4 Reasons To Replace Old Roofing Underlayment During Roof Replacement

Are you considering replacing your current shingle roofing system? Then consider replacing the old underlayment that lies under the shingles as well. The underlayment, which may be made of wood, fiberglass, or polyester, acts as the second protective layer of your roof. Thus, if your roof shingles suffer damage and water seeps into your roof, the underlayment acts as a secondary barrier.

To ensure that your roof and home are fully protected from the elements, replace your underlayment as well as your roofing materials during a roof replacement. This is important for several reasons.

1. Underlying issues can be spotted and dealt with

Some roofers may place a new layer of underlayment over the old layer of underlayment. But make sure you avoid doing this with your roof, especially if your roof is very old. Removing the old layer of underlayment gives roofers a chance to inspect your roof for common problems like mold, fungus, and wood rot among other things.

Placing a new shingle roof without inspecting the area under your old underlayment could hide serious issues that compromise your roof's longevity.

2. Newer underlayment materials are superior

The quality of current underlayment materials is superior to the underlayment materials of old. In the past, asphalt-saturated felt underlayment was the most commonly used material for roof underlayment. If your roof is old, then the underlayment may be asphalt-saturated felt. You could replace it with a synthetic or rubberized asphalt underlayment, both of which are superior.

3. You can improve your home's fire-resistance rating

If you want to improve your home's fire-resistance rating, then you could choose a new underlayment with a superior fire-resistance rating. For instance, if your current underlayment only has a B rating, you could upgrade to an underlayment with a fire-resistance rating of A. This will improve your home's value and provide better protection against fires caused by lightning.

4. Your warranty will remain intact

Many shingle manufacturers require roofing contractors to remove the old underlayment and replace it with a new underlayment before they place a new shingle roof. This ensures that your new shingle roof lasts as long as it should, and ensures that your roof's warranty remains intact.

Are you about to replace your roof? Then be sure to ask your roofing contractor to replace the old underlayment to ensure your new roof has adequate protection for many years to come.
