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 two layers is more applicable. When looking at roof overlaying pros and cons, it’s important to keep in mind that adding extra layers of shingles temporarily fixes a roof. Knowing when to get overlay roof systems and when a full tear off roof replacement is needed is important.

Roof Overlaying: New Roof over Existing Roof


Stapleton Roofing’s team of roofing experts has worked with clients throughout Arizona for both roof replacement and roof overlay. Here, we have discussed the question of is roof overlay practical, and when is it a good idea to get?

There are Pros and Cons

In this post, Stapleton Roofing discusses when is this type of installation the practical choice when replacing the roof. Understanding roof overlaying pros and cons, when is roof overlay practical for a roof, when to overlay roof structures or replace them, and how extra layers of shingles and roof overlay temporarily fixes roof problems that will require more intensive repairs later can help you determine next steps for your roofing project.

When it’s Time to Tear Off

Overlay might be a good way to repair minor roof problems temporarily, costing you less than a complete roof replacement. It could even extend the life of your current roof slightly longer if done at the right time. However, there are times when overlay roof won’t work, and times when overlay might not save you money or time on your roof or asphalt shingles because more serious repairs or a new roof were actually needed. You can always have a professional like Stapleton Roofing assess your existing roof’s condition and discern whether overlaying your roof or to tear it off is a wiser option.

Overlay: When Is Roof Overlay Practical?

As its name suggests, overlay involves adding one new layer of shingles on top of the existing 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 reduced construction time roofers need. Covering existing shingles with extra shingles is a good method if you need a new roof immediately and if the wood and metal structures holding your old roof are intact without damage like leaks.

When considering roof overlaying pros and cons, the relative ease of using two layers, the lower cost and labor required, and the lesser investment draws homeowners to roof overlay. These advantages can be strengths for a roof that’s in good condition and can afford some years before it really needs replacing. Overlay temporarily fixes old roofs and gives it a new look without the cost to remove asphalt shingle roofing.

Keep in Mind for When to Overlay Roof Structures

When looking at overlay roof pros and cons, you will want to pay attention to the drawbacks of covering your roof as well. When asking yourself “is roof overlay practical for my roof?”, consider the age and condition of your roof. You cannot continue to overlay a roof indefinitely, especially if the roof is in rough condition. Overlay roof temporarily fixes problems with roofs, but those problems will eventually need to be addressed more directly.

Temporary Solution

Keep in mind that while there are some instances where an overlay is a more practical choice, it may not necessarily be a better choice if the roof has real damage like leaks. Multiple layers of shingles 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.

Additional Weight to Install

In addition, remember that laying down a new layer of shingles adds extra weight on your existing 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.

Shingles will Last Less Time

Finally, look at overlay roof 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 shingles, metal components, and wood supports. This process may also trap heat between the layers. Multiple layers of shingles 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. Know how an overlay roof could affect the home s resale value.
