We have finished the distribution system for the roofing calculator, and you can now implement it for free into your website – more details here: http://www.roofingcalculator.org/roof-estimating-software.php

If you need a custom programmed roof calculator with additional features and different prices, that relate to what you charge your customers to install a roof, as well as using Canadian dollars instead of US $, as well as meters instead of feet, we can do all that.

Simply respond in the comment box below, and we can go ahead and start working out the details and pricing for you.

It would be great if you can help us with figuring out the equation (I can estimate the weight, but not the volume and the size of the dumpster). I will think how we can integrate it into the calculator, and will add it in the next calculator update, which should be coming in the next few weeks.

BTW, the update will include the number of floors in the house which will affect price per square, as well as option for ridge vent, plywood replacement and other options and price adjustments.

Thanks for the great idea.

We can custom-program a roofing calculator for you in your currency and using meters instead of feet. Here is more information on obtaining a custom roofing calculator and installing it on your site – http://www.roofingcalculator.org/roof-estimating-software.php

I really like your application and think you would be able to benefit greatly by adding a field that determines how much the stripped roofing will weigh. Additionally, you could add a basic field that would recommend what size dumpster a consumer would need to rent in order to accommodate all of their waste. These numbers fluctuate but based on the number of squares, you can determine roughly what the materials will weigh and the cubic yardage. Please let me know if you are interested in adding this and I will be happy to figure out an equation.

We can definitely do something and create a custom roofing calculator, that would reflect roof prices in Canada (you would have to provide pricing structure, as I’m not too familiar with Canadian roofing market). This calculator would also be in Canadian dollars, and we can add custom functions to it, upon your request.

We will be improving our roof calculator very soon, adding new functionality and making the roof prices more accurate – possibly even include major metropolitan area selection for better accuracy. All this functionality can be implemented in your custom roof calculator.

Let’s discuss the details via email – info @ roofingcalculator.org (please remove the spaces – I added them to prevent spam)

I will also be emailing you the copy of this comment (from a different email address, which I normally use).

Sincerely, Leo

My son is in the roofing business in Canada and I am looking for a roofing calculator to add to my new and up and coming classified ad service like Craig’s list but much better. I am starting with the car section of the ad service but will be adding all the categories just like Criag’s List but much much easier to use with a search that will allow much more flexibility in the search process. I am looking for a partnership with the right group where I will advertise and promote their product through out North America….for the use of it here in Canada.

If you might be interested in talking about this please let me know and I am wondering what the prices per square are set at….and if they could be changed easily for Canada if we did some kind of deal…??

I am very interested but only for Canada even though my ad service covers the whole of North America…..every Province, State, Region and City…

If you would like to talk to me …please either send me an email or a number to call you and I will..

Thanks
God Bless

The we update the roofing pricing pretty often to reflect current state of roofing market.

Here are some things that limit the accuracy of the our Roof Calculator:

The roofing materials prices (mainly cost of roofing asphalt shingles) depend on price of oil. Shingle prices skyrocketed together with oil picking out at $140+ per barrel in the summer of 2008, but never really came down. Now they’ve stabilized more or less, but still there is constant movement.

Metal roof prices also spiked along with oil, but also did not come down much, and stayed VERY high for a very long time as manufacturers were sitting on expensive inventory, even when metal prices dropped more than 50 percent. Again these are more or less stable now.

The biggest factor which limits the accuracy of roof calculatoer is local economic conditions / natural (weather) conditions in each geographic zone. For example if a hurricane hits in Texas, roof prices there will spike, but will remain the same everywhere else.

As for economic conditions – local roof prices are usually directly related to local cost of living (unless there is abundance of cheap labor – usually illegal). For example, roof prices in Michigan are very low, as many people there (mainly those working for big three companies, lost their jobs). In Boston, roof prices are some of the highest in US, because cost of living in Massachusetts is very high.

Another factor is seasonal nature of roofing business. Although many roofers work throughout winter (http://www.coolflatroof.com/flat-roofing-blog/winter-roof-installation/), the average homeowner thinks that roofs are installed Mar. 1st through Nov. 30th. Therefore, competition increases in the winter as there is less work, and to get business, many roofers resort to lowering their prices.

Due to these and many other factors, the prices generated by the roof calculator are averaged. We are planning to implement a “Choose your State” feature, which would adjust roof prices to the geographic location, but even within a stat as small as MA, there can be huge difference in roof prices depending on how far from Boston you live. So it make averaging the roof price for major geographic locations pretty difficult and time consuming.

Please explain what you mean when you say “Maybe use Means as a guide”.

We are constantly fine-tuning the roof calculator formula, to make it as accurate as possible. Right now we are planning some major updates / improvements to the roofing calculator.

Thanks for the work you have done.
