When it comes to metal roofing, one term you may hear that can lead to confusion is ridge vents. Before you install a metal roof on your home, you should understand what a ridge vent is and what role it can play in protecting your home. Here's a look at a couple of the benefits of incorporating ridge vents into your metal roofing structure.

Encourages Traditional Air Flow

Ridge vents are placed at the edges of your roof, where the roof line meets the attic. Since hot air rises, it encourages normal air flow during the warm periods of the year. Heat rises naturally, so those vents provide a space where the warm air can exit from your attic. As the heat rises, it hits those vents and continues through the path of least resistance, which means it passes through the vents and moves outside. This can help to keep your home and your attic cooler, which may even reduce your home energy costs when it comes to climate control.

Reduces Moisture And The Associated Damage

When it comes to summer heat, it's often humid as well. When that hot air has nowhere to go, the humidity in that air can settle in your attic and eventually spread to the rest of the house. This leads to a variety of types of moisture damage. For example, when the moisture becomes trapped in the insulation, it can actually cause that insulation to deteriorate, increasing your climate control cost. In addition, when that moisture seeps into the wood and other structural elements, it can cause mold, mildew, and structural damage over time. When the wood becomes saturated, it weakens. This can threaten the strength of the home's frame, leading to serious structural concerns.

In addition to causing mold, mildew, and structural weaknesses, that moisture can also seep into the drywall and cause it to disintegrate. This can cause your interior walls to crumble, develop holes, and become generally soft. When the moisture seeps into the exterior walls as well, it can cause the exterior paint to peel or the siding to warp.

As you can see, having roof vents installed is an important consideration when you install metal roofing. The solid barrier formed by the metal can only be bypassed by openings like these that allow the warm air and moisture to pass outside of your home.
