Understanding the CertainTeed Landmark Shingle Line
The CertainTeed Landmark line is composed of multiple product variants, each designed with unique features and capabilities. While all share core characteristics such as a fiberglass base, asphalt coating, and mineral granules, the differences between Landmark, Landmark PRO, Landmark Premium, and Landmark TL make them suitable for varying environmental conditions and performance demands.
The base model CertainTeed Landmark is engineered to offer a balance of durability and aesthetic appeal, with enhanced resistance to fire, algae, and wind. Users in moderate climates may find this product sufficient for their roofing needs. Landmark PRO, the next tier in performance, enhances impact resistance to help protect homes in areas prone to hail. This makes it a more robust choice for regions frequently affected by severe weather.
CertainTeed Landmark Premium provides an even higher level of protection against damage, with added resistance to wind and wind-driven rain. It is especially suited for high-wind areas and is covered by certain CertainTeed warranties that extend up to 130 mph in wind resistance when installed with a complete CertainTeed roofing system. Lastly, Landmark TL (Timberline Landscape) appears to share some traits with the other models but may offer distinct design or functionality—exact data on these specifics remain unclear from the source material.
Each CertainTeed Landmark variant also includes a range of color options and may incorporate proprietary technologies like StreakFighter® for algae resistance and NailTrak® for streamlined installation. These features, while beneficial, require proper installation to ensure optimal performance. The next section details how to prepare for the installation process and includes specific guidance on underlayment and fastening requirements.
Preparing for Installation
Proper preparation is a crucial step in ensuring the integrity and longevity of a CertainTeed Landmark roofing system. Before installing the shingles, it is essential to evaluate and address the existing roof structure, particularly when a tear-off is deemed necessary. The installation guidelines require removing all existing shingles and underlayment when applying a new roofing system, as debris or previous underlayments can compromise performance.
The underlayment serves as a critical barrier against moisture and is a foundational component for proper shingle adhesion and sealing. For CertainTeed Landmark shingles, the recommended underlayment is a 15-pound asphalt-saturated felt, with the stipulation that it must meet ASTM D226 specifications. While heavier underlayment options may be considered for high-wind conditions, the manufacturer explicitly confirms the 15-pound felt as compliant and suitable for all variants. Correct application of this underlayment ensures that the roofing system remains protected against weather infiltration.
Another essential preparation step is the verification of roof slope and venting. The CertainTeed Landmark installation instructions state that these shingles are suitable for roof slopes ranging from 4:12 to any steeper incline. However, the product is not recommended for low-slope applications below 4:12. Furthermore, adequate venting must be maintained according to standard building codes and local requirements. Proper ventilation prevents the buildup of moisture and helps regulate attic temperature, both of which are critical to the roof's long-term performance.
The final stage of preparation involves identifying the starting point for installation. According to the manufacturer's instructions, shingle installation should begin at the eaves or bottom edge of the roof slope. This layout establishes a foundational base from which the rest of the roof surface can be methodically and sequentially built. It is also important to account for thermal expansion and contraction by avoiding the use of staples or tacks that could restrict movement, particularly in varying temperature conditions. Using the correct fasteners, as outlined in the following section, is the next critical step.
Installation Fasteners and Nail Specifications
The appropriate selection and application of fasteners play a critical role in ensuring the longevity and performance of CertainTeed Landmark shingles. According to the manufacturer's guidelines, all shingles in the Landmark line must be secured using roofing nails that meet or exceed the specifications outlined in ASTM D1581 and ASTM D4801. These standards define the mechanical properties and performance characteristics that the nails must fulfill to ensure a secure and durable attachment.
The recommended nail type for CertainTeed Landmark is a 6d common or 8d box nail. These nails are widely used in roofing applications for their ability to maintain a firm hold under various conditions. The installation instructions emphasize that nails must be driven ½ inch into the wood sheathing or collar, with an additional penetration of the head approximately ⅛ of an inch to prevent exposure and the risk of corrosion over time. The exact pressure and depth are critical to preventing uplift or loosening in high-wind environments.
The fastening method also plays a key role in reducing wind uplift and ensuring the shingles remain securely in place. The CertainTeed manual specifies that nails should be placed within the nailing zone of the shingle, which is typically marked by nail slots or dimples to guide installers. Nailing too close to the edge can compromise the structural integrity of the shingle, while nailing too far away may reduce effectiveness against wind forces. These guidelines must be consistently followed to maintain the recommended wind uplift ratings and to comply with regional building codes.
CertainTeed Landmark Premium, in particular, features enhanced protection against strong wind forces, but even with this variant, the correct fastening technique is essential. The installation instructions emphasize that these shingles are especially reliant on proper fastening to maintain warranties covering wind conditions up to 130 mph when installed as part of a full CertainTeed roofing system. The same nail specifications and placement guidelines apply to Landmark PRO and Landmark TL variants, with the key difference being the increased emphasis on impact and wind resistance for specific models.
Installation Techniques and Layout Strategies
Once fasteners have been properly selected and prepared, the actual installation of CertainTeed Landmark shingles must adhere to carefully outlined techniques and layout strategies to ensure both aesthetic appeal and optimal functionality. The installation process is step-specific, with guidance for alignment, pattern, and securing the shingles in a consistent and uniform manner.
The installation starts at the lowest edge of the roof and progresses upward, with each course of shingles aligned to an already measured line of 8 feet or 9 feet. Proper alignment is essential not only for appearance but for ensuring structural continuity and preventing water infiltration through improper coverage. The first row of shingles is positioned directly on the underlayment, with the rough-cut tab (R3 tab) being trimmed using a utility knife or circular saw if needed to conform to the roof edge. As the installation progresses, each subsequent row is offset from the prior one by following a standard layout of either a 12-inch tab overlap or a full tab overlap, as outlined in the CertainTeed instructions.
The nailing pattern also plays a critical role in distribution and wind resistance, with recommended placements at 6-inch intervals on center for both the headlap and the butt lap of each shingle. This ensures that no section of the roof is under-fastened, which could lead to uplift issues, especially in high-wind conditions. The CertainTeed installation manual emphasizes the importance of verifying that all nail heads are countersunk and free of protrusions to prevent damage and maintain the seamless appearance of the roofing surface.
For the CertainTeed Landmark TL variant, an additional consideration is the use of the NailTrak® design, which is a proprietary feature intended to simplify and improve the alignment of shingles during installation. This design assists in keeping nail placement centered and consistent, reducing the risk of misalignment or incorrect fastener application. Though specific details about this feature are less elaborately described in the source materials, the presence of NailTrak® in the Landmark TL models indicates a focus on both installation efficiency and long-term structural integrity.
All CertainTeed Landmark variants, including the base model, require careful attention to the positioning of tabs at each overlap. A staggered pattern is key to maintaining a visually appealing finish and ensuring that water and weather elements are appropriately channeled away from the roof surface. The installation instructions highlight the avoidance of unattractive joint patterns by ensuring that the end tabs of one course do not consistently meet or align with those of the next. This technique prevents visible seams, which could otherwise result in a less seamless aesthetic and potential weak points in the shingle layer.
Handling Gables and Ridge Cuts
Certain roof structures with gable ends and ridge lines require special attention during the installation of CertainTeed Landmark shingles to ensure secure and weather-resistant coverage. These areas often involve irregular shapes and curved lines, and cutting shingles to fit these sections must be done with precision to maintain the product's performance and appearance.
Gable end shingles must be cut to match the peak or side lap on each end. The CertainTeed installation instructions specify that one half of the rough-cut tab (R3 tab) should be removed from each gable shingle to allow for even placement over the gable lines. This tab typically extends around the edge and, when removed, ensures that the gable shingles align with adjacent sections without an uneven overhang or improper fit. Each gable shingle also requires proper nailing within the designated nailing zone.
The installation of ridge shingles is an essential step that secures the top edge of the roof. These shingles must be cut perpendicular to the ridge line in a fan-like shape so that each tab fits seamlessly into the adjacent row of standard shingles. Once positioned, the ridge shingles overlap each other by one-half of an inch, forming a continuous, watertight barrier at the roofline. Proper fastening and cutting here ensures that the upper section of the roof is fully protected against wind and water infiltration.
It is important to note that these installation techniques are consistent across all CertainTeed Landmark variants, including the Landmark PRO, Landmark Premium, and Landmark TL models. The key difference lies in the degree of expected performance under extreme weather conditions, particularly for the Premium and PRO variants. Regardless of the model being used, precise installation around gables and ridges is necessary to maintain the structural integrity of the roofing system and to ensure that the manufacturer’s warranty remains valid. Failure to properly address these areas during installation can lead to water damage, wind uplift issues, or aesthetic irregularities.
Warranties and Performance Specifications
CertainTeed Landmark shingles are backed by warranties that reflect their engineered performance characteristics. The base CertainTeed Landmark model includes a limited warranty, typically covering manufacturing defects and issues related to premature failure due to material breakdown under normal conditions. These warranties may vary by regional installer or variant within the Landmark line, and exact coverage terms are often dependent on the installer's SELECT ShingleMaster status and the complete installation of the rood system.
Landmark PRO, as an enhanced variant, is engineered for additional impact resistance, making it suitable for regions prone to hail damage. The warranty associated with PRO models is likely to emphasize this resistance, though specific details are absent from the provided documentation. Still, the product's specifications suggest it can better withstand harsh conditions typically unaccounted for in a standard shingle.
CertainTeed Landmark Premium is the highest-performing option, engineered to withstand wind speeds up to 110 mph. However, the manufacturer notes that with the full installation of a CertainTeed roofing system—including appropriate underlayment, shingle attachment methods, and venting—the wind resistance warranty can be extended to up to 130 mph. This level of protection makes Premium an essential option for homeowners in coastal or high-wind regions where roofs are frequently exposed to severe weather.
All CertainTeed Landmark models feature StreakFighter® technology, a proprietary anti-algae solution formulated in the shingle’s mineral granules. This protection, while not explicitly included in warranty coverage like wind or hail resistance, contributes to the longevity of the roofing system by preventing unsightly algae buildup on the surface. The absence of visible streaking not only enhances the visual appeal of the roof but also reduces the need for maintenance and cleaning.
Installation methods significantly influence the validity of these warranties. For example, proper nailing and alignment must be performed to ensure CertainTeed’s wind resistance ratings remain intact. Similarly, full adherence to CertainTeed's installation manual is a prerequisite for maintaining a Premium model's extended warranty coverage for wind resistance. Regional codes and installer certification, such as SELECT ShingleMaster credentials, are also key factors in warranty validation and claim eligibility.
Safety and Maintenance Considerations
Proper safety practices and ongoing maintenance are essential components in the long-term performance and durability of CertainTeed Landmark shingles. While the product line is engineered for resilience against wind, fire, and impact, external factors like debris accumulation or long-term corrosion can affect its effectiveness over time.
One of the primary safety considerations is the use of correct installation gear and procedures. Installers must adhere to OSHA guidelines or local labor safety requirements when working on roofs. CertainTeed emphasizes the use of fall protection systems and non-slip footwear to ensure that all personnel involved are adequately secured from potential hazards. Correct installation techniques, including proper nail placement and nailing zone adherence, also serve as passive safety measures that prevent structural weakening or premature shingle failure.
Maintenance is less intensive for CertainTeed Landmark shingles due to their engineered durability, but regular inspections and cleaning can prolong the roof’s life. For instance, the StreakFighter® technology reduces but does not entirely prevent algae buildup, particularly in areas with high humidity or frequent moisture exposure. If necessary, cleaning the roof with a mild biodegradable detergent should be sufficient to remove buildup without damaging the asphalt-coated surface. It is generally advised to avoid pressure washing and abrasive cleaning methods that could dislodge granules or damage the protective layer of the shingle.
Periodic inspection of fasteners and nails is also recommended, especially if the roof has withstood severe weather conditions. If any nails are found protruding, loose, or if a shingle is showing signs of wear, they should be replaced as needed. In the case of CertainTeed Landmark Premium or Landmark PRO, maintaining the full integrity of the roofing system—such as keeping venting clear and ensuring all shingles are correctly aligned—is critical in upholding the extended warranty protections for wind resistance and damage prevention.
Lastly, the use of recommended underlayment, such as a 15-pound asphalt-saturated felt, serves as a secondary safety and weather barrier. Over time, exposure to UV rays, thermal shifts, and moisture can weaken any underlayment, but with proper application and installation, its protective function is preserved for the life of the roof.
