As a construction industry professional with years of experience in the field, I can provide you with an in-depth understanding of the costs associated with roofing projects. Roofing costs can vary significantly depending on a multitude of factors, including the type of roofing material used, the complexity of the roof's design, the labor costs in your area, and the overall size of the project.

When discussing the cost of a roof, it is common to use the term "square" as a unit of measurement. A square, in this context, is equivalent to 100 square feet, and it is a standard way to estimate the size of a roof. The cost per square can vary widely based on the factors mentioned earlier.

Type of Roofing Material: The material chosen for the roof plays a significant role in determining the cost. Asphalt shingles, which are the most common type, are generally the most affordable option. However, other materials such as metal, tile, or slate can be more expensive. For instance, the cost for asphalt shingles might range from $350 to $550 per square, while metal roofing can cost between $550 and $1,200 per square.

Complexity of the Roof: Roofs with complex designs, such as those with multiple angles, valleys, or dormers, tend to be more expensive to install. The additional complexity can increase labor costs and the amount of material needed, which in turn drives up the overall cost.

Labor Costs: Labor is a significant component of the total cost for a roofing project. The cost of labor can vary by region, with some areas having higher labor rates than others. On average, labor costs can range from $150 to $450 per square, depending on the project's complexity and the local market.

Size of the Project: Larger roofs will generally cost more, both in terms of materials and labor. However, the cost per square may decrease slightly with larger projects due to economies of scale.

Warranty and Quality: The quality of the installation and the warranty offered can also affect the cost. A longer warranty or a guarantee of higher quality workmanship will typically come with a higher price tag.

Additional Factors: There are other factors that can influence the cost, such as the need for roof repairs prior to installation, the removal and disposal of the old roof, and any additional features like ventilation or insulation.

To give a more precise estimate, it's important to consider the specific details of the project at hand. However, using the average cost of $450 per square as a baseline, a ranch-style house with an average roof size of 15 to 20 squares would indeed cost between $6,725 and $9,000 for a basic composition shingles roof installed, including a typical 5-year labor warranty.

It's crucial to get multiple quotes from different roofing contractors to ensure you're getting a fair price and to compare the quality of work and the warranties offered. Remember, the cheapest option isn't always the best in terms of long-term value and durability.
