Your roof is one of the most critical components of your home, protecting your family and belongings from the elements. Whether you need roof repairs, a complete replacement, or new construction roofing, choosing the right roofing contractor is essential for quality workmanship, fair pricing, and long-term protection. Before you hire a roofer, ask these important questions to ensure you’re making the best decision.
Table of Contents
1. Are You Licensed, Insured, and Bonded?
This is the most important question to ask any roofing contractor.
Roofing is dangerous work, and proper licensing and insurance protect both you and the workers on your property.
What to verify:
- Valid contractor’s license for your state (check with your state licensing board)
- General liability insurance (protects against property damage)
- Workers’ compensation insurance (covers injured workers)
- Bonding (guarantees project completion)
- Proof of insurance certificate (request a current copy)
Warning: If a roofer falls and gets injured on your property and they don’t have workers’ comp insurance, you could be held liable. Never skip this verification step.
2. How Long Have You Been in the Roofing Business?
Experience matters in roofing. A contractor with years of experience has handled various roof types, weather conditions, and unexpected problems.
Ask about:
- Years in business under their current company name
- Experience with your specific roof type (asphalt shingle, metal, tile, flat, etc.)
- Familiarity with your climate and local weather challenges
- Types of properties they typically work on (residential vs. commercial)
- Recent projects similar to yours
Red flag: Be cautious of contractors who can’t provide a solid work history or frequently change business names.
3. Can You Provide Local References and Examples of Recent Work?
Reputable roofing contractors should readily provide references from recent customers in your area.
What to request:
- At least 3-5 recent references (ideally with similar projects)
- Contact information for past customers
- Addresses of recent jobs you can drive by
- Before and after photos of completed projects
- Online reviews (Google, Yelp, Better Business Bureau, Angi)
Follow up: Actually call the references and ask about their experience, quality of work, timeliness, cleanup, and any issues that arose.
4. Will You Provide a Detailed Written Estimate?
A professional roofing contractor provides comprehensive, itemized estimates before starting work.
The estimate should include:
- Exact scope of work (tear-off, replacement, repairs)
- Roofing materials specifications (brand, type, color, warranty)
- Underlayment and ice/water shield details
- Flashing, vents, and accessory materials
- Labor costs
- Removal and disposal of old roofing materials
- Cleanup procedures
- Project timeline (start and completion dates)
- Total cost breakdown
- Payment schedule
- Warranty information (both materials and workmanship)
Pro tip: Get at least 3 written estimates from different roofing contractors. Compare not just price, but materials quality, warranty terms, and scope of work.
5. What Type of Roofing Material Do You Recommend and Why?
An experienced roofer should help you choose the best roofing material for your climate, budget, and home style.
Common roofing materials:
- Asphalt shingles: Most common, affordable, 20-30 year lifespan
- Architectural shingles: Thicker, more durable, better curb appeal, 30-50 years
- Metal roofing: Long-lasting (40-70 years), energy-efficient, higher upfront cost
- Tile roofing: Excellent for hot climates, 50-100 years, heavy, expensive
- Slate roofing: Premium option, 75-150 years, very expensive
- Flat/TPO/EPDM: For flat or low-slope roofs
Ask: “Based on my climate, home style, and budget, what do you recommend?” A good contractor explains options honestly rather than pushing the most expensive choice.
6. What Manufacturer Certifications Do You Have?
Many roofing manufacturers offer certification programs for contractors who meet their standards.
Why certifications matter:
- Access to better warranty coverage
- Specialized training on proper installation
- Higher quality standards
- Extended warranty options
- Better manufacturer support
Major manufacturers: GAF, CertainTeed, Owens Corning, IKO, Tamko, and others offer certification programs. Ask which manufacturers the contractor is certified with.
7. What Warranties Are Included?
Roofing warranties are complex—you typically get two separate warranties.
Types of warranties:
Manufacturer’s Material Warranty:
- Covers defects in roofing materials
- Typically 25-50 years depending on product
- May be prorated or non-prorated
- Only valid if installed correctly
Contractor’s Workmanship Warranty:
- Covers installation errors and labor
- Typically 1-10 years (longer is better)
- Should be in writing
- Verify what’s covered and excluded
Critical questions:
- How long is your workmanship warranty?
- What does it cover?
- Is the warranty transferable if I sell my home?
- Will you provide the warranty in writing?
- What voids the warranty?
8. Will You Pull the Necessary Permits?
Most roof replacements and major repairs require building permits.
Why permits matter:
- Ensures work meets local building codes
- Required for homeowner’s insurance claims
- Necessary for home resale
- Protects you from shoddy work
Ask:
- Will this project require a permit?
- Who obtains the permit—you or me?
- Is the permit cost included in your estimate?
- Who schedules the inspection?
- What happens if work doesn’t pass inspection?
Red flag: A contractor who suggests skipping permits to “save money” is cutting corners and potentially doing illegal work.
9. What Is Your Project Timeline?
Understanding the timeline helps you plan and sets clear expectations.
Discuss:
- When can you start?
- How long will the project take? (Most residential roofs: 1-3 days)
- How many crew members will work on my roof?
- Will you work consecutive days or intermittently?
- What could cause delays? (weather, material shortages, etc.)
- What happens if bad weather interrupts the project?
Weather considerations: Roofing requires dry conditions. Ask how rain or storms will be handled and how your home will be protected if work is interrupted.
10. How Will You Protect My Property?
Roofing is messy work. A professional contractor takes steps to protect your property and minimize disruption.
They should:
- Use tarps to protect landscaping and gardens
- Place plywood over AC units and fragile items
- Use magnetic rollers to pick up nails and metal debris
- Set up dumpsters or trailers for debris removal
- Protect siding, windows, and gutters
- Do a thorough final cleanup
- Inspect gutters after completion
Ask: “What’s your cleanup process?” and “How do you protect my landscaping and property?”
11. Will You Do the Work or Subcontract It?
Know who will actually be on your roof.
Important questions:
- Will you personally oversee the project?
- Do you use your own employees or subcontractors?
- Are all workers covered by insurance?
- Who is my point of contact during the project?
- Will the same crew work throughout, or will different teams rotate?
Note: Using subcontractors isn’t necessarily bad, but you should know who’s working on your home and verify they’re properly insured and experienced.
12. What Happens If You Find Unexpected Damage?
Roofing projects often reveal hidden problems—rotted decking, structural issues, or code violations.
Clarify:
- How will unexpected issues be handled?
- Will you notify me before doing additional work?
- How are change orders documented and priced?
- What if major structural problems are discovered?
- Are there common issues with roofs like mine?
Best practice: Any additional work should be approved by you in writing with agreed-upon costs before proceeding.
13. How Do You Handle Payment?
Understand payment expectations upfront.
Typical payment schedules:
- Deposit: 10-25% upon contract signing
- Progress payment: 25-50% when materials are delivered
- Final payment: Remaining balance upon satisfactory completion
Warning signs:
- Demanding 50% or more upfront
- Requiring full payment before work is complete
- Only accepting cash
- Pressure to pay before inspections
Safe practice: Pay with credit card or check for documentation. Never pay in full until work is complete and you’re satisfied.
14. What Safety Precautions Do You Take?
Roofing is one of the most dangerous construction jobs.
Professional roofers should:
- Use proper fall protection equipment
- Follow OSHA safety regulations
- Provide safety training for crew members
- Secure the work area to prevent accidents
- Have emergency procedures in place
- Maintain clean, organized work sites
15. Do You Offer Financing Options?
Roof replacements are expensive (typically $5,000-$25,000+).
Ask about:
- In-house financing programs
- Partnerships with financing companies
- Payment plans
- Insurance claim assistance
- Seasonal discounts or promotions

Making Your Final Decision
After interviewing multiple roofing contractors, evaluate based on:

- Experience: Years in business, similar projects completed
- Reputation: Reviews, references, BBB rating
- Communication: Responsiveness, professionalism, clarity
- Warranty: Both materials and workmanship coverage

Frequently Asked Questions
How much does a new roof cost?
A typical asphalt shingle roof replacement costs $5,000-$12,000 for an average-sized home (1,500-2,000 square feet). Costs vary based on roof size, pitch, material type, location, and complexity. Metal, tile, and slate roofs cost significantly more.
How long does a roof replacement take?
Most residential roof replacements take 1-3 days for completion. Factors affecting timeline include roof size, complexity, weather conditions, and crew size. Larger or more complex roofs may take up to a week.
How often should a roof be replaced?
Typical roof lifespans:
- Asphalt shingles: 20-30 years
- Architectural shingles: 30-50 years
- Metal roofing: 40-70 years
- Tile roofing: 50-100 years
- Slate roofing: 75-150 years
Replace when showing significant wear, multiple leaks, or approaching the end of its expected lifespan.
Should I repair or replace my roof?
Repair if:
- Damage is localized and minor
- Roof is less than 15 years old
- Only a few shingles are damaged
- Budget is tight
Replace if:
- Roof is 20+ years old
- Widespread damage
- Multiple leaks
- Significant granule loss
- Curling or missing shingles
- Sagging areas
- Extensive storm damage
Can you put a new roof over old shingles?
While some codes allow one layer of new shingles over old ones, most roofing experts recommend complete tear-off because:
- Hides underlying problems
- Adds excessive weight
- Shortens new roof lifespan
- May void manufacturer warranties
- Makes future replacement more expensive
How do I know if my roof is failing?
Warning signs:
- Missing, curled, or cracked shingles
- Granules in gutters
- Daylight through roof boards
- Sagging roof deck
- Water stains on ceilings or walls
- Increased energy bills
- Moss or algae growth
- Age (20+ years for asphalt shingles)
Do I need to be home during roof replacement?
You don’t need to be home, but someone should be available for questions. Expect noise and vibrations throughout your home. Secure valuable items, remove wall decorations, and protect fragile items in the attic.
What is the best time of year to replace a roof?
Best: Late summer to fall (dry weather, moderate temperatures)
Good: Spring (after winter damage, before summer heat)
Avoid if possible: Winter (cold temps affect shingle adhesion), peak storm season
However, roofs can be replaced year-round if necessary. If you have leaks, don’t wait for the “perfect” season.
Will my homeowner’s insurance cover roof replacement?
Insurance typically covers roof damage from:
- Storm damage (wind, hail)
- Fallen trees
- Fire
- Vandalism
Insurance usually doesn’t cover:
- Normal wear and tear
- Age-related deterioration
- Lack of maintenance
- Pre-existing damage
File claims promptly after storm damage and document everything with photos.
Bottom Line: Your roof is too important to leave to chance. Take time to research contractors, verify credentials, get multiple estimates, and ask all the right questions. A quality roofing contractor will happily answer your questions, provide documentation, and stand behind their work with solid warranties. The extra effort you put into choosing the right roofer will pay off with a quality roof that protects your home for decades.
