The cost can be more for larger homes, homes with complex roof designs, or when installing more expensive materials.

Roof Replacement or Repair?
When leaks occur the first question to ask is whether the roof can be repaired or if it should be replaced. If the roof is relatively new and the leaks are simple to repair then a repair may be in order.
If it’s over 20 years old and the leaks are widespread then a full replacement may be necessary. Most will be somewhere in between however and the decision may require an expert. Consult a roofer to get an inspection and identify your options.

Types of Roofing Materials
There are many types of roofing materials, and the choice of material can be a major factor in curb appeal and the appearance of your home. The right material for you depends on your personal taste, preferences, and budget.
The most common and cost effective roofing material is the 3-tab asphalt shingle. These shingles often cost $150-$200 per square. A basic 3-tab shingle is considered a 25-year roof.
Architectural shingles are a different style of asphalt shingle that are thicker than a 3-tab shingle and layered for an upscale look. These shingles often cost $200-$400 per square. Architectural shingles are available in 30 or 50 year varieties.
Cedar or Wood Shake
Wood shingles such as cedar shake have a distinct look and change color to a beautiful gray over time. Cedar shake often cost $300-$500 per square and last 30 years. Though beautiful, wood shingles are more vulnerable to fire and may need to be treated to prevent mold and insect damage.
Metal roofs such as steel panels offer a long service life and are extremely durable. Steel can also be painted to match the style of the home. Steel panels cost $300-$800 per square. Copper panels are also a great option but are more expensive and can cost up to $1,500 per square.
Tile roofs are available in several shapes, styles, and colors, and they can add a lot of character to your home. Tile is usually made of concrete, clay, or other ceramic materials and usually costs $500-$800 per square. Tile roofing is very durable and can last a long time if installed well.
Slate stone roofing is the longest lasting material available and can last over 100 years with a proper installation. Slate is also an extremely elegant option. Slate is one of the most expensive options and can cost $600-$1,500 per square or more. Slate is also very difficult to install and you should find an experienced roofing contractor for this installation.
Roof Installation Labor Costs
Installing a new roof is a time intensive project and labor costs account for a significant amount of the total installation price. Most roofers will charge somewhere around $300 per square for labor.
This can vary based on geographic location and labor rates in your area. On average labor makes up 40%-50% of the installation price, but factors such as the complexity or pitch of the roof will require additional time and labor to accommodate.
Roof Installation Cost Factors
There are many things that make up the price to install a new roof in addition to the material choice and labor costs. Additional materials such as underlayment, venting, flashing, trash removal, and permits are often required for an installation and add to the cost. There are some other factors that may affect the price of installation to be aware of.
Steep roof pitch: A steep roof pitch can add to the cost of installation as it will be more time-consuming to work on a steeper pitch. Depending on the pitch additional equipment may also be necessary.
Complex roof architecture: A complex roof architecture is more time-consuming to complete than a simple flat roof due to angles and fitting. Complex roof structures also require additional flashing, adding to the total cost.
Tear-off of old roof: If you need to have an existing roof removed prior to installation expect to pay an additional $100-$150 per square to have the existing shingles removed. This may be a necessary step depending on how many layers of existing roof there are.
Roof deck repair: If the existing roof deck is rotten or damaged it might need to be repaired or completely replaced which could add to the expense of the installation.
Skylights and chimneys: Skylights and chimneys require a bit of time to add flashing and prevent the area from leaking. This can add labor and material costs to the installation.
