Homeowners planning to install new roofing for a standard 900 sq. ft. home are looking to spend about $450 to $600 per square. This translates to roughly $8,600 to $17,200 (or more).
Keep in mind that your roof serves as the topmost protective layer of your home against foreign elements. Beyond that, it also serves an aesthetic purpose.
For your reference, asphalt shingles are the most common roof in the country thanks to their cost-effectiveness and easy installation. But, tile and metal roofs are also increasing in popularity thanks to their longevity and style.

New Roofing Cost Factors
Here are a few cost factors to keep in mind as they may affect the total expenses of your new roofing project:
Labor Cost Per Square
The labor cost for a 9,000 sq ft roofing project starts from $5 to $14 per square foot. It depends on a few variables at play:
You may want to get multiple bids to determine the best deal that gives you the most bang for your buck.
Reroof a House
Reroofing a 9,000 sq ft costs between $7,500 to $25,500, covering the new roofing materials, removing the old roof, and professional installation. Costs will depend on how easy it is to remove and dispose of the existing roofing material. If your roofer discovers structural issues, this may add an extra $1,500 to $22,500 to your total tab.
How to Calculate the Roofing Cost of your 9,000 Sq. ft. Home
If you want to calculate the estimated cost of your new roof, you must first determine the roof's pitch. The pitch is the roof's incline expressed as a fraction by dividing the rise by the span. The roof span refers to the distance between the exterior of one wall's top plate to another.
On average, most roofs will have a pitch of 4/12 to 9/12 (18.4 degrees and 36.9 degrees). Several homeowners use the pitch of their roof as a primary reference in getting quotes from roofing contractors. (Related: 2022 Roofing Cost: How Much Does It Cost To Roof A 900 Sq. Ft. House?)
If you're deciding between multiple roofing quotes, here's a formula to keep in mind to determine the best value deal.
Total cost (material and labor costs) ÷ life expectancy of the roof (X years) = annual cost
Roof Repair vs. Replacement
If you believe your roof is still in good condition without any signs of damage, leak, or repair — you may want to consider its age. Roofs that have been around for more than 20 years may need a timely replacement to avoid unforeseen damages to your home's interior. Contact a local professional to assess your roof's current condition to determine if it's time for a roof replacement. (Related: Roof Replacement Cost & Consumer Guide)

Frequently Asked Questions (FAQs)
How much roofing do I need?
It will take a higher amount of roofing materials to cover an inclined area than an area that is entirely flat. The size of the uppermost floor of the house is the same as the total material you will need, plus an additional 10% more for waste. Roofs with an angle on most surfaces are a traditional type of roof, and its angled area has to be factored into the total square footage. Don't worry. Hiring a roofer can handle all the estimations to give you the exact amount of needed materials.
What is the cost of a new roof and gutters?
On average, the cost of a new gutter is nearly $1,500 for 160 feet gutters / $5.60 to $40 per foot.
What are some telling signs that I need a new roof?
Fortunately, the answer to this question is often apparent. You may need a new roof because of a hole, missing shingles, leaking issues, or infestation in the attic. Ultimately, if the roof has been around for more than 15 to 20 years, you may want to consider a timely replacement to avoid dealing with problems brought by roof damage. Other signs are curled shingles, missing/damaged flashing, and discolored ceilings or walls.
