We all want to feel safe and secure under our own roof, knowing it’ll protect us from whatever the weather throws our way. But have we ever stopped to wonder what really stands between us and the elements? The answer often lies in the quality of our shingles—the unsung heroes of our homes.
Choosing the right shingles isn’t just about curb appeal. It’s about peace of mind. With so many options and ratings out there, it’s easy to feel overwhelmed. Let’s break down what shingle quality and ratings actually mean so we can make confident choices for our homes and families.
Understanding Shingle Quality and Ratings
Shingle quality refers to the material durability, manufacturing consistency, and resistance to elements like wind, rain, and hail. National Roofing Contractors Association (NRCA) and ASTM International set key benchmarks for these qualities. Higher-rated shingles usually contain reinforced mats and more asphalt, which increases lifespan and impact resistance.
Ratings systems like UL 2218 for impact resistance and ASTM D7158 for wind ratings use controlled lab tests to evaluate product performance. Class 4 indicates the highest impact resistance—important for zones prone to hail. Wind resistance ratings typically range from 60 mph up to 130 mph, with manufacturers like GAF and CertainTeed specifying their certified limits.
Warranties connect closely to shingle quality, with better products often carrying extended or even lifetime coverage against manufacturing defects. Product labels display both standard and enhanced performance ratings. Comparing these values simplifies your assessment.
If you’re comparing shingle options, keep an eye on both manufacturer and independent third-party ratings. Double-check that published numbers, such as impact class or wind speed, match your region’s weather patterns. This ensures better protection and longer service life for your home.
Key Factors That Determine Shingle Quality
Shingle quality depends on measurable standards and properties designed to withstand real-world conditions. We focus on attributes that directly impact roof performance and lifespan.
Material Composition
Material choices drive shingle quality and application limits. Asphalt shingles dominate the market, often reinforced with fiberglass mats that increase tear and fire resistance. Architectural shingles include extra layers or laminated construction for enhanced durability. Organic mat shingles exist, but fiberglass-based versions account for over 85% of modern residential use in North America, according to the Asphalt Roofing Manufacturers Association. Metal, clay, and composite options are also available, but material ratings vary based on location and exposure.
Durability and Longevity
Durability relates to resistance against cracking, curling, and granule loss. Longevity references the expected functional life span, which for asphalt shingles typically ranges from 15 to 50 years. Most premium products use thicker asphalt, advanced adhesives, and algae-resistant coatings to extend service life. UL and ASTM lab results confirm that shingles meeting Class 4 impact ratings offer greater resistance to hail and debris damage, leading to extended warranties.
Weather Resistance
Weather ratings grade shingles for wind, precipitation, UV rays, and temperature swings. Shingles passing ASTM D3161 or D7158 are rated to withstand wind gusts up to 110 mph (Class F) or 150 mph (Class H). Impact-resistant models certified through UL 2218 perform better in hail-prone regions. In humid climates, look for products with algae- and mold-resistant materials to protect against streaking and moisture-related decay. If local codes demand strict standards, select shingles with relevant certifications listed on the packaging.
Popular Shingle Ratings Explained
Popular shingle ratings simplify your comparison process by grouping products based on performance in key categories. These ratings rely on strict lab standards and real-world tests, giving you a metric-backed way to judge quality.
Impact Resistance Ratings
Impact resistance ratings measure a shingle’s durability against hail, falling branches, and projectiles. Underwriters Laboratories (UL) 2218 is the benchmark test, ranking shingles across four classes (1 to 4). Class 4 holds the highest rating, showing shingles survive 2-inch steel ball drops without cracking.
If you live somewhere prone to hail, such as Colorado or Oklahoma, you might want to pick Class 4 impact-rated shingles for extra peace of mind and sometimes lower insurance premiums. Your home’s long-term protection depends directly on this category.
| UL 2218 Rating | Example Shingle | Impact Resistance Level | Key Use Scenario |
|---|---|---|---|
| Class 1 | Basic 3-tab | Minimal | Mild climates |
| Class 2 | Economy Laminated | Moderate | Occasional hail |
| Class 3 | Mid-tier Architectural | High | Moderate hail or storm risk |
| Class 4 | Premium/Designer | Highest | Frequent severe hail |
Fire Ratings
Fire ratings gauge a shingle’s ability to resist fire spread and ignition. ASTM E108 and UL 790 list three classes: Class A, B, and C. Class A provides the most protection, tested for flame spread, burning brand resistance, and roof deck penetration.
Most modern asphalt shingles meet Class A standards, so you’re getting top-tier defense. If your area faces wildfire risk such as California or the Rocky Mountain region, always select Class A shingles for compliance with insurance and local codes.
Wind Resistance Ratings
Wind resistance ratings indicate how well a shingle stays put during high winds or storms. The ASTM D7158 and D3161 test wind uplift, rating shingles at several speeds, usually 60, 90, or 110 mph under D3161, or Class A, D, and F (up to 150 mph) under D7158.
For coastal locations or regions where hurricanes are a threat, like Florida or the Gulf Coast, consider shingles with the highest wind resistance classification. Matching these ratings with your local weather reduces repair frequency and long-term roof costs.
| Standard | Rating | Simulated Wind Speed | Typical Use Area |
|---|---|---|---|
| ASTM D7158 | Class F | 110-150 mph | Hurricane zones |
| ASTM D3161 | Class A | 60 mph | Low wind areas |
| ASTM D3161 | Class D | 90 mph | Moderate wind regions |
| ASTM D3161 | Class F | 110 mph | High wind/hurricane |
How to Compare Shingle Brands
Comparing shingle brands gives you a structured approach for narrowing your choices based on objective factors. Look at certifications and technical details, as those set brands apart when durability and protection matter most.
Industry Certifications to Look For
Industry certifications verify shingle performance through independent testing. Recognize certifications like UL 2218 for impact resistance, ASTM D7158 for wind uplift, and ASTM E108 or UL 790 for fire ratings since these credentials signal reliable performance. Manufacturers with both NRCA and Miami-Dade County Product Control approvals usually produce shingles tested in harsher climates, which elevates trust in their products.
Reading Manufacturer Specifications
Manufacturer specifications, when reviewed closely, help you identify real product strengths. Compare the listed wind resistance (measured in mph), exposure limits, impact resistance class, and warranty terms. Pay attention to the type of base mat (fiberglass vs. organic), the asphalt weight per square, and the expected lifespan. Check if the specifications reflect certifications from independent labs, as in-product flyers and online technical sheets often list these directly. If you want the right value for your climate, prioritize higher ratings and certifications based on local risks.
Tips for Choosing High-Quality Shingles
Pay attention to certification labels
Industry certifications like UL 2218 (impact resistance) and ASTM D7158 (wind resistance) appear on shingle packaging. These labels confirm shingles passed independent, rigorous testing. Select those that clearly display these certifications, especially if severe weather hits your area often.
Check the material composition
Shingle material decides how long the roof lasts and how well it holds up. Fiberglass-reinforced asphalt shingles resist splitting and moisture damage. Metal or architectural shingles offer greater durability, but often cost more. Review manufacturer specs for details on layer thickness and reinforcing mats before you decide.
Compare warranty coverage
Warranty terms offer clues about overall shingle quality. Longer warranties, such as 30-year or lifetime coverage, tend to indicate higher-grade materials or extra features like algae resistance. Ask about what’s covered and for how long, with a focus on wind, hail, and defect claims.
Review impact and wind ratings
Shingles in hail-prone zones need a UL 2218 Class 3 or 4 rating. Roofs in high-wind regions benefit from a 110+ mph wind warranty. Inspect the technical data section or product literature for these exact figures.
Match the shingle to your local climate
Weather resistance should match your local extremes. Regions with heavy sun demand UV-resistant granules. Coastal and humid climates need algae-resistant coatings. Check for relevant ratings; for example, ASTM D3161 is common for wind-prone regions.
Compare dimensional thickness and weight
Thicker, heavier shingles typically last longer, resist blow-off, and provide more protection. Product data sheets usually list average weight per bundle and overall shingle thickness. Opt for heavier weights for added wind and impact resistance.
Read trusted reviews and consult professionals
Comparing real customer feedback on durability and installation issues helps you spot red flags. Professional roofing contractors can provide local insights and recommend brands proven to perform well in your region.
Confirm color and style options don’t impact performance
A shingle’s pattern, color, or style can affect roof temperature or blend with home design, but performance specs always matter more. Ensure your design choice still offers top-rated quality and protection.
