How many boxes of coil nails per square

Usually use 3 roofing nails per 36" 3-tab, and either 4 or 5 on a 40" architectural, depending upon manufacturer's specs for their warranty.
The number of shingles in a 10' X 10' square depends upon the type of shingle, of course, and the number of nails per shingle depends on manufacturer's specs.
If you're in a high wind area prone to hurricanes or hurricane force (74 mph+) winds, then I would pop an extra nail above the manufacturer's recommendation.
Easy to figure the numbers from there.
I have 40-year architecturals that recommended 5 in all end shingles and 4 in the field, but I had 5 put in every shingle, PLUS I had all edges tarred down, because I'm in a hurricane area. My 32' high A-frame roof has been through several hurricanes, including a direct hit by Isabel Sept. 2003, and my 1991 roof has never lost a shingle.
Build for where you're at, and don't skimp on roofing nails. And about 6" of that black plastic roofing cement under the edges really helps, too.
I'm not a roofing pro. This is just my opinion, and it has worked for me.
Good luck!

If you plan on installing asphalt shingles on your roof, it's important to keep track of how much weight they add to it, especially if your framing and foundation are old. To get an accurate assessment, you need to include the weight of the nails you use to hold them down.

Nail Quantity per Square

Shingle manufacturers recommend using four nails per shingle in the main part of the roof and five nails per shingle in the first row, says Owens Corning. This amounts to an average of 320 nails per square, or 100 square feet. In high-wind areas, you need five nails per shingle, or 480 nails per square. One-and-a-half-inch roofing nails typically have a large, 11-gauge shank and an oversize, 7/16-inch flat head. Moreover, they are hot galvanized to help them withstand the rain and sun on the roof. Approximately 140 of these nails make a pound, reveals Tree Island's nail weight chart, so you need about 2 1/4 pounds of them to install a square of shingles in normal conditions and about 3 1/2 pounds in windy conditions.

Most shingle manufactures recommend using four nails per shingle on the most area of your roof and five nails per square within the first row of roofing. This adds up to a mean of 320 nails or 100 square feet. If you’ve got wind areas, you’ll want to use five nails per shingle, equating to about 480 per square.

When employing a 1.5-inch roofing nail, they typically have an outsized 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 those types if nail weighs one pound. you’ll need approximately 2 ¼ pounds of nails to put in a square of shingles in regular conditions, and about 3 ½ pounds if you’re handling windy conditions. Because nails are purchased by the pound, so can ask your supplier for the right number of nails for your size roof, within the length you specify.

ESTIMATING SHINGLES NEEDED

To gauge how many shingles you’ll need, you’ll first got to estimate the total square footage of your roof’s surface. this will be done by measuring the length and width of every plane on the roof, including dormers. Next, you’ll multiply length x width to urge the square footage of every plane. Finally, calculate your roof’s total square footage by adding the square footage of each of the planes together.

For example, a shed roof has one roof plane. you’ll simply measure length (A) x width (B): A x B = 120′ x 100′ = 12,000 sq. ft. for the entire square footage of the roof.

Another example may be a gable roof that has two planes. Therefore, you would multiply length (A) x width (B) to get the square footage for every plane. you’ll then add the 2 planes together to derive the entire square footage of the roof:

• Plane One: 120′ x 100′ = 12,000 sq. ft.

• Plane Two: 120′ x 100′ = 12,000 sq. ft.

• Plane One + Plane Two = 24,000 sq. ft. gives you the entire square footage of the roof.

The surface of your roof is measured in “squares.” A square is an area of roof which equals 100 square feet. To calculate the number of squares on the saddle roof above, you’ll simply divide its total of 24,000 square feet by 100. The result’s 240, which suggests you’d need 240 squares of shingles to hide that roof. the foremost common sort of shingle is named a three-tab or strip shingle, and that they usually come packaged three bundles per square.

If you’re putting in a replacement roof, you’ll also need an equivalent amount of underlayment. So, using the saddle roof example above, you’d need 240 squares of underlayment. Underlayment most frequently comes in rolls of 4 squares each. So, so as to hide 240 squares, you’ll need 60 rolls of underlayment.

You will also be got to know the slope of your deck. you’ll do that by measuring the vertical rise of your deck in inches over a 12″ horizontal distance. If you found the increase is 4″, then your roof slope is 4 in 12. The slope of your roof is usually specified with the vertical rise winning, and therefore the horizontal run (12″) mentioned second.

What if your roof is steep?

In order to live a steep roof, you’ll need to use an alternate method. To calculate the roof length, first, measure the outside walls the add the overhang for the length of the house parallel to the ridge. Next, employing a rope, you’ll throw it over the ridge and mark it on each eave. this provides you the width dimension to use in figuring your area. confirm you are doing this for every roof section containing a horizontal ridge.

Be sure to measure the lengths of your rakes and eaves to work out the amount of drip edge needed. Always remember if you’ve got any questions about your supply estimate, ask a roofing contractor in your area. Many are happy to give you a free estimate.

Health effects from being exposed to asphalt fumes include skin rashes, headaches, cough, sensitization, reduced appetite, fatigue, throat and eye irritation, and carcinoma.

Studies showed a connection between cigarette smoking and carcinoma for several years. However, the govt refused to officially recognize this for many years. Usually, by the time the govt is ready to declare a cloth to be harmful, there’s overwhelming and indisputable evidence. Even though modified bitumen is considerably less carcinogenic than pitch, it still includes polycyclic aromatic hydrocarbons (PAH) in it. Several studies have shown evidence of carcinogenicity in mice after applications of laboratory-generated asphalt roofing fume condensates were applied.

Neoprene 

When neoprene is heated it can discharge dangerous acid into the air. Neoprene is typically safe. Also, the manufacturing of neoprene releases harmful toxins into the air.
Many people with skin sensitivities, like dermatitis, may have allergies after wearing clothing with neoprene in it. this is often due to diallyl thioureas, which was called the allergen of the year in 2009.It is the explanation for many skin reactions. Unless you’re currently allergic to neoprene, it’s typically considered safe to be worn for many people.

Xylene

Xylene is a common solvent found in many construction adhesives. it’s not safe to inhale xylene fumes. The California Department of Health Services stated: “Xylene enters your body rapidly once you inhale its vapors. It also can be absorbed through your skin, particularly if the period of contact is lengthy. Overexposure to xylene most commonly affects your nervous system, system respiratory, and skin.”
