Leaking Gutters

Gutters may leak along their length, at seams, at end caps, at changes in direction, and at downspout connections. No matter what material is used for the gutters,

leaks are most common at seams and changes in direction.

So here is some tips from

Leaks may be caused by:

? thermal expansion and contraction

? mechanical damage (i.e.. the impact of ladders)

? broken solder joints
? dried caulking or adhesive

? rusting or rotting of the gutter material


Check Seams-

  • Look carefully at seams and along the bottom of gutters ,
  • Look at changes in direction and at downspout connections.

Look for Resultant Damage

  • Leaks are easy to find during or shortly after a rain but may be difficult to identify if there has not been any rain recently. Staining or streaking may be helpful, but these may also suggest over­flowing gutters
  • Look for damage to fascia, soffits, siding, and landscaping that suggests gutter problems. This includes moss, fungus, peeling paint, and rot. On masonry walls, also look for efflorescence, spalling. and deteriorated mortar.


  • If looking at gutters from above, you may notice patching materials in the gut­ters. This usually indicates attempts to repair leaking gutters. If it is a scam prob­lem, the situation may be localized and minor. If the metal is rusted through, the gutters may be near the end of their life. Sometimes this patching will be on downspouts. Similarly, you can use the distance between the bottom of the gutter and the bottom of the fascia board to check the slope.

Typical Slope-

Many gutters are nearly horizontal, and while more slope is better, almost any slope will work reasonably well. An ideal slope of approximately 1:25 is never achieved because fascias are too short and gutter runs are too long to allow a gutter to fall roughly 1 inch every 2 feet. A slope of 1:200 (1-inch drop over a run of 17 feet ) is more typical, and it is acceptable if there are no low spots . Some gutters slope from a high point in the middle to downspout at either end. Either situations acceptable.
