Installation instructions for Bally buildings abutting
existing buildings
Note: Spend a few minutes reviewing this material before
you begin installing the membrane roof. Using Figure 8,
find the condition that applies to your installation.
Condition A applies when a long side of the Bally
structure abuts an existing building; Condition B when a
short side abuts, and Condition C when both a short
and a long side abut.
Condition A: Long side of Bally structure’s membrane
roof abuts existing building.
Note: If Condition A exists, follow steps 1, 2 and 3 below
before referring to material on pages 4 and 5.
1. The width of your roofing material will be 6" wider
than the width shown in the chart on page two.
2. Fold the membrane material back before rolling up
roof material. See Figure 9. Note: Tabs will run
perpendicular to building wall. (See Figure 9) Space
between building wall and existing building must be
flashed first. Perforated material is recommended to
allow circulation if Bally building is a cooler or freezer.
(See Figure 10) .
3. Included with the membrane roof will be two outside
corner pieces. (See Figure 11) Install these corners
before installing your membrane roof. Caulk first. (See
Figures 11 and 12)
4. On page 2, find correct chalk line dimension.
Complete installation of roofing material on ceiling
panels, following instructions on pages 4 and 5.
5. Flash roof material to building wall following Figure
13.
6. At corners abutting the building, make a horizontal
cut in the roof material. Fold material down. Follow
Figure 12.
7. Complete installation of termination bars and
caulking, following pages 4 and 5. Install the
termination bars on the short sides first.
Condition B: Short side of Bally structure's membrane
roof abuts existing building.
1. The length of your roofing material will be 6" longer
than the length shown in the chart on page 2. These 6
inches are added to the reverse tab side. See Figure
14. Note: Tabs will run parallel to building wall. (See
Figure 15) Space between building wall and existing
building must be flashed first. Perforated material is
recommended to allow circulation if Bally building is a
cooler or freezer. (See Figure 10)
2. Included with your membrane roof will be two
outside corner pieces (See Figure 11) Install these
corners before installing your membrane roof. Caulk

1. The length and width of your roofing material will be
6" greater than dimensions shown in the chart on

wall and existing building must be flashed first.
Perforated material is recommended to allow
circulation if Bally building is a cooler or freezer. (See
Figure 10)
2. Fold the membrane material back before rolling up
roof material. See Figure 16.
3. Included with your membrane roof will be two
outside corner pieces (See Figure 11) Install these
corners before installing your membrane roof. Caulk
