    Oyster Gray and Pewter Gray: Similarities and Differences

    Both Oyster gray and Pewter gray are two of the most popular roofing shingle colors from the company GAF.

    GAF is a manufacturer of residential and commercial roofing and waterproofing products. The company provides roofing products and solar roofing systems, including roofing shingles, fiber-cement siding, leak barriers, pavement coatings, ductwork, wall nail base insulation, ventilation, vent, and ornamental iron products.

    The flagship and the most popular shingle series of GAF is the Timberline®. It is divided into 8 product lines, namely: Timberline HDZ® Shingles, Timberline® NS Shingles, Timberline® UHD Shingles, Timberline® UHD with Dual Shadow Line Lifetime Roofing Shingles, Timberline® AS II Shingles, Timberline® CS Shingles, Timberline® HDZ™ RS Shingles, and Timberline® HDZ™ RS+ Shingles.

    Oyster gray is only available under the product line Timberline HDZ® Shingles, while the Pewter gray is available in the five product lines: Timberline HDZ® Shingles, Timberline® NS Shingles, Timberline® UHD Shingles, Timberline® UHD with Dual Shadow Line Lifetime Roofing Shingles, and Timberline® AS II Shingles.

    It’s important to note that since the two, Oyster Gray and Pewter Gray, are roofing shingle colors from the Timberline® series, most of the features of both products are identical. But there will also be a notable difference between the two shingle colors in terms of the shingles they are included in, as each has various unique features to one another.

    Oyster Gray vs Pewter Gray: Durability Comparison

    All Timberline® shingles are durable and long-lasting since they all feature Proprietary GAF Dura Grip™ Adhesive that allows the shingles to withstand winds up to 130 mph and resists shingle blow-off by sealing each roofing shingle tightly. This makes both Oyster gray, and Pewter gray provide high durability and performance.

    The only difference is that the shingle line Timberline® AS II, which Pewter Gray is only available in, provides more durability and strength as it features impact-resistant shingles with a Class 4 impact resistance rating. It means the shingles under this line underwent lab testing conditions, proving that they have the highest impact resistance level, withstanding an impact of a 2-inch ball from 20 feet without tearing or splitting.

    Moreover, it features an asphalt formula that provides rubber-like flexibility, allowing the roofing shingles to recover from impact and increase impact resistance.

    Overall, Timberline® shingles are available in the color Pewter gray, which offers more durability.

    Oyster Gray vs Pewter Gray: Gripping Power Comparison

    In terms of gripping power, both Oyster Gray and Pewter Gray are similar because all GAF shingles offer exceptional gripping power for their nailing zone performance, as both feature StrikeZone™ that provides nailing efficiency.

    The only difference is that the shingle line Timberline HDZ® Shingles, which Oyster Gray is only available in, provides more gripping power and strength as it uses GAF LayerLock™ Technology to merge overlapping shingle layers. As a result, it powers the widest nail zone that mechanically strengthens and fuses the bond between the roofing shingles. In addition, it provides up to 99.9% nailing accuracy, ensuring a fast and effortless roofing shingle installation. 

    Overall, the shingle products that Oyster Gray is available in provides more gripping power and nailing zone performance.

    Oyster Gray vs Pewter Gray: Algae and Moisture Resistance Comparison

    Both Oyster Gray and Pewter Gray offer algae-resistant roofing shingles, as the feature StainGuard® Plus™ technology uses specially engineered time-release capsules made of copper microsites in the asphalt shingle granules. These engineered capsules release algae-killing copper up to 10 times slowly over a certain period. 

    This technology helps prevent roof stains while maintaining the lasting life of the shingles. StainGuard® Plus™ technology also prevents the growth of blue-green algae or buildup, which can cause damage if left checked.

    Oyster Gray vs Pewter Gray: Cost Comparison

    Generally, the standard GAF Timberline® price ranges from $75 to $255 per square foot for the shingle alone, while the installation labor fees cost around $130 to $400 per square. Overall, the total installation cost ranges from $6,000 to $10,000, including the shingle materials and other included fees.

    Regarding cost, Oyster Gray and Pewter will only differ depending on your chosen shingle line that these colors are included in.

    Timberline HDZ® Shingles, which Oyster Gray is only available in, range from $90 to $115, while the Timberline® NS Shingles costs around $80 to $105. For the Timberline® UHD Shingles and Timberline® UHD with Dual Shadow Line, the price is about $120 to $150.

    Timberline® AS II Shingles, which Pewter Gray is also available in, cost around $230 to $255, while Timberline® CS Shingles range around $200 to $220.

    Overall, the shingle lines that Pewter Gray is available in, provide a more comprehensive selection of cost choices.

    Oyster Gray vs Pewter Gray: Warranty Comparison

    In terms of warranty, both Oyster Gray and Pewter Gray offer excellent warranty coverage with a wide variety of types to choose from since they come from the same roofing shingle brand, GAF Timberline®.

    GAF offers a Limited Warranty that comes in four types: GAF Shingle & Accessory Limited Warranty, GAF Roofing System Limited Warranty, System Plus Limited Warranty, Silver Pledge Limited Warranty, and Golden Pledge Limited Warranty.

    All four warranty types have coverage of lifetime for the GAF shingles with a length of 40 years. In addition, GAF Shingle & Accessory Limited Warranty and GAF Roofing System Limited Warranty apply for 10 Years of Smart Choice Protection Period coverage, while the System Plus Limited Warranty, Silver Pledge Limited Warranty, and Golden Pledge Limited Warranty feature 50 Years of coverage.

    All four types of the GAF Limited Warranty also cover 10 Years of coverage for the StainGuard-Labeled Shingles or Ridge Cap Shingles (Algae Warranty Term) and 15 years for the Wind Warranty Term.

    Oyster Gray vs Pewter Gray: Final Showdown

    Both Oyster Gray and Pewter Gray are part of GAF’s Black & Gray neutral color palette. These two colors make an excellent backdrop for the exterior house appearance while allowing freedom to explore in combining with other colors. Both of them also make a classic and strong impact on the ambiance.

    The difference between the two colors is that Oyster Gray is lighter in color and has a cooler tone variation. On the other hand, Pewter Gray is darker and has a warmer tone.

    If you prefer the lighter one, Oyster Gray, this shade blends well with shades of grays and cool tones of blues. It also works well with green, cream, white, and ivory color exteriors as it accentuates the siding while adding a soothing and inviting hue.

    If you prefer a darker shade, Pewter Gray, this shade works wonderfully with white, grays, and blues and blends well with contemporary exterior color palettes and earthy colors like yellow, green, gold, or sage. Pewter Gray also works well with brick facades or stucco sidings, providing a dramatic appearance.
