Thiena Corporation

Thiena Corporation operates out of Corona in Riverside County and carries CSLB license #902585, classification A — General Engineering, B General Building, C39 Roofing. At the time this listing was compiled, the license was active with no suspension on record.

Roofing contractors hold the C-39 classification, which covers the roof covering itself plus the substrate preparation and waterproofing layers underneath it.

Working in the Inland Empire: Expansive clay soils are common across the inland valleys, and they move enough with the seasons to matter for foundations, flatwork and anything tied to them.

Before you hire any roofing contractor: Get the tear-off scope in writing. Whether the old layers come off or a new roof goes over them changes both the price and how long the result lasts.

License status can change at any time. Confirm license #902585 is current, and check bond and workers’ compensation coverage, using the CSLB license lookup before signing a contract or paying a deposit.
