Licensing Requirements
Licensing Requirements
Montana requires roofers to be licensed through the Montana Department of Labor and Industry. Roofers must obtain a Class B General Contractor license or Class C Specialty Contractor license (Roofing). Requirements: proof of workers' compensation insurance, passing the Montana Contractor Examination (covers business law and trade knowledge), $25,000 bond for Class B or $10,000 bond for Class C, and documented work experience (typically 4+ years). No mandatory apprenticeship program, but practical experience verification is required. License renewal every 2 years with continuing education requirements (varies by license class). Exam passing score: 70% minimum.
Permit Requirements
Billings Building Department requires a roofing permit for all roof replacements, new construction, and repairs exceeding $2,500 in value. Permits require completed application, site plan, roofing material specifications, and contractor license verification. Permit fees typically $50-$150 based on project value (estimate based on local fee schedules). Inspection required before, during (if structural work involved), and after completion. Flat roofs and commercial work may require additional wind or load engineering documentation.
Inspection Schedule
Billings Building Department conducts inspections at three points: (1) Pre-work inspection to verify permits and site conditions (scheduled before work begins), (2) Mid-project inspection if structural work or decking replacement is involved (typically after framing exposed), (3) Final inspection upon completion before occupancy sign-off. Turn-around time for inspections: 2-3 business days. Inspector verifies code compliance, material specifications, flashing installation, ventilation requirements, and local wind load standards (Billings sits at 3,125 ft elevation with 90+ mph wind design requirements).
Insurance Minimums
Montana does not mandate specific insurance minimums for roofers, but industry standard and lender requirements are: General Liability minimum $1,000,000 per occurrence/$2,000,000 aggregate. Workers' Compensation required for any employees (statutory coverage). Property insurance covering tools and materials. Many commercial projects and municipalities require additional requirements: roofing contractors on public projects may need bonding (bid, performance, and payment bonds). Billings municipal contracts often require proof of $2,000,000 liability.

How to Get Licensed
Verify work experience and documentation
Gather proof of 4+ years roofing experience (employment letters, tax returns, project documentation). Montana Department of Labor and Industry requires documented practical experience. Self-employment with business records or W-2 employment letters from licensed contractors both count. This step typically takes 1-2 weeks to compile.
Obtain workers' compensation insurance
Contact a Montana-licensed insurance broker and apply for workers' compensation coverage. Proof of active policy is mandatory for license application. If you have no employees, you can request a waiver, but it's rarely granted for roofing contractors. Standard coverage runs $1,200-$2,500 annually depending on payroll estimates. Get proof of coverage in writing.
Secure a surety bond
Apply for a Class B ($25,000 bond) or Class C ($10,000 bond) surety bond through a bonding company. Provide personal financial statements, credit report authorization, and business plan. Bonding costs approximately 1-3% of bond value annually ($250-$750 for Class C, $750-$1,500 for Class B). Complete within 1-2 weeks if you have solid credit.
Register with Montana Department of Labor and Industry
Complete the Contractor License Application (Form CON-1) available on the Department of Labor and Industry website.

Schedule and pass the Montana Contractor Examination
Contact Pearson VUE (Montana's testing vendor) to schedule the Montana Contractor Examination. Exam covers business law, contract requirements, and trade-specific roofing knowledge. Study materials available through the Department of Labor and Industry website. Exam fee is approximately $50-$75. Passing score is 70% minimum. Schedule at least 2 weeks ahead for test availability.
Receive license approval and activation

License becomes effective immediately; you can legally bid and work in Montana. Register with Billings Building Department and local suppliers. Renewal requires continuing education (hours vary by license class) and fee payment before expiration.
About This Market
Billings roofing market runs steady year-round with clear seasonal swings. You've got 153 licensed roofing operations statewide—that's thin competition if you know how to bid. Demand spikes hard spring through fall; hail storms in May-June and late-season wind events drive emergency calls. Residential asphalt shingle work dominates the volume, but metal roofing is growing (homeowners like the longevity in Montana weather). Commercial flat roof work and gutter jobs fill gaps. Costs run $5-$8 per square foot for basic asphalt replacement, higher for metal or specialized work. Material costs track national markets but shipping adds 5-8% in this region. Elevation and wind loads bump structural requirements—Billings isn't flat country, and codes reflect that. Biggest cost drivers: labor availability (seasonal), material supply chain, roof complexity, and whether you're dealing with structural issues underneath.

What is the peak season for roofing in Billings?

Winter (November-March) is slower but storm damage and insurance claims keep work steady. Spring and early summer storms are predictable revenue—plan staffing and material supply accordingly.
What insurance do roofing contractors need in Montana?
Montana requires workers' compensation insurance for any employees (statutory). General Liability insurance minimum of $1,000,000 per occurrence/$2,000,000 aggregate is industry standard and required by most lenders and commercial projects. Billings municipal contracts often require $2,000,000 liability proof. Property insurance covering tools and materials is strongly recommended. Public projects may require performance and payment bonds in addition to liability.
Why are roofing costs higher in Billings?
Billings sits at 3,125 feet elevation with 90+ mph wind design load requirements, driving stronger structural specifications. Material shipping adds 5-8% versus lower-elevation markets. Labor availability swings seasonally—peak-season crew costs run 10-15% higher than winter rates. Metal roofing (increasingly popular for durability in Montana weather) costs 40-50% more than asphalt. Hail damage and complex roof geometries (common in regional architecture) increase labor time and material costs. Stock up materials before May if you want pricing certainty.
