Even More Commercial Roofing Accessories: Metal Gutters, Two Way Vents & Various Custom Features! Are They Necessary For Your Commercial Building?

Roof penetrations are the single greatest threat to the integrity of the performance of your commercial flat roof. These protrusions affect everything from water flow to pooling and increase the risk of water-related structural damage. They’re the reason you need a regular roof maintenance plan for your commercial building. Thankfully, multiple commercial roofing accessories help you protect your investment from water and weather-related damages. 

The second installment of this two-part guide details additional commercial roofing accessories that eliminate these risks. 

Metal Gutter Systems

Commercial metal gutters are the best way to drain rainwater from your commercial property. At 6 to 8 inches wide, commercial gutters are bigger than residential gutters and can move a significant amount of rainwater in a short time. Properly installed metal gutters prevent water from pooling on the roof of your commercial building. They prevent flooding, structural roof damage, mold, and wood decay. 

Commercial gutters are typically strong, durable, and reliable because they’re made from aluminum, galvanized, or stainless steel. Aluminum gutters are available in different colors, are rust-resistant, and can hold a lot of water. However, they are lightweight and susceptible to physical damage. 

Steel gutters are the best choice for commercial properties because they can easily withstand anything mother nature throws at them. Galvanized steel gutters are strong, durable, and reliable. Galvanized steel is coated with a protective zinc layer to prevent rusting. Stainless steel commercial gutters stand a cut above the rest because they’re rust-resistant. Routine repair and maintenance are crucial to preventing rust and physical damage to your metallic gutters. 

Two-way Venting Systems

Installing two-way air vents on your commercial roof extends the lifespan of your roof’s membrane. The air vents reduce condensation and alleviate the pressure that often builds up between the roof deck and the membrane.

Blisters will form if moisture or air is trapped between the roof deck and the membrane or between the layers of the roof membrane. Since hot air expands, the blisters will grow bigger whenever the sun heats the roof. Eventually, the membrane may crack and expose your roofing structure to water damage. 

Two-way air vents allow the roof to breathe – they equalize the air pressure in your roofing system, which prevents blistering of the roof system. Air vent installations extend the lifespan of your commercial flat roof by maintaining its integrity and preventing water damage. 

Two-way air vents can be fabricated from exterior vinyl or lightweight metal such as aluminum. The vents are cylindrical and resemble a traffic cone with a flat cap. They should be installed at the high point of your roof between the roofing deck and the roofing membrane and sealed tightly.

Typically, you need at least one two-way vent for every 1,000 square feet of the roof, but each vent must be further than 7 feet from the building’s edge. The installation often entails heat welding the air vent’s skirt to the roof deck membrane.
