The cost to roof an 800 sq ft area depends on materials, labor, location, and roof complexity. This guide explains how contractors price jobs, breaks down typical **cost ranges by material**, and offers actionable tips to estimate and reduce expenses for homeowners or property managers.
| Material | Typical Cost Per Sq Ft | Estimated Total For 800 Sq Ft |
|---|---|---|
| Aspahlt Shingles (3-tab) | $3.50 – $5.50 | $2,800 – $4,400 |
| Architectural Shingles | $4.50 – $7.50 | $3,600 – $6,000 |
| Metal Roofing (Panels) | $6.00 – $12.00 | $4,800 – $9,600 |
| Metal Roofing (Standing Seam) | $8.00 – $15.00 | $6,400 – $12,000 |
| TPO/EPDM (Flat Roof) | $4.00 – $9.00 | $3,200 – $7,200 |
| Ceramic Or Concrete Tile | $10.00 – $25.00 | $8,000 – $20,000 |
| Wood Shake | $7.00 – $14.00 | $5,600 – $11,200 |
How Roofers Measure And Price An 800 Sq Ft Roof
Roofing contractors use the roofing “square” where one square equals 100 sq ft. An **800 sq ft roof is 8 roofing squares**, so material and labor quotes are often calculated per square.
Quotes commonly list line items: materials, underlayment, flashing, fasteners, labor, tear-off/disposal, permit fees, and potential deck repairs. **Understanding each line item helps compare bids accurately.**
Material Cost Breakdowns
Aspahlt Shingles
Aspahlt shingles are the most common choice for U.S. homes due to affordability and ease of installation. **3-tab shingles are the lowest cost; architectural shingles offer better durability and aesthetics.** Typical lifespan: 15–30 years depending on quality and climate.
Metal Roofing
Metal is costlier upfront but can last 40+ years and reduce energy costs. **Standing seam metal is pricier than corrugated panels but provides superior durability and weather resistance.**
Flat Roof Membranes (TPO, EPDM, PVC)
For low-slope or flat 800 sq ft roofs, single-ply membranes like TPO or EPDM are common. **They offer good waterproofing and moderate lifespans of 15–30 years depending on product quality.**
Premium Materials: Tile, Slate, Wood Shake
Tile, slate, and wood shake are high-end options that significantly increase cost and structural requirements. **They may need reinforced decking and framing, which adds to total project cost.**
Labor, Tear-Off, And Additional Costs
Labor often equals or exceeds material cost, especially for complex roofs. **Tear-off and disposal typically add $1.00–$2.50 per sq ft, depending on layers removed and local landfill fees.**
Common additional expenses include permit fees, roof deck replacement, roof ventilation upgrades, fascia and soffit work, and gutter replacement. **Deck repairs can range from a few hundred dollars to several thousand if rot or structural damage is extensive.**
Regional Cost Factors And Seasonal Pricing
Labor and material prices vary regionally. Urban areas and regions with higher living costs see higher bids. **Weather and seasonality affect pricing—winter and early spring may offer lower demand and better rates in some areas.**
Transportation and material availability can raise costs in remote locations. **Hurricane-prone or snow-heavy regions may require specialized materials and fastening methods, increasing price.**
Example Price Calculations For 800 Sq Ft Roof
Here are sample scenarios to illustrate likely totals. All examples assume a simple gable roof with moderate pitch and one layer of old shingles removed.
| Scenario | Per Sq Ft | Estimated Total |
|---|---|---|
| Budget Asphalt (3-tab) | $3.50 | $2,800 |
| Mid-Range Architectural Shingles | $5.50 | $4,400 |
| Corrugated Metal Panels | $7.50 | $6,000 |
| Standing Seam Metal | $12.00 | $9,600 |
| TPO Single-Ply | $6.00 | $4,800 |
How To Get Accurate Estimates
Request at least three written bids from licensed local roofers. **Ensure each bid details material brand, underlayment type, number of layers removed, ventilation changes, and warranty terms.**
Ask for proof of insurance, references, and examples of similar 800 sq ft projects. **Avoid lowball bids that lack specifics or require large upfront cash payments.**
Permit Requirements And Inspection Costs
Most municipalities require permits for roof replacements. Permit cost varies widely but is commonly **$100–$500 for small residential jobs**; some areas base fees on job value.
Inspections may be required at stages like decking replacement and final completion. **Failing to pull permits can lead to fines or issues when selling the property.**
Warranties And Expected Lifespans
Manufacturer warranties vary: asphalt shingle warranties commonly range from 20 to 50 years for higher-end products, often prorated. **Workmanship warranties from contractors typically range 1–10 years.**
Understanding warranty transferability and what is covered is essential. **Warranties rarely cover damage from improper maintenance, storms, or third-party work.**
Financing Options And Insurance Considerations
Homeowners can use cash, home equity loans, HELOCs, personal loans, or contractor financing. **Some manufacturers and contractors offer financing plans with promotional rates.**
For storm damage, contact the homeowner’s insurance carrier first. **Insurance may cover partial or full replacement depending on your policy and cause of damage.**
Ways To Reduce The 800 Sq Ft Roof Cost
- Choose durable mid-range materials like architectural shingles to balance cost and longevity. **They often have better warranty value than cheap alternatives.**
- Schedule replacement in shoulder seasons to potentially secure lower labor rates. **Early spring or fall can be less busy for contractors.**
- Bundle projects—replacing gutters or soffits at the same time can reduce mobilization fees. **Contractors may offer package pricing.**
- Obtain permits and prepare the site to avoid delays and extra fees. **Clearing vegetation and providing safe access can speed work.**
Signs It’s Time To Replace An 800 Sq Ft Roof
Replace the roof if there is widespread shingle loss, sagging deck, persistent leaks, or when shingles are past their expected life. **Small isolated repairs may be cost-effective, but multiple problem spots often signal a full replacement is more economical.**
Regular inspections every few years help catch issues early. **A documented maintenance history can also help with resale value.**
Hiring And Contract Tips
Use a written contract that outlines start and end dates, payment schedule, change order procedures, cleanup responsibilities, and warranty coverage. **Verify contractor licensing, insurance, and local business registration.**
Holdback a final payment until work is inspected and permits closed. **Get lien waivers from subcontractors and suppliers to protect against future claims.**
Estimating For Complex Roofs And Unique Situations
Complex roofs with steep slopes, multiple penetrations, skylights, or dormers increase labor time and flashing requirements. **Expect 10–50% higher costs for complexity compared to a simple rectangular roof.**
Historic homes or structures requiring special materials or matching existing aesthetics will also increase both material and labor costs. **Specialty installers and custom fabrication drive up the price.**
Common Mistakes To Avoid
- Selecting a contractor solely on price without verifying credentials. **Low bids can hide inferior materials or workmanship.**
- Ignoring ventilation needs—poor ventilation shortens shingle life and can cause attic moisture problems. **Install or upgrade vents when replacing the roof if necessary.**
- Skipping proper underlayment and flashing—these components are critical for preventing leaks. **Invest in quality underlayment and professional flashing installation.**
Key Takeaways For 800 Sq Ft Roof Cost Planning
For an 800 sq ft roof, homeowners should expect a wide price range depending on material choice and project complexity. **Budget estimates typically range from $2,800 for basic asphalt to $12,000 or more for premium metal or tile installations.**
Gather multiple detailed bids, confirm warranties and permits, and plan for contingencies like deck repair. **Careful planning yields the best balance of cost, performance, and long-term value.**
Helpful Resources: Consult the National Roofing Contractors Association (NRCA) and local building departments for standards and permit guidance. Contact at least three local installers for itemized quotes and timelines.
