Decoding Wind Ratings: What Your Roof Shingles Can Handle

When it comes to roofing, one thing you definitely don’t want to skip over is the wind ratings of your shingles. If you live in Savannah, GA, you’re no stranger to the breezy conditions both coastal and inland. So, let’s break down how these ratings work and why they matter for your home.

What Are Wind Ratings?

Wind ratings indicate how much wind a shingle can withstand before it starts to lift, crack, or blow off. They’re typically measured in miles per hour (mph) and are assigned by various testing organizations. The most common test is the ASTM D3161 standard, which evaluates shingles' performance under wind forces.

The Basics of Shingle Ratings

• Class G: These shingles are rated for winds up to 60 mph.
• Class D: These can handle winds up to 90 mph.
• Class H: These sturdy shingles withstand winds up to 120 mph.

Now, if you’re thinking, “Well, Savannah winds aren’t that bad,” think again! The storms that roll through can pack quite a punch, especially during hurricane season. Knowing your shingles can hold up against those winds can save you from costly repairs down the road.

How Are Wind Ratings Tested?

Shingle manufacturers conduct rigorous testing. They usually use a wind tunnel to simulate strong winds and monitor how the shingles react. The tests simulate the lifting forces that occur during high winds, and only those that perform well get the higher ratings.

But remember, just because a shingle is rated for severe winds doesn’t mean it’s a one-size-fits-all solution. Proper installation plays a huge role in how those shingles perform. Even high-rated shingles can fail if they’re not installed correctly. So if you see a contractor in skinny jeans trying to sell you a roof, run the other way!
