How Metal Roofing Handles Wind, Rain, and Snow

When it comes to protecting your home against the unpredictable weather of Western Washington, metal roofing systems stand as one of the most durable and reliable options available. From heavy rainfall and high winds to snow and hail storms, metal roofing is designed to endure it all. But how exactly does metal roofing handle these harsh conditions? Let’s explore how metal roofing offers superior protection, energy efficiency, and longevity while answering some of the most common concerns homeowners have. 

Why It Excels in Harsh Weather

Here in Western Washington, our weather’s mood swings aren’t exactly gentle with roofs. The diverse weather patterns make choosing roofing materials that can withstand the elements year-round very important. One of the best options around, metal roofing, is renowned for its wind resistance, efficient water-shedding properties, and ability to manage snow loads. Plus, these roofs are impact resistant, helping to protect your home during severe weather like hail storms.

Metal Roofing and Wind Resistance

Metal roofing systems are engineered to resist high winds, making them ideal for areas prone to storms and strong gusts.

Design Features That Combat Wind Uplifts

  • Standing seam metal roofs use interlocking panels, which offer better wind resistance by reducing points of vulnerability.
  • Secure fastening systems ensure panels remain attached during extreme wind speeds.
  • Aerodynamic profiles minimize wind uplifts, helping the roof withstand gusts up to 140 mph, depending on the roofing system.

How Metal Roofs Compare to Asphalt Shingles in High Winds

  • Asphalt roofing is more susceptible to wind damage, especially when they age and begin to deteriorate.
  • Metal roofs maintain their integrity even after years of exposure, reducing the risk of costly repairs after storms.

Performance in Heavy Rainfall

Water Shedding Capabilities: Less Leakage

The non-porous material of the metal roofing allows water to run off quickly and reduces the risk of leaks. Plus, most metal roofs’ standing seam design can further improve water flow by eliminating gaps where the water could seep through. 

Do Metal Roofs Leak More Than Shingles? 

The idea that metal roofs leak more than shingles is a common myth, but it’s just that–a myth. In reality, with the help of a watertight design, proper installation by a professional, and quality sealant, metal roofs are often just as water tight as shingle roofs. 

Snow Load Management

Snow may not be as frequent in Western Washington as rain, but when it falls, it’s essential that your roof can handle the weight and removal.

Metal Roof Snow Shedding Properties

  • The smooth surface of metal allows snow to slide off easily, preventing dangerous build-ups.
  • This natural shedding reduces wear and tear on the structure by minimizing prolonged snow loads.

Using Snow Guards for Safety and Efficiency

  • Snow guards help control snow as it slides off, preventing sudden dumps that could damage property or injure people below.
  • Strategically placed snow guards balance efficient snow removal while maintaining safety.

Durability During Hail Storms

Hail can cause significant damage to roofs, but metal stands up to the challenge.

Impact Resistance of Metal Roofing

High-quality metal roofs are impact resistant, reducing the chance of dents and structural damage during a hail storm. Plus, thicker metal gauges and textured finishes help minimize cosmetic damage. 

Insurance Companies and Hail-Resistant Roofing

Some insurance companies may offer lower premiums for homes with metal roofs due to their durability and resistance to hail-related claims. 

Common Concerns About Metal Roofing

Initial Cost: Metal roofs generally have a higher upfront cost compared to asphalt shingles. However, the investment pays off in the long run due to durability and energy savings.

Thermal Expansion: Metal can expand and contract with temperature changes, which may lead to issues over time if not properly installed. Modern installation techniques, like standing seam designs, help manage this movement.

Noise Concerns: Without proper insulation, metal roofs can be noisier during rain or hailstorms. Adding underlayment or insulation helps reduce this issue.

Potential for Dents: While metal roofs are impact resistant, severe hailstorms can sometimes cause dents, especially in softer metals like aluminum. Choosing thicker gauges and textured finishes can minimize this risk.

Energy Efficiency and Long-Term Benefits

Metal roofing is inherently energy efficient, reflecting sunlight and reducing heat absorption during the summer months. These reflective properties help lower cooling costs, making it a smart choice for your budget and the environment.
