Measure from the roof edge at both ends of the gutter if you want to be sure.
How do i change the pitch of my gutters.
Test the pitch of your reinstalled gutter by turning on a garden hose and directing the water into the farthest part of the gutter from the downspout.
A good guideline is that the pitch should cause a decrease somewhere between 1 to 2 inches over a 40 foot run.
Watch the water to ensure it begins to flows down toward the downspout.
The gutter should have a quarter inch of slope per 10 feet.
Pull the gutter down about 3 quarters of an inch lower than it originally was.
Put a temporary screw at the back to adjust the pitch.
Once the gutter is properly pitched re install the gutter brackets.
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.
If gutters don t slope water gathers in them.
The gutter slope also called the pitch is the amount the gutter tilts down to let rainwater flow out of it.
If you d prefer you can hire someone to do the job for you for between 50 and 250 depending on the size of your house.
The amount of collected water increases until it spills over the sides of the gutter.
If you don t have a garden hose you can test the pitch using a bucket of water.
