Standing seam metal roofing systems offer premium resistance to high winds, heavy rain, hail, snow, and other extreme weather conditions. They also provide a critical layer of defense in the event of a wildfire. In addition to their performance capabilities, metal roof panels are available in a wide range of substrates, profile types, and colors, giving homeowners and contractors flexibility in both function and design.
With so many benefits, metal roofing systems present a durable alternative to asphalt shingles. However, beyond performance and aesthetics, one of the most important factors to consider during the planning phase is the warranty.
Manufacturer-based roof warranties provide assurance that the product or the system will perform as intended over time. They typically address key aspects such as manufacturer defects, material integrity, coating performance, and in some cases, installation. A well-structured warranty helps protect the long-term value of the roof and provides confidence in the selected system.
However, not all warranties are created equal, and understanding the differences is critical when comparing roofing materials.
In general, metal roofing systems offer stronger and more durable warranties than asphalt shingles. This is largely due to the longevity of metal and the advanced coating systems used to protect it.
Not only are asphalt roofs increasingly expensive to insure (particularly in parts of the country prone to extreme weather events), but asphalt shingle warranties are often sold as “limited lifetime,” a marketing term used to disguise that they are heavily prorated. Full replacement coverage is typically limited to the first 5 to 10 years, after which coverage decreases significantly, leaving homeowners on the hook for a larger share of any repair or replacement costs. Many also include exclusions that limit protection against severe weather events.
Metal roofing systems, by contrast, are able to offer more robust warranty options, but it’s important to note that not all metal roofing systems are the same. The strength of a warranty is directly tied to the quality of the materials used. Higher-quality metal roofing systems are able to offer stronger warranty protection because they are manufactured using premium raw materials and high-performance coatings. Drexel Metals, for example, uses American-made steel and aluminum along with Sherwin-Williams® PVDF paint systems formulated with Kynar 500® resin. These industry-best coatings are designed to resist fading, chalking, and degradation exceptionally well over time.
On the other hand, metal roofing systems that utilize SMP (silicone-modified polyester) paint systems do not offer the same level of durability. While they may still outperform asphalt shingles, SMP coatings typically have less robust performance characteristics and are more likely to carry shorter or prorated warranties starting after just 10 to 20 years.
When evaluating a roofing warranty, it’s important to start with the finish. The paint system serves as the first line of defense against UV exposure, moisture, and environmental wear. If the finish degrades, it can expose the substrate to corrosion and shorten the lifespan of the roof.
Drexel Metals stands behind its products with industry-leading warranties. Drexel Metals’ products are backed by non-prorated paint and substrate warranties for up to 35 years depending on the material selected and the environment. “Non-prorated” means the protection does not diminish as the roof ages. When a project qualifies for the Gold Standard Warranty, material and replacement labor costs are covered if the installed Drexel Metals painted product were to fail during the warranty period. On top of that, the Gold Standard Warranty is fully transferable from owner to owner, with no limit to the number of times the warranty can be transferred within the warranty period, helping further protect the roof’s value over time and even enhancing resale value. This level of coverage is made possible by the quality of the materials and coatings used.
It’s also important to understand how environmental conditions can impact warranty qualifications. Standard finish warranties are designed to protect against natural weathering, such as fading and chalking, but may exclude corrosive environments, including areas exposed to saltwater or salt spray. In these areas, additional considerations such as substrate selection and system design may be required. Within a certain distance from a salty environment, Drexel Metals may require the use of an aluminum substrate and a prescribed freshwater rinsing routine, to ensure the best durability possible and to maintain warranty coverage.
With a wide range of materials and project conditions to consider, there is no single warranty that fits every application. Instead, Drexel Metals offers a variety of warranty options designed to suit different needs, allowing contractors and homeowners to select the right protection based on the environment and system design.
Understanding the relationship between material quality, environmental exposure, and warranty structure is key to making an informed decision. It is essential to review warranty terms carefully to ensure you are choosing the appropriate metal system for your specific environment.
Designed to last two to three times longer than asphalt systems, metal roofing delivers superior durability, performance, and long-term value. These advantages are what make it possible for high-quality metal roofing systems to offer stronger, more reliable warranties, providing lasting confidence for both contractors and homeowners.
“That’s why I use Drexel Metals,” said Jeremy Wood, the contractor who replaced an asphalt roof with a metal roofing system on a historical landmark property in St. Petersburg, Florida. “The panels are American-made, the warranty is clear, and they actually honor it.”
