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.

A Slotted Screw Hole
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.
Yes, much better. Generally the snow will build up a couple inches then slide off. Even in valleys where it builds up a bit, once it gets some sunshine it will soon work its way off the roof.
The post rib panel is very similar in cost to shingles. The standing seam is more expensive. While none of us have money to through away it is worth considering the investment you are making in a metal roof. Especially the standing seam. Shingles typically last 20 years where a good metal roof should last double that. Also a metal roof will add value to your home.
It will fade some. The paint companies have really improved the quality of their paint in the last 10 years. There is a lot less fading now then there was. For the first 20 years you should not be able to tell that it has faded.
