Product Information

Polyurethane. Polyurethane sealants are resilient against moisture but are not very resilient against UV rays. This makes polyurethane sealants preferable in areas with more rain and snow than sun. Titebond Weathermaster sealant can be used for metal roofs, windows, doors, and more. It’s highly versatile, bonding strongly with various materials like Kynar™ coated metals, aluminum, galvanized steel, copper, PVC, wood, and more. It’s trusted and approved by Miami-Dade County and many other regions, a clear endorsement of its enduring strength. Silicone:Silicone sealants provide excellent UV and moisture protection. That said, they are fairly expensive and are somewhat difficult to apply to large areas, which doesn’t make this type of coating ideal for bigger projects.

Before we explore the top products, let’s understand what kind of sealants are best suited for metal roofs. The 4 Best Types of Sealants for Metal Roofs Roof sealants serve two main purposes: to protect your roof and to repair your roof. Depending on the product, roof sealants can provide a protective seal against moisture and sun exposure and can repair minor leaks before the leak creates serious damage. Although some roof sealants will be effective on virtually any type of roof, most sealants are formulated to work with specific roofing materials. The International Organization for Standardization (ISO) established the C1 to C5 certification standards to test and rate a sealant’s ability to withstand specific environmental conditions. A sealant with a C1 certification can only tolerate environments with minimal corrosive elements, like heated buildings with clean atmospheres. A sealant with a C5 certification can tolerate highly corrosive environments, like buildings with high levels of condensation or humidity and high pollution. However, I also like to advise users that there are various factors to consider before arriving at this decision. Always look at your budget, the affected area, the smoothness of the coating, and finally, your area’s temperature and weather conditions.

Stir contents for 30 seconds until it is thoroughly mixed. After first use, slight skinning may occur. If this occurs, remove the layer and stir contents for 30 seconds. Each sealant stands out for its unique properties, making it a valuable asset to any homeowner or roofing professional. However, it’s crucial to consider some important factors before getting started on your project. Factors to Consider When Repairing or Sealing Metal Roofs 1. Assessment by Professionals I’ve already mentioned that maintaining your sealed surface is key to durability, irrespective of the seal you decide to use. Resistance to UV rays is something worth considering with any roofing repair. Your roof will receive a great deal of direct sunlight. Sustained over many years, this can degrade your material of choice. Rubber, acrylic, and silicone sealants all reflect the sun’s rays well and are often offered in different color options. This makes color matching to your current roof fairly easy. Lighter colors tend to provide more UV resistance, which can improve theinsulating qualities of your roof.

Ultimately, the best way to seal a leaking roof is by replacing the defectivemetal roof paneling or shingles. New roof panels or components can come with manufacturer or labor warranties, which may cover repair costsin the future. However, in the event that you’re unable to fully replace your roof, we recommend using a quality liquid rubber sealant. These are typically the most cost-effective options for large and small repairs, and provide the best cross-section of protection capabilities. Roofs are designed to withstand an impressive onslaught of extreme weather. While they are designed for rough conditions, the daily exposure to sun, rain, hail, or snow will eventually degrade even the toughest roofs. When this happens, small leaks and penetrations can let in moisture that could result in expensive damage. In some cases, the damage could create the need for a new roof. As a caulk, it can access the small gaps created by damaged flashing, and the polyurethane sealant restores the flashing’s moisture-resistant function. It also functions as an adhesive, which means it will help close the gap between the flashing and the roof, which further assists in restoring a roof’s weather-resistant properties. This product isn’t the most versatile option on the list, but it serves its purpose of repairing metal roof flashing.The approximate shelf life of Gorilla Sealant is up to 2 years, unopened from date of manufacture. Once opened there is no standard time, it will be dependent on storage conditions and age of the product, up to 6 months is a good guideline.
