Introducing Roofing Calculator app for iPhone / iPad and Android smart-phones / tablets. This app helps contractors quickly calculate roof size, cost of materials, cost of labor, and enables you to provide your customers with a nearly instant price quote.

You will no longer have to run to the office to do a take-off or call your suppliers for current pricing. All materials prices and your labor costs will be saved in separate profiles, so all you’ll have to do is plug in roof dimensions, roof pitch and other details and click the “calculate” button – voila, you have your complete quote in front of you, including the cost of your materials.

Roofing Calculator App Features

The App will combine the functionality of our main roofing calculator and roofing materials calculator, as well as add a ton of customization options:

  • Roofing Materials Profiles – you can save your materials prices (including the cost of shingles, felt, I&W, roofing nails, ridge vent, drip edge, etc.) as profiles.
  • Chimney and Skylight Flashing – Set the price to flash chimneys / skylights.
  • Waste factor – Set the waste factor for Hip and Gable roofs, which we currently estimate at 7.5% for hip roofs and 5% for gable roofs.
  • Roof Slope – the tool will automatically calculate geometrical roof pitch, based on the pitch value you enter, and will provide the length of your gables / roof run.
  • Roof tear-off cost – you can set the cost to tear-off 1, 2 or 3 layers of old roofing materials.
  • Number of stories / floors – you can set a certain amount of up-charge for each additional floor in the house, as it costs you more to install a roof on a triple-decker vs. a cape house.
  • Total cost to install the roof you can set up your price per roofing square (your base labor price), and the calculator will add your cost per square for materials, chimney and skylight flashing cost, as well as other additional costs.
  • Roof Type – you can choose between different roof types (currently Hip and Gable roof) and the calculator will automatically estimate all your sizes and lengths for hips, eaves, rakes, ridge, etc., and apply the waste factor for a chosen roof type.
  • Roof Difficulty – Not every roof is the same, and it is much easier to install a roof on a straight-forward ranch, vs. a really cut-up roof with dormers, valleys, side-wall flashing, etc. You can set-up 3 different levels of difficulty: simple, medium and cut-up, and save in settings, how much to add per sq. for each difficulty level.
  • New Plywood – If you have to install new roof deck sheeting / plywood, you can set-up prices for 1/2″, 5/8″ or 3/4″ (really? :) ) CDX plywood or OSB sheeting.
  • Landscape and Portrait Mode – whether you prefer to hold you mobile device in one hand or with two hands, the calculator will automatically scale to fit the horizontal / vertical orientation of your phone


Calculator Updates

We are working on many updates. We are considering to either have separate versions of the calculator for flat roofs and metal roofing shingles and metal roof panels or shingles, or combining them into a single application with extended functionality.

All updates will be posted online in the Appstore and Android Market and you will be able to update your app for free (even if we add / extend functionality).

Adding more features – we will work on adding more features as time goes by. For example, one of the major updates we are working out right now is for the app to be able to calculate cut-up roofs with multiple valleys and dormers. However, these features will not be available in the release version of the calculator, as there are some technical / logistical and lay-out difficulties in implementing them on a small screen of an iPhone / Android phone.

We need your feedback!

As we are working on this roofing calculator app, we can only consider things that we think are important. However, each contractor / estimator will need some special set of features – that is where we need to rely on you to let us know what you would want to see in this app.

  1. I love your app. May I offer a few suggestions to make it better? First, in the state of MO. We require no license for our roofing business. I’d like to be able to omit the default implementation of the license on the PDF.
    Second, add drop down menu option to show material in square. For example, 3 bundles= 1 square or 4bundles= 1 square.
    Third, on the roof tabs in your app, I’d like to have the option to rename the roof tabs for multiple buildings at same address. (ex: Detached garage, goat barn, ect.)
    Fourth, have option to show box vents in estimate instead of just ridge vent.
    Last, add separate area on same estimate for a house that has both gables and hips.
    Than you for putting this app together. This app has lots of potential. I can tell that a lot of thought and work has been put into this.

  2. Hi

    I’m based in New Zealand and have some roofing clients who need an app to work on their ipads. Is your software metric capable?

    Thanks, Dan

  3. We just bought this app from iTunes today but it will not let me enter the length of the roof. on Section 1. I have deleted and re-installed and still cannot enter it.

    Is there something I’m missing.

  5. Hi I live in Australia and use the metro. System, I have down loaded this app and am unable to use it.

    Can it be changed to the metric system ??

    Regards

    Luke Allan

    • Hi Luke,

      We are working on adding Metric system to the calculator. However it’s not as simple as just changing units – we have to completely rewrite the formula, to adopt it to meters, so the measurements come out correctly.

      Quick question for you – what is the most common residential sloped roofing material in Australia / New Zealand?

      What do you typically use for rake / gable trim, and what is the length (exposure) of it?

      We will have metric system out soon (couple of months or faster).

      Cheers!

  6. hi, I want to purchase the app for iPhone/iPad. can you tell me if the standing seam option has been added? also, can we input prices in sterling instead of dollars?

    • Hi David,

      The standing seam has not been added – we will most likely have to make a stand-alone metal roof calculator app, as combining functions of asphalt shingles and metal roofing into one app my create too much confusion for the user, and certain errors in actual calculations, because of the way vertical panels are calculated, vs shingles.

      As for currency – my thinking is – if you enter the number (price) the currency symbol makes no difference – just assume the price is in your local currency. If we start adding options for this, we will need to include pound sterlings, euros, pesos, rubles, dollars, yuans, yens, etc. This is not a necessary option for the calculation accuracy in my opinion – so at this moment we have no plans to implement this function.

      What we do plan to add, is metric system calculation, along with imperial (feet / inches) currently used as default measurement units in US and consequently in our roofing calculator. I think many roofers in Europe and elsewhere in the world, will find this very useful.

      However, since I personally never worked with metric system, I have some questions to you (and other roofers outside of US):

      How do you measure roof slope? In degrees or in roof pitch?

      What is the default (typical) length of drip-edge metal? In US it is 10 feet. My thinking is that it is 3 meters in Europe.

      Are shingles sold in square meters? what is a typical price of an equivalent of 10 sq. m. of 30 years laminated shingles?

      Also – ridge vent length / price, ridge cap coverage per bundle (in meters).

      Any other discrepancies you can think of between metric and imperial measurements.

      Metal roofing in Metric system:

      How do you measure metal roof panel width in England? Our typical width here are 12″, 16″, 20″, 24″
      Ridge cap coverage is usually 6″ on either side.
      What is the height of the ribs on standing seam panels (ours is 1″ and 1.75″).

      This input would be most helpful for us to create an all-around useful roof estimating software for you guys.

      Sincerely, Leo

  7. @ Frank

    Entering squares will easy to implement, but the whole point of this calculator is that it also gives you complete measurements for all the trim and drip edge and ridge vent, etc.

    This can only be achieved by entering roof dimensions – otherwise how will the program know that you need 30 feet of ridge cap and 85 feet of drip edge, etc.

    As for printing results, we are working on it – please be patient – we want this feature to work well before we release it.

  8. I like the App but if there was a way to input Square instead of measurments of house… Also agree with being able to print. thanks

  9. I purchased the app for my iPhone. I’m impressed with is so far but am very dissapointed that there is no email feature where I can’t send to print. This would be a huge improvement. I could have a printer in my truck, send it to print, and have a professional estimate/contract waiting for me in my truck before I even get off the roof. I have another app that allows this but it is very basic and doesn’t have everything I need for a complete estimate. Am I missing something? If it can be emailed, I can’t find it. It seems to me that this simple feature would improve this up 100%. Thanks

    • Hi Roger,

      I wanted to let you know that Roof Calc v2 is available for download – please update.

      Now you can do up-to 10 roofs at a time! You can also save and export results. And many more things – all the way to sending your client formal proposal right form the calculator app.

      Please let me know what you think / what we can improve or add to make your job easier, and help you sell more roofs.

      Please also rate the app / leave feedback on app store / market.

    • Hi Juan,

      I will look into it. It’s a little complicated to do a full cut list for plywood – I think we will do just a number of 4×8 sheets based on roof size, rounded up to the nearest square, after waste. This will be the most accurate and simplest option I think.

      Leo.

  14. I like the app. But to better understand it can you tell me how each setting is formulated.

    Ie how much money is added for each dormer, or price per field squares.

    Thanks.

    • Hi Shawn,

      Prices per square are set in the roofing materials profile settings. You set materials price per sq. and labor price per sq. Labor is calculated based on the roof area, and for hop roofs, the app ads 5% for extra work. Here is a video walk-through of roofing profiles: http://www.youtube.com/watch?v=y5GpomRdPkY

      Materials are calculated based on roof area plus waste. Default waste factor is 5% for gable roof and 7.5% for hip roofs, and this can be changed in general settings. General settings video: http://www.youtube.com/watch?v=WD2Y_jQo2bg

      As for dormers – we are almost done with multiple roof sections update, which we will roll out soon. Right now you can use “roof difficulty” setting if your roof has dormers. Roof difficulty add-on (additional charge per sq.) can also be set in the general settings.

      Also here is what many roofers miss, and I did too, until I began calculating roofs geometrically (not by just using roof pitch multipliers and guesstimating) – dormers don’t really add any additional square footage to the total roof area. A typical 1 window dormer adds about 20-30 sq ft maximum, or even less. However, dormers are a major obstacle on a roof and take a long time to do. Therefore, a roof difficulty setting is a much better measure than calculating a dormer as a separate roof.

      What we will do, is add additional setting for small and large dormers (just like skylight or chimney flashing) where you can add a charge per dormer. Like I said – it barely affects your total roof size. For example, I measured a roof, with a HUGE dormer which was about 35 feet wide at the base, with 28 feet valleys. It added only about 130 sq. ft. to the total roof area, compare to the identical opposite side of the roof without a dormer on it.

      Look forward to the app updates. We will upload them as soon as they are ready.

      Leo.

  19. Hi Laura

    Release version will support metric system as well as feet / inches.

    App will have roofing material profiles, where you can specify all prices.

    We do not plan to have PC version – Mobile app only (Android and iOS). Android version will be coming in Jan, while iPhone version is planned for February, or possibly 1st half of march, due to possible development delays.

    Please read the development update of Android version of the app – http://www.roofingcalculator.org/roofing-calculator-for-android-development-report.php

    As far as “zinc and colourbond roofs” … what is colourbond??? :)

    Zinc – is it standing seam panels? We have not decided yet if we will have a separate version of a standing seam metal roof calculator, or combine it with the main version. It’s both a technical and a business decision, but so far, I think it will be just a single version.

  20. We are a plumbing business in Australia. We install zinc and colourbond roofs. We would love an application which helps estimate the cost of a job specifically for metal roofs. Preferably metric. We would need to be able to imput our own material prices and adjust labour prices. An application for the iphone would be ideal but also to download to our pc. Do you have a program which would work?
