The QUANTSPEC® estimator provides an estimate of  quantities for the complete roof system by answering a few, simple questions about shape and pitch. The ROOFSPEC® clause generator ensures your roof is built to the latest standards and guidelines by providing you with a document that you can pass onto your contractors which clearly outlines the requirements for the roof. The FIXSPEC® calculator provides a fixing specification based on the requirements of BS5534 and BS6399.
