Preparing the Roof Deck: Inspection and Repairs
Before installing new shingles, it’s essential to inspect the roof deck for any signs of damage, rot, or warping. Remove all old roofing materials, including nails and underlayment, to expose the bare wood. Replace any compromised decking to ensure a solid foundation for your new roof.
Once the deck is clean and dry, install drip edge flashing along the eaves and rakes. This metal strip helps direct water away from the fascia and prevents wind-driven rain from getting under the shingles. Proper preparation at this stage is key to a long-lasting, leak-free roof.
Installing Underlayment and Starter Strips
With the deck prepared, the next step in this asphalt roofing installation guide is to roll out the underlayment. Begin at the eaves and work your way up the slope, overlapping each row by at least two inches. Secure the underlayment with cap nails or staples, ensuring it lies flat without wrinkles or gaps.
Starter strip shingles are installed along the eaves to provide extra protection against wind and water infiltration. These strips also help the first course of shingles adhere properly and create a straight edge for the rest of the installation.

Laying Asphalt Shingles: Step-by-Step Process
Proper shingle placement and nailing are critical for a watertight and wind-resistant roof. Here’s a breakdown of the main steps:
- Snap horizontal chalk lines to keep rows straight and evenly spaced.
- Begin with the first course of shingles at the lower edge, overlapping the starter strip.
- Stagger shingle joints in each row to prevent water infiltration.
- Use the correct number of nails per shingle (typically four, or six in high-wind areas), placed just below the adhesive strip.
- Continue up the roof, maintaining consistent overlap and alignment.
- Install ridge cap shingles along hips and ridges for a finished look and added protection.

Expert Tips for a Durable and Attractive Roof
To ensure your new roof performs well for decades, consider these professional recommendations:
- Ventilation: Proper attic ventilation prevents heat and moisture buildup, which can damage shingles and reduce their lifespan.
- Flashing: Pay special attention to valleys, chimneys, and skylights. Use high-quality flashing and sealant to prevent leaks in these vulnerable areas.
- Weather Considerations: Install shingles in mild, dry weather. Extreme temperatures can affect shingle flexibility and adhesion.
- Quality Materials: Invest in reputable brands and products. For more on what makes up a shingle roof, see what is asphalt shingle roofing.
- Regular Maintenance: Inspect your roof annually and after severe storms. Promptly address any damaged or missing shingles.
Following these guidelines will help you avoid common mistakes and maximize the value of your investment.
