Getting a roof replacement is an expensive ordeal. Homeowners want to know what’s included in the cost so they can make the best decision when looking at the whole picture of replacing their roof. In this article, we will cover what goes into the cost of a roof replacement, including materials, labor, additional services, and more.

What Goes Into the Cost of a Roof Replacement?


The primary factor that goes into the cost of a roof replacement is the materials used. Asphalt shingles make up the majority of roofs on homes and are the most affordable option, ranging from $5-$15 per square foot. Metal roofs are more long-lasting, environmentally friendly, and require less maintenance, but come with a slightly higher cost, from $10-$25 per square foot. High-end tile, slate, or wood shingle roofs can range from $7-$50 per square foot.


When factoring in labor costs of a roof replacement, most contractors charge anywhere from $50-$70 per hour, depending on the type of job and location. This can include labor for removing and disposing the old roof, any associated repair work such as flashing, drip edging, and installing the new roof. Removing and disposing of the old shingles is one of the biggest labor costs associated with a roof replacement.

Additional or Special Services

Specialized services such as chimney cap installation, new skylight installation, or any additional ventilation or insulation can add an extra cost to your roof replacement. Other issues such as rotten or soft wood, or a wet-roof deck could add an additional cost.


Inspections of the old roof and new roof are included in the cost of your roof replacement. The inspector will check the roof before the work starts, and after the installation has been completed to make sure the job was done correctly. An inspection usually costs around $200.


Depending on where you live, you may need to get a permit before you can start replacing your roof. A permit should include any additional costs and is usually necessary when the roofing job requires structural changes, is higher than a specified ground level, or requires any special tools to replace. The cost of permits can range anywhere from $50-$400.

Vents, Valleys, and Drip Edging

Vents, Valleys, and Drip Edging need to be considered when budgeting for a roof replacement. Vents can cost up to $30 each, and drip edging can cost $0.50 per linear foot. Valleys, the corner where two roof planes meet, range from $100-$500 depending on the material and type of installation.


The cost of a roof replacement also includes the cost of the warranty, which covers any repair expenses for a longer period of time. Depending on the type of shingles you choose, warranties can range anywhere from 20 years to a lifetime warranty.
