To install roofing, you need to prepare your roof surface, add underlayment, and then install shingles or metal panels from bottom to top. The process takes time and skill, so many homeowners hire professionals instead of doing it themselves. According to RubyHome (2025), roof installation costs range from $4 to $40 per square foot, depending on your material choice. Doing it yourself can save about 50%, but mistakes can cost you more money later. This guide explains the basic steps for roof installation.

What Materials Do You Need?

First, pick your roofing material. According to RubyHome (2025), asphalt shingles are the cheapest option at $4.25 to $4.95 per square foot. Metal roofing costs more but lasts longer, ranging from $5.50 to $17.05 per square foot depending on the type.

You will also need underlayment, flashing, nails, and sealant. Underlayment goes under your shingles to stop water leaks.

How Do You Prepare the Roof?

Start by removing old shingles and debris. Make sure the roof deck is smooth and dry.

Next, install underlayment across the entire roof. This acts as a waterproof barrier. Then add flashing around chimneys, vents, and edges. Flashing prevents water from getting into your home.

What Are the Basic Installation Steps?

Start at the bottom of your roof and work your way up. According to RubyHome (2025), the average roof size in the U.S. is 1,700 square feet. Begin by nailing down your first row of shingles or panels.

For shingles, overlap each row. Use the right number of nails per shingle, usually 4 to 6. Keep rows straight and even. Continue upward until you reach the top.

For metal panels, snap them together or bolt them down. Make sure panels are tight and secure.

Why Should You Hire a Professional?

Roofing is dangerous. According to RoofLink (2025), roofing remains one of the most hazardous jobs in America. According to the U.S. Bureau of Labor Statistics, roofers earn an average of $26.85 per hour, reflecting the skill and risk involved.

Professionals know how to work safely at height. They understand building codes and warranty requirements. A bad installation can cause leaks and cost you thousands to fix. According to RubyHome (2025), asphalt shingles typically last 20 to 30 years with proper installation. Poor work shortens that lifespan.

Material Type	Cost per Sq. Ft.	Lifespan
Asphalt Shingles	$4.25, $4.95	20, 30 years
Metal Roofing	$5.50, $17.05	40, 80 years
Cedar Shingles	$8.00, $14.30	30+ years
