AHI in AR Posted October 17, 2013 Report Share Posted October 17, 2013 I see some direct vent fireplaces constructed like this where brick is laid over wood framing to create a sloped roof. While I can't say I've ever seen it happen (yet) I have to believe that water seeping through the mortar joints will eventually rot out the waferboard, causing the brick to fall in on top of the fireplace. I typically recommend installing a metal roof when I find these situations. Have any of you guys ever actually seen a failure in a similarly constructed home?

Jim Katen Posted October 18, 2013 Report Share Posted October 18, 2013 Perhaps there's some bituthene or somesuch under the brick? Quote Link to comment Share on other sites More sharing options...
AHI in AR Posted October 18, 2013 Author Report Share Posted October 18, 2013 Jim, it's possible but doubtful. As I recall, these fireplaces started showing up around here about a dozen years ago. I was still building homes then as well as inspecting them. In new neighborhoods I can say with all certainty that the standard practice I saw was to build a wood-framed enclosure for the fireplace assembly and simply lay brick on the waferboard used to enclose the top. The home in the photo is 10 years old. With inspections, I have seen ONE home where I felt sure that a problem existed. It was on a concrete slab, and the MDF used as the "legs" for the mantel surround were puffy from moisture absorption. There was no other explanation other than leaks thru the brick that were allowing water to reach the slab. Quote Link to comment Share on other sites More sharing options...
Jim Katen Posted October 18, 2013 Report Share Posted October 18, 2013 In that case, those things are screwed. Quote Link to comment Share on other sites More sharing options...
Brandon Whitmore Posted October 19, 2013 Report Share Posted October 19, 2013 Wow, I thought that the contractor who did those only worked in my area. I've seen a few, and wondered what was done beneath the brick. Quote Link to comment Share on other sites More sharing options...
Jim Baird Posted January 15, 2014 Report Share Posted January 15, 2014 Wow!...think of the old pop song,..so strange, must be the season of the witch...never saw anything like this. Very strange. It leaks, what ever it is. Quote Link to comment Share on other sites More sharing options...

Click to Enlarge 56.17 KB Never seen that. Builders are too cheap around here to use brick for anything other than the front of a house-and that is getting less common. Water will seep through the mortar joints and is will behave like stucco since the brick and mortar are probably directly in contact with the felt. I know you said you have seen the brick placed directly on OSB, but can builders really be that stupid in your area? I would contact the Brick Industry Association and see if they have any input.

Eric B Posted January 19, 2014 Report Share Posted January 19, 2014 Have any of you guys ever actually seen a failure in a similarly constructed home? Brick sills come to mind. Quote Link to comment Share on other sites More sharing options...
AbsoluteInspector Posted February 24, 2014 Report Share Posted February 24, 2014 Ive never seen that in my area but I would imagine if there is nothing to seal between the brick and wood it will rot over time without a doubt and I would mention it for sure.

David Meiland Posted February 24, 2014 Report Share Posted February 24, 2014 Is there a direct vent wall terminal inside that brick structure, and if so, was any provision made for it to get outside air? Maybe there's a roof terminal... hopefully so. Quote Link to comment Share on other sites More sharing options...
