With its trapezoidal lecture hall expressed as a massing element, the
Mathematics Building at the University of Colorado is a distinctive
structure on the Boulder campus. Unfortunately, the intersection of
the angled walls with the clay tile roof resulted in poorly executed
roof flashing details. Working with the University's project manager,
we investigated the existing conditions and designed new flashing
details. The clay tile was removed to allow for the installation of
new pan flashing and the tile was reinstalled.
