does this appear to be an issue?

what would be a good way to smooth/flash this?

to me it seems like a problem due to it being like a water scooper from the side

thanks

No truer words could be spoken griz....

I'm amazed at how many times folks try for the "cheap or quick" fix when there is an obvious problem and "doing the RIGHT thing" seems to be just too much work or not even in the thought process.

Now where's Struble to really stir the pot when you need him? :laughing:

They BOTH need to be extended. The flat needs to be extended farther to the right and the sloped needs to come down farther over the top of it with some sort of membrane (maybe ice and water shield depending what's on the flat roof) behind both flashings. That is a TERRIBLE flashing job. If it's been that way for a while, they've probably already got some interior damage. Whether they see it yet or not.

I don't think that could easily be patched with something that would give you/them a long term solution. It should be torn out and done right.

awesome responses

a concern is that this is at the bottom of a 20 ft long piece of bolted flashing

so, would it be necessary to remove the entire length of bolted flashing? (and then replace with new bolted flashing or staircased cut reglet flashing which would be alot of work). bolted flashing is not as good as cut reglet approach but 20 feet is quite abit of reglet work.

can existing bolted flashing be extended without extensive surgery?

thanks

You would need to remove both pieces of surface mount counter flashing. the one on the modified roof and the one on the standing seam roof. Then remove the last standing seam panel next to the wall. I would question how far up the modified roof goes up the slope. If they can't even install enough flashing... Anyway check to see if the modified roof goes up the slope (under the panels) atleast 8" We generally like to put at least 12" - 24" in this case of the repair you may not be able to get it up that high. If its not at least 8" you would need to add another piece of modified there. Then extend the modified flashing. Then reinstall metal panel and counter flashing.

I would not skip a step on this, its likely the owners or who ever are tired of having problems and if you say you can fix it for ***X.XX you damn well better otherwise they will be coming after you. Good luck :)

Ok, if you seriously want to know. Muck and fab is a repair that is common on flat roofs. It's a cheap fix that will last about 5 years if it's done right. It isn't something I'd use on roof that can be seen but a lot of "handymen" do. This isn't a recommended procedure. Doing this is like covering a car window with a plastic sheet, it will work but it isn't right.

Dope and Rag, mastic and membrane, or what ever else you want to call it, is absolutely the worst thing you can do to "repair" this problem. It will only cause more of a problem and a messy head ache later on for someone to deal with.

With that being said a Mastic and Membrane repair is perfectly fine on a older roof that doesn't have much time left. Again it needs to be done correctly like anything else.
