If you’re getting a new roofing system for your home this season, you should know that every single component from the old one should be removed. Not just the damaged shingles, but the old roofing underlayment, as well. There are good reasons for this, and Frame Restoration Roofing and Construction, the leading roof replacement company in the area, shares some of them here.

But First, What Exactly is the Roofing Underlayment?
It refers to the thin, waterproofing material typically installed between the roof deck and the asphalt shingles. Also called ‘ice and water barrier’, the underlayment prevents snowmelt or rainwater that has gotten past the shingles from infiltrating your roofing system. With this component in place, the potential for leaks is significantly reduced.
You Should Get a New Underlayment with Your New Roof
The old underlayment won’t be doing your new roofing system any favors, unfortunately. You should have it replaced and here’s why:
- Replacing the old roofing underlayment won’t cost you money. Its removal is usually covered by most insurance claims that require a new roof, so there’s no valid reason to keep it.
- Having the old underlayment replaced will keep your roof warranty intact. Roofing manufacturers have stringent guidelines on how their products should be installed. They’ll always require their certified contractors to remove the old underlayment (and install a new one) so the roofing system can meet quality specifications. If you keep the old underlayment, you could lose the coverage on your roofing warranty.
- Replacing the old underlayment helps make your new roof last longer. That’s because its removal gives your roofer the opportunity to inspect the decking for possible moisture damage. This will need to be addressed before a new roof can be installed. Otherwise, it can cause structural issues in the new roofing system, causing it to fail long before it should.
