With Built-Up roofing
systems, the highly reliable waterproof membrane is
field fabricated with layers of bitumen, alternating
with plies of reinforcing felts. The redundant layers
give it exceptional resistance to water and weather.
Started in the
1840's, these roof systems are often referred to as "tar
and gravel" roofs. BUR consists of multiple plies of
roof felts laminated together with bitumen. BUR consists
of bitumen-saturated organic-fiber, fiberglass, or
polyester felt. A top-surfacing or a glaze coat of
asphalt, aggregate (gravel or slag), fibered, or
non-fibered coatings engineered for roof coating, or a
granule-surfaced cap sheet.
Built up Roofing
BUR may be designed and specified to meet a broad range
of building waterproofing applications, depending on the
needs of the building owner. These systems range from
very basic systems designed to be vigorously maintained
to upper-end systems that are constructed to qualify for
a manufacturer’s warranty. Roofing manufacturers,
working in close coordination with our roofing experts,
will write long-term warranties for building owners
based on specific design criteria.
Over the years, BUR
has earned a great reputation with building owners,
architects, engineers, roofing product manufacturers and
commercial roofing contractors. The original cost of a
BUR system may be greater than other low-slope
applications, but when taking the long view, BUR often
comes out a winner. BUR enjoys a track record that is
over 150 years old, provides a thick, durable roof
covering, may be used in a broad range of building
waterproofing applications, and after many years of
service may be maintained and repaired for extended life
(many other systems must be completely replaced).
