Vinyl
Siding Warp: Warping or buckling of vinyl siding
panels that have been repainted.
Possible Cause:
Most likely cause is that vinyl siding was repainted with
a darker color paint than the original color. Dark paint
tends to absorb the beat of the sun, transferring it to
the substrate. When vinyl siding expands dramatically, it
is not able to contract to its original dimensions.
Solution:
Paint vinyl siding in a shade no darker than the original.
Whites, off-whites, pastels and other very light colors
are good choices. Top quality acrylic latex paint is the
best type of paint to use on vinyl siding, because the
superior flexibility of the paint film enables it to
withstand the stress of expansion and contraction cycles
caused by outdoor temperature changes.
Siding that has warped or buckled should be assessed by a
siding or home repair contractor to determine the best
remedy. The siding may have to be replaced.
