Signs that vinyl siding is in need of replacing contain:
Broken or warped panels:Siding panels that are no longer flat against your home are not doing their job protecting you from the components. Siding can bend and break due to flying debris, like a downed tree limb or a hard hit from a baseball, or due to high winds getting in under the seams, due to age. Cracked vinyl siding panels and bent can not be reformed, so whether the problem is prevalent or is in one place, you will need to contact a contractor to discuss siding replacing.
Mold or mildew on siding:If you see mildew or mold growing on the exterior of your siding, you may have a moisture problem in that region of the building. It is not impossible that warped or loose siding is letting an excessive amount of wetness collect, and this scenario can have effects beyond the damage due to mold growing.
