Choosing a new roof is a big deal. It is one of the most important things you will do for your home. Here in Charlotte and Lake Norman, our roofs take a beating. We have hot, humid summers. We get heavy rain and the occasional crazy wind storm. If you are looking at shingles, you have probably heard two names over and over: GAF and CertainTeed.
They are the "heavyweights" of the roofing world. Think of them like Ford vs. Chevrolet or Duke vs. UNC. Both have huge fan bases. Both make great products. But which one is the right fit for your specific house?
At Best Roofing Now, we don't just "sell" you a roof. We are consultants. We want you to understand what you are buying. We are a veteran-owned business, and we take craftsmanship seriously. Whether you are in Huntersville, Mooresville, or right in the heart of Charlotte, this guide will help you decide between GAF and CertainTeed.
Before we dive into the technical stuff, let’s look at the players.
GAF is the largest roofing manufacturer in North America. They have been around since 1886. They are known for their Timberline series. In fact, more people in the U.S. choose GAF Timberline shingles than any other brand. They are the "people’s choice."
CertainTeed is also a giant. They started in 1904. They focus heavily on quality and weight. Their shingles are often thicker and heavier than the competition. They position themselves as the "premium" choice for homeowners who want the most robust materials.
Both brands have deep roots. Both offer "lifetime" warranties. But the way they build their shingles is a little different.
In the roofing world, weight usually means more protection. A heavier shingle has more asphalt. More asphalt generally means it can stand up to the sun and rain longer.
If we put a square (100 square feet) of CertainTeed Landmark shingles on a scale, it would weigh about 230 to 250 pounds. That is a lot of material! Because they use more asphalt and a thicker fiberglass mat, these shingles feel very solid. This extra mass helps the shingle stay flat and resist curling over time.
GAF shingles, like the Timberline HDZ, are a bit lighter. They usually weigh around 220 to 230 pounds per square. Now, don't think "lighter" means "weaker." GAF uses a different technology. They focus on how the shingles lock together. Their LayerLock™ technology creates a mechanical bond between the shingles. It is like shingles that "hold hands" to stay on your roof.
Why this matters for your Charlotte home:
If your home is in an area with lots of mature trees (like Myers Park), you might want the extra thickness of CertainTeed to handle falling small branches. If you want a shingle that is designed for speed and precision locking, GAF is a fantastic choice.
We don't get hurricanes every day, but we do get high winds. When a summer storm rolls through Lake Norman, you want to know your shingles will stay put.
Both GAF and CertainTeed offer shingles rated for 130 mph winds. That is equivalent to a Category 3 hurricane!
The Verdict on Wind:
If you are worried about extreme gusts, GAF’s "no limit" wind warranty is hard to beat. But honestly, if either roof is installed by a pro like Best Roofing Now, it’s going to stay on your house.
Have you ever seen those ugly black streaks on a roof? That isn't dirt. It is actually a type of algae called Gloeocapsa magma. It loves the heat and humidity of North Carolina.
Both brands fight this by putting copper granules into the shingles. Copper is toxic to algae.
Why it matters:
A roof can be perfectly functional but look "old" because of algae. If you want your home to stay looking brand new for decades, pay close attention to the algae warranty.
Your roof is about 40% of what people see when they look at your house. You want it to look good!
CertainTeed is often praised for its "architectural" look. Their shingles have a lot of depth and shadow lines. They look very thick and dimensional. If you have a high-end home in a neighborhood like The Sanctuary or The Peninsula, CertainTeed gives that "luxury" feel.
GAF has some of the most popular colors in the country. Their shingles look great on almost any style of home. They have a clean, modern look that appeals to many homeowners.
This is where things get a little technical, but it is super important. A "Lifetime Warranty" doesn't always mean what you think it does.
If you just buy the shingles and have some guy install them, you usually only get a "material" warranty. If the shingle fails, the manufacturer might give you new shingles, but they won't pay for the labor to put them on.
To get the real protection, you need to use a certified contractor. We are GAF Certified, which means we can offer the best warranties in the business.
"The most important part of a roof isn't the brand of shingle; it's the quality of the installation and the strength of the warranty behind it." : Industry Expert from the National Roofing Contractors Association (NRCA)
Let's talk money. We know that a new roof is a big investment.
Generally, GAF is more budget-friendly. Because they are so large and their shingles are a bit lighter, they are often more cost-effective to ship and install. You get a world-class roof without the highest price tag.
CertainTeed is usually the more expensive option. You are paying for that extra weight and asphalt. Expect to pay roughly 10% to 20% more for a CertainTeed Landmark roof compared to a GAF Timberline roof.
Is it worth the extra cost?
If you plan to live in your home for 30 years, that extra weight might be worth it. If you are looking for the best "bang for your buck" while still getting a high-quality product, GAF is usually the winner.
At Best Roofing Now, we love technology. Both brands are working hard to be more "green."
We are a veteran-owned and operated company. That means we value integrity. We don't believe in high-pressure sales. We believe in education.
When we come out to your home for a free inspection, we look at more than just the shingles. We look at your attic ventilation. We check your gutters. We look at the flashings (the metal bits that stop leaks).
We choose to work with these brands because they stand behind their products. Whether we install GAF or CertainTeed, we know we are giving you a roof that will protect your family for a lifetime.

So, who wins the heavyweight fight?
Choose GAF if:
Choose CertainTeed if:
At the end of the day, a roof is only as good as the hands that install it. You can buy the most expensive CertainTeed shingle in the world, but if it is installed poorly, it will leak.
