What is Metal Roofing? Uses, Types and Styles
In recent years, metal roofing has become an increasingly popular option for homeowners and building owners. Not only does it provide a sleek and modern look to any structure, but there are also many practical reasons to consider a metal roof. In this section, we will learn the benefits of choosing a metal roof over traditional roofing materials.
Durability is often cited as one of the primary reasons for selecting metal roofing. With its exceptional strength and resistance to harsh weather conditions such as strong winds, heavy rain, and snow, a metal roof can last up to 50 years with proper maintenance. This is significantly longer than asphalt shingles which typically have a lifespan of 15-25 years.
Another advantage of metal roofing is its low maintenance requirements. Metal roofs do not require regular repairs or replacements like other materials, making them a cost-effective long-term investment. They are also resistant to fire and do not crack or corrode easily.
When it comes to energy efficiency, metal roofs have the upper hand against traditional options such as asphalt shingles or clay tiles. The reflective surface of metal helps reduce heat absorption from sunlight, keeping the interior of buildings cooler during hot summer months. This results in lower energy costs for air conditioning.
Now let’s familiarize ourselves with some common terms and definitions associated with metal roofing:
1) Gauge: Refers to the thickness of the metal used in roofing sheets.
2) Rib: A raised portion on the surface of a sheet that adds structural support.
3) Seam: The joint where two sheets are joined together.
4) Standing Seam: A type of seam where one side overlaps the other creating a vertical ridge.
5) Corrugation: The wavy pattern created on sheet surfaces that give added strength.
Metal roofing has various uses and applications beyond residential homes such as commercial buildings, industrial warehouses, agricultural structures, etc. It can even be used for creative purposes like siding or accents on a home’s exterior.

Choosing the right type of metal roofing largely depends on factors such as location, budget, and desired appearance. While all these materials offer reliable performance and protection against the elements, consulting with a professional roofing contractor can help determine the best option for your specific needs. Metal roofing panels come in a variety of styles to suit different aesthetic preferences and functional needs. Among the popular options available are standing seam, exposed fastener, stamped profiles, snap-lock, mechanical seam, nail/fastener flange. In this section, we will take a closer look at each of these styles and their unique characteristics.
Metal Roofing Panels Styles and profiles
Standing Seam:
Standing seam metal roofing panels are known for their durability and clean appearance. They feature raised seams that interlock with each other creating a continuous panel without any visible screws or fasteners. This style is often used in commercial buildings but has gained popularity in residential settings as well due to its modern look. Standing seam panels can be installed using either concealed fasteners or exposed fasteners depending on the desired visual effect.
Exposed Fastener:
Unlike standing seam panels, exposed fastener metal roofing has visible screws or nails used to secure the panels onto the roof deck. This style is typically more cost-effective and easier to install compared to other types of metal roofing. Exposed fastener panels are also available in a variety of profiles including ribbed, corrugated, and multi-ribbed which can add dimension and texture to a roof’s appearance.
Stamped Profiles:
Stamped profile metal roofing comes in various patterns ranging from simulated shingles to tiles or slate designs. These profiles are created by stamping the metal into shape before it undergoes the finish coating process. Stamped profile panels offer an affordable alternative to traditional clay or concrete tiles while providing similar aesthetics.
Snap-Lock:
Snap-lock metal roofing features interlocking seams that snap together rather than using screws or nails for installation. This eliminates the risk of water penetration through exposed fasteners while offering strong wind resistance properties due to its tightly connected seams.
Mechanical Seam:
Mechanical seam metal roofing consists of two separate panels joined together with an interlocking mechanism called a seamer tool during installation. The result is a watertight seal that provides excellent protection against the elements. Mechanical seam panels are also known for their sleek appearance and are a popular choice in modern architecture.
Nail/Fastener Flange:
The nail strip roofing panel is a type of snap lock standing seam roof that does not require clips. The male flange features one inch slots spaced 6 inches apart and is fastened directly to the roof deck.
This standing seam system/nail Strip panel is considered one of the most cost-effective and simple to install options available. However, it’s important to note that eliminating the clips on this metal panel can result in reduced performance. Although it may be more expensive than an exposed fastener panel for a corrugated metal roof, the cost savings are only around fifty cents per square foot when compared to a higher performing product.
Choosing the right metal roofing panel style is essential in achieving both visual appeal and functionality for your structure. Each of these styles has its own unique features and benefits, making them suitable for different applications. By understanding these differences, you can make an informed decision when it comes to selecting the perfect metal roofing panel style for your project.
Most used Metal Thicknesses for roofing
When it comes to metal roofs, the material used plays a crucial role in its durability and longevity. The thickness of the metal is one of the key factors that determine how well your roof will perform in various conditions. Metal roofing materials are available in a variety of thicknesses, each with its own unique characteristics and advantages. In this section, we will delve into the different metal thicknesses commonly found in metal roofs.
The most common metal thickness ranges for residential roofs are 22 gauge, 24 gauge and 26 gauge. These measurements may seem small, but they make a significant difference in the performance of your roof.
Generally, thicker metals offer better protection against environmental elements such as rain, snow, hail, and wind. Moreover, thicker metals tend to have higher structural integrity and can withstand heavy loads without deforming or collapsing. For this reason, 22-gauge roofing is often used for commercial buildings where there is a need for additional strength and durability.
On the other hand, thinner gauges are more economical and suitable for residential structures with less demanding weather conditions. A 24-gauge metal roof can adequately protect against milder weather conditions while keeping costs down compared to its thicker counterparts.
For those looking for an even more affordable option or have specific aesthetic preferences, a 26-gauge metal roof may be ideal. Although not as strong as thicker options, this gauge still provides sufficient protection against typical weather patterns while also offering versatility in terms of style options.
It’s also essential to note that not all metals are created equal when it comes to strength and durability. For instance, steel roofing tends to be heavier than aluminum but offers better resistance against extreme weather events like hurricanes or tornadoes.
Panel Rib Rollers for metal panels (Striations)
Ribbed, V-Ribs, Bead, and Pencil are all essential when it comes to metal panel design and installation. These features not only add aesthetic appeal but also play a crucial role in the structural integrity of the panels.
Ribbed panels consist of parallel ridges or grooves running along its length. This design not only adds visual interest to the panels but also enhances their strength and rigidity. The ridges help distribute weight evenly across the panel, making them ideal for use in roofing and siding applications where reducing some the oil-cannig is key.
V-ribs, as the name suggests, form a V-shape along the length of the panel. This unique feature adds depth and texture to the surface while providing additional support to withstand heavy wind loads. V-ribs are commonly used in architectural designs to create a modern and sleek look.
Beads refer to small raised shapes or bumps on the surface of metal panels that run parallel or perpendicular to each other. These beads can vary in size and spacing according to design specifications. They add dimensionality to plain flat panels while strengthening them against dents and impacts.
Pencil Ribs are small ribs with round shape that provide an alternative option for achieving a ribbed look without too much emphasis on texture. Unlike traditional ribs that have a curved profile, pencils offer a subtle linear effect for a more refined appearance while still providing structural stability.
When using metal panels with these features, it is essential to ensure proper installation techniques for optimal performance.
Panel rib rollers are tools specifically designed for creating ribbed patterns on metal panels during manufacturing processes such as roll forming or bending. Using precision-machined steel roller dies with specific patterns based on your chosen profile ensures consistent results every time.
These rollers press into the metal sheet as it passes through them, forming ribs that meet design specifications. The key is to use rollers of the correct size and configurations for the desired rib spacing, height, and shape.
Ribbed, V-Ribs, Bead, and Pencil features in metal panels provide both functional and aesthetic benefits. When paired with quality-made panel rib rollers during manufacturing processes, they produce durable and visually appealing panels suitable for a wide range of applications.
