Adjust Gutter Slope
Measure the length of the gutter that you plan to adjust.
Adjust gutter slope. A gutter over 30 feet needs two downspouts. Next place a ladder at the left side of the house and measure from the roof down to the gutter. If your gutters don t slope then you only need to adjust the hangers and lower them slightly where necessary to achieve the correct slope. Multiply the number of feet by 1 16 inch to determine the total slope the gutter requires.
You can unscrew them or use a pry bar to remove the fastener holding the hanger in place lower it the correct amount and refasten. For example if the gutter is 16 feet long the end near the down spout must be 1 inch lower than the starting end. It should pitch from the middle toward the downspouts at each end. You want at least a quarter inch of slope for every 10 feet.
Start on the end of the gutter farthest from the downspout and measure the space from the roof edge to the top of the gutter. To adjust the slope of the gutter wearing gloves pop out the gutter pegs on the side and around the corners. Get on a ladder after a rainstorm and look in the gutter. This simple act can turn problem gutters into an efficient drainage system.
To correct this yourself you ll need to measure from the peak to the downspout. Use a hammer and crowbar to loosen the gutter. If there s standing water it s not pitched properly.
