Developed rooftop frameworks can be built in various ways. Frequently, the developed rooftop framework begins with a base sheet introduced over the protection or cover board, normally using mechanical clasp. The base sheet fills in as the base layer of waterproofing security for the rooftop framework and gives a surface that will permit resulting sheets to be stuck with hot black-top.

A layer of black-top is applied over the base sheet for the establishment of building up felt, some of the time called a utilize sheet. Many individuals picture pots of hot black-top being cleaned onto the base sheet to introduce the handle sheet, yet progresses in assembling have made elective choices. For example, project workers can decide to utilize cold-applied glue arrangements rather than hot wiping black-top and pots.

At the point when soaked in black-top or cold-applied glue, the supporting felt makes an obstruction that gives extra protection from water interruption. The interaction is rehashed with the utilization of black-top or cold-applied cement, trailed by the establishment of extra handles until the ideal number of employs is accomplished. The framework is then either covered with a mineral-surfaced cap sheet or finished off by covering the top layer with black-top and spreading rock or slag.
