How do you calculate the cost of a sandwich panel roof from roof slope to gutter?
The cost of a sandwich panel roof consists of many items, although the rate for the panel usually attracts the most attention. You also need to calculate the actual roof slope, the cutting layout, the joints, the flashings and the crew's work. A detailed schedule allows you to compare quotes for the same roof and to see whether an attractive price omits part of the required scope. The length of the roof slope is measured in the direction of the fall, taking into account the eaves detail and the joints. The area of the horizontal projection may differ from it. On the drawing, also mark openings, skylights and points of contact with other elements. Do not automatically deduct them from the purchase, because an opening is often cut from a full panel.
