Should I Remove Shingles Before Installing Metal Roof?
When it comes to installing a new metal roof, one of the most common questions homeowners ask is whether they should remove the existing shingles first. The answer to this question is not a straightforward one, as it can depend on a variety of factors. In this blog post, we’ll discuss the pros and cons of both approaches to help you make the most informed decision.
Leaving Shingles On: The Pros and Cons
Pros
- Cost-Effective: One of the most significant advantages of installing a metal roof over existing shingles is the cost savings. The labor and disposal costs associated with shingle removal can be avoided.
- Time-Saving: Shingle removal is a labor-intensive process that can add considerable time to your roofing project. Installing the metal roof directly over the shingles can expedite the project.
- Extra Insulation: Leaving the shingles in place can provide an additional layer of insulation, which can help improve your home’s energy efficiency.
Cons
- Potential for Hidden Damage: If the shingles are left in place, any underlying damage or issues (such as rot or mildew) may go undetected.
- Weight Issues: While metal roofs are typically lightweight, adding them on top of existing shingles can put extra weight on your home’s structure.
- Uneven Surface: Shingles may create an uneven base for your metal roof, potentially leading to aesthetic and functional issues.
Removing Shingles: The Pros and Cons
Pros
- Thorough Inspection: Removing the old shingles allows your roofing contractor to inspect the deck for any damage and repair it before installing the metal roof.
- Lighter Load: By removing the old shingles, you’ll decrease the weight load on your home’s structure.
- Clean Aesthetics: With the shingles removed, the metal roof can lie flat and neat, providing a more appealing aesthetic finish.
Cons
- Higher Costs: The removal of shingles will add to the overall cost of the project due to increased labor and disposal costs.
- Longer Project Timeline: Removing the shingles can extend the timeframe of the project.
- Potential for Extra Noise: Without the additional layer of shingles beneath, noise from rain or hail might be more audible inside the house.
Conclusion: It Depends!
Whether or not to remove shingles before installing a metal roof depends on your home’s specific situation, local building codes, and your long-term plans.
If your shingle roof is in good condition with no signs of water damage or severe aging, installing a metal roof over the shingles could be a cost-effective, time-saving option. However, if there are signs of underlying damage, it’s often better to remove the shingles, make any necessary repairs, and then install the metal roof.

hey Moffatt Bros. Roofing, so ya think it’s a good idea to just slap the metal right on top of the old shingles? won’t it cause like issues or something?
hey, can u just slap the metal on top the old shingles or nah? gotta know asap!
Not the best idea, TimboSlice. It can trap moisture and cause more issues down the road. Better off removing them first.
I read in another article that removing shingles before installing a metal roof can help with insulation issues. Is this accurate, or was that information outdated?
That’s not entirely true, Jen. While removal can help spot insulation problems, modern metal roofing tech can work around that without needing to strip to bare decking.
this sounds like too much work. why even bother with metal if it’s this complicated? smh
does removing shingles first cost a lot more? trying to budget this whole reno thing, lol.
So you’re telling me I could’ve saved my back and just thrown the metal on top? Guess me and the boys turned it into a workout session for nothing, eh?
love the idea of not dumping more stuff in a landfill. if putting metal roofs on top of shingles is cool for the environment, then I’m all for it!
Really appreciate this info! Was talking to my landlord about getting our roof more environmentally friendly and this metal roofing option sounds like a win. Gonna suggest removing the shingles first to avoid any issues. Thanks, Moffatt Bros. Roofing!
Removing shingles can uncover lots of hidden problems like leaks or rotten decking. It’s often better to know what you’re dealing with beforehand.
But doesn’t removing shingles just add to the waste problem? There’s gotta be a balance, right?

if i put metal over the shingles, do i need to do something special or it just goes straight over? gotta make sure I’m doing it right.
Just finished installing a metal roof on our cottage and lemme tell ya, removing the shingles was a pain but so worth it! The roof looks amazing and feels super sturdy. Didn’t know about the risk of moisture trapping if you don’t remove the old shingles. Good thing we did it right. For those wondering, it took a lot longer than expected but the peace of mind is worth it.
It’s fascinating how the decision to remove or not remove shingles before installing a metal roof impacts both the environment and the building’s integrity.
I did a ton of reading on this and most experts seem to agree that removing the old shingles is crucial for the long-term health of your roof. Trapped moisture sounds like a nightmare waiting to happen.
So, we’re just gonna ignore the fact that skipping the removal process might just be cutting corners to save a few bucks, huh?
So glad I stumbled upon this article! Was on the fence about keeping the shingles or not. Decision made! Thanks for the clarity!
sounds like a plan to save some cash on roof work, but wondering if this will bite me later with some unexpected costs?
lol imagine thinking you can just stack roofs like pancakes. aint how it works, folks.
First time hearing about metal roofs, sounds awesome! Gonna be my next project. Thanks for the insights!
Could you elaborate on the potential thermal bridging issue mentioned? How significant is it when metal roofing is installed over existing shingles?
So, what’s the real deal with leaving them shingles on when putting a metal roof over? Gotta say, seems kinda lazy not to just rip ‘em off. Thoughts?
I’ve always wondered about the potential damage to a house from adding additional weight with a metal roof over existing shingles. Could this not affect the structural integrity over time, especially in areas with heavy snowfall?

I think metal roofs are great! They last forever and are pretty cool for the planet. Plus, no shingle removal means less junk in our landfills, right?
