John Dirks Jr Posted July 27, 2007 Report Share Posted July 27, 2007 Do any of you measure roof pitch when doing inspections? I could see it being useful when determining if 3 tab composite shingles are being used on to low of a pitch. I know it can be done with a tape measure and a level but what do you think about this kind of tool? This one will also measure the pitch from under the eave. Do they have these things at Home Depot? http://roofgenius.com/roofangle.htm Quote Link to comment Share on other sites More sharing options...
Bob White Posted July 27, 2007 Report Share Posted July 27, 2007 I hope I'm OK with Owens corning on this: Print the following file. Cut it out and laminate it, or copy it to a transparancy.

Ms Simpson Posted May 7, 2009 Report Share Posted May 7, 2009 Depending on how crazy you want to get, there are gadgets that will measure from on top of the roof, from the heel, or you can order a Pitch Finder for about $6.00 online. Haageducation.com sells one, Illinois Lumber & Material has another (www.ilmda.com) I'm sure you can find others. They're plastic see-through cards with the pitch marked. You stand back and line up the roof to get an approximate angle. Good for quick and dirty. Quote Link to comment Share on other sites More sharing options...
Richard Moore Posted May 8, 2009 Report Share Posted May 8, 2009 I made my own when I started to measure pitches from the ground. I stopped using it fairly quickly as I found that I could eyeball a pitch accurately enough for the report in most cases. It's here if anyone wants it (works best on gable roofs).

gtblum Posted May 8, 2009 Report Share Posted May 8, 2009 I have one. It's called a framing square Quote Link to comment Share on other sites More sharing options...
SonOfSwamp Posted May 8, 2009 Report Share Posted May 8, 2009 I just measured a unit of the siding and/or brick, and counted up the X-inches drop of the roof, ridge to eave. Did the math in my head and that was that. I did that from the ground, because, don't you know, I just wasn't going to risk my skeleton.

Brandon Whitmore Posted May 8, 2009 Report Share Posted May 8, 2009 I use mine (from Home Depot) to check the slope of the roof more often to find out if the B vent is extended high enough, than to check for adequate slope for shingles. The one in Ed's photo is similar to the one I use. Quote Link to comment Share on other sites More sharing options...

StevenT Posted May 8, 2009 Report Share Posted May 8, 2009 I use this. I find, rather than holding it up to the roof and looking through it. I take a picture of the peak, and back at my office, I check the pitch. The sell very similar ones at HD. Click to Enlarge 30.55 KB Quote Link to comment Share on other sites More sharing options...
RobC Posted May 8, 2009 Report Share Posted May 8, 2009 I measure roof pitch if I suspect shingles have been installed on a less than 4:12 slope. I like to keep things simple, this is what I carry in my binder and its FREE. The amusement factor is priceless.

StevenT Posted May 8, 2009 Report Share Posted May 8, 2009 Hey Rob, That's pretty cool. I bet if you cut a slot in one end, you could use it to open bottle caps. Quote Link to comment Share on other sites More sharing options...

gwrichardson Posted February 21, 2011 Report Share Posted February 21, 2011 You can buy a pitch guage at Home Depot. The minimum slope for asphalt shingles is 2:12. Installing shingles on slopes between 2:12 and 4:12 require 2 plying the felt. That might be a little hard to visually check, but if you're doing destructive testing, you would want the pitch guage to check the slope.

In-Depth Posted February 23, 2011 Report Share Posted February 23, 2011 I have a level app for my smartphone that I use occasionally that shows slope/pitch. Jim Quote Link to comment Share on other sites More sharing options...
bruce816 Posted February 28, 2011 Report Share Posted February 28, 2011 I got this at one of the big box stores ie. Home Depot/Menards type Image Insert: 16.64 KB Image Insert: 21.51 KB Had this same one back when I was in construction. Threw it in my inspection kit and now I take it with me all the time. I generally use it on low-slope applications (similar to my forehead). Quote Link to comment Share on other sites More sharing options...
