Re-Roofing an Occupied Commercial Building

How an occupied building is phased

• The roof is divided into sections sized so each one is watertight before the crew leaves that day
• Material is staged to minimise crane and forklift time in tenant parking
• Noise-sensitive areas — medical suites, call centres, classrooms — scheduled around their hours
• Tenant notice issued in advance, with the actual sequence and dates, not a vague window
• Interior protection where equipment sits directly beneath work areas

Permits and inspection

A commercial re-roof needs a permit and an inspection whether the building sits inside Sacramento city limits or anywhere else in the county. The licensed contractor pulls that permit under their own name, and the inspector confirms insulation and cool-roof requirements.

Leaving the permit out of a bid doesn't lower the price. It leaves the bid unfinished, and an unpermitted roof turns into a disclosure issue as soon as the building is sold or refinanced.

What you should receive at closeout

• The manufacturer warranty, registered and in the building's name
• The signed-off permit
• As-built details for every curb, drain and penetration
• Product data and CRRC rating documentation for the cool-roof compliance record
• Photographs of the deck and substrate before the new system went on
• The maintenance schedule the warranty requires, and who is responsible for it

Who holds the contract

You sign with Cutting Edge General Contracting, licensed by CSLB under #1007180 as a General Building (B) contractor. The roofing itself goes on under subcontract by a licensed C-39 roofer, which §7057(b) of the California Business and Professions Code permits.

For an owner that means one contract, one insurance certificate to collect, and one party responsible when something needs revisiting.
