    Pros and Cons of Timberline Shingles


    GAF features durable and energy-efficient roofing shingles that use LayerLock™ Technology,  which combines overlapping shingle layers. It also uses another technology, StainGuard Plus™ Time-Release Technology, which helps protect the roofing shingles roof from stains and algae.

    The StainGuard® Plus™ technology utilizes an engineered capsule infused with copper microsites that activates the protection properties of the roof against stain and algae. Their roofing shingles also have a StrikeZone™ nailing area feature, which provides 99.9% nailing accuracy. 

    Their Dura Grip™ sealant is also paired with the StrikeZone™ nailing area, which enhances the strength, durability, and wind uplift performance of the roof. Moreover, Timberline Shingles offer GAF Dura Grip Adhesive for enhanced protection of shingles and helps improve their toughness and durability.

    Timberline Shingles offer custom-designed color options, which provide a modern twist and sophistication to your home. Their roofing shingle lines also provide a wide selection of product lines, colors, and finish options.


    The only drawback of Timberline Shingles is the limited information about their certified local distributors or contractor network, which is essential information because it will provide the customers with a hassle-free buying and installation process.

    Price, Costs, and Hidden Costs of Timberline Shingles 

    You can get the most accurate pricing of Timberline Shingles products through their available distributors, dealers, and local stores authorized by GAF. You can find their certified contractors and roofing companies on GAF’s website.

    The pricing of Timberline Shingles is estimated per square. A square is equivalent to 100 square feet. In general, the price of GAF’s Timberline HDZ Shingles, GAF’s flagship and one of their most popular roofing shingles cost range from $90 to $125.

    For their Timberline UHD Shingles (Ultra High Definition), the cost ranges from $125 – $150. The following pricing applies to materials or products alone. It doesn’t include the other costs to take into account as well, which is the cost of installation and other accessories.

    The costs for accessories typically range from $20 to $30, while the professional installation fees range from $200 to $350.


    The roofing shingles must be stored on leveled and ventilated surface or area with a cover. The area should also have a maintained maximum temperature of about 110°F (43°C). Also, the shingles should not be stored in places with direct exposure to sunlight, near radiators, or steam pipes to prevent unnecessary damages. 

    Prepare the roof deck before installation and ensure that the roof or installation area of the shingles is clean, damage-free, and sturdy. This applies to both new and remodeled roofs.

    The installation of an underlayment underneath the shingles is required by various code organizations since it also has various benefits, such as preventing reaction between asphalt shingles and wood decking and preventing rain from reaching the inside of the house.

    To install an underlayment, GAF recommends using a breather-type underlayment, such as the brands Deck-Armor™ or GAF Shingle-Mate®

    When an underlayment is installed, use a breather-type underlayment, such as GAF Shingle-Mate®, GAF Tiger Paw™ underlayment, or Deck-Armor™. You can also use the underlayment approved by the manufacturer of the shingle you purchased. 

    Moreover, GAF recommends that the fasteners used during installation should only be aluminum or zinc-coated steel, roofing nails measuring 3/8″ to 7/16″ in diameter that is smooth, barbed, or deformed. Before nailing the roofing shingles, measure and fasten a string line first to secure the shingles in place and keep them in a neat row.

    Fasteners should also be able to penetrate the wood or plywood decks at least 3/4″ or 19mm deep. For an enhanced nailing pattern and stronger wind coverage, use at least six nails when installing per shingle.

    Care And Maintenance

    It’s necessary to conduct regular inspections at least twice per year—once during the spring and another one during the fall season to help protect your roofing system. It’s also best to inspect your roof for any damages after a severe weather condition, such as storms, high winds, or hailstorms.

    Always keeping your roof clean and debris-free is also another way of maintaining the high performance of your roofing shingles. Make sure to inspect and remove any debris, such as leaves, rocks, dirt, branches, and other trash that cause blockage.

    Keep the roof area, including the gutters and downspouts, clean and blockage-free to maintain proper drainage. Also, don’t forget to inspect all metal flashings for any sign of rust, damage, deterioration of sealants, or detachments. It includes pitch pockets, counter flashings, and expansion joints.

    GAF recommends that all inspections and maintenance must be done by a professional roofing technician, especially if any parts of the roof need to be repaired or replaced. It’s best to contact a GAF certified contractor or a Master Select™ Roofing Contractor for any repairs, installation, and replacement process.

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

    Both GAF Shingle & Accessory Limited Warranty and GAF Roofing System Limited Warranty feature 10 Years of coverage for the Smart Choice Protection Period, 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 have 10 Years of coverage for the StainGuard-Labeled Shingles or Ridge Cap Shingles (Algae Warranty Term), and 15 years for the Wind Warranty Term.

    The Limited Warranty covers the GAF accessories, including GAF Starter Strip Shingles, GAF Cobra Ventilation Products, GAF Ridge Cap Shingles, GAF Leak Barrier Products, and GAF Roof Deck Protection Products.

    Are Timberline Shingles Worth Buying?
