Tools & Materials You’ll Need

• Asphalt shingles

Step-by-Step Roofing Installation Guide for Asphalt Shingles

1. Remove the Old Roofing

If you’re replacing an old roof, the first step is to strip away existing materials. Use a pry bar and roofing shovel to remove shingles, nails, and underlayment. Inspect the roof deck for any signs of rot or water damage.

2. Inspect and Prepare the Decking

Check the plywood or OSB sheathing underneath. Replace any damaged or weak sections. A solid, flat surface ensures a smooth installation.

3. Install the Drip Edge

Start at the eaves and install metal drip edge flashing. This prevents water from curling under the roofing and causing damage.

4. Roll Out the Underlayment

Lay down roofing underlayment to create a moisture barrier. Overlap each row by at least 2 inches and staple or nail it securely. Underlayment adds extra protection beneath the shingles.

5. Apply Starter Strip Shingles

Begin at the lower edge of the roof. Starter strips provide a solid base and prevent wind uplift on the first course of shingles.

6. Install Asphalt Shingles

Start with the first row directly above the starter strip. Use a chalk line to ensure straight alignment. Nail shingles about 6 inches up from the bottom and 1 inch from each edge. Overlap each successive row by half a tab.

7. Flashing and Ventilation

Install metal flashing around chimneys, skylights, and vents to prevent water intrusion. Ensure that attic vents are not obstructed to allow proper airflow.

8. Cap the Ridge

Use ridge cap shingles to finish the peak of the roof. Nail them in place and seal exposed nails with roofing cement.

9. Final Inspection and Cleanup

Walk the roof to check for missed nails or unsecured shingles. Clean debris, check for alignment, and ensure flashing is properly installed.

Tips for DIY Roofing Installation

• Safety First: Always wear proper footwear, use harnesses, and work with a partner.
• Weather Watch: Install on clear, dry days for best results.
• Use Quality Materials: Cheap shingles may save money upfront but can fail faster.
• Take Your Time: Rushing can lead to mistakes and leaks down the line.

If you’re unsure about any part of the process, it's wise to consult with professionals. Mistakes in roofing installation can lead to expensive repairs later on.

Maintenance After Installation

To maximize the life of your asphalt shingle roof:

• Inspect it twice a year
• Clean gutters and downspouts regularly
• Remove moss or algae buildup
• Replace damaged shingles promptly
• Schedule professional inspections every few years

Whether you're a DIY enthusiast or plan to hire a contractor, understanding the process helps you make informed decisions and avoid common pitfalls.
