Thor Construction

Thor Construction operates out of Rialto in San Bernardino County and carries CSLB license #700514, classification B — General Building, C39 Roofing. License status at the time of compiling this listing: active, with no suspension recorded.

The C-39 classification is what California requires for roof covering work: tear-offs, re-roofs, repairs, and the underlayment, flashing and edge detail that do most of the real waterproofing.

Working in the Inland Empire: Inland Empire summers are long and hot, and Santa Ana wind events each autumn put real load on anything attached to the outside of a building.

Before you hire any roofing contractor: Ask what underlayment is being used and how the flashing at valleys, walls and penetrations will be handled — that detail is where most roof leaks actually start, not the tile or shingle.

License status can change at any time. Confirm license #700514 is current, and check bond and workers’ compensation coverage, using the CSLB license lookup before signing a contract or paying a deposit.
