How To Calculate Roofing Nails

Your roof is one of the most important structural elements of your house, and in order to complete a successful re-roofing project, a significant investment in both time and money is required. It is highly recommended you hire a professional contractor for roofing work, and it can be difficult to cover the costs of pricey mistakes.

If you are undertaking the project yourself, its critical to remember roof work can be a risky and potentially dangerous job. Anything you can do take fewer trips up and down the ladder to the roof lessens the chance of injury.

A simple bit of math when making your supply plan can help you estimate just how many roofing nails are needed for a roofing job. You will need to know the size of your roof, and then you will be able to calculate an estimate of how many points of roofing nails you will need to buy.

When you are planning out a roofing project, it is key to track how much weight they add to the roof, especially if you are working with an older foundation and framing. In order to have an accurate weight estimate, you will need to include the weight of the nails used to hold the roof shingles in place.

Roofing: Calculate The Number Of Shingles

Roofing is a very important part of your house because it protects it from water. Without a watertight room water would be allowed to enter and stream down the walls in your house. It’s essential that the roof is in the very best condition.

Pitched roofs are commonly weatherproofed by using shingles, and these are arranged so that they overlap one another. It’s important that you have the right number of shingles on your roof, because if you have too few then it won’t be waterproof. You will then need to go back to the store a second time to buy more. Ordering too many roofing shingles will waste money.

There are a number of calculations that you can use to work out exactly how many shingles you need to correctly cover your roof. These calculations aren’t scary because you don’t need to worry about anything you learned in school.

Step 1 – Calculating the Square Footage

The first thing that you will need to do is work out the size of your roof in square feet. This is very easy, as it’s simply a matter of measuring the length and height of the room. Multiply the length and height of the roof together to work out the number of square feet that you need to cover. Remember to work out the total square footage around the whole of your house. For a simple room this will be very easy. However for larger, more complicated shapes you will need to work slowly.

Step 2 – Working out Number of Squares

Step 3 – Work out Number of Bundles

How Many Roofing Shingles Do I Need

To estimate how much roofing material you need, such as bundles of architectural shingles or rolls of synthetic roofing underlayment, you need to know the total square footage of your roofs surface.

How to Calculate Total Square Footage of Your Roof

To find your roofs total square footage:

  • Measure the length and width of each plane on the roof then multiply length times width.
  • Add the square footage of each of the planes together.
  • Example #1: Shed Roof with One Roof Plane

    For example, this shed roof has one roof plane.

    Multiply length times width :

    A x B = 40 x 30 = 1200 sq. ft. for the total square footage of the roof.

    Example #2: Gable Roof with Two Roof Planes

    This gable roof has two planes.

    So to derive the total square footage of the roof, you would:

  • Multiply length times width and length times width to get the square footage for each plane.
  • Add the two planes together.
  • For example:

    • Plane 1 : 40 x 30 = 1200 sq. ft.
    • Plane 2 : 40 x 30 = 1200 sq. ft.
    • Plane 1 + Plane 2 = 2400 sq. ft. for the total square footage of the roof.

    The weight of the bundle is decided by the type and quality of the . Three-tab shingles are lighter than architectural shingles, and slate tiles are usually the heaviest type. The quality of the shingle can also influence its weight–a 30-year shingle is heavier than a 20-year shingle. A square of shingles is 100 square feet, and we will use the weight for a 1500 square ft. roof.

    800 – 1200 lbs.

    Estimating The Size Of Your Roof Surface

    Every roof is unique, of course, and the size and shape of yours will factor into the final weight of the materials you toss in the dumpster. Roofers typically measure surfaces in squaresone square is equal to 100 square feet. Have a 2000 square foot roof? Youve got 20 squares, and so forth.

    While the type of roof and the underlayment can affect the final weight, as a general rule, for asphalt shingles, you can estimate around 250 pounds per square for standard three-tab shingles, and about 400 pounds per square for architectural shingles. Remember, again, if you have multiple layers of shingles, you need to multiply the total amount of squares by the number of layers before you find the weight. For instance, a 2000-square-foot roof with two layers of shingles should be treated as 40 squares, not 20, because the weight will be doubled.

    Find The Area Of The Footprint Of The Roof

    To calculate a roofs dimensions, you need to measure the roof as if it were flat, then account for roof pitch, calculate square footage, and finally determine how many squares of material are required for the roof.

    The calculator above can handle all of this, simply enter the length, width, and pitch, and it will determine the size of the roof in squares.

    Start by measuring the roofs length and width in feet as youre standing on the ground. Remember that the length and width need to be found for the roof, not the house, so take into account that the roof overhangs the building.

    Then determine the area of the roof as if it were flat. Multiply the length by the width in feet to get the area measurement.

    What Do Roofers And Homeowners Think About Gaf Shingles

    Of the homeowners that love GAF, the common point of appreciation is how good the shingles look. After 10-12 years, in various US regions, many homeowners report that their roof looks very good, and that they get a lot of compliments from their neighbors on how well its holding up over the years.

    Many people really like the value of Timberline shingles and how easy it is to find them in local home improvement stores. They are not expensive compared to other more upscale brands, such as Malarkey, but offer comparable curb appeal. Also, homeowners note that price for Timberline is not significantly more expensive than for the 3-tab product, but they look much better.

    The shingles that were praised the most were:

    Timberline HD greatest number of positive reviewsTimberline ArmorShieldWoodlandSlateline

    One line that got very little complaints and a lot of positive feedback was designer Country Mansion shingles. However, they have been discontinued as of 2013.

    What About The Waste Factor Should I Order Extra Roofing Materials

    Are Roofing Nails Overrated? | GAF Timberline Shingles

    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.

    Additional Considerations And Costs

    • Roofs may have more square footage than your home, due to pitch and shape. This means you might need more materials to cover it than the total square footage of your house.
    • Algae can discolor your roof, and in some tropical areas, fungus may cause damage. You can invest in an algae-resistant roof that contains zinc particles to prevent its growth.
    • An roof will last between 15 and 30 years on average, but if you live in an area with very high temperatures, it will be closer to 15 years.
    • If your roof was damaged in a storm, have your insurance company send out an inspector to check the damage. If they and your roofer agree on the scope of the work, your worker will contract with the insurance company to pay for the new roof.
    • You can install a single layer of asphalt shingles over another layer of asphalt shingles one time without removing them. After this, both layers must be removed.
    • A new roof can increase the value of your home. The amount varies depending on the type of roof and the area you live in.
    • You need a permit to have a new roof installed. Your roofer should take care of this for you.
    • Architectural shingles cannot be roofed over because they are too thick.

    Which Shingle Is More Durable

    Durability is a very important factor, because you want your new roof to last a long time. GAF and CertainTeed have comparable quality shingles.

    Still, many roofers have their personal preference. This may be due to local weather differences, as well as particular installation methods of each roofer.

    In terms of pure facts, Landmark shingles weigh at least 250 270 lb per square. This makes them about 30% more heavy than Timberlines. Some roofers believe this extra weight makes Landmark more sturdy and less susceptible to wind blow off.

    They are also more resistant to cracks, cupping and heavy impact such as hail. One disadvantage is that the extra weight makes for a more challenging, time consuming installation. This can be one of the reasons why some less experiences roofers would not like Certainteed shingles.

    Other roofers think Timberline roofs are just as sturdy. The extra weight in the CertainTeed shingles is due to added limestone, which in their opinion is a useless filler material.

    Finding The Total Roof Area

    Once the area of the roofs footprint is known, the overall roof area can be found by accounting for the roofs pitch. The pitch of the roof is the rise over a 12-inch run. Use our roof pitch calculator to find the pitch of your roof.

    Next, multiply the footprint of the roof by the multiplier below for your roof pitch to find the overall roof area.For example, a 4/12 pitch roof that is 100 square feet:

    Calculating Number Of Roofing Nails To Buy

    I am putting on tar paper and then a single layer of 25 year 3 tab shingles onto my shed. It has 1/2 inche plywood sheething.

    What length of nail do I use?

    How many nails do I buy?

    Shed is 10 X 10 , Pitch is 5/12

    TIA :mrgreen:

    IF your talking gun nails then one box will do approx. 18 sq. and 1 1/4″ for lenght will be fine. hand bangs Probley 10lbs and 1 1/2″.

    Personally i like 1 1/2 to hand nail because there a little bigger and easier to hold and nail.

    4-5 nails per shingle. one box of coil. or 10 #’s of hand nails . 1 1/4″ is ok

    about 400 1 1/4″ nails,3-tab specs call for 320 per sq. walkable pitch,add another 156 nails for 6 nailing if it`s a high wind area,and approx.50 more for capping if necessary5-6 coils if gun nailing and a couple handfuls of handnails for the paper

    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. Which is 8 feet tall and I wouldnt hit my head on the nails but still it would look s h i t t y if nails were sticking out of the ceiling.

    How Many Nails Per Square

    Estimating your roofing materials is key to your success, so youll want to know how many nails youll use in a square. That depends on the exposure and coverage of your shingles. With higher coverage, youll lay down fewer shingles in a square and therefore use fewer nails. For example, when using Cambridge shingles, youll use roughly 240 nails, because of their Advantage size. If youre installing by the High Wind Application, youll use two more nails a shingle, so 360 nails per square.

    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.
