Asphalt shingles come in a variety of forms, including:

  • Three-Tab Shingles: The most basic and economical option, featuring a flat, uniform appearance.
  • Architectural Shingles (also known as dimensional or laminate shingles): These offer a more textured, layered look and provide better durability.
  • Luxury Shingles: These imitate the appearance of more expensive roofing materials like slate or wood shakes, offering premium aesthetics and performance.

Preparation for Installation

When it’s time to install roof shingles, a little preparation goes a long way.

Assessing Your Roof

Before you start, inspect your roof for any damage or structural issues that need addressing. Look for:

  • Rotten or damaged deck boards
  • Loose or missing flashing
  • Signs of water damage or leaks

Gathering Materials and Tools

Ensure you have the following materials and tools:

  • Asphalt shingles
  • Roofing nails
  • Underlayment
  • Drip edge
  • Flashing
  • Roofing cement
  • Chalk line
  • Hammer or pneumatic nail gun
  • Utility knife
  • Ladder
  • Safety harness

Removing Old Shingles

If you’re replacing an existing roof, you’ll need to remove the old shingles. Use a roofing shovel or pitchfork to lift and dispose of the old materials. Be cautious to avoid damaging the roof deck during this process.

A Simple 8 Step Installation Guide

Whether you’re looking to install asphalt shingles on your own, or are interested in hiring a professional, it’s important to know what to expect. Here are the key steps when it comes to installing shingles.

Step 1: Install the Drip Edge

Start by installing a metal drip edge along the eaves and rakes of your roof. The drip edge prevents water from seeping into the roof deck and directs it away from the fascia board.

  • Use roofing nails to secure the drip edge, spacing them about 12 inches apart.
  • Overlap sections of the drip edge by at least 2 inches to ensure continuous protection.

Step 2: Lay the Underlayment

The underlayment acts as a secondary barrier against water infiltration.

  • Roll out the underlayment horizontally across the roof deck, starting from the eave and working your way upward.
  • Overlap each row by at least 4 inches.
  • Secure the underlayment with roofing nails or staples, ensuring it’s taut and wrinkle-free.

Step 3: Install Flashing

Flashing is essential for waterproofing areas where the roof meets vertical surfaces, such as chimneys, skylights, and vents.

  • Cut pieces of flashing to fit around the protrusions.
  • Secure the flashing with roofing nails and seal the edges with roofing cement for added protection.

Step 4: Apply Starter Shingles

Starter shingles provide an extra layer of protection along the eaves and rakes.

  • Cut off the tabs from a row of three-tab shingles to create starter shingles.
  • Lay the starter shingles along the eaves, ensuring they overhang the drip edge by about 1/4 to 3/4 inch.
  • Secure the starter shingles with roofing nails, placing them about 6 inches apart.

Step 5: Install the First Row of Shingles

Now comes the main part of the installation—the asphalt shingles themselves.

  • Begin at the bottom corner of the roof and work your way across the eaves.
  • Lay the first row of shingles, ensuring they overhang the starter shingles slightly.
  • Use the chalk line to ensure the shingles are aligned properly.
  • Secure each shingle with four roofing nails, placing them just below the adhesive strip and about 1 inch from each edge.

Step 6: Continue Installing Rows of Shingles

  • Lay the second row of shingles, staggering the seams to prevent water infiltration.
  • Use the cut-off pieces from the previous row to start the next row.
  • Continue this process, working your way up the roof. Ensure each row is aligned properly using the chalk line.

Step 7: Install Ridge Cap Shingles

Ridge cap shingles protect the roof’s peak and add a finishing touch.

  • Cut three-tab shingles into individual caps.
  • Bend each cap to fit over the ridge and secure it with roofing nails.
  • Overlap each cap slightly, working your way across the ridge.

Step 8: Final Inspection and Cleanup

  • Inspect the roof for any missed nails or shingles that need securing.
  • Clean up any debris from the installation process, ensuring your gutters are clear of materials.

Maintenance Tips for Asphalt Shingle Roofs

After installing your new shingles, you’ll want to ensure that they stay in top-notch shape! Here are the ultimate maintenance tips to keep your roof healthy.

⏰ Regular Inspections

Conduct regular inspections, especially after severe weather, to check for:

  • Loose or missing shingles
  • Damaged flashing
  • Debris buildup

🌱 Moss and Algae Prevention

Clean your roof periodically to prevent moss and algae growth. Use a mixture of water and bleach, applying it gently with a soft-bristle brush.
