New Boot installed correctly?

I had the roofers out this fall to replace all my old fasteners, do some flashing work and put new roof vent boots on. I was looking out the dormer window and I noticed the boot was torn?? they installed. Is this an issue? The work is still under warranty. If they have to replace with another I already had them use oversize fasteners to replace the old. Will the new ones they install in the same holes be prone to lifting/leaking? I paid quite a bit of money for the work and I would like to not have to worry about anything for a long while. Thanks for the help both now and on my previous message this fall.

It looks like they tried to "make do" with a flashing that is too small for that diameter of pipe. I feel that it should be replaced with a properly sized flashing.

Hi Ron, Thanks for the question about metal roofing. Two things come to mind from the photo you attached: 1) It is important for a pipe boot to allow water to flow around it and not dam up the water between two ribs. It is difficult to tell from your photo if this is achieved. 2) The proper way to install this product is to start with the right size and then cut along a concentric circle to a size slightly smaller than the pipe so it fits snuggly. Regards, David

Call them back and have them re-do that work. The boot was either not sized properly or not cut on the correct relief properly. Either way, its sloppy work and will leak in the future as well as the issues that David noted with the water damming up on the backside of the pipe.

I believe the boot goes up on a "rib" as you can see closest to you in the picture. They are coming out tomorrow to review the work and fix. I saw where the boot should be installed on some installation guides turned to look like a diamond shape so water flows around it. If they do this then what about all the existing holes that will now be exposed with no boot over them. Also with the roof "rib" at the edge of the boot it looks like I will have water damming issues regardless. So what is the best way to install the new boot as far the attachment to the roof with the condition I have?

Here is another picture. They put a lot of screws in so I guess they will have to reuse the holes

They should re-use the holes.
