If you decide to just place new shingles on top of your existing roofing underlayment, then it might cause huge problems later on in the roof’s lifespan. This is especially true if your roofing underlayment is really old and nearing the end of its service life. With a complete roof replacement, you can tear off all the existing roofing components until only the deck remains and have new ones installed in place of the old parts.

With this approach, you can be sure you’ll have nothing to worry about for years to come. Hill Roofing Corporation, the top local provider of roofing and siding services, explains why you should consider having a total tear-off for your roof installation.
- It can reveal hidden problems. Tearing off the underlayment and the rest of the roof completely can reveal what’s underneath your old roof. It helps you see if your roofing system has developed underlying issues like rot or mold over the years. As such, you can take action on these problems before installing your new roof to make sure it will deliver superior performance for years to come.
- It can help you maximize your roof’s lifespan. A complete tear-off job will last you much longer than an overlay will, and this is mostly because a new roof traps less heat than a system with multiple layers. As an experienced roofing contractor, we know that additional heat can cause shingles to curl and break down faster, resulting in premature roof replacement.
- It ensures comprehensive warranty coverage. Your warranty is another reason why you need to replace your old underlayment. Warranties can help you cover the costs of repair jobs, but most roofing warranties can be voided if the shingle isn’t installed according to manufacturer specifications.
