TPO roofing systems (shown in picture) are among the fastest growing in the commercial roofing industry. Made of durable material with low-temperature flexibility and a high-temperature tolerance, these systems are exceptionally resistant to ultraviolet, ozone and chemical exposure. These systems are highly resistant to tears, impact, and punctures with good flexibility to allow for building movement.
EPDM is a rubber roof, therefore, it has more market volatility. This roofing system is extremely durable, but EPDM lacks the reflectivity ratings of its counterparts.
One of the oldest and most reliable roofing systems is the built-up system. Usually characterized by the ballast finish, BUR is made by layering several plies of roof felts with bitumen in between. This laminating effect uses the felt as the strength of the roof structure and the bitumen as the waterproofing. The layers combine to form a watertight barrier that exhibits exceptional heat and wind resistance.
Built-Up Roofs are ideal for flat or nearly flat surfaces and can be installed over most roof decks.
There are many different metal roof styles and designs. The greatest advantage of a metal roofing system is the durability. Metal roofs can withstand large diameter hail, extremely high winds, and are impervious to temperature extremes. Metal roofing systems are also very lightweight in comparison to some of the other commercial roofing systems available. These systems can also be more aesthetically pleasing and have seen a surge in architectural appeal in recent years.
