A residential roof has to do more than complete the exterior of a home. For builders and roofing contractors, it needs to install efficiently, meet project requirements, and support customer confidence. For homeowners, it needs to provide dependable protection, complement the home’s architecture, and deliver lasting value.
GAF residential roofing products bring those priorities together through a coordinated roofing system. Gilcrest/Jewett supplies GAF roofing materials and supports projects with knowledgeable product guidance, material estimating, and dependable delivery throughout central and eastern Iowa.
A Trusted Name in Residential Roofing
GAF is North America’s largest roofing and waterproofing manufacturer, offering products for residential roofs of many styles, performance needs, and budgets. Its lineup includes popular architectural shingles as well as the supporting components needed to build a complete roof system.
That system-based approach matters. A roof is not simply a layer of shingles—it is a group of components designed to help manage water, wind, heat, and moisture from the roof deck to the ridge. Selecting compatible materials can simplify ordering and installation for contractors while helping homeowners better understand what they are getting from their investment.
More Than Shingles: Components of a Complete GAF Roofing System
A properly planned residential roofing system may include:
- Roof deck protection: Adds a protective layer between the roof deck and the shingles while helping manage moisture.
- Leak barriers: Provide added protection in vulnerable areas such as valleys, eaves, rakes, and around penetrations.
- Starter strip shingles: Help secure the roof along the edges and reduce the risk of shingle blow-off.
- Roof shingles: Form the roof’s primary weather-shedding surface and establish much of its finished appearance.
- Hip and ridge cap shingles: Protect roof peaks and hips while giving the roof a coordinated, finished look.
- Attic ventilation: Helps remove excess heat and moisture that can affect comfort and roof performance.
Using components designed to work together can make product selection more straightforward and help crews maintain a consistent installation plan. Certain combinations of qualifying GAF shingles and accessories may also provide access to additional limited warranty options. Contractors and homeowners should always review current GAF warranty terms, product requirements, and installer qualifications before making a final selection.
GAF Timberline HDZ Shingles: A Popular Choice for Residential Projects
Timberline HDZ® is GAF’s best-selling shingle and a strong starting point for many residential roofing conversations. It combines the dimensional appearance homeowners want with installation-focused technology that can benefit professional crews.
LayerLock® Technology powers the wide StrikeZone® nailing area, helping installers place fasteners accurately and consistently. For contractors, that can support a more repeatable installation process. For homeowners, Timberline HDZ shingles offer architectural depth, a choice of color collections, and algae-protection coverage on qualifying products.
When qualifying GAF shingles with LayerLock Technology are installed with the required combination of GAF accessories, the roof may also qualify for the WindProven™ Limited Wind Warranty with no maximum wind-speed limitation. Coverage is subject to specific products, installation requirements, eligibility rules, terms, and restrictions.
Roofing Options for Different Homes, Budgets, and Performance Goals
No single shingle is right for every home. GAF offers choices that allow contractors and homeowners to balance appearance, performance, and budget.
For customers seeking a premium architectural look, Timberline UHDZ® shingles feature a distinctive Dual Shadow Line for greater visual dimension. Qualifying Timberline UHDZ products with UltraMat™ technology achieve a UL 2218 Class 4 impact-resistance rating under controlled laboratory testing. GAF also offers additional architectural, impact-resistant, designer, three-tab, metal, and solar roofing options within its broader residential portfolio.
Product selection and availability may vary by Gilcrest/Jewett location. A local sales professional can help identify available GAF products and compatible system components for a specific project.
Why Contractors and Builders Choose GAF Roofing Products
For roofing professionals, the right product line should support both field performance and the customer experience. GAF residential roofing products offer several practical advantages:
Installation-Focused Product Design
Features such as LayerLock Technology and the StrikeZone nailing area are designed with the installer in mind. Using coordinated system components can also make it easier to build a clear, repeatable roofing specification.
A Complete-System Selling Opportunity
Contractors can help customers understand the role of every layer—from leak barriers and roof deck protection to ventilation and ridge caps. This changes the conversation from simply choosing a shingle to investing in a complete roofing system.
Choices That Make Customer Conversations Easier
Homeowners often begin with color and curb appeal, but they also care about durability, maintenance, budget, and warranty coverage. GAF offers multiple product tiers and styles, giving contractors options for a range of project priorities.
Recognizable Brand and Warranty Options
GAF’s established name and range of limited warranty options can help contractors present a strong value story. Warranty coverage varies by product, system configuration, installation, and contractor eligibility, so requirements should be verified before the project begins.
Local Supply and Jobsite Support
Gilcrest/Jewett helps contractors keep projects moving with material estimates and takeoffs, product recommendations, ordering support, and reliable material delivery. Working with an experienced local supplier can reduce guesswork and help ensure the right products arrive where they are needed.
What GAF Roofing Can Offer Homeowners
Homeowners may not think about every layer of a roofing system, but each component plays a role in protecting the home. Choosing GAF products through Gilcrest/Jewett can provide:
- Curb appeal: Architectural profiles and color options can complement a wide range of home styles.
- Coordinated protection: Shingles, underlayments, starter strips, ridge caps, leak barriers, and ventilation can be planned as one system.
- Options for different priorities: Homeowners can compare product levels based on appearance, performance goals, budget, and available warranty coverage.
- Expert guidance: A roofing contractor and Gilcrest/Jewett sales professional can help narrow the choices and identify the correct components for the project.
How to Choose the Right GAF Roofing System
Before ordering materials, contractors and homeowners should consider:
- Is the project new construction, a full roof replacement, or a repair?
- What are the roof’s pitch, size, design, and ventilation requirements?
- Are there valleys, eaves, penetrations, or other areas that need additional leak protection?
- Which shingle profile and color best complement the home?
- Are impact resistance, algae protection, or specific limited warranty options priorities?
- Which accessories, installation requirements, and contractor credentials are required for the desired warranty coverage?
- What do local building codes and the shingle manufacturer’s installation instructions require?
Making these decisions before work begins can create a clearer material list, reduce delays, and help set expectations with the homeowner.
