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.
The Battle of the Brands: Who Are They?
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.
Durability and Weight: Why Mass Matters
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.
CertainTeed: The Heavyweight Champ
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: The High-Tech Contender
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.
Wind Resistance: Surviving the NC Storms
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!
- GAF’s Secret Weapon: GAF’s Timberline HDZ shingles feature the "StrikeZone." This is a huge nailing area that makes it almost impossible for a roofer to miss the right spot. When nailed correctly, GAF offers a WindProven™ Limited Wind Warranty. This is unique because it has no maximum wind speed limit when installed with the right GAF accessories.
- CertainTeed’s Approach: CertainTeed relies on its weight and high-quality adhesive strips. Their shingles are very hard to lift once the sun bakes that adhesive down. They also meet the 130 mph standard, provided they are installed with the correct number of nails.
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.
Algae and Humidity: The "Black Streak" Problem
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.
- GAF StainGuard Plus™: GAF recently upgraded their algae protection. Their high-end shingles now come with a 25 or even 30-year algae warranty. This is a big deal in the South.
- CertainTeed StreakFighter®: CertainTeed has a long history of excellent algae resistance. Most of their shingles come with a 10 to 15-year warranty against those black streaks.
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.
Aesthetics and Curb Appeal
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.
Warranty: Protecting Your Investment
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.
The Standard Warranty
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.
The Enhanced Warranty (The Best Way)
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.
- GAF Golden Pledge®: This is the gold standard. It covers the entire roofing system. It gives you 50 years of non-prorated protection on materials. Most importantly, it covers workmanship for up to 25 years. If the roof leaks because of a mistake we made, GAF pays to fix it.
- CertainTeed SureStart™ PLUS: CertainTeed has a similar program. Their 5-Star warranty also offers 50 years of non-prorated coverage and 25 years on workmanship.
"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)
Cost vs. Value: What Is the ROI?
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.
Sustainability and Innovation
At Best Roofing Now, we love technology. Both brands are working hard to be more "green."
- GAF has shingles that can actually reflect sunlight to keep your attic cooler. This can save you money on your Duke Energy bill! They also have a program to recycle old shingles so they don't end up in a landfill.
- CertainTeed focuses on sustainable manufacturing. Many of their shingles are made using recycled materials. They also offer "cool" shingle options that meet LEED requirements for energy efficiency.
