    The City of Pasadena has adopted the 2010 California Building Code (CBC) and 2010 California Residential Building Code (CRC) and has made few amendements to some section which includes Roofing and Re-roofing requiremetns as a building standard (see Pasadena Municipal Code Section 14.04.110, 14.04.115, and 14.04.315).

    Built-up roofs must comply with the requirements as set forth in the codes. Rotting is common and may not adequately provide support for the new roof barrier.  Roof sheathing inspeciton is required before covering.  A final inspection is also required.

    Roofing with any tile weighing more than six pounds per square foot (6PSF) will require engineering calculations addressing the additional loads imposed upon the roof structure. The engineer must also note that the entire structure is adequate to sustain the additional loads, regardless if the original is torn off or not.

    Roofs requiring engineering calculations shall have submitted with calculations a dimension roof plan. An inspection of the roof is required (regardless if structural modifications are necessary) at a time the roofing material is torn off and before the solid sheathing is applied.

    When a layer or entire of roofing material is removed, plywood is replaced, or new plywood installed, nailing shall be inspected first before covering. If plywood is added over space sheathing, nailing inspection is required before installing any covering. When re-roofing over an exisiting roof, an inspection is required before new roofing material is installed.  A final inspection is always required.

    All roof sheating and roof final inspections shall require a ladder; contractor to supply ladder.  According to adoptted codes, smoke detectors and carbon monoxide dector alarms may be required see CBC Section 420.4.2 and CRC Section R314 and R315.
