They are packaged in plastic or paper wrapped bundles designed to be light enough for a person to carry, so heavier shingles require more bundles per square. Typically, there are three bundles to a square; this applies to most three-tab strip shingles and some lightweight laminated shingles. Heavier three-tabbed shingles and laminated shingles may require 4 or 5 bundles to cover a square. There are 29 standard-sized shingles 12 in. You can measure a new or freshly stripped roof in two ways: the measurement method and the sheet-count method.
When you have a bundle or square count for the main roof area, you will then add additional shingles to account for waste, starter shingles, and extra shingles for hip and ridge caps. If all the roof planes are rectangles, you simply need to multiply the length times the width of each plane to get the square footage; then you will add up the square footage of each plane. Many times, the roof may be too steep to walk on without safety equipment, so you will have to do the estimate from the ground.
If this is the case, measure the length of the building at the ground level and estimate any rake-edge overhangs. Next, from a ladder, use a stiff, wide blade measuring tape to measure from the edge of the eaves to the ridge. If the sheathing is still exposed you can use the sheet-count method, which is sometimes preferred more than the measurement method.
This method is fast, and you can usually complete it from the ground. The caveat is you can use this method only on roofs sheathed with 4x8ft. Each of these panels is 32 sq. Thus, the square footage of one piece is 32 feet squared. Count up all the sheets on all sides of your roof. Add them up. Then account for half or quarter pieces on the edges and roughly add them up to make complete pieces. Another way to measure the square footage of your roof from the ground is to calculate the number of shingles — or tabs — to calculate the square footage of the roof.
This technique works best with standard, 3-tab shingles since each tab has a uniform length and width. To find the length of the roof, count the tabs starting at one end to the other. Next, count the number of tabs from the gutter to the roof peak. This answer will tell you the width of your roof. Then multiply the length and width for the square footage of one side of your roof. Multiply times 2 for the total square footage. This method also works with a hip-style roof.
Remember that the square footage of a triangle is measuring the base times height, then dividing that number by two. Calculating either side of the hip roof is trickier, but one method is to measure the top and the bottom, then take the median of that number before you multiply by the width of the roof.
If your roof is L-shaped or a more complex shape, then you might consider another method, such as getting up on your roof and measuring each section yourself. However, the vast majority of shingles require only 3 bundles per square feet. Shingles with 4 bundles per square will require you to purchase bundles for a square foot roof.
Once you have the square footage, divide that number by This will tell you how many roofing squares you have. At the very least, using a shingle calculator can help you check your calculations. If you have a roof that has more faces than just two rectangles, a shingle bundle calculator will be more accurate and could save you money and time, ensuring you buy only the amount of shingles you need.
Therefore the length of one side of the roof is The pitch of this roof is Add a foot of overhang and you get 6. Multiply this by Multiply the two and you get Multiply that number times two and you get square feet — your total roof area. Now you need to find out how many bundles of shingles is required for square feet of roofing.
Divide by to find out how many squares of roofing you have. This equals 1. We know that each square of roofing requires 3 bundles of shingles, so 3 bundles of shingles times 1.
You still have. It would be prudent to purchase one extra bundle of shingles to ensure you cover your entire area and to replace any damaged shingles in the future. The roof pitch is , which means the width of the roof is about Add 1. The total roof area is square feet. Multiply 7. The number of bundles per pallet depends on the weight and size of individual shingles.
In most cases, there are between 33 and 42 bundles per pallet. Architectural laminated shingles are bulkier and physically larger; therefore, these pallets will have fewer bundles than 3-tab shingles. A bundle of shingles weighs anywhere from 60 to 80 pounds.
Most bundles are in the pound range. A bundle must be light enough to be handled by your average-sized adult. Therefore, you will not find bundles that way anywhere beyond 80 pounds. Very thick laminated architectural shingle bundles may weigh less if it requires 4 bundles to make a square of roofing. In that case, each bundle will cover a smaller area and will thus weigh less.
However, the majority of shingle bundles will have a similar weight. A standard bundle of 3-tab shingles is just above 60 pounds. Image source: Nobord.
If you're looking to replace your roof, you might be wondering: what kind of shingles are right for me? The most popular shingles on the market are asphalt shingles. Asphalt shingles are known for their durability, versatility, and low cost. No wonder they're the roofing material of choice in the United States! Even if you narrow your search down to asphalt roofing shingles, there are several different asphalt shingles to choose from. In this article, we break down the different types of asphalt shingles and what their best uses are.
Shingles cover your roof deck and roofing system to protect them from moisture. In North America, the most popular shingles to protect your roof are asphalt shingles. Asphalt shingles get their name from the asphalt used to make the shingles waterproof. Before , you could choose between two types of asphalt shingles: organic-mat and fiberglass.
The matting in organic shingles was made from cellulose fibers, like recycled wood and paper. Now, shingle manufacturers only produce fiberglass shingles. Fiberglass shingles are easier to install than organic shingles and they cost much less. Not only that, but they are more resistant to the elements. Organic shingles are prone to warping and algae growth from retaining moisture, so they need to be replaced more often.
Because of this, the production of organic shingles ceased in The price of a DIY roofing installation is cheaper, but you should always consider having a skilled professional complete or inspect your roofing system, just to make sure everything is installed properly.
Asphalt shingles are usually the cheapest roofing material option. The cost of your roofing project can also be influenced by the brand of shingles you choose. The following table outlines some of the most popular asphalt shingles and their estimated prices:. Calculate the cost for asphalt shingles with our roofing calculator. Asphalt shingles come in three different designs: 3-tab shingles also referred to as three-tab shingles , architectural shingles, and energy-efficient shingles.
Let's take a closer look at each of these shingle types. Image source: Triad Roofing Services. In reality, it is only one piece of material that is cut to appear like there are three shingles.
Keep in mind, 3-tab shingles have shorter warranties and aren't as durable as other types of asphalt shingles. Architectural shingles are more aesthetically pleasing, as they add depth and dimension to a roof.
