Galvalume steel roofing sheet has good heat and sunlight reflectivity. Its bright, white reflective surface makes it an ideal material for roofing. During the summer it makes buildings cooler by efficiently reflecting away sunlight and reducing the amount of heat transmitted into the building.

What are the advantages of a GALVALUME standing seam roof (SSR) compared to a built-up roof?
Leaking conventional, flat nonmetallic roofs are the biggest problem on nonresidential buildings for architects and building owners. Conventional roofs made with organic materials deteriorate even under normal environmental conditions. They embrittle from the heat and ultraviolet radiation from the sun. Then, as result of temperature fluctuations, they develop cracks, splits and tears. Finally, because they are flat, ponding water inevitably penetrates these brittle, cracked systems and leaks into the building, causing damage to goods and disrupting activities inside the structure. Leaks can be patched early in the life of the roof, but as time passes, leaks become more frequent and an expensive replacement of the roof is required. Such replacements often require tearoff, extra labor and even a temporary building shut-down. GALVALUME standing seam roofs (SSR) offer a weathertight, maintenance-free roof system that will last for decades on commercial, office and factory buildings. GALVALUME SSRs are economical to install, leak proof, maintenance-free, energy efficient, noncombustible and long-lived.
