.
Expansion/Contraction Ability
Standing seam systems allow expansion and contraction through either a clip or slotted flange. Conversely, exposed fastener systems are pinned which can result in the fastener hole elongating over time and allowing water penetration. Check this out to learn more.
On-Site Panel Production
Some manufacturers (McElroy Metal included) can produce standing seam panels on-site in lengths up to 250’. Single-piece panels are quicker to install, more weathertight and require fewer components making them a superior and often more economical system.
Aesthetics
Standing seam panels typically offer a distinct vertical leg. This tall vertical leg can offer a nice shadow effect and the illusion of a flat pan in between the major ribs which many architects and building owners prefer.
Extensive Testing
In order to meet stringent building codes and life safety issues, standing seam panels are subjected to more testing than exposed fastened type systems. Standard tests include uplift, air and water, impact, and fire resistance.
Weather Tightness Warranties
While additional charges and criteria typically apply, standing seam systems can often offer Weather Tightness Warranties where exposed fastener panel systems cannot.
