I’m just now starting my mock inspections and inspected a friends house so I’m just starting out. I was wondering what causes this issue normally. To me, it looks like sun damage has warped the flashing here. Or was it probably not nailed down properly? And how serious is this? Would you recommend immediate replacement?
Thanks
How subject to Ice damming is this particular spot?
If the answer is “It’s in Florida”, then no, not particularly serious. Those singles should go all the way back to the wall so any incidental water that might blow up there during a windy rain storm is unlikely to be an issue.
I’d recommend having it sealed down if anything.
I’d look a little closer to the drip edge at the eave though. Something seems amiss there.
I think it’s an illusion. Arrow points to the bottom of the drip edge. The dirt and shadows make it look odd though. Shingles look a little tattered.
Yeah, that’s what I was wondering about. I’m not saying it’s a bad, it just looks poorly done or something.
Very best practice is to not have to nail it down, but it is done frequently in my area. If it is nailed down, the nails need to be sealed on top with some silicone or roof tar. Some people put a superficial row of shingles over the top of the flashing to hide it. Again, if those shingles are nailed down, the nails will be exposed so they need to be sealed.
Do you have a picture from further back? I would need to see more of the “whole picture” in order to decide if it would make my report.
My thinking: Sure, some wind-driven rain could make it under the flashing. But, how much? Thinking “not much.” Would it cause a leak? Only if the underlayment did not do its job. Would I prefer nails? Nope, even if they have sealant applied, it is likely that the homeowner will not keep up with maintenance and, down the road, the nails are more likely to leak versus no nails. Same with vent flashing, I would prefer no nails personally - thank you.
To the Ice damming question, it is in Colorado, so yes, that could be a concern here. Here are a couple more photos showing the drip edge
Unlikely to be a problem in most areas but windblown rain could leak in. I’m particularly hard on those when a downspout from an upper roof elevation terminates onto it. I’ve found damage under such a location many times due to the increased amount of water dripping out and getting caught by the wind.
And ‘further back’ some more!
What exactly is that “roof” extending over?
Likely a ‘non-issue’ area… (pitch itself should make it a non-issue).
Not being properly secured/fastened to the shingles. Typically/usually roof nails secure the flashing at the bottom and top of the head wall flashing.
NOTE: A dab of sealant is typically/usually/normally applied to the heads of exposed nails/fasteners and lightly spread onto shingles. This is to prevent moisture penitration/protrusion following the shank of the fastener under the hole in the shingle into/onto the sheathing.
Observation: Awning/porch/deck roof - gable end Head Wall Flashing, sometimes referred to as an Apron Flashing.
Condition: Exposed Apron Flashing Wavy by appearance. The bottom of the flashing is not flush and secured atop the composition shingles.
No adverse conditions observed the day of the inspection.
Posable issues: Prone to wind driven weather and posable further movement.
Recommend: A licensed roofing contractor further evaluate and properly secure the head wall flashing. Act upon any recommendations therein.
Limitations: Observed from a ladder at the roof eave. The Awning/porch/deck roof deck was not mounted and traversed.
Hope that helps.
This is caused by installing the flashing without a hem on the edge, as metal does this when it’s not installed 100% straight.
