When hearing the term “metal roofing,” most people think of commercial or industrial buildings, such as warehouses and factories. However, metal roofs are becoming increasingly popular for residences due to this material’s durability, protective qualities, and longevity.
Various types of metal roofing are available, including metal shakes, tiles, and slate-inspired shingles. Standing seam metal roofing is one of these options we often recommend, thanks to the wide range of advantages it offers.
In this blog post, we take a closer look at the standing seam metal roof. If you find it appealing, contact us today to find out if this roof type might be a viable option for your home.

What Are Standing Seam Metal Roofing Systems?
A standing seam metal roof is a metal sheet system consisting of flat panels between raised seams, legs running vertically across the roof slope. These raised seams typically serve as the connection point between sections.
Concealed fasteners are one of the main characteristics of standing seam metal roofing. Depending on the standing seam profile, metal caps or edge folds cover the seams between two panels or the fasteners between a panel and the roof deck. Some standing seam profiles use a snap-lock system or tee-seam cap as a locking mechanism between panels.
Standing Seam Systems: Profile Types
The profile type of a standing seam metal roof refers to the connection mechanism between two panels. The standing profile type that your roof needs depend on the roof deck structure, the roof slope, and various architectural factors.
A snap-lock panel has roll-formed edges that can snap together to form one waterproof and rigid roof system. This panel has a male edge on one side and a corresponding female edge on the other. A clip serves as the panel’s attachment to the roofing deck.
The snap-lock panel profile is only suitable for roofs with a slope of 3/12 or higher, and it is one of the most cost-effective standing seam roofing options.
Mechanical Lock Panel
Panels with a mechanical lock profile have roll-formed edges that correspond with each other. The difference between a mechanical lock panel and a snap-lock panel is that the former involves using a seamer to bend the edges, forming a tight, waterproof seam.
The two types of mechanical lock profiles are:
- Single-lock, or 90-degree seams
- Double-lock, or 180-degree seams
Single-lock mechanical panels are easier to install than double-clock systems. However, double-lock systems involving two seam folds perform better in cold weather.
Forming a batten seam involves butting the adjoining edges of two panels up and covering the seam with a metal cap. This panel system is common in Europe and keeps the roof resistant to high winds. Installing this panel profile is a relatively quick process and doesn’t require specialty tools.
The nail flange profile has a similar panel seam mechanism as the snap-lock panel. However, instead of a deck-fastening clip, a fastener through the panel’s male leg secures the panel to the roof deck. The female leg that snaps over the male leg conceals the fastener.
The Advantages of a Standing Seam Metal Roof
Why should you consider installing a standing seam metal roof?
- The fasteners are unexposed, mitigating the risk of corrosion, leaks, and UV damage.
- The metal panels accommodate thermal movements, making these roofs silent and not prone to cracking.
- The durable standing seam metal panels have a long functional life expectancy.
- The metal panels have a modern appearance, and you can choose from various panel sizes, profiles, and colors.
- The standing seam metal roofing options allow for architectural flexibility, and they are visually compatible with most residential design styles.
