How To Estimate How Many Roofing Nails Are Needed

When you go to the store to buy roofing nails, you will be buying them by weight, not number. Containers of roofing nails will indicate how many pounds of nails it contains, not necessarily a number. Therefore, you need to know how much a nail weighs so you can estimate the number of nails youll be buying.

Knowing the total amount of shingles, youll need for your roof will allow you to calculate the nails needed. Youll use starter strips on the eave and rake ends, and any gable ends you might have. Youll add up the linear feet of starter strip shingles required.

If that is 300 feet, and we know that 16 shingles cover 50 feet, that means youll need 96 shingles. 96 x 5 nails mean youll need 480 nails just for your starter strip shingles.

For a 2000 square foot roof, youll need 20 squares of shingles. If you use standard 3-tab shingles, youll need 312 x 20, which equals just over 6,200 nails.

Mastering Roof Inspections: Asphalt Composition Shingles Part 26


The purpose of the series Mastering Roof Inspections is to teach home inspectors, as well as insurance and roofing professionals, how to recognize proper and improper conditions while inspecting steep-slope, residential roofs. This series covers roof framing, roofing materials, the attic, and the conditions that affect the roofing materials and components, including wind and hail.

Properly Driven Fasteners

Depth of Penetration

Whatever fasteners are used, they have to be of adequate length. Nails should penetrate a minimum of 3/4-inch into the sheathing, or just through the roof sheathing if its 1/2-inch plywood or OSB. Some manufacturers allow nails with less penetration above exposed soffits if extra nails are used.

Longer nails are required under certain circumstances, such as:

  • when new shingles are installed over existing shingles
  • when thicker shingles, such as high-end, multiple-layer laminated shingles, are used and
  • when fastening hip and ridge cap shingles or ridge vent cap shingles. This is especially true when a continuous ridge vent is installed.

If you see many loose or missing shingles, be sure to check the method of fastening.

Nails and staples have to be driven to the proper depth.

Fastener Placement

Fastener placement is specified by manufacturers, and its often similar for similar types of shingles.

I am hand nailing. 4 nails per shingle. The sheathing is half an inch. Add the shingle plus tar paper. If I were to use a longer nail than one inch, it would go through the roof and I would see it inside of my shed.

Understanding The Specs Of Nails

Understanding how many nails are needed according to the roofing is important.

Typically, you can use 12 to 16 pounds per square inch for asphalt shingles and 15 to 20 psi for architectural shingles.

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.

Improperly Installed Valley Flashing

Valley flashing can only do its job if its layered beneath the shingles. Surprisingly, many contractors will incorrectly install this protective element atop the shingles. Further, failing to use enough sealant and securing materials when installing the flashing can significantly reduce the flashings ability to divert large volumes of water.

Staying Aware Of Your Dumpster Weight


Since dumpster sizes are typically expressed as yardsfor instance, ten yards, or twenty yardsit can be tempting to conclude that your roofing tear off waste comes down to an issue of length.

Typically, though, with roofing projects, its more about the weight. Shingles are heavy, and can easily surpass the weight limits for dumpsters if youre not careful. Calculating weight for your roof tear off is by no means a precise science, but you can get a general feel for the heft your shingles will have once theyre piled into a dumpsterand it depends on what theyre made out of, the size of your roof, and how many layers you have installed on your roof.

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.

Its not wise to attempt to reuse them, as they may cause problems on the new roof.

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.

Synthetic Underlayment Is Now Safer


When synthetics first came out, one of the main complaints was that they got slippery when wet. Exactly the opposite is true these days. Some types of synthetic underlayment actually gets a little tacky when wet. Improved walkability alone is the reason many roofing contractors have made the switch from felt.

Choosing The Right Size Length And Gauge Of Nail

To narrow the selection down from the many types of roofing nails available, it helps to know what you are looking for before you consider making a purchase. As with any type of nail, roofing nails can be bought in a range of different lengths, sizes and gauges.

Roofing nails tend to be available in lengths ranging between 25mm to 152mm. In most cases a roofing nail is between 25mm to 60mm. Any nail that is longer than 152mm is instead called a pike and is not suitable for use in roofing projects as it would penetrate too deeply into the cover materials and beyond.

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.

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 Roofing Nails In A Pound


Using a nail weight chart will tell you that it takes 160, 11 gauge 1.5 roofing nails to make one pound of nails. It is more common to buy 5 pounds or more of roofing nails. Using the same type of nail means 5 pounds of nails will give you 800 roofing nails enough for 2.5 squares of standard 3-tab shingles.

If we take a 2000 square foot roof as an example, we know we need about 6700 nails to finish our roof. How many pounds is 6700? We know 160 nails equals a pound. If we divide 6700 by 160, we get a number close to 42. That means well need 42 pounds of standard 11 gauge roofing nails for a 2000 square foot roof.

How Many Roofing Nails Per Bundle

The price of roofing nails varies widely depending on the type, size, and length of the nails. Typically, nails are sold per pound and cost between $8 and $14 per bundle. Buying roofing nails in bulk can be an effective way to save money, especially if youre a professional roofer. For instance, a small box of five pounds of smooth-shank galvanized steel roofing nails can cost as little as $10. However, nails used for roofing felt are usually more expensive.

When choosing roofing nails, keep the weight of your roof in mind when determining the number of nails you need. Generally, most manufacturers recommend using four nails per shingle, or about 320 per square foot. However, if you live in a high-wind area, you may want to use more nails.

The most commonly used nails are one-and-a-half inch long, with a 7/16-inch flat head and an 11-gauge shank. These nails are hot-galvanized to withstand extreme weather.

Roofing nails are used for a variety of applications, including ridges, valleys, hips, and flashing. One box contains approximately 7,200 nails, and each coil contains approximately 120 nails. This is enough for 21 squares, depending on the type of roofing materials used.
