Classic Metal Roofing's product catalog includes two standing seam systems, slates, shingles, shakes, and tiles. The panels are made from recycled aluminum and steel materials and come in many colors, sizes, and finishes.

Classic Metal Roofing has one of the most comprehensive lifetime limited paint warranties, which applies to all its products. It covers manufacturing defects and any peeling, cracking, flaking, chipping, or splitting. Moreover, it covers chipping and leakage caused by hail.

The warranty is transferable when the original owner sells the property for up to 40 years from the time of installation. Unlike other warranty programs, this one transfers each time the house sells as long as it is within 40 years.

Additionally, Classic Metal Roofing also offers a 30-year fade and chalk resistance warranty. However, it only applies to products with a PVDF resin-based coating.

The Universal Standing Seam is made from US G90 Galvanized steel with a PDV coating. It features a snap-action seam where hems conceal fasteners.

Variety of Products

Everlast Roofing offers the least number of options in metal roofing with only two standing seam panels and four exposed fastener systems. ASCBP has the largest product catalog with three standing seam panels and seven exposed fastener panels.

Classic Metal Roofing is a few panels shy of equaling ASCBP's number. However, it stands out for its five specialty metal roofing systems. It beats the rest in versatility by including metal slates, shakes, tiles, and shingles into its product catalog.

Quality of Products

All companies have ensured that their roofing products are of the highest quality. That includes incorporating high-quality substrates and finishes.

ASCBP's products feature Galvanized and Galvalume substrates with PVDF and SMP finishes. Likewise, Everlast Roofing’s panels incorporate PVDF and high-quality SMP finishes. However, they come in varying substrates, including GF90, G90, AZM125, and AZM 110.

The AZM substrate features the traditional aluminum and zinc coating but adds magnesium. The result is a coating that works better than Galvalume in protecting the panel against rusting and corrosion.

All Classic Metal Roofing products come with PVDF finishes. That is either Kynar 500 or Hylar 5000 PVDF resin-based finish. Save for one, all its panels consist of 99% recycled aluminum, making them the most appropriate for coastal environments.

Customer Support

All three companies do an excellent job in offering support to their customers. Apart from being available to answer questions, they also provide resources and tools. These include educational courses, articles, videos, downloadable PDFs and brochures, photo galleries, and color visualizer tools.

Ease of Purchase

All companies sell their products through independent dealers and distributors spread across the country. To buy, you need to visit their websites to search for names, addresses, and phone numbers of distributors near your location.

ASCBP makes it easier for distributors by creating an online ordering system. Here, they can get quotes, place orders, and check the status of their orders. They can also review the history of orders they have made in the past.


ASCBP, Everlast, and Classic Metal are top-tier metal roofing manufacturers in the country. They all offer high-quality metal roofing products, but they differ in more ways than one.

ASCBP has the widest product catalog, while Everlast has the least. However, the latter offers the broadest variety of substrates and finishes.

Classic Metal demonstrates the most versatility with five specialty metal roofing systems. It also has the best warranty programs.

There are many factors to consider when picking a metal roofing manufacturer. Ultimately, however, who you work with will depend on your unique roofing needs and personal preferences.
