You cannot use roofing paper for house wrap because they serve different purposes and have different properties. Roofing paper is made to go under shingles on your roof. House wrap is made to go under siding on your walls. Using the wrong material can let water in and damage your home. Let’s look at what makes them different and why this matters.
What Is Roofing Paper Made for?
Roofing paper goes on top of your roof deck, right under your shingles. It stops water from getting into the wood below. The paper is thick and waterproof on one side.
Roofing paper is not meant to move or stretch. It breaks down in sunlight and wind. Most roofing paper lasts only 3 to 7 years before it falls apart.

What Is House Wrap Made for?
House wrap goes on your walls under the siding. It lets your house breathe while stopping liquid water. Good house wrap stops rain but lets air and water vapor escape.
House wrap is stretchy and flexible. It can bend around corners and obstacles. It lasts 30 years or more without breaking down.
According to industry data, the average roof lifespan is between 25 to 50 years, while roofing paper alone fails in just 3 to 7 years on its own.
Why the Wrong Material Causes Problems
Roofing paper on your walls will tear and rip. It cannot handle the movement and flexing that happens on vertical surfaces. Water will pool and seep through the holes.
House wrap on your roof under shingles will fail fast. Shingles get hotter than walls. The heat breaks down house wrap quickly. Moisture gets trapped, and rot starts.
According to RubyHome, leaking is the top reason homeowners replace roofs, affecting 33% of homeowners. Using the wrong materials only makes leaks worse and more expensive to fix.
Right Materials for Each Job
| Location | Right Material | Why It Works |
|---|---|---|
| Under Roof Shingles | Roofing Paper or Ice Shield | Handles heat and stops water |
| Under Wall Siding | House Wrap (like Tyvek) | Breathes and stretches |
| Roof Decking | OSB or Plywood | Stays strong and dry |
Using roofing paper as house wrap will fail. Your house will leak, and water damage will cost thousands to repair. Stick with house wrap for walls and roofing paper for roofs. According to This Old House, average roof replacement costs range from $9,858 to $41,822, and most of that cost comes from fixing water damage from bad materials. Use the right material from the start to save money later.
