Why Delta Metals Uses NovaFlex Metal Roofing Adhesive Sealant


It is easy for roofing sealant to be easily overlooked. However, it is one of the most important factors for a roof to have a long lifespan. With the roof taking the brunt of outside elements like wind, rain, snow, and UV rays, it can quickly become worn without sealant. To keep a building secure and free from damage, including sealant in your next metal roof installation is imperative. Today, we want to look at how to insulate metal buildings properly, why sealant is important, and which features are most desirable. 

What is Roofing Sealant and Why is it Important?

Roofing sealant is specifically designed to help seal cracks and serve as a protective barrier. It can be used to patch holes, repair damaged panels, and keep elements from penetrating the roof. When you are installing a new roof, the sealant is important to help you seal flashing or attach the panels together. If preventing a leaky roof is one of your top priorities, utilizing roofing sealant is one of the best courses of action. For flat roofing systems, the sealant is imperative. Without it, standing water will be sure to create significant damage. 

These adhesive coatings can be a pivotal element in keeping a home safe from outside elements. Roofing sealing is often weatherproof and can offer protection in any climate. Damage from the sun’s UV rays can cause a roof to fade in the color, warp, or wear out. When these problems do occur, the owner will likely be unaware of it until there are major consequences. To prevent the worst from happening, applying a roofing sealant will work to prevent damage in the first place. While roofing sealant may seem like an unnecessary element, it is a surefire way to extend a roof’s lifespan and decrease the risk of damage. 

Another important aspect to consider is how roofing sealant can impact your cooling system. When it comes to the color of the roofing panels, the lighter the color, the less heat the roof absorbs. When a light-colored roof is installed, it greatly decreases the amount of energy a cooling system will need to use in warmer months. A darker roof color will make the cooling system work harder, increasing utility bills. Similarly, the color of the sealant can have the same effect. When you choose a lighter color sealant, it can help reflect sunlight and ensure the home is more energy efficient. 

Types of Sealants Materials

When a metal roof installation is completed correctly, it can last a lifetime. Choosing the right sealant can be the extra line of defense that protects a roofing system from major water damage. Each type of sealant can vary in composition, however, it will either come in the form of a gun caulk or butyl tape. With the caulking form, it can come in acrylic, polyurethane, or silicone. 

Silicone is the preferred sealant method for a metal roof installation due to its superior adhesive abilities. Metal and other construction materials can be difficult to stick to, but silicone sealant can do the job with no problems. On top of that, silicon provides excellent water and UV protection. Preventing the roof from outside elements that could cause damage is one of the most important reasons to install sealant. When you choose to work with silicon sealant for a metal roof installation, you will be ensuring that the highest quality of materials are used on your project.

NovaFlex's Key Benefits

It can seem like all materials are created equally, especially when it comes to metal roofing sealant. However, NovaFlex has features that set it apart from its competitors. Here are some of the reasons why we prefer NovaFlex’s adhesive sealant for a metal roof installation. 


One of its most important qualities is its waterproof nature. While it is not recommended for the sealant to be submerged in water, it is extremely water resistant and will serve as a barrier during rainy weather. As a result, it can resist mold and mildew that could damage the roof over time. A roof should be able to withstand storms and drain excess water. With the proper sealant, the roof will operate correctly. 


While you cannot paint over NovaFlex sealant, they offer over 70 colors, including translucent, that were matched to popular industry-standard metal roof colors. On top of that, the color will never chalk or fade. If you are looking for a sealant that will perform well while still coordinating with the color of the panels, NovaFlex is a great choice. This general-purpose material can also be used in numerous areas. Metal roofs, it is frequently used as a seam sealant or joint filler. However, it is not limited to those two areas. Here is a list of roofing components that NovaFlex adheres to. 

  • Lap Joints
  • Pipe Boots
  • Trim
  • Copper (exposed areas)
  • Metal Siding
  • Stucco
  • Roof Flashing
  • Downspouts
  • Termination Bars
  • Metal Roof
  • Snow Guards
  • Single-Ply
  • Gutters

Metal roofs need to expand and contract with changes in temperature. As the roofs move, the sealant should be able to move with it. This ensures that every seam and crack remains properly covered instead of exposed to outside elements. NovaFlex’s sealant is extremely flexible and will be able to keep a roof protected at any temperature. 


Above all, NovaFlex offers one of the most durable metal roof sealants on the market. As a contractor, you understand a roof should be strong to withstand any outside element to keep what is inside safe. This sealant will only strengthen the roofing system to further protect the building from any damage. 

When it comes to sealant, a roofing contractor should understand the pros and cons of each type and how to insulate metal buildings properly. Choosing high-quality materials will ensure you are providing your clients with the best installation possible while proving that you work at the highest standards. Excellent adhesion is crucial for any roof to guarantee a stable, durable, and long-lasting metal roofing installation.
