If you’ve driven around neighborhoods across Maryland lately, you’ve probably noticed more homes sporting shiny metal roofs. It’s not just a trend, it’s a smart upgrade. Metal roofing has become one of the most popular options for local homeowners who want something that lasts longer, looks sharp, and can handle the region’s unpredictable weather.
But if you’re new to metal roofs, one question usually comes up first: “Which type of metal roof should I choose?” There are several types, but two main ones Maryland homeowners go for:
Standing Seam Metal Roofs (Hidden Fasteners)
Screw-Down Metal Roofs (Exposed Fasteners)
In this article, we'll break them down for you. We’ll compare the most common types of metal roofs, how they differ, and which might be best for your home in Montgomery County, Howard County, or anywhere in Maryland.
The Two Main Types of Metal Roofs
There are plenty of metal roofing styles, but when it comes to residential homes, two types lead the pack:
Standing Seam Metal Roofs (Hidden Fasteners)
Screw-Down Metal Roofs (Exposed Fasteners)
These two systems might look similar from a distance, but how they’re built, and how they perform, makes a big difference.
Standing Seam Metal Roofs: Sleek, Modern, and Built to Last

Standing seam metal roofs are known for their smooth, modern look. The panels run vertically along your roof and lock together at raised seams, hiding the screws underneath. That’s why they’re also called hidden fastener roofs.
Because the fasteners are concealed, the panels can freely expand and contract as temperatures change — something especially important in Maryland’s climate, where summers can get muggy and winters can be freezing.
Advantages of Standing Seam Metal Roofs
Clean, contemporary appearance with no visible screws
Resistant to leaks since fasteners aren’t exposed
Lasts 30–50 years, sometimes longer
Very low maintenance
Great for solar panel installation or “cool roof” coatings
Drawbacks
Higher upfront cost
Must be installed by experienced professionals
Standing seam metal roofs are ideal if you’re after longevity and a modern look. They’re especially popular on newer homes in suburbs like Silver Spring and Bethesda, where homeowners want durability and curb appeal.
Screw-Down Metal Roofs: Tough, Practical, and Budget-Friendly

A screw-down metal roof, also called an exposed fastener roof, is the simpler, more affordable cousin of standing seam. The panels are screwed directly into the roof decking, with washers under each screw to seal out water. You can see the screws on top of the panels — hence the name “exposed fastener.”
This type is common on garages, barns, and small homes, but it’s also used on budget-conscious residential projects.
Advantages of Screw-Down Metal Roofs
More affordable than standing seam
Easier and faster to install
Provides strong protection against wind and rain
Drawbacks
Screws can loosen over time from temperature changes
Requires regular maintenance (tightening or replacing screws every 5–10 years)
Shorter lifespan (around 20–30 years)
If you’re okay with a bit of routine upkeep and want to save some money upfront, a screw-down roof can still serve you well. It’s a sturdy choice for homeowners who value function over fancy looks.
Standing Seam vs. Screw-Down: Side-by-Side Comparison
Side-by-side photos of a standing seam metal roof with hidden fasteners and a screw-down metal roof with exposed screws on Maryland homes.
| Feature | Standing Seam Metal Roof | Screw-Down Metal Roof |
|---|---|---|
| Fasteners | Hidden under the panels | Exposed on top |
| Appearance | Sleek and modern | More industrial or rustic |
| Lifespan | 30–50 years | 20–30 years |
| Maintenance | Minimal | Regular screw checks needed |
| Leak Resistance | Excellent | Moderate (depends on maintenance) |
| Average Cost in Maryland | $14–$18 per sq. ft. | $5–$10 per sq. ft. |
| Best For | Homes, modern builds, long-term value | Garages, sheds, barns, tight budgets |
If you plan to stay in your home long-term, the extra cost of a standing seam roof often pays for itself with less maintenance and fewer repairs over time.
Other Types of Metal Roofs You Might See Around Maryland
Three metal roof types on Maryland homes: corrugated metal, stone-coated steel, and copper with patina.
While standing seam and screw-down systems dominate, there are a few other metal roofing options worth knowing about:
Corrugated Metal Roofs
These have a wavy pattern and are often used on rural or rustic-style homes. They’re affordable and easy to install, but the visible screws mean more maintenance over time.
Stone-Coated Steel Roofs
This combines metal durability with the appearance of traditional shingles or tiles. It’s a great option if you like the shingle look but want the strength of steel.
Copper and Zinc Roofs
These premium metals are stunning — and pricey. Over time, they develop a natural patina that protects the surface and gives them a distinctive aged look. Homes in older, historic Maryland neighborhoods sometimes use copper roofs for that elegant touch.
Cost of Metal Roofs in Maryland
Metal roofing prices vary based on size, slope, and material, but here’s a general estimate for Maryland homes:
Screw-down metal roof: $5–$10 per sq. ft.
Standing seam roof: $14–$18 per sq. ft.
Copper or zinc roof: $30–$50 per sq. ft.
Yes, it’s an investment; but remember, a metal roof can last two or three times longer than asphalt shingles. That means fewer replacements and repairs down the line.
Lifespan and Maintenance Tips
Here’s the truth: both types of metal roofs can last for decades if you take care of them.
Standing seam roofs need very little attention. A yearly inspection and debris removal are usually enough.
Screw-down roofs need more frequent maintenance. You’ll likely need to replace or tighten screws every 5–10 years to prevent leaks.
Because Maryland sees everything from summer humidity to winter snow, it’s smart to schedule seasonal roof checks, especially after major storms.
Warranties and Paint Finishes
Most metal roofs come with a paint warranty, often lasting around 30 years. The most common is the Kynar 500 finish, which helps keep the color vibrant and prevents fading or chalking from UV rays.
Keep in mind that some warranties cover the paint, not necessarily the entire roof system. Always ask your roofing contractor about both material and workmanship warranties before signing anything.
Which Metal Roof Is Best for You?
Here’s the simple answer: it depends on your goals.
If you want a long-lasting, low-maintenance roof that boosts your home’s value, go for a standing seam metal roof.
If you’re working on a tight budget or roofing a smaller building, the screw-down system might be just what you need.
For homeowners in Maryland, both types hold up well against local weather. The key is professional installation and consistent maintenance.
