When it comes to roofing, durability isn’t just about longevity—it’s about withstanding the elements. High winds can be particularly destructive, lifting shingles, breaking seals, and compromising your roof’s ability to protect your home. That’s why choosing a roof with a strong wind warranty is essential.
What Is a Wind Warranty?
A wind warranty guarantees that roofing shingles can resist specific wind speeds without damage. Manufacturers like CertainTeed test their products to ensure they meet strict wind resistance standards. If shingles fail due to wind within the warranty period and under proper installation conditions, the manufacturer may cover the cost of repairs or replacement.
Understanding Wind Resistance Ratings
CertainTeed shingles are tested against industry standards to determine their wind resistance. These tests include:
- ASTM D3161 Class F – Ensures shingles can withstand wind speeds up to 110 mph.
- ASTM D7158 Class H – Ensures shingles can resist uplift forces in high-wind conditions.
- UL 2390 Wind Driven Rain Resistance – Evaluates shingles’ ability to prevent water penetration under high winds.
Wind Warranty Coverage: What’s Included?
CertainTeed offers wind warranties on all their shingles, typically including:
- Standard Wind Warranty – Covers wind speeds up to 110 mph.
- Upgraded Wind Warranty – Extends coverage up to 130 mph, provided CertainTeed starter shingles and hip and ridge accessories are used.
- Duration – Most warranties offer 15 years of wind coverage, with lifetime protection on select premium shingles.
Which Roofing Shingles Offer the Best Wind Protection?
If you live in an area prone to strong storms or high winds, consider shingles designed for superior wind resistance. Some of CertainTeed’s top options include:
- Grand Manor® and Belmont® – Luxury shingles with 110 mph standard wind resistance and an upgrade to 130 mph.
- NorthGate® ClimateFlex – Engineered with impact-resistant technology, offering 130 mph extended wind warranty when installed with the proper accessories.
- Presidential Shake TL® – Designed to replicate the look of wood shakes, with wind protection up to 130 mph.
What Voids a Wind Warranty?
Not all wind damage is covered. The manufacturer may deny claims if:
- The shingles were not installed correctly (e.g., incorrect nailing patterns).
- The roof was not maintained properly (e.g., missing flashing or improper ventilation).
- Winds exceeded the warranty limit (e.g., shingles rated for 110 mph fail in a 140 mph storm).
