A Complete Guide to Picking the Right Roofing Contractor

A roofing contractor is not just another option for upgrading your home — they are an investment in long-term protection. Your roof is the first line of defense against weather damage such as rain, sun, wind, humidity, snow (in colder areas), and the wear and tear of the structure itself. A poor contractor can create leaks, mold, rotting decking, damaged insulation, and costly repairs that may not show up until months later.

The good news is that you can avoid most roofing mistakes by following a simple but thorough hiring process.

This guide will help you hire with confidence by explaining exactly how to choose the best roofing contractor — what to look for, what to ask, and what to avoid.


Why It’s Important to Choose the Right Roofing Contractor

Even the best roofing materials — metal, shingles, tile, or membranes — can fail if they are not installed correctly. Roofing works as a complete system. Underlayment, ventilation, flashing, fasteners, drip edges, valleys, and drainage must all work together.

A professional contractor ensures:

  • Properly sealing valleys, edges, and penetrations like chimneys and vents
  • Correct installation methods according to manufacturer guidelines
  • Proper ventilation to prevent moisture and heat damage
  • Clean workmanship to reduce future leak risks
  • Compliance with building codes and safety standards
  • Warranty protection for both materials and labor

A roof is truly "done" when it is engineered to withstand harsh weather for years — not just when it looks good.


Many homeowners skip this step because the contractor seems professional. Never rely on appearance — always verify.

✅ Licensing (if required)

A licensed contractor is typically required to meet professional standards. Licensing protects you from:

  • Unqualified workers
  • Unregistered companies
  • Unsafe or non-code work

Always request the license number and official business name.

✅ Liability Insurance

This protects you if the contractor damages:

  • Walls, windows, driveway
  • Landscaping
  • Neighbor’s property
  • Water or electrical lines

Without liability insurance, you may be responsible for damage costs.

✅ Workers’ Compensation

Roofing is dangerous work. If a worker gets injured on your property and the contractor does not carry workers' compensation insurance, you could face legal and medical liability.

Pro Tip: Ask for official proof documents, not just verbal confirmation.


2) Choose Experience Based on Roof Type

Roofing requires specialized skills. A contractor experienced in shingle roofing may not be ideal for flat membrane systems. Tile and slate require special handling.

Ask These Questions:

  • How long have you been installing this type of roof?
  • How many similar projects have you completed recently?
  • Do you have photos of similar work?

Why Specialization Matters

An experienced contractor understands:

  • Proper flashing methods
  • Correct slope requirements
  • Material expansion behavior (important for metal roofs)
  • Drainage planning for flat roofs
  • Local weather challenges

This significantly reduces future failure risks.


3) Review Local Reputation (Not Just Star Ratings)

Online reviews are helpful, but patterns matter more than star ratings.

Look for Consistent Mentions Of:

  • Completing projects on time
  • Maintaining a clean job site
  • Honoring warranties
  • Clear communication
  • Transparent billing

Red Flags Include:

  • “Stopped responding after payment”
  • “Did not show up as scheduled”
  • “Leak returned and they refused to fix it”
  • “Hidden charges added later”

A strong local reputation also means easier access for future warranty or maintenance needs.


4) Request Verified References

A trustworthy contractor should provide 2–5 references.

When speaking with references, ask:

  • Did the roof leak after installation?
  • Was the crew organized and respectful?
  • Was the project completed on time?
  • Did the final cost match the estimate?
  • How were unexpected issues handled?
  • Would you hire them again?

Hesitation or vague answers can reveal concerns.


5) Get Three Detailed Written Estimates

Never hire based on a single quote. Obtain at least three written estimates to compare:

  • Market pricing
  • Scope of work
  • Included and excluded items

A Professional Estimate Should Include:

  • Roofing material brand and type
  • Underlayment type
  • Flashing replacement details
  • Ventilation improvements (if needed)
  • Labor cost
  • Tear-off and disposal plan
  • Project timeline
  • Payment schedule
  • Warranty details
  • Cleanup plan (debris removal, nail magnet use)

Why This Matters

Lower quotes sometimes exclude:

  • Quality underlayment
  • New flashing
  • Replacement of damaged decking
  • Proper fasteners
  • Ventilation upgrades

A roof may look perfect on day one but fail within the first year if corners are cut.


6) Understand Roofing Warranties

There are two main warranty types:

1) Manufacturer Warranty (Materials)

Covers defects in roofing materials like shingles, membranes, and metal panels. Many require proper installation methods for validity.

2) Workmanship Warranty

Covers installation errors and is provided by the contractor.

Ask:

  • How long is the workmanship warranty?
  • What does it include?
  • Is it written and signed?
  • Is it transferable to future buyers?

A reputable contractor stands behind their workmanship.


7) Avoid Storm Chasers and High-Pressure Sales

After storms, temporary contractors often offer quick deals like:

  • “Today-only pricing”
  • “Insurance tricks”
  • “Pay now, start tomorrow”

Risks Include:

  • No long-term warranty support
  • No stable office presence
  • Reduced accountability
  • Rushed workmanship

Choose established local contractors instead.


8) Evaluate Communication and Professionalism

Professional behavior during the quoting stage reflects future performance.

Signs of Professionalism:

  • Clear and respectful communication
  • Detailed written scope
  • Honest expectations
  • Consistent responses

Roofing projects require coordination. Poor communication often leads to mistakes and delays.


9) Review the Contract Carefully

Never begin work without a detailed written contract.

It Should Include:

  • Full scope of work
  • Materials list
  • Payment schedule
  • Change order policy
  • Timeline
  • Warranty terms
  • Cleanup responsibilities
  • Procedures for discovering rotten decking
  • Permit responsibility

Any verbal promise must be written into the contract.


10) Payment Terms: Avoid Full Upfront Payments

A reputable contractor typically requests:

  • A reasonable deposit
  • Progress payment after materials are delivered
  • Final payment after completion and inspection

Red Flags:

  • Demanding full payment upfront
  • Refusing written receipts
  • Cash-only pressure without documentation

Fair payment terms protect both parties.


11) Must-Ask Questions Before Hiring

  1. Are you licensed and insured?
  2. Who supervises the project daily?
  3. What materials will you use (brand and type)?
  4. Will you replace flashing or reuse old materials?
  5. How will ventilation and insulation be handled?
  6. What does cleanup include?
  7. How do you protect landscaping?
  8. What happens if rotten decking is found?
  9. What warranties do you offer?
  10. Can you provide recent references?

Confident and transparent answers indicate professionalism.


Warning Signs: When to Walk Away

Avoid contractors who:

  • Refuse to provide insurance proof
  • Avoid written estimates
  • Pressure immediate signing
  • Offer unrealistically low pricing
  • Lack a physical address
  • Avoid discussing flashing or ventilation
  • Cannot clearly explain warranties

Cheap roofing often becomes expensive roofing later.
