Measure the pitch of your roof. Pitch is determined by calculating the vertical height of the structure over 1-foot--or 12 horizontal inches. For example, if your roof raises 7 vertical inches per one foot of horizontal length, the pitch measurement equals 7/12. Use this measurement to determine the type of vinyl gutter material you need.
Measure the overall length of the roof and the distance between the roof and the ground. Double each measurement to determine how much gutter and spout material you will need. For example, if the length of your roof is 12-feet you will require 24-feet in gutter material; 12-feet of material for both sides of the roof. If the distance from the roof to the ground is 10-feet you will require 20-feet of spout material; 10-feet per each side of the trailer.
Position the section lip of the gutter flush against the roof. Screw rust-proof nails into the prefabricated holes on the section lip as you secure each gutter piece together. If your roof has shingles, screw the section lip beneath the shingles directly to the roof. Use inside corner and outside corner connectors if your roof has any bends, as necessary.
Secure a metal gutter bracket hanger every six inches to the inside of the gutter. Hangers keep the gutter intact and prevent it from expanding or collapsing.
Snap end caps onto each end of your gutter.
Screw a 3- by 4-inch aluminum down spout elbow to the drop outlet.
Attach the down spout to the elbow and push it flush against the surface of the trailer. Screw the down spout to the trailer via prefabricated down spout strap holes.
Position a splash block under each down spout end.
