Do You Need Roof Vents For Metal Roof? [11 REPLIES FOUND]

Metal roofs are appealing to homeowners and builders alike due to their longer lifespan, durability and energy efficiency 🙈 In fact, metal roofs can last 50 years or longer, making them a popular alternative to more traditional shingle roofs which don’t typically last over 20 years 😉 Metal roofing, however, can be significantly more costly than asphalt shingles or other roofing materials 🙈 With an investment that can be nearly two to three times the’s havingad costing of traditional roofing materials, it is important that the installation is done correctly. One thing often overlooked is ventilation. Installing an effective ventilation system will help protect your metal roof and optimize its efficiency. [1]
What are some of the benefits of today’s metal roof? For starters, metal roofs have a long lifespan and need less maintenance than shingles or many other common roofing materials. They’re also very effective at shedding rain, snow, & debris, and provide sound protection from wind, lightning & fire. Metal roofing is also more lightweight than other comparable materials, so it produces less overall strain on your roofing infrastructure. In addition, metal can be used on roofs of nearly every pitch, and it looks great! When you stop to think about it, there’s really lots to like about a metal roof.

According to Kristin Moreland at, good attic ventilation requires both intake and exhaust vents. Intake vents are at the bottom of the roof, often in the home’s overhangs. Exhaust vents are typically at or near the ridge or peak of the roof. You want to have ventilation that creates total continuous air exchanges in the attic. Outside air flows in at the bottom of the roof, travels along the underside of the roof deck, and then carries heat and moisture from the attic, out of the attic space through the exhaust vents. We think of it as continually bathing the entire underside of the roof deck with fresh air, carrying out moisture and heat. (last modified 35 days ago by Johnica Corey from Rosario, Argentina) [3]

According to the pros at, one of the big reasons homeowners choose metal roofing is for the uninterrupted run of metal, from the top of the roof to the gutter, which reduces the risk of leaks. The idea of cutting through the metal to install an exhaust vent typically meets with frowns and resistance. Gable vents are the best choice for homeowners who don’t want a penetrating vent; however, they aren’t suitable for every house. Gable venting requires at least two vents that are installed as high as possible in opposing wall gables, just below the peak of the roof. If your attic is unfinished, gable venting is simple, inexpensive and effective. (revised by Anthony M. From Tel Aviv, Israel on September 8, 2021) [4]
