Can I use roofing felt as house wrap

Many homeowners and builders always look for ways to save money and use alternative materials in construction projects. One question often arises is whether roofing felt can be used as a substitute for house wrap. In this blog post, we will explore the differences between roofing felt and house wrap and whether roofing felt can be used as an alternative.

What is Roofing Felt?

Roofing felt, also known as tar paper, is a type of waterproof material used in roofing projects. It is made of layers of fiberglass or other synthetic fibers that are saturated with asphalt or another waterproofing agent. Roofing felt protects the roof deck from water damage and provides a base for roofing shingles or other roofing materials.

What is House Wrap?

House wrap, also known as building wrap, is a moisture-resistant and breathable material used to protect the exterior walls of a house from water and air infiltration. It is usually made of a synthetic material such as polypropylene or polyethylene, and it is installed over the sheathing of a house before the siding is applied. House wrap is designed to allow water vapor to escape from the walls of the house while at the same time preventing water from entering the walls.

Can Roofing Felt be Used as House Wrap?

The short answer is no; roofing felt cannot be used as house wrap. At the same time, both materials are designed to protect against water damage but have different properties and functions.

Roofing felt is intended to be used on the roof of a house, where it is exposed to the elements and must withstand extreme temperatures, wind, and rain. It is not designed to be used on the walls of a house, where it would be exposed to less extreme conditions and would not provide the same level of protection as house wrap.

House wrap, on the other hand, is specifically designed to be used on the walls of a house. It is lightweight, breathable, and flexible, which makes it easy to install and allows it to conform to the contours of the walls. House wrap also has a higher water and air infiltration resistance than roofing felt.

Conclusion

In conclusion, roofing felt cannot be used as a substitute for house wrap. While both materials are designed to protect against water damage, they have different properties and functions and are intended for use in different house parts. To ensure the best protection against water and air infiltration, it is important to use the correct material for the job.
