While the installation of fiber cement siding, an additional layer consisting of flashing must be installed wherever there is a joint between two siding panels i.e., where they meet.
This flashing will go up to the top of the wrap. The layering approach will always be the best. For waterproofing, the home installation of water-resistant layers is very much crucial.

Is Vinyl Waterproof?
Is vinyl flooring waterproof? Yes, and for this reason, vinyl flooring is incredibly popular! Vinyl plank flooring is the perfect flooring solution for busy households, basements, bathrooms and even kitchens. But just because vinyl flooring is waterproof, doesn’t mean it will survive flooding.
Water Dripping Down Siding
Water under siding can often be traced back to bad caulking around window and door frames. Installing new siding over original siding materials can allow damp to seep under outer edges. The runoff from a leaky roof trickles down a home’s exterior and seeps between siding and wood sheathing.
What Happens If Water Gets Behind Siding?
When moisture penetrates the boards, vinyl siding traps the water that accumulates behind it. Unfortunately, this moisture trap can lead to mold growth, rot, and structural damage, especially when proper sheathing, caulking, and waterproof barriers aren’t installed.
Waterproofing House Cost
While basement waterproofing costs between $5 and $10 per square foot, damp proofing basements comes in at $3 to $6 per square foot on average.
