Installing Gutters On A Flat Roof

Gutters are often installed level for appearance.

Installing gutters on a flat roof.

Gutters are often a viable option for flat roofs directing water on the outside of the structure to downspouts. This is normally inch allowance for every 10 feet of gutter. If a gutter run will measure longer than 40 feet 12 m the gutter should be positioned to pitch down from the middle aimed toward a downspout at each end. Gutters can also be installed to work in tandem with a scupper system.

Gutters should be attached to the fascia and run the entire length of the roof ending with a downspout. Before installing gutters on a flat roof there are some major things need to consider. Measure the length of the gutter and calculate the slope. They are mentioned as below.

Secure the rest of the hangers with 2 in galvanized nails or screws. Use needlenosed pliers to slightly crimp the elbow to fit into the downspout as shown. Hold another elbow against the house and cut a piece of downspout to fit between the two elbows. It is impossible to install an external drainage system on buildings with a flat roof therefore they are equipped with drain funnels however it will be necessary to take care of such a drainage system in advance so that even at the stage of building a flat roof it would be possible to provide special slopes to the drainage points.

Check for drainage in your flat roof. Secure the downspout outlet to the gutter with four pop rivets or screws. Mark the line with a pencil and fix the gutter to the sloped line. It is necessary to have a proper drainage system in your flat roof to drain off the rainwater.

This is very important if you are planning to make a gutter for your constructed flat roof home. Use hook hangers and screw them into the fascia boards every 18 inches or so. In reality a flat roof isn t fully level and flat roofs built for gutters should direct water to one or more sides where the gutters are installed.
