1 - at this point, the cut-up roof options will not be implemented fully, because of screen size limitations and technical issues. however we are brainstorming this for the later version update to the app.
I would need your guys input on how to better "present" these cut-up roof inputs. For example, issues we have with this so far:
There are different types of dormers - here is a most common one:
Technically, it does not add any sq. footage, but complicates the job a whole lot.
Another type of dormer, without sidewall flashing - basically it starts at the roof eaves:
There are too many variables to consider and input here, and in case like this, it would be faster to calculate it by hand.
Basically, this app should be a convenient tool for roofing contractors / estimators / sale-mens to quickly estimate almost any roof and to know your material and labor costs and to have a price-quote ready for the customer. The whole process should take a minute - not an hour.
We are not going to make a 3D-modeling software out of this app.
2 - Waste factor and MANY other settings will be available on special "General Settings" tab.
3 - Most of the variable you listed there, will be available through general setting or roofing materials profile settings (eg. 3-tab profile, 30-year Arch. shingle profile, Fake slate profile, etc.)
4 - You will be able to save and view calculation results and email the .csv file with the results. Results will not be saved automatically - only if you manually save the results. This may not be implemented right away, as we want to release the app soon, and features like this take long time to program. It will be available as a free update soon after release of Version 1.
