Looking for luxury roofing that actually performs?
Grand Manor delivers both.
These aren’t your standard architectural shingles. CertainTeed’s Grand Manor line sits at the top of their luxury collection, offering the dimensional beauty of natural slate without the weight, cost, or maintenance headaches.
We’ve installed Grand Manor roofs across Long Island for over 35 years. We’ve seen how they hold up through nor’easters, summer heat, coastal salt air, and everything else our climate throws at them.
Below, we’ll break down what makes Grand Manor different and whether these premium shingles are right for your home.
What Makes Grand Manor Different From Standard Shingles
Grand Manor uses a multi layer design with randomly stacked tabs, which enhances durability and resistance to harsh weather conditions.
This creates deep shadow lines and three-dimensional appearance that closely mimics natural slate roofing. You’re not looking at flat architectural shingles trying to fake texture. You’re looking at genuine dimensional quality.
The shingles measure significantly thicker than standard options. At approximately 425 pounds per square, they’re nearly twice the weight of typical architectural shingles.
That extra weight translates to superior durability, better insulation properties, and enhanced wind resistance. The multi-layer design provides superior protection against harsh weather conditions like snow, hail, and wind storms. You can feel the quality difference handling these shingles compared to lighter alternatives.
Compared to standard shingles, Grand Manor offers superior weather protection and a longer warranty, which justifies its higher price.
Integration With CertainTeed’s Complete System
Grand Manor is part of CertainTeed’s Integrity Roof System.
Every component from underlayment to ventilation is designed to work together. CertainTeed recommends using specific underlayment products for optimal performance of Grand Manor shingles. When you choose Grand Manor, you’re not just getting premium shingles. You’re getting a complete roofing solution engineered for maximum performance.
This system approach ensures compatibility across all components. Your warranty coverage reflects this integration, and the advantage of professional installation is that it allows you to fully leverage the high wind resistance features of Grand Manor shingles.
Let’s talk about how Grand Manor looks on your home.

Design That Elevates Your Home’s Appearance
The visual impact is substantial.
Choosing CertainTeed Grand Manor shingles allows homeowners to select colors and styles that enhance the architectural style and appearance of their building.
Multi-layered design creates texture and depth that flat shingles simply cannot match. Each shingle features randomly placed tabs in varying widths and depths, producing authentic slate appearance.
Color Options That Last
Grand Manor comes in a sophisticated color palette.
The colors feature CertainTeed’s Max Def technology. Specially formulated granules create richer, more vibrant hues that resist fading over time.
Popular options include Aged Pewter, Burnt Sienna, Cobblestone Gray, Georgetown Gray, and Valley Stone.
Black Pearl offers a rich, sophisticated appearance that adds a luxurious, high-end finish to your home.
Colonial Slate provides a classic, elegant look that enhances curb appeal with its refined slate-like tones.
Weathered Wood highlights the textured surface and brings a warm, architectural appeal for a premium, timeless look. Each works beautifully with both traditional and contemporary architecture.
The dimensional profile catches and reflects light throughout the day. This creates dynamic appearance that changes with the sun’s angle. Your roof becomes a design feature rather than just overhead protection.
The shingles are available in a variety of colors, including Black Pearl and Colonial Slate, and are designed to enhance the aesthetic appeal of homes.
Where Grand Manor Shines
Complex rooflines showcase Grand Manor’s quality best.
Colonia
l, Tudor, Mediterranean, and craftsman-style homes all benefit from the textured appearance. Even simpler ranch or Cape Cod designs gain visual sophistication.
The shingles work particularly well where the roof is a prominent architectural feature. If your home’s design emphasizes roofline details, Grand Manor enhances those elements.
Now let’s talk about performance in Long Island weather.
How Grand Manor Handles Long Island Weather
Beauty alone doesn’t make a great roof.
Grand Manor backs up its appearance with serious performance credentials that matter for coastal homeowners.
These shingles provide added protection and are specifically designed to withstand harsh weather conditions, including high winds and heavy snow.
Wind Resistance You Can Count On
Standard installation can withstand winds up to 110 mph, making Grand Manor shingles an excellent choice for homeowners seeking roofing that can resist high winds and severe weather.
When we install Grand Manor following complete CertainTeed specifications, that rating increases to 130 mph with appropriate warranty coverage. We’re a CertainTeed SELECT ShingleMaster, which means we meet those specifications exactly.
We’ve seen Grand Manor roofs survive major wind events without damage. Neighboring homes with lesser products suffered shingle loss. Grand Manor stayed put.
Fire Protection at the Highest Level
Class A fire rating means Grand Manor can withstand extended flame exposure without igniting.
This protects your family and property. It often translates to lower homeowners insurance premiums. Insurance companies recognize the value of top-tier fire protection.
Algae Resistance That Works
StreakFighter technology incorporates copper granules throughout the shingles. The shingles feature StreakFighter® algae resistance technology to prevent discoloration over time.
These copper particles inhibit algae growth and help prevent discoloration. In Long Island’s humid climate where dark streaks and discoloration commonly develop, this protection preserves your home’s appearance without constant cleaning.
Grand Manor roofs maintain their clean look far longer than untreated shingles. Homes in shaded areas or near trees may eventually develop some growth, but onset is delayed significantly.
Thermal Performance Benefits
The multi-layered construction provides better insulation than thinner shingles.
This helps regulate attic temperatures year-round. During summer months when dark shingles on standard roofs contribute to heat buildup, Grand Manor’s thickness provides a buffer.
This improved thermal performance can reduce energy costs. Your HVAC system doesn’t work as hard maintaining comfortable temperatures.
Let’s discuss installation requirements.

Installation Expertise Matters With Luxury Shingles
Grand Manor isn’t a DIY-friendly product.
These luxury shingles require experienced installation to ensure both performance and appearance meet expectations.
Weight Considerations
425 pounds per square means verifying your roof structure can support the load.
Most modern homes handle this without issue. Older homes or those with prior structural concerns may need reinforcement. We assess this during initial inspection and provide recommendations if strengthening is necessary.
Following the Integrity Roof System
Proper installation follows CertainTeed’s detailed specifications.
Appropriate underlayment layers. Correctly positioned starter strips. Precise nailing patterns. Proper flashing around all penetrations and transitions. These aren’t optional steps—they’re requirements for performance and warranty coverage.
As a CertainTeed SELECT ShingleMaster, we’ve proven our expertise through comprehensive testing and customer satisfaction requirements. This certification ensures your Grand Manor roof qualifies for CertainTeed’s best warranty coverage.
Why Experience Matters
Installation takes longer than standard shingles.
The weight and attention to aesthetic quality require care. Each shingle needs positioning that maintains the dimensional appearance while ensuring proper overlap and weather protection.
Rushing produces inferior results. You’re investing in premium shingles. They deserve premium installation quality.
Our 25-year labor warranty backs up this quality commitment. We stand behind your roof for decades.
Warranty Coverage That Protects Your Investment
Grand Manor comes with exceptional warranty protection.
CertainTeed backs these shingles with a lifetime limited warranty covering manufacturing defects. The SureStart PLUS warranty provides 100 percent coverage of material and labor costs for manufacturing defects during the first 10 years, with no depreciation.
What Our Installation Adds
When County Roofing Systems installs your Grand Manor roof, you receive:
50 years of coverage against manufacturing defects
25 years of labor warranty from us
Enhanced wind warranty up to 130 mph
StreakFighter algae resistance warranty for 15 years
This comprehensive coverage protects your investment for decades. The labor warranty is particularly valuable since most manufacturers only cover materials, leaving you to pay for installation labor if issues arise.

Understanding the Investment
Grand Manor represents premium pricing, making it a true premium shingle option for homeowners considering a roof replacement.
Choosing Grand Manor shingles involves an extra cost, as these grand manor luxury shingles are designed for high-end appeal, exceptional durability, and long-term value.
A Grand Manor asphalt shingle roof typically costs around $8.00-$10.00 per square foot, which is approximately double the cost of standard architectural shingles. Installation can also be more expensive due to the complexity of the product and the need for professional roofers with specialized expertise.
Expect to pay 50 to 80 percent more than mid-range architectural shingles for comparable roof area. The pricing reflects both superior materials and expertise required for proper installation.
Why the Premium Makes Sense
Grand Manor’s durability means longer lifespan with fewer repairs.
The enhanced construction withstands weather extremes better than standard products. You’re less likely to need storm damage repairs. The roof simply lasts longer before requiring replacement.
The dramatic improvement in curb appeal adds real value to your home. Real estate professionals consistently note that homes with premium roofing command higher prices and sell faster. You often recover more than the installation cost if you sell within the first 10 to 15 years.
Energy efficiency benefits accumulate over the roof’s lifetime. While the savings won’t offset the entire cost premium, they contribute to overall value.
Financing Makes It Manageable
We offer financing options for qualified customers.
This spreads the investment over time rather than requiring everything upfront. You get the roof you want without immediate budget strain.
Real-world performance matters more than specifications.
How Grand Manor Performs in Real Conditions
We’ve installed and serviced these roofs for decades.
This real-world experience provides valuable insight beyond manufacturer claims.
Coastal Salt Air and Humidity
Grand Manor handles Long Island’s coastal environment well.
We’ve installed these shingles from inland locations to beachfront properties. Coastal installations hold up just as well as those further from the water. Salt air and humidity haven’t shown adverse effects on performance.
Winter Freeze-Thaw Cycles
The weight and construction quality help Grand Manor resist ice dam damage better than lighter shingles.
Granule adhesion remains strong through multiple freeze-thaw cycles. We don’t see the granule loss and brittleness that can plague lower-quality products after harsh winters.
Summer Heat Stress
Grand Manor maintains shape and color integrity during extreme heat.
The shingles don’t show the softening or scuffing issues that can affect lesser products when temperatures soar. The granules stay firmly attached. Colors remain vibrant.
Roofs we installed 15 to 20 years ago still maintain rich, vibrant colors without the fading common in lower-grade shingles.
Storm Performance
Wind events including nor’easters and tropical storm remnants have proven Grand Manor’s wind resistance claims.
The shingles provide exceptional durability and weather resistance, standing up to severe storms, heavy rain, and high winds. When properly installed, these shingles stay put. We’ve seen Grand Manor roofs come through significant storms without losing a single shingle while neighboring homes with standard products suffered damage.
Who should choose Grand Manor?
Is Grand Manor Right for Your Home
Grand Manor makes sense for specific homeowners and situations.
As a high-end roofing material, CertainTeed Grand Manor roofing shingles are designed for those seeking premium quality, exceptional durability, and a luxury appearance that stands out from standard options.
Ideal Candidates
You want your roof to be an architectural feature rather than just functional protection. You appreciate slate aesthetic but need practical benefits of asphalt shingles. You plan to stay in your home long enough to justify the premium investment.
You live in an upscale neighborhood where home appearance affects property values significantly. You value comprehensive warranty coverage and long-term durability. You want top-tier performance to match top-tier aesthetics.
When to Consider Alternatives
Budget is the primary concern and you need the most cost-effective solution. Your home has simple roofline where dimensional quality won’t be fully appreciated.
You plan to sell within the next few years and won’t recoup the premium cost. Your roof structure requires expensive reinforcement to support the additional weight without modifications.
For the right home and homeowner, Grand Manor represents one of the best luxury shingle options available. The combination of proven CertainTeed quality, stunning aesthetics, superior performance, and comprehensive warranty coverage makes these shingles stand out.

Frequently Asked Questions
How long do Grand Manor shingles last?
Grand Manor shingles typically last 30 to 40 years with proper installation and maintenance. Their heavyweight construction and quality materials resist weather damage better than standard shingles. CertainTeed backs them with a lifetime limited warranty, with the first 50 years covered against manufacturing defects.
Can my roof support the weight of Grand Manor shingles?
Most modern residential structures can support Grand Manor’s 425 pounds per square without issue. Older homes or those with prior structural concerns may require evaluation and potentially reinforcement. We assess your structure during the initial inspection and provide honest recommendations.
What's the difference between Grand Manor and standard architectural shingles?
Grand Manor weighs nearly twice as much as standard architectural shingles. The multi-layered construction creates authentic dimensional appearance rather than flat texture. Wind resistance, impact resistance, and thermal performance all exceed standard products. The premium materials and construction translate to longer lifespan.
Does Grand Manor qualify for insurance discounts?
Grand Manor’s Class A fire rating may qualify for insurance discounts. The wind resistance rating can also reduce premiums in coastal areas. Contact your insurance provider to discuss specific discounts available. Documentation of professional installation by a certified contractor helps maximize potential savings.
How does Grand Manor compare to real slate roofing?
Grand Manor replicates slate’s appearance at significantly lower cost and weight. Installation is less complex and expensive. Maintenance requirements are minimal compared to slate. While Grand Manor won’t last the 100-plus years slate can achieve, it provides similar aesthetics with 30 to 40 years of reliable performance at a fraction of the cost.
What maintenance does Grand Manor require?
Grand Manor requires minimal maintenance. Keep gutters clear of debris. Trim overhanging branches to prevent damage. Schedule annual inspections to catch minor issues early. The algae-resistant technology reduces need for roof cleaning. Avoid walking on the roof unnecessarily to prevent granule loss or damage.
