Options Available When Installing A Low-Slope Roof On Your Commercial Building

Posted on: 9 January 2023

Flat or low-slope roofs are the norm for commercial buildings. In most cases, people prefer them over other types because they demand fewer materials and are multifunctional. For example, the initial construction cost of flat roofing is less than when you install a pitched alternative, as it takes up less space. Also, you can place your HVAC equipment, solar panels, and other essential equipment on its surface. That said, you should know that low-rise designs aren't perfectly flat but need a little slope for proper drainage. Here are three low-slope roofing options for your next commercial project. 

Modified Bitumen Membranes

Modified bitumen membrane roofs replaced traditional BUR or built-up systems. To make them, the manufacturers use asphalt or fiberglass to make a single sheet or numerous layers. Further, there are two distinct kinds of modified bitumen, each requiring a unique application process. As such, you can use a torch to melt the material, mop it down with hot asphalt, or use cold process cement during installation. Note that single-ply modified bitumen membranes are the standard for construction. In most cases, this variation is beneficial because it can withstand strong winds, reduces construction waste, and minimizes water intrusion into a building.

TPO Membrane Roof Systems

TPO is the ideal type if you are looking for an energy-efficient option. Further, thermoplastic membranes such as TPO don't harden as other systems do when heated. Instead, they melt and move, allowing membrane pieces to weld together using hot air. Note that they are both ultralight and highly reflecting due to their white color. In most cases, a white reflective membrane can significantly reduce cooling costs by deflecting the sun's rays in hot areas. Given this, this low-slope roof variation is one of the best installations for business in hot regions.

EPDM Membrane Roofs

You should know that this roof variation goes by ethylene propylene diene terpolymer or EPDM. Further, its malleability comes from being manufactured out of vulcanized rubber. That said, EPDM sheets are hard to join once the manufacturer makes and chemically dries them. You also cannot warm these membranes to a malleable state, so they need a roofing expert to place adhesives and seam the sheets together. In most cases, the roof is typically black, but you can also find a white variation. For installation, you can adhere the membranes to a permitted substrate and mechanically fasten them to the deck with screws and plates.

These are the three low-slope roof alternatives available in the market. If you are in the market for a commercial roof installation, consult a roofing contractor near you and hear what they say about each material. They can direct you to the ideal option and install it for you.
