Roofing has the highest material cost of any common trade business. On a typical residential shingle replacement, materials (shingles, underlayment, drip edge, flashing, ridge vent, nails, ice and water shield) consume 40-50% of the contract price. This distinguishes roofing from service-heavy trades (plumbing, electrical, HVAC) where materials run 15-30%. The second major cost is workers’ compensation insurance: NCCI code 5551 (roofing) is one of the most expensive classifications in any industry, reflecting the high injury risk of working at height. Rates run 10-20% of payroll depending on the state and the company’s experience modification (mod) rating. A clean safety record with a mod rating below 1.0 can cut workers’ comp costs by 15-30%.

✓Key takeaway

Roofing deductions by category:

Materials (40-50% of revenue):

Material	Cost per Roof (avg)	% of Material Total
Shingles (architectural)	$2,000-$3,500	40-50%
Underlayment (synthetic)	$300-$600	6-10%
Ice and water shield	$200-$500	4-8%
Drip edge (aluminum)	$100-$250	2-4%
Flashing (step, valley, pipe boots)	$150-$400	3-6%
Ridge vent	$100-$300	2-5%
Nails (coil, cap)	$100-$200	2-3%
Starter strip	$50-$150	1-2%
Caulk/sealant	$30-$80	1%
Total per roof	$3,030-$5,980	100%

On a $12,000 residential roof replacement: materials = $4,500-$5,500 (38-46%).

Premium materials (higher revenue AND higher material cost):

Material	Cost per Roof	Typical Contract
Architectural shingles	$2,500-$3,500	$10,000-$15,000
Designer/luxury shingles	$4,000-$7,000	$15,000-$25,000
Standing seam metal	$6,000-$12,000	$20,000-$35,000
Cedar shake	$5,000-$10,000	$18,000-$30,000
Slate (natural)	$10,000-$25,000	$30,000-$60,000
TPO/EPDM (commercial)	$3-$6/sq ft	$8,000-$20,000

Workers’ comp (NCCI 5551):

Base rate: 10-20% of payroll (varies by state)
Experience mod below 1.0: reduces premium by the same percentage
Example: 15% base rate, 0.85 mod = 12.75% effective rate
On $120,000 payroll: $15,300 at base rate, $12,750 at 0.85 mod
Savings from good safety: $2,550/year on this payroll level
Every workplace injury increases the mod for 3 years

Dump and disposal (unique to roofing):

Dumpster rental (20-yard, per roof): $300-$600
Landfill tipping fees (per ton): $40-$80
Shingle recycling (where available): $25-$50/ton (cheaper than landfill)
Average disposal cost per residential tear-off: $400-$800
Annual disposal on 40 roofs: $16,000-$32,000 (2-4% of revenue)

Equipment ($40,000-$80,000):

Equipment	Cost	Section 179
Truck (F-250/F-350)	$35,000-$60,000	Yes (over 6,000 lbs)
Dump trailer (for debris)	$5,000-$15,000	Yes
Roofing nailers (2-3)	$600-$1,800	Yes
Compressor (portable)	$500-$2,000	Yes
Shingle elevator/hoist	$3,000-$8,000	Yes
Safety harnesses/equipment	$500-$2,000	Yes
Ladders (extension, 28-40’)	$500-$2,000	Yes
Scaffold set	$1,000-$3,000	Yes
Metal brake (for flashing)	$500-$2,000	Yes

Insurance (high relative to other trades):

Workers’ comp: see above (10-20% of payroll)
General liability: $3,000-$8,000/year (higher than most trades)
Commercial auto: $2,000-$5,000/year
Inland marine (tools/equipment): $500-$1,500/year
Builder’s risk (if applicable): $500-$2,000/year
Total non-workers-comp insurance: $6,000-$16,500/year

Marketing:

Google Ads (roofing + city): $1,000-$5,000/month (competitive)
Yard signs: $200-$500 (high ROI for referrals)
Door-to-door (storm damage): $0 cost, highest conversion in roofing
Website/SEO: $500-$2,000/month
Total: $15,000-$50,000/year (roofing is one of the most expensive Google Ads verticals)

What does a full-year deduction breakdown look like?

Hypothetical example

Round numbers. A roofing company with 3 employees. Year 2 (truck depreciated). 40 residential roofs/year. Revenue $500,000.

Deductions:

Category	Amount	% of Revenue
Materials	$210,000	42.0%
Employee wages	$120,000	24.0%
Workers’ comp (14% of payroll)	$16,800	3.4%
Employer FICA	$9,180	1.8%
Dump/disposal	$20,000	4.0%
Truck/vehicle expenses	$12,000	2.4%
Insurance (GL + auto + inland marine)	$10,000	2.0%
Equipment maintenance	$4,000	0.8%
Marketing/advertising	$8,000	1.6%
Office/admin	$3,000	0.6%
Phone/software	$2,000	0.4%
Total	$414,980	83.0%

Net profit: $85,020

At 83% total expenses, roofing has one of the thinnest margins of any trade business. Compare:

Mobile car wash: 16% expenses, 84% margin
Landscaping (solo): 32% expenses, 68% margin
Snow removal: 38% expenses, 62% margin
Roofing (crew): 83% expenses, 17% margin

This thin margin means:

The S-Corp election saves less in absolute dollars (there’s less profit to shelter)
Material waste directly erodes margins (5% waste on $210,000 = $10,500 lost)
Workers’ comp management is critical (the difference between a 0.85 and 1.2 mod = $5,880/year)
Every supplemented insurance claim directly improves profit

Material waste management: Typical shingle waste: 10-15% on a hip roof (most cuts), 5-8% on a gable roof (fewer cuts). Annual waste at 12%: $210,000 x 12% = $25,200 in waste material.

Reducing waste to 8% through better crew training and cutting practices: $210,000 x 8% = $16,800 in waste. Savings: $8,400/year.

This savings is taxable profit (reducing a deductible expense), but the cash flow impact ($8,400 more in your pocket) far exceeds the tax cost of the additional income ($8,400 x 22% = $1,848). Net gain: $6,552.

Shingle purchasing strategy: Buying direct from a distributor vs. retail:

Big box: $95-$110/bundle (3-tab), $120-$140/bundle (architectural)
Distributor: $75-$90/bundle, $95-$115/bundle
Volume contract (1,000+ squares/year): $70-$85/bundle, $90-$105/bundle

On 40 roofs using ~30 squares each = 1,200 squares = 3,600 bundles:

Retail: $432,000-$504,000
Distributor: $342,000-$414,000
Volume: $324,000-$378,000

Potential savings: $54,000-$126,000/year by moving from retail to volume purchasing.
