Asphalt Shingle Installation
American Shingle Co. connects homeowners nationwide with licensed and insured roofing specialists dedicated to precision asphalt shingle installation. Our partner network provides prompt local coordination with typical contractor response times of 30 to 90 minutes — delivering code-compliant installation, expert deck and ventilation integration, and manufacturer-backed warranties.
Understanding Asphalt Shingle Installation & Replacement
When planning a steep-slope residential roofing project, asphalt shingle installation encompasses both new construction installation and the complete tear-off and replacement of aging, weathered shingles down to the structural roof decking.
Our nationwide contractor referral network connects property owners with independent, verified roofing professionals who specialize in asphalt systems. From architectural layout and proper ventilation integration to code-compliant fastening patterns, every project is executed to deliver optimal weatherproofing and aesthetic curb appeal.
The 5-Step Professional Installation Process
A certified residential installation follows a rigorous engineering sequence to protect your home's building envelope:
- Complete Tear-Off & Deck Inspection: Removal of all existing roofing layers down to bare plywood or OSB sheathing. Damaged, delaminated, or rotted decking boards are replaced with new APA-rated sheathing.
- Eaves & Valley Water Barrier Installation: Application of self-adhering ice-and-water membranes along critical leak zones, including eaves, valleys, rakes, and chimney saddles.
- Synthetic Underlayment & Metal Drip Edge: High-tear-strength synthetic underlayment is rolled horizontally across the entire deck, complemented by corrosion-resistant metal drip edge installed along all perimeter roof edges.
- Precision Shingle Application: Shingles are installed using manufacturer-specified nail schedules (typically 4 to 6 fasteners per shingle) to ensure wind resistance compliance up to Up to 130 MPH (ASTM D7158 Class H).
- Ridge Ventilation & Magnetic Cleanup: Continuous ridge exhaust vents and matching hip/ridge cap shingles are secured, followed by multiple rolling magnetic sweeps across lawns, driveways, and landscaping to collect all loose nails.
Building Code & Fire Safety Compliance
Asphalt Shingle Installation must meet strict building standards under the International Residential Code (IRC Chapter 9). With a certified fire rating of Class A (UL 790 standard) and an impact rating of Class 3 to Class 4 (UL 2218), this system provides dependable defense against windborne embers, hail strikes, and severe weather events.
Independent contractors in our network pull required municipal building permits, coordinate mid-deck or final building inspections, and ensure all installations adhere to local climate amendments.

Pros and Cons of Asphalt Shingles
Advantages
- Lowest upfront material and labor investment of all steep-slope roofing systems
- Widespread contractor familiarity ensures prompt installation and competitive labor rates
- Architectural multi-layer laminated dimensional profiles provide depth and shadow lines
- Available with algae-resistant Scotchgard or copper granules to prevent dark streaks
- Class 4 impact-resistant options qualify for homeowner insurance premium discounts
Considerations & Drawbacks
- Shorter total service life compared to composite, metal, or natural slate
- Vulnerable to granule erosion under extreme thermal cycling and intense UV exposure
- Requires adequate attic soffit and ridge ventilation to prevent blistering
Comparing Asphalt to Alternative Shingle Materials
Before committing to an installation, explore how Asphalt compares to popular alternative roofing choices:
Composite Shingles
Composite offers double the lifespan (50 years) and superior impact resistance at roughly 2x the material investment.
Metal Shingles
Metal shingles provide 50+ year longevity and superior hail resistance, eliminating granule shedding entirely.

What is the difference between 3-tab and architectural asphalt shingles?
Architectural (dimensional) shingles feature two bonded fiberglass layers, providing a dimensional wood-shake appearance, 110-130 mph wind ratings, and 30-year warranties. Traditional 3-tab shingles are single-layer flat strips with lower 60-70 mph wind ratings and a shorter 20-year expected service life.
How long does a complete asphalt shingle installation take?
For an average 2,000 to 2,500 square foot single-family home, a professional roofing crew typically completes tear-off, underlayment installation, shingling, flashing, and magnetic cleanup in 1 to 2 business days, weather permitting.
Can new asphalt shingles be installed over an existing roof layer?
While building codes (IRC Section R908.3) permit up to two layers of asphalt shingles in many jurisdictions, a complete tear-off is recommended to inspect the underlying roof deck for rotted sheathing, replace flashing, and ensure full manufacturer warranty coverage.
What wind rating do architectural asphalt shingles carry?
Standard architectural shingles carry ASTM D7158 Class H wind ratings, certifying resistance to winds up to 150 mph when installed with a 6-nail fastening pattern and approved starter strips along eaves and rakes.
