CertainTeed Landmark Shingles In Atlanta Weather
Atlanta’s climate presents unique challenges for roofing materials. With hot, humid summers, occasional winter freezes, and everything from thunderstorms to the occasional tropical storm remnant, your roof needs to withstand diverse weather conditions. CertainTeed Landmark shingles have become a popular choice for Atlanta homeowners seeking durability without sacrificing aesthetic appeal. This article examines how these premium asphalt shingles perform in Atlanta’s specific climate conditions.
Understanding Atlanta’s Weather Challenges
Before investing in any roofing material, it’s important to understand the specific weather conditions it will face in Atlanta:
- Summer Heat and Humidity: Atlanta regularly experiences temperatures above 90°F with high humidity levels that can accelerate shingle deterioration
- Sudden Thunderstorms: Frequent summer thunderstorms bring heavy rain, occasional hail, and strong winds
- UV Exposure: Significant sun exposure throughout the year can fade and damage lesser-quality shingles
- Winter Freeze-Thaw Cycles: While not as extreme as northern climates, Atlanta does experience occasional freezing temperatures and winter precipitation
- Tropical Storm Remnants: Hurricane season can bring tropical storm systems with sustained heavy rains and winds
CertainTeed Landmark Shingles: Key Features for Atlanta Homes
CertainTeed’s Landmark architectural shingles offer several features particularly beneficial for Atlanta’s climate conditions:
Advanced Weather Protection
CertainTeed Landmark shingles are engineered with a dual-layer design that provides extra thickness and dimensional appearance. This construction creates superior weather resistance against Atlanta’s diverse conditions. The shingles feature CertainTeed’s proprietary weather-resistant technology that helps them maintain structural integrity through seasonal temperature fluctuations.
Heat and UV Resistance
Atlanta’s summers can be brutal on roofing materials. Landmark shingles incorporate specialized granules that reflect solar heat and UV rays, helping to:
- Reduce heat absorption into the home
- Minimize thermal expansion and contraction
- Maintain color integrity despite years of sun exposure
- Potentially lower cooling costs during hot summer months
Wind Resistance Capabilities
Thunderstorms and tropical weather systems can bring significant wind to the Atlanta area. Landmark shingles feature:
- Wind resistance rating up to 110 mph with standard installation
- Up to 130 mph wind resistance with enhanced installation methods
- CertainTeed’s QuadraBond adhesive system that creates a strong seal between shingle layers
Algae Resistance
Atlanta’s humidity creates perfect conditions for algae growth on roofing materials, which can cause unsightly black streaking. Landmark shingles include copper-infused granules that prevent algae growth, helping maintain your roof’s appearance for years without the black streaks common on older roofs in the area.
Landmark Shingle Options for Atlanta Homes
CertainTeed offers several Landmark shingle variations, each with specific benefits for Atlanta homeowners:
| Shingle Type | Key Features | Best For |
|---|---|---|
| Landmark | Dual-layer protection, good wind resistance, 10-year algae resistance | Budget-conscious homeowners seeking reliable protection |
| Landmark Pro | Enhanced color options, stronger wind resistance, Max Def color technology | Homeowners wanting upgraded aesthetics and performance |
| Landmark Premium | Premium weight, enhanced warranty, superior impact resistance | Luxury homes and areas prone to severe weather |
| NorthGate ClimateFlex | Enhanced flexibility in cold weather, Class 4 impact resistance | Areas of Atlanta that experience occasional hail or freezing conditions |
NorthGate ClimateFlex: A Specialized Option for Atlanta
While standard Landmark shingles perform well in Atlanta, the NorthGate ClimateFlex variation offers additional benefits for homeowners concerned about extreme weather variations:
Enhanced Flexibility
The ClimateFlex technology allows these shingles to remain flexible even during cold weather installation or winter temperature drops. This flexibility helps prevent cracking during Atlanta’s occasional winter freezes and improves installation quality year-round.
Superior Impact Resistance
With a Class 4 impact resistance rating (the highest available), NorthGate ClimateFlex shingles offer exceptional protection against hail damage. While severe hail is not an everyday occurrence in Atlanta, when it does strike, these shingles provide significantly better protection than standard options.
Insurance Benefits
Some insurance companies offer premium discounts for homes with Class 4 impact-resistant roofing. Atlanta homeowners may want to check with their insurance provider about potential savings with NorthGate ClimateFlex installation.
Performance in Atlanta’s Seasonal Weather
How do CertainTeed Landmark shingles handle Atlanta’s seasonal weather patterns?
Summer Performance
During Atlanta’s hot, humid summers, Landmark shingles demonstrate excellent heat resistance. Their specialized granules reflect solar heat rather than absorbing it, helping maintain more consistent attic temperatures. This can contribute to energy efficiency during cooling season. The algae-resistant properties are particularly valuable during humid summer months when moisture-loving algae would typically thrive on roofing surfaces.
Storm Season Durability
Atlanta’s frequent thunderstorms put roofing materials to the test. Landmark shingles’ dual-layer construction and strong adhesive system help them withstand the heavy rains and gusty winds common during Georgia storm seasons. The secure sealing between shingles prevents wind uplift that can damage lesser products.
Winter Weather Protection
Though Atlanta winters are milder than northern regions, the occasional freeze-thaw cycles can stress roofing materials. Landmark shingles maintain flexibility during temperature fluctuations, reducing the risk of cracking or splitting during winter cold snaps. For areas of Atlanta that experience more frequent freezing, the NorthGate ClimateFlex variation offers enhanced cold-weather performance.
Color Retention in Atlanta’s Sun
CertainTeed’s Landmark Pro and Premium lines feature Max Def colors that maintain their vibrancy despite years of sun exposure. This is particularly important in Atlanta, where significant sun exposure throughout the year can quickly fade lesser shingles. The specialized color granules resist UV degradation, helping your roof maintain its aesthetic appeal for years longer than standard shingles.
Installation Considerations for Atlanta
Proper installation is crucial for maximizing the performance of CertainTeed Landmark shingles in Atlanta’s climate:
Timing Matters
While Landmark shingles can be installed year-round in Atlanta, scheduling installation during mild spring or fall weather allows for optimal adhesive sealing. The ideal installation temperature range is between 40°F and 85°F.
Ventilation Requirements
Atlanta’s heat and humidity make proper attic ventilation essential. CertainTeed recommends a balanced ventilation system with intake vents at the eaves and exhaust vents near the ridge. This helps prevent heat buildup that can reduce shingle lifespan and increases overall energy efficiency.
Certified Contractor Selection
CertainTeed offers certification programs for contractors. Selecting a CertainTeed ShingleMaster™ or SELECT ShingleMaster™ contractor in the Atlanta area ensures your installation meets manufacturer specifications and qualifies for the strongest warranty protection.
Warranty Protection for Atlanta Homeowners
CertainTeed offers robust warranty coverage for Landmark shingles, with considerations particularly valuable for Atlanta’s weather conditions:
- Lifetime Limited Warranty: Coverage against manufacturing defects for the lifetime of the original homeowner
- 10-15 Year SureStart™ Protection: 100% replacement coverage (including labor) during the initial warranty period
- Wind Warranty: Protection against wind damage up to 110-130 mph depending on installation method
- Algae Resistance Warranty: 10-15 year coverage against algae staining (particularly valuable in humid Atlanta)
- Transferability: Limited warranty transferability to a second owner, maintaining home value
Cost Considerations for Atlanta Installations
While pricing varies based on specific home requirements, contractor selection, and current material costs, Atlanta homeowners can expect approximate price ranges for CertainTeed Landmark products:
| Shingle Type | Approximate Cost Range (Per Square*) | Value Considerations |
|---|---|---|
| Landmark | $90-120 | Good balance of performance and affordability |
| Landmark Pro | $110-140 | Enhanced color technology and performance |
| Landmark Premium | $130-160 | Premium weight and extended warranty benefits |
| NorthGate ClimateFlex | $140-170 | Class 4 impact resistance, potential insurance savings |
*One square covers 100 square feet of roof area. Installation costs additional.
Comparing CertainTeed to Other Brands in Atlanta
When evaluating roofing options for Atlanta homes, homeowners often compare CertainTeed Landmark shingles with other major brands:
CertainTeed vs. GAF
Both manufacturers offer quality architectural shingles suitable for Atlanta weather. CertainTeed Landmark shingles typically feature slightly heavier weight than comparable GAF products, potentially offering enhanced durability. CertainTeed’s warranty coverage is generally considered among the strongest in the industry.
CertainTeed vs. Owens Corning
Owens Corning Duration shingles compete directly with Landmark products. CertainTeed Landmark shingles often receive praise for superior color options and aesthetic appeal, while both provide good weather resistance for Atlanta conditions.
CertainTeed vs. Atlas and Malarkey
While less common in some markets, Atlas and Malarkey offer quality alternatives. Malarkey shingles feature rubber-modified asphalt that provides excellent flexibility in changing temperatures. CertainTeed’s advantage comes from its established reputation and widespread contractor familiarity in the Atlanta market.
Troubleshooting Common Issues in Atlanta Climate
Even with quality shingles, Atlanta’s weather can occasionally cause issues. Here are solutions for common concerns:
Addressing Moisture Buildup
Atlanta’s humidity can create condensation issues in poorly ventilated attics. If you notice moisture problems after Landmark shingle installation:
- Verify proper attic ventilation ratio (1:300 minimum)
- Check for blocked soffit vents
- Consider adding ridge vents if insufficient exhaust ventilation exists

- Granule accumulation in gutters (some initial granule loss is normal)
- Debris impact damage
Preventing Algae Recurrence
If algae appears despite algae-resistant shingles:
- Clear overhanging branches to increase sun exposure
- Keep gutters clean to prevent standing water
- Consult a professional about gentle cleaning methods if necessary
