Metal Roof Snow and Wind Load-Bearing Capabilities—Explained

Considering the snow and wind load-bearing capabilities is critical when choosing a new metal roof for your home. This is especially important if your home is in a harsh weather zone, prone to heavy rain and hailstorm.

Metal roofs are known for their exceptional durability and weather damage prevention. They can withstand North Carolina’s hurricane seasons and protect your property and its occupants. So let’s dig deeper and learn more about metal roofs and their snow/wind loads.

Load-Bearing Capacity in Metal Roofs

The load-bearing properties of a metal roof are determined by several factors, including its alloy type, panel style, foundation, and slope. Moreover, certain areas in North Carolina require homeowners to opt for a higher load-bearing roof due to regional weather events. Snow and wind loads are the two most components affecting a metal roof’s structural performance and are discussed below:

1. Snow Load of a Metal Roof

A metal roof’s snow load is referred to as the amount of snow that can sit on its surface per unit. Steeper metal roofs have higher chances of bearing snow load as they don’t allow the snow to sit for longer periods. Your best bet to getting a new metal roof’s snow load right is to consult an expert metal roofing contractor.

Our metal roof installation team can help you by providing tailored products according to your regional snowfall calculation and home’s architectural style.

2. Wind Load of a Metal Roof

The next thing you should pay attention to in a metal roof is wind load. It’s referred to as the load or pressure exerted by wind and is determined by several factors, such as:

Wind lift resistance
Wind zone calculations
Ridge and edges lift resistance
