The most expensive part of replacing a roof is usually the materials. Shingles, wood, metal, or tiles cost the most money. Labor comes in second place.

According to HomeAdvisor, materials make up about 40 to 60 percent of your total roof replacement cost. This is why picking the right material matters so much.

The exact price depends on what kind of roof you need and how big your house is.

Roof Material Costs Are the Biggest Expense

When you replace a roof, materials take the biggest bite of your budget. Shingles alone can cost hundreds or thousands of dollars.

The National Roofing Contractors Association reports that asphalt shingles cost between $1.50 to $5.00 per square foot. Metal roofing runs higher, at $7 to $12 per square foot.

Wood shakes and slate are even pricier. They can cost $10 to $20 per square foot or more.

Labor Is Your Second Biggest Cost

After materials, you pay for the work. Roofers charge money to remove old shingles, fix the deck, and put on new ones.

According to industry data, labor costs make up 30 to 40 percent of your total roof job. Your roofer needs proper tools and training.

A small roof takes less time than a big one. A steep roof costs more to work on than a flat roof.

Deck Repair Can Add Big Money to Your Bill

Hidden damage under your shingles costs extra. Once roofers pull off old shingles, they see wood rot or water damage.

Replacing rotten wood boards can add thousands of dollars to your bill. Insurance industry data indicates that 30 percent of roof jobs need some deck repair.

This is why getting a roof inspection matters. You want to know about problems before work starts.

Roof Size and Pitch Change Your Total Price

Bigger roofs cost more. A 3,000 square foot roof costs more than a 1,500 square foot roof.

A steep pitch roof takes longer to work on. Roofers move slower on steep angles for safety.

Roof TypeCost Per Square FootTotal for 2,000 Sq Ft
Asphalt Shingles$3.00 to $5.00$6,000 to $10,000
Metal Roofing$7.00 to $12.00$14,000 to $24,000
Wood Shakes$10.00 to $15.00$20,000 to $30,000
Slate Tiles$15.00 to $20.00$30,000 to $40,000

Removal and Disposal Cost Money Too

Taking off old shingles and throwing them away costs money. Roofers must haul away the old material safely.

According to Angi, tear-off and disposal costs between $1 and $2 per square foot. For a 2,000 square foot roof, that is $2,000 to $4,000.

Some jobs need new plywood underneath. This adds to your costs as well.

Roof Underlayment and Other Hidden Costs

Under your shingles is a layer called underlayment. This protects your house from water leaks. New underlayment must be added during replacement.

You might also need new flashing around chimneys and vents. New gutters can cost extra too. Here are common add-on costs:

  • Underlayment: $0.75 to $1.50 per square foot
  • Flashing repair: $300 to $1,000
  • New gutters: $4 to $9 per linear foot
  • Ventilation fans: $300 to $900 each
  • Chimney repair: $500 to $2,500

Location and Season Matter for Price

Where you live changes your roof replacement cost. Big cities cost more than small towns. Northern states with snow add to the price too.

Recent studies show that roof replacement costs vary by 20 to 40 percent depending on region. Winter jobs sometimes cost more because weather slows work down.

Summer is busy season for roofers. This can make prices higher in warm months.

What Can You Do to Save Money

Picking asphalt shingles saves money compared to metal or slate. Getting quotes from three roofers helps you find the best price.

Ask about payment plans or discounts. Some roofers offer deals for cash payment.

Doing roof work in fall or spring sometimes costs less. You can also ask your insurance company about coverage for damage.

  • Get three price quotes before choosing
  • Pick a standard shingle color to save money
  • Schedule work during slower seasons
  • Ask about warranties and guarantees
