Trade tools
Trade tools that feed your quote
These are working tools, not toys: run your takeoff or draft your flashing here, then send the output straight to the CSA trade desk as the basis of a firm quote. The first tools cover roof sheet, screw, gutter and ridge quantities, plus custom flashing girths, folding schedules and lengths. More construction-supply calculators will be added as the catalogue grows.
Calculator 01
Roof sheet & gutter takeoff
Enter your roof dimensions and the calculator estimates how many roofing sheets, screws and metres of gutter and ridge capping your job needs. Use the result as your cutting list when you request a quote - the trade desk verifies it before anything goes to supply.
Use 10% waste for simple gable roofs and 15% for hip roofs with valleys. Sheet length includes a 75 mm eave overhang allowance.
