How Asphalt Shingles Are Made

Asphalt shingles are manufactured through a multi-layer process that creates durable, weather-resistant roofing material.

Manufacturing Process

Step 1: Base Mat Creation

Fiberglass mat creates the foundation — woven glass fibers provide dimensional stability. Older organic mats used cellulose fibers but are rarely used today. The mat provides the structural foundation for the entire shingle.

Step 2: Asphalt Coating

Hot asphalt saturates the mat, creating the primary waterproof barrier. Modified asphalt with polymers improves flexibility and durability. The thickness of this coating determines both shingle quality and expected lifespan.

Step 3: Granule Application

Ceramic-coated mineral granules are pressed into the asphalt surface. These granules provide UV protection, create color and texture, enhance fire resistance, and protect the asphalt from weathering.

Step 4: Backing Material

Sand or mineral backing on the bottom surface prevents shingles from sticking together in bundles and provides texture for proper installation.

Step 5: Adhesive Strips

Factory-applied sealant strips activate with heat and time after installation, bonding shingles together for wind resistance and creating a weather-tight seal.

Quality Indicators

Higher-quality shingles feature thicker asphalt coating, modified asphalt formulations with rubber or polymer additives, multiple layers or laminated construction, larger and more varied granule coverage, enhanced adhesive systems, and stronger backing materials.

Manufacturing standards include ASTM D7158 for wind resistance, ASTM D3462 for tear strength, UL 2218 for impact resistance, and ASTM E108 for fire resistance.

Types of Asphalt Shingles

3-Tab Shingles

3-tab shingles feature single-layer construction with a flat, uniform appearance. Three distinct tabs per shingle give this style its name. These are the lightest weight option at 200–250 pounds per square and remain the most economical choice. Typical dimensions: 12 inches by 36 inches, ⅛ to ¼ inch thick, with 5 inches of exposed area per course.

Expected lifespan: 15–20 years typical, up to 25 years in ideal conditions.

Best for: Budget-conscious projects, rental properties, simple roof designs, and areas with mild weather conditions.

Cost in Colorado Springs: $90–$150 per square installed.

Insurance note: 3-tab shingles have higher depreciation rates, less wind and hail resistance, and are often fully depreciated by year 15–18.

Architectural Shingles

Architectural shingles — also called dimensional shingles — feature multi-layer laminated construction that creates a dimensional, textured appearance. The heavier weight of 300–400 pounds per square makes these the most popular residential choice. Two or more layers bonded together create a random pattern that mimics wood shake roofing.

Expected lifespan: 25–30 years typical, up to 40 years in ideal conditions. Often come with lifetime limited warranties.

Best for: Primary residences, long-term ownership, and most residential applications.

Cost in Colorado Springs: $150–$250 per square installed.

Insurance note: Slower depreciation schedules, better hail and wind resistance, longer replacement cycles, and often carry Class 3 wind ratings.

Premium Designer Shingles

Premium shingles offer the heaviest construction at 400–500+ pounds per square. These luxury shingles simulate slate, tile, or wood shake with maximum dimensional depth and the highest quality materials. Types include luxury architectural shingles, synthetic slate replicas, wood shake replicas, and specialty designer lines.

Expected lifespan: 30–50 years typical, with 50+ years possible with proper maintenance. Often come with transferable warranties.

Best for: High-end homes, historic or custom architecture, severe weather climates, and situations where maximum longevity is desired.

Cost in Colorado Springs: $250–$450+ per square installed.

Insurance note: Minimal depreciation rates, often Class 4 impact rated, may qualify for insurance discounts of 10–30%.

Impact-Resistant Class 4 Shingles

Class 4 shingles pass UL 2218 impact testing, withstanding a 2-inch steel ball dropped from 20 feet. Modified asphalt formulations and reinforced construction provide enhanced hail protection. These shingles are available in most architectural styles and various colors and textures.

Key benefits: Superior hail resistance, insurance premium discounts of 10–30% in Colorado, better long-term performance, and reduced claim frequency.

Cost premium: $10–$30 more per square than standard shingles — a premium that often pays for itself through insurance discounts in hail-prone areas like Colorado Springs.

Components of Asphalt Shingles

Granules

Granules serve multiple critical purposes: UV protection by shielding asphalt from sunlight, color and aesthetic appearance, fire resistance through ceramic coating, algae resistance with copper or zinc treatments, and improved reflectivity for energy efficiency. Granules measure 1–3mm in diameter and account for 40–50% of total shingle weight.

Insurance implications: Granule loss constitutes functional damage, not purely cosmetic damage. Exposed asphalt leads to accelerated UV degradation, and documented granule loss supports insurance claims.

Asphalt Coating

The asphalt coating provides the primary waterproofing layer, bonding the mat and granules together while providing flexibility and elasticity. Asphalt types include straight asphalt, modified asphalt with polymer or rubber additives, oxidized asphalt, and filled asphalt with mineral fillers. Over time, UV exposure hardens asphalt, thermal cycling causes brittleness, and oxidation reduces flexibility — eventually leading to cracking and failure.

Base Mat

Modern shingles use fiberglass mats made from woven or random glass fibers, providing dimensional stability, tear resistance, fire resistance, and no water absorption. Fiberglass is stronger than older organic mats, carries a better fire rating, weighs less, and lasts longer.

Insurance note: Mat damage such as bruising or fractures constitutes functional damage covered by insurance, even if the surface appears intact.

Adhesive Strips

Adhesive strips bond shingles together after installation, providing wind resistance and preventing shingle blow-off. Heat from the sun activates the adhesive over time — proper bonding takes weeks to months. Cold weather may delay bonding, and hand-sealing may be required in winter installations.

Lifespan and Durability

Expected Lifespan by Type

  • 3-Tab Shingles: 15–20 years typical; 12–18 years in Colorado Springs’ climate
  • Architectural Shingles: 25–30 years typical; 20–28 years in Colorado Springs’ climate
  • Premium Shingles: 30–50 years typical; 28–45 years in Colorado Springs’ climate

Factors Affecting Lifespan

Climate and weather impact:

Colorado Springs’ high altitude at 6,035 feet creates intense UV exposure. Temperature extremes range from -20°F to 100°F+. Hail occurs frequently throughout the Front Range. Frequent 40–60 mph winds are common. Heavy snow loads stress shingles. Over 100 freeze-thaw cycles per year damage materials.

Installation quality:

  • Proper nailing requires 6 nails per architectural shingle
  • Correct nail placement — not too high or low
  • Adequate ventilation reduces heat buildup
  • Proper underlayment protects the roof deck
  • Code-compliant methods and manufacturer specifications must be followed

Roof characteristics:

  • Steeper slopes shed water better and last longer
  • South and west exposures age faster due to more sun exposure
  • Poor ventilation shortens lifespan by 30–50%
  • Darker colors absorb more heat and may age slightly faster

Maintenance requirements:

  • Regular debris removal prevents damage
  • Gutter cleaning prevents ice dams and water backup
  • Prompt minor repairs prevent larger problems
  • Annual inspections catch issues early
  • Moss and algae treatment in shaded areas extends life

Colorado Springs Specific Factors

Roofs in Colorado Springs experience shorter lifespans due to intense UV at 6,000+ feet elevation, frequent hail every 1–3 years, extreme temperature swings with 50°F+ daily variation, high winds especially in the foothills, and a dry climate that causes brittleness.

Insurance implications: Roofs are often replaced due to storm damage before reaching wear-out age. Class 4 shingles are increasingly necessary. Regular inspection is important for claim documentation.

Insurance Considerations

Depreciation Schedules

Insurance companies depreciate asphalt shingles based on age and expected lifespan.

  • 3-Tab (20-year life): Depreciates at 5% per year. A 10-year-old roof is 50% depreciated. Full depreciation often occurs by year 18–20.
  • Architectural (30-year life): Depreciates at 3.33% per year. A 10-year-old roof is 33% depreciated. Better claim values than 3-tab.
  • Premium (40–50 year life): Depreciates at 2–2.5% per year. A 10-year-old roof is only 20–25% depreciated. Offers the best claim outcomes.

Example Claim Comparison

Consider a 12-year-old roof with a $20,000 replacement cost:

  • 3-Tab (20-year life): 60% depreciation leaves $8,000 ACV. You pay $12,000 plus your deductible out of pocket.
  • Architectural (30-year life): 40% depreciation leaves $12,000 ACV. You pay $8,000 plus your deductible out of pocket.
  • Premium (40-year life): 30% depreciation leaves $14,000 ACV. You pay $6,000 plus your deductible out of pocket.

Coverage Type

Replacement Cost Value (RCV) pays full replacement cost minus your deductible. Depreciation is recoverable after repairs are complete. This is standard for newer roofs typically under 10–15 years.

Actual Cash Value (ACV) pays depreciated value only with no recoverable depreciation. This is common for older roofs over 15 years and requires significant out-of-pocket payment.

Many insurers switch to ACV-only coverage at 15–20 years. Some require roof replacement before renewal. Requirements vary by carrier and roof type.

Impact Resistance and Discounts

Class 4 impact-resistant shingles earn premium discounts of 10–30% in Colorado. Some carriers may require Class 4 shingles in high-risk areas. Class 3 shingles withstand 90 mph winds while Class 4 shingles handle 110+ mph winds. Manufacturer-certified installation may improve insurance terms.

Identifying Asphalt Shingle Damage

Hail Damage

Look for bruising — dark spots or circular marks on shingles indicate impact. Soft spots when pressed reveal fractured mats. Loss of granules at impact points shows functional damage even if not obvious from the ground. Hail damage shows random distribution across the roof with fresh damage having sharp edges. Ground-level observation may miss damage entirely.

Testing methods: The chalk test involves running chalk across suspected bruises — it catches in fractures. The soft spot test uses gentle pressure to reveal spongy areas.

Corroborating evidence: Look for dents on vents, flashing, and gutters. Check for dings on AC units and vehicles. Review neighbor damage reports and weather service hail reports.

Wind Damage

Common wind damage includes lifted or missing shingles, tabs that are lifted but still attached, entire shingles blown off, shingles creased or folded, and underlayment exposed. Seal failure means shingles are no longer bonded down, making them vulnerable to future wind. Edge damage is most common — rakes and eaves are most vulnerable.

Aging and Wear

Normal aging shows through gradual granule loss, thinning of granule coverage in water runoff paths, and black asphalt showing through worn areas. Curling happens when edges or corners curl upward or cupping occurs in the center of shingles. Cracking develops from brittleness due to UV exposure and thermal cycling — this represents functional failure. Algae and moss create black streaks or green growth and can trap moisture.

Common Questions About Asphalt Shingles

How long do asphalt shingles really last in Colorado Springs?

Expect 12–28 years depending on type and conditions — shorter than national averages due to Colorado’s climate. Intense UV at 6,035 feet means 25% more UV exposure than sea level. Severe hail events happen every 1–3 years. Daily temperature swings of 50°F+ stress materials. Realistic lifespans: 3-tab 12–18 years, architectural 20–28 years, premium and Class 4 28–40 years. Most roofs are replaced due to storm damage (60–70% of replacements) rather than normal wear-out.

Are Class 4 impact-resistant shingles worth it in Colorado Springs?

Yes. Class 4 shingles typically pay for themselves through insurance discounts alone. Additional cost ranges from $1,500–$3,000 more than standard architectural shingles — about 8–12% premium. Insurance savings of 10–30% varying by carrier on average Colorado Springs policies of $2,000–$3,000 per year produce annual savings of $200–$900, with a typical payback period of 2–5 years. Additional benefits include reduced hail damage, fewer claims, better resale value, and longer lifespan. Some carriers now require Class 4 for new policies.

What’s the difference between architectural and dimensional shingles?

They are the same thing — architectural and dimensional are interchangeable terms for laminated, multi-layer shingles. Both refer to multi-layer construction thicker than 3-tab, with textured dimensional appearance, 25–30 year lifespan, and a mid-range price point. Multiple names exist due to marketing by different manufacturers and regional preferences.

Can I mix different types of asphalt shingles on my roof?

Not recommended. Mixing creates performance issues because different weights and thicknesses do not integrate well, varying wind resistance and water-shedding capabilities create problems, and inconsistent aging rates develop. Manufacturer warranties are typically voided by mixing products. Better approaches include replacing entire roof planes if possible, using the same style and color if matching is necessary, and considering full replacement if significant differences exist.

How do I know if my asphalt shingles are failing?

Minor warning signs to monitor include light granule loss in gutters, slight algae staining, and minor edge lifting. Moderate concerns to plan for within 1–2 years include widespread granule loss creating bald spots, curling or cupping edges, cracked or brittle shingles, and multiple missing shingles. Severe problems requiring immediate replacement include extensive granule loss with black asphalt visible, severe curling or cupping, widespread cracking, active leaks, visible daylight through the roof, and sagging areas.
