Observation: Aluminum or vinyl lap siding courses are not parallel with eaves or wall openings.
Performance Standard: Any piece of aluminum or vinyl lap siding more than 1/2 inch off parallel with the bottom course or more than 1/4 inch off parallel with contiguous courses is not acceptable, unless the owner and the remodeler have previously agreed to disregard the performance standard to match a preexisting structural condition.
Corrective Measure: The remodeler will reinstall siding to comply with the performance standard and replace any siding damaged during removal with new siding.
