Our home is 4 years old, and we love it. We have standard size rain gutters without any covers. One nagging problem is that rain water often streams over the rain gutters located above the deck. This deck is surrounded on three sides by sections of roof forming valleys. The area has only one downspout, and adding another is not practical with the deck in the way. When it rains, the water often streams over the gutters, spashes onto the deck, and soaks the brick veneer and sliding door. The builder warned me that this would happen on occasion, but it happens a lot, even after I clean out the rain gutters.

Would larger capacity rain gutters help? Is there some creative storm covering that I could place over the sliding doors?

Thanks in advance.

 

If the overflow is occurring where the valleys drain into the gutter, deflectors may help.

Make sure the downspout you have is not clogged.

Otherwise, larger gutters and downspouts will be necessary.

If the deck is high enough above the ground, consider adding downspouts and drain pipes.

 

You say you cant put another down spout there. Id make that spout you have a 4 " one then and try it. If that dont stop it . Then just put a 6" gutter up there on the new 4 " down spout .

 

Good suggestions. Starting with a larger downspout makes sense.

 

Is the issue the gutters overflowing? or the run-off is over shooting the guttering?

It seems odd the builder would tell you to expect something not to work correctly?
