- County Roofing Systems holds certifications with both manufacturers allowing honest comparison based on your specific needs
You need a quality roof that doesn’t destroy your budget.
GAF Timberline HDZ and Owens Corning Oakridge represent the entry point to premium architectural shingles from the industry’s two leading manufacturers.
Homeowners should be aware of key differences in durability, warranties, and algae protection when choosing between these products.
Both offer substantial upgrades over three-tab shingles—better wind resistance, dimensional shingles appearance, longer warranties.
One of the main advantages of architectural shingles is their superior durability, enhanced aesthetic appeal, stronger wind resistance, and longer warranties compared to standard asphalt shingles.
And both cost roughly the same, making them direct competitors for Nassau County homeowners seeking value without compromising quality.
These architectural roofing shingles provide the aesthetic appeal of premium materials at accessible pricing. Both are asphalt roofing shingles engineered with multiple layers for enhanced durability. Architectural shingles are a premium type of asphalt shingles, introduced to the market in the 1970s and 1980s as a stylish and durable alternative to traditional roofing materials.
Here’s what separates these products as roof shingles for your home. Timberline HDZ includes StainGuard Plus algae protection warranted for 25 years, LayerLock technology for enhanced wind resistance, and the backing of North America’s largest roofing manufacturer.
Oakridge offers solid construction at slightly lower pricing, good wind resistance, but no algae protection included.
Both Owens Corning Oakridge and GAF Timberline HDZ shingles are designed to mimic the look of premium roofing materials like cedar shake and slate tile.
That’s a significant omission for Long Island’s humid coastal climate.
That algae warranty difference alone often determines which product makes more sense for your Nassau County home.
Product Overview: Oakridge vs. Timberline HDZ Architectural Shingles
Let’s establish what each product actually is before comparing them.
GAF Timberline HDZ represents GAF’s flagship architectural shingle line and the best-selling residential roofing product in North America.
An architectural shingle roof is a higher class of roofing compared to standard 3-tab shingles, offering enhanced durability, performance, and visual appeal. Architectural shingles are also known as dimensional or laminated shingles, made up of multiple layers of asphalt-coated fiberglass that are laminated and bonded together.
These shingles are composed of a fiberglass base, mineral granules, and asphalt, which define their quality and appearance. The bonded layers give architectural shingles a thicker, more durable structure and a dimensional, high-definition profile with noticeable depth.
The shingles use LayerLock technology bonding shingle layers together for enhanced wind resistance.
Architectural shingles are designed to mimic the look of premium roofing materials, such as cedar shake and slate tile, providing exceptional aesthetic appeal and curb appeal.
The textures of these shingles imitate natural materials, adding visual interest and architectural authenticity. They can simulate the impressive look of genuine wood shakes or natural slate tiles without the installation and maintenance issues associated with those materials. Architectural shingles are available in a wide variety of color options to complement almost any home.
StrikeZone nailing area is 99.9% wider than traditional shingles.
This makes proper installation easier and more reliable.
StainGuard Plus algae protection comes standard, warranted for 25 years. Wind resistance reaches 130 MPH when installed with GAF’s complete roofing system.
Limited lifetime warranty covers materials. Available in 20+ colors.
Pricing typically runs $95-120 per square installed for Nassau County projects.
Owens Corning Oakridge positions as their value-oriented architectural shingle.
The shingles provide basic dimensional appearance with reasonable wind resistance and Owens Corning’s manufacturing quality. Like Timberline HDZ, Oakridge architectural shingles are composed of multiple layers of fiberglass mat and asphalt, which are bonded together for added strength and durability.
This construction gives them a dimensional, high-definition look and depth that sets them apart from standard 3-tab shingles.
Oakridge shingles are also available in a range of colors and are designed to mimic the appearance of premium materials like cedar and slate, with realistic textures that enhance curb appeal. As a higher class of shingle, they are known for their long-lasting performance and aesthetic value.
They’re a step up from three-tab shingles but lack the advanced features found in Owens Corning’s premium Duration series.
Wind resistance reaches 110 MPH with proper installation, upgrading to 130 MPH when using Owens Corning’s complete system. Limited lifetime warranty covers materials.
Available in 15-18 colors.
Pricing typically runs $85-110 per square installed—roughly $5-15 per square less than Timberline HDZ.
The price difference on an average 2,000 square foot Nassau County roof (20 squares) amounts to $100-300. Not dramatic, but meaningful for budget-conscious homeowners.

Algae Resistance: The Critical Difference
This is where these products diverge most significantly.
GAF Timberline HDZ includes StainGuard Plus technology as a standard feature. Copper-containing granules embedded in the protective layer release algae-fighting copper when exposed to rain.
This prevents Gloeocapsa magma algae from establishing itself on your shingles.
GAF warranties this protection for 25 years.
For Nassau County’s humid coastal climate, that 25-year algae warranty is crucial. Without protection, black algae streaks typically appear on roofs within 3-5 years.
Once algae takes hold, it spreads rapidly.
It creates unsightly dark streaks that dramatically reduce curb appeal and can force premature roof replacement purely for aesthetic reasons.
Owens Corning Oakridge includes no algae-resistant technology. No copper granules. No algae warranty.
Your roof is as vulnerable to algae growth as basic three-tab shingles from 30 years ago.
The Nassau County Problem
This creates a real problem for Nassau County homeowners. Our proximity to the Atlantic Ocean means regular moisture, high humidity, and perfect conditions for algae growth.
Neighborhoods across Nassau County show countless examples of roofs with black streaks ruining otherwise well-maintained homes.
The $100-300 you save upfront by choosing Oakridge over Timberline HDZ will seem insignificant when black streaks appear 4-5 years later.
Your options then are expensive professional cleaning that may damage shingles and void warranties, living with unsightly appearance that hurts property value, or premature roof replacement costing $8,000-15,000+ just to eliminate algae staining.
County Roofing Systems strongly recommends algae-resistant shingles for virtually all Nassau County installations. The modest upfront premium is insurance against a problem that’s nearly inevitable in our climate.
Wind Resistance and Storm Performance
Nassau County’s coastal location means wind resistance matters for both nor’easters and occasional tropical systems.
GAF Timberline HDZ achieves 130 MPH wind resistance when installed as part of GAF’s complete roofing system. This includes Timberline HDZ shingles, WeatherWatch underlayment, starter strip shingles, and Seal-A-Ridge hip and ridge cap shingles.
GAF’s LayerLock technology mechanically bonds shingle layers together.
This enhances uplift resistance during high winds and helps prevent shingle blow off during storms.
GAF Timberline HDZ shingles are also eligible for the WindProven Limited Wind Warranty when installed with required accessories. This warranty, available when installed by a Master Elite contractor like County Roofing Systems, has no maximum wind speed limitation.
If wind damage occurs despite proper installation, GAF covers repairs regardless of measured wind speed.
Most manufacturer wind warranties cap coverage at the rated speed (110 MPH, 130 MPH, etc.), making GAF’s unlimited coverage notable.
Owens Corning Oakridge achieves 110 MPH wind resistance with standard installation methods, upgrading to 130 MPH when using Owens Corning’s complete system.
This includes their specific starter strips and underlayment.
The wind warranty is traditional—coverage up to the specified rating.
Architectural shingles, like both Timberline HDZ and Oakridge, provide effective protection against wind uplift and blow-off. Some products are rated to withstand winds up to 120 miles per hour, making them a strong choice for storm-prone areas.
In Nassau County’s actual wind environment, both products perform adequately when properly installed. Our coastal storms typically produce sustained winds of 40-70 MPH with gusts to 90-110 MPH.
Both Oakridge and Timberline HDZ handle these conditions effectively with proper installation and quality accessories.
The difference becomes relevant during rare extreme events—hurricanes bringing sustained 80+ MPH winds or extreme nor’easters with 100+ MPH gusts.
Timberline HDZ’s higher standard rating and WindProven warranty provide additional security for these worst-case scenarios.

Warranty Coverage Comparison
Both manufacturers offer limited lifetime warranties, but the details and available enhancements differ.
GAF’s standard limited lifetime warranty on Timberline HDZ covers manufacturing defects for as long as you own your home. When installed by a GAF Master Elite contractor like County Roofing Systems, you gain access to enhanced warranty options.
The System Plus limited warranty provides 10 years of coverage on both materials and workmanship.
The Golden Pledge limited warranty extends that to 25 years on materials and workmanship, plus 50-year coverage on manufacturing defects.
GAF’s Golden Pledge limited warranty is particularly valuable. It covers both materials and labor for 25 years—if anything goes wrong with your roof, GAF pays for shingles and installation.
This level of protection is only available through Master Elite contractors.
It requires using GAF’s complete roofing system.
The cost is typically $200-600 depending on roof size.
Owens Corning’s standard limited lifetime warranty on Oakridge covers material defects similarly. When installed by an Owens Corning Platinum Preferred contractor like County Roofing Systems, you can access the Preferred Protection limited warranty.
This provides 10 years of materials and workmanship coverage.
The warranty options for Oakridge are more limited than what’s available with Owens Corning’s premium Duration series. You won’t find the 25 or 50-year enhanced warranties that Duration offers.
Oakridge is positioned as a value product with correspondingly simpler warranty structure.
County Roofing Systems holds both GAF Master Elite and Owens Corning Platinum Preferred certifications. This dual certification means we can offer you the best possible warranty from either manufacturer rather than being limited to whatever our contractor qualifications allow.
Pricing and Overall Value Analysis
Let’s analyze the complete value proposition including upfront costs and long-term considerations.
Owens Corning Oakridge typically runs $85-110 per square installed for Nassau County projects. For a 2,000 square foot roof (approximately 20 squares including waste), total installed cost including tear-off, underlayment, ventilation, and accessories runs $7,000-10,500.
GAF Timberline HDZ typically runs $95-120 per square installed. For that same 2,000 square foot roof, total installed cost runs $7,500-11,500.
The difference between Oakridge and Timberline HDZ for an average Nassau County home is approximately $300-1,000.
The Critical Value Question
Here’s the critical value question: Is 25 years of algae protection worth $300-1,000?
Consider what happens without algae protection. Black streaks appear within 3-5 years in Nassau County’s humid climate.
Professional roof cleaning costs $500-1,200 but may damage shingles, void warranties, and only provides temporary relief.
Algae typically returns within 1-2 years.
Premature roof replacement to eliminate unsightly algae staining costs $8,000-15,000.
With 25-year algae protection, your roof stays clean throughout its expected lifespan. No cleaning expenses. No staining affecting property value.
No difficult decision about replacing a structurally sound roof just because it looks terrible.
The math strongly favors Timberline HDZ for most Nassau County homeowners. The modest $300-1,000 premium buys protection against a problem that’s nearly inevitable without it.
The break-even occurs if avoiding even one professional cleaning or extending your roof’s useful life by just 1-2 years before premature aesthetic replacement becomes necessary.
County Roofing Systems occasionally recommends Oakridge for specific situations. Extremely tight budgets where every dollar matters. Properties being prepared for immediate sale where long-term algae concerns aren’t relevant.
Homes with exceptional tree shading that dramatically reduces algae risk.
But for typical Nassau County homeowners planning to stay in their homes for 10+ years, Timberline HDZ provides substantially better value despite higher upfront cost.
We know that researching and planning home improvement upgrades can be a hassle.

Real-World Long Island Installation Examples
County Roofing Systems’ experience across thousands of Nassau County installations provides practical insights.
We’ve installed both Oakridge and Timberline HDZ on homes throughout Nassau County—from Hempstead to Glen Cove, from Long Beach to Port Washington. Homeowners can see the long-term results of their roofing choice on their own home, making it even more important to select the right product for lasting curb appeal.
The pattern is consistent.
Timberline HDZ roofs maintain clean appearance for decades while Oakridge roofs develop algae staining within 5-10 years.
Garden City Example
Two colonial homes on the same street replaced roofs the same year. One chose Oakridge to save $600 upfront.
The other chose Timberline HDZ.
Seven years later, the Oakridge roof shows significant black streaking while the Timberline HDZ roof remains clean. The homeowner with Oakridge paid $800 for professional cleaning that temporarily improved appearance.
But algae returned within 18 months.
Merrick Example
A homeowner insisted on Oakridge despite our recommendation of Timberline HDZ, citing budget constraints. Four years later, they called requesting options for dealing with algae streaks.
We explained that without algae-resistant shingles, the problem would recur regardless of cleaning.
They ultimately lived with the streaks until selling the home 8 years later, accepting a lower offer partially attributed to the roof’s poor appearance.
Successful Oakridge installations exist in specific circumstances. Homes with heavy tree shading blocking direct sun exposure show reduced algae growth.
Properties in very dry microclimates (rare in Nassau County) experience less aggressive algae.
And homes being prepared for immediate sale where long-term performance doesn’t matter can justify saving the upfront premium.
But these are exceptions. For typical Nassau County homes with normal sun exposure and homeowners planning to stay long-term, Timberline HDZ consistently proves the better value despite higher initial cost.
Which Product Should Nassau County Homeowners Choose?
The recommendation is straightforward for most situations. Timberline HDZ architectural shingles are a top choice for homeowners who want a balance of performance, warranty, and style.
These shingles not only provide excellent protection and durability, but also create architectural interest and depth that can elevate your home’s curb appeal.
The luxury appearance of these shingles can make your roof stand out, and their premium quality may increase your home’s resale value. Installing architectural shingles like Timberline HDZ is a smart investment for those seeking both beauty and long-term value.
Choose GAF Timberline HDZ If:
You plan to own your home for 7+ years and want protection against algae staining. You value peace of mind that comes with 25-year algae warranty.
You prioritize long-term value over minimal upfront savings.
You want access to GAF’s extensive contractor network and enhanced warranties. You can afford the $300-1,000 premium without significant budget strain.
Choose Owens Corning Oakridge Only If:
You face extreme budget constraints where every $100-200 matters critically. You’re preparing property for immediate sale and long-term performance isn’t relevant.
You have exceptional tree shading dramatically reducing algae risk (rare).
You’re combining installation with other extensive home improvements and need to minimize roofing costs to preserve budget for those priorities.
For the vast majority of Nassau County homeowners, Timberline HDZ represents better value. The modest premium buys protection against a problem that’s nearly guaranteed without it.
The break-even occurs quickly—one avoided cleaning or 1-2 years of extended useful life before aesthetic replacement becomes necessary pays for the difference.
County Roofing Systems recommends Timberline HDZ in roughly 90% of consultations where homeowners are comparing these products.
We recommend Oakridge for the remaining 10% where specific circumstances make the trade-offs acceptable.

For Nassau County homeowners comparing budget architectural shingles, GAF Timberline HDZ provides substantially better value than Owens Corning Oakridge despite costing $300-1,000 more for an average roof.
The critical difference is algae protection. Timberline HDZ includes 25 years of StainGuard Plus warranty while Oakridge offers no algae resistance.
In Nassau County’s humid coastal climate where algae growth is nearly inevitable, that protection difference outweighs the modest price premium within just a few years.
Both products offer adequate wind resistance (110-130 MPH), similar limited lifetime warranties on materials, and comparable installation requirements. Architectural shingles are known for being durable and resilient, making them a reliable choice for homeowners.
They are also often considered a more affordable option compared to other premium roofing materials like slate or wood shakes. But Timberline HDZ’s algae protection, broader color selection, larger contractor network, and enhanced warranty options make it the superior choice for most homeowners.
Oakridge makes sense only for specific situations—extreme budget constraints, properties being prepared for immediate sale, or unusual circumstances reducing algae risk.
For typical Nassau County homeowners planning to stay in their homes for 7+ years, Timberline HDZ’s long-term value justifies the higher upfront investment.
County Roofing Systems has served Nassau County for over 35 years. We hold both GAF Master Elite and Owens Corning Platinum Preferred certifications, giving us the expertise and qualifications to install either product to certified standards.
We can provide honest comparison based on your specific circumstances rather than pushing whichever brand we happen to be certified with.
