 There are some basic kinds of flat systems, each with specific maintenance requirements:

Built-Up Roofing

Often abbreviated BUR, this type is the basic tar and gravel roof. First, the felt that is treated with tar is rolled out on your roof with lots of overlap from one layer to the next. Then, hot tar is poured across the surface of the roofing and involves overlapping layers. BUR systems should last around 15 years. 

Modified Bitumen Roofing

This type is similar to a BUR design but utilizes a prefabricated roster that features modified asphalt or pitch with a rubber backing to improve functionality.

Typically, a BUR underlay is set up first and then the modified bitumen is implemented using an adhesive or flashlight. All these types are expected to last about 20 decades.

Ballasted Roofing

This system comprises a membrane system that is simply placed onto the roof deck and kept in place with stones or concrete pavers. The membrane and seams are sealed with an adhesive, and if correctly maintained then this type of roof may last upwards of 30 years.
