This guide explores requirements, profitability, job scope, and demand, helping you make an informed decision in 2025. We've listed and analysed every aspect to help you find your ideal career path.

Overview of Residential vs Commercial Roofing

Here's a quick overview of the differences between residential and commercial roofing:

Aspect Residential Roofing Commercial Roofing
Required Licenses Limited license under the Illinois Roofing Industry Licensing Act. Unlimited or Commercial license required for larger projects.
Insurance Costs Lower requires standard liability and workers’ compensation. Higher requires larger policies, bonding, and coverage limits.
Profit Margins Net margins average 10 to 20%. Net margins average 8 to 15%, depending on management.
Average Payouts $6,000 to $20,000 per home roof replacement. $50,000+ for larger commercial or industrial projects.
Payout Cycles Short, fast turnarounds. Longer progress-based payments.
Risk Level Moderate, mainly weather and homeowner disputes. Higher because of contractual liability and safety risks.
Investment Requirement Lower requires basic trucks and tools. Higher requires equipment, lifts, and safety systems.

Quick Answer: Residential roofing is quicker with better profit margins, but seasonal and lower payouts. Commercial roofing is riskier, longer, and has lower profit margins, but better payouts and long-term feasibility.

Requirements of Residential vs Commercial Roofing

All roofers must hold a roofing license according to the Illinois Roofing Industry Licensing Act. Roofers can choose between a Limited or Unlimited Roofing License, depending on their needs. Here's a quick overview of the licenses:

  • Limited License (Residential): These allow you to work on residential properties that contain 8 or fewer units.
  • Unlimited License (Commercial/Industrial): Allows you to work on commercial, industrial, and residential projects irrespective of size.

A residential roofer with a Limited License cannot work on a commercial project. Both licenses have separate exams, requirements, and job scopes. Other requirement differences include:

  • Surety Bonds: Residential roofing requires a surety bond of $10000, while commercial roofing and licenses require a $25000 surety bond.
  • Insurance Costs: Commercial roofing has 20% to 80% higher insurance costs than residential roofing.
  • Material Costs: Commercial roofing projects require more specialized materials, making them more investment-intensive.

Residential work typically requires smaller insurance limits. Commercial contractors must carry higher limits and often need bonds for public or industrial projects.

Profitability of Commercial vs Residential Roofing

Residential roofing brings faster cash flow and simpler management. Commercial roofing offers better payouts but drawn-out cash flows. Here's the profitability compared:

Residential Roofing Profitability

Illinois roofers make $27.59 per hour on average, while contractor billing rates reach about $85 per hour (including overhead). Most roofing companies see gross margins of 20 to 40% and net profits of 10 to 20% per residential project.

Residential roofing projects offer three distinct advantages:

  • Shorter Projects: Residential projects usually range from 1 to 10 days, making them quick cash grabs.
  • More Profit Margins: These projects have better margins, meaning you earn per time and money invested.
  • Low Investments: Residential projects are easier to come by and require lower investments.

The quicker payouts make residential projects great avenues for new businesses. It gives you liquid cash to expand the business more quickly.

Commercial Roofing Profitability

Commercial roofing involves larger contracts but also higher risk and slower payments. Typical installation costs for membranes like TPO or EPDM range from $4 to $9 per square foot. Commercial roofing net margins often range between 8% and 15% depending on management and bid accuracy.

In a 2025 survey, 68% of commercial contractors reported higher sales volume, and 80% expect further growth. While commercial roofing has bigger but delayed payouts. These projects also require higher material and insurance investments.

We recommend focusing on commercial roofing projects when you have:

  1. Established business reputation
  2. Great capital for expansion
  3. Enough skilled workers

Individuals cannot cope with the taxing demands of commercial roofing.

Job Scope of Residential and Commercial Roofing

Residential and commercial roofing jobs have similar scopes. The main difference is the type of material and scale of each job. Residential roofing projects are limited to a single house, while commercial buildings are much larger with greater requirements.

Here's how each compares to the other:

Residential Job Scope

Residential work covers steep-slope systems, primarily asphalt shingles, tiles, and wood. These dominate more than 55% of the roofing materials market. Tasks include tear-offs, shingle installation, flashing, and gutter repair.

Residential roofing requires a more varied experience with different roofing systems. The requirements can shift drastically from one job to another. 

Commercial Job Scope

The materials used in commercial projects include TPO, EPDM, PVC, Modified Bitumen, or metal. Flat and low-slope systems accounted for 56.8% of industry revenue in 2024. About 94% of commercial roofing activity is re-roofing rather than new builds.

Property owners often have similar requirements across different commercial projects. This happens because of building codes and standards. 

Demand for Commercial vs Residential Roofing

Residential roofing held nearly 60% of the total U.S. roofing market share in 2024. Storm recovery, aging homes, and energy-efficient roof replacements fuel steady growth. Around 77% of residential contractors expect sales growth through 2027.

The commercial roofing market continues to expand, with forecasts showing a 7.35% CAGR through 2030. Around 83% of commercial roofers expect growth in the next three years, driven by re-roofing cycles, energy regulations, and facility upgrades.

When compared side-by-side, residential roofing has more demand with seasonal spikes. Roofers can expect a huge spike in demand after storms or volatile weather. Commercial roofing is more monotone but follows the same seasonal spike.

Illinois Roofer Outlook

Illinois employs roughly 6,000 to 6,100 roofers statewide. Both residential and commercial markets remain active, especially around Chicago and urban centers with older building inventories.

Most roofers work on both types of professional roofing projects. While the number of specific license holders isn't public, we believe 65% of roofers hold an unlimited license.
