Roofing contractors carry some of the highest operating costs in the trades, and the tax deductions reflect that. Materials, labor, workers’ compensation insurance (the highest rates of any trade), vehicle costs, and equipment depreciation make up the bulk of deductible expenses. The challenge is not finding deductions but tracking them correctly, separating cost of goods sold from operating expenses, and surviving the workers’ compensation audit.

✓Key takeaway

Major roofing contractor deductions:

Materials (cost of goods sold):

Shingles, underlayment, flashing, vents, drip edge, ice and water shield
Nails, screws, fasteners, caulk, roofing cement
Metal panels (for metal roofing)
Lumber for decking replacement
Dumpster rental for tear-off debris
Materials are COGS (deducted when used, not when purchased, if using accrual method)

Labor:

Crew wages (W-2 employees): fully deductible
Subcontractor payments (1099-NEC): fully deductible, but must issue 1099s for $600+
Overtime premium: deductible
Crew bonuses: deductible when paid (cash basis)

Workers’ compensation insurance:

Roofing carries the highest workers’ comp rates in construction: 20-40% of payroll in most states
On $400,000 in crew payroll: $80,000-$160,000 in workers’ comp premiums
Fully deductible as a business expense
The annual workers’ comp audit adjusts premiums based on actual payroll (track job classifications carefully)

Equipment (Section 179 or MACRS depreciation):

Work trucks and trailers: Section 179 if over 6,000 lbs GVWR (most roofing trucks qualify)
Boom trucks, cranes, man lifts: Section 179 in the first year or 5-year MACRS
Pneumatic nail guns, compressors: 5-year property
Ladders, scaffolding, safety harnesses: deductible as supplies or 5-7 year depreciable assets depending on cost
Magnetic nail sweepers: deductible as equipment

Vehicle costs:

Fuel for work trucks: deductible (actual method or standard mileage)
Vehicle insurance, registration, maintenance
Fleet vehicles: track business vs. personal use per vehicle
Most roofing trucks are 100% business use (dedicated work vehicles rarely driven personally)

Insurance (beyond workers’ comp):

General liability insurance: $2,000-$8,000/year, fully deductible
Commercial auto insurance: fully deductible
Inland marine (tools and equipment coverage): fully deductible
Umbrella/excess liability: fully deductible

Other deductions:

Safety training and OSHA compliance costs
Licensing and bonding fees
Estimating software (EagleView, Hover, CompanyCam)
Marketing (yard signs, truck wraps, Google Ads)
Office/shop rent
Warranty costs (repairs under warranty are deductible when performed)

What does a roofer’s first-year tax picture look like?

Hypothetical example

Round numbers. A roofing S-Corp in its first full year. Revenue: $800,000. Owner salary: $65,000.

Cost of goods sold:

Materials: $280,000 (35% of revenue, typical for roofing)
Crew wages: $200,000 (4-person crew)
Subcontractor payments: $40,000
Dumpster/disposal fees: $15,000
Total COGS: $535,000

Gross profit: $265,000

Operating expenses:

Workers’ comp insurance: $60,000 (30% of $200,000 payroll)
General liability insurance: $6,000
Commercial auto insurance: $8,000
Fuel and vehicle maintenance: $18,000
Equipment purchases (Section 179): $45,000 (truck: $35,000 + compressor: $5,000 + nail guns: $5,000)
Owner salary + employer FICA: $65,000 + $4,973 = $69,973
Office/shop rent: $12,000
Estimating software: $3,000
Marketing: $8,000
Phone, internet, supplies: $4,000
Licensing and bonding: $2,000
Total operating expenses: $235,973

Taxable income (K-1 to owner): $29,027

Owner’s tax on K-1:

Income tax (24%): $6,966
QBI deduction (20% x $29,027): reduces taxable by $5,805
Net tax on K-1 (after QBI): approximately $5,573
Owner’s W-2 taxes (income + FICA): approximately $20,000
Total tax: approximately $25,573

Key planning notes:

Workers’ comp is the largest non-payroll expense. Shop rates annually; a 5% rate difference on $200,000 payroll saves $10,000/year.
The Section 179 deduction on the truck ($35,000) saves approximately $8,400 in tax in Year 1.
Crew classification is critical. If any crew members are misclassified as 1099 contractors, the back-assessment for a single year could exceed $40,000 (employer FICA + penalties + state unemployment + back workers’ comp).
Track materials inventory carefully. If materials are purchased for one job but used on another, the cost shifts between jobs. For tax purposes on cash basis, materials are deductible when paid.
