A roof is part of a building structure to cover the top of the building. It is the covering on the uppermost part of a building or shelter which provides protection from animals and weather, notably rain or snow, but also heat, wind, and sunlight.
Roofs are also designed as a warm or cold roof depending on how they are designed and built with regard to thermal building insulation and ventilation.

The initial cost of a roofing system includes materials, labor, overhead, profit and indirect costs associated with the structure.
The life-cycle analysis takes the first cost of the roof, then adds to it the future costs of operation and maintenance over the economic life of the roof.
The facility executive that fails to consider the value of a life-cycle costing approach to the purchase of a new roof does the facility and everyone involved with it a financial disservice. First-cost buyers may overlook such important future expense reduction opportunities as:
• Energy cost savings in the heating and air conditioning of the building through the use of white, reflective membranes or coatings and extra insulation.
• Extended roof service life for an optimally drained roof.
• Enhanced roof fire retardence and wind uplift resistance, resulting in reduced insurance costs.
• Extended roof service life resulting from the use of heavier structural framing materials, allowing a heavier roofing system.
• Future savings when the roof is to be replaced by using reusable roof component accessories.
