Roofing in Simi Valley, by the numbers

Computed from our records · as of Jul 11, 2026

What do roofing jobs actually cost in Simi Valley?
We don’t yet have enough itemized residential roofing permits in Simi Valley to publish a reliable local cost range. Across California, the median filed residential roofing-permit amount is $14,000 - a real filed figure rather than a national estimate. As more Simi Valley permits come on record, we’ll show the local range here.
How many roofing companies in Simi Valley are actually licensed and verified?
Of the 1 company we track in Simi Valley, 1 has an active contractor license located in public records, 0 are registered business entities, and 1 operates from a commercial rather than residential address. California requires roofers to carry a C-39 roofing-contractor license from the Contractors State License Board (CSLB). A company not appearing with a license here isn’t proof it’s unlicensed - some jurisdictions don’t publish - so verify directly, and always confirm liability and workers’ comp insurance before work starts.
What should I know about roofing for Simi Valley's climate?
Roofing demand in Simi Valley is driven less by storms than by wildfire exposure, heat aging, and Title 24 cool-roof rules. Class A fire-rated assemblies and cool-roof-compliant materials are the priority in most jurisdictions. Of the 1 companies we track, 1 hold a manufacturer certification for these systems.
Which manufacturer certifications do Simi Valley roofers hold?
1 of the 1 roofers we track in Simi Valley hold at least one manufacturer certification (GAF, Owens Corning, CertainTeed, TAMKO, IKO, Malarkey). The most common here is Owens Corning, held by 1 company - versus 46% certified across California. Certification means the manufacturer vetted the contractor and lets them back your roof with stronger, longer material-and-labor warranties. Not required to install a roof, but a real signal of training and standing.
