Field notes
The homepage organizes its tools across five project areas, from roofing and concrete to energy and comfort. In the roof example, users can adjust waste, choose bundles per square, add a second roof section and compare pitch scenarios; the page also lists sources including the International Residential Code, OSHA and EPA rules. The site says its tools run in the browser without sign-up.
