When is a vent a vent but not a vent? Not trivia, just the facts.

When inspecting homes for Desert Sun Home inspections in Carlsbad, New Mexico.

There seems to be one re occurring theme with builders and home owners that want to do the "Do it yourself jobs". More commonly known in the Real Estate world as the "DIY".

Any builder building a home today must know the codes. They should know how to build a home the right way.

So many times I find very little venting for the attic spaces. Next time you are talking with a builder ask them this.

"What is the free air space in square inches for that can vent you use"? This could be used for any vent they install in the home for venting.

I will guarantee that 99 out of 100 builders will say "I have no idea what the square inches of free air space is". Maybe they should visit this website that spells it out for them.

http://www.airvent.com  This is just one site of many available for contractors and home owners.

When vents are covered or obstructed.

This means the vent will not be as effective as a open un obstructed vent. As seen in this photo here.

Obstructed venting.Obstructed venting.

On this home every single one of the can vents were obstructed in one way or another.

The hole for the vent was too small and the vents were obstructed by a truss right through the center of the vent.

So the next time you have a home inspected. Mention to the inspector on how the condition of the attic venting is.

There are a large number of inspectors in my opinion that do not inspect for un obstructed clear air space.

I have asked a bunch of local bilding inspectors that tell me the same thing every time. They cite the codes. They know the codes. But when it comes to calling the codes out. They don't.

But isn't that their job?

This is why you always get a "Full Home Inspection" by a certified inspector. For the peace of mind.

HA!  It doesn't take a Rhodes Scholar to know that an obstructed vent isn't going to vent.

Hi Raymond,

As with inspecting. Those are mitigating factors when ever I try to get into an attic as well.

Have a great day in Rochester.

Hi Lenn,

At least not venting correctly. They will still vent, just not in the capacity they were intended to work.

Have a nice day in Loudoun County.

It seems that a vent, by definition, needs to be unobstructed Clint!  :)

Good post, Clint. Kind of off subject here but the inspectors in our area approved a house being built with the wrong set backs. So, last count...that was three different people that "inspected" the set back and decided it was okay. Turned out to be 8' off! How do these folks remained employed?

Clint, Some vent are more like ornaments.  Just got to wonder sometimes. Of course you could always just cut the the truss or rafter ;)

Clint-it almost seems like these vents were put in as afterthoughts. Not very well planned.

Clint: What is the use of having codes if builders are not going to be held to the standards...this has to be very frustrating!

Hi Tom,

So true. If blocked off then there is an issue. These are about 1/3 blocked.

Have a great day back from San Diego.

Hi Donald,

As you know cutting the rafter would take more work. How about just placing the vent correctly? What a concept.

Have a great day in the Great Northwest.

Hello Adrian,

That was a thought. Never seem to be installed correctly or even cut out correctly or... the list goes on and on.

Have a good evening in the Seattle areas my friend.

Hi Anita,

Then I become the bad guy in this situation. I tell the buyer the buyer tells the agent the agent tells the owner the owner calls the contractor and say's....Your inspector is off base on this one. The vents are right.

Have a good night in Warner Robins.

Interesting post. Hard to believe that most builders and inspectors aren't aware of what could be a huge problem. Thanks for sharing!
