To put on roofing shingles, you need to start with a clean roof surface, then lay down underlayment, and nail shingles row by row from bottom to top. Roofing shingles are the most popular choice for U.S. homes, and according to industry data, asphalt shingles account for nearly 80% of residential roofing projects. This guide walks you through the basic steps to install shingles properly. You will learn what tools you need, how to prepare your roof, and how to place each shingle correctly. Getting this right matters because poor installation can lead to leaks and early damage.
What Tools Do You Need?
You will need a hammer, roofing nails, a utility knife, and a tape measure. A nail gun makes the job faster than using a hammer by hand. You also need a roof ladder and safety harness because falls are the leading cause of roofing injuries.
According to the U.S. Bureau of Labor Statistics, roofing remains one of the most dangerous jobs, with a fatality rate of about 29.9 deaths per 1,000 workers in construction. Always wear safety gear before you start work.

How Do You Prepare the Roof Surface?
First, remove old shingles and debris from your roof. The surface must be flat and clean.
Next, lay down underlayment, which is a thin layer that protects the roof deck from water. This acts as a second barrier under your shingles. Nail the underlayment down every 12 to 16 inches. Then add roof flashing around chimneys, vents, and edges to stop water from seeping in.
How Do You Install the Shingles?
Start at the bottom of the roof and work your way up. The first row of shingles should hang over the edge by about one half inch. Use four nails per shingle, placed above the tar strip. Make sure each nail goes straight in and does not bend.
On the next row, offset the shingles so seams do not line up. This creates a stronger pattern. According to RubyHome, asphalt shingles cost between $4.25 and $4.95 per square foot for basic types, and architectural shingles run $4.50 to $8.25 per square foot. Proper installation is key to making your shingles last.
What About Timing and Lifespan?
Install shingles on a warm, dry day. Cold weather makes shingles brittle and hard to work with. According to industry data, asphalt shingles typically last 20 to 30 years when installed correctly. Metal roofing lasts much longer, from 40 to 80 years.
After installation, inspect your work. Look for gaps, loose nails, or bent shingles. Fix any problems right away to prevent leaks. Regular maintenance helps your roof reach its full lifespan.
| Shingle Type | Cost Per Sq. Ft. | Lifespan |
|---|---|---|
| Basic Asphalt | $4.25 – $4.95 | 20 years |
| Architectural Asphalt | $4.50 – $8.25 | 30 years |
| Metal Roofing | $10.00 – $17.05 | 40 – 80 years |
