GAF, Owens Corning, and CertainTeed dominate the NJ market. All three are solid products. The real variable is installation quality — which accounts for 70% of a roof's long-term performance. This guide explains exactly what separates each brand, what contractors won't tell you, and how to make a genuinely informed decision.
Every shingle brand says they're the best. Every contractor says they use "premium materials." Online comparisons are written by content agencies that have never touched a roof. Here's what actually matters — from someone who spent two decades watching which shingles hold up, which ones blow off in storms, and which ones contractors recommend because of incentives, not performance.

The 3 Tiers of Roofing Shingles
Before comparing individual brands, understand the market structure. Roofing shingles fall into three practical tiers — and knowing where each brand sits tells you a lot about who's recommending them and why.
- BP is primarily Canadian/northern US. PABCO is West Coast. Malarkey is Pacific Northwest.
- If you're in New Jersey, you likely won't see these brands quoted — they don't have distribution here.
- Not bad products — just not relevant to most NJ homeowners.
- If a contractor quotes you one of these in NJ, ask why. It may mean they got a deal on leftover inventory.
- IKO: Affordable, decent warranty on paper. Thinner mat, lighter weight, more prone to granule loss in years 1–5. Popular with budget contractors.
- TAMKO: Similar tier. Adequate for mild climates. In NJ with nor'easters, freeze-thaw, and hail — not the strongest choice.
- Atlas: Actually makes a solid shingle (Pinnacle Pristine with Scotchgard). Underrated but limited contractor training compared to GAF or OC.
- Dominate 90%+ of the US market
- The brands you'll see in 90%+ of NJ roofing estimates
- Each has genuine strengths and real weaknesses that most comparisons skip
- The rest of this guide focuses entirely on these three
Mid-tier brands are often pushed because contractors get better pricing margins on them — not because they're the best product for your roof. A contractor can buy IKO for significantly less than GAF and charge you a similar price, keeping the margin difference. Ask what THEY would put on their own house.
Deep Dive: GAF
GAF is the largest shingle manufacturer in North America. They own the market through brand dominance, contractor certification programs, and aggressive marketing. When a homeowner says "I've heard of GAF," that's by design — the brand spends heavily to be the name people recognize.
The Products
- Timberline HDZ: Their flagship architectural shingle. Features a "StrikeZone" nailing area clearly marked on every shingle. Solid product, reasonable price, the most commonly installed shingle in NJ.
- Timberline AS II: Armed with StainGuard Plus algae resistance. Good for NJ's humid summers — prevents those black streaking patterns you see on older roofs.
- Camelot / Grand Sequoia: Premium designer lines. Visually striking — mimic the look of natural wood shake or slate. More expensive, but genuinely beautiful if the budget allows.
What's Good
- Extremely consistent quality — you know what you're getting batch to batch
- Largest contractor certification network in the country (Master Elite) — means more trained installers know this product
- Nailing zone is clearly marked and forgiving — fewer installation errors even from less experienced crews
- Warranty programs are the most aggressive in the industry — GAF actually pays claims
- Widely available at every NJ distributor — no supply chain uncertainty
What They Don't Tell You
- The "lifetime warranty" is prorated after year 10 — not full coverage for life
- Master Elite certification is partly a marketing play — contractors pay for it and get leads in return. Some excellent roofers aren't certified because they won't pay the fee.
- The shingle itself is mid-weight — not the thickest option in this price range
- High brand awareness drives up demand, which sometimes drives up price in competitive markets
Deep Dive: Owens Corning
Owens Corning's Duration series is a genuinely excellent product. But it has one defining characteristic that separates it from every other brand — and it can either be the shingle's greatest strength or its biggest vulnerability, depending entirely on who installs it.
The Products
- Duration: Their flagship. TruDefinition color depth, SureNail Technology — the fabric reinforcement strip that defines this shingle. When installed correctly, this is arguably the best standard architectural shingle available.
- Duration STORM: Class 4 impact resistant. May qualify NJ homeowners for insurance premium discounts of 15–25%. If you're in Mercer County or anywhere that sees regular hail, this product is worth a serious look.
- Oakridge: Entry-level architectural. Thinner than Duration but budget-friendly. Good for accessory structures or lower-pitch applications where you're cost-conscious.
What's Good
- SureNail Technology — fabric reinforcement strip in the nailing zone provides superior holding power when installed correctly
- Duration STORM is genuinely best-in-class for impact resistance among architectural shingles
- Color depth and curb appeal is arguably stronger than GAF at comparable price points
- Excellent in high-wind regions — NJ coast and shore areas benefit significantly
- Strong brand recognition thanks to the Pink Panther marketing campaign
What They Don't Tell You
- The SureNail fabric strip requires nails driven to an exact depth — overdriven nails punch THROUGH the fabric and lose holding power entirely
- Many crews don't adjust nail gun pressure per OC spec — this is the #1 Duration failure mode
- Warranty claims for blown-off Duration shingles often get denied because overdriving is classified as installer error
- Requires more experienced installers than GAF — the skill gap has real consequences
The SureNail fabric strip is ALSO the biggest risk factor. Here's why: The fabric strip requires nails driven to a very specific depth. If the nail is overdriven (too deep), it punches through the fabric strip and loses almost all holding power. The shingle looks installed but is essentially floating.
This matters because nail guns set to the wrong pressure overdrive nails constantly. Many crews don't adjust their guns per manufacturer spec. In storm damage inspections, OC Duration shingles that blew off almost always show overdriven nails. With GAF, an overdriven nail is still partially held by the asphalt mat. With OC, an overdriven nail through the fabric = zero wind resistance.
What contractors won't tell you: If your contractor's crew isn't specifically trained on OC Duration installation and doesn't adjust nail gun pressure per spec, the SureNail strip becomes a liability, not an advantage. The gap between a well-installed Duration and a poorly-installed Duration is wider than with any other brand.
Deep Dive: CertainTeed
CertainTeed (owned by Saint-Gobain, the French building materials giant) doesn't market to homeowners the way GAF and OC do. They market to contractors. And contractors respect them — often more than either of the more recognized brands. There's a reason experienced roofers reach for CertainTeed when they're doing their own roofs.
The Products
- Landmark: Their bread-and-butter architectural shingle. Thick, heavy, reliable. The workhorse product — consistently well-reviewed by installation crews for how it lays and holds.
- Landmark Pro: Slightly upgraded. MaxDef color technology delivers richer, more consistent color that holds over time. A step up in visual quality without a dramatic price jump.
- NorthGate: SBS-modified asphalt shingle — the asphalt compound stays flexible in cold temperatures instead of becoming brittle. Excellent for NJ's freeze-thaw cycles. Also impact-resistant. One of the best-engineered shingles for New Jersey's climate specifically.
What's Good
- Landmark is one of the heaviest, thickest architectural shingles in its price range — genuine mass that translates to durability
- SBS-modified products (NorthGate) stay flexible in cold — critical for NJ's 50+ freeze-thaw cycles per winter
- NorthGate qualifies for impact-resistant rating, potentially reducing insurance premiums
- CertainTeed's warranty is straightforward with fewer gotchas in the fine print
- Contractor-respected: experienced roofers prefer CT because it installs cleanly and holds up without fuss
What They Don't Tell You
- Lower brand recognition means homeowners sometimes assume it's a lesser product — it's not
- Fewer certified contractor programs than GAF, so warranty coverage can be harder to claim in some cases
- Not as universally stocked as GAF at every NJ distributor — some suppliers carry limited CT lines
- The lack of aggressive marketing means you'll need to do more research to feel confident in the choice
Good sign: If your contractor recommends CertainTeed Landmark and you've never heard of it — that's actually a positive signal. It often means they're recommending based on product quality and performance, not because of a brand marketing relationship or rebate incentive.
The Truths Nobody
Will Say Out Loud
This is the part of the article that would make shingle sales reps uncomfortable. These are the things that come from watching the industry from the distribution side for over two decades — not from a product brochure.
"The industry sells homeowners on brand names because brand names are easy to explain. The harder truth — that a shingle is only as good as the crew nailing it down — doesn't fit on a billboard."
— Best Crew Construction, 20+ years roofing distributionHow Shingles Actually Fail
In Plain English
Understanding failure modes takes the guesswork out of every contractor conversation you'll ever have. These aren't technical obscurities — they're the mechanisms behind the majority of premature roof failures in New Jersey.
Nail Zones and Why They Matter
Every shingle has a specific area where nails are supposed to go. This "nail zone" or "nail line" is where the shingle overlaps the one below it — meaning each nail holds two shingles in place simultaneously. If the nail goes above or below this zone, it only holds one shingle (or none at all). This is the single most common installation error — invisible from the ground until a storm reveals it.
The high-nail problem: Nails placed too high (above the nailing zone) only hold one shingle instead of two. The shingle looks perfect from the street. The first 60 mph gust peels them back and you see clean rectangles of bare underlayment. This happens on new roofs regularly — and it's always an installation failure, not a product failure.
Overdriven Nails — The Silent Failure
A nail gun set too high will drive the nail too deep — it punches through the shingle mat instead of sitting flush with the surface. The shingle looks perfectly installed from above. But the holding power is nearly zero. This is invisible until a storm rips the shingle off and you see a clean hole where the nail tore through the thin cap.
With GAF, an overdriven nail is still partially anchored in the asphalt mat below the surface — it has some holding power, even if reduced. With Owens Corning Duration and its SureNail fabric strip: an overdriven nail goes completely through the reinforcement strip and into empty space beneath it. The strip's holding power drops to essentially zero. This is not a product defect — it's why OC requires more nail gun precision than any other brand on the market.
Blow-Off vs. Blow-Through
When shingles blow off in a storm, the first thing an inspector looks at is the nail pattern. If nails are overdriven, high-nailed (above the zone), or insufficient in quantity (4 nails instead of 6 in a high-wind zone) — that's an installation failure, not a product failure. Insurance adjusters and manufacturers both use this distinction when evaluating warranty claims. Understand it before your next nor'easter.

Side-by-Side
Comparison
The most honest head-to-head comparison of the three brands you'll actually see in a New Jersey roofing estimate. Every cell is based on real-world performance observation, not manufacturer marketing.
| GAF Timberline HDZ | Owens Corning Duration | CertainTeed Landmark | |
|---|---|---|---|
| Ease of Install | ★★★★★ Easiest — forgiving nail zone. Most crews install this correctly without extra training. |
★★★☆☆ Requires precision. Fabric strip demands correct nail depth — wrong depth defeats the technology. |
★★★★☆ Straightforward. Lays cleanly and holds well. Experienced crews consistently rate it highly. |
| Brand Recognition | ★★★★★ Highest — the most marketed brand. Homeowners ask for it by name. |
★★★★☆ Strong — "Pink Panther" brand awareness campaign is well-recognized. |
★★★☆☆ Lower with homeowners. High with contractors. Contractors trust it; homeowners haven't heard of it. |
| Weight / Thickness | Medium — consistent, adequate mass | Medium-Heavy — heavier than GAF in the HDZ line | Heavy — one of the thickest architectural shingles in its class |
| Wind Rating | 130 mph standard | 130 mph standard 150 mph with SureNail + 6-nail pattern |
110–130 mph depending on product line |
| Impact Resistance | Standard (Class 1–2) | STORM line = Class 4 Best-in-class for hail resistance |
NorthGate = Class 4 SBS-modified, stays flexible in cold |
| NJ Climate Fit | Good — solid all-around performer in NJ conditions | Excellent (with proper install) — high-wind coast and hail performance is best-in-class | Excellent — SBS-modified NorthGate engineered for freeze-thaw |
| Warranty Quality | Strong — aggressive claims support. GAF actually honors claims at a higher rate than competitors. | Good — but fabric strip installation failures are often classified as installer error and denied | Straightforward — fewer gotchas in the fine print, but fewer certified contractor programs |
| Contractor Incentives | Highest — Master Elite program drives significant volume. Recommendations may be incentive-influenced. | Moderate — preferred contractor programs exist but less pervasive than GAF | Low — largely chosen on merit. Less incentive distortion in recommendations. |
| Risk Factor | Low — very forgiving to install and maintain | Medium — installation-sensitive. High upside, real downside risk with wrong crew | Low — consistent performance, few installation surprises |
| Best For | "Set it and forget it" — the safe default. Good for homeowners who want confidence without overthinking it. | High-wind and hail zones with a crew specifically trained on OC installation requirements | Homeowners who trust their contractor's recommendation. Experienced crews who value product quality over brand marketing. |
| Our Honest Take | "Can't go wrong. The Toyota Camry of shingles." | "Best shingle on the market IF installed perfectly." | "The one experienced contractors put on their own house." |
What the Contractor Says
vs. What It Usually Means
These are real contractor statements — the kind you'll hear in 8 out of 10 roofing estimates. Here's the translation layer that two decades of distribution experience provides.
Quick Checklist Before
Choosing Your Shingle
Bring these questions to every roofing estimate. Honest contractors will have clear answers. Evasive answers tell you as much as direct ones.
- Ask which specific product line — not just the brand. "GAF" is not enough. Ask: "Is this the Timberline HDZ or the Timberline CS? What's the weight class?"
- Ask about volume incentives or certifications. "Do you have a certified contractor agreement or volume rebate with this brand?" Honest contractors will answer directly.
- Confirm the nail pattern. In NJ high-wind zones, 6-nail installation should be standard on every architectural shingle. 4-nail is the bare minimum — not appropriate for nor'easter country.
- Ask about ice & water shield coverage. Ask: "Will ice & water cover full field or just valleys and eaves?" Full-field application is better protection for NJ's freeze-thaw cycling. At minimum, it should cover the first 6 feet from the eave edge.
- Review the warranty details in writing. How many years at full (non-prorated) coverage? Is labor covered? If so, for how long? Does the warranty transfer if you sell the house?
- Ask: "What would you put on YOUR house?" Watch the hesitation. Watch if they pivot back to a brand name without elaborating. The quality of this answer tells you everything.
How We Choose Shingles
At Best Crew
It's not what you'd expect from a roofing company. We don't have a wall of plaques from GAF. We don't have an OC incentive agreement. We don't push one product because of the margin we make on it.
"We install GAF, Owens Corning, and CertainTeed. We're comfortable with all three. What we're NOT comfortable with is recommending one brand over another just because it makes us more money. Every recommendation we make is based on your specific roof — not our certification relationships."
We're based at 118 McClellan Ave, Hamilton, NJ 08610. We serve Mercer County, Middlesex County, and surrounding areas. NJ HIC #13VH12304900. We are the installation crew — not a company that subcontracts to one.

Common Questions
Answered Directly
No hedging, no marketing language. These are the questions we hear most often — answered the same way we'd answer them in person.
GAF, Owens Corning, and CertainTeed are the three dominant brands in the US market, each with genuine strengths. GAF Timberline HDZ is the most forgiving to install correctly. Owens Corning Duration is arguably the best-performing shingle when installed to specification. CertainTeed Landmark is one of the heaviest and most respected among experienced contractors. The honest answer is that the brand matters less than the installation quality — a well-installed mid-tier shingle will outlast a poorly installed premium product in every real-world scenario.
At the architectural tier (the most common), the cost difference between mid-range and premium shingles is often $500–$1,200 on a typical NJ roof. The performance gap is real but smaller than marketing suggests. The bigger cost variable is labor quality — installation errors that compromise a $120-per-square shingle are far more costly than upgrading from a $90 to a $120 product. Spend on a better crew before spending on a more expensive shingle. Class 4 impact-resistant upgrades (OC Duration STORM, CertainTeed NorthGate) can be genuinely worth it if they qualify you for insurance discounts in NJ — do the math on the 5-year savings before deciding.
Longevity depends more on installation quality, roof ventilation, and climate than on brand name. That said, SBS-modified shingles (like CertainTeed NorthGate) are engineered to flex in freeze-thaw cycles rather than crack — which matters significantly for New Jersey's 50+ cycles per winter. Impact-resistant Class 4 shingles like Owens Corning Duration STORM hold up better to hail damage. Properly installed architectural shingles from any of the Big 3, with good ventilation and ice & water shield, should realistically last 25–35 years in NJ. Roof systems that fail early almost always have installation deficiencies, not product defects.
Neither is objectively superior — they excel in different contexts. GAF Timberline HDZ is easier to install correctly because its StrikeZone nailing area is visible, wide, and forgiving, making it the safer choice when you're uncertain about your crew's precision. Owens Corning Duration is a technically excellent shingle with superior wind resistance when installed properly — but the SureNail fabric reinforcement strip requires precise nail depth. An overdriven nail punches through the strip and loses holding power entirely. With GAF, an overdriven nail still has partial asphalt mat contact. The best shingle is the one your specific crew installs correctly, every time.
Yes — CertainTeed Landmark is one of the heaviest, thickest architectural shingles in its price range, and it's widely respected among experienced installation crews. The brand has lower homeowner recognition than GAF or OC, which sometimes causes people to question whether it's a lesser product. It's not. CertainTeed's NorthGate line uses SBS-modified asphalt that stays flexible in cold weather — a specific engineering advantage for New Jersey winters. Many seasoned contractors prefer CertainTeed on their own homes precisely because they know the product quality is not driven by marketing relationships.
New Jersey presents four distinct challenges: freeze-thaw cycling (50+ cycles per winter in Central NJ), nor'easters with 60-80 mph gusts, summer humidity that promotes algae growth, and 2-3 hail events annually in Mercer County. For NJ: SBS-modified shingles (CertainTeed NorthGate) handle freeze-thaw best by staying flexible in cold. Class 4 impact-resistant shingles (OC Duration STORM, CertainTeed NorthGate) protect against hail and may earn insurance discounts of 15-25%. Algae-resistant shingles (GAF TimberLine AS II with StainGuard, OC Duration with ArmorGuard) prevent the black streaking pattern you see on many NJ roofs after 5-10 years. Six-nail installation should be standard in NJ, not optional.
Yes — and more commonly than most homeowners realize. Roofing manufacturers run certification programs, volume rebates, and preferred pricing tiers. A contractor installing 200+ squares of GAF per quarter may earn rebates, discounted pricing, and customer leads in return. This isn't necessarily unethical — it's standard industry practice. But it means a brand recommendation may not be purely about what's best for your roof. Always ask: "Why do you recommend this specific brand?" and "Do you have a volume agreement or certification with them?" Honest contractors will answer directly. The answer itself is less important than whether they can give you one.
3-tab shingles are a single layer of asphalt, flat, and lightweight — the standard through the 1990s but now largely obsolete for residential roofing. Architectural (also called dimensional or laminate) shingles are two layers of asphalt bonded together, creating a dimensional shadow line that mimics the look of natural slate or wood shake. Architectural shingles are heavier, hold up better to wind and hail, carry better warranties, and look significantly better on a home. In New Jersey, 3-tab shingles are rarely installed on new residential roofs — architectural is the baseline standard for any quality installation. If a contractor is quoting you 3-tab in 2026, ask why.
Significantly. Different brands have different warranty structures, and the details matter far more than the headline number. A "lifetime warranty" is a marketing term — most are fully comprehensive for years 1–10, then become prorated (you pay an increasing percentage of costs after that). Labor coverage is typically zero unless your contractor holds a specific brand certification (GAF Master Elite, CertainTeed SELECT ShingleMaster). Transfer terms vary: some warranties are non-transferable when you sell the house, which reduces your resale value. Read the actual warranty document — not the brochure — before making any decision based on warranty claims.
The installer — by a significant margin. Industry data consistently shows that 90%+ of premature roofing failures are installation failures, not product defects: wrong nail depth, wrong nail zone, insufficient nail count, improper flashing, inadequate ice & water shield. The shingle is roughly 30% of the roofing system. The other 70% is what the crew does: nailing technique, underlayment quality, flashing at penetrations and valleys, ventilation, and edge detail. A great crew installing an adequate shingle will protect your home for 25+ years. A careless crew installing a premium shingle will give you problems within 5. Spend your energy vetting the contractor first. The shingle decision comes after.
