Roofing Estimating Softwarefor San Diego Contractors
If you're bidding roofing in San Diego, the gap between a job that nets margin and one that doesn't usually comes down to underestimating waste factor for complex roofs — and how you handle wildfire risk in wui zones. Drop a plan set in, walk away for 10 minutes, come back to a priced bid you can defend.
What San Diego does to a roofing bid
Mild year-round, dry summers, wet winters, fire and earthquake risk. Temperatures swing 45°F - 85°F, rainfall runs 15-25 inches, and inspectors here are working off CRC + Title 24 Part 6. None of that shows up on a plan symbol legend — but it changes your fastener schedule, your waste factor, and whether the building department signs off on the rough.

Pulling permits in California: the license you actually need
California won't let you sign a roofing contract without a C-39 Roofing Contractor License, issued by the California Contractors State License Board (CSLB). Subbing under a licensed GC is one workaround, but on direct-to-owner jobs the homeowner can void the contract if you don't hold the card.

Stuff San Diego roofers ask before they sign up
Does this respect CA code, or do I have to re-cut every quantity?
Counts assume CRC + Title 24 Part 6 (Class A roof in WUI, solar PV mandate on new construction, R-15 wall continuous insulation). The takeoff doesn't pull a permit for you — that's still on whoever holds the C-39 Roofing Contractor License — but the assemblies match what CA inspectors look for.
How do you handle manually counting squares from blueprints takes hours?
The model reads the plan once, counts symbols against your assembly library, and surfaces the count for review. You override anything that looks off before it hits the quote. For residential work in San Diego, the typical correction is one or two assemblies — not redoing the whole thing.
What about wildfire risk in wui zones?
Class A fire rating required in many areas. Tile and metal popular for fire resistance. Cool roofs required in many climate zones. Solar panels now mandated on new construction.
Anything else specific to California?
California's CSLB issues the C-39 license specifically for roofing. All projects over $500 (labor + materials) require a licensed contractor. Title 24 energy compliance is required.
How much does a permit add to a roofing job around here?
