Removing roof shingles might seem like a straightforward task, but trust me, it’s anything but simple. Sure, tearing off those old, worn-out asphalt shingles can be satisfying with your old garden fork, but the devil is in the details.
From the safety precautions to the nitty-gritty of the shingle removal process, there’s a lot more to it than just a strong back and a sturdy ladder. Properly removing old roof shingles is crucial to ensure the integrity of the new roofing system.
Here at Whalley’s Four Seasons Roofing (W4SR), serving Calgary, we’re here to help you navigate through this complex process through a cautionary DIY guide.
We’ll cover everything from recognizing when you need to replace those shingles to the final clean-up, all while sharing some tips and tricks.
And remember, if at any point you feel in over your head, W4SR is just a call away. After all, sometimes it’s best to let the pros handle it – your back (and roof) will thank you.
Preparing is just as important sometimes as the work itself. Now for us, it’s second nature, and we can get started pretty quickly, but if it’s your first time, really make sure you’re ready as
Having roofing underlayment and roofing nails ready before starting the tear-off is crucial to ensure a smooth process.
Before you start tearing up your roof, it’s essential to know when it’s time to replace all the shingles (or just a repair). Look out for the telltale signs of aging or damage:
Make sure you’re aware of Calgary’s local regulations. Generally, you don’t need a building permit for roof shingle removal unless you’re making structural changes. For more details, visit the City of Calgary’s permit information.
Now, if you really wanted to, you could get the job done with whatever you have in your garage.
But as you probably know, nothing beats the right tool for the job (like a broom magnet) and the experience of using that tool constantly.
Unfortunately, we can’t upload that experience for you to download, but we can go over the tools needed.
You can find these tools at specialty stores for roofing and home centers.
Roofing Shovel: This specialized tool comes with a serrated edge to grip and an additional lever for prying.
If you don’t have a roofing shovel, a square narrow shovel can work, as well as a garden fork in a pinch for your roofing tear off.
Hammer: A standard claw hammer is essential for pulling out stubborn nails left behind. While you can use other tools to remove nails, nothing beats the precision and ease of a hammer.
Pry Bar: This flat metal pry bar with a hooked end is essential for prying up shingles and nails during a tear off, especially in tight spots around roof fixtures.
Utility Knife: A sharp, retractable utility knife is handy for cutting shingles, underlayment, or any other material that needs trimming.
Push Broom: A wide broom with stiff bristles is necessary for sweeping away debris and keeping your work area clean and safe. If you don’t have a push broom, any sturdy broom can work, but it might not be as efficient.
Garbage Cans or Dumpster: A sturdy trash container for debris is essential for collecting and hauling away old shingles and other roofing materials.
While you could use heavy-duty garbage bags, a dumpster or garbage cans are much more practical for larger volumes.
Safety Equipment: Safety is everything when working on a roof. This includes fall protection gear, safety harness systems, and safety glasses. A proper safety harness system, is crucial for steep roofs when you remove shingles.
Safety glasses protect your eyes from debris, while work gloves and long pants provide additional protection. Wearing shoes with soft rubber soles and good grip is crucial for maintaining stability.
If your roof is very high, has awkward spots where you could fall, or you start looking into more professional and expensive safety gear, it’s time to call in the pros.
Don’t take unnecessary risks—professional help can prevent severe injuries and ensure the job is done correctly. Safety equipment is non-negotiable for a safe roofing job, as it’s what a roofing professional will use and finally, don’t forget to wear long pants when you remove shingles.
Roof Jacks: Roof jacks are metal brackets that attach to the roof and hold a plank for standing, providing a stable platform that improves safety and comfort.
Here’s a quick guideline:
While not always necessary for shallower pitches, roof jacks are indispensable for steeper roofs.
Ladder: A sturdy, extendable ladder is necessary for safe access to the roof. If you don’t have a ladder, there’s no substitute—it’s a must-have for any roofing project.
Tarp: Large, durable tarps are useful for protecting landscaping and collecting debris. While not absolutely necessary, they are a nice-to-have item that can save you a lot of cleanup time and protect your property.
Roofing Underlayment and Roofing Nails: Before starting the tear-off, make sure you have roofing underlayment and roofing nails ready. These materials are crucial for the subsequent steps in your roofing project.
Remember, this guide covers only the shingle removal process.
Installing a new roof involves additional steps and materials, such as new gutter flashing, a water barrier, felt paper, ice, chalk line and water barrier (crucial for us in Calgary) and don’t forget the new shingles after the tear off. It’s also important to have roofing underlayment and roofing nails ready for the installation of new shingles.
Proper installation is key to a durable and weather-resistant roof.
Also, looking out for damage throughout the process, knowing how to handle areas around plumbing vents the ridge caps, proper installation of ice and water barrier before new asphalt shingles, proper disposal of the trash container and even an air conditioner on your roof.
With all of this in mind, if you’re unsure or need assistance, don’t hesitate to reach out to the professionals at W4SR. We’re here to ensure your tear off is completed safely and effectively.
Now before we start, something to keep in mind is layered shingles when there is more than one layer, the steps compound and require a lot more work. You can read about layered shingles here.

Additionally, ensure you have roofing underlayment and roofing nails ready before starting the tear-off.
Now with those potential problems out of the way, here are the steps.
