Published national guides put minor roof repairs commonly between about $300 and $1,500, with the failed detail deciding the number: flashing, a valley, or a small section. Full replacement is priced from the written scope after measurement. Northridge's variables are heat and history: Valley sun embrittles the vent boots and seals years before the field fails, and the earthquake era stock carries chimney and flashing work that has to be read on its own merits. Insurance commonly covers sudden wind and storm damage, subject to deductible, and does not cover a roof that wore out. The itemized written estimate is the number that matters.
Honest numbers first. Published national guides put a typical roof repair between about $300 and $1,500 for minor work, with larger section repairs running higher, and full replacement priced by the measured scope. In Northridge the detail decides the band before size does: composition shingle over felt, the low slope patio and addition sections on the ranch stock, and the earthquake era chimney and flashing work are three different jobs wearing one name. Nobody honest quotes a firm total by phone; the number is built from a roof walk and a written estimate.
| Job | Typical range | What moves it |
|---|---|---|
| Minor repair (flashing, vent, small section) | $300 to $1,500 | The band most single detail repairs land in, per published national guides. |
| Vent boot and seal renewal set | Priced per detail | Valley sun ages boots and seals first; renewed in materials rated for the exposure. |
| Low slope or flat section repair | Priced by the section | Ponding correction decides the scope; coating over standing water is not a repair. |
| Emergency tarping | Priced per visit | A bridge to the permanent repair, documented for the claim in the same visit. |
| Full roof replacement | Priced from the written scope | Measured on the roof, with underlayment, flashing, and attic ventilation named line by line. |
Ranges are published guide figures, not a quote for your home. Your estimate is written after a roof walk and should name the covering, underlayment, and flashing it includes.
Standard deductibles commonly run $500 to $2,500. Against a minor repair, doing the deductible math first can save a pointless claim; against wind damage across a whole slope, the claim is usually the right call. Sudden storm damage is the covered case; a roof that wore out in the Valley sun is maintenance, and the scope should say which one yours is before you file.
