To do shingle roofing, you need to prepare your roof deck, lay down underlayment, and nail shingles in overlapping rows from bottom to top. This is hard work that takes skill and safety gear. According to RubyHome, roof installation costs range from $4 to $40 per square foot, which means a 1,700 square foot roof can cost $6,800 to $68,000. Most homeowners hire pros, but some try DIY and can save about 50% on labor costs, though mistakes lead to bigger problems later.

Step 1: Get Your Materials Ready

You will need asphalt shingles, roofing nails, underlayment, flashing, and a nail gun. According to RubyHome, basic asphalt shingles cost $4.25 to $4.95 per square foot, while architectural shingles run $4.50 to $8.25 per square foot. Asphalt shingles are the most popular choice because nearly 80% of roofing projects use them.

Wear a harness, gloves, and boots with good grip. Safety is not optional.

Step 2: Install Underlayment and Flashing

Underlayment goes under the shingles to catch water leaks. It acts like a second skin for your roof. Flashing seals the edges around chimneys, vents, and walls.

Nail the underlayment with a hammer tacker. Make sure it overlaps by 2 inches on each row. This keeps water from sneaking underneath.

Step 3: Lay Shingles from Bottom to Top

Start at the bottom edge of your roof. Use roofing nails, not regular nails. Each shingle needs 4 to 6 nails.

The second row overlaps the first by about 5 inches. This creates a water-blocking system. According to industry data, asphalt shingles last 20 to 30 years if installed correctly. Keep rows straight and nail placement consistent.

Common Mistakes to Avoid

Do not nail too high or too low on shingles. Do not leave gaps between shingles. Do not skip the underlayment. According to This Old House, 79% of homeowners who did roof work hired contractors instead of doing it themselves. That makes sense because one mistake costs thousands in repairs.

Shingle roofing takes time, care, and the right tools. If you are unsure, hire a pro. According to RubyHome, the average roof replacement costs $9,526, but DIY mistakes can make that bill much bigger.
