    Default Drip edge Flashing

    Would someone please enlighten me on what is required on new roof application with drip edge flashing. I see where the 2015 code mandates them but I also see new construction without them. So what is it?

    Thanks for any help!

    If you see new construction without it, then I recommend that you inquire with your local AHJ about what they require. Around here, the different AHJ's adopt, modify, and/or ignore the IRC as they see fit.

    If you choose not to decide, you still have made a choice.

    However i would always mention in any report the lack of drip edge, in the Carolina's if your roof is not steep you can pretty much guaranty that you will have sheathing damage without it!

    It is fairly common here in TN to find homes with no drip edge installed. However, that doesn't make it right and I call it out in my reports.

    Does the code in your area specifically require drip edge flashing? Does the manufacturer specifically require drip edge flashing?

    If not, then 'not having drip edge flashing' is not "wrong" ... "PPP", yeah ... (Piss Poor Practice).

    Depending on the TN town/city and their AHJ, it may be required and it may not be required. A simple call to the county/town/city AHJ would tell you real quick if it is or not required. All shingle mfg. recommend it but do not require drip edge flashing… I have a few jurisdictions around me that require it..

    Refer to manufacturer's installation instructions, if there is no drip edge, it will void the roofing material warranty GAF require a certified installers in California who must be State Licensed Roofers' , I recommend that a state licensed roofer certify that the roof will last 2 years which is the FHA minimum requirement.

    A roof with no drip edge is a sure way for to end up with a dry rot decking.

    It depends on how short the Roofers cut the overhang above the gutters and, how far below the edge of the sheathing the gutters were hung -if you can see daylight from behind the gutter, you need drip edge flashing. Lots of times, the edge of the sheathing is rotted because people won't get off the couch and clean their gutters. JMO
