Roof Repairin Colton, CA
A Colton re-roof is permit work: the City's handout asks for a permit on a new roof, a re-roof and any repair over 25 percent of the roof. Climate Zone 10 adds a cool roof and, when attic sheathing is replaced, a radiant barrier. Solar and panel upgrades also involve Colton's own electric utility.
Colton is a railroad town first. The City's History page says the first formal town was laid out on a grid after the Southern Pacific arrived in 1875, and that railroad workers in south Colton often built their own houses from the disassembled wooden crates used for rail shipments. Sources disagree on the incorporation year, 1877 in the 2025 Hazard Mitigation Plan and 1887 on Wikipedia, so we rely on neither. ACS 2024 five-year estimates count 17,856 housing units, 51.4 percent of them built before 1980 and 29.7 percent before 1960, so many roof decks here sit on houses at least 46 years old.
On a roofing job, MDG Builders (CSLB #1040337) acts as the general contractor: we write the scope, work out which Colton review applies and keep the calendar, and a licensed C-39 roofing subcontractor does the tear-off and the new covering. Our roofing page carries the sourced prices and the Colton overview lists every trade we manage here. Permits come from the Building & Safety Division, and the guides for San Bernardino and Riverside show how two neighbors run the same work. The City's Municipal Code host returned an HTTP 403 error to our request, so the code text below comes from GoCodebook, a third-party mirror with text as of October 4, 2026, and each section should be confirmed with the City.
What Colton's permit handouts, fire code table and energy rules say about roofs
Where roofing permits come from in Colton: City of Colton Development Services Department, Building & Safety Division.
- Colton requires a permit for roof installation and for re-roofing or roof repairs exceeding 25 percent of the roof; minor patching under 25 percent is exempt (permit handout).
- The residential re-roof handout (written for the 2022 codes) says permits are issued to a C-39 roofing contractor, the property owner, or a B contractor only with the multiple-trade requirement; no more than one overlay of asphalt shingles is allowed (two layers maximum); tile over 6 psf or any tile over existing coverings needs engineer calculations; metal roofing needs an ICC-ES or equal report; and a permit is valid 180 days from the last approved inspection.
- The same handout says Colton is in Climate Zone 10, that replacing a residential roof surface requires a cool roof there, and that a continuous radiant barrier is required when roof sheathing over an attic is replaced, with a CF1R-ALT-01 certificate filed at permit and a CF2R-ENV-04 completed before final.
- That handout also lists the City's roof inspections (tear-off or sheathing, roof nail, an extra inspection when roof-mounted solar is removed and remounted, and final), an OSHA ladder secured to the roof, and smoke and carbon monoxide alarms installed before final.
- The newer 'Reroof Building Permit Requirements' handout says a tear-off re-roof needs two inspections (roof sheathing, then final) and an overlay (maximum two layers) needs final only.
- That newer handout also says Planning approval is required before the permit if the property is in a Specific Plan, a historic zone or a designated Historic Landmark, and that all documents must be physical copies at submittal, with a signed CF1R residential alteration reroofing form.
- Colton's code table sets the minimum roof covering at Class A for construction Types I through III and Class B (Class A in Very High Fire Hazard Severity Zones) for Types IV and V, which covers ordinary wood-frame houses, for new buildings, re-roofs and additions (15.06.200 and 15.07.070). (read in GoCodebook's third-party mirror of the Colton Municipal Code, 2026-10 edition, roofing sections, text as of 2026-10-04)
- Colton has an expedited small residential rooftop solar process (Chapter 15.60): routine operation and maintenance or like-kind replacements with no structural alteration need no permit. (read in GoCodebook's third-party mirror of the Colton Municipal Code, 2026-10 edition, roofing sections, text as of 2026-10-04)
Do I need a permit to repair or replace a roof in Colton, and what is the 25 percent line?
Yes for a new roof or a re-roof, and for a repair that reaches more than 25 percent of the roof. The City's handout on when a building permit is needed lists roof installation, re-roofing and repairs over 25 percent as permit work and treats minor patching under 25 percent as exempt. The handout says its list is not all-inclusive, so a leak repair near the line is a phone call to 909-370-5079 before anyone climbs a ladder.
The City's residential re-roof handout, written for the 2022 codes, says permits go to a C-39 roofing contractor, the property owner, or a general building contractor only with the multiple-trade requirement. That reading points to the roofing subcontractor as permit holder on a roof-only job, a point we confirm with the counter. Public counter hours are 7:30 am to 5 pm Monday through Thursday, with no Friday service. One catch: the City's eTRAKiT list of online permits does not name re-roofing, although the handouts still describe it, so confirm how to submit.
Get the permit holder's name and the percentage of roof replaced into the written proposal.
Can new shingles go over the old ones in Colton, and what does the inspector check?
One overlay is the limit. The re-roof handout allows no more than one overlay of asphalt shingles, two layers in all, so a roof that already carries two has to come off. Tile heavier than 6 pounds per square foot, or any tile laid over existing coverings, needs engineer calculations, and metal roofing needs an ICC-ES or equal evaluation report.
The City's two handouts count inspections differently. The 2022-era sheet lists tear-off or sheathing, roof nail and final inspections, with an extra visit when roof-mounted solar is removed and remounted, while the newer Reroof Building Permit Requirements sheet says a tear-off needs two inspections, sheathing and then final, and an overlay needs only a final. We cannot tell which list an inspector follows, so ask which visits to book. Either sheet expects an OSHA-compliant ladder secured to the roof and smoke and carbon monoxide alarms installed before final.
A permit stays valid 180 days from the last approved inspection, so a back-ordered tile shipment can run down the clock. Inspections are requested on the Inspection Line, 909-370-5131, by 4 pm for the next day, and Thursday and Friday calls roll to Monday.
Ask the counter which inspection list applies and book the sheathing visit before the underlayment goes down.
How old are Colton roofs, and does a historic district change the roofing material?
Roof age follows the neighborhood. ACS 2024 counts 1,431 homes from 1939 or earlier, 1,301 from the 1940s, 2,564 from the 1950s and 4,539 from the 1980s, Colton's biggest decade at 25.4 percent. The City's own history describes a post-World War II building frenzy and then explosive subdivision growth 30 to 40 years later, with Interstates 10 and 215 drawing transportation industries. Wikipedia adds that 1953 freeway construction bulldozed part of historic downtown.
In a designated historic district or on a landmark, a change of roofing material counts as an alteration under Chapter 15.40 and needs a Certificate of Appropriateness. The City maps six districts (9th Street, Agua Mansa, Citrus Park, La Cadena, San Salvador and Terrace) and 53 landmarks, and the newer re-roof sheet says Planning must approve before the permit when the property is in a Specific Plan, a historic zone or a landmark. Ordinary maintenance that changes no design, material or appearance is not blocked, so a like-for-like repair is a question for the Preservation Officer.
- Stains or damp spots on ceilings under the roof deck
- Cracked, slipped or missing covering
- Flashing lifting at walls, vents or valleys
- Deck boards that flex between the rafters
Look up the address in the City's Property Viewer before choosing a new covering.
Is my Colton roof in a Very High fire zone, and what class of roof do I need?
In the hills, probably. The 2025 Hazard Mitigation Plan describes the La Loma Hills and Box Springs Mountains in southern Colton as Very High Fire Hazard Severity Zones, the flatter southwest as Moderate as far north as Slover Avenue, and Moderate pockets north of the Santa Ana River and near the Interstate 10 and 215 interchange. It counts about 7,122 residents in Very High zones and names the June 1981 Colton Fire, about 4,051 acres near Reche Canyon Road, as the largest local fire. The State Fire Marshal's recommended 2025 maps list Colton, but we found no ordinance adopting them and no parcel-level zone, so the map for an address is a question for the City.
Colton's code table sets the minimum roof covering at Class A for construction Types I through III and at Class B, or Class A in Very High zones, for Types IV and V, which covers ordinary wood-frame houses (15.06.200 and 15.07.070). Fire service comes from the City's own Colton Fire Department at 303 East E Street, not San Bernardino County Fire. Reche Canyon Road is the only way in or out of the Reche Canyon neighborhood, so dumpsters, cranes and material trucks there need an access plan.
Have the proposal name the roof class and the map or zone source behind it.
What do 103 days above 90 degrees and Santa Ana winds do to a Colton roof?
NOAA's 1991 to 2020 normals for the Riverside Citrus Experiment Station, the nearest full station we found, about 6.4 miles south-southwest at nearly Colton's elevation, show 9.92 inches of rain a year, 7.61 of it from December through March and only 0.03 inch in July and again in August. Average highs run from 69.5 F in January to 96.6 F in August, with about 103 days at or above 90 F and about 24 at or above 100 F. A deck bakes for months and then takes most of its water in one season.
Wind is the other load. Colton's code sets 110 mph for new structures under the Residential Code, and the Hazard Mitigation Plan lists Santa Ana gusts of 70 mph on October 9, 2017 and a January 7, 2025 windstorm with 40 to 60 mph winds, adding that winds are strongest at the bottom of canyons such as Reche Canyon. The re-roof handout puts Colton in Climate Zone 10, which requires a cool roof when a residential roof surface is replaced and a continuous radiant barrier when attic sheathing is replaced, with a CF1R-ALT-01 certificate at permit and a CF2R-ENV-04 before final.
Ask to see the cool roof product data and the energy forms before the permit is filed.
How does Colton's own electric utility affect a re-roof with solar or a panel upgrade?
Inside Colton, electric work goes to the City, not to Southern California Edison. The City's Electric Utility Information page says the utility was established in 1887, calls it the oldest founded utility in San Bernardino County, and says the City owns its power plant, five substations and the lines inside Colton, with about 16,818 residential customers in 2023. The City's permit list names a Main Service Panel Change Out/Upgrade permit and an Electric Load Questionnaire required for all electric upgrades.
Solar is on the City's list of building permits, and Chapter 15.60 says routine operation and maintenance or like-kind replacement of a small rooftop system with no structural alteration needs no permit. Pulling panels for a tear-off and setting them back is a different step, since the re-roof sheet adds an inspection when solar is removed and remounted. The eTRAKiT page says expediting is not available through Public Works Electric Utilities, and the City publishes no turnaround, so a panel upgrade tied to a roof date needs its own lead time.
Have the electrician start the Load Questionnaire before the roof date is set.
How much does a new roof cost in Colton, and who should I hire?
We found no Colton price survey, so these are Los Angeles numbers and an Inland Empire bid can differ. Angi's Los Angeles roof replacement guide, updated July 31, 2026, shows a typical $10,256 to $24,963 with a $17,271 average, asphalt at $4 to $12 a square foot, tile at $7 to $15 and metal at $7 to $16, plus $1,000 to $3,000 for tear-off and $500 to $1,000 to detach and reinstall solar panels. Remodeling magazine's 2025 Cost vs. Value report prices a fixed reference asphalt roof in Los Angeles at $36,417 and does not publish the roof size. For planning we use about $10,000 to $25,000 for asphalt, $15,000 to $37,000 for tile and $20,000 and up for metal, with deck repair extra.
Roofing is CSLB class C-39, and Business and Professions Code 7159 caps a down payment at $1,000 or 10 percent of the price, whichever is smaller. Dust and debris carry local rules too: South Coast Rule 403 bars dust visible past the property line, and the City says it contracts exclusively with CR&R for trash, so ask where a dump trailer will come from. Check credentials with our license guide and read how general contractors use subcontractors for who answers to whom.
Roofing photos from Colton and nearby communities
Roofing scenes tied to Colton places such as Downtown Colton, South Colton, Cooley Ranch and the La Loma Hills, and to nearby communities such as Grand Terrace, Loma Linda, Bloomington and Highgrove, from tear-offs and underlayment to tile repair and flashing work.
Where these Colton roof figures come from
Each roofing price, with its source and date, is listed in the table on the roofing page, and the California roofing cost guide explains why a survey average and a fixed reference roof sit so far apart. Roof work tends to bring other exterior jobs along, and the Colton rules for them are on the fencing page, the painting page and the kitchen remodeling page. To compare another Inland Empire counter, read the roofing guide for Rialto.
| What it covers | Typical range |
|---|---|
| Asphalt shingle, typical single-family roof | $10,000 to $25,000 |
| Concrete or clay tile | $7 to $15 per sq ft |
| Metal | $7 to $16 per sq ft |
| Remodeling Cost vs. Value 2025, Los Angeles | Asphalt $36,417. metal $62,069. |
| Extras | Tear-off $1,000 to $3,000. solar detach and reset $500 to $1,000. |
Colton roofing questions, answered
Do I need a permit to replace my roof in Colton?
Yes. The City's permit handout lists roof installation, re-roofing and repairs over 25 percent of the roof as permit work, and a re-roof handout explains the inspections. Minor patching under 25 percent is exempt. Call the Building & Safety counter at 909-370-5079 before treating a repair as exempt, because the handout says its list is not all-inclusive.
What is the 25% rule for roofing?
In Colton it is a permit line, not an insurance rule: the City's handout requires a permit for repairs over 25 percent of the roof, and minor patching under that is exempt. We found no Colton rule that ties 25 percent to a fire upgrade. Have the roofer measure each plane and print the percentage on the proposal.
How much should a 2000 sq ft roof cost?
Applying Angi's Los Angeles range of $4 to $12 a square foot, 2,000 square feet of asphalt runs about $8,000 to $24,000, and tile at $7 to $15 runs $14,000 to $30,000, before tear-off and deck repair. That is arithmetic, not a bid. Roof area is usually larger than floor area, and no Colton survey exists.
Does Colton require a Class A roof?
For ordinary wood-frame houses, Class B, but Class A in Very High Fire Hazard Severity Zones, according to the code table in 15.06.200 and 15.07.070, which applies to new buildings, re-roofs and additions. Most of southern Colton's hills are mapped Very High, so ask the City which zone your lot is in.
Is my Colton roof in a fire hazard zone?
We cannot say for your lot. The Hazard Mitigation Plan puts the La Loma Hills and Box Springs Mountains in Very High zones, and the State Fire Marshal's recommended 2025 maps list Colton, but we found no ordinance adopting them or a parcel lookup. Ask the Building Division, and note the City has its own fire department.
Do I need a cool roof or radiant barrier in Colton?
Yes when a residential roof surface is replaced. The City's handout puts Colton in Climate Zone 10, which requires a cool roof when a residential roof surface is replaced and a continuous radiant barrier when sheathing over an attic is replaced. A CF1R-ALT-01 certificate is filed at permit and a CF2R-ENV-04 is completed before final.
Can I put a second layer of shingles over my Colton roof?
Once. The City's handout allows no more than one overlay of asphalt shingles, two layers in all, and an overlay needs only a final inspection under the newer sheet. A roof that already has two layers has to be torn off. Tile over existing coverings is not an overlay and needs engineer calculations.
What is the best month to replace a roof in Colton?
The driest are June through August: NOAA's normals show 0.08 inch in June and 0.03 inch in July and August, against 7.61 inches from December through March. But August highs average 96.6 F and about 24 days a year reach 100 F. Spring and early fall trade a little rain risk for cooler decks.
Do I need a permit to take solar panels off for a Colton re-roof?
Ask the counter. Chapter 15.60 exempts routine maintenance or like-kind replacement of a small rooftop system with no structural alteration, but the City's re-roof handout adds an inspection when roof-mounted solar is removed and remounted. Plan for that visit, and for a longer wait if the electric utility is involved.
Can a general contractor replace my roof in Colton?
A general contractor can manage it. MDG is licensed as CSLB #1040337 and hires a licensed C-39 roofer for the field work. The City's handout names a C-39 contractor, the owner, or a B contractor with the multiple-trade requirement as permit holders, so we confirm who pulls the permit. Ask the roofing firm for its license number and a current certificate of insurance before the contract is signed.
