Learn from Charlotte's trusted roofing experts. Tips on maintenance, repair, replacement, and protecting your home from the elements.
Choosing a new roof is a big deal. It is one of the most expensive things you will do for your home. In Charlotte, we have unique weather. One day it is 95 degrees and humid. The next day, we have a massive thunderstorm with wind and hail.
When you start looking for shingles, two names always come up. GAF and CertainTeed. These are the heavyweights of the roofing world. They both make great products. But which one is right for your house in the Queen City?
At Best Roofing Now, we want you to have the facts. We are a veteran-owned company. We believe in honesty and hard work. We don't use high-pressure sales. Instead, we want to teach you what makes these shingles different.
This guide will break down GAF vs. CertainTeed. We will look at how they handle Charlotte's heat. We will look at how they stand up to Lake Norman storms. By the end, you will know which one fits your needs and your budget.
GAF has been around for over 130 years. They are the largest roofing manufacturer in North America. About one out of every four homes in the U.S. has a GAF roof. They are known for being high-tech and very reliable. Most people know them for their Timberline HDZ shingles.
CertainTeed is also a legend. They started in 1904. Their name comes from their motto: "Quality made certain, Satisfaction guaranteed." They are known for making heavy, thick shingles. Their Landmark series is a favorite for many high-end homes in Charlotte neighborhoods like Myers Park and Ballantyne.
Both companies offer "architectural" shingles. These are also called "laminate" or "dimensional" shingles. They aren't flat like the old 3-tab shingles from thirty years ago. They have layers that make them look like wood shakes or slate. They are much stronger and look much better.
Before we compare the shingles, we have to talk about our local weather. Charlotte isn't like the desert or the snowy north. We have our own challenges.
First, there is the humidity. North Carolina is very humid. This leads to algae growth. Have you ever seen those ugly black streaks on a roof? That is Gloeocapsa Magma. It is a type of blue-green algae. It loves our moist air.
Second, we have the heat. Our summers are brutal. The sun beats down on your shingles all day. This can make them brittle over time.
Third, we have the storms. We get heavy rain and high winds. Sometimes we even get tropical remnants from the coast. Your shingles need to stay put when the wind gusts hit 60 or 70 miles per hour.
Lastly, there is hail. While we don't get giant hail often, it does happen. A thick shingle can help protect your home from impact damage.
GAF's flagship shingle is the Timberline HDZ. It is a very popular choice for residential roofing in Charlotte. Here is why it stands out.
GAF created something called LayerLock. Most shingles have a small area where the installer is supposed to drive the nails. If the roofer misses that small line, the shingle might blow off.
GAF made that "strike zone" much bigger. They call it the StrikeZone. It is the widest nail zone in the industry. This means our crew can install your roof faster and more accurately. When shingles are nailed perfectly, they stay on.
Because of LayerLock, GAF offers something amazing. If you use GAF shingles with four specific accessories, you get an "unlimited" wind speed warranty for 15 years. This is huge for peace of mind. Even if a massive storm hits Charlotte, your shingles are covered against blow-offs.
Remember those black streaks? GAF fights back with StainGuard Plus. They use special copper-coated granules. These granules slowly release copper over time. Copper is a natural enemy of algae.
On their premium lines like the Timberline UHDZ, GAF offers a 25 to 30-year warranty against algae. That is a long time to keep your roof looking brand new. And honestly, it makes a big difference in how your home looks from the street.
CertainTeed takes a different approach. They focus on "more is more." Their shingles are often heavier and thicker than GAF's.
A "square" of roofing is 100 square feet. A square of standard GAF shingles weighs about 220 pounds. A square of CertainTeed Landmark Pro can weigh up to 270 pounds.
Why does weight matter? A heavier shingle is harder to lift. It feels more "solid" to many homeowners. It can also handle impacts from small branches or hail a bit better. Many people think CertainTeed shingles look more "real" because the layers are thicker. This gives the roof more depth and shadow lines.
CertainTeed also uses copper granules to fight algae. They call it StreakFighter. Most of their shingles come with a 15-year algae warranty. This is very good, but it is shorter than GAF’s premium 25-year protection.
CertainTeed has a special shingle called NorthGate ClimateFlex. This shingle is made with rubberized asphalt. This makes it "bouncy." When hail hits it, the shingle absorbs the shock instead of cracking. If you live in an area of Charlotte that gets a lot of summer storms, this is a great upgrade.
Both GAF and CertainTeed offer great warranties. But there is a catch. To get the best warranty, you must use a certified contractor.
Best Roofing Now is a veteran-owned company with top certifications. We can offer you the best warranties from both brands.
If we install a full GAF system, we can offer the Golden Pledge Limited Warranty. This is the gold standard. It gives you 50 years of "non-prorated" coverage on materials. This means the value of the warranty doesn't go down as the roof gets older. It also covers our labor for 25 years. If there is a mistake in the installation, GAF pays to fix it.
CertainTeed has a similar plan called the 5-Star SureStart Plus warranty. Like GAF, it offers 50 years of non-prorated material coverage. It also includes a 25-year workmanship warranty.
In the roofing world, the warranty is only as good as the company behind it. Both GAF and CertainTeed are billion-dollar companies. They aren't going anywhere. You can trust that they will be there if you ever have a problem.
Most Charlotte homeowners want a roof that looks great but doesn't break the bank.
GAF is generally more affordable. Because the shingles are a bit lighter, they are easier to ship and handle. The LayerLock system also makes them faster to install. This usually means a lower total price for you. For many people, GAF offers the best "bang for your buck."
CertainTeed is often seen as a premium product. You are paying for that extra weight and the thicker look. If you have a high-end home and want the absolute best "curb appeal," CertainTeed might be worth the extra cost.
Think of it like choosing between a high-end Toyota and a Lexus. Both will get you where you are going safely. Both are very reliable. One is just a bit more "luxury" than the other.
According to the National Roofing Contractors Association (NRCA), the most important part of a roof is the installation. An expert quote from their technical manual states: "Even the best roofing materials will fail if they are not installed according to manufacturer instructions."
This is why we focus so much on training. Whether you choose GAF or CertainTeed, our crew follows every rule. We use the right nails. We use the right underlayment. We make sure your attic has the right ventilation.
Another industry expert from GAF once said, "A roof is a system, not just a pile of shingles." This is very true. You need the starter shingles, the ridge vents, and the leak barriers to all work together.
So, which one is better for your Charlotte home? Here is a simple way to decide.
Choose GAF if:
Choose CertainTeed if:
At Best Roofing Now, we don't play favorites. We are certified by both GAF and CertainTeed. We believe in providing options.
When we come to your home for a free inspection, we look at everything. We look at the pitch of your roof. We look at how much shade you have from trees. We check your current ventilation.
Then, we give you a recommendation based on your house. We don't use high-pressure tactics. We just give you the facts. Being veteran-owned means we value integrity. We treat your home like it was our own.
We also use drones for our inspections. This lets us see things that others might miss. We can show you high-resolution photos of your roof's condition. You can see the damage or the wear and tear for yourself.
Both GAF and CertainTeed make shingles that will last 30 to 50 years if cared for. In the Charlotte heat and humidity, either brand is a winner.
The real secret to a long-lasting roof isn't just the brand. It is the details. It is using "ice and water shield" (a sticky waterproof barrier) in the valleys where water flows. It is making sure your chimney is flashed correctly so it doesn't leak. And it is making sure your contractor stands behind their work.
Don't wait until your ceiling has a water spot to think about your roof. Most roofs in Charlotte start to show their age after 15 or 20 years. If your neighbors are getting new roofs, yours might be ready too.
