How Many Squares Are In A Bundle Of Shingles
One of the hardest home improvement jobs any homeowner can undertake is roofing projects. It is easy to see why so many leave this up to professional roofing contractors.
While this does make a lot of sense, there can still be a good reason to know how many roof shingles you need for your roof.
So you can obtain a good understanding of what you will need, here is all you need to know aboutcalculating the number of bundles and total shingles needed for your roof, regardless of who installs it.
How To Measure A Roof
To measure a roof, you will need to secure a ladder safely to your roof so that you can climb up and get accurate measurements using a measuring tape. If you are unable to secure a ladder to your roof, then you should find a friend or family member you can stand at the base of the ladder and hold it to prevent it from moving. Wear sturdy boots to climb up the ladder onto the roof, and ideally, wear a construction helmet.
Once you are on the roof, you will need to measure the length and the width of the roof. Take care when walking across your roof to not damage the roof and also to prevent yourself from falling off the roof and sustaining injuries.
Take a note of both the length and width of the roof in feet. Once you are back on solid ground, you can multiply these two numbers together to find the total square footage of the roof. For example, if your roof is 80 feet wide and 25 feet long, then you will do the calculation of 80 multiplied by 25, which would give you the result of 2000 square feet.
Once you have the total area of your roof in square feet, it is a simple calculation to find out how many squares your roof has. You will need to divide your square foot result by 100. Following on from our earlier example, a roof with a square footage of 2000 would need to be divided by 100, giving the result of 20.
Though it may seem like an overly complicated method of measurement, it actually makes the whole process of roofing much simpler once you have the hang of it.
Can You Get Multiple Vaccines At Once
The technical term for getting multiple vaccines together is âvaccine co-administration.â Medical professionals say the answer to whether this is a good idea depends largely on your age and health status, the vaccines youâre considering, how urgent the need is to start building protection, and personal preferences.
As a general rule, there are very few vaccines that canât be co-administered, says L.J Tan, MS, PhD, an infectious disease specialist and the chief policy and partnership officer at the Immunization Action Coalition in St. Paul, MN. However, Dr. Tan says, there are some vaccines that definitely donât belong togetheradding that when vaccines are co-administered, they should go in different anatomic sites . âIt can be in the same arm if they are spaced an inch apart,â he says.
This allows your doctor or pharmacist to identify which vaccine caused a reaction, should one occur.

Factors To Consider Before Buying Shingles

When it comes to understanding the roofing industry and what youll pay for shingles, you need to know some industry terms. One such term is roofing square. A roofing square is equal to 100 square feet.
Dont make the mistake of confusing a single roofing square with a square foot. When you buy shingles, most contractors will quote you in roofing squares.
If your homes roof measures 600 sq. ft, it equals 6 roofing squares. It is mandatory to understand this terminology to determine the weight of your roofing material.
One interesting aspect of the roofing business is that you sell roof shingles in squares, but people buy them in bundles.
A rule of thumb is that one bundle of shingles can cover one-third 1/3rd of a roofing square.
Remember, the thicker the bundle of shingles is, the more durable it is. So, with thicker shingles, youre going to need more bundles to cover your roof because the thickness means there are fewer shingles in each bundle.
Depending on the size of your roof and how many bundles you need, you may pay significantly more for thicker, heavy-duty shingle bundles. So its something to consider before you buy.
Whether youre doing calculations on your own or dealing with a contractor, weight and thickness are factors to consider before any work begins. Also, make sure you know how many bundles of each type of shingle youll need to cover the area you need.

What Is A Bundle Of Shingles
A bundle of shingles is one package of shingles. Shingle manufacturers will package their bundles so that several usually 3 or 4 will add up to 100 square feet. A bundle of shingles will contain anywhere from 15 to 29 shingles, depending on the type and size.
It is important to note that there is not a uniform number of shingles per bundle. The number of shingles in a bundle will vary tremendously depending on if you have typical 3-tab versus laminated or other specialty shingles.
A bundle can only be so big. They are designed so that the average person can pick them up and move them, so you will never have one bundle drastically larger or heavier than a bundle for a different type of roof shingle.
Initially, a bundle of shingles was supposed to cover one piece of roof sheathing 32 square feet. And three bundles would add up to 100 square feet. The advent of laminated shingles, which are much thicker than standard 3-tab, have created bundles with a total area that is less than the original 32 square feet.
Pick A Dumpster That’s The Right Size
Once you know how many square feet your roof is and the weight of its materials, you should contact a local company to secure a dumpster rental for shingle disposal. Part of what makes renting a dumpster a convenient option is that the company will deliver the bin at a scheduled day and time, place it close to the home to make disposing of the shingles easy, and pick it up when scheduled to allow the roofing crew to start work on your new roof with minimal disruptions. Because you’ve already calculated your roof’s square footage, you’ll use that to calculate the size of the dumpster you’ll need. You won’t need to put your shingles in a bundle, you can just drop them right in. Dumpsters are designed to hold specific tonnages, so you should give your dumpster provider the estimated weight to get a bin that can safely handle the weight of your shingles.

Headlap 1 Square Isnt Always Exactly 100 Square Feet
If youre hiring a qualified contractor for your project, then you dont need to worry about this, but if youre replacing your own roof you need to understand headlap!
Earlier we mentioned that a roofing square is equal to 100 square feet. While true in most cases, this calculation does not consider headlap.
What is headlap? Headlap is the overlap of a row of shingles on top of the next row, which helps protect against water penetration. Because of headlap, a square of roofing shingles never really equals exactly 100 square feet of roofing when you line all the materials up.
Put plainly as possible: one square of roofing is not 100 square feet exactly, but is enough to cover 100 square feet of roofing area. The materials themselves may, and often are, more than 100 square feet in total.
How Many Bundles Of Shingles Do I Need For 2400 Square Feet
You will need approximately 72 bundles of standard size 3-tab asphalt shingles or 96 bundles of architectural shingles for 2,400 square feet.
Thus, for a 2400 square foot gable roof, you would need 72 bundles of shingles plus 10% of ridge, starter and wastages. Thus, it will take 72 bundles of 3-tab standard size shingles to cover 2400 square feet roof. Thus, there are 72 bundles of standard size 3-tab shingles you will need to cover 2400 square feet roof.

Thus, it will take 6 bundles of 3-tab standard size shingles to cover 200 square feet roof. Thus, there are 6 bundles of standard size 3-tab shingles you will need to cover 200 square feet roof.
Plan For Waste Factor
The only roof that will generate no waste from cutting is that rare simple gable whose roof length is divisible by the 3-ft. length of a shingle. Other simple gable roofs will require cut shingles at the rakes. From there, the waste factor increases with every obstruction, such as a chimney, and with every hip or valley.
Laminated shingles typically generate less waste than three-tab shingles do because you dont have to maintain a cutout pattern, but its tricky to determine exactly how many square feet of shingles you will be able to salvage. Its best to plan your order using the same waste factor that you would use for three-tab shinglesat worst youll just have a couple of bundles to return.For a simple roof, I generally figure 1 percent as a waste factor. On a complex roof with open valleys, I add 5 percent and sometimes more. Theres no calculation you can use to determine the extra shingles youll need for waste. With experience estimating jobs, youll get a feel for how many extra shingles to order.
Waste is also generated when shingles are damaged, which is inevitable when youre moving shingles around a steep roof slope and some will slide off. You may be able to salvage part of the damaged shingle, but dont count on it. You can also waste shingles when you nail them improperly and have to remove them. You may drive nails too low in the exposure or fasten one off a control line.
