CALCULATING GUTTER SLOPE
A slope of 1/4" (.25") per 10' run of gutter is recommended to ensure proper
drainage. To calculate the slope of the gutter for your building, take the building
length and multiply it by .025. Example below shows calculating the gutter slope for
a 20' building.
Building Length: 20'
Required Slope: .25" per 10'
20' (length) x .025 (multiplier) = .5" (Recommended slope is 1/2".)
5. Determine the gutter slope using the example to the right.
6. On the first end rafter, mark the height of gutter to indicate the high end.
Gutter position is between the ribbon board
for the drop-down or roll-up
side of the building and the 111613Z144
. (See diagrams on previous
page.) For best results, mount the gutter 3"-4"
above the ribbon board
for the drop-down and roll-up sides
.
7. Move to the low end and mark end rafter to set the required slope. Snap
a chalk line, or mark each rafter using a string line stretched end-to-end.
Use these to install the 113074 gutter brackets (if used) or the customer-
supplied 1" x 4" ribbon boards if the 113074 brackets are not used.
111613Z114
Ribbon board installed
with the main building.
Used for roll-up and
drop-down sides.
Step 6:
Mark
gutter position
(high end).
Step 7:
Mark gutter
position (low end). Mark
is X number of inches
lower than high end
as determined by the
required slope for the
length of the building.
Dashed line identifies slope
of gutter marked on each
rafter. Use marks to install
113074 brackets (if used) or
gutter ribbon board.
