I recently inspected a roof in which the client says they are getting water intrusion into the ceiling and bathroom near windows. The contractor installed F-Style Drip Edges and I don’t believe it was installed correctly, channeling the water inside the home. Can someone please let me know if 1) drip edge was installed per standard. 2) The roof shingles installed correctly, as I see unusual bumps around roof penetrations, unusually small pieces of shingles,
and 3) If the attic is improperly ventilated. They installed power vents near the lower 1/3 of the low slope roof. The nails have condensation dripping from them. They also have ridge venting.
That isn’t the drip edge flashing causing that leak, Probably one of the penetrations that are done wrong. That bracket is improper too.
You can’t just shingle over penetrations like that. The flange needs to be interleaved with the lower portion of the flange exiting on top of the shingle. The antenna bracket is asking for trouble. It should be on top of the shingles if you’re going to have it at all. You can’ distort the lay of the shingles that way.
I can’t tell from the pictures, but it looks like the drip edge is installed under the roof decking. But Chuck is right, that isn’t the cause of the leak.
I would also think the power ventilators need to be higher up on the roof to actually be useful.
I’m sure that monkey donk around that threaded rod sticking up through the roof don’t help either.
Looks like the Monkey left a couple of dumps. Subject to leaks.
Needs repair Along with what Chuck said.
What were they thinking? LOL
Sounds like “raining in the attic” that happens due to improper ventilation and moist/humid air leaking into the attic during cold outdoor days. So what happens is the nails being below dew point (they are metal) start condensing humid air in the attic. Your job is to just identify the issue, let the contractor figure out how to fix it.
