Product Description

Our JM-1550 roof system will lend striking dimension to any architectural design. This versatile 1-1/2″ mechanically seamed panel can be curved to a wide range of radius applications – from barrel roofs to conical shapes and more. Concealed fasteners and a floating clip system reduce the effect of thermal stresses on the panels, helping to maintain a beautifully smooth, uniform appearance despite fluctuations in temperature.

Roof Seamers are available to rent from D.I. Roof Seamers


Can be installed over solid substrate, Installed over MetShield® underlayment, Installed over synthetic underlayment

Finishes and Warranty Info:

Aluminum Substrate

Our aluminum products are painted over prime, made in the USA, aluminum. We use multiple alloys and tempers to ensure that the products supplied will meet and/or exceed your requirements. We are big fans of using our painted aluminum products for coastal applications and have invested a lot of R&D funds to ensure our aluminum roof systems meet and/or exceed the high wind requirements. Our painted aluminum in salt environments does carry a 25-year warranty, however there are annual maintenance requirements.

Drexlume® Substrate

Drexlume is our version of mill finished Galvalume® with a two-sided, clear acrylic finish that is installed as a unpainted product. The clear acrylic is there to aid with roll forming and will weather away over time (no impact to the performance). Drexlume carries a 25-Year Non Pro-rated Drexlume Warranty (Acrylic Coated Galvalume).

Galvalume® Substrate

Our steel products are painted over prime, made in the USA, Galvalume, AZ50 and is all Tension Leveled for superior flatness. Galvalume is an aluminum/zinc coated carbon steel product that was designed specifically for building products and contains approximately 80% aluminum in the coating by volume. Galvalume offers much better cut edge protection than traditional hot dipped galvanized products. It carries a 25 year warranty against perforation.

Kynar Paint Warranty

35-year paint warranty on Galvalume® and Aluminum substrates. Our paint supplier, Valspar, is a market and innovation leader, therefore our Fluoropon (PVDF Resin also known as Kynar 500® and/or Hylar5000®) coating systems meet all ASTM physical property requirements.
