Stainless Steel for Exteriors and Roofing

Stainless steel is emerging as a material of choice in building construction. Its longevity is without question. Recycling statistics are impressive. Finishing methods offer substantial variety. While the majority of architectural applications of stainless steel have been for interior elements like elevators, the recent shift toward sustainable materials has propelled the use of stainless steel as a building envelope.

Stainless steel offers greater residual and resale value with lower maintenance costs as it does not require repainting, resurfacing, nor does it require replacement, when properly specified and installed.

Stainless steel lasts indefinitely without coatings that can emit volatile organic compounds (VOCs) as in painted surfaces. Stainless has no leaching or runoff as with less stable materials. In addition, when the building is no longer in service it is highly likely that the materials will be recycled, generating long-term value to the building owner.

Adding a Micro Texture

By adding a micro texture to stainless steel for exterior and roofing applications, the benefits of using this material increase tenfold. A low glare stainless steel finish, like Contrarian’s InvaiMatte®, is easy on the eyes, even in direct sunlight, which makes it ideal for roofing applications. Its unique finish, which involves no coatings, is rolled directly into the surface of the metal. Learn more about the benefits of InvariMatte® on roofing applications, here.


While it does have a muted appearance, the InvariMatte® texture allows just enough reflection to take on the colors of the environment around it. InvariMatte® retains its original beauty over time without developing a patina.


Perhaps one of the biggest benefits of using micro textured stainless steel is its enhanced durability. It is capable of lasting the life of the building (resisting corrosion, fire, wind and hail). Additionally, it can be welded, creating stronger, more durable joints.

Energy Saving & Environmentally Friendly

Stainless steel is a very efficient reflector of solar energy, substantially reducing insulation requirements. Unlike other bare metals that patina, or paints that oxidize, stainless steel retains all of its original solar reflectivity and energy efficiency for as long as it remains installed. Stainless steel comes from 75% recycled content and is 100% recyclable without downgrading. Additionally, stainless steel creates no biocide runoff, unlike copper, zinc and lead.
