Roofing Contractor Northglenn CO
That One Construction Co. works with homeowners in Northglenn, CO who need a roofing contractor with real experience handling insurance claims, navigating a drive-by inspection process that most contractors in this market do not know going in, and replacing roofs on the 1970s ranch homes and split-levels that make up the core of the city. We handle the full process from the initial inspection through the final walk, for homeowners dealing with storm damage or a roof that has reached the end of its run.
The May 2024 Storm Hit Northglenn After Midnight and Left Homeowners Unaware Until Morning
On the night of May 30, 2024, a severe thunderstorm tracked southeast from Erie through the northern Denver metro. 9News named Northglenn explicitly as one of the cities directly in the storm’s path. The Denver Gazette confirmed hail larger than an inch in Northglenn specifically. The National Weather Service recorded 20 separate reports of hail exceeding 1.5 inches along the corridor, with golf ball-sized hail confirmed across the northern metro. The storm hit after midnight.
That timing matters. A hailstorm that arrives at 1 AM leaves homeowners with no way to know what happened to their roof until they walk outside the next morning, and even then, most of the damage is not visible from the ground. Granule loss, bruised shingles, cracked pipe jacks, and bent flashing only show at roof level. The May 2024 event became Colorado’s second-costliest hailstorm on record at $1.9 billion in insured losses. Many Northglenn homeowners still have not had their roofs inspected. If that storm tracked over your neighborhood and you have not had a professional look at the roof since, call us.
The 2024 event was not the first to hit Adams County hard. The June 2018 storm produced $2.8 billion in statewide insured losses and tracked through the county corridor. A 2017 event producing $2.3 billion moved northeast from the foothills through Adams County toward Thornton and Commerce City. Northglenn sits between those documented impact areas. The storm frequency here is real and consistent.

Northglenn Was Built in the 1970s and Most of Its Roofs Have Been Replaced at Least Once Already
Northglenn’s median home build year is 1974. The city was developed almost entirely in the 1960s through the 1980s as a planned suburb, and nearly 87 percent of its homes were built before 2000. The dominant character is 1970s ranch homes and split-levels that have stood for decades and are now on their second or third replacement cycle.
A home built in 1972 or 1976 is not approaching its first replacement. It is past its second. The question for homeowners in these neighborhoods is not whether the roof is original, it never is. The question is whether the current installation was done correctly, whether ventilation was addressed when it was last replaced, and whether the materials used meet the standards Northglenn’s code now requires. Architectural shingles are rated 25 to 30 years. At 5,379 feet, with Adams County’s documented storm frequency, that timeline can run shorter than the warranty suggests.
Northglenn is fully built out. There is almost no new construction. The city reached its current scale in the 1980s and has been essentially stable since. What that means for homeowners is that almost every property in the city has a roof with history: previous contractors, previous installations, previous decisions about materials and ventilation that may or may not have been made well. A careful inspection before any replacement work begins is how you find out what is actually underneath.
Adams County Is One of Colorado's Most Active Hail Corridors and Northglenn Sits in the Middle of It
Northglenn’s position in the northern metro places it squarely in the path that storms take when they track northeast off the Front Range along the I-25 corridor. Flat, open terrain surrounds the city with no significant elevation changes to dissipate storm energy. When a cell forms over the mountains and moves east, it crosses through Adams County without losing meaningful intensity before it arrives.
Local contractors working this county consistently describe it as one of the most active hail corridors in Colorado. The Front Range averages 7 to 9 hail days per year, and at Northglenn’s elevation of 5,379 feet, hailstones arrive with more force than the same storm produces closer to sea level. There is less atmosphere to slow them down. Eastern Colorado regularly sees stones one to two inches in diameter during severe events. The 2024 storm confirmed that pattern directly over Northglenn.
UV intensity at altitude is a separate factor. At 5,379 feet, UV exposure degrades shingle granules faster than lower-elevation warranties account for. A roof in Northglenn can age faster than its rated lifespan implies, particularly on a home that has already been through one or two replacement cycles and may be carrying shingles installed to the minimum standard of an earlier era.
Northglenn Uses Drive-By Inspections and Requires Photo Documentation of Every Installation
Northglenn’s building inspection model for residential roofing is different from most other Front Range cities, and contractors who do not know this before they start a job will have problems at final.
The inspector does not access the roof. Northglenn uses a drive-by inspection for residential roofing finals. The inspector views the installation from the street. The contractor is not required to provide a ladder and no one needs to be home for the inspection. What is required, and what must be available for the inspector, is a complete photo record of the installation: underlayment down, ice and water shield installed, all documentation of what went under the shingles before they were nailed. If the photos are not there, the inspection does not pass.
This model puts real responsibility on the contractor to self-document code compliance correctly during installation. A crew that installs ice and water shield, nails shingles to the required ASTM wind resistance standard, and photographs every stage as they go will pass a Northglenn drive-by without any issue. A crew running a minimum-standard install without documentation will not. The drive-by model is not a lighter inspection. It is a different one, and knowing what it requires before tear-off begins is part of doing the job right here.
That One Construction Co. holds a current Northglenn contractor license, administered through SAFEbuilt and the city’s CommunityCore portal. We pull the permit, document the installation with photos throughout, and handle the final inspection. The current adopted code is the 2021 International Residential Code. Ice and water shield is required and must appear in the photo record. Northglenn’s building division has noted that a 2024 ICC code adoption is scheduled, with that transition expected in summer 2026. We stay current on where the city’s code stands before any job begins.
What That One Construction Co. Does on a Northglenn Claim
About 80 percent of what we do is insurance claim work, and we have staff whose job, every day, is talking with insurance companies. Not as a side task. That is their actual job. When a claim comes in from a Northglenn homeowner after a storm, we meet the adjuster on-site, document what we find, handle the estimate submission, and stay with the claim through reinspections and disputes if the initial settlement comes in short. Initial settlements routinely come in below actual replacement cost. Adjusters brought in from out of state after a major event may not know Adams County’s documented storm history or what a properly scoped re-roof costs in this market. We do, and we push back when the number is wrong.
For Northglenn homeowners, a contested insurance claim is a real financial event. Having a contractor who handles that process competently and completely, who pushes back on an underpaid settlement and stays with the claim until it resolves correctly, takes a significant burden off the homeowner. The documentation we put in front of an adjuster is specific, accurate, and built around what the code requires for this city. That is how underpaid claims get resolved.
We do not recommend replacement unless the roof needs it. The standard we use is the same one insurance companies use: a roof is a total loss at 50 percent damage. A lot of contractors call for full replacement at 10 percent. We do not. If a Northglenn roof can be repaired, we say so, even when a replacement job would pay better. Before any crew arrives, you get a prep email that tells you exactly what to expect: what the crew will do, in what order, what to have ready, and what the property will look like when they leave. No surprises on the day.
