What Is Roll Roofing And Where It’s Used

Roll roofing is a rolled membrane typically made from asphalt-saturated felt or fiberglass with mineral granules on the surface. It’s designed for roofs with low slopes where typical shingle installation is impractical. It’s commonly used on accessory buildings, carports, and low-slope residential roofs.

Common Types Of Roll Roofing And Their Costs

Roll roofing comes in multiple materials and grades; each affects price and longevity. Choice of material is a primary driver of total cost and performance.

• Asphalt-Saturated Felt (Traditional): Least expensive, often $40–$70 per 100 ft roll; short lifespan and higher maintenance.
• Mineral-Surfaced Asphalt Roll: Similar to rolled shingles with granules, $50–$100 per roll; better UV protection and durability.
• Modified Bitumen Roll Roofing: Higher-end with rubberized modifiers, $80–$160 per roll; longer life and better waterproofing.
• Peel-and-Stick Rolls: Self-adhesive membranes for easier weatherproofing, $100–$200 per roll; useful for DIY and critical seams.

How Contractors Price Roll Roofing Jobs

Contractors typically price roll roofing by the square (100 square feet) or by linear foot for simpler roof runs. Labor, roof complexity, tear-off and disposal, and material brand influence final quotes significantly.

Pricing Component	Typical Range
Material Per Square	$40 – $160
Labor Per Square	$60 – $150
Tear-Off & Disposal	$20 – $60 Per Sq
Flashing & Accessories	$30 – $120+ Per Job

Installation Cost Factors To Consider

Several variables change installation costs, including roof size, pitch, number of penetrations, and access. Complexity and safety requirements often increase labor rates and total cost.

• Roof Size And Shape: More seams and cuts increase time and waste.
• Roof Pitch And Height: Steeper or high roofs require fall protection and raise labor cost.
• Number Of Penetrations: Vents, chimneys, and skylights require more flashing work.
• Existing Roofing Removal: Tear-off of old material adds disposal fees and labor.
• Local Labor Rates: Urban markets usually have higher hourly rates than rural areas.

DIY Versus Professional Installation

Roll roofing is often promoted as DIY-friendly, but trade-offs exist. DIY saves labor but may void warranties and reduce lifespan if improperly installed.

• DIY Pros: Lower immediate cost; suitable for small, low-risk projects like sheds.
• DIY Cons: Safety risks, potential for leaks, and lack of professional flashing and sealing.
• Professional Pros: Faster, certified techniques, warranty coverage, and proper detailing.
• Professional Cons: Higher upfront cost but often better long-term value and fewer callbacks.

Lifespan, Maintenance, And Long-Term Costs

Roll roofing generally has a shorter lifespan than architectural shingles or metal roofs. Expect 5–20 years depending on material quality and installation.

• Lower-End Asphalt Felt: 5–10 years; vulnerable to UV and temperature cycling.
• Mineral-Surfaced Rolls: 8–15 years with moderate maintenance.
• Modified Bitumen: 12–20 years when well-installed and maintained.

Maintenance tasks—seasonal inspections, prompt patching, clearing debris—can extend life and prevent costly leaks. Neglect accelerates deterioration and increases replacement frequency.

Cost Comparison: Roll Roofing Vs. Alternatives

Choosing roll roofing depends on budget and expected service life. Understanding comparative costs helps homeowners weigh short-term savings against long-term value.

Roof Type	Installed Cost Per Sq	Typical Lifespan
Roll Roofing	$100 – $270	5 – 20 Years
Asphalt Shingles	$150 – $400	20 – 30 Years
Metal Roofing	$300 – $900	30 – 70 Years

How To Estimate Roll Roofing Costs For A Project

Estimating requires accurate roof measurements and a material plus labor calculation. Follow a stepwise method to produce a realistic budget.

1. Measure Roof Area: Multiply roof length by width for each plane, then sum. Convert to squares (divide total sq ft by 100).
2. Choose Material Grade: Select expected roll type and check manufacturer coverage per roll.
3. Account For Waste And Seams: Add 10–15% for waste on irregular roofs.
4. Get Local Labor Rates: Request quotes from 2–3 contractors to compare.
5. Include Tear-Off & Disposal: Don’t forget removal fees if replacing existing roofing.

Practical Examples And Sample Estimates

Examples clarify pricing for common scenarios. These sample estimates use national averages; local prices will vary.

• Small Garage Roof (300 sq ft | 3 squares): Material $120–$450; labor $180–$450; total $300–$900.
• Accessory Building (1,000 sq ft | 10 squares): Material $400–$1,600; labor $600–$1,500; total $1,000–$3,100.
• Low-Slope House Addition (2,000 sq ft | 20 squares): Material $800–$3,200; labor $1,200–$3,000; total $2,000–$9,200.

Ways To Save Money Without Sacrificing Performance

Cost savings are possible with careful planning. Strategic choices can reduce total cost while maintaining adequate protection.

• Shop Multiple Suppliers: Compare brands and bulk pricing for rolls and accessories.
• Bundle Projects: Combine nearby small roofs into one contractor visit to reduce mobilization fees.
• Repair Rather Than Replace: For limited damage, targeted patches can be far cheaper.
• Choose Durable Upgrades Selectively: Invest in higher-quality flashing and waterproofing at critical areas rather than upgrading entire roof.

Permits, Warranties, And Insurance Considerations

Permitting and warranties affect both upfront cost and long-term protection. Confirm permit requirements and warranty coverage before committing to a contractor or product.

• Local Permits: Many municipalities require permits for roof replacement—check local building codes.
• Manufacturer Warranties: Warranty terms vary by material and installation method; some warranties require professional installation.
• Insurance Claims: If damage is storm-related, consult the insurer before repairs and document damage thoroughly.

Key Takeaways For Homeowners Considering Roll Roofing

Roll roofing remains a viable budget option for low-slope and secondary roofs. Understanding material types, labor factors, and lifecycle costs enables better budgeting and smarter decisions.

Homeowners should compare quotes, consider long-term durability versus short-term savings, and ensure proper flashing and installation to avoid premature failures. Professional installation often yields better long-term value despite higher initial cost.

Frequently Asked Questions

Is Roll Roofing A Good Choice For A House?

Roll roofing can be appropriate for low-slope sections or outbuildings but is generally not recommended as the primary roofing material for main residential roofs due to shorter lifespan. Consider higher-durability options for primary living areas.

How Long Does Roll Roofing Last?

Lifespan ranges from about 5 years for basic asphalt felt to 20 years for high-quality modified bitumen products. Quality of installation and maintenance greatly affects longevity.

Can Roll Roofing Be Installed Over Existing Roofing?

In some cases, roll roofing can be installed over an existing surface, but local codes and roof condition often require tear-off. Tear-off is usually recommended for best results and warranty compliance.

How To Find A Reliable Contractor?

Ask for licensed references, check online reviews, verify insurance, and request detailed written estimates with material specs and warranty terms. Comparing multiple bids helps identify fair pricing and expertise.

For accurate project budgeting, obtain local material pricing and at least two professional estimates based on measured roof dimensions and specific material choices.
