Cost of a New Roof

How Much Does a New Roof Cost?

The cost to replace a roof will vary, with a typical range between $5,000 and $12,000 but can be as high as $30,000. A new asphalt roof is usually between $3.50 and $5.00 per square foot while a new metal roof will cost between $8.00 to $10.00 per square foot. An average roof is approximately 1,700 square feet. The cost depends on several factors, including square footage, material, difficulty, damage to the roof, and more.

Cost to Replace Architectural Asphalt Shingles

A common type of asphalt shingle is the 30- or 50-year architectural shingle or laminate shingle. These types of shingles are more durable and higher quality because they are thicker than traditional three-tab shingles.

Installation cost for 30-year architectural shingles is typically $3.50 to $5.00 per square foot. 50-year architectural shingles, considered a premium product, are even stronger, with costs ranging from $4.50 to $7.00 per square foot.

Most Owens Corning laminated shingles are rated for 110 to 130 mph winds. Owens Corning shingles also include SureNail Technology, which provides extra grip in the nailing area. WeatherGuard technology provides maximum impact resistance to protect against storms.

In addition to shingles, other factors contribute to the overall price of a roof. So what else goes into the cost of a roof replacement?

Nails

As simple as it might seem, replacing a roof requires a lot of nails. In the last couple of years the cost of a box of nails increased from $17 to $30, and an average sized roof needs two boxes of nails.

Underlayment

A durable synthetic underlayment on a roof as extra protection against water damage is often recommended by roofing specialists. In case of damage to the shingles, underlayment will protect the home from leaks and mold, and other issues caused by water.

Ice and Water Barrier

A quality ice and water barrier, also called an ice and water shield (IWS), will work with most roofs. Some IWSs are designed to flex and adhere to the roof. The IWS provides extra protection to prevent water from seeping underneath the shingles from storms, snow, and freeze/thaw cycles.

Starter Shingles

Starter shingles are another necessary part of the roofing process to protect a roof from water. These shingles are installed before the first course of the finished shingles. They direct water off the roof instead of letting it sit and seep into a home. Most manufacturers require starter shingles as part of their warranty.

Ventilation

Like all areas of a home, proper ventilation and airflow contribute to a roof’s longevity. Without necessary ventilation, hot air cannot leave the attic, resulting in mold and rotting materials issues. Ventilation also helps with energy efficiency in a home.

Roof Flashing

Roof flashing protects roofs from water. It seals any opening in a roof, like where a chimney or skylight goes through the roof. Flashing prevents water from leaking in through these vulnerabilities, which further prevents water damage and mold. Flashing is an essential component in roof installation and replacement.

Drip Edge

The drip edge is a formed strip of metal installed at a roof’s edge beneath the starter shingles. It extends beyond the fascia and directs water to the gutter system. By redirecting the water flow, the drip edge prevents water from sneaking under the shingles and causing rot and limiting entry points for pests.

Roof Replacement Labor

Although the materials are a large part of the cost of the roof, labor is also a factor in the overall cost and can account for up to 60% of the cost of a new roof.

Labor costs change because roofers go where they are needed most. When storms march through an area, bringing damaging winds, hail, and tornadoes, roofers are in high demand. Homeowners in an unaffected area may have a more difficult time finding a company for the roof.

Is Replacing the Roof a Good Investment?

Although the upfront cost is steep, replacing the roof is a significant investment. Depending on the factors, a new roof can increase a home’s value $10,000 to $20,000.
