    Default Roof to wall intersection flashing

    In my mind there is no way that this roof to wall intersection could be properly flashed. Does anyone disagree? I know that with stone veneer you do not always see the flashing details but with a brick veneer wall I always see the flashing at the intersection point. Feedback is appreciated.

    Did you by chance "tap" on the shingles to see if you could feel or hear any flashing under them?

    Regardless if it has flashing or not, it is wrong. The shingles should never be affixed or mortared into the brick like you are showing in the picture.

    It's too bad that when AD got banned, his good informational posts were erased. That roof detail is shown on the BIA.org website. Sorry, I don't have the time to post the link right now.....

    That detail is good when the masonry constructed chimney runs through a roof, what you see here is the brick venner up the cheek walls resting on the shingle. Typically in residential construction, they would bolt 3/8" angle to the framing, keeping it off the roof sheating by a inch when you have a lower elevation roof line by 5 or so feet. Unless they used a flashing bigger then the flat stock 5"x7", you will not be able to see it with the thickness of the brick unless you tap like Scott said and hear it.

    They would of needed a large kick out/ diverter flashing where the brick turned up that roof, that should of stood out.Not a accepted practice from the roof manufacturer. If they roofed the building and stepped flashed it properly with the lapped WRB and the mason bolted the angle over it keeping the painted angle a 1/2' off the finish roof surface, done... and install the correct kick out at the started course.

    It's tough to tell in the photos, but it looks like the brick was installed after the roof shingles, and the brick is sitting on top of the shingles. It might be an optical illusion, though.

    It also looks like the brickwork was recently installed (or repointed) based on the mortar on the roof shingles. I wonder if they were tring to hide something in preparation for the sale

    This was brand new construction and the buyer has already closed. She did not get an inspection before closing because as she told me, "everyone told me you don't need an inspection on a new house". She then had a problem with her garage door and a light fixture and after the builder dragged his feet getting back out to fix those issues, she decided to have an inspection done. I reported the flashing as improper and recommended a competent and qualified contractor. Here is another picture of the bottom edge. I could lift it up and see roof felt and decking. Not done right. Definitely no kick out flash. I did tap on the shingles but I really could not tell for sure... Thick shingles and they were literally mortared down flat... Thanks for all of the input.

    Your last set of pictures shows that it is wrong.

    Your client needs help. If this simple flashing detail is missing, I'm sure the home has many more problems. In TN the builder is on the hook for the first year for everything in the home and for 6 years for structural defects. Your client needs to use your report and needs to place the builder on notice that everything needs to be properly corrected. She may need to get an attorney involved to advise her if the builder is not being cooperative. Right now I'm working for 3 homeonwers who have filled law suits agianst builders who will not make good on their warranty. When times are tough promises tend to go out the window.

    AD banned? Not necessary. We crawl around in damp dark places and we are too thin skinned to take some abuse from a sarcastic know it all? I found him funny. I know I am really stepping in it, but bring AD back.
    I will probably have as much success with this as I had in making Mighty Mouse our national rodent to replace Mickey Mouse. When you do something wrong you say you "Mickey Moused it". Mighty Mouse on the other hand flies, sings opera, and kicks the %^$# out of Oil Can Harry.

    Shane,
    Good catch. That seam was going to leak, it was just a matter of time. The builder was probably relying on the upper soffit to keep the water from running down it, but then comes the wind...

    Here in New Jersey, our Uniform Construction Code (Administrative Construction Law Book) holds a builder/developer to code violations 10 years after a certifacate of occupancy. Since buildings are not bonded its our best law yet after that CO is issued.

    Any states with similar out there?

    It could be fixed, step flashing can be slide under the shingles. Cut grooves in the mortar with a grinder for the cap flashing. Probably less than a days work... only a few hours if done right from the start. Why not do it right from the start?
