How to slope a gutter with false bottom.

For spans longer than 40 feet it s wise to have a downspout on each end and start the high spot of the gutter in the center. Then set the fitting on the bottom of the gutter and trace around it. Put a temporary screw at the back to adjust the pitch. Next place a ladder at the left side of the house and measure from the roof down to the gutter.

Ask someone to hold the gutter while you loosen and remove the gutter brackets or hangers. For example if the gutter is 16 feet long the end near the down spout must be 1 inch lower than the starting end. Cut a starter hole in the gutter with a chisel drill or sabre saw and nibble out the finished opening with tin snips. This means that your gutter should be a half inch lower in height at every 10 foot mark until you reach the downspout.

They re inexpensive and easy to install. Multiply the number of feet by 1 16 inch to determine the total slope the gutter requires. Less than 20. Use a string level to ensure the string is completely parallel to the ground.

Measure carefully to determine the best location for the outlet fitting. The standard slope for rain gutters is half of an inch for every 10 feet. Gutter extensions attached to the bottom of the downspout will discharge water well beyond the foundation. If you are using the brackets that screw on you will generally have a guy on each end to help hold the gutter while you are in the middle pushing up as high as you possibly can then set the screw.

How to determine gutter slope. First determine the location of each one of your downspouts. Measure the length of the string to determine the distance between the two points. The gutter should have a quarter inch of slope per 10 feet.

To calculate gutter slope attach one end of a long piece of string to the highest point of your gutter and the other end at the location of your downspout. The best way to calculate the slope of a gutter run before hanging it is to use a long string and a string level. Pull the gutter down about 3 quarters of an inch lower than it originally was.
