Welcome, my name is XXXXX XXXXX I will do my best to help you with your issue.
It looks like neither edge of the flashing is tucked under the shingles. At a minimum it should be tucked under the shingles on the high side of the roof slope
The way this roof collar is installed there's nothing to stop water from running under the flashing even if they stuck it down with roofing cement
It's hard to tell from the pic but even if the high side is tucked under the shingle it's still not the proper way to do this. There should be at least 1 course of shingle over the sides as well as the leading edge.
It looks like this may be a new roof. If that's the case it would have been a breeze to do this properly.
yes, its a new roof. Am not a roofer, but it didnt look right to me. been having to watch these guys like a hawk!
Can you tell me what kind of paint is to be used on the flashings and stacks?
Talking more about the cosmetic color of the vent pipes and vents. To help tie in the color with the roof shingles
Any paint that is compatible with the surface being painted. You would need to use different paint for a PVC plumbing stack than a copper or cast iron stack for example. There are no paints specifically for this purpose.
Can you review these additional pics to see if there is anything more to be concerned about? I didnt include the obvious ones like installing the starter shingles upside down with no overhang over drip edge, nailing through the outside of the drip edge, sloppy cuts on shingles, etc. This guy was fired today from his company, now I need to make sure things get corrected.
