When it's time for a new roof, one of the first choices you'll face is which shingle brand to use. Walk into any roofing conversation in Connecticut and three names come up consistently: GAF, CertainTeed, and Owens Corning. Together these three brands account for the vast majority of asphalt shingles installed in the Northeast.
The honest truth? All three make excellent products. The differences between them are real but often smaller than marketing materials suggest. What matters most is choosing the right product line within each brand for your home, your budget, and your priorities, and having them installed by a contractor who does it right.
GAF: America's #1 Shingle Brand
GAF is the market leader in North America and for good reason. Their flagship architectural shingle, the Timberline HDZ, is the best-selling shingle in the country. It features LayerLock technology that bonds the shingle tabs together at the factory, delivering Class F wind resistance (up to 130 mph) without requiring additional nailing.
GAF's warranty structure is a genuine differentiator. The Timberline HDZ comes with a Lifetime Limited Warranty on the shingles themselves, plus a 10-year workmanship warranty when installed by a contractor enrolled in GAF's certification program. At Apex, we're enrolled in GAF's contractor program, which means our customers get access to the enhanced warranty coverage.
- Best for: Homeowners who want proven performance, broad color selection, and strong warranty coverage at a competitive price.
- Popular lines: Timberline HDZ (value), Timberline UHDZ (ultra-high definition), Camelot II (designer)
- Price range: Mid-range for HDZ; premium for designer lines
CertainTeed: The Premium Alternative
CertainTeed, owned by Saint-Gobain, is often considered the premium brand among the three, particularly for color depth and dimensional appearance. Their Landmark Pro and Landmark Premium lines are among the most visually rich shingles available in the architectural category, with a heavier weight and thicker profile than many competitors.
CertainTeed's SELECT ShingleMaster certification program is their contractor credential, and it comes with enhanced warranty benefits including a 25-year Surety Protection period on labor and materials. For homeowners who want their roof to be a genuine aesthetic upgrade, not just a functional replacement, CertainTeed's color palette and dimensional look are worth serious consideration.
- Best for: Homeowners who prioritize appearance and are willing to pay a slight premium for richer color and dimension.
- Popular lines: Landmark Pro, Landmark Premium, Belmont (heavyweight architectural)
- Price range: Slightly above GAF Timberline HDZ at comparable grades
Owens Corning: The Wind Resistance Specialist
Owens Corning makes a strong product with some genuinely innovative technology. Their Duration Series shingles feature SureNail Technology, a woven reinforcement strip in the nailing zone that provides exceptional holding power and Class H wind resistance (up to 130 mph) without the need for enhanced nailing patterns.
Owens Corning's colors tend toward the bold and contemporary, making them a popular choice for homeowners who want a modern look. Their Preferred Contractor program provides access to enhanced warranty coverage, including a 10-year workmanship warranty period.
- Best for: Homeowners in exposed locations with high wind risk, or those who prefer a contemporary color palette.
- Popular lines: Duration, Duration Storm (enhanced impact resistance), Berkshire (designer)
- Price range: Comparable to GAF Timberline HDZ; premium lines priced similarly to CertainTeed
What Actually Matters for Connecticut Homes
Given Connecticut's climate, wet winters, significant snow loads, ice dam risk, and humid summers, there are a few product characteristics worth prioritizing regardless of brand:
- Impact resistance rating. Class 4 impact-resistant shingles can qualify for homeowner's insurance discounts in some cases and hold up better to hail. Worth asking about if you're in an exposed area.
- Algae resistance. Connecticut's humidity makes algae streaking (those dark stains on north-facing slopes) a real issue. All three brands offer algae-resistant options, look for "AR" or "Algae Resistant" in the product name.
- Wind warranty. Standard shingles are typically warranted to 60–110 mph. In exposed hilltop locations common in Ridgefield and Wilton, a Class F or H wind rating gives real peace of mind.
Our Recommendation
We install all three brands and genuinely recommend each for different situations. If we had to pick a default for a typical Westport or Darien colonial, we'd start the conversation with GAF Timberline HDZ, it's the best combination of performance, warranty, availability, and price for most homes. If appearance is the priority, we'd look closely at CertainTeed Landmark Premium. For exposed sites, Owens Corning Duration with SureNail gets serious consideration.
When we come out for your estimate, we'll walk you through the options that make sense for your specific home, style, and budget. There's no right answer that applies to every house, but there is a right answer for yours.
