A Dallas homeowner needs to replace a 15-year-old 3-ton central AC unit and gas furnace. Getting quotes for a Carrier 16 SEER2 system installed.
Takeaway: HVAC costs in Dallas run ~10% below the national median due to high installer density. Same system in San Francisco installs for $11,000-$15,000. Efficiency upgrades (18 SEER2 vs 16) typically add $1,200-$1,800 but recover cost in 5-8 years in high-AC-usage climates.
Published cost guide ranges represent the middle 80% of contractor bids nationally. Your quote depends on local labor market, permit requirements, project complexity, and seasonal demand. High-demand periods (spring/summer for exterior work) push quotes 10-20% above off-season pricing.
On major projects ($5,000+), quote variance between contractors often spans 40-60%. The lowest bid is not necessarily the best value — verify licensing, insurance, and references. Extremely low bids often indicate scope gaps or willingness to upsell change orders during the project.
Cost guide data is updated quarterly at best. Lumber, copper, and appliance prices are volatile. During supply chain disruptions (2020-2022), material costs moved 30-100% within months. For projects starting more than 60 days out, ask contractors to lock in material pricing or add an escalation clause.
Permit fees range from $50 (minor work) to $3,500+ (major structural projects) and vary by municipality. Some contractors include them in proposals; others bill separately. For large projects, ask explicitly whether the quote includes permit fees and who is responsible for pulling them.

A roof replacement is one of the largest home improvement expenses you may face. The national average in 2025 ranges from $8,500 to $14,500 for a standard asphalt shingle roof on a typical 1,700 square foot home. However, costs vary dramatically based on four primary factors: material choice, roof size, geographic region, and the complexity of the job including the number of stories, roof pitch, and whether tear-off of the old roof is needed.
According to data from HomeAdvisor and Angi, the median homeowner spends about $10,000-$12,000 on a complete roof replacement. Premium materials like metal, tile, or slate push costs significantly higher. Understanding these cost drivers helps you budget accurately and avoid surprise expenses.
Material selection is the single biggest factor in roof replacement cost. Here is what each major roofing material costs per square foot installed in 2025, including both materials and labor:
Asphalt shingles remain the most popular residential roofing material in the United States, used on roughly 80% of homes. Three-tab shingles cost $4.50-$6.00 per square foot installed. Architectural (dimensional) shingles, which are thicker and more durable, cost $5.50-$8.50 per square foot. Asphalt shingles last 20-30 years and come in the widest range of colors and styles. For a 1,700 sq ft roof, expect to pay $7,650-$14,450.
Metal roofing has surged in popularity due to its 40-70 year lifespan and energy efficiency. Standing seam metal roofs cost $9-$14 per square foot, while metal shingles or tiles run $10-$17 per square foot. A metal roof on a 1,700 sq ft home costs $15,300-$28,900. Metal reflects solar heat, potentially reducing cooling costs by 10-25%.
Clay and concrete tile is common in the Southwest and Southeast. Installation costs $12-$25 per square foot, putting a 1,700 sq ft roof at $20,400-$42,500. Tile roofs last 50-100 years but weigh 2-4 times more than asphalt, sometimes requiring structural reinforcement that adds $2,000-$10,000.
Natural slate is the premium option at $18-$45 per square foot installed. A 1,700 sq ft slate roof costs $30,600-$76,500. Slate lasts 75-150+ years and is virtually fireproof. Installation requires specialized labor, and the extreme weight may necessitate structural upgrades.
Flat roofing (TPO, EPDM, PVC) is used on low-slope and flat roofs. Costs run $4-$10 per square foot installed, or $6,800-$17,000 for a 1,700 sq ft roof. TPO and PVC are more expensive but last 20-30 years, while EPDM is cheaper but has a 15-20 year lifespan.
Roof size and complexity: Cost scales directly with square footage, but complex roofs with multiple valleys, hips, dormers, or skylights cost 10-30% more in labor due to additional cutting, flashing, and sealing work. A simple gable roof is the least expensive to replace.
Number of stories: Second-story roofs cost 15-20% more than single-story due to scaffolding, safety equipment, and the difficulty of hauling materials. Three-story homes add 20-25% to labor costs. Many contractors charge a per-story surcharge.
Tear-off vs. overlay: Removing the existing roof (tear-off) costs $1.00-$1.50 per square foot, or $1,700-$2,550 for a 1,700 sq ft roof. Overlay (installing new shingles over old) saves this cost but is only possible with one existing layer of asphalt shingles. Most building codes limit you to two total layers. Tear-off is recommended because it allows inspection of the roof deck for damage.
Roof deck repairs: Once old shingles are removed, damaged plywood or OSB sheathing must be replaced. Budget $70-$100 per sheet of plywood. On average, 5-15% of the roof deck needs replacement, adding $300-$1,500 to the project.
Permits and inspections: Most municipalities require a building permit for roof replacement, costing $200-$500. Some areas also require inspections, adding $100-$300. In certain historic districts, material and color choices may be restricted.
Where you live significantly affects roof replacement cost. Labor rates, material availability, building codes, and weather patterns all play a role.
The West Coast (California, Oregon, Washington) is the most expensive region, with costs running 15-25% above national averages due to high labor rates and strict building codes. The Northeast (New England, Mid-Atlantic) runs 10-20% above average due to higher labor costs and the need for ice and water shield underlayment in snow-prone areas. The Midwest tracks close to national averages. The Southeast tends to be 5-10% below average due to lower labor rates, though hurricane-prone coastal areas may require wind-rated materials that increase costs. The Southwest runs 0-10% above average with tile being more popular and often required by HOA rules.
Not every roof problem requires full replacement. Consider repair if the roof is under 15 years old and damage is isolated to a small area. Typical repairs cost $300-$1,500 for patching, reflashing, or replacing a few shingles. However, replacement makes more sense when your roof is over 20 years old, has widespread shingle deterioration, multiple leaks, or when repair costs exceed 30% of replacement cost. Insurance may cover storm damage but rarely covers wear and aging.
Get at least three quotes from licensed, insured contractors. Ask for itemized estimates that break out materials, labor, tear-off, and disposal separately. Consider replacing your roof in the off-season (late fall or early spring) when contractors may offer 5-15% discounts. Look into manufacturer rebates on premium materials. Check if your homeowners insurance covers storm damage. Some states offer tax credits or rebates for energy-efficient roofing like cool roofs or solar-ready metal roofs.
Most homeowners pay for roof replacement through savings, home equity loans (5-8% APR), HELOCs, or contractor financing. Some roofing companies offer 12-18 month same-as-cash financing. FHA Title I loans and Fannie Mae HomeStyle loans also cover roof replacement. For metal or solar-ready roofs, PACE financing may be available in some states. Avoid high-interest personal loans or credit cards if possible, as the interest can add 15-25% to the total project cost.
The national average roof replacement cost in 2025 is $8,500-$14,500 for a typical 1,700 sq ft roof with asphalt shingles. Metal roofs cost $15,000-$30,000, tile runs $20,000-$40,000, and slate can exceed $30,000-$75,000 depending on size and region.
Asphalt shingles cost $4.50-$8.50 per sq ft installed. Metal roofing runs $9-$17 per sq ft. Clay or concrete tile costs $12-$25 per sq ft, and natural slate ranges from $18-$45 per sq ft. Flat roofing costs $4-$10 per sq ft.
Yes. Each additional story adds 15-25% to labor costs due to increased safety equipment, scaffolding, and difficulty carrying materials. A 2-story home costs 15-20% more than a single-story, and a 3-story home costs 20-25% more.
A new asphalt shingle roof recovers about 60-68% of its cost at resale. A new metal roof can recover 50-65%. Beyond direct ROI, a new roof removes a major buyer objection and can accelerate the sale.
If your roof is over 20 years old, has widespread damage, or repair costs exceed 30% of replacement cost, full replacement is usually more cost-effective. Isolated damage on a newer roof is typically worth repairing. Missing or curling shingles, leaks in multiple areas, and sagging are signs you need replacement.
Most residential roof replacements take 1-3 days for asphalt shingles on a standard-sized home. Tile or metal roofs take 5-7 days. Complex roof designs with multiple slopes, dormers, or chimneys add additional time. Weather delays can extend the timeline.
Slate roofs last 75-100 years. Metal roofs last 40-70 years. Clay or concrete tile lasts 50-75 years. Asphalt shingles, the most common and affordable option, last 20-30 years. Higher upfront cost for durable materials is offset by fewer replacements.
Insurance covers roof damage from covered perils like storms, hail, fire, and falling objects. It does not cover wear and tear, age-related deterioration, or lack of maintenance. Filing a claim requires damage from a specific covered event documented with photos.
Signs include curling, cracking, or missing shingles, granules in gutters, daylight visible through roof boards, sagging areas, and a roof age exceeding 20-25 years for asphalt shingles. Have a professional inspection if you notice any of these warning signs.
Building codes in many areas allow one layer of new shingles over existing ones. This saves $1,000-$3,000 in tear-off costs. However, adding weight can stress the structure, and hidden damage underneath goes undetected. Full tear-off is generally recommended.
Total Cost = (Roof Size x Material Cost/sqft x Region Multiplier x Story Multiplier) + Tear-off + Permits
Material costs include both materials and labor. Regional and story multipliers adjust for local market conditions.
