How Many Screws Will I Need For My Metal Roof

How Many Screws Will I Need For My Metal Roof? Easy Formula To Calculate The Amount Of Screws

The vast majority of the jobs that we sell are fastened at 24 on center . Therefore, we will base this answer upon 24 O.C. screw lines. If your screw lines are closer or further than 24 O.C. you can make some adjustments based upon this formula. We are also referring to these specific 36 wide panels: Corrugated, R Panel or PBR Panel, and 7.2 Panel or Western Rib.

What Clip Should I Use

Not all clips are alike. There are one-piece clips and two-piece clips. “One piece clips are typically only used on our snap-together profiles,” says Jeff Haddock, technical representative, AEP Span, Fontana, Calif. “One-piece clips are designed to allow the panel to expand and contract within the clip. This allows for unlimited thermal movement of the panel while still securing the panel to the substrate.”

Two-piece clips are often referred to as floating clips. These types of clips are generally used with mechanically seamed profiles. This is due to the clip being seamed/folded into the panel’s vertical leg. “Seaming it into the panel’s vertical leg prevents the panel from expanding and contracting like a one-piece clip would allow,” Haddock says. “A twopiece clip system includes the body of the clip and the base. The body is installed onto the male leg of the panel and the base secured to the substrate. The female leg of the next panel is installed over the male leg and seamed into place. This locks the clip into position requiring the main body and base to move independently of each other.”

Average Cost Of Materials For A Metal Roof

As described above, the average cost of materials for a metal roof is around $12.00 $13.00 per square foot, but that can definitely vary based on your area, the exact type of material you choose for your metal roof, and the idiosyncrasies of your property, and other environmental factors that impact the final metal roofing quote.

Installation and labor costs also make up a major component of the cost of your new metal roof, regardless of the type of materials that you choose, so take that into consideration when you are getting started on choosing a metal roof or any kind of roof for your home.

That said, knowing the average cost of materials for a new metal roof in the United States is an important starting point!

The national average for a new metal roof is $18,500 , but of course, that varies depending on the type of roofing materials, your location, and your property.

Standard Size Of Roofing Sheets

Whenever someone is looking to add metal roofing to their home, they are undoubtedly curious what size sheets metal roofing comes in. Its tough to say the exact size or length of the metal roofing panel because it differs from one panel to another depending on the metal, style, and manufacturers specifications.

Choosing shorter metal panels for your home may leave holes on your roof, which will be prone to leakages. They will not be energy-efficient and will not protect your house from harsh weather conditions.

On the other hand, if you choose metal panels that are too wide or too long, it will cost you more in labor and there will be wastage from some of the panels.

When looking at metal panels on the market, you will notice they come in different gauges like 22, 26, 24, and 29. The length and width also vary from one panel to another. You should know the precise measurements of your roof while purchasing metal panels. Knowing the correct measurements will allow you to choose the right size of metal panels for your home so that they cover your entire roof.

Here Are The 6 Most Common Types Of Metal Roofs Being Installed In 2020

To begin we will divide the types of metal roofing into two main categories, exposed fasteners and hidden fasteners. Exposed fasteners panels attach to the home or building by running a screw directly through the face of the metal roofing into the wood or metal purling below. A hidden fastener is how standing seam metal roofing is installed. In hidden fastened standing seam roofing the metal is attached to the building via a clip that sits under the metal. In this type of metal roofing the screws are not seen.

Two of the most common types of exposed fastened metal roofing and probably the most sold metal roofing in the United States are a 29 gauge, corrugated metal roofing for agriculture/residential use, and the R panel or PBR panel as its called for the commercial roofing applications especially on pre engineered steel buildings.

29 gauge corrugated metal roofing is often referred to as barn metal or pole barn metal. It is a very common type of screw down metal that is easy to install and easy to purchase at most lumber yards. It can span 26 over open wood purling making it a great metal roofing for post frame buildings. And while we dont recommend this type of metal roofing for houses, it is commonly installed in residential roofing applications.

The next two types of metal roofs well discuss are hidden fastened or standing seam metal roofing. Both panels are considered snap lock because of the way the metal pieces snap together.

Corrugated Metal Roof Costs

Corrugated metal sheets have a usual shape of repeated wavy pattern or rippled pattern throughout. A plain metal roof is strong and has a great life expectancy but a corrugated metal roof increases the strength-to-weight ratios which withhold perfectly in harsh weather conditions.

Corrugated steel panel roofs are the least expensive type of metal roofing, costing about $1.20 to $5.00 per square foot comparable to the price of asphalt shingle roofing. Average costs to install a corrugated steel roof would be from $10,500 to $19,500. You can choose from corrugated aluminium roofs, steel or copper roofs according to your needs.

Corrugated steel roofing panels are thin and lightweight, which means it can be installed over an existing roofing. This cuts down on the costs of removing old roofing. However, the quality tends to match the price, as these metal panels are vulnerable to leaks and rust.

How Do Roof Snow Guards Work

During a snowstorm, snow is deposited on rooftops and accumulates, creating what is called a snowpack. As the snow continues to pile on, the roof may be able to keep the snowpack on roof for a time, but as temperatures rise the suns rays will warm the snow and cause the snowpack to loosen. When this happens, gravity plays a role and the entire sheet of snow or ice is suddenly released and an avalanche occurs.

Installing snow guards on a sloped roof hold the ice and snow on the roof and prevent them from sliding off suddenly. The weight of the snow and ice is evenly distributed by the roof snow guards as it melts off and therefore preventing damage. This is not only important for public buildings but for residential properties as well.

Mechanically Seamed Metal Roofing Panels

Finally, lets looks at a few types of mechanically seamed metal roofing panels.

A mechanically seamed metal roofing panel is a type of metal roofing that has to be crimped or folded together after the metal roofing is laid. Each panel is crimped, creating a water tight seam between the metal roofing sheets. The major advantage of this type of metal roofing is its ability to be used in low slope applications like steel buildings or on other types of structures where the roof pitch is below a 3 /12. Common mechanically seamed metal roofing profiles include the 2, 138T, 238T mechanical and the trapezoidal panel. These metal roofing panels are most often found on steel buildings in commercial or industrial applications.

As you may have learned there are many different types of metal roofs, each with a specific use and application. That is really where metal roofing preforms, when the right type of metal roof isused in the right roofing application.

How Many Solar Panels Do I Need For My Home

Its no use installing just one solar panelyoull need more than that to reap the financial benefits of a solar panel system. While the answer isnt always so simple, weve put together some example cases to help you understand, at a high level, how many solar panels you need to install an effective solar array.

How Many Hours Of Daily Sunlight Does Your State Receive

The sunlight available to produce electricity varies greatly throughout the United States. Southwest states like California and Arizona get the most sunshine, while northeast states like New York and Massachusetts get the least.

However, you should not discard solar power just because you live in a state that isnt sunny. For example, New York only gets moderate sunshine, but it has very high electricity prices. Solar panels are worth it in this case, since they achieve high savings even with reduced production. Saving 750 kWh when you are charged 25 cents/kWh is better than saving 1,000 kWh at 12 cents.

After estimating how many panels are needed in your home, you can make better purchasing decisions. Keep in mind that you dont have to pay the full system cost upfront. Many banks finance for solar panels, and you can pay off the loan with the electricity savings achieved. Leasing solar panels is also a viable option, where you pay a monthly price instead of purchasing the system. Your local solar installer may offer several purchasing options, adapting to your needs.

What Are Clips’ Benefits

But clips do much more than attach panels and make the roof look nice. “Standing seam metal roof clips are specifically designed to interact with their corresponding roof panels to accommodate design loads, allow movement caused by thermal changes and minimize deflection due to friction,” says Duane Sailors, vice president of engineering and sales, BPD, a LSI Group company, Logansport, Ind. “Clips are designed to match the profile of the intended panel to allow for a nested installation. This nesting allows necessary movement as well as sealed seams and aesthetic appearance. It is important to understand the necessary movement is due to thermal influence: both interior and exterior.” “Standing seam metal panel clips are designed to enable dimensional change of the panel without fatigue of its fastening, allowing for the thermal cycling process,” says Cindy DeBellis, sales director, SFS Group USA Inc., Wyomissing, Pa. “They provide durability and protection from the elements as well as improved aesthetics as they are a concealed fastening system as opposed to through-fastened systems.”

What Is The Most Common Cause Of Metal Roof Leaks

The single biggest cause of leaks on a metal roof is due to incorrect fastener installation. Once you learn about screw placement we recommend that you learn how to install the fasteners correctly. Your roof will have thousands of screw penetrations and watching this video is the best thing that you can do to prevent roof leaks.

How The Calculator Works

To get the most accurate results, you will need to provide the exact building measurements and roof pitch.

Very Important Note: Before you order your metal roofing panels, you will need to get on the roof and physically measure its run, to the exact number of feet and inches. REMEMBER that the calculator provides only an APPROXIMATE length for your roof panels. If you do not measure the exact length of your roof run, your panels may come out too short or too long. If your panels are too short, they may be unusable. We are not responsible for the accuracy of any measurements on your part.

When measuring your metal roofing panels, always measure from the eave all the way up to the ridge line, and add at least 2 inches for drip edge and return lock.

Measuring your roof you will need to use a tape measure to get the width and the length of your roof. You will also need to calculate your roof pitch, and properly identify your roof type. Use the following guides, which will help you to accurately measure your roof:

  • Roof measuring guide learn how contractors measure and estimate roofs.
  • Roof Pitch guide learn how to measure and calculate roof pitch. Roof Pitch multiplier table is provided at the end of this guide.
  • Roof Types learn how to identify your roof type, and discover the difference between Gable, Hip, Mansard, Gambrel and Shed roofs.

Metal Roof Trims: What Kind of Metal Roofing Trim Do I Need?

We have our three main assumptions now how do those numbers translate to an estimated number of solar panels for your home? The formula looks like this:

Number of panels = system size / production ratio / panel wattage

Plugging our numbers in from above, we get:

Number of panels = 10,649 kW / 1.3 or 1.6 / 320 W

which gives us between 20 and 25 panels in a solar array, depending on which production ratio we use . 25 panels each at 320 W results in a total system size of 8 kW, which is right around the average for EnergySage shoppers looking for a solar installer. Tada!
