Metal roofs are among the most resistant in any climatic conditions, and this is due to the properties of the materials from which they are made.

When installed properly, a metal roof should last as long as the building itself, providing protection against water infiltration, withstanding strong winds and preventing snow accumulation. The metal is resistant to fire, mold, insects and rot. The warranties vary widely, but most metal roofing San Antonio companies guarantee their products for 20-50 years. Paint finishes typically have 30-year warranty.

Metal sheet roofs are lightweight, fast to install, and can be applied to an existing roof without the need to take out the existing system or adding more structural support.

Because metal roofing materials are non-combustible, they usually have a higher fire-resistance. Also, the metal reflects the sun`s radiant heat, minimizing the heat gain as well as the damage caused by sun exposure.

Metallic coverings can be installed even on flat roofs providing the same great protection, because the smooth and slippery surface of the metal does not retain water or snow on the roof. Also, the way metal tiles and panels are fastened contribute to their overall efficiency and make the roof stand for a very long time.
