qhinspect Posted February 27, 2009 Report Share Posted February 27, 2009 I came across a house where the front of the house was sloped. The back part of the house was almost flat. I was wondering if you guys have any concerns about this transition or is this considered a standard practice.

hausdok Posted February 27, 2009 Report Share Posted February 27, 2009 I think it depends on where that TD ends under the shingles. It should overlap the ridge and then end on top of that second or third course of shingles before the last couple of courses are added on the shingled side. That way, any water pushed under the ridge will just drain out from under those top courses and onto the shingles below. That's a dumb chimney detail though; I hope they flashed that sucker correctly. ONE TEAM - ONE FIGHT!!! Mike. Quote Link to comment Share on other sites More sharing options...
qhinspect Posted February 27, 2009 Author Report Share Posted February 27, 2009 Thanks for the reinforcement of what I was thinking. I see the small strips that was applied on both sides of the chimney which makes me believe that it was applied under the roof shingles but cannot determine if it overlaped the shingles. I'm thinking it doesn't. Quote Link to comment Share on other sites More sharing options...
kurt Posted February 28, 2009 Report Share Posted February 28, 2009 This is a fairly common detail in our neighborhood. I see it often. What Mike said; the membrane should wrap over the ridge and on top of the field shingles, then the ridge caps it. The cap is decorative more than anything else.

You can't see anything that you can't tell from the attic. The Esquire sez so......... One other thing...... These suckers ice dam like crazy (but you probably already know that). The eave detail is critical; the membrane should be stripped and wrapped down behind the gutter, or some similar detail. Everyone wraps the membrane into the gutter, which will still back up water under the membrane. Quote Link to comment Share on other sites More sharing options...
Jeremy Posted February 28, 2009 Report Share Posted February 28, 2009 Kevin, How did you get that photo? From the neighbors balcony? My thoughts as well. I would think that a small parapet along the ridge might be better than the penetrations caused by nailing the shingles down over top of the membrane. I know, added cost... Is there any water staining underneath? Quote Link to comment Share on other sites More sharing options...
qhinspect Posted March 1, 2009 Author Report Share Posted March 1, 2009 I showed an owner of a well known union roofing company the pictures. He informed me from what he can see and for this application, he would considered this a standard installation. JeremyIs there any water staining underneath? There is only a small attic and not much to see. If there is ever a problem in the future, the first signs will be water stains or dripping from the ceiling. I personally don't like the way the roof is designed. There are other houses that have the same layout yet they just extended the roof higher so there is a slope on the back side. I hope the roofing company took extra steps to reduce/prevent the chance of water seepage. Quote Link to comment Share on other sites More sharing options...
