Old Underlayment: Why Does It Need Replacement?

There’s more to roof replacement than installing new shingles and nails. While not visible, the underlayment safeguards your home from leaks and water damage. It needs to be replaced like other old parts of the roofing system. Read on to learn why. 

Old Underlayment

The Importance of Underlayment

Underlayment is a secondary barrier that protects your indoor spaces from water intrusion. You’ll find it between the shingles and the decking. It’s usually made of asphalt-saturated felt and other synthetic materials. Over time, your roof’s underlayment can deteriorate due to age and exposure to the elements. Once damaged, you could experience leaks and other moisture-related problems. 

Why Does It Need to be Replaced? 

You can choose between an overlay and a tear-off when it’s time for a new roof. An overlay is when roofers install new materials over the old shingles. On the other hand, a tear-off involves removing the old components before securing the new ones. 

Experienced roofers will recommend the latter option since it offers longer-lasting and more aesthetically pleasing results. Tearing off the old materials allows professionals to assess the decking and address underlying issues. It also ensures the new underlayment and other components have a solid foundation. 

Moreover, technologies have evolved, and modern underlayments provide better protection against water, UV rays and physical damage. Upgrading to a new underlayment can strengthen your roof and prolong its lifespan. It can also help ensure your home meets current building codes, saving you from legal and insurance issues in the future.
