Metal Panels And Tiles

How to Measure the Square Footage of a Roof

Once found mostly on commercial and farm buildings, metal roofing is now the fastest-growing residential roofing material. There are two basic kinds: standing-seam panels and tiles. Panels come in pieces around 16 inches wide and up to 20 feet long, so they reach without a seam from the ridge to the gutters. Metal tiles can mimic the look of wood shingles or shakes.

Benefits: Extremely long-lasting some come with lifetime warranties. Good fire resistance, and some styles are strong enough to resist wind and heavy hail. Panels go up quickly and require little maintenance.

Drawbacks: Higher initial cost than composition shingles. Tile roofs have numerous grooves that trap leaves, so they need frequent cleaning.

Green factor: Styles with reflective coatings reduce cooling demand by 10% to 15% and can qualify for a federal energy efficiency tax credit of up to $500.

Cost per square foot: $3.50-$11, installed

Average two-story, 2,300 square foot house, including removal of one layer of roofing: $16,800.

Cost To Redo A Roof With A Different Type

If you are replacing your existing asphalt roof with a roof type that is heavier, like slate or stone tiles, the potential exists where you may need some structural reinforcement for the rafters and joists in the roof framing structure to support the additional weight. The reinforcement alone will average between $500 and $1,500 depending on the size of the home and the amount of reinforcement needed. Add the cost for your chosen roofing material plus labor on top of that.

Metal Roofing Cost: What To Expect

So how much does a metal roof cost, actually?

As of March 2021, you can most likely expect to pay between $8.50 $16.00 per square foot of metal roofing including installation, or $850 $1,600 per square in roofing terms, a square or sheet refers to 100 square feet of roof or a roll that is designed to cover 100 square feet of roof.

So, you can calculate the cost of your potential new metal roof per square foot based on the size of your roof and the price per square or metal roofing price per sheet.

Of course, this sizing is somewhat approximate so you will need to give or take a bit, depending on your property and any architectural details like skylights or unique spots that you need to account for so always check with your roofing contractor and make sure that the particular type of roofing they are working with is ideal from their perspective and if there might be any additional costs.

The price of a square depends on the type of metal roof that you end up selecting for example, metal shingles typically cost between $10.50 $14.00 per square foot including installation, while standing seam metal roof costs tends to be slightly more expensive, costing between $12.00 $16.00 per square foot on average.

Also, be aware that you may need to cover the costs of removing and disposing of your old roof .

How Big Is My Roof

How Many Shingles In A Square Of Roofing ...

Alright, lets start with the basics. First, you have to determine the size of your roof. Roofs are measured in squares. A square in roofing terms is equal to 100 square feet. The average home is approximately 30 squares, meaning that their roof is 3,000 square feet. Here is a simple way to figure out the measurement of your roof.

First, you need to find the square footage of the base of your home. Use a tape measurer to find the length and width of your home. If its irregularly shaped, divide the home into geometrical shapes, find the area of each, then add them together. Once you know the square footage of the base of your home, find the pitch. Youll see directions to finding the pitch of your home in the section below.

Now, youll need the pitch and square footage to find the size of your roof. Look on the chart below for the correct multiplier that matches your slope. Youll see that a pitch of 6/12 has a multiplier of 1.12. To find your roof size, multiply the square footage by the proper multiplier. The total is the total square footage of your roof!

Roof Installation Cost Factors

There are many things that make up the price to install a new roof in addition to the material choice and labor costs. Additional materials such as underlayment, venting, flashing, trash removal, and permits are often required for an installation and add to the cost. There are some other factors that may affect the price of installation to be aware of.

Steep roof pitch: A steep roof pitch can add to the cost of installation as it will be more time-consuming to work on a steeper pitch. Depending on the pitch additional equipment may also be necessary.

Complex roof architecture: A complex roof architecture is more time-consuming to complete than a simple flat roof due to angles and fitting. Complex roof structures also require additional flashing, adding to the total cost.

Tear-off of old roof: If you need to have an existing roof removed prior to installation expect to pay an additional $100-$150 per square to have the existing shingles removed. This may be a necessary step depending on how many layers of existing roof there are.

Roof deck repair: If the existing roof deck is rotten or damaged it might need to be repaired or completely replaced which could add to the expense of the installation.

Skylights and chimneys: Skylights and chimneys require a bit of time to add flashing and prevent the area from leaking. This can add labor and material costs to the installation.

Shingle Roof Installation Cost

The total cost of installing a shingle roof consists of both material and labor costs. Labor is a significant factor and can comprise as much as 60% or more of the total project cost. So, for a job that ends up costing $12,000, at least $7,600 of that goes toward labor costs.

With labor, you may need to pay to tear off and dispose of the old shingles and underlayment. In some cases, it may be possible to leave the existing shingles in place and to install the new shingles on top.

    How To Calculate Number Of Roofing Shingles

    Fortunately, you don’t have to make a haphazard shingle estimate when planning for your roofing project: your roof size and chosen shingle type will guide the purchase process.

    Shingles are sold in prepackaged bundles, not individually. Roofing manufacturers take the guesswork out of how many bundles you need per squareit’s listed in the specifications of each shingle they make. The specs for any given shingle will tell you how many bundles make up a square, how many shingles are in a square, and even the approximate number of nails you’ll need per square.

    Often, three bundles of prepackaged asphalt shingles make one square, as is the case with the Timberline® HDZ Shingles. That said, the number of bundles you need can vary depending on shingle design. For example, five bundles of architectural asphalt shingles with artisan-crafted shapes, such as the Grand Sequoia® Shingle, cover one square. Once you know the number of squares of material your roof needs, check the shingle manufacturer specifications so you get your hands on exactly what you need.

    If you’re still deciding on the perfect shingle for your roof, play around with the GAF VirtualRemodeler. The free online tool helps you envision how different shingle colors and styles would work with your home’s style. Be sure to keep local building codes in mind as you weigh your shingle options..

    How Much Does A Metal Roof Cost

    That all depends on the type of roofing materials that you choose and the style of property, along with any other individual details that may make installing a metal roof more or less complicated.

    The cost of metal roofing per sq. ft. or the metal roof cost per square or the cost of a metal roof vs. shingles obviously makes a difference, but there are other factors including the aesthetics of your property, the amount of time you plan to spend there before you resell , and the energy efficiency of having a metal roof versus asphalt or wooden shingles.

    You should also keep in mind that the total cost of a standing seam metal roof or a metal shingle roof also includes the specialized labor required to install the metal roof as well as the raw materials, and this may be the reason why some homeowners choose shingles over metal roofing.

    For some properties, the style of the home and the climate of the area it is located in may mean that asphalt shingles or wood shingles are a superior choice.

    That said if you choose metal roofing systems of any kind whether you go with standing seam, copper shingles, zinc shingles, steel shingles, aluminum roofing, or any other kind of metal roofing system, you will likely benefit from their durability and longevity, heating and cooling efficiency, resale value for both the metal roofing materials themselves and your property as a whole, and overall pleasing visual appearance.

    Instructions For The Shingle Calculator

    Enter the approximate value for how many square feet the house has in the first number box.

    Select how steep the roof is. A 4/12 pitch is relatively easy to walk, an 8/12 is very difficult to walk, and a 12/12 is impossible to walk.

    Select the complexity of the roof. One roof line is simple, two to four roof lines is average, and anything over four roof lines is complex.

    Choose whether or not your roof is new or will have multiple layers to remove.

    Finally, choose what type of new roofing will be used.

    This calculator is only an estimation. It is not as accurate as measuring each roof plane and adding the square feet together. It does take into account for an average number of offsets and an overhang. It also takes into account for the starters, the edges, and the ride caps. The squares returned include everything.

    The formula for solving for the area of a roof involves climbing onto the roof. Measure each roof plane. For shapes such as trapezoids, triangles, and trapeziums, find the average length by finding the center of the width. Remember to add two feet for valleys. Add the square footage of all of the roof planes together. Divide this by one hundred for the number of squares. There are three bundles of shingles for each square.

    To determine how many will be needed for starters and edges, measure the entire perimeter of the roof and divide it by three. Since there are twenty six shingles in a bundle of twenty year shingles , divide the result by twenty six.
