The Homeowner’s Guide to Metal Roof Styles
When you're thinking of putting a metal roof on your house, there are a lot of decisions to make.
Which color, who will install it, what coatings to get. But one of the most important questions is what style of metal roof to use in the first place.
For homeowners, the right choice can elevate your home’s curb appeal and its long-term performance. The challenge is knowing which system fits your roof pitch, climate, and budget.
At Nu-Ray Metals, we make that decision simple. This guide walks you through the three main families of metal roofing—standing seam, snap-lock architectural, and exposed-fastener sheets—and shows you exactly which Nu-Ray panels fit each style.
Standing Seam Metal Roofing (Concealed Fastener)
Standing seam metal roofing is the standard for homeowners who want sleek, high-end looks and long-term performance.
With no exposed fasteners and continuous vertical seams, it’s built for both beauty and extreme weather resistance. These roofs are known for exceptional durability, clean design lines, and decades of near-zero maintenance.
What It Is
A standing seam roof features raised ribs and hidden clips that hold each panel in place. There are no exposed screws, giving you a continuous, watertight surface that’s as durable as it is sleek.
It’s the gold standard for homeowners who want maximum longevity, minimal maintenance, and modern curb appeal.
When to Choose It
- You want the lowest-maintenance, longest-lasting roof option.
- You live in a harsh-weather region—coastal, snowy, or high-wind.
- You prefer a clean, contemporary design aesthetic.
Nu-Ray Panels in This Family
- NRM-1000 – Architectural standing seam with 1.5" rib, 12"/16" widths, floating clip; minimum pitch 3:12.
- NRM-1750 – Snap-lock standing seam with 1.75" rib, 14"/18" widths; minimum pitch 2:12.
- NRM-2000 – Structural standing seam with 1.5" rib; works down to ½:12 pitch (factory sealant required below 1:12).

Quick FAQs
- Is standing seam worth it vs shingles? Absolutely. It can last 50+ years and requires almost no upkeep.
- What roof pitches work best? Some systems go as low as ½:12 (with sealant); others start at 2:12–3:12.
- Why do clips matter? They allow the panels to expand and contract naturally with temperature changes, preventing fastener fatigue and leaks.

Architectural Snap-Lock Panels (Clean Look, Faster Install)
Snap-lock panels give you that same clean, vertical-line look as standing seam but with simpler installation.
They’re popular among homeowners who love the aesthetic of concealed fasteners and want a quicker, more cost-efficient path to get it. This system bridges the gap between architectural beauty and real-world practicality.
What It Is
Snap-lock panels “snap” together along the seams, creating that same sleek standing-seam appearance—but with a simpler installation. They’re ideal for architectural projects where speed and precision both matter.
When to Choose It
- You love the standing seam look but want a faster or more cost-efficient installation.
- You’re roofing a home, canopy, or fascia with a pitch of 3:12 or greater.
- You want a premium look without the extra labor of field seaming.
Nu-Ray Panels in This Family
- NRM-6000 – 1" rib, 16" width, snap-lock profile for roofs, mansards, canopies, and fascia; minimum pitch 3:12.
- NRM-5000 – 1" rib, 12" width, snap-lock profile ideal for siding and fascia, with select roof applications (min pitch 3:12).
Quick FAQs
- Snap-lock vs true standing seam? Snap-lock systems fasten through concealed clips and “snap” together—great for aesthetics and cost. Standing seam requires mechanical seaming for the tightest weather seal.
- Where can I use snap-lock panels? Roofs, accent walls, and architectural features where pitch and exposure allow.
- What’s the required roof pitch? Typically 3:12 or higher for proper drainage.
Exposed-Fastener Metal Roofing Sheets (R-Panel / PBR / Corrugated)
Exposed-fastener roofing delivers strength, simplicity, and the iconic “metal roof” look recognized across generations.
It’s the go-to choice for homeowners who value practicality, speed, and the timeless charm of corrugated or ribbed panels. These systems are tough, affordable, and proven in every climate.
What It Is
These are the classic metal roofing sheets—corrugated or ribbed panels where the screws are visible. They’re durable, affordable, and iconic, delivering that “modern farmhouse” or “rustic cabin” feel while protecting your home for decades.
When to Choose It
- You want a budget-friendly metal roof with strong performance.
- You love the traditional, corrugated look.
- You have a simple, steeper roof (typically 3:12 or higher).
Nu-Ray Panels in This Family
- NRM-4000 – ⅝" rib, 36" coverage, anti-siphon groove; minimum pitch 3:12.
- NRM-4500 – ¾" bell-top rib, 36" coverage; cost-effective and versatile; min pitch 3:12.
- NRM-7000 – Structural R-panel with 1.5" rib, 36" coverage; built for strength and versatility.
- NRM-9000 – Classic 0.875" corrugated profile, 32" coverage (29" on roof), structural-grade steel.
Quick FAQs
- Do exposed screws leak? Not if installed correctly—gaskets and fastener spacing are key. Check and retighten every few years.
- What’s an anti-siphon groove? It channels water away from overlaps to prevent capillary leaks.
- Where does corrugated make sense? Ideal for barns, shops, cabins, or rustic-modern homes.

How to Choose: Style, Budget, Pitch, and Climate
Choosing the right metal roof starts with understanding how each system performs under different conditions. Think about your roof pitch, your budget, and the look you want—then match those priorities to the right category.
Here’s a quick way to compare your options:
Budget:
- Exposed-fastener: $ (lowest cost)
- Snap-lock: $$ (mid-range)
- Standing seam: $$$ (premium investment)
Roof Pitch:
- Standing seam: Works even on low-slope roofs (½:12 with sealant).
- Snap-lock & exposed-fastener: Typically 3:12 or steeper for best drainage.
Weather-Tightness & Maintenance:
- Concealed-fastener systems (standing seam, snap-lock) offer superior protection and minimal upkeep.
- Exposed-fastener panels perform well with routine screw inspections and maintenance.
Aesthetic:
- Standing seam → sleek, modern, architectural.
- Snap-lock → crisp, tailored, transitional.
- Corrugated/exposed-fastener → classic, rustic, timeless.
