Each county page describes the local building stock, the climate stresses on flat roofs there, the permit offices that apply and the towns we reach. Pick a county below to see the figures for your area.
Which Southern California counties are on our service list?
Southern California includes 6 counties on our list, from Los Angeles and Orange on the coast to Riverside and San Bernardino in the Inland Empire.
Logistics buildings dominate the inland counties, while coastal counties mix tilt-up industrial parks, offices, medical buildings and retail centers. Salt air near the ocean and high summer heat inland age roofs in different ways.
- Los Angeles CountyExample: 120,000 sq ft distribution warehouse
- Orange CountyExample: 80,000 sq ft tilt-up industrial building
- Riverside CountyExample: 400,000 sq ft big-box distribution center
- San Bernardino CountyExample: 500,000 sq ft distribution center
- Ventura CountyExample: 60,000 sq ft light industrial building
- San Diego CountyExample: 100,000 sq ft industrial building
Which Central Coast counties do our crews reach?
Our crews reach 5 Central Coast counties, running from Santa Barbara north through San Luis Obispo, Monterey and San Benito to Santa Cruz.
Agriculture shapes the roof stock here: produce coolers, wineries, packing sheds and food plants sit beside downtown retail and campus buildings. Marine fog keeps many roofs damp for long stretches, which favors moisture scanning.
- Santa Barbara CountyExample: 50,000 sq ft commercial building
- San Luis Obispo CountyExample: 40,000 sq ft winery production building
- Monterey CountyExample: 120,000 sq ft produce cooling facility
- San Benito CountyExample: 60,000 sq ft agricultural processing building
- Santa Cruz CountyExample: 50,000 sq ft food processing plant
Which Central Valley counties are part of our coverage?
Our coverage includes 8 Central Valley counties along Highway 99 and Interstate 5, from Kern in the south to San Joaquin in the north.
Distribution centers along the freeways and processing plants for nuts, citrus, dairy and produce make up most of the large flat roofs. Summer heat above 100 degrees and tule fog in winter are the main stresses.
- Kern CountyExample: 600,000 sq ft distribution center
- Tulare CountyExample: 150,000 sq ft citrus packing house
- Kings CountyExample: 70,000 sq ft food processing plant
- Fresno CountyExample: 300,000 sq ft distribution center
- Madera CountyExample: 100,000 sq ft nut processing plant
- Merced CountyExample: 120,000 sq ft food processing plant
- Stanislaus CountyExample: 200,000 sq ft food processing plant
- San Joaquin CountyExample: 800,000 sq ft distribution center
How long does a roof scan take on a typical building in each region?
Our scan covers about 50,000 square feet an hour, so example buildings across the 3 regions range from about 1 hour to about 16 hours of scanning.
Roof sizes match the example building on each county page. Actual time depends on access, equipment density and roof sections.
Very large roofs are scanned across consecutive days, and the report still arrives within 48 hours of the final pass. How the scan works is covered on commercial roof inspections.
What does a maintenance program cost in different counties?
Program pricing uses the same 3 published tiers in every county: Monitor at $0.12 to $0.15, Protect at $0.22 to $0.25 and Manage at $0.40 to $0.45 per square foot per year.
| County | Example roof size | Tier | Example annual cost |
|---|---|---|---|
| San Joaquin County | 800,000 sq ft | Protect | $176,000 to $200,000 |
| Kern County | 600,000 sq ft | Protect | $132,000 to $150,000 |
| San Bernardino County | 500,000 sq ft | Protect | $110,000 to $125,000 |
| Fresno County | 300,000 sq ft | Protect | $66,000 to $75,000 |
| Los Angeles County | 120,000 sq ft | Protect | $26,400 to $30,000 |
| Santa Barbara County | 50,000 sq ft | Monitor | $6,000 to $7,500 |
Minimums are $1,500 for Monitor, $2,500 for Protect and $4,500 for Manage. Location does not change the rate; roof size and the tier you choose do. Full tier details are on the maintenance programs page.
How do we schedule work across 3 regions?

Receive the report
A licensed Professional Engineer signs the report, delivered within 48 hours.
