At a glance

A gutter system includes the gutter itself, end caps, miters (corners), outlets, downspouts, elbows, hangers, and extensions or splash blocks, and often gutter guards. Seams at corners and end caps, hangers and downspout elbows are the parts that fail or clog first.

Part	What it does	Common problem
Gutter	Catches water running off the roof	Clogs, sags, leaks at joints
End cap	Closes the end of each run	Sealant fails and drips
Miter (corner)	Joins runs at inside and outside corners	Leaks when the seal ages
Outlet	The opening where water enters the downspout	Clogs with leaves
Downspout	Carries water from gutter to ground	Clogs, separates, too small
Elbow	Bends the downspout around the house	Where most downspout clogs happen
Hanger	Holds the gutter to the fascia	Loosens, causing sagging
Extension / splash block	Moves water away from the foundation	Missing, too short, knocked out of place
Gutter guard	Keeps debris out of the gutter	Cheap types clog or trap debris

What fails first

On most systems it's the seams (corners and end caps) as sealant ages, the hangers as they work loose, and the downspout elbows, which catch debris. That's why seamless gutters, hidden hangers and properly sealed corners last so much longer.
