4 Reasons to Consider Textured Metal Roofing
With Montana’s unpredictable weather, your choice of roofing isn’t just about aesthetics—it’s a practical necessity. Metal roofing is an excellent choice to pair both style and substance to create a building that both looks good and stands up to the elements. But did you know you have the option to customize your metal roof’s texture, too? Textured metal roofing is another excellent way to upgrade your metal roof’s appearance and functionality.
Textured metal roof finishes have dramatically changed the metal roofing industry, giving you more options to tailor your roof to your personal preferences, architectural aspirations, and durability needs. If you are deciding between a textured or non-textured metal roof, we’ve got you covered. Let’s dive into the ins and outs of textured metal roofing and the four benefits you need to know.
What is Textured Metal Roofing?
Some think textured roofing refers to the type of metal panel you choose, like corrugated or tuf rib. Textured metal roofing actually refers to the finish painted on the metal panel of your choice.
Textured metal roofing, also called textured metal roofing finishes or crinkle paint, specifically pertains to the coatings or treatments applied to the surface of the metal. Textured metal roofing finishes are applied for aesthetic reasons—such as creating a textured look or simulating natural materials—or improving durability and weather resistance. Some common textured metal roofing finishes include granular coatings, textured paints, or specialized treatments designed to enhance the visual appeal or protective properties of the metal.
4 Benefits of Textured Metal Roofing Finishes
1. Less Glare
Textured metal roofing can help minimize the natural glare of a metal roof by diffusing the sunlight. This helps give the roof a more consistent, rich appearance. Also, textured paints measure between 2-3 on the gloss scale, so it is considered low gloss and, therefore, low glare.
2. Rich Appearance
Textured paint gives metal roofs an enhanced appearance by adding dimension and depth. There are a variety of texture options to choose from, so you can pick the texture that best fits your style or matches the style of homes in your neighborhood. Some types of topcoats for metal roofs can imitate wood, stone, traditional shingles, or other synthetic materials.
3. Color Retention
You want to make sure the color of your metal roof stays consistent over the years, and a textured finish can help with that. Textured metal paint strengthens metal roofs’ color retention and helps them resist fading and chalking in the long term.
4. Less Prone to Minor Damage
Because the surface of the panels is textured, textured metal roofing resists scuffs and scratches better than its non-textured counterpart. Additionally, textured metal panels are less prone to a type of deformation called “oil canning.” Oil canning is a wavy distortion that impacts the flat areas of metal panels, making them look less aesthetically pleasing. Textured panels help combat this distortion, thus improving the overall look of the roof.
Applications for Textured Metal Panels
Textured metal panels are incredibly versatile, so it can be used just about anywhere. However, we do not recommend using textured panels for projects that involve animal confinement. Textured panels contain galvalume substrate, which can react when exposed to ammonium vapors. You would be better to use a zinc-heavy galvanized panel instead of a textured one. Aside from this exception, you can use textured panels for a wide assortment of projects, including the following:
- Residential Roofing – Houses and residential structures often benefit from textured metal roofing, as it provides both durability and a stylish appearance. The various textures can complement different architectural styles, as well.
- Commercial Roofing – Many commercial structures—including offices, retail spaces, and industrial facilities—use textured metal roofing for its strength, low maintenance, and the ability to cover large areas
- Agricultural Buildings – Farms and agricultural buildings, such as barns and storage sheds, often use textured metal roofing for its weather resistance and longevity.
- Retail Spaces – Shopping centers and retail outlets often choose textured metal roofing for its modern aesthetic, easy maintenance, and the option to match the roofing to the overall design.
- Residential Additions and Renovations – Homeowners looking to add or renovate portions of their homes, such as garages or extensions, often turn to textured metal roofing for its practical benefits and aesthetic appeal.
Choosing the Right Textured Finish for Your Roof
When selecting the ideal textured metal roof finish for your project, it’s crucial to take into account both aesthetic preferences and practical requirements. Here are a few factors to consider when deciding on a texture:
- Desired Look – Whether it’s a subtle grain or a bold texture, find a texture that complements your building’s architecture.
- Climate – Take into account the climate of your region; opt for finishes that provide good weather resistance and UV protection.
- Maintenance – Choose a finish that not only enhances visual appeal but also contributes to the durability of the roof.
- Energy Efficiency – Explore energy-efficient options, as certain finishes can reflect sunlight.

What Is Sealant for Metal Roofing?
Metal roof sealant helps seal seams, joints, gaps, and other areas where water or air could enter a roofing system. Most gun-grade sealants are applied from a tube and form a bead over or within a joint. Depending on the formulation, the material may remain permanently pliable or cure into a flexible seal.
For metal roofing, flexibility matters. Panels naturally move as temperatures rise and fall, so a sealant used at a moving joint needs to accommodate that movement without losing adhesion.
The location of the seal matters too. A product used at an exposed seam may need different properties than one placed inside a concealed joint.
Sealant also should not be treated as a substitute for proper flashing, fastening, or panel installation. It works as part of the roofing system, not as a fix for a detail that was built incorrectly.
What Is Butyl Tape for Metal Roofing?
Butyl tape is a preformed sealing material typically installed between two roofing components. Instead of applying a bead from a tube, the installer lays a continuous strip of tape along the joint before the materials are fastened together. That makes it especially useful at concealed laps and other locations where two metal surfaces come together.
Butyl stays flexible, which helps it maintain a seal as a metal building experiences normal movement. There are also expanding sealant tapes that serve a similar purpose while filling irregular gaps and accommodating movement within the joint.
Sealant vs. Butyl Tape
The simplest way to think about the difference is application.
Gun-grade sealant works well when you need to apply a bead into a seam, joint, or gap. Butyl tape works well when you need a continuous seal between overlapping or adjoining components.
One is not automatically better than the other. The roof detail determines which type makes sense.
Metal Roof Sealant vs. Butyl Tape: Which Should You Use?
Different roof details put different demands on the sealing product.
These are general guidelines. Always check the roofing-system requirements and the manufacturer’s installation instructions before choosing a product.
4 of the Top Metal Roof Sealants and Butyl Tapes
The right product depends on the joint, expected movement, temperature conditions, and whether the seal will be exposed or concealed.
Here are four options GNMC has tried, tested, and trusts so much that we chose to carry them at our shop.
Best for: Expansion joints, lap seams, and joints that need to accommodate movement.
EMSEAL AST Hi-Acrylic Sealant Tape is a self-adhering, open-cell polyurethane foam tape impregnated with acrylic-modified asphalt.
Unlike a standard flat tape, EMSEAL AST gradually expands after it is removed from its packaging. That allows it to conform to the joint and fill gaps along irregular surfaces. For metal roofing and metal buildings, that can be particularly useful around details affected by thermal expansion and contraction.
Why It Works Well With Metal Roofing
One of EMSEAL AST’s biggest advantages is its ability to move with the building. The tape conforms to contours and maintains a seal as metal panels expand and contract. It is designed to help keep out dust, air, wind-driven snow, and moisture through joint details.
It also does not dry out and become hard or brittle over time. Because the material remains compressed within the joint, it is designed to stay in place rather than squeeze out the way some caulks or butyl products can.
Its resistance to UV exposure, aging, and mildew also makes it well suited to demanding exterior applications.
Common Applications
EMSEAL AST can be useful for:
- Expansion and compression joints
- Lap seams
- Mechanically fastened joints
- Irregular gaps
- Metal building details where movement needs to be accommodated
It can also be used alongside several common building materials, including metal, plastic, wood, and concrete.

Best for: Metal panel joints that need a permanently pliable, gun-grade sealant.
TFC BUTYL™ is a single-component butyl-based sealant designed specifically for strong adhesion to metal panels.
Its biggest distinction is that it remains permanently pliable. It does not skin over into a hard surface, which allows the material to continue moving with the joint after installation.
Why It Works Well With Metal Roofing
Metal panels do not stay perfectly still over the life of a building. Temperature changes create movement, and joints need a sealing product that can handle it.
TFC BUTYL remains flexible and moisture-resistant, which makes it useful for metal panel details where a rigid sealant would not be appropriate.
It also meets or exceeds AAMA 809.2 and is available in gray or white.
Installation Matters
Good adhesion starts with a clean surface. Before applying TFC BUTYL, the substrate should be dry and free from frost, oil, grease, incompatible coatings, or other contaminants that could interfere with adhesion.
The product is applied using a standard caulking gun and can be tooled after application if needed.
It is also worth paying attention to storage. TFC BUTYL should be kept in a controlled, dry environment below 75°F and used within 12 months of manufacture.
One other detail to know before choosing it: TFC BUTYL is not paintable.
Ask GNMC about TFC BUTYL™.
Best for: Seams, panel joints, and gaps that need a flexible cured sealant.
NovaFlex Metal Roof & Panel Adhesive Sealant is a single-component silicone sealant and adhesive commonly used as a seam sealant or joint filler in metal roofing and panel systems.
It is non-corrosive and non-sag, making it useful where contractors need a gun-grade product that will stay where it is placed.
Why It Works Well With Metal Roofing
Temperature range is one of NovaFlex’s standout characteristics. The product can be applied at temperatures from -20°F to 160°F and has a service temperature range of -40°F to 400°F.
That broad range is useful for metal roofing, where surfaces can experience substantial temperature swings.
NovaFlex also offers good adhesion to common building materials and can bridge gaps up to 3/8 inch. Its exterior weathering and aging performance make it suited to exposed building applications.
Where NovaFlex Makes Sense
Contractors may consider NovaFlex for:
- Metal roof seams
- Panel joints
- Joint filling
- Small gaps
- Details exposed to wide temperature swings
It remains flexible at temperatures down to -10°F and is freeze-thaw stable. There are a couple of limitations worth knowing before installation. NovaFlex is not recommended for joints that will be submerged underwater, and it should not be used on surfaces that will later be painted.
Cure time also depends on temperature and humidity, so installers should account for site conditions and follow the product instructions.
Contact GNMC about product availability.
Best for: Concealed metal building joints that need a continuous, flexible seal.
MB-10A Butyl Tape is an elastomeric butyl rubber sealant specifically designed around the requirements of metal buildings.
It comes extruded on silicone-coated release paper, which makes it straightforward to position during installation. It is also produced in different sizes and lengths to suit a range of applications.
Why It Works Well With Metal Roofing
MB-10A is designed to maintain its seal through normal building movement. Its combination of adhesive strength and cohesive strength helps the tape stay together and stay bonded as the assembly moves.
Temperature performance is another important benefit. MB-10A is designed to withstand extreme roof temperatures while maintaining compressibility in colder conditions. It also offers resistance to UV light and cold flow.
Those characteristics matter on metal buildings, where the material may experience a wide range of temperatures throughout the year.
Common Applications
MB-10A may be a good fit for:
- Concealed panel laps
- Metal building joints
- Overlapping components
- Details requiring a continuous butyl seal
- Joints affected by normal building movement
Choosing the right tape size is important. The joint needs enough material to create the intended seal without using so much that the tape squeezes excessively out of the detail.

What to Consider Before Choosing a Metal Roof Sealant
Before grabbing a tube or roll, look at what the joint actually needs and ask yourself the following questions:
- How Much Will the Joint Move? Metal panels expand and contract as temperatures change. A sealing product at a moving joint needs enough flexibility to accommodate that movement.
- What Temperatures Will the Product See? Metal roof surfaces can get hot, and Montana projects can also see very cold conditions. Check the product’s application temperature separately from its service temperature. A sealant may perform across a wide temperature range once cured while still having specific limits for installation.
- Is the Joint Exposed or Concealed? A concealed panel lap has different needs than an exposed seam. Butyl tape is often a practical choice where two materials are compressed together. A gun-grade sealant may make more sense when a seam or gap needs to be filled from the outside.
- What Materials Is the Product Touching? Always check compatibility with the metal substrate and any adjoining materials. A product that adheres well to bare metal may have different requirements around painted finishes, other coatings, plastics, or masonry.
- Will the Surface Be Painted? Some sealants are not paintable. Both TFC BUTYL and NovaFlex have limitations that should be understood before choosing them for a detail that will receive a finish later.
- What Does Installation Require? Good products still need good installation. Surface preparation, storage, bead size, compression, and cure time can all affect the finished seal. Read the product instructions before installation instead of assuming every sealant or tape works the same way.
Frequently Asked Questions About Metal Roof Sealants and Butyl Tape
What is the best sealant for a metal roof?
The best metal roof sealant depends on where it will be used. Gun-grade sealants can work well for seams and joints, while butyl tape is commonly used between overlapping components or in concealed joints. Movement, temperature, substrate compatibility, and exposure should all factor into the decision.
Is butyl tape good for metal roofing?
Yes. Butyl tape is well suited to many metal roofing details because it creates a continuous seal between components while remaining flexible enough to accommodate normal building movement.
Is sealant or butyl tape better for a metal roof?
Neither option is better for every application. Butyl tape is often used inside laps and concealed joints, while gun-grade sealants are useful for filling seams, joints, and gaps. Some details may use both as part of the roofing system.
Does metal roof sealant need to stay flexible?
For joints that experience movement, flexibility is important. Metal panels expand and contract as temperatures change, so the sealing product needs to accommodate the expected movement without losing adhesion.
Can you use any silicone sealant on a metal roof?
No. Use a sealant that is compatible with the roofing material, coating, joint design, and expected temperatures. The product instructions and roofing-system requirements should guide the choice.
