It all depends on what you’re looking for in a roof.
And it all depends a lot on what the roofing industry needs.
But the bottom line is: The most durable roofing material available today is fiberglass.
The American Association of Roofing Contractors says that fiberglass is the most durable material on the market today, and it’s one of the most common types of roofing in the United States.
The ASTM standard for roofing has been in use since the mid-1950s.
The latest ASTM standards were published last month.
It is the world’s standard, with the U.S. Department of Energy saying that the fiberglass used in roofing is more than 40 percent stronger than steel.
It is also stronger than aluminum and is lighter.
The American Society of Composites and Materials says that it is more durable than Kevlar.
It has a lower melting point and a longer lifespan than aluminum, and its coatings are resistant to water and dust.
Fiberglass roofs are also cheaper than metal roofs, and are generally more affordable than other types of roofs.
However, fiberglass has an added challenge.
It’s difficult to paint it, which can cause the roof to break and crumble under the weight of heavy rain.
In some areas, the ASTM says, fiberglas is more costly than aluminum.
In the United Kingdom, fiber to the meter requirements are tougher than in the U
