You have two options when it’s time to do a roof replacement: either tear off the old roof and replace it or add a new layer over the existing roof (what we call an overlay). While tear-offs are often the more practical choice, there are instances where overlaying is more applicable.
In this post, Stapleton Roofing discusses what overlaying is and when is it the practical choice when replacing the roof.
Overlaying: When Is It the Practical Choice?
As its name suggests, overlaying involves adding a new layer of shingles on top of the old roof. It’s easier to do and is less labor intensive than a complete tear-off. More importantly, it’s less expensive due to the shorter construction period required by the roofers. Overlaying is a good method if you need a new roof immediately and if the main structures holding your roof are still relatively intact.
Things to Keep in Mind
Keep in mind that while there are some instances where an overlay is a more practical choice, it’s not necessarily the better choice. Overlaying is like putting a BAND-AID® on the roof; it addresses the existing concern, but it doesn’t really improve the condition of the roof. This is why your new roof needs to be still structurally intact for a successful overlay.
In addition, remember that laying down a new layer of shingles adds extra weight on your roof that your home may not be able to support. Always have a roofer do an inspection of your roof if you are considering an overlay.
Finally, look at overlaying only as a temporary fix. The new layer of shingles won’t last as long as they should since they’re laid over the old roof. This process can also trap heat between the layers. Overlaying can address the immediate effects of a storm-damaged roof, but a more long-term solution is required to address underlying problems, such as leaks.
