One of the most notorious benefits of durable corrugated metal roofing solutions is their longevity. With proper care and maintenance, they can last anywhere from 40 to 70 years, protecting your property against inclement weather.
Although corrugated metal roofing is naturally resistant to moisture, mold, and pests, it still needs care during and after installation to meet its expected lifespan. Hence, sealing it to finish the installation is common in the industry.
Sealants help protect your roof against water, UV rays, and excessive moisture, prolonging their life and ensuring you don’t run into leaks and cracks down the road. Likewise, they can be used to repair minor cracks and holes in affordable corrugated roofing panels to preserve their functionality without costing you a fortune.

Understanding metal roofing sealants
Sealants are classified by their base material. Hence, you’ll mostly find two categories of roofing sealants: water-based and solvent-based sealants. Solvent-based sealants are more expensive and more complex to apply. But achieve more durable corrugated metal roofing solutions than water-based sealants.
Some water-based sealants are those made from acrylic or some varieties of silicone. Though these are mainly used in low-performance applications.
Conversely, solvent-based adhesives are commonly made from silicone, rubber, and polyurethane. However, the last one is not usually recommended in corrugated metal roofing since it’s prone to becoming stiff in cold temperatures and pulling away from the roof.
4 best metal roof sealants according to roofers
The following sealants were chosen according to their ease of use and reported performance for crack and leak repairs. However, remember that this list is not exhaustive, and your contractors may use different sealants to spray coat the entire roof.
1. Nova flex
This is a popular brand of metal roofing sealants, well-known for its performance when repairing small leaks and sealing gutters. The Novaflex sealant is thinner than other brands, forming an even, watertight seal once applied. It works well with corrugated metal roofing made from copper or aluminum.
This sealant is easy to apply, usually only requiring a caulking gun, and suits residential and commercial roofs.
2. Titebond
Titebond is a renowned brand in the roofing community for its resistance to harsh weather conditions and UV rays. You can also apply it with a caulking gun. Titebond adheres to all metals, from affordable corrugated roofing panels to copper roofs. Though you must first coat the roof to adhere to copper properly.
You can also use Titebond sealant for flashing and siding.
3. GAF Flexseal Caulk
People know this solvent-based synthetic elastomeric sealant for its durability and strength. It works with all roofing materials, including corrugated metal roofing.However, it suits applications where caulk is typically used, such as flashings or edge metals.
4. Geocel 4350
The Geocel 4350 sealant is notable because of its color variety, which allows it to match different roofs instead of the typical gray-white sealants. This product provides a waterproof sealant that resists shrinking under hot temperatures and suits almost every type of durable metal roofing solution.
5. Gibraltar butyl tape
All the previous sealants are liquid solutions to apply with caulking guns. Hence, it’s time to highlight one sealant tape that is helpful to seal metal trims: Gibraltar. This sealant tape resists UV rays and moisture, and stays flexible over time on most corrugated metal roofing types.
However, experts do not recommend using butyl sealant tape for joints with high movements or for waterproofing structural elements if the panels are misaligned or corroded.
Which roof areas should you waterproof with sealants?
Roof sealants increase your roof’s water protection by preventing rainwater from entering and causing damage. Thus, some of the most common areas to seal during a new installation and for repairs are:
● Fasteners
● Gutters
● Downspouts
● Joins
● Trims
● Nails
● Gaps in your roof
Ensuring your roofers seal these crucial areas during the installation or replacement is crucial to guaranteeing durable corrugated metal roofing solutions for years to come.
Still, it is also important to remember that most sealants last about 10 – 20 years, so you’ll likely need to reseal your flashings, gutters, and fasteners several times throughout your roof’s lifespan.
