Roofing Nails Per Square
Most shingle manufactures recommend using four nails per shingle on the main area of your roof and five nails per square in the first row of roofing. This adds up to an average of 320 nails or 100 square feet. If you have high wind areas, you will want to use five nails pers shingle, equating to about 480 per square.
When using a 1.5-inch roofing nail, they usually have a large 11-gauge shank and an oversize, 7/16-inch flathead. These nails are hot galvanized, which helps them withstand sun and rain on your roof. About 140 of these types if nail weighs one pound. You will need approximately 2 ¼ pounds of nails to install a square of shingles in regular conditions, and about 3 ½ pounds if you are dealing with windy conditions. Because nails are purchased by the pound, so can ask your supplier for the correct number of nails for your size roof, in the length you specify.
How Long Should Roofing Nails Be
The International Building Code does not specify specific lengths for shanks, but does state that the nail must penetrate through the roofing materials and must not be less than ¾ inch into the roof sheathing.
The guidelines for nail length are more vague than diameter, so youll find a greater variance of size depending on the shank type. Wood shingles require a longer shank than an architectural shingle and fiberglass shingles are the same as asphalt-style.
How Many Coil Roofing Nails Per Square
Roofing nails are used to attach shingles to the roof. The number of nails per square is dependent on the type of roof and exposure to the elements. For example, a roof that is covered by a single-ply shingle may require as many as 25 nails per square. In contrast, a roof covered with a heavier material such as metal will require at least two additional nails per shingle.
The cost of roofing nails varies depending on the material, type, and length of nails used. Roofing nails are generally sold by the pound, so they may be cheaper if you buy them in bulk. For example, a five-pound box of smooth-shank galvanized steel roofing nails costs about $10.
The cost of nails used for roofing felt will be more expensive than standard nails. In addition, the number of nails needed for one square may differ from another, depending on where you live.
Roofing manufacturers generally recommend using four nails per square of shingles and five nails per square of underlayment. If you live in an area where there is a lot of wind, you may want to use more nails. Some manufacturers suggest 480 nails per square for high-wind areas.
Roofing nails are typically 1.5 inches in diameter and have an 11-gauge smooth shank. These nails are also durable and hot-galvanized, which means they are resistant to rust, corrosion, and extreme weather conditions.

How Many Nails Should Be Used Per Shingle
Weve had some pretty bad thunderstorms in our area lately, with really strong winds. Many of our neighbors have ended up with some shingles missing, blown down the street, or strewn about yards. As I took a walk this morning, I noticed some shingles still had nails in them. I started to wonder how many nails should be used per shingle.
Manufacturers recommend 4 nails per shingle for standard slopes from 4:12 to 9:12 and five nails per starter shingle. Anything less than four will void any warranties offered. For steep slopes and high wind areas, use 6 nails per shingle. Nails must be long enough to penetrate at least ¾ into the roofing sheathing.
In this article, well go over everything you need to know about nailing shingles to your roof, whether its your house, shed or even a doghouse. Well also cover other types of shingles, such as ridge cap shingles, so there wont be any questions when it comes time for you to shingle your roof.
How Many Nails Per Shingle Gaf
When installing asphalt shingles, its important to know the right number of nails per shingle. This is especially true when youre working in a high-wind area. GAF recommends using four, five, or six nails per shingle, depending on the size and type of shingle.
The nails in GAF shingles go through a black marker strip. Its best to start by nailing the first full sheet, then add nails at the proper intervals. The spacing between the nails should match the distance between the shingles and the local building code.
Some roofers believe that heavier shingles are more durable and robust. However, GAF and CertainTeed both make shingles that are lighter in weight and have fewer nails per shingle. Although many factors may affect the weight of shingle, the placement of nails matters more than most others. CertainTeed, for example, has a unique system called NailTrack, which has a 1.5-inch-wide nail area.
Nails are important because they hold the shingles in place. They should be evenly spaced to avoid splitting the wood and ensure maximum support. A nail placed too high or too low will expose the shingle underneath.
Moreover, the nails should be positioned so that they are evenly spaced along the entire roof. The outermost nails should be driven about an inch away from each edge of the shingle, while the innermost nails should be driven slightly above cutouts.

Steep Slope Or High Wind
Very steep slopes, also called Mansard roofs, as well as areas with extremely high winds, require six nails per shingle to allow enough hold against the elements. The extreme slope means that not only is there a larger pull from gravity on each shingle, but also substances are going to flow faster across the surface. The added friction requires more nails in order to adequately hold the shingle in place. There is no reason six nails cannot be used on a standard roof, but with the extra money and time necessary to add the extra nails, it is often considered unnecessary.

Can Roofing Nails Be Used For Siding
There are a few differences between roofing nails and siding nails. The first difference is the purpose of the nail. Roofing nails are designed to penetrate the wall fully while siding nails are meant to come out.
Roofing nails are generally longer and have a head that is less pronounced. Siding nails are usually shorter and thinner and have a ring shank instead of a head.
You can use roofing nails for siding, but you must be careful to choose the right ones. For vinyl siding, you need to choose nails that have a head that is an eighth of an inch.
This will ensure that the nailhead is not visible. In addition, you should use galvanized nails for siding projects. These will last much longer than regular nails.
If youre unsure whether to use roofing nails or siding nails, its best to choose the latter. Siding nails are much smaller, have a smaller head, and will not hold shingles in place, as well as roofing nails. They will also bend and break easily if theyre used in a roofing nailer.
How Far Apart Should Roofing Nails Be

You should also make sure your roof is properly ventilated.

How To Fix Nail Pops In A Roof
Nails can pop above the roof surface for a number of reasons. Perhaps they were underdriven in the first place. Nails that didnt fully penetrate the sheathing may work their way up over time. Or, if a roofs decking has warped or bent, it can pull nails out of place. Whatever the cause, its important to fix any nail pops in a roof to prevent damage.
Fixing the nails is simply a matter of removing them, removing the shingle and installing a new shingle. Be sure you to use the correct nail length and place it properly.
Do not simply hammer the nail down, renail it in the same spot, or use the same shingle. All of these methods could allow water through the roof. For example, if you remove the nail and drive it back into the same spot, your aim wont be perfectly accurate. There will be a tiny gap on one side of the nail or the other. Even if it is imperceptible to you, water will find it.
If you use the same shingle and add the nail back in a different spot, youre leaving behind a hole where the nail once was. Some suggest you fill this hole with roofing cement, but this repair option must be done carefully to maintain the roofs water-shedding performance.
How Many Nails Are Used Per Shingle
Most shingle manufacturers recommend at least four nails per shingle and six in high wind areas such as Florida and Oklahoma. That answers the question about the minimum number of nails and were sure you realize that the minimum will be good enough for fast buck roofing companies, plus theyll use the cheapest roofing nail they can find.
Answering the question about how many nails we use per shingle is a bit different and well go light on the technical details yet not so light that we end up being vague. We use 4-6 nails per shingle, depending on the area and steepness of the roof. Let us explain a bit more.
First, our nails are 1¼ inch hot dipped galvanized, ring shanked for extra bite versus a smooth shank that is less secure. These nails are installed using an air driven nail gun to assure the shingles are fully secured. Each nail actually goes through two shingles the one that is getting nailed and the one underneath it. That is why every shingle is actually getting 12 nails.
The value of how many nails we use, and the type of nails, has less meaning without converting it to how much wind your roof will withstand. Our installation method will endure hurricane velocity winds exceeding 130 MPH. Thats beyond even the worst gusts you should ever have to worry about in Southeast Michigan.

What About The Waste Factor Should I Order Extra Roofing Materials
You want to order extra material to account for waste. Waste factors vary.
10%-15% is a good rule of thumb, but your results may be different. More complicated roofs will have a higher waste factor because there are usually more cut shingles around corners, walls, and edges.
It is okay to have a few shingles left over. They can be saved in case there is roof damage later or if repairs need to be done in the future.
So for the 24 square roof example, you would want to add 2.4 squares which equal about 7 or 8 more bundles.
Lay The Subsequent Rows
- 6.1 âStart off the first row with a whole shingle.
- 6.2 âPlace the shingle in the starting corner in such a way that the last shingle will overhang the fascia board by 3/8â³.
- 6.3 âDrive in 4 straight nails only until the nail heads make contact with the asphalt. Avoid tearing.
- 6.4 âStagger each new row by a half-tab.
- 6.5 âAlign the lower edge of the shingle with the top of the notches on the preceding row.
- 6.6 âRepeat for every row.
