| Having Advantages of Metal Roof Coating Materials |
There are a number of good reasons to use metal on commercial and
residential buildings. First, metal is a predictable and stable product.
Unlike other single-ply technologies like rubber, a metal panel is not
affected by ultraviolet (UV) rays, which are one of the leading sources
of roof degradation. Second, advances in metal coating and finishing
technologies have significantly improved the life cycle of metal roofs,
and the related cost benefits.
Metal roofing also is extremely puncture-resistant, which is a valuable
benefit to today’s building owner who is looking for long-term,
low-maintenance solutions. Actually, durability is one reason for
metal’s growing popularity. Many standing-seam roof systems have
earned a Class 90 wind-uplift rating . Some systems also carry a Factory
Mutual Class A fire rating as a result of their noncombustible surface.
Both ratings can help the building owner reduce insurance rates
substantially.
Metal roofing is extremely versatile. It is compatible with all types
of building materials and can be incorporated into all design con- cepts. Metal roofing is an effective accent for masonry, wood, stucco,
glass-curtain walls, marble, and granite. The various profiles make
metal panels easily adaptable for large and small projects. Commercial
structures typically are best suited to 18- to 24-inch-wide panel
configurations, while 8- to 12-inch-wide profiles are most often seen
on smaller structures, such as residential or smaller commercial
buildings.
Colors and finishes are available to suit any application, from earth
tones to exotic tropical hues, from bare, unfinished surfaces to special
coatings designed to resist corrosive atmospheres. These colors and
finishes have warranties for as long as 20 years. The premium architectural
finishes are highly resistant to fading and chalking. In addition
to the 20-year warranties available on some panel finishes, the
metal of the panel itself also carries warranties.
