Volko Supply has been
selling these hand made copper through wall scuppers from our
Garden City Park
location for over 60 years! Made from 16 oz copper, our scuppers
have soldered and crimped seams. They have stood the test of time and the elements.
These products are made with pride in the United States....they are actually
fabricated right here in New York! |
| These scupper boxes are designed to
be installed from "inside" the parapet wall. They are manufactured
with a 4" flange, so the drain is easy to flash into the existing roof.
On asphalt or built up roofs this can be as simple as some tar and fabric,
or using a self adhesive roofing or roofing tape along with some asphalt
primer. This is the easiest way to get
the water off of your roof and through your parapet wall. Water runs out of the tube, and
you drop it into a
standard commercial leaderhead or into a
fancy leaderhead.
Sometimes these scuppers are used for
overflow from the roof to supplement existing vertical roof drains.

This picture shows the size differences
in a 4x4, 6x6, and 8x8 copper scupper |
On the left is a through wall scupper
with flange, while the unit on the right is a
scupper with an outlet tube
attached. The first is an easier install, but will either spill out or
must drop into a leader head. The second is a harder install, but can
drain directly into a leader or through an elbow. |

NEED CUSTOM
COPPER SCUPPERS??

| A 5' long through the wall copper
scupper. This is being used to drain a flat roof through a mansard
roof. Note that the seam is fully soldered. It is also double
locked to ensure the drain lasts, and survives freeze thaw cycles common in
the North East.

our other custom work here! |

Getting water off of a flat roof should be
a priority for every building owner. More problems come from standing
water freezing and getting into seams, getting under flashings, and eating away
at the material. If you have any questions about flat roofing or roof
drains feel free to call us at our New Hyde Park or Port Jefferson
location.
The problem here is the flat roof has sunk
down below the level of the
scupper
drain. Either the scupper has to be lowered, the roof needs to be
re-pitched, or a vertical flat roof drain has to be installed.

HOW MANY ROOF
DRAINS DO I NEED?!?!?!?!
The answer to this question really is: it depends.
That being said there are charts to help you, as well as
common sense.
How is your roof pitched? If the water doesn't flow to
a drain, it will never leave the roof. Any direction water goes, it needs
an exit.
The table below shows how many square foot of roof different
size drains can handle at differing amounts of rainfall. Remember to
consult your local building code and inspectors.
Example: In New York the max rainfall per
hour is 5". At that rate, a 4" roof drain can handle 3,680 SF of roof.
REMEMBER THAT YOUR ROOF DRAIN IS
CONSTRAINED BY THE LEADER SIZE AS WELL!!
