Installing house wrap is one of the most important steps in protecting a building from moisture and air intrusion. But even experienced builders can make errors that compromise its effectiveness. Small installation mistakes can lead to costly repairs, reduced energy efficiency, and long-term damage.
In this post, we’ll break down the top three house wrap installation mistakes and share how to avoid them. Whether you’re a contractor, builder, or serious DIYer, these tips will help you install house wrap correctly for maximum performance. Plus, we’ll show how ALTA® 360 drainable house wrap makes the process easier and more reliable.
Mistake #1: Not Overlapping Seams Correctly
One of the most common house wrap problems is improper seam overlap. Without the right overlap, water can sneak behind the wrap and damage the sheathing. A short or incorrectly placed overlap often allows wind-driven rain to get past the barrier.
How to Avoid It:
Install house wrap in a “shingle style,” meaning each upper layer overlaps the lower layer by at least 6 inches horizontally and 12 inches vertically. This directs water down and away from the structure. ALTA® 360’s drainable design channels water efficiently, giving you an extra layer of protection.
Mistake #2: Skipping the Flashing Around Openings
Windows, doors, and vents are the weak points in any wall system. Skipping flashing or relying solely on caulk creates gaps where water can enter.
How to Avoid It:
Always follow the correct flashing sequence: sill flashing first, then jambs, then head flashing. Use flashing tape that adheres well to the wrap and the substrate. ALTA® 360 integrates seamlessly with flashing systems, ensuring these high-risk areas remain watertight.
Mistake #3: Over- or Under-Fastening the Wrap
Too few fasteners allow the wrap to loosen or tear in the wind, while too many create unnecessary holes that can compromise the barrier.
How to Avoid It:
Follow manufacturer instructions for fastener spacing—typically every 12–18 inches along studs. Use cap nails or cap staples to distribute pressure and prevent tearing. ALTA® 360’s strong, tear-resistant construction holds up during installation, even in challenging weather.
Why ALTA® 360 Helps Prevent These Mistakes
Choosing the right house wrap makes a big difference. ALTA® 360 isn’t just a moisture barrier—it’s a drainable house wrap designed to manage water effectively, hold up during installation, and integrate easily with flashing systems. Its performance features help reduce the risk of these common installation errors, saving time and costly rework.
