Fasteners Exposed
Exposed fasteners are typically used with the “post rib” profile panel. Which is a 29 gauge panel, 36″ wide with ribs every 9 inches. NOTE: There are other profile options available. This is your cheapest roofing option available using metal. This panel gets fastened with a screw line every two feet, screw spacing of nine inches. It makes a nice-looking roof but does require some maintenance.
Fasteners Concealed
Standing seam profiles offer a fastening system that allows every single screw to be concealed. There are a number of different profiles available. The most common residential profile is the 1″ snap lock. Which is a 26 gauge, 16″ panel with a 1″rib on each side. The pictures on this website are of this profile. This roof requires no maintenance. It has an incredibly clean and crisp look.

Slotted Screw Hole for Montana Metal Roofs
The difference with the standing seam is the screws are installed in a slotted screw hole. That allows the metal to expand and contract without working the screws. This roof will last for 50 years with no maintenance whatsoever.

Expand and Contract
The temperature fluctuation we get here in Montana causes the metal to expand and contract. When using the exposed fasteners that really works the screws and with time they will start backing out. When that happens you have a tiny leak by each screw and eventually it will compromise your whole roof. The important thing is to tighten the screws every five years or so.

Difference in Thickness
Both the exposed and concealed fastener systems have the same paint and carry the same manufacturer warranty. There is a difference in thickness. The standing seam is 26 gauge and the post rib panel is 29 gauge. The standing seam is to some degree a more rigid product. Both are equally rust-resistant and carries the same 50-year paint. The most significant difference is the fastening system.

Common Questions
Metal roofs are durable, energy-efficient, and low-maintenance. However, there are common concerns such as weight, noise, types of metals, longevity, cost, maintenance, installation techniques, and sustainability.
The cost of a metal roof depends on the roofing system you choose. Our post rib roofing can be similar in cost to shingles, while standing seam roofing typically costs more upfront. Metal roofing is designed for long-term performance, so it can be worth comparing the initial cost with expected maintenance, durability, and how long you plan to stay in the home.
Yes. Our standing seam and post rib roofing systems use the same paint system and carry the same manufacturer warranty. The roofing products currently listed on our site include a 50-year paint warranty. We can review the warranty details for the specific roofing system and color you choose.
We offer different gauges based on the roofing system. Our residential standing seam roofing uses 26-gauge steel, while our post rib exposed-fastener roofing uses 29-gauge steel. The standing seam panel is thicker and uses concealed fasteners for a clean finished appearance.
Exposed-fastener roofing uses visible screws that attach directly through the panels, while standing seam roofing hides the fasteners beneath the panel system. Exposed-fastener roofs may need more periodic maintenance around the screws. Standing seam roofing provides a cleaner look and allows the metal to expand and contract with less stress on the fasteners.
Yes. Snow generally slides off a metal roof more easily than it does from many other roofing materials. Snow may build up for a time, especially in valleys or shaded areas, but the smooth metal surface can help it release as temperatures warm or the roof gets direct sunlight.
