Relevant repair topics for the commercial building types around San Bernardino and Ontario include these roof systems and details. The correct method depends on the actual roof material and extent of damage, rather than the county alone.
Flat commercial roofs need careful leak tracing because water can travel beneath the surface before appearing indoors. Drainage, seams, flashings and penetrations should be evaluated together.

Open seams and compromised laps can let water enter a commercial roof system. The appropriate repair depends on whether the roof uses welded, bonded, mechanically fastened or asphaltic joints.
Inspection focus: Identify the exact seam system, separation extent and moisture conditions before repair.
HVAC curbs, duct penetrations and service activity can compromise roofing details. Water may enter around the unit even when the membrane field is sound.
Inspection focus: Evaluate curbs, counterflashings, service penetrations and nearby traffic damage.
Expansion joints accommodate structural movement. Leaks may occur when flexible covers, seals or transitions deteriorate or are incorrectly repaired.
