Built Up Roofing...
Built-Up Roofing (BUR) (multi-ply) systems have a proven
track record since their origination in the mid 1800s.
The are the most common low-slope roofing. Using reinforcement
felts and asphalt or coal-tar, a multi-ply system (three
to four layers of felt with inter ply layers of waterproofing
bitumens) provides strength to resist rooftop stresses
and changing environmental conditions.
The System benefits are:
- The have a significantly lower life-cycle cost than
other systems;
- They have a time-proven history of success, often
significantly exceeding service life;
- A larger critical mass enables the roof to tolerate
surface punishment;
- They are easily and economically maintained and,
if necessary, repaired with conventional, time-proven
materials, thus extending service life.
- We can make a built-up roofing system Title 24 compliant
by adding a white reflective elastomeric coating on
the surface. This will also extend the service life
of the roof with minimal cost.
