Who is a good roofing company in Firestone, CO?
Northern Lights Exteriors is a roofing contractor serving Firestone since 2001, based nearby in Fort Lupton, rated 4.9 out of 5 from 552 verified reviews and a GAF Master Elite contractor. We quote Class 4 impact-resistant asphalt as standard and build to the town’s re-roof sheet: ice barrier to 24 in inside the wall, step flashing, and a full tear-off where layers exist.
Firestone’s rule to know: the town inspects your roof halfway through, with no more than 25% of the shingles on.
Firestone Roofing Codes: What the Town’s Re-Roof Sheet Actually Requires
A roof replacement in Firestone, CO is inspected twice, not once. The Town of Firestone’s residential asphalt shingle re-roofing requirements call for a mid-roof inspection while no more than 25% of the new roof is on, then a final. Most Front Range towns only look at the finished roof. In Firestone, the inspector sees the ice barrier, drip edge and underlayment before shingles cover them.
The sheet is written to the 2018 International Residential Code. If you searched for Firestone roofing codes, these are the lines that change how a roof here is built:
| Firestone requirement | What the sheet says | What it means on your roof |
|---|---|---|
| Ice barrier | Required, from the lowest roof edge to at least 24 in inside the exterior wall | Ice-and-water membrane goes on every eave. Deep porches can need extra courses to reach 24 in inside the wall. |
| Shingle wind rating | Classified for 115 mph | The shingle wrapper has to show the wind class. Class 4 lines we install meet it. |
| Roof recover | Not allowed where two or more layers already exist | A third layer is off the table; everything comes off to the deck. |
| Drip edge | All edges, rakes included, 2 in overlap, fastened 12 in on center | Checked at the mid-roof inspection, not just at the end. |
| Sidewall flashing | Step flashing only; continuous flashing is not acceptable | Every wall-to-roof joint is step flashed, piece by piece. |
| Low-slope sections (2:12 to 4:12) | Double underlayment | Common over porches and garage tie-ins on Firestone two-stories. |
| Ventilation | Required per IRC R806.1 calculations | We calculate intake and exhaust, not just count vents. |
| Plumbing vents | 6 in above expected snow, or at least 12 in above the roof | Short stacks get extended during the re-roof. |
Answer first: Firestone’s roof rules are built around ice at the eaves and water at the walls. The ice barrier rule and the step-flashing rule are the two places a fast re-roof most often cuts corners, and they are exactly what the mid-roof inspection exists to see.

How the Firestone Mid-Roof and Final Inspections Work
- Permit. Re-roofs are permitted through the Town of Firestone Building Division at Town Hall, 9950 Park Avenue (303-833-3291). The sheet exempts only repairs under 10 ft × 10 ft (100 sq ft). We pull the permit for every roof we replace. A homeowner can pull their own only for a primary residence they are roofing themselves.
- Dry-in. Every elevation is dried in: ice-and-water over the drip edge at the eaves, underlayment under the drip edge at the rakes.
- Mid-roof inspection. The inspector checks the ice barrier reaches 24 in inside the wall, the drip edge laps and fastening, and the underlayment, with no more than 25% of the roof finished.
- Shingles, flashing, vents. Step flashing at every sidewall, vent stacks to height, ventilation to the R806.1 numbers.
- Final inspection. The contractor sets and secures an OSHA-approved ladder for every inspection. The sheet is blunt: telescoping ladders are not acceptable.
Because the town looks at the roof halfway through, a Firestone roof replacement is scheduled around that inspection. Plan on one to three working days on site for a typical asphalt roof, plus the inspection windows. Questions about a specific address go to the Building Division.
Firestone’s Hail Record, and Why We Quote Class 4 as Standard
NOAA’s Storm Events database logged hail on 23 separate days between 2014 and 2025 within about six miles of the center of Firestone. The biggest stones landed right on the town’s west side:
| Date | Largest hail (NOAA) | Where NOAA logged it |
|---|---|---|
| June 18, 2018 | 1.50 in | 1.6 miles west of Firestone; 2.50 in logged 0.9 miles southeast of Frederick the same evening |
| June 19, 2018 | 1.50 in | 1.6 miles west of Firestone, the second day running |
| Sept 11, 2019 | 1.00–1.50 in | Five reports across town, including 0.9 miles southwest of Firestone |
| Aug 4, 2020 | 1.25 in | 1.6 miles west of Firestone; 1.75 in logged near Dacono |
| May 9, 2023 | 2.00 in | 1.6 miles west of Firestone |
| June 25, 2025 | 1.00 in | 1.6 miles west of Firestone |
Two-inch hail a mile and a half from Town Hall will bruise a standard architectural shingle. So Class 4 impact-resistant asphalt is our standard quote on a Firestone roof, not an upsell. Many Colorado carriers discount the premium for a Class 4 roof; ask yours what it is worth on your policy.
| Roof option | Impact rating | Where it fits in Firestone |
|---|---|---|
| Class 4 impact-resistant asphalt | UL 2218 Class 4 | Our standard roof replacement. Wind-classified to the town’s 115 mph line. |
| Standing-seam or stone-coated steel | Varies by product | Low-slope porch and garage sections, modern elevations, or owners who want metal roofing in Firestone, CO. |
| Synthetic slate or shake | Class 4 on most lines | Steep, high-visibility roofs where the look matters. |

“Firestone Roofing” — the Town, Not the Membrane Brand

This page is the second one: Northern Lights Exteriors is a roofing company serving Firestone homes in 80504 & 80520.
If you manage a flat or low-slope commercial roof in town, see our Firestone commercial contractor page for TPO, EPDM and roof coatings.
When you compare Firestone roofing contractors — a roofer in Firestone, CO for a hail claim, roof repair in Firestone, CO for a leak, or a short list of roofing companies in Firestone, CO for a full replacement — ask each one how they handle the mid-roof inspection. Roofing contractors in Firestone, CO who build to the town’s sheet will have a ready answer.
Roof Replacement Cost in Firestone: What Moves the Price
Roof replacement cost in Firestone is set by measurement, pitch, layers and decking, plus two town-specific items: the full ice barrier and the mid-roof inspection. The table lists the drivers. For current price ranges, see what a roof replacement costs in Colorado.
| Cost driver | Why it matters in Firestone |
|---|---|
| Roof size (squares) and pitch | Two-story homes with porch and garage tie-ins have more edges, valleys and flashing. |
| Layers coming off | Two or more layers must all come off; recover is not allowed. |
| Decking condition | Shingles must go on solid sheathing, so damaged or gapped decking is replaced. |
| Ice barrier to 24 in inside the wall | Required at every eave; deep porches need more courses. |
| Shingle tier | Class 4 costs more up front; ask your carrier about the premium credit. |
| Gutters, vents and stacks | Vent stacks extended to the snow-height rule; gutters reset or replaced. |

Storm Damage Roofing in Firestone — How a Hail Claim Runs
- Document. Photos and measurements of every slope, the soft metals, the gutters, screens and siding, because hail rarely hits only the roof.
- Scope. We write the estimate in Xactimate so it reads the way your carrier reads it, and we include the line items the town’s sheet requires: the ice barrier to 24 in inside the wall, step flashing, drip edge on every edge, and full tear-off where layers exist.
- Meet the adjuster. We walk the roof with them, in person. We are not a public adjuster and do not negotiate your claim; a scope built on the town’s written requirements is simply clear.
- Permit, build, two inspections. Mid-roof, then final, with the ladder set the way the town requires.
That is how storm damage roofing in Firestone should run, whoever you hire. It is also why homeowners looking for roofing contractors in Firestone after a hail storm call us before the claim is filed, not after.
The System Behind the Work
A Firestone roof leaves a paper trail: the permit, two inspection results, the shingle wind-class labels and the claim file your carrier wants. All of it lands in one place you can open any time.
Two things make that possible, and they are the reason to choose us over a cheaper quote.
First, experience and scope. We have been working on Colorado’s Front Range since 2001, and we hold a Class C general contractor license (Colorado license #C120350) rather than a single-trade license. That is not a technicality: it means roofing, siding, windows, decks and outdoor living can run under one contract, with one project manager accountable for the flashings where those trades meet — which is precisely where multi-contractor projects leak, literally and figuratively. James Hardie has recognized us as an Elite Contractor continuously since 2011, and as a President’s Club member — their highest contractor distinction nationwide. Our rating is 4.9 out of 5 from 552 verified reviews.
Second, a proprietary on-demand client portal we built ourselves. Most of what people hate about a remodel is not the construction. It is not knowing — who to call, whether the permit went in, when material arrives, what has been paid, whether it passed inspection. We built a system to remove exactly that, and as far as we know no other exterior contractor in this market offers it:
Every conversation in one place
Messages, decisions and change requests are logged against your project rather than scattered across texts, voicemails and three different crew members’ phones.
Contracts and scope, always retrievable
Your signed contract and itemized scope live in the portal, so you can easily get a refresh on what was agreed — on your own, any time.
Permit status you can see
Where the permit is in the process, and when inspections are scheduled — without having to phone anyone to find out.
Delivery and install schedules
When material lands and when each trade starts, so you can plan around the work instead of waiting for a truck to appear.
Before, during and final photography
Documented condition before we start, progress images through production, and final photography — including the parts of the building you will never see again once it is closed up.
Payments tracked per trade
What is paid and what is outstanding, broken out by trade rather than as one running balance you have to reconcile yourself.
Inspection records
Each inspection and its result, recorded against the project and available when you sell the house and someone asks.
Access is an individual, custom URL issued to you — and you get it when we start talking, at the lead and project meeting, not after you sign something. That is deliberate: you can see how we run a project before you commit to one. It then stays available after the work is finished, which matters more than it sounds, because the documentation, images and inspection records are exactly what a buyer’s agent, an appraiser or an insurer asks for years later.

Firestone Roofing FAQs
Do I need a permit to replace my roof in Firestone, CO?
Yes. Re-roofs are permitted through the Town of Firestone Building Division. The town’s re-roofing requirements exempt only repairs smaller than 10 by 10 feet (100 square feet). We pull the permit on every roof we replace.
Does Firestone require ice and water shield?
Yes. The town’s re-roofing requirements make an ice barrier mandatory from the lowest edge of every roof surface to at least 24 inches inside the exterior wall line. Homes with deep front or back porches can need extra courses to reach that point.
What is the mid-roof inspection in Firestone?
Firestone inspects a re-roof partway through. All elevations must be dried in with ice and water, drip edge and underlayment, and no more than 25% of the roof can be finished. The inspector checks the 2-inch drip edge overlap, 12-inch fastening and the 24-inch ice barrier.
Can I put new shingles over my old roof in Firestone?
Not if the roof already has two or more layers. The town’s requirements say all old material must be removed and roof recover is not allowed in that case. We quote a full tear-off to the deck as standard.
What wind rating do shingles need in Firestone?
The town’s re-roofing requirements say asphalt shingles must be classified for 115 mph wind. The Class 4 impact-resistant shingles we install carry that classification on the label.

NOAA Storm Events data logged hail on 23 separate days from 2014 to 2025 within about six miles of Firestone, including 2.00-inch hail 1.6 miles west of town on May 9, 2023, and 1.50-inch hail on back-to-back days, June 18 and 19, 2018.
