How to Install a Standing Seam Metal Roof from Start to Finish

There is no material more capable of protecting a structure from wind, rain, hail, fire, insects, or rot than a standing seam metal roof. One of the great advantages of standing seam roofs in particular, is that the seams, the weakest point in any roof and a potential entry point for moisture, are raised above the level of the roofing panel. Additionally, because the metal panels run unhindered from the top to the bottom of the roof, not only are there no horizontal seams but in total the roof has a far fewer number of seams than other roofing systems.

Cost Of Snap Lock Vs Mechanical Lock Metal Panels

The difference between snap lock and mechanical lock panels lies in how the individual panels connect to each other

Snap lock panels have fasteners directly attached to them. The panel itself and the fastener are all one piece. Panels simply snap together without any seaming or specialized tools. Snap lock panels are only an option for roofs with a pitch of 3:12 and up.

Cost of snap lock panels: The panels themselves might cost more than mechanical lock panels, but youll spend less on labor costs because snap lock panels are so much easier and quicker to install.

Mechanical lock panels, aka field-locked panels, take more work and expertise to install. Pros have to use a specialized tool to crimp and seal the edges of panels together. There are single-locked and double-locked versions. Both tend to withstand high-speed winds better than snap lock panels.

Cost of mechanical lock panels: Double-locked panels take longer to install, so they will cost you more than single-locked options. For either, expect higher labor costs and lower material costs than with snap lock panels.

    Whats The Difference Between Each Type Of Standing Seam Panel

    How to Install Snaplock Standing Seam Metal Roofing Panels on a House

    Each Standing Seam panel is installed and secured to the roofs substrate differently. Their names each reflect the different ways they come together.

    Mechanical Lock panels are mechanically fastened to one another, meaning a special tool called a seamer is needed to lock them together. These panels use a clipped system that fastens them to the substrate. Then, you use an electric or hand seamer to press them together mechanically, which bends each panel over one another and creates a lip. Mechanical Lock panels require a more advanced installation.

    Mechanical Lock

    Tru Snap metal panels have two identical female legs and snap together. With Tru Snap, the male leg is clipped, and that clip is fastened directly to the decking. These panels require more parts and pieces, making installation a bit more difficult. However, Tru Snap can be run with longer panels due to the clipped system it uses, which allows the panels to move more freely through expansion and contraction.

    Tru Snap

    Nail Strip metal panels also have two identical female legs. The big difference is that with Nail Strip panels, the male leg has a perforated nail flange used to fasten the panel directly to the decking. Nail Strip is a bit easier and more straightforward when it comes to installation, however it is limited by how long you can run the panels since theyre screwed directly to the decking.

    The success of the standing seam roof rests on the height and integrity of the seam. It typically projects 1 or more above the surface and is therefore higher than any running water.

    Among the most common roofs on old houses, standing seam metal roofs have been used with almost every architectural style since the basic materials became widely available in the mid-19th century. An ingenious system of metal sheets crimped together in seams that jut an inch or more above the surface, standing seam roofs are attractive and highly durable as the primary roof and one of the few options for low-pitched, secondary roofs over porches and bay windows.

    They are also relatively easy to install, especially on houses with a minimum of ridges and valleys, requiring only a few specialized hand tools and the average mechanical skills of an old-house restorer. If you are smitten by the appeal of metal roofs, here are the basics to get you started on your own.
