How to Pick a Contractor: 5-Step Checklist for Homeowners

Picking the right contractor shouldn’t feel like a gamble, but too often it does—especially after a Colorado hailstorm when “storm chasers” flood neighborhoods with door-knocks and too-good-to-be-true bids. The stakes are high: your home’s safety, your budget, your insurance claim timeline, and your sanity. One vague estimate or rushed signature can lead to delays, surprise costs, code issues, or even liens. If you’ve wondered how to separate reputable, insured pros from risky operators—and how to compare bids without getting burned—you’re in the right place.

This guide gives you a clear, repeatable process to choose with confidence. You’ll get a 5-step checklist with exactly what to do at each stage: how to build a local shortlist, verify licenses and insurance, define scope for apples-to-apples bids, lock in a rock-solid contract, and stay in control through final walk-through. Expect practical tools—key actions, smart questions, the documents to request, and Colorado-specific red flags—plus insurance-savvy tips for storm-related work. We’ll even show you how to start your shortlist with a trusted local pro, then vet every candidate the same way. Ready? Let’s build your shortlist the right way.

1. Start your shortlist with a trusted local pro: Semper Fi Restoration

The safest way to begin is to anchor your shortlist with a proven, nearby contractor who actually works your neighborhoods. Semper Fi Restoration is a veteran-owned roofing and exterior specialist based in Brighton and serving Northern Colorado and the Denver metro—built for hail, wind, and insurance-driven projects. When you’re learning how to pick a contractor, start with a dependable baseline bid from a local pro, then add two or three peers for a fair comparison.

Key actions

Create a small, high-quality pool before you invite anyone onto your roof. Keep it local, licensed, and experienced with storm-related work so you can compare apples to apples.

• Begin with Semper Fi Restoration: Veteran-owned, local roofing and exterior team serving Brighton, Thornton, Longmont, and the Greater Denver metro.


• Add 2–3 licensed locals: Ask neighbors, building inspectors, and lumberyards; cross-check with BBB profiles and recent projects.


• Schedule on-site assessments together: Same-week visits and written estimates keep timelines and scopes aligned.

Questions to ask

Early questions should confirm fit, communication, and who’s accountable for permits and inspections. Prioritize clarity over charisma.

• Do you handle insurance-claim work like mine? What’s your process with adjusters and documentation?


• Who pulls permits and is my single point of contact? How often will we get updates?


• How long have you worked with your subs, and how many jobs are active now?

Documents to request

Ask for proof before you proceed. Legitimate contractors will share these quickly and without hesitation.

• Certificate of insurance: General liability and workers’ comp, issued to you as certificate holder.


• Proof of local licensing and a street address: Not just a P.O. box.


• Three recent customer references plus one supplier reference.

Red flags and Colorado-specific tips

Hail season attracts door-knockers and “we’re in your area today” pitches. Slow down, verify, and compare against your trusted local baseline.

• Unusually low bids or pressure to “sign today,” or refusal to pull permits.


• Large upfront cash demands: Keep deposits modest (around 10%) and tie payments to milestones.


• Out-of-state storm chasers: No local insurance, references, or lien-release practices—skip them.

2. Interview and verify licenses, insurance, and references

With your local shortlist in hand, slow down and verify. Interviews plus proof protect you from liability, shoddy work, and schedule surprises—and this is where you truly learn how to pick a contractor with confidence.

Key actions

Run the same process for each candidate so your comparisons stay fair and defensible.

• Do structured phone screens: 10–15 minutes with identical questions; shortlist two or three for site visits.


• Meet on-site: Assess communication, cleanliness, and how they inspect your roof/exterior.


• Verify independently: Check license status, BBB profile, and confirm insurance directly with the carrier.

Questions to ask

Use open, factual questions that reveal experience, capacity, and accountability. Take notes and compare answers across bidders.

• Project fit: Do you take on projects of this size?


• Financial stability: Can you provide supplier or bank references?


• Team and workload: How many jobs now, and how long with your subs?


• Permits/point person: Who pulls permits and is my single contact?

Documents to request

Reputable firms send documents quickly and without pushback. File everything—insurers and inspectors may ask for copies.

• License details: Contractor’s license number and issuing jurisdiction.


• Insurance certificates: Liability and workers’ comp naming you as certificate holder; verify with insurer.


• References list: Three recent clients with addresses and phone numbers.

Red flags and Colorado-specific tips

If anything here is missing or evasive, move on. In hail season, caution beats speed—trust patterns, not promises.

• Evasion or pressure: No references/insurance, or “sign today” tactics.


• Too‑low bids/cash demands: Unusually low pricing or large upfront cash.


• Permit avoidance/out‑of‑area chasers: Won’t pull permits or lacks recent local work.

3. Define scope and get apples-to-apples bids

The secret to fair comparisons is clarity. Before anyone prices your project, write a clear scope so every bidder is estimating the same work: materials and workmanship standards, site protection, permits and inspections, timeline, warranties, and cleanup. Then require an itemized breakdown so you can spot gaps, extras, and too‑good‑to‑be‑true numbers.

Key actions

Standardize what each contractor includes so you can compare like for like.

• Write a one-page scope: Which components are in (roof, gutters, siding), known damage, and whether the job involves an insurance claim.


• Specify materials and quality: Shingle type (including impact-resistant options for hail), underlayment approach, and accessory brands/styles if you’ve chosen them.


• Require itemized pricing: Ask for materials, labor, permits/fees, and a separate line for overhead and profit; materials often run about 40% of total, with overhead/profit typically 15%–20%.


• Set schedule expectations: Target start/finish dates, daily work hours, and milestone check-ins.


• Confirm responsibilities: Who pulls permits, meets inspectors, protects landscaping, and handles debris/haul‑away.

Questions to ask

Use the same questions with every bidder to surface differences and protect your budget.

• What’s included and excluded in this price? How do you handle uncovering hidden damage and price changes?


• What warranties do I get? Spell out manufacturer and workmanship coverage in years.


• How will weather affect the schedule? What contingencies are built in?


• Who supervises daily? How many crew members and how is quality checked?

Documents to request

Insist on written, detailed paperwork you can line up side by side.

• Itemized, written estimate: With cost breakdown and assumptions noted.


• Product specs/samples: Shingles, gutters, siding, coatings, and paint systems.


• Timeline with milestones: Including inspection points.


• Permit plan in writing: Who obtains and pays for permits/inspections.


• Warranty samples: Manufacturer and workmanship terms.

Red flags and Colorado-specific tips

Storm season brings vague scopes and bargain bids. Protect yourself with detail and documentation.

• One-line lump-sum bids with no breakdown or assumptions.


• Significantly lower pricing than others; often a sign of corner-cutting or desperation.


• Refusal to include permits/inspections or to define cleanup/haul‑away.


• No impact-resistant options offered for hail-prone areas.


• Out-of-area storm chasers without recent local projects or supplier references.

4. Lock in a rock-solid contract: permits, payments, and protections

This is where good intentions become enforceable protections. A clear contract is the simplest way to control cost, quality, and schedule—and to keep your insurance claim on track. When you’re deciding how to pick a contractor, insist on a written agreement that defines scope, sets a fair payment schedule tied to milestones, requires permits, and secures lien releases.

Key actions

Put every promise in writing and tie money to measurable progress. That’s how you prevent scope creep, surprise invoices, and rushed workmanship.

• Define the full scope: Materials, brands, installation methods, site protection, debris removal, and final cleanup.


• Assign code compliance: Who pulls permits, meets the inspector, and closes them out—spelled out in the contract.


• Set a fair payment schedule: Modest deposit (around 10%), progress payments at milestones, and final 15% at completion after inspection and lien releases.


• Control changes: Written, priced, and signed change orders before extra work begins.


• Lock in warranties: Manufacturer and workmanship terms in years, plus who handles product registration.

Questions to ask

Use direct questions to confirm accountability and flush out assumptions before you sign.

• Who pulls permits and schedules inspections? What happens if an inspection fails?


• How are payments tied to milestones? Which deliverables unlock each draw?


• What’s the exact change-order process? How do changes impact schedule and price?


• What warranties do I receive, in writing? Who registers and services them?

Documents to request

Ask for templates and samples now—their paperwork is a window into their professionalism.

• Final written contract with scope, schedule, payment terms, warranties, permits, and dispute resolution (mediation/arbitration).


• Sample change-order form showing pricing, scope impact, and signatures.


• Lien release templates(conditional/unconditional) and a list of subs/suppliers.


• Permit plan(who applies/pays) and confirmation they’ll provide inspection sign-offs.

Red flags and Colorado-specific tips

Storm seasons lure shortcuts. Your contract should neutralize them before work starts.

• Large upfront cash demands or cash-only: Keep deposits modest and tie draws to milestones.


• “No permit needed” claims: Roof replacements typically require permits and inspections—don’t skip them.


• Vague, one-page proposals: No breakdowns, no change-order process, no cleanup details.


• No lien-release practice: If they can’t provide releases or name suppliers, you risk liens.


• “We’ll waive your deductible” promises: Treat offers to eat deductibles or inflate claims as red flags—protect your policy and stay compliant.

5. Stay in control during the build and closeout

Once work starts, your leverage is cadence and documentation. Hold the team to the agreed scope, approve changes only in writing, and tie each payment to visible milestones. Weather happens—especially in Colorado—but tarping, communication, and inspection sign‑offs keep quality on track. Close out only after punch‑list items are complete and lien releases are in hand.

Key actions

• Set a cadence: Weekly check‑ins with your point of contact; same‑day updates for weather delays or discoveries.


• Walk the site: Verify materials match the contract; confirm site protection, magnet nail sweeps, and daily cleanup.


• Approve changes in writing: No work proceeds without a signed, priced change order.


• Track milestones: Release payments only after milestone deliverables (e.g., dry‑in, inspection pass) are met.


• Punch list and closeout: Create a written punch list; confirm warranty registration and final inspection approval.

Questions to ask

• What’s the plan for weather this week, and how will the roof be protected overnight?


• Which milestone are we completing before the next draw? What proof will I see?


• What’s still open on the punch list and when will it be finished?

Documents to request

• Daily/weekly progress notes and photos tied to milestones.


• Signed change orders with costs and schedule impact.


• Permit and inspection approvals(rough/final).


• Conditional progress lien waivers from GC, subs, and suppliers; unconditional final lien waivers before the last payment.


• Final invoice marked “paid in full” and written workmanship/manufacturer warranties.

Red flags and Colorado-specific tips

• No posted permit or skipped inspections; insist on documentation.


• Vague “material substitutions” due to “shortages” without a signed change order.


• Inadequate weather protection(no tarps/dry‑in) during hail or afternoon storms.


• No magnet sweep or debris control; nails in driveways and gutters are unacceptable.


• Pressure to release final payment before punch‑list completion, lien waivers, and final inspection sign‑off.

Next steps

You’ve got a straightforward, five-step path to hiring right: start local, verify, define a tight scope, sign a protective contract, then manage the build through closeout. Follow it and you’ll sidestep storm-season pressure, compare bids on equal footing, protect your budget with milestones and change orders, and finish with permits closed, warranties in hand, and peace of mind.
