Tear in Building Paper

On a recent pre-drywall inspection in Las Vegas, we found a tear in the building paper behind the exterior wall. It may look like a small defect, but this layer plays an important role in helping protect the wall assembly from water intrusion.

When there is damage or an opening in the building paper, water can potentially find its way into the wall cavity. That's why we recommend addressing issues like this while the exterior wall is still accessible.

What This Means For You

Building paper is part of the home's weather-resistant barrier. Its job is to help prevent water that gets behind the exterior cladding from reaching the framing and other components inside the wall.

A tear doesn't automatically mean water is entering the home, but it does create a potential path for moisture to get where it shouldn't. Once drywall and other finishes are installed, identifying exactly where water is entering can become much more difficult.

Why It Matters

Water intrusion isn't always immediately visible. Moisture that gets into a wall cavity can remain hidden behind the finished wall and potentially contribute to deterioration, staining, or other moisture-related problems over time.

This is especially important during new construction because the building paper is part of a larger system designed to manage water around the exterior of the home. One damaged section may not cause a problem by itself, but it should still be properly repaired so the system can perform as intended.

The good news is that this is much easier to address before the walls are closed up.

What We Typically Recommend

We recommend having the builder repair the damaged building paper and verify that the weather-resistant barrier is properly sealed in the affected area.

We also recommend asking the builder to provide photos documenting the completed repair. This gives you a record that the issue was addressed before the wall was covered.

Main Takeaway for Las Vegas Home Buyers

A tear in building paper might not look like a major defect, but it's exactly the type of issue that can be difficult to inspect or repair once the walls are finished.

A pre-drywall inspection gives you an opportunity to catch construction defects while the components are still visible and accessible.

If you're building a new home in Las Vegas, a pre-drywall inspection can help identify issues before they're hidden behind drywall, insulation, and finished surfaces.
