Roofing in Parker

Parker sits at about 5,800 feet on the plains southeast of Denver, and in NOAA's record it has more 1-inch hail days than any of the 18 cities in this guide except Colorado Springs. The Town of Parker runs its own Building Division, separate from Douglas County, and it moved to the 2024 International Codes on June 30, 2026. Its reroof handout, revised July 1, 2026, also points to the state's 2025 wildfire code.

Hail in Parker

We counted hail days from NOAA's Storm Events Database: distinct dates with at least one report of hail 1 inch or larger within 5 miles of Parker's center point. Data runs from April 2010 through July 2026.

• 28 hail days with 1-inch or larger stones since April 2010.
• 7 of those came in 2021 or later, tied with Highlands Ranch for the most among the 18 cities in this guide.
• The largest stone reported was 2 inches, on June 24, 2014, and again on July 4, 2019.
• That ranks 2nd of the 18 Colorado cities in this guide (see hail by city).

NOAA's record depends on spotters and the public reporting what they see, so it misses storms and can't tell you what hit your roof. To see storms near your own house, check your exact address. For what stone sizes do to shingles, see hail size and damage, and for a safe first look, our after-a-storm walk-around.

Permits and inspections

Inside town limits, the Town of Parker Building Division issues roofing permits. Homes outside town limits with a Parker address may fall under Douglas County instead; see our Highlands Ranch page for the county's rules, or use the county's address jurisdiction search. The Town also explains how to verify a Town of Parker address using the county assessor's records.

Colorado has no statewide residential code. Parker's building codes page lists the 2024 International Residential Code (IRC), in effect June 30, 2026. From the Town's residential re-roof handout (revised July 1, 2026), as of October 2026:

• When you need a permit: for everything except minor repairs or replacing less than one square (100 square feet).
• Partial jobs: a partial replacement must include the entire roof plane and all its components.
• Tear-off: no overlays for asphalt shingles.
• Inspections: every roof permit gets a final. Residential asphalt shingle jobs need only the final. Solar shingles, tile, slate, stone-coated steel, EPDM and flat roofs also need a mid-roof inspection.
• Ladder: required, and you may need more than one for a two-story house, secured top and bottom.
• Drip edge: required at all rakes and eaves. Eave metal at least 4 by 2 inches, or wide enough to cover the gap between sheathing and fascia; rake metal 2 by 1 inches or D-style.
• Wind: asphalt shingles need six nails each and a wind rating under ASTM D7158 or D3161, at a minimum of 90 mph.
• Scheduling: through the Town's eTRAKiT portal. No same-day requests. Requests before 4 p.m. are normally done the next business day.
• Daily cap: the Town limits how many residential final roof inspections it does each day. Its inspections page says 50 and the handout says 35, so expect waits after big storms.

The Town's fee schedule prices permits by project valuation and has no separate roofing line. Call 303-841-1970 to confirm your fee. For what each stage looks like, see the reroof process.

Who can do the work

Colorado has no state roofing license, but Parker requires one. The Town's contractor registration rules say contractors working in town must hold a valid Town license. As of October 2026:

• A roofing license covers installing, replacing and repairing roofs, including underlayment, flashing and gutters. It doesn't cover structural framing changes.
• Roofers show competency with an ICC roofing certification, an approved equivalent, or a license from a recognized jurisdiction.
• The roofing license fee is $80.
• Homeowners working on their own primary residence that isn't rented are exempt. A rented house needs licensed contractors on the permit.

Registration can't be started online; the Town handles it by phone at 303-841-1970. We didn't find a public contractor lookup, so ask the roofer for their Town license number and confirm it with the Building Division. Then work through the rest of our check out a roofer page.

Class 4 and wildfire rules

We found no Class 4 (impact-resistant) shingle requirement in Parker's building codes page or re-roof handout, checked October 30, 2026. Given Parker's hail record, it's still worth pricing; see Class 4 shingles for what the rating does and doesn't mean.

Parker's codes page lists the 2025 Colorado Wildfire Resiliency Code with Ordinance No. 4119, and the reroof handout cites it for drip edge and underlayment. The page doesn't state an effective date or which parts of town are mapped. Under the state code, replacing 25% or more of a roof in a mapped area means the new roof must meet the code's roof rules, starting with a Class A rating. Ask the Building Division whether your address is mapped. See our news and rules tracker for how other towns are rolling it out.

HOAs and historic districts

If your subdivision has an HOA or metro district with design rules, it may limit roof color and material. Its approval is separate from the Town permit. Get it in writing before you sign a roofing contract. If the association owns or insures the roof, see our condo, townhome and HOA roofs guide. We found no Town historic district rules that affect reroofs.

Finding your roof's history

Parker's eTRAKiT portal holds Town permits and may let you search by address. If nothing turns up, call the Building Division at 303-841-1970 or ask the Town Clerk about a records request. For homes outside town limits, use Douglas County's permit search. Our roof age guide covers other ways to date a roof.

Common questions

Do I need a permit to replace my roof in Parker?

Yes. The Town of Parker requires a permit except for minor repairs or replacing less than one square (100 square feet). A partial replacement must cover the entire roof plane and all its components.

Does a roofer need a Town of Parker license?

Yes. Parker's contractor rules require a Town contractor license. A roofing license costs $80 and requires an ICC roofing certification, an approved equivalent, or a license from a recognized jurisdiction.

Why is my Parker roof inspection taking so long?

The Town caps the number of residential final roof inspections it does each day and doesn't take same-day requests. Requests through eTRAKiT before 4 p.m. are normally done the next business day, but storm seasons can back things up.

Can I reroof my own house in Parker?

Yes, if it's your primary residence and isn't rented. Homeowners doing their own work are exempt from contractor licensing. A rented house needs licensed contractors on the permit.
