powerful bidDING and estimating TOOLS

Accurately estimate low-slope systems

Knowify has powerful built in templates to help you quickly and easily estimate a variety of GAF low-slope roofing systems. You input the basic characteristics of the roof and the roofing system you wish to estimate, and Knowify will provide an almost immediate list of the materials required. Have you ever underestimated the number of Drill-Tek™ membrane fasteners required for a mechanically attached TPO job? Or insulation fasteners for an adhered job? Or the rolls of GAFGLAS® ply sheets in a built up system? Knowify can help! We can also help you estimate labor, and the expected cost for different GAF NDL Guarantees!

Organize your budgeting, ordering, and tracking processes

Wouldn’t it be great if you could order your materials straight off of your estimating workbook… just click a few buttons and (woosh) out goes the Purchase Order, paperlessly, to your vendor? Wouldn’t it also be cool if you could schedule jobs and workers in the same system, and track timecards and materials ordered against your budgets in real-time?

Yeah: we do all of this! It’s powerful, real-time project management.
