Fast residential installs

1.5" Snap Lock

Panels snap together over clips, so most residential roofs can be installed without a mechanical seamer.

Best for
Homes and steep-slope projects where speed and clean lines matter.
Consider
Choose mechanical lock for very low-slope or more demanding assemblies.

More weather-tight seams

1.5" Mechanical Lock

Field-seamed panels create a stronger concealed-fastener roof assembly for tougher conditions.

Best for
Projects that need a stronger seam than snap lock but do not require a taller profile.
Consider
Requires seaming tools and more installation labor.

Low-slope and commercial

2" Mechanical Lock

The taller mechanically seamed profile is built for low-slope, high-wind, and heavy-duty roof assemblies.

Best for
Commercial work, lower slopes, and projects that need the most robust seam.
Consider
Usually more specialized to install than snap lock or nail strip systems.

Simple fastening layout

1.5" Nail Strip

An integrated fastening flange helps keep installation straightforward on simpler roof layouts.

Best for
Straightforward roofs where a clip-free concealed-fastener panel is preferred.
Consider
Less flexible for thermal movement than clip-fastened systems.
