Metal panel roofing consists of several key components that work together to create a durable, functional system. These panels are available in various materials, finishes and profiles, each offering unique features suited to different construction needs. Understanding the individual parts, such as the panels themselves, fasteners, flashing and trim, is essential for selecting the right system for a specific project. As metal panel roofing continues to gain popularity, it’s important to explore how these components contribute to the overall performance and longevity of the roof.

This guide, created by Metal Central, provides insights into the basics of metal panel roofing and siding, explaining their roles in construction projects. As metal panels continue to rise in popularity, it is essential for professionals to understand their key features and advantages. By familiarizing themselves with the ins and outs of metal panels, contractors and builders can better serve clients and effectively incorporate this versatile material into their projects.  

Metal panel roofing

Metal panel roofing systems are well-regarded for their durability and resistance to the elements, making them a great choice for many types of buildings. Here’s a breakdown of the key components you’ll need:

• Panels: Metal roofing panels come in various profiles such as standing seam, corrugated and ribbed designs. These panels, typically made from galvanized steel or other metals, are known for their strength, long life and minimal maintenance needs. Metal Central locations offer 13 different panels for your home, business or other projects.

• Fasteners: Fasteners are essential for securing metal roofing panels to your building’s structure. They come in various forms like screws, nails and clips, each designed to ensure a secure fit while allowing for thermal expansion and contraction. Choosing the right fastener for your application is crucial for the longevity and performance of your roofing. We provide a range of screws and pop-rivets, with color-matching options.

• Trim components: Trim is used around roof penetrations, valleys and transitions to prevent water from seeping in and to protect vulnerable areas. For metal panel systems, metal trim is the best choice and is usually made to match your selected panel system. We offer a variety of standard and custom trim options, including vented trims, which you can design using our Central Link trim editor tool.

• Sealant: Sealant is applied to joints, seams and penetrations to ensure a watertight seal and prevent moisture intrusion. Common materials include silicone, polyurethane and butyl rubber. We offer a range of tube sealants, color-matching options and additional products like butyl tape and closures.

• Underlayment: Installed between the metal panels and the roof deck, underlayment provides extra protection against water intrusion and improves thermal insulation. Typical options include synthetic felt, asphalt-saturated felt and self-adhering membranes.

Metal panel siding

Metal panel siding is praised for its durability, versatility and visual appeal, making it a popular choice for both residential and commercial buildings. Here’s what you need to know about its main components:

• Panels: Metal siding panels come in various profiles, including horizontal and vertical orientations, ribbed designs and smooth finishes. While some panels can be used for both roofing and siding, others are specific to one application. Metal Central locations offer 10 siding panel profiles, including options for soffits in both vented and non-vented designs.

• Trim components: For siding, trim components like corner trim, J-channels and fascia are used to finish the edges and corners of the panels, giving a clean and professional look. These trims are different from roofing trims but serve a similar purpose in protecting against damage and providing structural support. We provide a variety of standard and special trim options for more complex needs.

• Fasteners: Just like with roofing, fasteners are used to attach metal siding panels to the structure. They come in different types and sizes depending on the panel profile and installation method. We offer various standard and special trims and fasteners, with options for vented components.

• Sealant: Sealant is also used in siding installations to create a watertight barrier at joints, seams and penetrations. Common sealants include silicone, polyurethane and butyl rubber. We have a range of tube sealants in color-matching options, as well as butyl tape and closures.
