Choosing a new roof involves more than selecting a shingle color. The shingles, underlayment, starter strips, leak protection, ventilation and ridge-cap components all work together as part of the roofing system.
GAF offers roofing products ranging from popular architectural shingles to premium and impact-resistant options.
Southern Exterior Construction can help you compare available GAF products based on:
Choose from available architectural shingle styles and colors designed to complement your home's exterior.

A complete roofing system can include shingles, roof deck protection, leak barriers, starter strips, ridge-cap shingles and ventilation components.

North Alabama roofs face intense sun, heat, heavy rain, wind, hail and severe thunderstorms.
GAF's Timberline family provides several roofing options for homeowners looking for architectural shingles with different performance features and price points.
Southern Exterior Construction can inspect your existing roof, discuss your priorities and show you the GAF products currently available for your roofing project.
Timberline HDZ® is GAF's best-selling shingle and combines architectural styling with GAF roofing technologies such as LayerLock® and the StrikeZone® nailing area. GAF
Qualifying Timberline HDZ shingles currently pass the UL 2218 Class 3 Impact-Resistance Test. GAF
Timberline HDZ can be a strong option for North Alabama homeowners looking for a balance of:
Architectural appearance
Class 3 impact resistance on qualifying products
Multiple available colors
GAF roofing-system compatibility
Warranty options
Product availability, colors, classifications and specifications can change. SEC will review the products currently available for your project.
Homeowners interested in increased impact resistance can also consider available GAF Class 4 shingles.
Class 4 is the highest classification under the UL 2218 impact-resistance test.
Two current GAF Class 4 options include:

Timberline ArmorShield II uses SBS-modified asphalt designed to provide increased flexibility and impact resistance. It passes the UL 2218 Class 4 Impact-Resistance Test.

Timberline UHDZ with UltraMat is a premium GAF laminate shingle featuring UltraMat high-performance fiberglass mat technology, a Class 4 impact-resistance rating and GAF's Dual Shadow Line appearance.

Class 3 and Class 4 ratings measure impact resistance — not wind speed.
Class 4 represents a higher UL 2218 impact-resistance classification than Class 3.
For North Alabama homeowners concerned about hail and severe storms, comparing impact-resistant roofing options may be worthwhile.
GAF notes that qualifying Class 3 and Class 4 shingles may qualify for insurance discounts, but availability and savings depend on the insurer and location. Homeowners should verify any potential discount directly with their insurance company.
A simple way to compare three popular GAF choices is:
Class 3 on qualifying products
Popular architectural roofing option
Class 4
SBS-modified asphalt impact-resistant option
Class 4
Premium architectural and impact-resistant option

GAF shingles featuring LayerLock® Technology may qualify for GAF's WindProven™ Limited Wind Warranty with no maximum wind-speed limitation when installed with the required combination of four qualifying GAF accessories. Southern Exterior Construction can explain the available roofing-system components.
