Roof replacement will become a necessity at a certain point. When that time finally arrives, you may be faced with the question of whether to remove the old underlayment or keep it in place. Generally, a total tear-off — which means replacing the entire roof system — is the best way to go.

In this post, trusted roofing and siding contractor Polar Bear shares some of the benefits of a complete roof replacement.

Why Are Tear-Offs More Often Recommended?

For roof replacement projects, roofers are often required to do tear-offs due to building codes or manufacturer warranties. And generally, a tear-off results in a longer-lasting roof, so it is more frequently recommended than reroofing (a method that allows new shingles to be installed over old shingles).

Below are some of the benefits of a total tear-off:

• A tear-off enables your contractor to inspect the roof decking for rot, mold or any damage that would compromise the integrity of your new roof. This gives you the chance to ensure the optimal performance of your new roof.
• Underlayment is a layer found underneath your shingles. Typically, if your shingles have already aged or started deteriorating, you can expect the underlayment to be in the same condition. That said, a complete tear-off would naturally make more sense.
• Whether you are replacing Polar Bear roofing or windows, warranty should always be considered. Always review the details of your warranty before doing any work on your roof so as to avoid the risk of your warranty not being covered.
