Roofgraf has been very accurate. I've been able to see exactly how much roof material is required for a particular job. So this has really helped with the budgeting process. I can also see the difference Roofgraf makes in roof area. The cost for Roofgraf has been an improvement over other software. This is helpful for getting more clients for a Roofing company. The software is very accurate and provides accurate estimations for every job. It has really helped the budget process, and I like that Roofgraf is user friendly. The app is easy to use, intuitive, well designed and available on almost all mobile devices. It's free of charge and always up-to-date. The only downside is that you can't draw directly on the map. Instead, you need to open a new page which is kind of annoying. But this shouldn't be something too important, I would say. It's perfect for roof measuring indoors. As it is really accurate, I have no complaints about this tool. It has been very useful when it comes to roof measurements.
