Roofing calculator cost

Roof size and square footage

Larger roofs require more materials and labor, thereby increasing the overall expense. A good starting point is to calculate your roof area. Roofing contractors usually measure roofs in "squares", where one square equals 100 square feet. For example, if your roof is 2,000 square feet, that's 20 squares. From there, you can start estimating costs based on the materials and labor involved.

Roof pitch and complexity of work

The steepness, or pitch, of your roof affects both material requirements and labor intensity. Steeper roofs are more challenging to work on, leading to higher labor costs. Additionally, complex designs with multiple angles or features, such as dormers, can further increase expenses.

Choice of roofing materials

The type of material you select significantly impacts the total cost and longevity of your roof:

• Asphalt shingles: These are affordable and popular, with an average lifespan of 20 to 25 years. Average cost: $3.50 to $7.00 per square foot
• Architectural shingles: These are a premium variety of asphalt shingles and offer enhanced durability and aesthetic appeal. They last 30 to 50 years. Average cost: $4.50 to $9.00 per square foot
• Metal roofing: Durable and long-lasting, metal roofs can endure for 40 to 75 years but come with higher upfront costs. Average cost: $7.00 to $15.00 per square foot
• Wood shakes: These provide a natural look with a lifespan of 25 to 30 years. But they require regular maintenance and are less fire-resistant. Average cost: $6.00 to $12.00 per square foot
• Tile roofing: Includes clay or concrete tiles; it is known for durability and longevity. It often lasts 40 to 50 years. However, such a roof is heavy and may require additional structural support. Average cost: $10.00 to $20.00 per square foot
• Slate roofing: This is a high-end natural stone material option with a lifespan exceeding 100 years. This type of roof offers exceptional durability. Average cost: $15.00 to $30.00 per square foot

Labor costs

Labor typically makes up about 60% of the total cost of a roof replacement. It's a good idea to get quotes from multiple roofing contractors in your area. On average, labor costs range from $1.50 to $3.00 per square foot. For a typical 2,000-square-foot roof (20 squares), this translates to $3,000 to $6,000 in labor alone. The cost may vary depending on the difficulty of the work and the different roof types. For example, an asphalt shingle roof installation is easier, while a slate or clay tile roof and metal roofing may require a certain level of expertise and cost more in terms of labor. Their roof repair will also cost more.

Removal of existing roof

If the existing roof needs to be removed before installing a new one, expect additional labor and disposal costs. The complexity and number of layers in the existing roof can influence these expenses. On average, the cost to remove an existing roof ranges from $1 to $5 per square foot. For a 2,000-square-foot roof, you can expect to pay $2,000 to $10,000 for tear-off and roof disposal.

Permits and roof inspections

Permits are required for most roof replacements to ensure the work meets local building codes. Roofing permits typically cost $100 to $500, depending on your city or county. Inspections usually cost $100 to $300. Keep in mind that inspections may be required before, during, and after the project to verify compliance with safety and building standards.

Roofing warranties

Investing in a comprehensive warranty can provide peace of mind but may increase the initial cost. Contractor warranties can range in price depending on coverage and duration.

How to hire a roofer?

If you're looking for a roof replacement pro, make sure you find a reliable, licensed, and insured one. Always check your potential roofer's references. Call all of them or at least two of the references to get a good idea of the roofer's work process and the final output. Lastly, make sure the roofer does a thorough roof inspection and answers all your questions.

Pro tip: Before getting roof replacement/repair cost quotes (at least three), do your due diligence on the roof installation prices in your area. It will help you negotiate a good deal with the roofer.

What is the best way to pay for a roof replacement?

There are several ways to finance a roofing project. You can opt for a home equity loan or a home equity line of credit, aka HELOC. Or apply for a personal loan if you're specifically looking for an unsecured loan. Other funding options include cash-out refinancing or a government-aided loan.

An easy way to compute your loan payments for a specific loan amount is to use a reliable loan calculator. It will tell you how much you can expect to pay every month and for what period. Plus, you can compare all your financial options at once.

How much does a new roof last?

An average roof lasts about 30 years. Of course, it will depend on the roof type and its maintenance.

How long does a complete roof replacement take?

In most cases, a roof on a standard-sized home can be replaced in a day or two. However, it could take three to five days or up to three weeks, depending on the weather, complexity of the work, and accessibility to your home. A roof repair work would be much quicker.
