If you're interested in installing shingles on a shed, you might be asking yourself: Do I need tar paper under shingles on a shed? Deciding whether to use tar paper under shingles on a shed is a common dilemma faced by many DIY enthusiasts and builders. 

In this article, we delve into the importance of tar paper, also known as roofing felt, as an additional layer of protection for your shed's roof. While it's not always a requirement, incorporating tar paper can significantly enhance the durability and moisture resistance of your roof.

As experts in shed-building, we've seen firsthand the benefits this extra step can provide, and we're here to share those insights with you, ensuring your shed stands strong against the elements.

Do I Need Tar Paper Under Shingles on a Shed?

When it comes to the question of whether you need tar paper under shingles on a shed, the short answer is yes, it's highly recommended.

Tar paper, or roofing felt, acts as a crucial barrier, offering an additional layer of protection for your shed's wooden structure beneath the shingles. So, we would highly recommend learning how to felt a shed roof before installing the shingles.

The Purpose of Tar Paper

Tar paper serves several critical functions that shouldn't be overlooked:

  • Waterproofing: In our experience, it acts as a secondary barrier against moisture, ensuring that any water sneaking past your shingles doesn't compromise the wood beneath.
  • Protection During Construction: It safeguards your roof from the elements until the shingle installation is complete.
  • Enhanced Durability: By preventing moisture from reaching the wood, tar paper extends the overall lifespan of your roof.

Weighing the Necessity

While tar paper might not be mandatory for every shed, we strongly advocate for its use. Here's why:

  • Climate Considerations: After putting it to the test, we've found that in areas prone to heavy rain, snow, or high humidity, tar paper can significantly bolster your roof's defense against moisture.
  • Long-Term Protection: Considering the valuable tools and equipment often stored in sheds, the added durability that tar paper provides is a wise investment.
  • Peace Of Mind: The assurance of having that extra layer of protection is invaluable, especially when the weather turns foul.

Installation Tips

For those ready to take the plunge, here are some key installation tips to ensure your tar paper serves its purpose effectively:

  1. Proper Overlap: Mimic the shingle effect by overlapping each strip of tar paper, directing water away from the roof.
  2. Secure Attachment: Use an appropriate amount of fasteners to keep the tar paper in place without compromising its integrity.
  3. Preparation Is Key: A clean, smooth roof deck is crucial. Any protrusions or debris can tear the tar paper, reducing its effectiveness.
