Roofing felt may not be the star of the show when it comes to your home’s roofing system, but it play an important role in protecting your home from the elements. As a crucial component installed beneath the shingles or other roofing materials, roofing felt acts as a barrier against moisture infiltration, ensuring the structural integrity and longevity of your roof. Because of this, you’ll need to know how to best take care of it and when to get it replaced. Let’s talk about roofing felt and when it may be time for inspection and replacement.

What is Roofing Felt? 

Roofing felt, also known as underlayment or tar paper, may not be the most glamorous aspect of your roof, but it plays a crucial role in protecting your home from the elements. Essentially, this thin layer is a waterproofing material installed beneath the shingles or other roofing materials to provide an additional layer of protection against water infiltration.

Why is it So Important?

This layer has several important functions in your roofing system. Firstly, it acts as a barrier against water, preventing moisture from seeping into the underlying structure of your roof and causing damage. It also helps to smooth out any irregularities in the roof deck, providing a flat surface for the installation of shingles or other roofing materials. Not only that, but it provides an extra layer of insulation, helping to improve the energy efficiency of your home.

Inspection and Replacement Frequency

While roofing felt is designed to be durable, it is not invincible. Over time, exposure to the elements can cause roofing felt to deteriorate, leading to potential issues such as leaks and water damage. Because of this, it’s important to have it inspected regularly by a professional roofing contractor. Ideally, you should have your roof inspected at least once a year, or more frequently if you live in an area prone to severe weather conditions such as heavy rainfall or high winds.

Signs It’s Time for a Replacement

There are several telltale signs that your roofing felt may need to be replaced. These include:

  1. Visible Damage: Look for signs of wear and tear, such as tears, cracks, or holes in the felt.
  2. Water Stains: Water stains on your ceiling or walls could indicate that water is penetrating through the roofing felt and causing damage.
  3. Mold or Mildew: Excessive moisture trapped beneath the roofing felt can lead to the growth of mold or mildew, which can pose health risks and indicate a potential roofing issue.
  4. Curling or Buckling: If the felt appears to be curling or buckling, it may be a sign that it has reached the end of its lifespan and needs to be replaced.
