A 600 square foot roof is relatively small compared to the average American home roof, which typically ranges from 1,500 to 2,000 square feet. This size roof might cover a structure approximately 20′ x 30′, though the actual building footprint may be smaller due to roof overhangs, pitch, and design complexity.
Roofers typically measure in “squares,” with one square equaling 100 square feet. Therefore, a 600 square foot roof equals 6 roofing squares. Understanding this industry terminology is helpful when obtaining and comparing quotes from contractors.
Common structures with approximately 600 square feet of roofing include:
- Two-car garages
- Small cottages or tiny homes
- Home additions or extensions
- Large sheds or workshops
- Small retail storefronts

| Wood Shakes | $4.00-$6.00 | $2,400-$3,600 |
| Concrete/Clay Tiles | $5.00-$7.00 | $3,000-$4,200 |
| Slate | $6.00-$8.00 | $3,600-$4,800 |
Roof Tear-Off and Disposal Costs
Removing an existing roof adds approximately $1.00-$2.00 per square foot ($600-$1,200 for 600 sq ft) to the project cost. Multiple layers of old roofing increase this expense. Disposal fees vary by region and roofing material weight, typically ranging from $250-$500 for a 600 square foot roof.
Some materials like asphalt shingles can sometimes be recycled, potentially reducing disposal costs. Metal roofing scrap may have salvage value that offsets some removal expenses.
Additional Costs and Considerations
Beyond basic materials and installation labor, several other factors contribute to the total cost of a 600 square foot roofing project.
Underlayment and Waterproofing
Underlayment costs range from $0.20-$0.80 per square foot ($120-$480 for 600 sq ft) depending on quality. Standard felt underlayment is most economical, while synthetic underlayments offer superior protection at a higher price point.
In areas with severe weather or for low-slope sections, self-adhering waterproof underlayment (ice and water shield) may be recommended at $0.60-$1.00 per square foot. Most building codes require enhanced waterproofing in valleys and near roof edges.
Roof Deck Repairs
If roof decking (plywood or OSB sheathing) needs replacement, this adds significant cost. New decking materials cost $2.00-$3.50 per square foot plus labor. For a 600 square foot roof, replacing 25% of the decking would add approximately $450-$800 to the project.
Structural repairs to rafters or trusses are additional expenses that may only be discovered once the old roofing is removed. Setting aside a contingency budget of 10-15% is advisable for older structures.
Flashing and Accessories
Metal flashing for roof penetrations, valleys, eaves, and transitions is essential for preventing leaks. For a 600 square foot roof, expect to spend $200-$500 on basic flashing materials, depending on the number of penetrations and complexity.
Ridge vents, drip edges, pipe boots, and other accessories add approximately $1.00-$2.00 per square foot to the total material cost, or $600-$1,200 for a 600 square foot roof.
Permits and Inspections
Most municipalities require building permits for roof replacements. Permit costs vary widely by location but typically range from $100-$500 for a 600 square foot roof project. Some areas may also require inspection fees in addition to the permit costs.
Professional roofing contractors typically handle the permitting process as part of their service, but homeowners should verify this is included in project quotes.
Cost Comparison by Roof Style and Pitch
Roof configuration significantly impacts the total cost of a roofing project, even when covering the same square footage.
Roof Pitch Impact on Pricing
Steeper roofs typically cost 20-40% more than low-pitch roofs due to increased safety requirements, greater material needs, and more challenging installation. For a 600 square foot roof:
| Roof Pitch | Price Factor | Example Cost (Asphalt) |
|---|---|---|
| Low (2:12 to 4:12) | Base price | $3,000-$3,600 |
| Medium (5:12 to 8:12) | +10-20% | $3,300-$4,320 |
| Steep (9:12 to 12:12) | +25-40% | $3,750-$5,040 |
| Very Steep (>12:12) | +40-60% | $4,200-$5,760 |
Roof Complexity Factors
A simple gable roof is the most economical design, while complex roofs with multiple facets, valleys, dormers, or level changes cost more to roof, even with identical square footage. Each roof valley adds approximately $100-$200 to a project, while dormers or skylights can add $200-$500 each.
For a 600 square foot roof, the price difference between a simple gable design and a complex multiple-pitch design with dormers can be 30-50%, even using the same roofing material.
Regional Price Variations
Roofing costs vary significantly across different regions of the United States. The same 600 square foot asphalt shingle roof project might cost 30-60% more in high-cost areas compared to lower-cost regions.
| Region | Relative Cost | 600 sq ft Asphalt Roof |
|---|---|---|
| Midwest | Lower | $3,000-$4,200 |
| South | Lower-Moderate | $3,300-$4,500 |
| Northeast | Moderate-High | $4,200-$5,400 |
| West Coast | High | $4,800-$6,600 |
Weather considerations also impact material recommendations and installation requirements by region. Hurricane-prone areas may need enhanced attachment methods, while northern regions require materials suited for heavy snow loads and freeze-thaw cycles.
Urban vs. Rural Cost Differences
Urban areas typically have higher roofing costs than rural areas due to higher labor rates, increased overhead for contractors, and more stringent permit requirements. Expect to pay 15-25% more for the same roofing project in a major metropolitan area compared to a rural location.
However, remote rural locations may incur additional travel charges if contractors must travel significant distances to reach the property. These travel surcharges can add $200-$500 to a 600 square foot roofing project.
DIY vs. Professional Installation Costs
Some homeowners consider DIY roof installation to save on labor costs, which typically represent 40-60% of a roofing project’s total expense.
Material Costs for DIY Projects
DIY roofing requires purchasing all the same materials a professional would use. For a 600 square foot roof, DIY material costs typically range from $1,800-$7,200 depending on the roofing material selected.
DIY projects also require specialized tools like roofing nailers, tear-off tools, ladders, safety equipment, and more. Tool purchases or rentals can add $300-$1,000 to a DIY project cost.
Hidden Costs of DIY Roofing
While DIY installation eliminates direct labor costs, several hidden expenses and drawbacks should be considered:
- No professional warranty on installation (typically 5-10 years)
- Potential voiding of material manufacturer warranties
- Significant time investment (typically 3-7 days for amateurs)
- Safety risks and potential for injury
- Potential for mistakes requiring professional repair
DIY mistakes can lead to water damage costing far more than the original labor savings. Most roofing professionals recommend against DIY installation for all but the simplest shed or outbuilding roofs.
Maintenance Costs and Long-Term Value
When evaluating roofing options for a 600 square foot roof, considering long-term costs beyond initial installation provides a more accurate picture of true ownership costs.
Lifespan and Replacement Frequency
Long-lasting materials like slate, clay tile, or high-end metal roofing can significantly reduce lifetime costs despite higher initial investments. For a 600 square foot roof, the lifetime cost comparison over 75 years might look like:
| Material | Lifespan | Replacements in 75 Years | Total 75-Year Cost |
|---|---|---|---|
| 3-Tab Asphalt | 15-20 years | 3-5 | $12,000-$20,000 |
| Architectural Asphalt | 25-30 years | 2-3 | $9,000-$13,500 |
| Metal Roofing | 40-70 years | 1-2 | $8,400-$18,000 |
| Clay Tile | 50+ years | 1-2 | $11,400-$22,800 |
| Slate | 75+ years | 0-1 | $12,000-$18,000 |
Maintenance Requirements by Material
Different roofing materials require varying levels of maintenance, affecting long-term ownership costs:
- Asphalt shingles: Periodic inspection, occasional shingle replacement, $100-$300 every 3-5 years
- Metal roofing: Minimal maintenance, occasional fastener tightening, $75-$200 every 5 years
- Wood shakes: Regular cleaning, preservative treatments, $200-$500 every 2-3 years
- Clay/concrete tiles: Occasional broken tile replacement, $150-$350 every 5-10 years
- Slate: Minimal maintenance, occasional slate replacement, $200-$400 every 10 years
Saving Money on Your 600 Square Foot Roof Project
Several strategies can help reduce costs while maintaining quality for a 600 square foot roof replacement:
Timing Your Project
Scheduling roof installation during the off-season (late fall through early spring in most regions) can save 10-15% on labor costs. Roofing contractors often offer discounted rates during slower periods to keep crews working.
Combining your roof project with neighbors who also need roof work can sometimes yield group discounts of 5-10% as contractors save on setup, material delivery, and travel costs.
Material Selection Strategies
Consider these cost-saving approaches when selecting roofing materials:
- Choose architectural shingles instead of premium designer shingles for similar aesthetics at lower cost
- Opt for synthetic slate or shake alternatives rather than natural materials (50-60% cost savings)
- Consider metal roofing in standard colors rather than custom finishes (10-20% savings)
- Look for manufacturer discontinuations or overstock sales (potential 15-30% savings)
Most roofing manufacturers offer good-better-best product lines with similar appearance but different warranty lengths and features. For smaller structures, mid-range products often provide the best value balance.
Contractor Selection Tips
Getting multiple quotes (ideally 3-5) from reputable contractors is essential for price comparison. When evaluating bids for a 600 square foot roof:
- Ensure quotes include the same scope of work and specifications
- Verify contractor licensing, insurance, and warranty offerings
- Check references and online reviews for quality assurance
- Ask about material sourcing and potential volume discounts
The lowest bid isn’t always the best value. Prioritize contractors using quality materials with strong workmanship warranties and proper licensing over those offering significantly lower prices than competitors.
Tax Credits and Incentives
Energy-efficient roofing materials may qualify for federal tax credits, local rebates, or utility incentives. ENERGY STAR-rated roofing can qualify for up to 10% of material costs (maximum $500) in federal tax credits while providing ongoing energy savings.
Some insurance companies offer policy discounts of 5-25% for impact-resistant roofing in hail-prone regions. These savings can significantly offset the premium costs of upgraded roofing materials over time.
