How to Vet a Roofing Contractor in Colorado: 5 Questions to Ask
Choosing a roofing contractor is one of the more consequential home improvement decisions you'll make. A roof failure is expensive to fix, difficult to live with, and sometimes not covered by insurance if the installation work was substandard. In Colorado, where hail seasons are active and storm chasers flood neighborhoods after every major event, it's worth taking a few extra steps before you sign anything.
These five questions won't take long to ask and the answers will tell you a lot.
1. Are You Licensed and Insured in Colorado?
Colorado does not require a state-level roofing license, but many municipalities and counties have their own requirements. More importantly, any contractor working on your home should carry both general liability insurance and workers' compensation coverage. If a worker is injured on your property and the contractor doesn't carry workers' comp, you could be held liable.
Ask for certificates of insurance, not just verbal confirmation. A legitimate contractor will have no hesitation providing them. You can also call the insurance carrier directly to verify the policy is current.
2. Are You a Local Company?
After a significant hail storm, out-of-state contractors move through Colorado neighborhoods quickly. Some do fine work. Others disappear the moment a problem surfaces. A company with a permanent local presence has more at stake. They have a reputation to protect, a physical address you can show up to, and they'll be around if something goes wrong after the job is done.
Ask where the company is based, how long they've operated in the area, and whether they have local references you can contact. The National Roofing Contractors Association recommends verifying that any contractor you hire has a verifiable local business address before work begins.
3. What Does Your Warranty Cover, and Who Backs It?
There are two distinct warranties involved in any roofing project: the manufacturer's warranty on the materials, and the contractor's workmanship warranty on the installation. Both matter.
A manufacturer's warranty covers defects in the shingles or roofing materials themselves. A workmanship warranty covers how the job was done. Many roofing failures aren't material defects. They're installation errors, and a materials-only warranty won't cover those.
Ask specifically: How long is the workmanship warranty? Is it transferable if you sell the home? Who do you call if something goes wrong. The contractor or the manufacturer? Get the answers in writing.
4. Will You Pull a Permit?
In most Colorado jurisdictions, a full roof replacement requires a permit. Pulling one triggers an inspection, which means a third party confirms the work meets local building code. Some contractors skip this step to move faster or keep costs down. That's a red flag.
If work is done without a required permit and you later sell the home, you may be required to disclose it. It can also complicate insurance claims. A contractor who pushes back on permits or suggests you don't need one is worth walking away from.
5. Can I See References From Similar Projects in This Area?
Any contractor can say they do good work. References let you verify it. Ask for homeowners they've worked with in the past year or two, in a similar area and ideally with a similar scope of work.
When you follow up, ask the reference a few specific questions: Did the crew show up when scheduled? How did the contractor handle problems that came up during the job? Would you hire them again? Those answers are more useful than a generic five-star rating.
A Note on Storm Chasers
Colorado's hail season draws contractors from across the country who target neighborhoods after major storms. Some are experienced and legitimate. Many are not. The warning signs: pressure to sign immediately, large upfront payments requested in cash, no local address, and claims that they'll "handle everything" with your insurance company. A good contractor will help you understand your claim and document damage thoroughly. But the relationship with your insurer is yours to manage.
Taking an extra day to ask these questions before you hire is worth it. A roof replacement is a significant investment, and the contractor you choose will determine whether that investment holds up.
Frequently Asked Questions
Does Colorado require roofing contractors to be licensed?
Colorado does not have a statewide roofing license requirement, but some cities and counties do. Denver, for example, has local licensing requirements for contractors. Always check your specific municipality's requirements, and regardless of licensing, confirm that any contractor carries current liability insurance and workers' compensation coverage.
How do I know if a roofing contractor is trying to scam me?
Common warning signs include high-pressure tactics to sign a contract quickly, requests for large cash payments upfront, no verifiable local address or phone number, and reluctance to pull permits or provide proof of insurance. Legitimate contractors will answer your questions directly, provide documentation without hesitation, and not pressure you to decide immediately.
What's the difference between a manufacturer's warranty and a workmanship warranty?
A manufacturer's warranty covers defects in the roofing materials themselves, such as shingles that crack or fail prematurely. A workmanship warranty covers errors made during installation. The two are separate, and both are important. Ask your contractor to explain both in detail before signing a contract.
Should I get multiple quotes before hiring a roofing contractor?
Yes. Getting two or three quotes gives you a basis for comparison. Not just on price, but on what each contractor is proposing to do. If one bid is significantly lower than the others, ask why. Sometimes it reflects a less experienced crew, lower-quality materials, or work that doesn't include everything the other bids cover.
How do I know if my roof actually needs to be replaced or just repaired?
Not every storm or every leak means you need a full replacement. A qualified contractor should be able to walk you through what they found during an inspection and why they're recommending what they are. If you're unsure, it's reasonable to get a second opinion.
