East Contra Costa County
Roof Repair & Replacement in Antioch, CA
Antioch is the largest city in East Contra Costa, with homes built over many decades. That range means roofing needs vary widely, from repairs on newer roofs to full replacements on roofs reaching the end of their life.
Permits in Antioch: re-roof and solar
The City of Antioch states that a re-roof permit is required, and that removing and reinstalling solar panels needs a separate permit (City of Antioch). If your home has solar, confirm who pulls each permit (the roofer, the solar company, or both) and that both are in writing.
Older roofs: know what's on top
With a wide spread of home ages, some Antioch roofs have more than one layer of shingles or are near the end of their expected life. InterNACHI lists architectural shingles at roughly 30 years and 3-tab at about 20 (InterNACHI). Ask the roofer how many layers are coming off, since tear-off is a meaningful part of the price.
Replacing more than half a roof within a year triggers California's roof-wide fire-rating requirement (Health & Safety Code §13132.7), which is one reason large repairs on old roofs sometimes become full replacements. Repair or replace?
