Mechanical-Lock Standing Seam
Weather-Tight Design
The Interlock® Standing Seam Roofing System is a fully interlocking roof system. Its unique design forms a weather-tight unit.
It may be installed on new construction or applied over existing roofs. All trims and caps, are designed to ensure an integrated weather-proof roof.
Manufactured to any predetermined length, Interlock Standing Seam is composed of roll-formed panels with a ribbed contour to give added strength. A uniquely designed ridge on each panel provides a secure system of interlocking the panels together. The panels are coated with the Alunar® Coating System to provide an extremely durable and attractive surface.
Interlock Standing Seam Metal Roofs weights considerably less than most other types of roofing systems. No special preparation is needed, resulting in less structural cost.

The ceramic pigments in our exclusive Alunar® Coating System help reflect and emit the sun’s Ultraviolet rays. On a sunny day, these UV rays typically penetrate traditional roofing materials and greatly increase the temperature of your homes attic space resulting in higher cooling costs. Metal roofs can conserve energy by reducing cooling costs up to 25%*.

Comments

It doesn’t make sense to keep putting things on your house that you have to tear off and throw away 20 years later.
You know, I would rather spend more money on something that is going to last forever.
