Roof question on older home.
My house has a 3 x 6 flat roof where the slanted roofs meet. The slanted roofs have gables, 4 of them. When we have a hard rain, water can come into the attic under this cap. The house as built in 1900 and it has 2 gable vents. In the year 2000, ridge vents were added. Was the 3 x 6 flat roof cap supposed to be passive ventilation? The roofer in 2016 did not put anything on the sides to prevent water from coming in. We had a “hard rain” and it did come in. Should it be flashed to prevent it and was it a way to ventilate the attic when it was first built, or am I just all wet. I seem to remember that my dad may have checked the attic when the rain was hard but, that was a very old memory and the house was owned by us since 1952. I have just clouded it up now. I am afraid of suffocating, as if the house is too closed up. Last night I opened windows.
