VINYL SIDING WARP
Description:
Warping or buckling of vinyl siding panels that have been repainted

Cause(s):
Most likely cause is that vinyl siding was repainted with a darker color paint than the original color
Dark paint tends to absorb the heat of the sun, transferring it to the substrate
When vinyl siding expands dramatically, it is not able to contract to its original dimensions

Solution(s):
Paint vinyl siding in a shade no darker than the original
