How to Use the Roofing Calculator App – Guide for Roofing Contractors

As a roofing contractor you can make your job easier and faster by using a new and advanced Roofing Calculator App available on the Android Market and Apple’s App Store. The Roofing Calculator App will enable you to give your clients accurate information regarding size of the roof and cost of replacement, including a detailed break down of materials and labor costs within seconds. With this app, you will no longer have to worry about loosing a potential sale because you asked a client to wait for you to get back to them so that you can  complete the calculations for the estimate.

Roofing Calculator App is priced at $19.99 USD, and includes lifetime upgrades. We feel that the amount of time you save with our app is well justified by additional profits you make by selling many more roofs.

The App was developed by an experienced roofer, with a clear understanding of all the essential features and functions that other roofing contractors and professionals who work with roofs need to make their estimating jobs more efficient and precise. One of the biggest advantages of the Roofing Calculator is that it has a number of different modes, settings and profiles that enable you to easily customize your calculation based on the roof size and type, different types of materials, labor costs, waste and much more. The Roofing Calculator App is one tool that will significantly help you improve client satisfaction and give you an edge over your competitors so that you can sell more roofing jobs right on the spot.

How to use the Roofing Calculator App:

Two Convenient Modes – Roofing Calculator App offers two convenient modes: 1. Contractor Mode 2. Presentation Mode

Contractor Mode: This mode can be used by roofing contractors and other professionals who require detailed information about labor and materials costs in addition to the total price of the project. You have all the information you need at the click of a button to get a sense of the scope of the job, your costs and your profits.

Main screen

On the main screen of the Contractor Mode you will see different settings where you will need to input information to calculate the size and cost of the roof. You will need to manually input measurements for Length, Width, Roof Pitch and Ridge vent, as well as numbers of Skylights and Chimneys. You will have various pre-set options to choose from for Roof Type, Roofing Materials, Number of Floors, Roofing Difficulty, Roof Tear-Off, and Plywood/sheeting.

Results Screen

After you input all of the information and hit the calculate button you will be taken to a Results Screen. The beauty of the Roofing Calculator App is that it gives you highly detailed and accurate results that are broken down into three categories:

Prices: In this category you will get results for Total Materials Cost, Total Labor Price and Total Project Price

Materials Prices: In this category you will get a break down of prices of all materials necessary to complete the job that will include: Shingles, Underlayment, Drip Edge, Ridge Vent, Ridge Cap Shingles, Plywood, Miscellaneous.

Materials/Sizes: In this category you will get accurate values for: Roof Area, Waste (calculated as a %), Roofing Materials, and Length of Ridge.


Presentation Mode: We added this feature for situations when your client asks you to show them on the display how much the roof would cost – in this mode, they will see only part of the results that you would normally see  in the contractor mode. These include only TOTAL ROOF PRICE, and roof sizes!

We created this mode, because most homeowners only want to see what they care about most – the total price. If they get a glimpse into the contractor mode that has a lot of information about costs and charges for labor and materials, they will have a lot of questions and concerns that you may be overcharging them. You don’t want to raise these unnecessary concerns in your clients and you also do not want to spend your time and energy explaining  the fact  that as a contractor you also have dump / permit fees, overhead, and other expenses, which reduce your profits, compared to you your labor costs. Therefore, we made it easy for you to avoid the uncomfortable situations all together, and eliminated materials and labor costs from results screen in Presentation Mode!

Main Screen

The Main Screen of the Presentation Mode is exactly the same as in the Contractor Mode, requiring you to input all the information necessary for the calculation.

Results Screen

The Results Screen of the Presentation Mode is very different from the Contractor Mode and it is what you will be showing to your clients. They will see the following information:

Total Project Price for the roofing material that was selected.

Materials/Sizes: In this break down clients will see values for Total Roof Area, Waste (calculated as 5%) Length of Ridge, Length of Gables, and length or Drip Edge.

General Settings

By clicking on the Menu Button on your Smart Phone you can access General Settings. Here you can manually change the pre-set settings of the calculator to different values that you find to be appropriate for your purposes.These settings include: Number of Floors, Roof Difficulty (per sq.) Waste Factor (%), Underlayment ( Ice&Water or Felt Coverage), Skylight/Chimney Flashing, Roof Tear Off, Plywood/Sheeting (per sq). Simply click Done to save the information and make your future calculations based on the new values that you have put in.



Roofing Materials screen

Create your own Material Profiles – Roofing Calculator App allows you the ease and convenience of creating unique Roofing Profiles based on your own labor and material prices. You can access the Profiles Screen by clicking on the Menu Button on your Smart Phone and choosing to Add New Profile.



By creating these profiles you will save yourself a lot of time and hassle of having to calculate every roof from scratch. All the profiles that you create can also be edited and deleted.

If you are working with or know a home inspector or a real estate professional, you can boost your business and get more clients by recommending them to also use this app. To help a real estate broker or home inspector easily estimate roof replacement costs for their clients, you can pre-set values that you charge for labor and materials by creating different roofing profiles and also pre-setting the General Settings Screen. As a result, the real estate broker, or home inspector will be able to quickly give their clients an accurate roofing estimate that is already based on your own prices and refer them to you to get the job done.

  3. Hi Billy

    Dump fees can be added as Misc. At the bottom of main screen. You can also include the permits and other costs there.

    We will add a function so that dump fees calculate automatically depending on number of layers. But that will be for asphalt shingles only.

  5. Hi Kendall,

    We are developing the commercial flat roofing app right now. It will be very powerful, and will work for all single ply roofing systems as well as mod bit.

    As far as metal roofing – it will take some time for us to develope one, as there are many little things in calculation algorithm that have to be accounted for, and that can make a huge difference if calculated incorrectly. Basically we are still working on the calculation formula for that.

    Thanks for buying our app. Please rate it on the app store / android market.
