Need a Commercial Roofing Company in Houston?

If you’re in the process of constructing a new building, or planning the replacement of an outdated roof on an existing building, there are four main types of commercial roofing systems to consider:

TPO (Thermoplastic Olefin or Polyolefin) Roofs

TPO roofing systems 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. Most TPO systems meet and exceed the new “green roof” reflectivity ratings in municipal and architectural specifications. TPO systems can be fully-adhered or mechanically fastened, depending on the application. These systems are highly resistant to tears, impact, and punctures with good flexibility to allow for building movement. The TPO system has proven to be an excellent over-lay application for an existing built-up roof.

EPDM (Ethylene Propylene Diene Monomer) Roofs

EPDM systems have taken a back seat in the single-ply market to TPO, PVC, and other “green roof” systems”. Because EPDM is a rubber roof, it has more market volatility, and therefore has been priced out of the single-ply equation. This roofing system is extremely durable, but EPDM lacks the reflectivity ratings of its counterparts.

Built-Up (BUR) Roofs

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. Wood decks require a rosin sheet and base sheet, steel decks must be at least 22 gauge, cement fiber require a base sheet or mechanically-attached insulation. There is no substrate requirement when applying BUR to a concrete deck.

Metal Roofs

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.
