Technical Bulletin #27 : Creating Materials Lists


Metal roofing systems depend upon precise flashing for their watertightness and long term performance. As a result, manufacturers offer a wide variety of pre-formed accessories. While these accessories can simplify installation, they also can make the creation of materials lists more difficult.


Most manufacturers will assist their customers with the creating of materials lists and cost quotations. The manufacturer needs to know the roof pitch, configuration, and dimensions. On complex roofs, supplying photos can also be helpful.


A good materials list will help to ensure that the project is bid correctly and it will also help in ensuring a smooth installation process. Contractors who create their own lists find it easiest to determine lineal footage of all roof components (eaves, valleys, ridges, sidewalls, etc.) and then use those dimensions to create a materials list. The field panels are best determined by the exact square footage with a scrap figure added in based upon the roof’s complexity and the type of panel that is being installed. For standing seam roofs, material needs can be reduced by carefully developing an accurate “cut list.” Most manufacturers do offer detailed instructions for determining materials lists, as well as training.
