Quick answer
- Choose Horizon-Loc when you want a sleek standing seam look, concealed fasteners, and a more premium architectural finish for homes and high-visibility projects.
- Choose Panel-Loc Plus when you want a proven ribbed panel that works for roofing and siding, delivers strong value, installs efficiently, and fits shops, barns, garages, and many residential applications.
What each panel system is
Horizon-Loc: standing seam style metal panel for a premium finish
Horizon-Loc standing seam metal roofing panel is designed for a clean, modern appearance with vertical seams and a refined look. Standing seam systems are commonly selected when the roof is a major visual element and you want a high-end, minimal appearance.
Panel-Loc Plus: ribbed exposed fastener metal panel for roofing and siding versatility
Panel-Loc Plus metal roofing and siding panel is a ribbed panel designed to work across a wide range of building types. Ribbed panels are often selected for shops, barns, garages, and value driven installs because they are straightforward, durable, and versatile in both roof and wall applications.
The real differences that matter
1) Appearance from the street
- Horizon-Loc typically reads as modern and architectural. It is the panel choice when you want a premium finish that looks intentional and high-end on a home.
- Panel-Loc Plus typically reads as classic ribbed metal panel. It is the panel choice when you want a durable, familiar look that fits shops, barns, and many residential designs.
2) Fastener exposure and long term ownership feel
- Horizon-Loc as a standing seam style system is commonly associated with concealed fasteners and a cleaner finished appearance.
- Panel-Loc Plus is an exposed fastener ribbed panel system. Exposed fastener systems can be excellent, but owners should plan for periodic inspection of fasteners as part of normal building maintenance.
3) Best use cases
Best use cases for Horizon-Loc
- Modern homes and high-visibility residential roofs
- Projects where architectural curb appeal is a top priority
- Clean, minimal exterior designs where the roof needs to look premium
Best use cases for Panel-Loc Plus
- Shops, post frame buildings, barns, and garages
- Projects that need both roofing and siding panel compatibility
- Value driven builds where performance and practicality matter most
4) Install complexity and timeline
In general terms, ribbed exposed fastener panel installs tend to be simpler and faster than standing seam style systems. Standing seam projects often require tighter alignment, cleaner detailing, and careful trim execution to achieve the premium finish homeowners expect.
Practical takeaway: If schedule and install simplicity matter, Panel-Loc Plus is usually the easier lane. If finish quality and premium architecture matter most, Horizon-Loc is usually the better lane.
5) Roof and wall flexibility
If you need a consistent panel look across both roof and wall surfaces, a ribbed panel system is commonly selected because it carries well across building envelopes. That is why many shop and barn builds lean toward Panel-Loc Plus.
If your priority is the roof as an architectural feature on a home, Horizon-Loc often delivers the cleanest finished look.

How to choose in 7 practical questions
1) Is the roof a curb appeal feature or a functional cover?
If the roof is a key design feature, lean toward Horizon-Loc standing seam metal roofing panel. If the roof is primarily functional and you want reliable value, lean toward Panel-Loc Plus metal roofing and siding panel.
2) Do you want a modern architectural look or a classic ribbed panel look?
Modern architectural: Horizon-Loc. Classic ribbed: Panel-Loc Plus.
3) Will you use the panel on walls as siding too?
If you plan to panel both roof and walls for a shop or post frame build, Panel-Loc Plus is often selected for consistency across the envelope.
4) How important is installation speed and simplicity?
If speed and simplicity are critical, ribbed panel systems typically fit that need. If the finish quality and premium look matter most, a standing seam style panel is usually the better fit.
5) How exposed is your site to wind and weather?
Both systems can be excellent when installed correctly. In harsh exposure zones, the biggest performance gains come from correct detailing: edges, transitions, penetrations, and trim execution. Choose the panel that best matches your design goal, then insist on clean detailing and correct installation.
6) How complex is your roof geometry?
Complex roofs increase the importance of installer skill and a clean detail plan. If your roof has many valleys, dormers, and penetrations, prioritize the system your installer can execute cleanly and consistently.
7) What does your maintenance tolerance look like?
If you prefer the cleanest long-term ownership feel and the most refined look, Horizon-Loc is often the direction homeowners lean. If you are comfortable with periodic building inspection as part of normal ownership, Panel-Loc Plus can be a strong value choice.
