Our home has some areas where the different pieces of roof meet the primary roof. These may or may not meet the criteria for "dormers." I recently had a local worker do some caulking & painting. I thought he was going to clear & seal these areas where the roof line meets another portion of the roof line. After he had completed the job I got home from work late & inspected the work the next am. There is still a 1 1/2 inch gap between the areas of intersecting roof lines. He replaced the flashing & caulked where he worked, but there is still open areas that are angled & go directly into my attic. These 4 areas a re approximately 12 to 18 inches in length & were infested with red wasps & a bird nest. The wasps do not bother us, but if they can get into my attic, I assume other insects & critters can too. Okay sorry for the history. Should I seal these areas? They are against the primary roof & might be considered dormer edges.
Typical Gap - A similar one is on the opposite side
