Roof Repairin Tustin, CA
Roof repair in Tustin is permitted by the City's own Building Division, and the Ordinance 1569 minimum for a new or substantially replaced roof is Class B. The City's older reroofing guide asks for Class A in the East Tustin Specific Plan Hillside District, and homes in Old Town also need a Certificate of Appropriateness.
Tustin roofs sit on three different generations of housing. The Census Bureau's ACS 2024 one-year estimates count 30,118 housing units, about 46 percent of them built before 1980 and only about 4 percent before 1960, with the 1960s the largest decade at 23.7 percent. Columbus Tustin and Nelson Stafford bought 1,300 acres of the old Rancho Santiago de Santa Ana in 1868, the city incorporated on September 21, 1927, and after the Santa Ana Freeway arrived in 1955 tracts replaced the citrus groves. A much newer layer followed on the old Marine Corps Air Station and in Tustin Ranch.
On a roofing project, MDG Builders (CSLB #1040337) writes the scope, takes the permit questions to the City and keeps the schedule, while a licensed C-39 roofing subcontractor does the tear-off and installation. Our roofing page holds the sourced prices, the Tustin overview lists every trade we manage in this part of Orange County, and the guides for Irvine, Orange and Santa Ana show how neighboring cities word the same rule. Roofing often leads to fencing, painting or a kitchen remodel on the same property.
What Tustin's Ordinance 1569 and reroofing guide say about roofs
Where roofing permits come from in Tustin: City of Tustin Community Development Department, Building Division.
- The City's reroofing guide (revised August 2013) says a reroof needs a permit application with fees, the manufacturer's specifications for the new roofing, an HOA stamp or approval letter where there is an HOA, and a Certificate of Appropriateness from the Director for homes in the Cultural Resources Overlay District. It says permits are usually issued over the counter.
- The City's reroofing guide says the minimum roof covering classification for any building is Class B, and Class A is required for all buildings in the Hillside District as defined in the East Tustin Specific Plan or where Table 1505.1 as amended by the City requires it. That guide predates the 2025 code cycle, so confirm the current Hillside District requirement with the Building Division.
- Ordinance No. 1569 amends the 2025 California Building Code and Residential Code so that the entire roof covering is at least Class B (fire-retardant) when more than 50 percent of the roof area is replaced in any one-year period, on every new structure, and on any covering applied in alteration, repair or replacement, in areas outside the Fire Hazard Severity Zones and Wildland-Urban Interface. Table 1505.1a lists Class B for every construction type, and the table's footnote says Part 7, the California Wildland-Urban Interface Code, can require more.
- Ordinance No. 1569 (Residential Code R902.1) counts brick, masonry, exposed concrete roof deck, metal sheets and shingles, clay or concrete tile and slate on noncombustible decks as Class A assemblies, and defines fire-retardant-treated wood shakes and shingles as those meeting UBC Standard 15-3 or 15-4 full-cell pressure treatment and qualified under UBC Standard 15-2 for use on Class A or B roofs.
- Under the City's reroofing guide, existing roofing must be removed down to the deck where it is water soaked or deteriorated, is wood shake, slate, clay, cement or asbestos-cement tile, or already has two or more roof coverings. When the Building Official allows reroofing over existing roofing, loose gravel and debris must be cleaned off and blisters and buckles cut out and made smooth.
- The reroofing guide sets slope limits: asphalt shingles only on roof slopes of 2:12 (17 percent) or steeper, and clay or concrete tile only on slopes of 2.5:12 (21 percent) or steeper, with double underlayment required below a 4:12 (33 percent) slope for both.
- The reroofing guide requires engineering calculations and roof framing plans by a California licensed architect or engineer when removing roofing and replacing it with any material weighing 7 pounds per square foot or more. For a residential roof laid over existing roofing, extra weight above 4 psf requires drawings and calculations signed by a California registered architect or civil engineer.
- The reroofing guide lists a pre-roof inspection (before felt or underlayment is laid over existing roofing, or after the old roofing is removed, sheathing is exposed and diaphragm nailing is in) and a final inspection, with the new roofing specifications and any cool roof label on site. It requires 24 hours' notice, says existing equipment screens need Building Inspector and Planning approval before reinstallation, and says PVC pipe is not approved for rooftop condensate drains.
Sources for these rules
Does a roof in Tustin have to be Class A or Class B?
Class B is the floor in the ordinance text. Ordinance No. 1569, which adopts the 2025 California codes with Tustin amendments, requires the whole roof covering to be at least Class B on every new structure, on any covering applied in an alteration, repair or replacement, and whenever more than 50 percent of the roof area is replaced in one year, in areas outside the fire zones and the wildland-urban interface. Its table lists Class B for every construction type, and a footnote says the state wildland-urban interface code can require more.
Class A is where the older paperwork gets specific. The City's reroofing guide, revised in August 2013, says Class A is required for all buildings in the Hillside District defined in the East Tustin Specific Plan. We did not read that plan or its district map, and the guide predates the 2025 code cycle, so call the Building Division at 714-573-3130 before you order materials for a hillside house. The City's page still words the ordinance as proposed, while the council packet of November 18, 2025 shows adoption and an effective date of January 1, 2026.
Ask for the fire class of the new covering and of any roofing that stays, written on the proposal.
Which parts of Tustin are in a fire hazard severity zone?
Some parts of the city are, though we cannot tell you which streets. CAL FIRE and the State Fire Marshal released the 2025 Local Responsibility Area maps on March 24, 2025, and the City says its map designates portions of Tustin as Very High, High and Moderate. A City Council item dated June 3, 2025 asked for an ordinance adopting the maps, but the pages we read do not confirm that it passed.
The tier for a given street was not readable in the City's PDF, which is an image, so we name no neighborhood as Very High or High. Look up the parcel on the City's fire hazard severity zone page and CAL FIRE's viewer. Plan reviews submitted on or after January 1, 2026 fall under the 2025 California Wildland-Urban Interface Code, and fire service in Tustin comes from the Orange County Fire Authority, which serves 23 cities and three stations cover Tustin.
Write the mapped zone for your parcel into the contract before the roofer picks a material.
Can I re-roof a house in Old Town Tustin without a Certificate of Appropriateness?
Not always. Old Town is the original townsite, platted around 1870, and the City's 2021 historic resources survey finds that most of its earliest houses date to the 1880s, with the Hubbard House from 1876, plus Victorian cottages and Craftsman bungalows from about 1910. The City Council created the Cultural Resources Overlay District on June 20, 1988, and the reroofing guide asks for a Certificate of Appropriateness from the Director for homes inside it.
The code text we read requires that certificate before exterior features are altered when the work needs a City building permit, with an exception for ordinary maintenance or repair that does not change the design, exterior material or original appearance. Swapping one roofing material for another, or changing the look of a cottage roof, is the kind of change that tests that line. That text came from a third-party mirror of the City code on Zoneomics, because the official Municode site was not read, so confirm the wording with Planning at 714-573-3140 and ask whether the parcel is inside the district. The Old Town design guidelines were not available to us either.
Does roof replacement in Tustin need a permit, and how long does the permit last?
A re-roof needs one. The City's reroofing guide asks for a permit application with fees, the manufacturer's specifications for the new roofing, an HOA stamp or approval letter where an association exists, and the Certificate of Appropriateness for district homes, and says permits are usually issued over the counter. Applications and payments go through the Citizen Self Service portal, and the City says it collects permit fees only through that portal or at the City Hall Finance counter. We print no fee, because we did not read the fee schedule.
The guide lists two inspections, one before underlayment goes down or after the old roofing is off and the nailing is in, and one at the end, with 24 hours' notice. Permit life is where City documents disagree. The Permits Process page says 180 days unless work is active, the Building FAQ says 360 days if work has not started, and Ordinance 1569 says 12 months to start and 180 days of suspension or abandonment. State both sides to your roofer and ask the Building Division which one governs your permit.
When does Tustin require a full tear-off, and what slope and weight limits apply?
The reroofing guide sets the tear-off rules in plain terms. Existing roofing must come down to the deck when it is water soaked or deteriorated, when it is wood shake, slate, clay, cement or asbestos-cement tile, or when the roof already has two or more coverings. Where the Building Official allows a re-roof over existing roofing, loose gravel and debris come off and blisters and buckles are cut out and smoothed.
Slope and weight come next. Asphalt shingles are allowed only at 2:12 or steeper and clay or concrete tile at 2.5:12 or steeper, with double underlayment below 4:12 for both. Replacing roofing with anything weighing 7 pounds per square foot or more calls for framing calculations from a California licensed architect or engineer, and extra weight above 4 pounds per square foot over an existing roof needs drawings signed by an architect or civil engineer. The guide also bars PVC for rooftop condensate drains and requires approval before equipment screens go back up. It dates from 2013, so confirm each limit against the current code.
How much does roof replacement cost in Tustin, and what should a roofing quote say?
We found no Tustin roof price survey, so the numbers below describe Los Angeles and a Tustin proposal will differ. Angi's Los Angeles roofing survey, last updated July 31, 2026, lists asphalt at $4 to $12 per square foot, tile at $7 to $15 and metal at $7 to $16, with tear-off adding $1,000 to $3,000 and removing and resetting solar panels adding $500 to $1,000. The 2025 Cost vs. Value report from Remodeling magazine prices a reference Los Angeles asphalt roof at $36,417 and a metal roof at $62,069, but it does not publish the roof size, which explains why those figures sit so far above Angi's average of $17,271.
Roofing is CSLB class C-39, and the state's $1,000 unlicensed work limit does not apply when a permit is required, as it is for a Tustin re-roof. A contract must be in writing under Business and Professions Code 7159, and the deposit may not exceed the lesser of $1,000 or 10 percent. Check any license with our contractor license guide, read how general contractors use subcontractors to see who answers for what, and see the California roof replacement cost guide for why surveys differ.

Tustin roofing questions, answered
Do I need a permit to replace my roof in Tustin?
Yes. The City's reroofing guide calls for a permit application with fees and the manufacturer's specifications, and says permits are usually issued over the counter. Homes in an HOA need the association's stamp or letter, and Old Town homes need a Certificate of Appropriateness. Ask the Building Division at 714-573-3130 how long your permit stays valid, because City documents disagree.
What is a Class A roof, and does Tustin require one?
Class A is the top fire-test rating. Tustin's Ordinance 1569 sets Class B as the minimum for new and substantially replaced roofs outside the fire zones, while the City's older reroofing guide requires Class A in the East Tustin Specific Plan Hillside District. Because that guide predates the 2025 code, confirm your address with the Building Division.
Should I repair or replace my roof?
Repair when damage is local and the deck beneath it is sound, and replace when the covering is failing across whole slopes or the deck feels soft. Tustin adds one rule: replacing more than 50 percent of a roof in a year triggers the Class B minimum for the entire covering. Ask for photographs of the damage before you decide.
What is the 25 percent rule for roof repairs?
We found no Tustin code section with that name, and the sites that quote it rarely cite one. The percentage that matters in Tustin is 50 percent of the roof area replaced in one year, which triggers Class B for the whole covering under Ordinance 1569. Ask the counter how it measures that on your roof before you phase a job.
How much does it cost to reroof a house in Tustin?
Price it by roof area, because house size misleads. Angi's Los Angeles data shows asphalt at $4 to $12 a square foot, tile at $7 to $15 and metal at $7 to $16, and Cost vs. Value 2025 puts a reference asphalt roof at $36,417. We found no Tustin survey, so a measured written proposal is the real price.
Is my Tustin home in a fire hazard severity zone?
Possibly. The City says the 2025 state map designates portions of Tustin as Very High, High and Moderate, but we could not read which streets fall in each tier and could not confirm that the Council adopted the map by ordinance. Check your parcel on CAL FIRE's viewer and copy the result into your roofing contract.
How many layers of roofing are allowed in California?
We did not find a statewide layer count that we could cite for Tustin. The City's reroofing guide requires a tear-off to the deck when a roof already has two or more coverings, and also for wood shake, slate, clay, cement or asbestos-cement tile. Ask the Building Division whether an overlay is allowed on your roof.
Can you stay in your house during roof replacement?
Usually yes, since the work happens above the ceiling, though it is loud and crews are on site all day. We did not read Tustin's construction hours, so ask the roofer for a daily schedule. The City also says construction materials and dumpsters need the City Engineer's written approval before they sit on public property.
What is the best time of year to replace a roof in Tustin?
Summer is the driest choice, since NOAA's Irvine Ranch station, about 5.1 miles east, records 10.18 of its 13.06 yearly inches from December through March. The tradeoff is heat, with 61.6 days a year at or above 90 F there against 12.8 at John Wayne Airport. Ask crews to start early and to cover the deck each night.
Can a general contractor do roofing in California?
A general contractor can manage a roofing job, but the roofing itself is CSLB class C-39 work. MDG holds the contract and brings in a licensed C-39 subcontractor, and you can ask for that license number and certificate of insurance. Whether a Class B contractor may take a roofing-only contract is a question for CSLB.
