Quick summary

Compare GAF Timberline HDZ, CertainTeed Landmark PRO, and Malarkey Legacy shingles for Chicagoland homes. Wind, hail, warranty, and performance.

Three premium shingle manufacturers, three different approaches, one brutal Illinois climate. Here's how GAF, CertainTeed, and Malarkey compare for Chicagoland homeowners — from a contractor who installs all three.

Wind Resistance

GAF Timberline HDZ: 130 MPH — LayerLock technology creates a mechanical bond without hand-sealing. The strongest wind rating of the three at the standard product level.

CertainTeed Landmark PRO: 110 MPH standard, 130 MPH with Integrity System — Matches GAF only when using the full CertainTeed accessory system. Standard rating is lower.

Malarkey Legacy: 110 MPH — Standard wind resistance. Solid but not class-leading.

Winner: GAF for out-of-the-box wind resistance without requiring additional accessories.

Durability & Flexibility

GAF: Standard oxidized asphalt. Good performance, industry standard formulation.

CertainTeed: Standard oxidized asphalt with enhanced fiberglass mat construction.

Malarkey: Polymer-modified (rubberized) asphalt. More flexible, resists cracking in freeze-thaw cycles, maintains pliability longer.

Winner: Malarkey — the polymer-modified asphalt is a genuine technological advantage for cold climates like Illinois.

Algae Resistance

GAF: StainGuard Plus — copper-containing granules, 25-year algae protection.

CertainTeed: StreakFighter — copper-containing granules, algae resistance included on Landmark PRO and above.

Malarkey: Scotchgard Protector by 3M — industry-leading algae resistance backed by 3M's technology.

Winner: Tie — all three offer effective algae resistance. Malarkey's 3M partnership is a slight marketing edge.

Warranty

GAF: Limited lifetime (materials). Enhanced to Golden Pledge (25-year materials + labor) when installed by a GAF Certified contractor.

CertainTeed: 50-year limited with SureStart PLUS (15 years non-prorated). Enhanced with Integrity Roof System for whole-system coverage.

Malarkey: Limited lifetime on Legacy and Highlander lines. Standard warranty structure.

Winner: CertainTeed for the most comprehensive standard warranty with the Integrity System option.

Aesthetics

All three offer dimensional, high-definition color blends that look excellent on Chicagoland homes. GAF offers the widest color range (20+). CertainTeed's Max Def technology creates the most natural-looking color variation. Malarkey's colors tend to be slightly more muted and natural.

Winner: Subjective — bring samples home and see which looks best against your brick, siding, and trim.

Our Recommendation

There's no wrong answer among these three. For most Illinois homeowners, we recommend based on priorities: GAF Timberline HDZ for maximum wind resistance, CertainTeed Landmark PRO for the strongest warranty system, or Malarkey Legacy for the most durable shingle formulation. We carry all three and can present samples during your free consultation.

What matters as much as the shingle

Shingle brands compete closely, and all the major architectural lines perform well. Roofs fail early for other reasons: flashing that was reused, missing ice barrier at the eaves, too few nails or nails placed too high, and attics that cannot breathe. When you compare estimates, compare the whole system: underlayment, ice and water barrier, starter, ridge cap, flashing and ventilation. A written scope that lists each one tells you more than the brand name on the wrapper.

Hail and wind ratings in plain terms

Impact resistance is rated Class 1 to Class 4, with Class 4 the toughest. In a hail-prone area such as ours, a Class 4 shingle can be worth the extra cost, and some insurers offer a premium discount for it. Wind warranties depend on the shingle being installed with the right number of nails and the matching starter strip. Ask your contractor to show that on the estimate.

Common questions

Are impact-resistant shingles worth it? +
Often, yes. They hold up better to hail, and some insurers discount premiums for a Class 4 roof. Ask your agent before you choose.
What color shingle should I pick? +
Choose one that works with the brick and siding that are staying. Lighter colors run slightly cooler; darker blends hide stains better. We bring sample boards to look at outside.
What does the shingle warranty cover? +
Manufacturer warranties cover defects in the product. Workmanship is covered separately by the installer. Registering the full system can extend the manufacturer coverage.
Which shingle brand is best for Illinois? +
GAF, CertainTeed, Owens Corning and Malarkey all make shingles that perform well here. Installation quality and the full roofing system matter more than the logo.
How long do architectural shingles last? +
Commonly 20 to 30 years in this climate, depending on ventilation, sun exposure and storms.
