Exposed wood corner where new and old roof meet
Missing flashing or caulking where a roof addition meets an older section leaves wood exposed to potential water accumulation and dry rot over time. Because this spot is hidden from the ground, it often goes unnoticed until someone is on a ladder or the roof, raising concerns about long-term damage.

“Our roof was replaced close to a year ago due to hail damage. This was never noticed until this week as you can't see it without being on a ladder or on the roof. I feel like there should be some kind of flashing or at the very least caulking.”source ↗
