Jerry Lozier Posted August 29, 2012 Report Share Posted August 29, 2012 please educate me on this: 5 year old home(s) whole neighborhood built the same. Hip roofs, can vents at ridge. I see no soffit vents and no space at eaves that might indicate venting right under laminate shingles. Attic was inaccessible to check attic for high moisture indicators or see daylight coming in somewhere near eaves. Can't believe they built a whole neighborhood like this unless they know something I should know. like maybe : 'we don't need no stickin vents system' your help would be appreciated....

Brandon Whitmore Posted August 29, 2012 Report Share Posted August 29, 2012 They probably omitted them. Code only requires 1:300 when there's a balanced system, and 1:150 when not. My guess- they don't have enough ventilation. Quote Link to comment Share on other sites More sharing options...
hausdok Posted August 29, 2012 Report Share Posted August 29, 2012 Is that a narrow gap I see just behind the fascia at the outer edge of that soffit sheathing? Is it possible that gap extends around the entire house and air is flowing in through that? Why no attic access? ONE TEAM - ONE FIGHT!!!

David Meiland Posted August 29, 2012 Report Share Posted August 29, 2012 I think that's a shadow from the flash... Quote Link to comment Share on other sites More sharing options...
Jerry Lozier Posted August 29, 2012 Author Report Share Posted August 29, 2012 All sealed up both edges of soffit. Yes that is shadow from flash. Thought maybe they had installed a 'SmartVent' under shingles, but shingles are down flat: no gap. Quote Link to comment Share on other sites More sharing options...
Rocon Posted August 29, 2012 Report Share Posted August 29, 2012 Where is the edge metal? Quote Link to comment Share on other sites More sharing options...
hausdok Posted August 29, 2012 Report Share Posted August 29, 2012 Where is the edge metal? If you're referring to drip edge flashing, nearly all roofers up here don't use it. Up until last year, if I were lucky, I'd see it on less than one out of every 100 houses. It's not required by the IRC and most roofers here say it's not necessary because we don't get a lot of snow (phooey!). Their answer here is to extend the edge of the roof about two to three inches into the gutter and let the heat from sunlight sort of bend the edge of the roof into the gutter and they call that a drip edge. I've written it up for more than 16 years and have been the butt of many jokes over it. ONE TEAM - ONE FIGHT!!! Mike Quote Link to comment Share on other sites More sharing options...
Rocon Posted August 29, 2012 Report Share Posted August 29, 2012 In discussions with the roofers, you could mention that it is funny that "drip? is not typically used regarding snow. Therefore, why would the presence of snow relate to the drip edge flashing? WA clearly has rain, which is very ?drippy?. I have a 1980 ARMA manual requiring drip edge.

tybertown29 Posted August 29, 2012 Report Share Posted August 29, 2012 The only other option would be if they did spray foam insulation up on the inside of the roof sheathing. Thus making the attic space actually part of conditioned space and thus eliminating the need for venting. It is pretty expensive to do, not likely but an option.

John Kogel Posted August 30, 2012 Report Share Posted August 30, 2012 I've never seen anything like it in a new house. Guilty of inadequate ventilation unless proven innocent. Jerry, let us know if you find out more. That looks like a huge attic space. Quote Link to comment Share on other sites More sharing options...
