Is House Wrap Necessary When Installing Siding?

During roof maintenance, repairs, and replacement jobs, roofers will often put down the underlayment, a water-resistant barrier, first to make sure that the roof deck is 100% protected against water penetration. The roof surface itself may do the bulk of the work, but the underlayment is there to catch any potential leaks that might slip through the shingles.

House wrapping works in a similar fashion to roofing underlayment, but for siding instead. There are contractors who may suggest that you can forego using house wraps when you’re replacing your siding. Still, most installers will say that it’s a vital part of your siding system. Let our experts at V. Nanfito Roofing & Siding, Inc. show you why you should always use house wrap in your exterior remodeling projects.

What Is House Wrap for?

While most siding boards used in home improvement are made to be weather-resistant, they are not 100% waterproof. Wind-driven rain, in particular, can seep in between the panels and penetrate the vulnerable wall cavity. House wrapping prevents this from happening. House wrap can be made from a special kind of fabric, paper, or board material that keeps water out but remains permeable enough to allow water vapor to escape outside.

Is It Essential to Use House Wrap

In a nutshell, the answer is yes. House wrap is not just water-proof. Moisture doesn’t just come from the outdoors. Indoor sources can also put a lot of moisture into the wall cavity. This is why it’s important that house wraps are only water-impermeable from the outside. If water cannot penetrate from the inside, then your drywall can still be prone to moisture produced in your home.

Professional Installation

Talk to your general contractor about installing the right type of house wrap before placing the siding panels in place. House wrap should also be used when replacing windows and doors to prevent further moisture problems from entering using these avenues.
