Internal Copper Gutter Minimum Slope

The modified details are discussed below.

Internal copper gutter minimum slope.

Table 8 1b shows the minimum recommended slopes using these special details. Most contractors tend to set the slop at one quarter inch per ten feet of guttering. With the exception of membrane roofs water from internal gutters must discharge into a rainwater head or to an internal outlet as shown in e2 as1 figures 63 a and b and figures 64 b or c see figure 3. So if you have a 25 foot section of guttering you should set the downspout end of the gutter 5 8 of an inch lower 1 4 x 2 5 5 8 than the other end.

Lower slopes are possible under certain conditions using modified details. Table 8 1a shows the recommended minimum slopes for various copper roofing systems using the details shown throughout this handbook. In general long straight runs should have joints spaced a maximum of 48 feet apart. This brings up another important rule to keep in mind.

E2 as1 8 1 6 1 requires all internal gutters to have a minimum 1 100 slope. Expansion joints may also be required at changes in gutter width or depth at corners and at end conditions. Working out gutter slope as a general rule gutter slope is set at 1 4 inch per 10 feet of guttering. With the exception of membrane roofs water from internal gutters must discharge into a rainwater head or to an internal outlet as shown in e2 as1 figures 63 a and b and figures 64 b or c see figure 3.

This means the downspout end of the gutter should be set 3 4 of an inch lower than the other end. E2 as1 8 1 6 1 requires all internal gutters to have a minimum 1 100 slope.
