Lap siding (wood, hardboard, vinyl, etc.) is not installed on a straight line

Acceptable Performance/Condition

Lap siding shall be installed with individual pieces in general, visible parallel alignment.


One-Year  Work and Materials
Defects in materials, work or design supplied by the homeowner are excluded from the warranty.


Lap siding that does not meet the acceptable condition shall be repaired.


With any type of siding or cladding such as lap siding that requires repetitive parallel alignment from one course to the next, the installer must make minor adjustments to keep the entire elevation in general alignment. Adjustments of this nature are normal. Wavy-edged siding is more tolerant of adjustments while maintaining an acceptable appearance.
