Gutters need a slight slope so that water will flow out of them and not create pools of water.
Attaching gutters to vinyl siding.
Most vinyl siding is made to imitate wood lap siding so the lap of the siding is measured at the bottom of the simulated wood panel where the real wood would overlap each other.
All fasteners must be able to penetrate a minimum of 1 1 4 32mm into nailable material such as wood sheathing and framing fig.
Add a small elbow and length of downspout to direct water away from the side of the house.
Step 2 place a downspout strap at the top where it meets the elbow.
Secure one end of the strap to the siding with a zip screw and a cordless screwdriver with 1 4 inch socket attachment.
Trace around the downspout.
Aluminum trim pieces require aluminum or stainless steel fasteners.
How to fasten a downspout to vinyl siding.
Use aluminum galvanized steel or other corrosion resistant nails staples or screws when installing vinyl siding.
There are at least three alternative ways to do it.
Attach the downspout by screwing in a downspout hanger to the house approximately 3 to 4 inches above the end of the downspout.
Hold the downspout connector up against the bottom of the gutter and center it.
Remove any siding or exterior finish that isn t compatible with vinyl siding and make sure the walls are sheathed with a substrate to receive the siding.
1 2 inch 1 3 cm plywood or osb are common substrates and these are generally covered with roofing felt or another moisture barrier prior to siding the walls.
Step 3 add these two measurements together then add 1 2 inch.
Inspect your gutters and look for an area where a downspout would not be obstructed on its way from the gutter to the ground near the roof.
Fasten the downspout to the gutter elbow with sheet metal screws according to the manufacturer s instructions.
Attach the downspout to the hanger and the gutter.
