ASPHALTIC ROOFING
CASE STUDY 2
Mosaic Ultra Urban Living Apartments, Dallas, TX
Contractor: Texas Roof Management Inc. — texasroof.com
Building Owner: Hamilton Properties Corporation
Completion Date: December 2007
The Mosaic project involved renovation of
the former Fidelity Union Bank and Insurance
complex, two vacant downtown Dallas
office towers.
The renovation posed numerous challenges
including poor access between the 15 different
roof levels situated between the building’s two
towers; roof perimeters comprised of a gravel
guard edge, beyond which was a drop-off
at 230 to 410 feet to street level; and the
required removal of up to four layers of existing
roofing containing asbestos, coal tar pitch,
and fiberglass insulation. In addition, there
was inadequate drainage and severe ponding
water on every roof level.
Despite these complexities, the project was
completed on time, within budget, and with
no punch-list items. The new, clean, and
environmentally friendly modified bitumen
roofing system includes EnergyGuard
