Key Takeaways

• Verify license, insurance, and workers’ comp first—before talking price or materials.
• Choose a contractor you can still call years from now; local accountability and a real address matter.
• Compare quotes by scope, not just price—make sure flashing, ventilation, decking policy, cleanup, and warranties are all clear.
• A professional estimate is line‑itemed, photo‑documented, and backed by written warranties—not pressure tactics.
• If a contractor won’t explain, document, or answer questions clearly, walk away.

 

You Deserve a Contractor You Can Call Years From Now

Most homeowners only replace a roof once or twice in their lives, which makes picking the right contractor feel high‑stakes.

The good news: you don’t need to become a roofing expert to protect yourself—you just need a clear, simple vetting checklist and 15–30 minutes to use it.

You deserve clear answers, not pressure.

Quick Answer: The 5 Must‑Check Items

Before you worry about shingle brands or colors, confirm these five things:

1. License – Active, in good standing, and correctly classified for roofing work in Oregon.
2. Insurance certificate – General liability and workers’ comp, verified via an official Certificate of Insurance (COI).
3. Local address + longevity – A real physical location and a local history that shows they’ll still be here tomorrow.
4. Written scope – A line‑item estimate that spells out materials, flashing, ventilation, decking policy, and cleanup.
5. Warranty clarity – Written explanation of both manufacturer and workmanship warranties, and what can void them.

If a contractor passes those five checks, you’re starting from a much safer place.

The Full Vetting Checklist (Step‑by‑Step)

Break your vetting into four quick stages. You can do most of this from your kitchen table.

Stage A — Identity & Legitimacy

Goal: Confirm they are who they say they are—and that Oregon actually recognizes them.

• Business name matches license and insurance
  In Oregon, anyone paid to repair or improve a home (including roofers) must be licensed with the Construction Contractors Board (CCB).
  • Ask for their CCB license number.
  • Look it up using the state’s online search or tools like OR CCB.
  • Make sure the company name and status match.
• Local physical address (not just a PO box)
  Search the address in Google Maps and on their website; you’re looking for a real, consistent business location.
• Years in business locally
  Check their license history and complaint record, which in Oregon can go back up to 10 years.
• Reviews across platforms
  Look for consistent patterns in Google, Yelp, BBB, or other platforms—recurring themes matter more than one‑off perfect or angry reviews.

Stage B — Safety & Liability

Goal: Make sure you’re protected if someone gets hurt or something gets damaged.

• Certificate of Insurance (COI)
  A roofer “saying” they’re insured is not enough. Ask their agent to email you a Certificate of Insurance that shows:
  • General liability coverage (protects your property)
  • Workers’ compensation coverage (protects you if a worker is injured on your property)
• Without workers’ comp, an injured worker may have the legal right to sue the homeowner.
• Workers’ comp listed on the COI
  Confirm it’s active and issued to the same company name that’s on your estimate and contract.
• Safety procedures
  Ask how they handle fall protection, debris control, and protecting landscaping, siding, and windows.

Stage C — Scope & Quality

Goal: Make sure the quote covers a complete, long‑lasting roof—not just the bare minimum.

A professional estimate usually includes these items in writing:

• Detailed materials list
  • Shingle/roofing brand and product line
  • Underlayment type (synthetic vs. felt; ice/water shield areas)
  • Ridge caps, starter strips, fasteners
• Flashing plan
  Very few leaks start in the middle of a shingle field—they start at chimneys, walls, skylights, and vents.
  Your estimate should clearly say which flashings are being replaced and how.
• Ventilation check
  Healthy roofs need balanced intake and exhaust ventilation; in Oregon’s climate, this affects both performance and warranty validity.
  Look for notes about attic inspection, soffit/ridge vents, or other exhaust options.
• Decking policy
  There should be a clear plan for replacing rotten or damaged wood, usually as:
  • A per‑sheet price, and/or
  • An allowance, plus a written change‑order process
• Cleanup plan
  Including dumpster/haul‑off and magnet nail sweep expectations, multiple passes are common for safety.

Stage D — Trust & Communication

Goal: Choose someone you can communicate with comfortably before, during, and after the job.

• References you can call
  Ask for 2–3 recent local homeowners. Call and ask what went well, what could’ve been better, and whether they’d hire the contractor again.
• Timeline expectations & weather policy
  You should know the expected start window, approximate duration, and how weather delays are handled.
• Communication plan
  Ask who your main contact will be, how you’ll get updates, and how issues are handled during the job.
• Payment terms
  Look for a reasonable deposit (not most of the job up front), with the balance due at clearly defined milestones or at substantial completion.

Verification Checklist: What to Check, How, and What “Good” Looks Like

Information Table #1: Verification Checklist

What to Verify	How to Verify	What “Good” Looks Like
License	Use Oregon CCB’s online search or a tool like OR CCB; enter the license #.	License is active, matches the company name, correct classification, and no serious unresolved complaints.
Insurance (General Liability)	Request a Certificate of Insurance from the contractor’s agent.	Current policy with appropriate limits, issued to the contractor named on your quote.
Workers’ Comp	Confirm workers’ comp coverage is listed on the COI.	Active workers’ comp policy; protects you from injury claims if someone is hurt on your property.
Local Address	Check the address on Google Maps, website, and paperwork.	Real business location (office/shop), not only a PO box; consistent across documents.
References	Call 2–3 recent clients provided by the contractor.	Homeowners confirm good communication, cleanup, and that the contractor returned if minor issues came up.
Written Scope	Review the line‑item estimate.	Clear description of materials, flashing, ventilation, decking policy, cleanup, and warranties; not a single line “replace roof.”
Warranty	Ask for written workmanship and material warranty terms.	Durations clearly stated (e.g., X‑year workmanship, Y‑year manufacturer), plus conditions to keep coverage valid.
Change‑Orders	Ask how hidden damage will be handled and documented.	Written policy: photos + explanation + written approval before extra costs are added.

Questions to Ask (And How to Interpret the Answers)

Information Table #2: Questions, Good Answers, and Red Flags

Question to Ask	A Good Answer Sounds Like…	A Red‑Flag Answer Sounds Like…
“Can you show photos of what you found on my roof?”	“Yes—here are the photos and what we’re seeing in each area.”	“You’ll just have to trust us; we do this all the time.”
“What’s included in your flashing work?”	“We’re replacing flashing at chimneys, walls, valleys, and pipe boots; here’s our written scope.”	“Standard flashing” or “We’ll caulk what needs it.”
“How do you handle rotten or soft decking?”	“We include an allowance and a per‑sheet price; if we find more, we’ll show you photos and get your written approval first.”	“We’ll figure it out later” or no clear per‑sheet cost.
“What’s your cleanup process?”	“Daily cleanup, plus a full magnet nail sweep around the house and driveway when we’re done.”	“We clean up” (no details).
“What warranties apply to my job?”	“You’ll have a manufacturer’s warranty on the materials and an X‑year workmanship warranty from us; here are both in writing.”	“Lifetime warranty” with no written terms or distinction between material and labor.
“Do you check and address attic ventilation?”	“Yes. We look at intake and exhaust and recommend changes if needed, especially in older homes.”	“Not needed” or “We just put on what you had before.”
“How do your payments work?”	“We take a reasonable deposit, then the balance after completion or at clear milestones. It’s all in your contract.”	“We need a large cash deposit up front” or vague answers about timing.

How to Compare Quotes Apples‑to‑Apples (Quick Method)

Once you’ve vetted contractors, compare their quotes this way:

1. Confirm you’re looking at the same roof areas.
   Make sure each quote covers the same structures (house, garage, additions, porches).
2. Normalize the basics:
   • All are full tear‑off (or all overlays), with layers removed clearly stated
   • Underlayment types are comparable (e.g., all synthetic)
   • Similar flashing scope (chimneys, walls, skylights, valleys)
   • All include new vent boots, not just resealing
   • Decking allowance or per‑sheet pricing is clear in each
   • Ventilation is at least evaluated; any upgrades are noted
   • Cleanup and magnet sweep are included
   • Warranty durations are comparable
3. Only then compare total price.
   If one quote is much lower but includes less scope, it’s not cheaper—it’s just a smaller job on paper.

Common Red Flags & Pressure Tactics

You don’t have to memorize every scam—just recognize the patterns.

• Door‑to‑door pressure right after storms
  Especially when combined with “free roof” or “insurance will pay for everything” claims.
• “Sign today” discounts or expiring offers
  Legitimate contractors don’t need you to decide on the spot.
• Refusal to show license or COI
  Or documents that don’t match the company name on your estimate.
• Vague, one‑line scopes
  “Replace roof: $XX,XXX” with no detail on materials, flashing, decking, or ventilation.
• Caulk‑heavy “fixes” pitched as permanent solutions
  Sealant has its place, but it’s not a substitute for proper flashing or material replacement.
• Cash‑only, large deposits up front
  Especially if combined with no written contract and no clear schedule.

If at any point you feel rushed, confused, or talked in circles, that’s a sign to step back.

FAQs: Vetting a Roofing Contractor

How many roofing quotes should I get?

Most experts recommend 2–3 quotes from vetted, licensed, and insured contractors. More than that can create noise without adding clarity—quality of information matters more than quantity.

How do I verify a roofer’s license and insurance in Oregon?

• Use the Oregon CCB online search (or OR CCB) to check license status, business name, and complaint history.
• Ask their insurance agent to send you a Certificate of Insurance showing general liability and workers’ comp coverage.

What’s a reasonable deposit for roofing work?

It varies, but many reputable contractors take a modest deposit with the balance due at completion or in staged payments—not most of the job up front. Be cautious of very large upfront cash demands.

Why are quotes so different?

Because contractors make different assumptions about scope—tear‑off layers, decking repairs, flashing replacement, material grade, ventilation, and cleanup. Normalize those items, and many price gaps make more sense.

What should a written roofing estimate include?

At minimum: roof size, tear‑off, materials (brand/line), underlayment, flashing, vent boots, ventilation plan, decking allowance, permits (if any), cleanup, payment schedule, and warranties.

Do I need to replace flashing during replacement?

In most full replacements, yes—especially at chimneys, walls, valleys, skylights, and pipes—unless specific pieces are very new and clearly sound. Re‑using old flashing is a common cause of post‑replacement leaks.

What’s the difference between manufacturer and workmanship warranties?

• Manufacturer warranty – Covers defects in the roofing materials themselves.
• Workmanship warranty – Covers installation errors and labor; this is who you call if something leaks because of how it was installed.

You need both explained in writing.

How do I avoid storm chasers after bad weather?

• Don’t sign anything at the door.
• Verify license, COI, and local address before you even consider a bid.
• Get a local, photo‑documented inspection and compare scopes before filing a claim or choosing a contractor.
