Old cracked or broken siding or siding falling off can allow water to get behind your siding and can lead to rotten sheathing and that water can work its way into your walls and can create even bigger issues including mold and rotten framing, which can effect the structural integrity of your house.

Whichever type of siding you choose they all have an important thing in common and that is to protect your house from the elements.

We always install housewrap behind siding as a second barrier.
