A roof is one of the few home projects you cannot easily watch. The work happens overhead, most of it is covered by the end of the first day, and the mistakes show up years later. That makes choosing the roofer the single most important decision in the project.
Licensing in Colorado Works Locally
Colorado does not issue a statewide roofing contractor license. Instead, many towns, cities and counties require contractors to register or hold a local license before they can pull permits. A roofer who works in Parker, Castle Rock and Highlands Ranch may carry several local registrations. Ask the building department for your address what it requires, and ask the roofer to show theirs.
Five Vetting Steps, In Order
- 01
Confirm a real local presence
A physical address you can drive past, a local phone number and a history in the area. Storm chasers often have none of these.
- 02
Verify insurance directly
Liability and workers' compensation, confirmed with the carrier. If a worker is hurt on your roof, this is what protects you.
- 03
Check local registration
Ask the town or county whether the company is registered to pull permits there.
- 04
Ask for local references
Recent jobs in your area, ideally a few years old, so you can see how the work has held up through a winter or two.
- 05
Compare written scopes
Only then compare prices, with scopes lined up side by side.

Reading a Proposal Line by Line
Two proposals for "a new roof" can describe very different jobs. Put them side by side and look for these lines. Anything missing is a question, not an assumption.
| Line item | What a clear proposal says | Vague version to question |
|---|---|---|
| Shingle | Manufacturer, product line, color | "Architectural shingle" |
| Tear-off | Remove all layers to the deck | Not mentioned |
| Decking | Replacement priced per sheet, with photos | "As needed" |
| Ice barrier | Where it goes and how far up | Missing |
| Flashing | New step, counter and pipe flashing | "Reseal as needed" |
| Ventilation | Intake and exhaust type, quantity | "Vents" |
| Permit | Who pulls it, included in price | Not listed |
Red Flags Worth Walking Away From
The messy middle: the referral that skipped the paperwork
A common regret is not a scam at all. It is a friendly neighbor's roofer, hired on a handshake, with no written scope. Then the deck turns out to need work, the price grows, and there is nothing to point to. Even with someone you trust, get the proposal in writing. It protects the relationship as much as the roof.
Two Warranties, Two Different Promises
Roofing warranties confuse almost everyone because there are usually two of them. The manufacturer's warranty covers defects in the shingles or panels themselves. Its length and what it pays for depend on the product line and, often, on whether the installer registers the job or holds a certification with that manufacturer. The workmanship warranty comes from the roofer and covers installation mistakes, such as a flashing detail that leaks. It is only as good as the company's willingness and ability to come back.
Ask for both in writing, with the length and what is excluded. Ask whether the manufacturer warranty is transferable if you sell the house. And ask what the roofer does when a leak call comes in during the first winter: who you call, and how quickly someone looks. A clear answer is a good sign; a vague one tells you something too.
During and After the Job
On install day, ask for photos of the deck after tear-off and of the underlayment and flashing before shingles cover them. After the job, collect the final invoice, the permit sign-off, lien waivers and warranty registration in one folder, along with any HOA approval. If the work is tied to a claim, the insurer usually needs that final invoice to release held-back depreciation; the hail claims guide covers that step, and the permits and contracts guide covers your rights under Colorado law.
Questions Parker Homeowners Ask
Does Colorado license roofers?
Colorado does not have a statewide roofing contractor license. Licensing or registration is handled locally, by towns, cities and counties, and requirements differ. Ask the building department for your address what applies, and ask the roofer to show it.
How many bids should I get?
Two or three written bids with comparable scopes is usually enough to see what is normal and what is missing. More than that tends to add confusion, not information.
Is the cheapest bid a bad sign?
Not automatically. A low bid is a reason to compare the scope line by line. Missing flashing, reused vents or no permit line explain most low numbers.
Should I pay a deposit?
Payment terms vary. A modest payment tied to material delivery is common; a large sum before any materials arrive is a reason for caution. Tie payments to milestones and get receipts.
