Standing seam metal roofs are popular among home and building owners in hot climates or places where wind resistance is essential.

There are two types of these roofing systems in production today: snap lock standing seam and mechanical seam systems.

While there are many instances when standing seam metal roofers find snap lock systems superior to the alternative, there are also some downsides to choosing these systems.

Home and building owners can make an informed decision by understanding more about popular snap lock metal panels, how they work, and whether they are suitable in their location based on local climate conditions.

What Is Snap Lock Standing Seam Metal Roofing?

A snap lock standing seam roof is one made from metal panels designed with a snap-together fastener system.

These panels go together more quickly and easily than mechanical seam panels, which require manual crimping.

Constructed with male and female interlocking seams that clip snugly together, snap lock standing seam roofing is affixed to the roof with fasteners that are installed beneath the panels so they are not visible and remain completely protected.

When appropriately installed by a professional metal roofer experienced with snap lock systems, they make an attractive and durable lifetime roof.

What Benefits Do Snap Lock Standing Seam Metal Roofs Provide?

Snap lock standing seam roofing is a favorite metal roofing system due to the significant advantages it offers those looking for the beauty and protection of a tough metal roof:

Faster Installation - Snap lock standing seam roofs can be installed much more quickly than mechanical seam systems, as they snap securely together without crimping or having to use any additional tools other than those needed to install the fasteners.
A More Affordable Standing Seam Roof - Since snap lock systems involve a faster, and less complicated installation process, they are less expensive than mechanical seam systems which require every panel seam to be crimped.

Are There Any Drawbacks To Snap Lock Standing Seam Roofing?

As quick and affordable as a snap lock installation can be, metal roofers highlight that it is not suitable for every home or building based on a few important limiting factors:

May Not Be As Weather-Resistant - Since the seams are snapped together and not crimped together, they are not as watertight in heavy rains nor are they as resistant against strong wind uplifts. To improve wind resistance, snap lock panels in shorter widths may be a suitable solution.
Minimum Pitch Requirements - Based on their reduced ability to stay watertight, snap lock standing seam roofing should only be used on buildings with a pitch of 3:12 or steeper to prevent leaks.

Discuss Metal Panel Choice With Experienced Metal Roofers

Snap lock standing seam metal roofs are a desirable standing seam option for homeowners who seek the benefits of metal roofing with the greater affordability of a faster, less complicated installation.

Yet professional standing seam metal roofers may not recommend them for all structures based on details like roof pitch, local rainfall, wind speeds, and other factors.
