What I'm Seeing Now

A Loose Ridge Vent Can Become A Long Leak

A ridge vent is exactly that, a roof vent at the ridge, and a loose ridge vent can become a long leak.

Not long in terms of time.  Long in terms of length!

The most efficient, and really the best in my opinion, is the soffit and ridge vent system.

Air comes in through the soffit vents, and finds its way out via convection and high pressure seeking low pressure.

It is pure physics.

It never fails.

The ridge vent is a cap, however, covering a long slit out of the top of the roof.

The slit is typically 3" or 4" wide, and nearly the entire length of the roof.

A ridge vent is typically installed with roofing nails.

If they are not long enough, or if they come loose over time due to winds and temperature changes, the ridge vent can come loose.

Often the ends will bend upward, but the entirety of the material can also come loose.

When that happens a LONG leak happens!

Ridge vent leaks are usually smaller, and happen over time. 

As such, the damage is insidious, slower, and the wood becomes more and more saturated.

That leads to rot and decay.

A ridge vent can be seen from the street.  If you need a closer look, get a good pair of binoculars and have at it.  Looseness is a problem that will only get worse, and is an easy fix for any roofer or handyman who wants to go up there.

My recommendation:  a ridge vent is an important feature on any roof.  It helps maintain the health of the roof sheathing and attic space environment.  Good attic ventilation contributes greatly to the longevity of the roof and the comfort of the indoor environment during the summer.  In the winter the ridge vent helps to carry off moisture, necessarily created by temperatures and day-to-day living.  Removing moisture is as essential as removing heat.

Thanks Debbie.

 Good Saturday morning Jay. Yes, I have seen this happen before. The sellers were not very happy campers. The company that had installed the roof was one of the storm chasers.

Michael - once I did an inspection where the storm chasers installed ridge vents on everyone's houses in a townhouse development.  Until my inspection nobody knew that they never cut a slit out of the top of the roof!  Fun and run!  Thanks for your check.

Good morning Jay. I have seen this too. Makes one wonder. Just follow the money!

I'd love to catch one of those guys in action.  THOSE  are the kinds of people I think should "give back."  The "give back" movement points at the wrong people.

Thanks for sharing this useful information. Water damage can definitely be a destroyer of roofs and knowing what to look for can help minimize the need for future $$$$ outlay.

Good morning Jay,

Yes the one where they installed the vent but never cut it out happened on this house; ended up with a tear off after only fifteen years of life!

Make yourself a great day.

The ones that get me is the ones like Raymond describes, they install the vent with out cutting the hole!

Raymond - see my comment #4!  And my follow up in #6...

Wayne - that's why we go up into the attic space!

Fred - see my comment to Raymond!  NOT uncommon, around here anyway.

Jay, I experienced this issues several years ago.  I happened to be in the attic putting some items away when I realized how bright it was and I hadn't turned on the lights!  I looked up and saw sunlight and thought that can't be good.  At least I caught it before it had a chance to rain.

Stephen - a large section of my neighbor's vent blew off and was flapping in the wind!  He didn't notice until I pointed it out...
