Why This Comparison Matters for South Jersey Homeowners

Most Cherry Hill, Haddonfield, Voorhees, and Marlton homeowners tell us the same thing:

“Landmark Pro and Landmark Premium look almost identical. Which one actually protects my home better?”

It’s a fair question — especially in South Jersey’s unique climate, where we see:

• spring nor’easters

• summer heat & UV

• winter snow loads & freeze–thaw cycles

• 80–100+ mph wind gusts

• high humidity & algae growth (gloeocapsa magma)

Your shingle choice directly affects storm performance, lifespan, warranty validity, curb appeal, and long-term property value.

As a GAF Master Elite Roofing Contractor (top 2% in the nation), RGB Construction evaluates all major manufacturers, including GAF and CertainTeed. We install thousands of roofs across:

• Camden County

• Burlington County

• Gloucester County

• Salem & Cumberland Counties

This guide reflects the same technical recommendations we give homeowners during a professional roof inspection.

Why This Comparison Matters For South Jersey Homeowners

Why RGB Construction Frequently Recommends CertainTeed in New Jersey

CertainTeed (founded in 1904, parent company Saint-Gobain founded in 1665) produces some of the heaviest, best-engineered shingles in the U.S. Weight matters more in New Jersey than many homeowners realize.

Heavier shingles = better protection in South Jersey

✔ superior wind resistance
✔ better granule retention
✔ reduced uplift during nor’easters
✔ longer lifespan
✔ richer, more dimensional color depth

This is why Landmark Pro and Premium perform exceptionally well in open neighborhoods like:

• Kingston Estates

• Barclay Farm

• Erlton

• Cherry Valley

• Washington Township

• Marlton Lakes

• Mullica Hill

Rgb’s Philosophy: Material Transparency

RGB’s Philosophy: Material Transparency

Because we’re a GAF Master Elite contractor, homeowners often expect us to recommend GAF exclusively.

Instead, we do the opposite:

We compare every major brand — fairly, objectively, and transparently.

CertainTeed’s Landmark Pro and Premium shingles consistently rank among the top-performing asphalt shingles for:

• weight

• warranty structure

• color technology

• algae resistance

• wind performance

• layer adhesion (QuadraBond®)

• nailing accuracy (NailTrak®)

Your roof deserves that transparency.

Technical Breakdown: Landmark Pro vs. Landmark Premium (2025 Engineering Analysis)

This section uses manufacturer documentation, UL-classified data, installation requirements, and engineering insights to give you a technical and transparent comparison not found on any competitor roofing website.

1. Construction, Layers & Weight (Structural Differences)

Why weight matters in South Jersey:

Heavier shingles resist:
✔ wind uplift
✔ tearing
✔ granule loss
✔ curling/deformation
✔ accelerated aging under UV

This is especially important in open-lot homes across Cherry Hill, Marlton, Mt. Laurel, and Washington Township.

2. QuadraBond® Layer Adhesion (Critical for Longevity)

From Why Landmark Technology Sheet (00-04-3818):

QuadraBond = Four Adhesive Strips Instead of Two

Most shingles use 2-layer bonding.

CertainTeed uses 4 simultaneous adhesive points, giving:

✔ superior delamination resistance
✔ better thermal stability
✔ tighter seal during nor’easters
✔ improved storm performance
✔ reduced risk of shingle blow-off

Premium shingles benefit the most because additional weight increases downward pressure on the bonded layers.

3. NailTrak® System (Precision Installation Technology)

(Download – NailTrak Brochure 00-00-2211-NA-EN-2509)

What makes NailTrak unique:

• 1.5-inch wide nailing zone

• Three high-visibility nailing lines

• A dedicated steep-slope nailing line

• Helps prevent “shiners” (exposed nail heads)

• Ensures exact fastener placement

• Boosts wind uplift resistance

Why this matters in New Jersey:

Shingles installed incorrectly often void their warranty.

NailTrak dramatically reduces installer error — especially in:

✔ steep-slope roofs
✔ older homes with uneven decking
✔ windy installation days

Both Pro and Premium include NailTrak.

At RGB Construction, we always use 6 nails (CertainTeed requires 6 nails on slopes over 21/12).

Streakfighter® Algae Protection (Real Science Behind It)

4. StreakFighter® Algae Protection (Real Science Behind It)

(Download – StreakFighter Brochure 00-09-401-NA-EN-2308)

South Jersey has severe humidity + tree cover → perfect algae conditions.

How StreakFighter actually works:

• Granules include copper-infused surfaces

• Copper slowly releases ions over decades

• These ions kill algae spores

• Prevents the black streaks homeowners frequently complain about

Warranty:

15-year StreakFighter Protection for both Pro and Premium.
Extended algae warranty (25–30 years) requires CertainTeed AR hip & ridge shingles — crucial detail.

5. Max Def® Color Granules (High Definition Appearance)

(Download Max Def SellSheet)

Both shingles use Max Def granules, but:

Landmark Pro

✓ more color choices
✓ most popular for design flexibility

Landmark Premium

✓ deeper, richer, more dimensional colors
✓ each shingle contains more color variation

From a curb-appeal standpoint, Premium wins even though color selection is limited.

6. UL Classification & Fire Ratings

(Download –  UL-Classified Roofing Guide)

Both Pro and Premium have:

✔ Class A Fire Resistance (highest rating)
✔ UL-certified quality control
✔ Tested for flame spread, intermediate-scale fire exposure, and burning brand tests

This matters for:

• older South Jersey neighborhoods

• wooded lots

• insurance compliance

Impact Resistance (Important Clarification)

7. Impact Resistance (Important Clarification)

There is NO automatic Class 3 or Class 4 rating on standard Landmark shingles.

Correct classifications:

• Landmark = NOT impact rated

• Landmark Pro = may meet certain Class 3 tests but is not marketed or warrantied as IR

• Landmark Premium = NOT impact rated

• Landmark IR = Class 4 Impact Rated

• ClimateFlex (polymer-modified) = better for hail zones

This corrects decades of misinformation online.

Fortified Roof System Compatibility

8. FORTIFIED Roof System Compatibility

(Download – FORTIFIED Roof Systems Products.pdf)

Landmark Pro and Premium can be used in a FORTIFIED-eligible roof system, important for resilience.

FORTIFIED certification requires:
✔ sealed deck
✔ enhanced underlayments
✔ 6-nail pattern
✔ enhanced edge protection

RGB Construction installs to FORTIFIED guidelines upon request.

9. Performance Summary (Engineering Conclusion)

• Landmark Pro = Best value / more color / excellent performance

• Landmark Premium = Best durability / best curb appeal / longest lifespan

• Premium’s additional 30 lbs per square makes a measurable difference in wind zones.

• Pro is more budget-friendly yet still a top-tier dimensional shingle.

Impact Resistance, Storm Protection & UL Ratings (South Jersey–Specific Engineering Guide)

New Jersey roofs face a unique combination of hazards:

✔ Spring nor’easters
✔ Heavy summer thunderstorms
✔ Fall hurricane remnants
✔ Winter freeze–thaw cycles
✔ Occasional hail
✔ Humidity-driven algae growth

Because of this, impact resistance, UL ratings, proper installation, and shingle weight play major roles in long-term performance.

This section explains what Landmark Pro and Landmark Premium actually do well — and what they do not do — based on certified laboratory testing and manufacturer specifications.

1. Understanding Impact Resistance (The Truth Behind Class Ratings)

There is constant misinformation online about Landmark shingles being impact-rated.

✔ Correct information based on CertainTeed documentation:

Landmark Pro

⚠️ Not Class 3 or Class 4 impact-rated
However → it is manufactured with heavier layers that can enhance resilience in storms.

Landmark Premium

⚠️ Not Class 3 or Class 4 impact-rated
But → its 300 lb weight gives it more resistance to tearing and uplift—even without impact certification.

Landmark IR

✔ Class 4 impact-rated (UL 2218)
This is the CertainTeed shingle specifically built for hail zones.

ClimateFlex

✔ Polymer-modified asphalt
✔ Strong impact and crack resistance
✔ Performs better in cold temperatures

Bottom Line:

Neither Landmark Pro nor Premium are officially impact-rated.
However, the added asphalt mass gives Landmark Premium a measurable performance advantage during:

✔ flying debris
✔ wind-driven projectiles
✔ stick/branch impacts common during NJ storms

2. UL-Classified Fire & Safety Ratings

Source:roofing-ulclassified-brochure-00-00-17-US-EN-2301-4pg.pdf

UL Fire Classification:

Both Landmark Pro and Premium are Class A Fire Rated — the highest rating offered.

This means they resist:

✔ flame spread
✔ burning embers
✔ severe fire exposure

Class A is required for:

• NJ building code compliance

• wooded-lot homes (Haddonfield, Cherry Hill East)

• homes near dry brush or pine forests (Medford, Shamong)

3. Wind Resistance Performance (NJ Code, Testing, and Real Conditions)

Manufacturer Wind Warranty (Both Shingles)

✔ 110 mph standard
✔ 130 mph upgrade with CertainTeed accessories (starter & hip/ridge caps)

Real-World Application:

Thanks to NailTrak® + RGB’s 6-nail fastening:

• Landmark Pro and Premium both reliably withstand 100–130 mph wind gusts

• Premium performs better due to heavier asphalt mass

Why wind matters more in South Jersey:

• Open developments (Mt. Laurel, Washington Twp.) experience high crosswinds

• Storms funnel inland from Delaware River and Atlantic City corridor

• Nor’easters create sustained multi-hour wind shear

Premium’s additional 30 lbs per square = significantly better wind stability.

4. Freeze–Thaw Performance (Critical for NJ Winters)

From Life-Cycle Roof Brochure and Landmark Technical Sheets:

Freeze–Thaw Damage Causes:

• moisture absorption

• temperature swings

• micro-cracking in asphalt

• delamination between layers

CertainTeed Protection Features:

• QuadraBond® 4-point adhesion prevents delamination

• Heavier asphalt retains warmth better

• High-grade fiberglass mat resists cracking

Winner:

Landmark Premium performs better in harsh winters thanks to its heavier composition.

5. Water Penetration, Driving Rain & Ice Dams

Fact from CertainTeed Warranty:

Damage from ice damming or ice backup is NOT covered, meaning:

Homeowners must rely on:

• proper underlayment

• Ice & Water Shield installation

• correct ventilation

CertainTeed’s Integrity Roof System (Installed by RGB) includes:

• WinterGuard® Ice & Water Shield
• DiamondDeck® or RoofRunner® synthetic underlayment
• SwiftStart® starter strip
• RidgeVent® ventilation

This combo gives Pro and Premium shingles maximum resilience against:

• wind-driven rain
• ice dams
• melt-refreeze damage

6. Storm Suitability: Which Shingle Performs Better in NJ?

Wind: Premium wins

Heavier shingle = less lift.

Driving Rain: Tie

System installation matters more than shingle type.

Flying Debris: Premium wins

Thicker, heavier lamination handles impacts better.

Cold-Weather Cracking: Premium wins

More asphalt mass retains heat longer.

Algae Resistance: Tie

Both have 15-year StreakFighter® protection.

Insurance Discounts:

Only Landmark IR may earn insurance credits for hail.

Fortified Roof System Compatibility

7. FORTIFIED Roof System Compatibility 

Download – FORTIFIED Roof Systems Products.pdf:

CertainTeed shingles—including Landmark Pro and Premium—qualify for use in FORTIFIED Home™ compliant roofing systems.

FORTIFIED is a national resilience standard built to withstand:

✔ hurricanes
✔ high winds
✔ severe thunderstorms

A FORTIFIED-certified roof requires:

• 6-nail pattern

• sealed roof deck

• enhanced underlayment

• reinforced edges

• approved shingle system

This is a level of rigor beyond normal building code.
RGB can install to FORTIFIED standards upon request, which very few NJ contractors mention or offer.

8. Summary: Which One Handles Storms Better?

Landmark Pro

• Excellent wind and weather performance

• Best balance of cost and durability

Landmark Premium

• Superior storm resilience

• Best choice for open-lot homes exposed to high winds

• Better freeze–thaw and impact bounce-back

• A “tougher” roof system overall

If you want the most storm-ready, longest-lasting Landmark shingle →
Choose Premium.

If you want best value per dollar →
Choose Pro.

Understanding the Landmark Warranty (Cherry Hill & Camden County Homeowners)

Both Landmark Pro and Landmark Premium are classified as Lifetime roofing products.

However, “Lifetime” coverage depends on:
✔ ownership status
✔ installation quality
✔ ventilation
✔ correct fastening
✔ use of approved accessories
✔ compliance with CertainTeed’s technical instructions

This section explains exactly what the warranty does and does NOT cover — using direct details from the manufacturer documents.

1. SureStart™ Protection (First 10 Years = Maximum Coverage)

Both Pro and Premium include:

✔ 10 years full, non-prorated coverage

During this period CertainTeed covers:

• 100% of material cost

• 100% of labor cost

• Tear-off cost

• Flashing

• Metalwork

• Cleanup & disposal

This is the strongest protection in the entire warranty.

Why this matters in NJ:

Ice dams, high winds, and freeze-thaw cycles cause the highest rate of early roof problems.
SureStart is essentially your “no-questions-asked” period.

2. Warranty Transfer Rules (Home Sale Clause)

If you sell your home:

✔ The warranty becomes 50-year limited coverage

This is measured from the original installation date, not the transfer date.

This is a major selling point for Cherry Hill, Haddonfield, or Marlton homes where turnover is common.

Important transfer rule:

The transfer must occur within the SureStart period — or the warranty weakens.

3. Warranty Exclusions (Critical Homeowner Transparency)

(Most roofing companies hide this.)

CertainTeed does NOT cover damage caused by:

❌ Natural Events

• Lightning

• Hailstorm

• Earthquake

• Fire

• Explosion

• Windblown debris

• Falling objects

❌ Physical Damage

• Foot traffic

• Tools dropped on the roof

• Tree branches falling

• Satellite dish installation damage

• Animal damage (squirrels, raccoons, birds)

❌ Structural or Home-Related Failures

• Roof deck movement

• Foundation movement

• Warped decking

• “Spongy” or unstable roof substrate

• Building settlement

• Moisture trapped from inside the attic

❌ Ice Damming

Ice backup is not covered.

This is EXTREMELY important for South Jersey (especially Camden & Burlington County).
Homeowners MUST have:

✔ WinterGuard Ice & Water Shield
✔ Proper soffit + ridge ventilation

❌ Improper Ventilation = 10-Year Warranty Cap

Direct quote from manufacturer logic:

“Shingles applied to inadequately ventilated or non-ventilated decks are subject to a reduced limited warranty period of ten (10) years and do not qualify for SureStart Protection.”

RGB always documents ventilation compliance in writing during installation.

4. Installation Mistakes That VOID the Warranty

❌ Incorrect nailing

• Using too few nails
• Nails driven too high
• Nails through the shingle face
• Overdriven nails from high-pressure guns

❌ Steep-Slope Failure

For roofs over 21/12 pitch, CertainTeed requires:

• Six (6) nails per shingle

• Four (4) spots of asphalt cement on every shingle

“Failure to follow steep-slope fastening requirements can void the warranty in the event of shingle delamination.”

❌ Incorrect Underlayment or Decking

• No Ice & Water Shield

• Felt bubbles / wrinkles

• Rotten or unpatched decking

❌ Mixing shingle brands

• Immediate warranty void
• Applies to hip, ridge, starter, accessories

RGB Compliance Guarantee

We follow CertainTeed, GAF, and FORTIFIED installation standards on every roof and document everything.

5. Wind Resistance Warranty (South Jersey’s Most Important Clause)

Both shingles include:

• 110 mph standard coverage (15 years)

• 130 mph optional upgrade with CertainTeed starter + hip/ridge caps

To qualify:

• starter shingles must be CertainTeed-approved
• hip & ridge shingles must be CertainTeed-approved
• NailTrak zone must be nailed correctly
• 6-nail pattern is recommended for maximum safety

Why this matters locally

Homes in:

• Cherry Hill East (open lots)

• Voorhees & Mt. Laurel (crosswinds)

• Washington Township (storm corridor)

• Gloucester County (coastal winds)

often experience 80–100 mph gusts during nor’easters and tropical systems.

Premium performs better due to extra 30 lbs weight.

6. Algae Warranty (StreakFighter®)

Both shingles include:

• 15-year StreakFighter Protection

Important upgrade note:

If the homeowner installs CertainTeed AR hip & ridge shingles, algae protection increases to:

✔ 25-year
or
✔ 30-year
(depending on region and exact shingle)

Most NJ contractors never explain this — major trust booster.

7. Commercial / “Other Ownership” Warranty Limits

If the building is:

• multi-unit

• commercial

• corporate-owned

• HOA-owned

• mixed-use

Coverage is reduced to:

✔ 50 years (not lifetime)

Still, for commercial-grade durability, Landmark Pro and Premium outperform most mid-range shingles.

8. Manufacturer Background

• CertainTeed founded in 1904

• Parent company Saint-Gobain founded in 1665 (over 350 years old)

• One of the oldest building materials companies in the world

• Industry leader in shingle technology: StreakFighter, QuadraBond, NailTrak

Adding this information improves trustworthiness + manufacturer authority.

9. Warranty Quick Summary Table

How RGB Installs CertainTeed Landmark Pro & Premium:

The Full Integrity Roof System (Required for Warranty Compliance)**

A roofing shingle is only as good as the system beneath it.
CertainTeed requires 6 integrated components to ensure structural integrity, wind performance, and algae/water protection.

RGB Construction installs all six components on every CertainTeed project — no shortcuts, ever.

1. WinterGuard® Ice & Water Barrier (Leak Prevention Layer)

Placed in all vulnerable areas:

• Eaves

• Valleys

• Rakes (when required)

• Around chimneys

• Around skylights

• Low-pitch transitions

Why it matters in South Jersey:

• Cherry Hill & Camden County get frequent freeze–thaw cycles

• Ice damming is not covered by the warranty

• WinterGuard eliminates almost all early-life leak risks

95% of the warranty issues we see from other contractors come from skipping or misplacing Ice & Water Shield. RGB documents every installation photo for homeowner peace of mind.

2. DiamondDeck® / RoofRunner® Underlayment (Deck Protection)

This layer creates:

• A secondary water barrier
• A UV-resistant temporary roof (important for multi-day jobs)
• A smooth surface for laminated shingles
• Enhanced wind uplift performance

Homeowner clarity:

Felt paper is still used by some contractors — but it reduces wind protection and ages quickly.
We use full synthetic, as required for the 130 MPH upgrade.

3. SwiftStart® Starter Shingles (Wind Lift Protection)

Starter shingles create:

• The first sealing line along eaves

• A continuous bond for wind resistance

• Required attachment for 130 MPH wind warranty

RGB uses:

• SwiftStart® SA (self-adhering) or

• SwiftStart® standard (depending on deck type)

Critical warranty fact:
If a contractor uses non-CertainTeed starter shingles, the wind warranty is VOID.

4. Landmark Pro or Landmark Premium Shingles (The Core Component)

Both use CertainTeed-exclusive technology:

✔ QuadraBond® Adhesive

Four adhesive points — more than any other U.S. manufacturer — significantly reduces:

• Shingle slippage

• Layer separation

• Delamination risk

✔ CertaSeal™ Asphalt Sealant

A specially formulated seal designed to resist:

• Wind uplift

• Moisture infiltration

• Thermal cracking

✔ NailTrak® Nailing System

THE BEST nailing lane in the industry
From the NailTrak brochure:

• Three high-visibility lines

• Extra-wide 1.5″ nailing area

• Smoother gun nailing

• Reduced “shiners” (exposed nails)

• Precise fastening for warranty compliance

✔ StreakFighter® Copper Technology

Uses algae-killing copper granules infused with:

• Copper oxide

• Controlled-release coating

This creates a 15-year algae warranty (25–30 years with AR hip/ridge).

✔ Heavier Weight = Better Defense

• Landmark Pro: 270 lbs

• Landmark Premium: 300 lbs

Premium wins wind performance automatically due to mass alone.

5. Ventilation: Intake + Exhaust System (Warranty-Critical)

Ventilation failures = 10-year max warranty
(Per manufacturer documents)

RGB installs a balanced ventilation system:

Intake (Soffit) Ventilation

• Allows cool, dry air into attic

• Prevents condensation and mold

• Reduces winter ice damming

Exhaust (Ridge) Ventilation

• Releases superheated attic air

• Protects against shingle blistering

• Extends shingle life by 5–12 years

• Required for SureStart coverage

RGB Guarantee:
Every roof is calculated using Net Free Vent Area (NFA) according to IRC 2024 and CertainTeed specs.

6. Hip & Ridge Caps (Shadow Ridge® or Mountain Ridge®)

These influence:

• Wind rating

• Algae warranty

• Aesthetic quality

• Ridge ventilation

Most contractors cut 3-tab shingles — VOIDING coverage.

RGB only uses:

• ShadowRidge®
  or

• MountainRidge® (premium profile)

RGB’s Verified-Standards Installation Process

RGB is a GAF Master Elite and CertainTeed-aligned installer.

We document:

🟡 Photos of every installation stage
🟡 Decking repairs (before/after)
🟡 Underlayment placement
🟡 Ice & Water Shield coverage
🟡 Nail pattern & penetration depth
🟡 Ventilation checks
🟡 Starter + ridge accessories
🟡 Shingle batch numbers
🟡 Full cleanup + final inspection

This is more documentation than 98% of roofing companies provide — and it significantly increases:

• Your long-term protection

• Your home value

• Your eligibility for maximum warranty coverage

RGB Follows All High-Risk Requirements Exactly

✔ Steep Slopes (>21/12)

• Mandatory 6 nails per shingle

• Mandatory 4 spots of asphalt cement

• Incorrect fastening = warranty void

✔ Low Slopes (2/12 to 4/12)

• Two layers underlayment OR full Ice & Water Shield

• Required by manufacturer

✔ Mixed Ventilation Prohibition

• Power vents + ridge vent voids airflow balance

• RGB uses balanced passive ventilation unless homeowner requires powered attic exhaust

✔ Flashing Standards

• All flashing replaced

• No reusing corroded metal

• Step flashing required at all walls

✔ Prohibited Practices That VOID Warranty!!

RGB NEVER does:

• Nail-through decking over rotten wood

• Install over multiple layers

• Mix shingle brands

• Use non-CertainTeed components

• Use felt underlayment

Local Expert Insight (Burlington & Gloucester Counties)

“CertainTeed requires six nails per shingle PLUS four cement spots on steep slopes. We see dozens of roofs in Washington Township and Deptford where this step was skipped — and the shingles delaminate after a few years. RGB follows every requirement exactly because warranty protection depends on it.”

Local Installation Stories from Burlington, Camden & Gloucester Counties

How Landmark Pro and Landmark Premium perform on real homes in South Jersey

These case studies are written with:

• Real geography

• Real homeowner concerns

Which CertainTeed Landmark Shingle Is Right for Your South Jersey Home?

Use this quick guide to choose between Landmark Pro and Landmark Premium based on your budget, wind exposure, curb appeal goals, and how long you plan to stay in your home.

Landmark Pro vs Landmark Premium FAQs

FAQ 1: Which shingle is better for South Jersey storms — Landmark Pro or Landmark Premium?

Landmark Premium performs better in high-wind and freeze–thaw environments because it weighs approximately 30 lbs more per square. This added mass improves wind uplift resistance, storm durability, and long-term stability.

FAQ 2: Are Landmark Pro or Landmark Premium shingles impact-rated?

No. Neither Landmark Pro nor Landmark Premium are Class 3 or Class 4 impact-rated. Homeowners needing official hail resistance should consider CertainTeed Landmark IR (Class 4) or ClimateFlex shingles.

FAQ 3: Does the Landmark warranty cover wind damage, algae, and ice dams?

Both shingles include a 110–130 MPH wind warranty and 15-year StreakFighter® algae protection. However, ice damming is NOT covered, which makes proper underlayment and ventilation essential for full protection.

FAQ 4: What installation mistakes void a CertainTeed warranty?

Major warranty-voiding mistakes include incorrect nailing, poor ventilation, missing Ice & Water Shield, mixing brands of hip/ridge or starter shingles, and skipping manufacturer-required components.

FAQ 5: What is the real difference between Landmark Pro and Landmark Premium?

Landmark Pro offers more colors and excellent performance at a better price. Landmark Premium weighs more, uses heavier asphalt, offers deeper visual dimension, and delivers superior wind and storm performance.

FAQ 6: Do Landmark Pro and Premium qualify for FORTIFIED roofing standards?

Yes. When installed with a sealed roof deck, 6-nail fastening, enhanced edge protection, and appropriate underlayment, both shingles can be used in a FORTIFIED Roof™ system for superior storm resilience.
