Our calculator uses the following criteria to calculate the most accurate price for your roof replacement project:
1. Roof size

3. Number of chimneys and skylights
4. Roof complexity
5. Your region
You can select to get prices for multiple materials: Asphalt Shingles, Metal Roofing, and Flat Rubber Roofing.
Users can make up to 4 calculations for Free, which is enough for a typical homeowner. Roofing Contractors can unlock an unlimited number of calculations for $4.99
We can also make a custom app for your roofing business, with your own prices, logo, website, jobs portfolio, and custom contact / estimate form.
The images below are from both iPhone and Android versions. Note the second screenshot has “Visual Roof Slope” guide that is not present in the iOS version. This is due to limitations of how iOS displays the multiple selection carousel.
How To Use Roofing Calculator FREE:
Since both iPhone ad Android apps are nearly identical, using them is very simple:
To calculate the cost of your project, enter roof size (ground dimensions), slope, # of chimneys and skylights, roof complexity, and your region, and get your price quotes for for multiple roofing materials.
Roof Size: Measure the ground dimensions of your house with a tape measure, and be sure to add any overhangs.
For example, if your house is 26 feet wide (gable sides) by 42 feet long (front / back) and you have 1 foot overhangs on front and back and no overhangs on the sides, you should add 2 feet to the side dimension – enter 28 x 42 into roof size fields.
If you have 6″ overhangs all around, add 1 foot to each dimension (27 x 43).
Roof Slope: If you are unsure what you roof slope is, use visual help (images next to each slope setting, and chose the one that best represents your roof). Note, that this will only be available on the Android platform, due to the way iOS handles multiple selections.
Roof Difficulty / Complexity: This is a rather tricky concept, but to be on the safe side, assume that homeowners usually underestimate real roof complexity, while contractors sometimes overestimate it. However, roofers are the ones who will be doing the work, thus they know better how simple or complex the roof is. Therefore, if you think that your roof is between simple and medium complexity, choose medium. If you thing that it is more on the difficult / cut-up side, choose difficult. This way you will always be safe, and will not get a price estimate that is too low.
Skylights and Chimneys: Enter the combined number of skylights and chimneys.
Choose your region: Your local prices will be different than the National average, in some cases by as much as 18%. Our calculator is one of the most accurate tools on the market in terms of regional roof price differences. However, it may still be slightly off, if your city/town is way more expensive that the rest of your region, or if it is much poorer.
Finally click CALCULATE, and you will get a combined prices chart for 6 types of roofing materials. You can also request a free roofing estimate from local prescreened contractors, that are part of Roofing Networks.
