Key Cost Factors
- Roof Size and Complexity: Larger roofs naturally require more materials and labor. Roofs with multiple peaks, valleys, chimneys, or skylights are more complex and increase labor time and material costs. A 30-square (3,000 sq ft) roof could cost between $6,000 and $6,750, based on Thumbtack data.
- Material Choice: The type of shingle or roofing material significantly impacts the price. While asphalt shingles are common and range from $3–$6 per square foot in the Atlanta area, higher-end options like standing seam metal roofs start at $300 per square ($3.00 per sq ft) for materials and labor, making a 30-square metal roof around $9,000.
- Existing Roof Condition & Tear-Off: If your current roof needs extensive repairs or a full tear-off of multiple layers, this adds to labor and disposal costs. Roofing over existing shingles can reduce upfront expenses by avoiding the most labor-intensive part of the project.
- Roof Pitch (Steepness): Steeper roofs require more safety measures, specialized equipment, and can be more difficult and time-consuming to work on, leading to higher labor costs.
- Permits and Inspections: Local building codes in Kennesaw will require permits for roof replacements, which add to the overall cost. These ensure the work meets safety and structural standards. Material costs are also expected to rise industry-wide, making it beneficial to lock in current pricing.
- Underlayment and Accessories: The quality and type of underlayment, flashing, drip edge, and ventilation components can also influence the total price of your new roof.

Tips for Hiring
- Get Multiple Quotes: Always obtain at least three detailed quotes from different local roofing contractors. This allows you to compare pricing, materials, and proposed scopes of work. A price of $7,800 is considered fair for a reroof. Be wary of discrepancies, but also of overly low estimates.
- Check Credentials: Ensure contractors are licensed, insured, and have a good reputation. Ask for proof of insurance (liability and workers' compensation) and references from previous Kennesaw clients.
- Understand the Contract: Read the contract thoroughly. It should detail the scope of work, materials to be used (brand, type, color), start and completion dates, payment schedule, warranty information for both materials and labor, and cleanup procedures.
- Inquire About Warranties: Ask about both manufacturer warranties on materials (e.g., 30-year shingles) and the contractor's warranty on labor. Architectural shingles, which typically last up to 30 years, cost between $400 and $850 per square installed. A strong warranty provides peace of mind for your investment.
Winter (December, January, February) is often considered a more affordable time to replace a roof as it's typically the slower season for roofing companies. Professionals might offer off-season discounts due to lower demand, and there's generally more scheduling flexibility.
