Gutters can also prevent your walls from rotting

By
Home Inspector with Structure Tech Home Inspections

While everyone thinks about gutters being one of the most important aspects of maintaining a dry basement, gutters can also play a major role in preventing water intrusion at the exterior of the home.

As water drains off the roof and hits hard surfaces next to the house, such as decks and patios, a lot of water splashes against the house in an unnatural manner.  Houses are designed to shed water from the top down.  When water travels up against a house or sideways, it can have a devastating effect.

One of the worst areas that I regularly find problems with is where a roof valley dumps water on to a deck, and the water splashes against a patio door.  This will almost always rot the door and  the wall around it.  When gutters are installed and maintained, this doesn't happen.

My inspiration for this post came while doing a home inspection in Eden Prairie on a nineteen year old house.  The home didn't have any gutters, and water drained down from the roof right on to the wood deck.  I noticed some tiny trees growing out of the intersection between the deck and the house, so I suspected there was a nasty mess behind the siding.  Click on the photo below for a larger version.

Tiny trees growing at deck

I told the buyer to have the wall opened up by a carpenter before proceeding with his purchase, so he could get an idea of the scope of the damage.  The buyer met the carpenter at the house, and was kind enough to send me a few photos of the wall with the siding removed.

Rotted wall sheathing

Rotted studs

That wall sheathing is severely deteriorated, and a few of the studs were actually mushy.  I'm certain that gutters would have prevented this entire mess.  This is just one more reason to install gutters.

Al / Carol - It's a lot better when they do :)

Tom - thanks!

Robert - that's pretty close to what my alternative post title was going to be :)

Donald - absolutely.  Gutters solve a lot of problems.

Jay - I never thought of it that way.  Great point!

The saplings were really the big tipoff.  I poked around with my awl, and the siding was quite mushy right at the deck level.  That's what made me get a little more agressive with my recommendation.

Reuben, I have seen more homes, OK, all older homes, without gutters of late... I recommend them to my clients.

Funny.  I've found that the older the house, the more likely it is that it will have gutters.

Reuben-  Is it possible water was entering from roof-to-wall intersection?  Lack of kick-out/diverter flashing?

I had buyers look at a home without gutters just yesterday.  One of the things on their to do list if they make an offer is to put them up.  Of course, around here, sometimes people have issues with ice dams & remove the gutters thinking it will solve their problem.  It just causes other kinds of issues.

Oh that pesky splashback, so true.  And gutters in our area can complicate things on the North Side especially, always something.

Joshua - I've seen that happen plenty of times, but that wasn't the case here; this was definitely caused by water splashing back against the house.

Christine - you're completely right.  Gutters have very little to do with ice dams.

Rene - yes, that splashback will definitely cause problems with the house.

Hi Reuben. Nice catch! Nice that the owners were cooperative as well!
As important as having gutters is cleaning them so the water can actually use them. With fall coming it's no easy task at times.

Not only do gutters help keep homes from having water problems but new gutters add to the curb appeal. thanks for the great post.

Reuben - That is a lot of damage to that home.  I'm sure the potential buyer was happy with your recommendations.

Great post.   This is such a common occurence. Homeowners just don't realize how important good gutters are!

Mike - no, not my preference either... but it seems to be giving those trees plenty of water :)

Bruce - definitely.  Clogged gutters are pretty worthless.

Nick - that's another point that I never even thought of.

Stephanie - I don't blame you for not wanting to clean your gutters.  That gunk that sits in them can get pretty nasty.

Christine - yes, he definitely was.

Donald - no, and unfortunately, most builders are completely omitting gutters in my area.

Ih Reuben, I didn't know that gutters could prevent that much damage. It is well worth the investment.

Reuben, What a  great post and with super illustrations.  More of our homes in this area need to have gutters installed.. especialy since we average about 50 inches of rain a year.  This year, it would not have mattered though.

Judi - I just don't understand people's hesitation to install them.  I was at a huge house on Thursday, and a contractor was out talking about excavating the soils all around the house and dampproofing the walls because of the basement water problems... but the house didn't have any gutters!  Start with the easy stuff... duh.

Joan - yeah, I was glad to get those photos :)
