Each elbow should
have 1 screw in the seam which is not showing, total unseen screws should be
four. Straps should have at least a 1-11/2" wall mount strap and 2
side screws on each strap. Two straps per down spout on 1 story. Two story
houses require 3-4 and up with the increase of height.
(see diagram 3b) All screws should be pre-painted. See diagram 3c
for improper installation.
Your downspouts should match the corner boards on your house. If the lower
portion of the house has brick, stone, or a different color wood, a 2nd color
may be required.
3. How many should I
Downspouts should be
every 35 ft or less depending on the length of the run. If you have a house with
lots of corners it's a smart choice to have them closer.
Remember the water has to run through the gutter and over a lump or bead of
caulking on every corner just to reach the downspout.
