The Advantages of a Metal Roof

Metal roofing has been used to cover barns, buildings, and homes across the U.S. since the 1700s. Today’s metal roof has come a long way from the tin roofs of old though, and metal roofing is now more popular than ever. Standing seam metal roofs are now available in various styles, designs, and colors, and the substrates used are much stronger and more resilient, offering even better long-term performance.

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.

Metal Roofing and Ventilation

Like many other types of roofing, metal roofing relies on what’s called static ventilation. What this means is that the roof is designed to promote natural airflow, rather than relying on fans or other forced methods to create air movement. Static ventilation takes advantage of the effects of rising hot air to help move heat and moisture out of the attic and through the upper vented portion of the roof.

Why Good Ventilation Is Important to Any Roof

Proper attic ventilation is essential to help your roof maintain a cooler temperature. Regardless of the material used to cover your roof, it’s a good idea to let your roof breathe by taking advantage of a well-designed ventilation plan. This includes making sure there’s a proper balance of intake vents for fresh air to enter from below, along with exhaust vents so hot air can exit from the top.

• Energy efficiency strategy

Simply put, the hotter your roof gets on a sunny day, then the hotter your attic will get. As your attic heats up, so too will your home or business living space. The result is that your air conditioning system will have to work harder, ultimately driving up your energy usage and costs. One advantage to choosing a metal roof is the fact that metal’s reflectivity sends away more of the sun’s radiation than other materials. Even so, a metal roof can still get relatively hot! That’s why it’s important to also have a good roof ventilation system in place to help move heat out of your attic.

• Condensation issues

Home living spaces can generate a significant amount of moisture through activities like bathing, showering, cooking, and doing laundry. Where does all that moisture go? Much of it tends to migrate upwards. Once this moisture reaches the attic, it can condense on cooler surfaces. This collected moisture can help breed mold and mildew, and can eventually contribute to structural damage. A well-vented attic will help to keep your insulation dry (and thus more effective), and will also help to keep the threats of condensation at bay.

• Avoiding ice dams in the winter

If you live someplace that tends to get more than its share of winter weather, then ice dams are another roof concern. Ice dams happen when warm air from the interior reaches the roof deck, causing accumulated frozen precipitation to melt. This liquid runs down the roof and refreezes on the roof overhangs, creating potentially dangerous and damaging ice dams to form. Having the right roof ventilation can help keep attic temperatures more even, thus helping to prevent the formation of ice dams in the first place.


Ridge Vents for Metal Roofs

Ridge vents are a very effective way to promote proper attic ventilation and are commonly used on shingle roofs and roofs covered with other materials. Ridge vents are becoming more popular for metal roofs, as well. These vents are installed across the entire length of the ridgeline. When coupled with soffit vents placed on the underside of the roof, this system offers a great means of introducing fresh air and conducting warm, moist air up and out of the attic.
