Roofing Bar: What is the Best Shingle Pry Bar?

Demolishing an entire roof requires brute force and a massive, heavy-duty tear-off shovel. But what happens when you only need to remove a single damaged shingle in the middle of a perfectly good roof? If you aggressively swing a hammer or wedge a thick crowbar into the tightly glued layers of asphalt, you will crack the good shingles, turning a $50 repair into a $500 nightmare. To perform a delicate, surgical repair, professional roofers rely on a highly specialized piece of incredibly thin steel: the roofing bar.

Before you climb onto the roof to patch a leak, you need to know how much material you are dealing with. Use our Free Roofing Calculator right now to compute your exact roof surface area and generate a mathematically flawless estimate in seconds.

What is a Roofing Bar?

A roofing bar (also known as a shingle pry bar or a roof snake) is a highly specialized variation of a standard flat pry bar.

• The Design: It is usually forged from a very thin, flat piece of hardened steel, measuring about 12 to 15 inches long.
• The Claws: One end features a very sharp, thin V-notch (a cat’s paw) designed to hook around the shaft of a roofing nail.
• The Profile: Unlike a standard pry bar that features a massive, aggressive 90-degree curve at the end, a roofing pry bar is almost completely straight and incredibly flat.

Why You Need a Roofing Flat Bar (Not a Crowbar)

When you need to remove a damaged shingle, you must pull out the nails holding it down. However, the nails holding it down are completely hidden underneath the good shingle directly above it.

If you try to shove a thick, curved crowbar underneath the good shingle, you will bend the good shingle far too high into the air. Because asphalt shingles are stiff and brittle (especially in cold weather), bending the shingle backward will instantly snap the fiberglass mat, permanently destroying it.

Because a roofing flat bar is practically paper-thin and perfectly straight, you can slide it deep underneath the good shingle to reach the hidden nails while only lifting the good shingle a quarter of an inch.

How to Use the Roof Shingle Pry Bar

Here is the exact method for surgically removing a broken shingle:

1. Slice the Tar: First, slide the flat, sharp edge of the roofing bar under the damaged shingle to slice through the sticky factory tar line that is gluing the shingles together.
2. Hook the Nail: Slide the V-notch end of the bar directly underneath the good shingle above the damage. Slide it upward until you feel the sharp V-notch hook securely around the hidden roofing nail.
3. Pry Downward: Once the nail is hooked, press downward on the handle of the bar. Because the steel is so flat, it creates massive leverage directly against the plywood deck, popping the nail cleanly out of the wood without bending or cracking the good shingle resting on top of the bar.

The Shingle Installation Feature

The most premium roofing bars (like the famous Malco Roof Snake) feature a brilliant secondary function on the opposite end of the bar: a magnetic nail-driving slot.

Once you remove the broken shingle and slide a brand new shingle into the hole, you have to nail it down. But you cannot swing a hammer, because the good shingle is in the way of your hammer swing. Instead, you place a new nail into the flat magnetic slot on the end of the roofing bar. You slide the flat bar (holding the nail) underneath the good shingle, and you simply strike the exposed end of the bar with your hammer. The flat bar drives the hidden nail perfectly flush, completely protecting the good shingles from your hammer blows.

Conclusion: The Surgical Hand Tool

A massive crowbar is for destruction; a roofing bar is for preservation. By investing $20 into a paper-thin, specialized shingle pry bar, you give yourself the ability to slide invisibly between the tight layers of a roof, extract hidden nails, and execute a flawless, invisible repair without causing thousands of dollars in collateral damage to the surrounding shingles.

If you discover that the shingles are too brittle to patch and the entire slope is failing, a pry bar will not save you. Head over to our Free Roofing Calculator right now.

Frequently Asked Questions

Do I pull the nails from just the broken shingle?

No. Because asphalt shingles overlap in a staggered brick pattern, the row of nails securing the good shingle above also penetrates the top edge of the broken shingle. To pull one broken shingle out, you must use your roofing bar to pull the nails holding the broken shingle, AND the nails holding the good shingle directly above it.

Why is my roofing bar ripping through the nail head?

If the roof is very old, the galvanized roofing nails may be severely rusted. When you apply massive leverage with the pry bar, the rusted head of the nail will snap off, leaving the sharp shaft stuck in the wood. If this happens, you must aggressively dig the V-notch of the pry bar into the wood deck to grab the bare shaft of the nail and pry it out, or it will puncture your new shingle.

Can I use a roofing bar in the winter?

It is highly discouraged. Asphalt shingles become incredibly stiff and brittle in freezing temperatures. Even with a paper-thin roofing flat bar, lifting the good shingle a quarter-inch to slide the bar underneath will cause the frozen fiberglass mat to crack in half. You should always wait for a warm, sunny day so the shingles are soft and pliable.
