So you need a new roof! Typically, your builder will provide two options: (1) overlaying the new roof over the existing layer of shingles or (2) tearing off the old shingles before installing the new roof. Although most people will assume that the second option is best (why keep the old and damaged shingles?), overlaying provides several benefits as well. Tear-off vs. overlay roof: which is best for your home? If you need help deciding, scroll down for an overview of the pros and cons of each option.
Tear-Off vs. Overlay Roof
Tear-Off Roof
PROS
- Allows you to inspect the condition of the decking and search for leaks or damage

CONS

- Costs more money due to labor and disposal costs
Overlay Roof

- Does not allow for the addition of an ice or water-leak barrier (which must be attached directly to the decking)

Every home is different, of course, so be sure to take your existing roof’s condition into account. If your roof already has multiple layers, for example, building codes may require that you tear-off the existing layers and start from the scratch. In addition, if you’re planning to use heavy-duty shingles to cover lightweight shingles, you may have good luck with an overlay roof.
The primary reason that homeowners choose to use an overlay roof is the low initial price, so if you’re looking for savings, ask your roofer whether an overlay roof is possible. If you’re in this for the long haul, on the other hand, and want a quality roof and an undeniably healthy structure, you might prefer a tear-off roof. Finally, if you need help making up your mind, ask your roofer for advice!
