How to Choose a Commercial Roofing Contractor in Colorado and Nebraska

Short answer: neither Colorado nor Nebraska issues a statewide roofing license, so check licensing in the jurisdiction your building is in. Verify insurance with the insurer, not the contractor. Confirm they are certified by the manufacturer of the system going on your roof, because that is what makes the manufacturer warranty available. Get both warranties in writing, and make every bidder price the same scope.

Choosing a commercial roofer is a harder problem than choosing most trades, for a structural reason: you cannot inspect the finished work. The roof is out of sight, most of what determines its service life is buried under the membrane, and the difference between a good installation and a poor one may not surface for three or four years. By then the crew is gone and the question is whether anyone is left to call.

So the evaluation has to happen before the work, using checks that are actually verifiable. Here is what those are.

Licensing is local in both states, so ask locally

Colorado sets no statewide roofing code and issues no statewide roofing contractor license. Requirements are set jurisdiction by jurisdiction, so what a contractor must hold in one city is not what they must hold in the next. This is the single most misunderstood point in the whole process, because it makes "are you licensed?" an almost meaningless question on its own. Rifle, for instance, runs its own contractor licensing scheme where a neighboring jurisdiction may not.

Nebraska works the same way at the competency level, with one extra step at the state level. There is no statewide roofing licence, but contractors must register with the Nebraska Department of Labor under Neb. Rev. Stat. 48-2101 to 48-2117. That registration is a filing requirement, not a skills test, so it tells you a contractor exists on the state's books and nothing about whether they can build your roof. Anything beyond it is set by the city or county, and the local rules genuinely differ across the Panhandle: some jurisdictions register contractors themselves, and neighbouring towns administered by the same building department do not always carry the same requirement. Confirm the specific rule with the building department for the address, or ask our Scottsbluff office, which pulls those permits routinely.

The useful version is specific: are you licensed to pull a permit for this class of work in this jurisdiction, and will you be pulling the permit? A contractor who wants the owner to pull the permit is asking you to carry the code responsibility for their work, and that alone should end the conversation.

Verify insurance with the insurer

Two policies matter: general liability and workers' compensation. Liability covers damage to your building and its contents. Workers' compensation covers injury to the crew, and its absence is the one that can reach you, because an uninsured injury on your roof is a problem that goes looking for whoever has assets.

Ask for the certificate of insurance to come directly from the insurer or the agent, not as a document forwarded by the contractor, and check two things: that the limits are appropriate to the size of the project, and that the coverage period actually spans the work rather than lapsing halfway through.

Manufacturer certification decides your warranty

This is the check most owners skip, and it has the largest consequence. Manufacturers of commercial roof systems generally only extend their system warranties through contractors they have approved and trained to install their products. If the contractor is not certified for the system going onto your roof, the strongest warranty available for that roof is usually not available to you, no matter what the contract says about workmanship.

Ask which manufacturers they hold current certification with, and check that it covers the specific system being proposed rather than a different product from the same maker. You can see the certifications CRC holds on our certifications page.

Get both warranties in writing

Commercial projects should carry two, and they do different jobs:

• The manufacturer warranty covers the roof system to the manufacturer's terms. Read what it actually covers: material only, or material and labor, and what maintenance it requires of you to stay valid.
• The workmanship warranty is the contractor standing behind the installation. Its value depends entirely on the contractor still existing when you need it, which is why local track record is not sentiment, it is risk assessment.

Both should be handed over as documents. A warranty that is described in a sales conversation and never appears on paper is not a warranty.

Make the bids comparable

Three bids are only useful if they are pricing the same job. In practice they often are not: one includes a full tear-off and another proposes a recover, one specifies thicker insulation than the next, one carries a longer manufacturer warranty, one includes the rooftop equipment work and another leaves it out. Compared on price alone, the cheapest number simply describes the smallest scope.

Define the scope yourself, or have one contractor define it and ask the others to price against that definition. Then compare like for like on:

1. System and specification. Which membrane or assembly, what thickness, what insulation and how much of it.
2. Tear-off or recover. Whether the existing roof is coming off, and what happens if wet insulation is found once it does.
3. The unknowns. Deck repair is the classic one. How is it priced if the deck under the old roof turns out to be deteriorated?
4. Warranty term and type. Length is not the whole story; coverage is.
5. Schedule and site conduct. Working hours, tenant access, protection of the building and its contents, and daily cleanup.

After a hail storm, the rules change

A major hail event brings out-of-area crews into Colorado and the Nebraska Panhandle within days, and the pattern is recognizable in both. Out-of-state plates. A door knock or a call very soon after the storm. Pressure to sign something immediately, often framed as securing a place in a queue. No permanent local address, and no answer to what happens if there is a problem in year three.

The clearest signal is an offer to cover, absorb, or waive your insurance deductible. In Colorado, C.R.S. 6-22-105 makes it illegal for a roofing contractor to pay, waive or rebate any part of your deductible, or to advertise that they will. A contractor offering it is proposing to break the law to win your job, which tells you what their other assurances are worth, and it can put your claim at risk: an insurer is not obligated to honor the estimate of a contractor who has violated it.

Nebraska has its own version of that rule, and its scope is worth knowing precisely rather than assuming. Neb. Rev. Stat. 44-8604 says a residential contractor shall not promise to rebate any portion of an insurance deductible as an inducement to a sale. It sits inside the Insured Homeowners Protection Act, which defines the property it covers as residential, so a commercial building owner in the Panhandle should not assume the statute protects them the way it protects a homeowner. Nor does the Colorado statute reach across the state line. What travels is the judgement: a contractor who opens by offering to make your deductible disappear is telling you how they intend to handle everything else. Confirm any specific legal question with the building department for your address or your own counsel.

The defense is unglamorous: deal with contractors who have a physical local address and a history you can check, and do not sign anything at the door. That test should be applied to us as readily as to anyone knocking: CRC's offices are staffed addresses you can visit in Denver, Grand Junction and Scottsbluff. If you are working through a storm claim, our guide on what to expect from a roof insurance adjuster covers how the process should run.

Questions worth asking out loud

• Are you licensed and permitted in this jurisdiction, and will you pull the permit?
• Can your insurer send the certificate of insurance directly?
• Which manufacturers are you certified with, for this system?
• Who is actually on my roof, your employees or a subcontracted crew?
• Who is my point of contact once work starts, and what happens if it rains?
• How is deck repair priced if you find deteriorated deck under the old roof?
• Can I see a commercial roof you completed near here, three or more years ago?

That last one is the most revealing question on the list. A new roof looks good in any photograph. A roof that has been through three Front Range, Western Slope or Panhandle hail seasons is evidence. You can see CRC's completed work on our projects page, and the full range of commercial roofing services we provide from our Denver, Grand Junction and Scottsbluff offices, each of which lists its address, hours and the towns it covers.

Frequently Asked Questions

Do Colorado and Nebraska license roofing contractors?

Neither state issues a statewide roofing contractor license. Colorado handles licensing and permitting locally, so requirements differ between municipalities and counties. Nebraska requires contractors to register with the state Department of Labor under Neb. Rev. Stat. 48-2101 to 48-2117, and any competency licensing above that is set by the city or county. In both states the useful question is not whether a contractor is licensed in general, but whether they are licensed, registered and permitted to work in the jurisdiction your building sits in.

What insurance should a commercial roofing contractor carry?

General liability and workers' compensation at minimum, with limits appropriate to the size of your building and project. Ask for a certificate of insurance sent directly from the insurer or agent rather than a copy from the contractor, and check that the coverage dates span your project rather than expiring partway through it.

Why does manufacturer certification matter on a commercial roof?

Manufacturer warranties on commercial membrane are generally only available through contractors the manufacturer has approved to install their systems. If the contractor is not certified for the system going on your roof, the strongest warranty available to you usually is not, regardless of what the workmanship warranty says.

What is the difference between a workmanship warranty and a manufacturer warranty?

A workmanship warranty is the contractor's promise to stand behind the installation, and it is only as good as the contractor still being in business. A manufacturer warranty comes from the material maker and covers the system to its terms. Commercial projects generally want both, and they should be given to you in writing rather than described.

How do I spot a storm chaser after a hail event?

The pattern is out-of-area plates, a door knock within days of the storm, urgency about signing immediately, an offer to cover or absorb your deductible, and no permanent local address. In Colorado, C.R.S. 6-22-105 makes it illegal for a contractor to pay, waive or rebate any part of your deductible. Nebraska has its own rule in Neb. Rev. Stat. 44-8604, though that one is written for residential property, so a commercial owner in the Panhandle should treat the offer as a character signal rather than assume the same statute covers them. Either way it tells you what the rest of their assurances are worth.

How many bids should I get for a commercial roof?

Enough to compare, usually three, but only if you can compare them like for like. Bids specifying different systems, different insulation thicknesses, or different amounts of tear-off are not comparable on price. Ask every bidder to price the same defined scope, or the cheapest number will simply be the smallest scope.
