You can be standing in Cumming during a perfectly clear afternoon, and twenty minutes later, a hail storm is moving through Lawrenceville. When you are looking at a <a href=\"https:\/\/bumbleroofing.com\/forsyth-gwinnett\/roofing-service\/roof-replacement\">roof replacement<\/a>, you are going to hear people talk about roof shingle ratings. It sounds like technical fluff, but these ratings are really just a report card for how much of a beating your house can take.<\/p>\n\n\n\n<p>At Bumble Roofing of Forsyth &amp; Gwinnett, we try to keep the explanation simple. These ratings aren&#8217;t just for show. They tell you exactly how a shingle will act when the sky turns green in the middle of a Georgia summer.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h2 class=\"wp-block-heading\"><strong>The Quick Breakdown: Class 3 vs Class 4 Shingles<\/strong><\/h2>\n\n\n\n<p><strong><br><\/strong>People often ask what the actual difference is when you look at the testing. The industry uses something called the UL 2218 test, which basically involves dropping heavy steel balls on shingles to see if they break.<\/p>\n\n\n\n<p>If you want the &#8220;cliff notes&#8221; version of how these compare, here is the gist of it:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Class 3 Shingles<\/strong>: These are tested against a 1.75-inch steel ball. Most pros consider this the standard for a good, durable roof. It handles the typical Georgia storms and small hail without much of a problem. It is a great balance if you want protection without a massive price jump.<\/li>\n\n\n\n<li><strong>Class 4 Shingles<\/strong>: This is the highest rating you can get. They drop a 2-inch steel ball on these. While a quarter-inch difference doesn&#8217;t sound like much, the impact force is significantly higher. If you live in an area of Gwinnett that seems to get hit with hail every single spring, this is usually the best way to go.<\/li>\n\n\n\n<li><strong>The Big Difference<\/strong>: Class 4 shingles are designed not to crack or rupture even under heavy impact. This keeps the asphalt underneath protected, which is what actually keeps your house dry.<\/li>\n<\/ul>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h2 class=\"wp-block-heading\"><strong>Why Shingle Impact Ratings Matter for Your Attic<\/strong><\/h2>\n\n\n\n<p><strong><br><\/strong>It is easy to think that <a href=\"https:\/\/bumbleroofing.com\/forsyth-gwinnett\/roofing-type\/shingle-roofing\">shingle impact ratings<\/a> are only about stopping a leak right now. But it is actually about the granules. When hail hits a cheap shingle, it knocks those little rocks off. Once the granules are gone, the Georgia sun starts to bake the asphalt. That makes the shingle brittle, and it will eventually fail way sooner than it should.<\/p>\n\n\n\n<p>By picking a higher rating, you are making sure your roof stays flexible. It is a long-term play. In Forsyth and Gwinnett, we see roofs that look ten years older than they are simply because they didn&#8217;t have the right impact resistance to deal with a couple of bad seasons.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h2 class=\"wp-block-heading\"><strong>Don&#8217;t Ignore the Wind<\/strong><\/h2>\n\n\n\n<p>Impact is a big deal, but the wind in North Georgia is just as much of a threat. We get some serious gusts during those afternoon thunderstorms. Most shingles today have a roof shingles wind rating that handles speeds between 110 and 130 mph.<\/p>\n\n\n\n<p>But here is the catch. A <a href=\"https:\/\/bumbleroofing.com\/forsyth-gwinnett\/roofing-type\/shingle-roofing\">high shingle wind rating<\/a> is only as good as the guy with the nail gun. If the roof installation isn&#8217;t done with the right nailing pattern, those shingles are going to peel right off during a storm. We make sure the fastening is exactly where the manufacturer says it should be. Otherwise, the rating is just a number on a package.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h2 class=\"wp-block-heading\"><strong>The Financial Side of Better Shingles<\/strong><\/h2>\n\n\n\n<p><strong><br><\/strong>There is a real-world benefit to picking a better shingle that shows up in your bank account. Many insurance companies in Georgia give you a break on your premiums if you have &#8220;impact-resistant&#8221; roofing. Moving to Class 4 shingles can sometimes drop your annual bill by 10% to 25%.<\/p>\n\n\n\n<p>And if you ever sell your house in Cumming or Lawrenceville, having a high-rated roof is a major selling point. It tells a buyer the home is solid. Plus, it keeps your out-of-pocket costs down because you aren&#8217;t filing an insurance claim for every minor hail event that comes through the neighborhood.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h2 class=\"wp-block-heading\"><strong>Getting it Done With Bumble Roofing<\/strong><\/h2>\n\n\n\n<p><strong><br><\/strong>Picking the right materials is a lot easier when you have a local team that actually knows the area.
