Standing Seam vs. Exposed Fastener Metal Roofing: What Are You Actually Paying For?
FROM THE ROOF
Lessons from years of installing, repairing, and building metal roofing systems.
Every roof has a story.
Some stories are about craftsmanship that lasts for decades. Others are about expensive mistakes that could have been avoided.
After years of installing roofs across Montana, I've learned that the biggest decisions homeowners make aren't always the ones they think they're making.
From the Roof is a collection of lessons drawn from real projects, real repairs, and real conversations with homeowners—not marketing brochures or manufacturer talking points.
Just the lessons that come from years of working on roofs.
I'm Not So Easily Convinced
I didn't start out installing standing seam.
When I first got into roofing, I was installing shingles and 3-foot Tuff Rib. Standing seam came later.
I remember my first standing seam job. It was over in Seeley, and looking back on it now, I was completely clueless.
Epic Steel had recommended me for the project. We had to tear the shingles off first, and it wasn't exactly an easy roof to learn on. It was steep, with lots of dormers and pitches. The whole thing was pretty cut up.
I was a rookie.
And it wasn't a rookie job.
But it went really well. The homeowners were happy, and it gave me my first real experience with standing seam.
That didn't mean one job convinced me.
I'm not so easily convinced.
I like to see how something plays out over time.
The more standing seam I installed, the more I understood the system. Over the years, I got to see how those roofs performed.
That's what convinced me.
Today, if you ask me which metal roofing system I think is better for a home, I'm probably going to tell you standing seam.
But that doesn't mean everybody needs it.
So What Are You Paying More For?
Standing seam isn't the only metal roof that'll keep your house dry.
Exposed-fastener metal works. I've installed a lot of it.
The difference is what you're getting for the extra money.
With an exposed-fastener roof, you've got screws going through the face of the metal. Those screws have washers that seal around them, and over time, they can back out. That doesn't make it a bad roof. It just means you've got something you'll need to keep an eye on.
Standing seam is different. The fasteners are hidden, so you're not relying on exposed screws across the surface of the roof. It's also a heavier, higher-end system. It takes more labor to install, and you get a cleaner finished look.
You're usually looking at another $2.50–$4.00 per square foot for standing seam, depending on trim options. You're paying more, but you're getting something for that money.
I think about it a little like the difference between a rez runner and a GMC Denali.
They'll both get you down the road.
You don't need the Denali. And not everybody should buy one.
But if you've got the money and you care about the things you're getting for it, that's different.
Roofing is the same way.
If all you need is a good metal roof and you don't mind checking the screws once in a while, exposed-fastener metal may do exactly what you need it to do.
If you want hidden fasteners, less maintenance, a cleaner finished look, and a higher-end roofing system, that's where standing seam starts to make sense.
The question isn't just whether standing seam is better.
It's whether the things that make it better matter to you.
What Premium Installation Actually Looks Like
One of the things I like about standing seam is that the fasteners are hidden.
But that only works if you install it that way.
At the bottom of the roof, I don't want to see somebody run a screw through the face of the panel to hold it down. The rib should be cut back, the bottom of the panel hemmed, and that hem hooked onto the eave trim.
The same thing applies where panels run into a valley. Those panels should be hemmed too.
When you're installing trim, you can use Z-bars to fasten it without putting screws through the face of the roof.
Those may sound like small details, but they're part of what makes the system work the way it was designed to work.
The whole point is no exposed fasteners on top of that roof.
If somebody starts putting screws through the face of standing seam panels, you're taking one of the biggest advantages of standing seam and giving it away.
You don't need to know how to install standing seam yourself.
But if you're paying for a premium roofing system, you should know what that system is supposed to give you.
A Premium Way of Installing a Premium Product
Before I got into standing seam myself, there was a contractor out of Stevensville I watched on a couple of projects up on Flathead Lake.
He did really good work.
One thing I noticed was how much attention he paid to laying out the panels before he started installing them.
Say you measure across a roof and figure out that if you start with a full panel on one end, you're going to finish with half a panel on the other.
You can do that. The roof will still work.
But that's not how he did it.
He'd lay out the whole roof so the panels were balanced. If the measurements meant he needed a partial panel, he'd work that into both ends instead of leaving one odd-sized panel at the end.
Most homeowners probably wouldn't know why one roof looked better than another.
But they'd see the difference.
That's something I learned from watching him.
Some details are about making sure the roof works the way it's supposed to.
Other details are about taking the time to make the finished roof look right.
It was a premium way of installing a premium product.
How Would I Know to Look for That?
Most homeowners aren't going to know whether a standing seam roof is being installed the way I just described.
I wouldn't expect them to.
But you can ask the installer to explain how he's going to do it.
Ask how the panels will be finished at the eaves. Ask how he'll handle the valleys. Ask whether he uses Z-bars for the trim. Ask whether there will be any exposed fasteners on top of the roof.
And ask to see standing seam roofs he's already installed.
You don't have to know all the right answers before you ask the questions.
You're listening for whether the person you're talking to understands the system well enough to explain what he's doing and why.
If he starts talking about hemming panels, Z-bars, valleys, and keeping the fasteners concealed, those are things I'd listen for.
You don't have to know how to install the roof yourself.
But you can ask somebody to explain how he's going to do it.
Does Everybody Need Standing Seam?
No.
I think standing seam is the better roof. It's what I'd put on my own house.
But that doesn't mean everybody needs it.
If my brother was barely making it financially and needed a roof to keep his family dry, I wouldn't tell him he had to spend the money on standing seam. There are other roofs that'll do that.
The same thing goes for an old farmer putting a roof on his shop. If he doesn't mind checking the screws once in a while, exposed-fastener metal may make perfect sense.
Why would I try to talk him into something he doesn't need?
But if you're putting a roof on a nice home, you care about how it looks, you want less maintenance, and you have the money to spend, that's a different conversation.
That's where I'd start looking pretty hard at standing seam.
Standing seam is what I'd choose.
That doesn't mean it's the right roof for everybody.
Before You Decide...
Before you decide between standing seam and exposed-fastener metal, I'd think about what you're actually asking the roof to do.
What are you roofing?
A house and a shop don't necessarily need the same roofing system.
How long are you planning to own it?
How much maintenance are you willing to do?
How important is the finished look to you?
And what can you realistically afford?
Those answers matter more to me than simply asking which roof is better.
If exposed-fastener metal gives you what you need, there's nothing wrong with choosing it.
If the things standing seam gives you—hidden fasteners, less maintenance, and a cleaner finished look—matter to you, then spending more may make sense.
What do you need this roof to do?
Once you know that, the decision gets a lot easier.
Key Takeaways
Standing seam and exposed-fastener metal can both provide a good roof. The right choice depends on what you need the roof to do.
Standing seam's additional cost buys specific advantages, including concealed fasteners, less fastener-related maintenance, and a cleaner finished look.
A premium standing seam installation goes beyond keeping water out. Details like hemming panels, using Z-bars, concealing fasteners, and carefully planning panel layout are part of the craftsmanship you're paying for.
You don't have to know how to install standing seam yourself. Ask the contractor to explain how the eaves, valleys, trim, and fasteners will be handled.
Standing seam isn't the right choice for every building or every budget. Understand what matters to you before deciding whether the additional investment makes sense.
