To do roofing step by step, you need to prepare the area, remove old shingles, check the roof deck, add underlayment, install new shingles, and finish the edges. Roofing is hard work and takes time. According to RubyHome, the average roof replacement cost is $9,526, and installation runs $4 to $40 per square foot. Most roofs last 20 to 50 years depending on the material. Hiring a pro is often safer than doing it yourself, but if you want to learn, follow these steps.

Step 1: Remove the Old Roof

Start by taking off all old shingles and nails. Use a pry bar to lift shingles and a hammer to pull nails out. Work from the top down toward the gutters. According to RubyHome, DIY can save about 50%, but mistakes cost more money later.

Wear gloves and safety gear. Old nails are sharp and can hurt you.

Step 2: Check the Roof Deck

Once shingles are gone, look at the wood underneath. Press on soft spots with a screwdriver. If wood is rotted, it must be fixed before new shingles go on.

Make sure the deck is flat and clean. Sweep away dirt and old nails.

Step 3: Add Underlayment and Start Shingles

Roll out underlayment paper across the roof. Staple it down. This protects the wood from water. Then start at the bottom and nail down the first row of shingles. Each row overlaps the one below. According to RubyHome, basic asphalt shingles cost $4.25 to $4.95 per square foot. Architectural shingles cost $4.50 to $8.25 per square foot.

Use the right nails. Four nails per shingle is standard.

Step 4: Finish and Check Everything

Keep adding rows until you reach the top. Seal edges with roofing cement. Check that all nails are tight and shingles are flat.
