Roof Repairin Compton, CA
Roof repair in Compton is a Building and Safety matter, and the City's re-roof guidelines call for three inspections on a replacement: tear-off, sheathing and final. The Municipal Code's exemption list never mentions roofing, so ask before assuming a patch is exempt. A roof replacement needs at least a Class B covering.
Compton was incorporated on May 11, 1888, yet most roofs over it are far newer. The 2024 American Community Survey counts about 23,647 housing units, with 61.1 percent built before 1960 and 77.8 percent before 1980. The City's own Housing Element says half of all homes went up between 1940 and 1959 and that housing over 30 years old typically needs major rehabilitation such as a new roof. Rain is modest, 11.77 inches a year at NOAA's Hawthorne Municipal Airport station about 6.4 miles away, but roughly 81 percent of it falls from December through March, so the first big storm of the season is when a tired valley or a dry vent boot gives itself away.
On a Compton roof, MDG Builders (CSLB #1040337) acts as the general contractor: we write the scope, file with Building and Safety and keep the calendar, and a licensed C-39 roofing subcontractor does the tear-off and the new covering. Our roofing page holds the sourced price table. The same City rules shape fence work, house painting and kitchen remodeling, and all of them are gathered on the Compton overview.

What Compton's re-roof guidelines and exemption list say about roofs
Where roofing permits come from in Compton: City of Compton Building and Safety Department.
- Form B-017 (Re-Roof Inspection Guidelines) requires three inspections for a re-roof: a pre-roofing tear-off inspection before sheathing is covered, a sheathing inspection, and a final. It requires at least a Class B roof covering, attic ventilation at a 1 to 150 ratio, cool roofing rating verification, a smoke alarm and carbon monoxide alarm check inside the home, and a ladder at least 36 inches above the roof line. The Municipal Code's exemption list in Chapter 15 does not mention roofing.
- Form B-017 limits overlays to two composition roof coverings and a total roof covering weight of 7 pounds per square foot without an engineering analysis, sets minimum slopes of 2 in 12 for composition, 3 in 12 for wood shake and 4 in 12 for interlocking concrete tile, requires solid sheathing for most coverings, says partial roofing is not accepted (colors and textures must be consistent with accessory structures), says structures without permits cannot be roofed over, and says skylights need their own building permits.
Sources for these rules
Does roof repair in Compton need a permit, or is a small patch exempt?
Nothing in Compton's written rules says a re-roof is exempt, and nothing says it is not. The amended exemption list in Chapter 15 of the Municipal Code covers sheds up to 120 square feet, fences, low retaining walls, driveways, painting and cabinets, but it never mentions roofing. We found no City page that answers the permit question in plain words.
What the City does publish is Form B-017, its Re-Roof Inspection Guidelines, and a form like that only makes sense for permitted work. Our reading is to treat any replacement as permitted. For a small repair, such as resetting a few shingles, one call to Building and Safety at (310) 605-5509 settles it. The department page lists Monday through Thursday hours of 7:00 a.m. to 6:00 p.m.
Who applies is settled on paper too. Form B-020 says a contractor brings a state license card, photo ID, workers' compensation proof and a current City of Compton business license, and signs the application in person or sends an agent with a notarized authorization. Permits and inspections run through the Citizen Serve portal, and only a contractor or broker with an active City business license can log in.
Write down the name of the person at the counter and the date you asked, and keep it in the job file.
What happens at the three City inspections during a Compton re-roof?
Form B-017 lists three stops. The first is a pre-roofing tear-off inspection, held after the old covering is stripped and before any sheathing is covered. The second is a sheathing inspection, and the third is the final. The inspector also expects a ladder that reaches at least 36 inches above the roof line, so the crew has to leave one in place on inspection day.
The form adds checks that catch owners off guard. The inspector verifies the cool roofing rating of the new product, confirms attic ventilation at a ratio of 1 to 150 and looks at the smoke alarm and carbon monoxide alarm inside the house. Because the alarm check is part of the inspection list, test both the week before.
Build the schedule around those stops. A crew that strips and papers the whole roof in one afternoon leaves the inspector nothing to approve, so ask when each inspection will be requested and who will be on the roof when the inspector arrives.
- Tear-off inspection: before the sheathing is covered
- Sheathing inspection: before underlayment and covering go on
- Final inspection: ladder in place, alarms working, ventilation and cool roof rating on hand
What does Compton allow for roof replacement: coverings, layers and slopes?
Under Form B-017, a Compton re-roof needs at least a Class B roof covering. Overlays are limited to two composition roof coverings, and the total covering weight may not pass 7 pounds per square foot without an engineering analysis. Minimum slopes are 2 in 12 for composition, 3 in 12 for wood shake and 4 in 12 for interlocking concrete tile, and most coverings need solid sheathing.
Partial roofing is not accepted, and the form asks for colors and textures that are consistent with accessory structures, so plan the garage and the house together. Skylights are separate: each needs its own building permit, and if you want one replaced while the roof is open, say so when the permit is requested.
The edition question is worth one phone call. Chapter 15 adopts the 2019 California codes, while the City's plan check form cites 2022 editions and a newer ADU form cites 2025, so ask which one governs your permit.
Can you re-roof a garage conversion or backyard room that never had a permit?
Form B-017 says structures without permits cannot be roofed over, and in Compton that rule meets the City's presale requirement. Before a residential building is sold or exchanged, the City requires a Report of Residential Building Records under Municipal Code Sections 14-2.3 and 14-2.4. Form B-004 says the inspection covers all interior and exterior space, including rooms, closets, the garage and sheds.
So an enclosed patio, a converted garage or a back room added decades ago can stall a roof job and a sale together. The usual fixes are a permit that legalizes the work or, at sale, an AS-IS release signed and notarized by the buyer. The 2022 form lists the single-family inspection fee at $129, a release at $75 and the report as valid for six months, and fees may have changed since.
A fair roofing estimate starts with a walk around the property that lists any room or outbuilding that looks added, before the first bundle of shingles is ordered.
What are 1950s Compton roofs hiding under the shingles?
Half of Compton's homes date from 1940 to 1959, so a typical roof has been replaced at least once and may still sit on its original deck. Look at the places where the roof changes direction or something pokes through it: valleys, plumbing vent boots, chimney and wall flashing, and the ridge. A ceiling stain often starts somewhere else along the underlayment, so trace a leak from the attic before a patch is priced.
Old decks are the pricing wildcard. Boards laid with gaps between them do not suit most coverings, since B-017 asks for solid sheathing, so new plywood may go over the old boards. Rot found at tear-off is the other surprise, and the City's tear-off inspection exists to look at exactly that.
The Housing Element calls rehabilitation of aging homes a priority and names roofs, foundations and plumbing as the usual major work after 30 years, which fits the age table. The covering is the visible problem, but the deck, the flashing and the ventilation decide how long the next roof lasts.
Does a Compton roof replacement involve cool roof rules, a fire rating or solar panels?
Compton's climate is mild but sunny. NOAA's 1991 to 2020 normals for the Hawthorne station show an average August high of 78.7 F, about 9 days a year at or above 90 F and 63 days at or above 80 F. The City's plan check form lists Climate Zone 8, Seismic Zone D and a 110 mph wind design with Exposure C. B-017 asks for cool roofing rating verification, but we did not read the specific rule, so this page prints no reflectance number. Ask your roofer for the product's Cool Roof Rating Council label and confirm the requirement at the counter.
Solar changes the order of work. Panels usually come off and go back on, and Angi's Los Angeles page prices that at $500 to $1,000. The re-roof form does not mention solar, so ask whether a reset needs its own permit, and book the solar installer before the tear-off date.
Wildfire is not the driver here. Every one of the 42 sample points we checked in CAL FIRE's Local Responsibility Area layer came back Non-Wildland, and the Housing Element calls Compton an urban environment with little wildfire danger. A sample is not a parcel map, and we found no Class A rule for Compton re-roofs, so Class B is the minimum we can cite.
How much does roof replacement cost in Compton, and how do you hire a roofing company?
No Compton price survey or building permit fee schedule turned up, so this page shows no Compton price and no permit fee. The nearest sourced numbers are for Los Angeles. Angi's July 2026 Los Angeles page lists asphalt at $4 to $12 per square foot, tile at $7 to $15 and metal at $7 to $16, with tear-off at $1,000 to $3,000. Remodeling magazine's 2025 Cost vs. Value report prices a reference Los Angeles roof at $36,417 in asphalt and $62,069 in metal, and it does not publish that roof's size.
Roofing is CSLB class C-39. Ask for the license number, the current Compton business license, workers' compensation proof and a signed contract. California Business and Professions Code 7159 caps a down payment at $1,000 or 10 percent, whichever is less, and gives you three business days to cancel. On an MDG job you can ask for the roofing subcontractor's license and certificate of insurance, and our note on how general contractors use subcontractors explains who answers for what.
- Tear-off and disposal as its own line
- New plywood over spaced boards, priced per sheet
- Solar panel removal and reset
- Any skylight, which needs its own permit

Where the roof numbers come from
No independent price survey covers Compton, so the sourced Los Angeles figures and their method are in the table on our roofing price page, and the California roof replacement cost guide explains why Angi and Cost vs. Value differ so much. Our guide to checking a contractor's license shows what the CSLB record contains. Fence and paint rules often come next, and the Compton versions are on the fencing page and the painting page.
| 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. |
Compton roofing questions, answered
How much does roof replacement cost in Compton, California?
No Compton price survey turned up, so use the Los Angeles ranges. Angi's July 2026 data gives $4 to $12 per square foot for asphalt, $7 to $15 for tile and $7 to $16 for metal, plus tear-off at $1,000 to $3,000. Roof area drives the total, and a measured written proposal is the real price.
Do I need a permit for roof repair in Compton?
Ask first for a small repair, and treat a full replacement as permitted. Compton's exemption list in Chapter 15 never mentions roofing, and the City publishes Form B-017 with three required inspections for a re-roof. Building and Safety answers permit questions at (310) 605-5509, Monday through Thursday.
How many inspections does a Compton re-roof get?
Three. Form B-017 lists a tear-off inspection before sheathing is covered, a sheathing inspection and a final. The inspector also checks the cool roofing rating, attic ventilation at 1 to 150, the smoke and carbon monoxide alarms inside the house and a ladder that rises 36 inches above the roof line.
How many layers of roofing are allowed in Compton?
Up to two composition layers, and only if the total weight stays at or under 7 pounds per square foot without engineering. Form B-017 sets those overlay limits. It also says partial roofing is not accepted and that structures without permits cannot be roofed over, so a tear-off is the safer path on an old roof.
What is the 25 percent rule for roof repairs?
The Compton documents we read contain no 25 percent rule for roofs. Contractor pages that quote one rarely name a section. What Form B-017 does say is that partial roofing is not accepted and that overlays are capped at two composition coverings, so ask the counter how your repair would be treated.
Should I repair or replace my roof in Compton?
Repair when damage is local and the deck is sound, and replace when the deck is soft or leaks keep appearing in several places. Ask any roofer to photograph the attic and the flashing before quoting. Keep in mind that Compton does not accept partial roofing, so a large repair can turn into a replacement.
Does a Compton roof have to be Class A?
No Class A rule turned up for Compton re-roofs. Form B-017 requires at least a Class B covering. CAL FIRE's Local Responsibility Area layer showed Non-Wildland at every point we sampled, but a sample is not a parcel map, so confirm your address with Building and Safety.
How do I check a roofing contractor in Compton?
Look up the C-39 roofing license on the CSLB site, then ask for the current City of Compton business license, workers' compensation proof and a signed contract under Business and Professions Code 7159. The City's permit form requires a state license card, photo ID and these documents from any contractor who applies.
What is the best time of year for roof replacement in Compton?
Dry months make a tear-off easier to protect, though we found no sourced price pattern by month. NOAA's normals for the Hawthorne station show 11.77 inches of rain a year, with about 81 percent falling from December through March, so a summer or early fall start leaves the most room for delays.
Do solar panels change a Compton roof replacement?
Yes, because panels usually come off and go back on. Angi prices that at $500 to $1,000 for Los Angeles. The City's re-roof form does not discuss solar, so ask whether the reset needs its own permit and book the solar installer before the tear-off date.
