Update: we've been cleaning and inspecting the roof and walls where the gutter, awning, and porch lights attach. This is what we have found that raises our suspicions.
There is a screw through the awning where it attaches to the gutter presumably to keep it from sliding fore and aft in the rail.
I'll cover that screw with proflex.
I pulled the plastic wire covers from the awning attachment and found this.
The top right quadrant of that hole has no sealant at all. It is where the worst part of the wallpaper blisters are, but the hole is near the bottom of the wall. I know water can flow upward through capillary action, but can it flow upwards of 5 feet or more?
We also noticed where the wires go through the wall for the led strip under the awning is poorly sealed.
I don't believe this is a cause of any damage though as it is on the other side of the door. It too will get some proflex.
My question is, what should I use to insure a good seal of the gutter to the roof. This is what I have on hand.
Do I need something else?
