  • What Is Asphalt Shingle Installation and How Does It Work?

    Asphalt shingles are the most common roofing material in the United States, covering an estimated 80% of American homes. But what exactly is asphalt shingle installation, and how does the process work? Understanding the fundamentals helps you make informed decisions about your roof.

    What Are Asphalt Shingles? An asphalt shingle is a roofing material made from a fiberglass or organic mat, coated with asphalt, and topped with mineral granules. The granules protect the asphalt from UV rays and provide color. The asphalt provides waterproofing. The fiberglass mat gives the shingle its strength and fire resistance. This construction makes asphalt shingles durable, affordable, and relatively easy to install.

    How Does Installation Work? Installation begins with tearing off the old roof (if applicable) down to the roof deck. The deck is inspected for damage and repaired. Then, a waterproof underlayment is laid over the deck. Metal flashing is installed at critical transition points—chimneys, skylights, valleys, and vents—to prevent leaks. Finally, the shingles are nailed down in overlapping rows, starting from the bottom edge and working upward. Each row overlaps the one below, creating a water‑shedding barrier.

    Why Installation Quality Matters: Even the best shingles fail prematurely if installed incorrectly. Poor nailing, inadequate ventilation, or skipped underlayment can lead to leaks and reduced lifespan. For the costs involved, see our asphalt shingle installation cost guide.

    How Long Should It Last? A properly installed asphalt shingle roof should last 20–30 years or more. Learn about expected lifespan and warranty in our article on how long asphalt shingles last.

  • How to Choose a Licensed Asphalt Shingle Installer

    Your asphalt shingle roof is only as good as the contractor who installs it. Choosing the right licensed asphalt shingle installer ensures quality workmanship, proper permits, and warranty protection. Here’s how to find a contractor you can trust.

    1. Verify Licensing and Insurance. Always confirm the contractor is licensed in your state. Ask for the license number and verify it with your state’s licensing board. They must carry general liability insurance and workers’ compensation. This protects you from liability if a worker is injured or damage occurs.

    2. Look for Local Experience. Choose a contractor with a physical address and a proven track record in your area. Local contractors understand local codes, weather patterns, and permit requirements. Ask: “How many asphalt shingle roofs have you installed in this area?”

    3. Get Multiple Written Estimates. Obtain at least three detailed quotes. Each should break down materials, labor, tear‑off, disposal, and any additional work. For typical costs, see asphalt shingle installation cost.

    4. Check References and Reviews. Ask for references from recent projects and contact them. Read reviews on Google, Yelp, and the Better Business Bureau. A quality contractor will have a strong reputation.

    5. Ask About Permits and Warranty. A professional contractor will pull all necessary permits and schedule inspections. For more on permits, see what to expect during installation. Also ask about workmanship warranties and manufacturer warranties on materials.

    6. Inquire About Maintenance. After installation, your roof will need periodic maintenance. Ask if the contractor offers maintenance services. Learn more in asphalt shingle maintenance and repair.

    Red Flags: Avoid contractors who demand full payment upfront, pressure you into signing immediately, or suggest skipping permits. For insurance considerations, see does insurance cover shingle roofs. And for the materials your contractor will use, see types of asphalt shingles.
