Gutters should drop a quarter inch every 10 feet in order to keep water flowing toward downspouts.
Poor slope gutters.
The standard slope for rain gutters is half of an inch for every 10 feet.
This means that your gutter should be a half inch lower in height at every 10 foot mark until you reach the downspout.
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.
Technically speaking the slope also called the pitch of the gutters is the amount by which the gutters slant downward along the path of the water flow.
An incorrect slope can cause substantial gutter system malfunction.
If gutters don t slope water gathers in them.
If gutters slope too severely they don t hold water and water could splash over the sides in heavy rain.
However for gutters to function correctly they require a slight slope called a pitch which causes rainwater to flow to the downspouts.
The gutter slope also called the pitch is the amount the gutter tilts down to let rainwater flow out of it.
If you can see standing water you need to re pitch your gutters.
The amount of collected water increases until it spills over the sides of the gutter.
Proper gutter systems divert the flow of water away from your home and direct it towards nearby storm drain systems.
Poor gutter drainage puts your home at high risk for water damage.
You can tell if your drain has a poor slope by looking in the gutter after a rainstorm.
